In order to improve the uniformity of the display panel, the inventor has conducted the following research on the display panel in the prior art:
referring to fig. 1 to 4, fig. 1 is a schematic plan view illustrating a display panel provided in the prior art, fig. 2 is an enlarged schematic view of the display panel provided in fig. 1 in a region W, fig. 3 is a signal waveform diagram of the display panel provided in fig. 1, and fig. 4 is another signal waveform diagram of the display panel provided in fig. 1. As shown in fig. 1 to 4, the display panel includes a substrate 00 and a display area AA, and the display area AA includes: the display panel comprises a grid line 01, touch electrodes 02, electrode notches 03, a driving chip 04 and pixel electrodes 05, wherein the grid line 01 comprises a first grid line 011 and a second grid line 012, the pixel electrodes 05 comprise a first pixel electrode 051 and a second pixel electrode 052, the first grid line 011 is electrically connected with the first pixel electrode 051, the second grid line 012 is electrically connected with the second pixel electrode 052, the touch electrodes 02 cover the first grid line 011, the electrode notches 03 are arranged between every two adjacent columns of touch electrodes 02, the electrode notches 03 comprise a second grid line 012, and the touch electrodes 02 are reused as common electrodes in a display stage. Since the touch electrode 02 and the gate line one 011 are overlapped, a coupling capacitor C1 exists between the touch electrode 02 and the gate line 011; since there is no overlap between the second gate line 012 and the touch electrode 02 in the electrode slit 03, the coupling capacitance C2 between the second gate line 012 and the touch electrode 02 in the electrode slit 03 is smaller than C1. In the case of different coupling capacitances, the voltage of the touch electrode 02 is not uniform, and the touch electrode 02 is reused as a common electrode, so that the display brightness of the display panel is not uniform in the display stage.
One scanning method provided in the prior art is: the display panel needs to be scanned forward and backward in displaying. Assuming that there are M gate lines, so-called normal scan, a gate driving circuit (not shown) provides a driving signal to the gate line 01 in the direction Y1, that is, the gate driving circuit provides the driving signals in the order from the 1 st gate line (the gate line farthest from the driving chip 04) to the mth gate line (the gate line closest to the driving chip 04); the reverse scan is a process in which the gate driver circuit supplies a drive signal to the gate line 01 in a direction Y2 completely opposite to the direction Y1, that is, the gate driver circuit supplies a drive signal in the order from the mth gate line (the gate line farthest from the driver chip 04) to the 1 st gate line (the gate line farthest from the driver chip 04).
With continued reference to fig. 1-3, the following illustrates the problem that occurs when the driving chip 04 performs brightness compensation during the forward scan and the reverse scan of the display panel.
In general, the position of the second gate line 012 in the electrode slit 03 can be calculated according to the resolution of the display panel and the size of the touch electrode 02. Since the position of the electrode slit 03 is not changed, the position of the second gate line 012 in the electrode slit 03 is fixed. As shown in fig. 3-4, fig. 3-4 shows the corresponding relationship between the coupling capacitance C and the data signal DA when the display panel is in the forward scanning and the reverse scanning, the coupling capacitance between the first gate line 011 covered by the touch electrode 02 and the touch electrode 021 is C1, the coupling capacitance between the second gate line 012 and the touch electrode 021 in the electrode slit 03 is C2, and C2< C1; the data signal DA received by the pixel electrode 051 controlled by the first gate line 011 is the first data signal DA1, the data signal DA received by the pixel electrode 052 controlled by the second gate line 012 is the second data signal DA2, and DA2< DA 1. When the display panel is in the normal scan state, the coupling capacitance C2 between the second gate line 012 and the touch electrode 021 is smaller than the coupling capacitance C1 between the first gate line 011 and the touch electrode 021, so to compensate the brightness difference caused by the coupling capacitance, brightness compensation needs to be performed on the pixel electrode 05 controlled by the second gate line 012, that is, the second data signal DA2 needs to be transmitted to the pixel electrode 052, and the pixel electrode 052 is the last row of pixel electrodes covered by the touch electrode 021; when the display panel is in the reverse scan state, the coupling capacitance C2 between the second gate line 012 and the touch electrode 021 is smaller than the coupling capacitance C1 between the first gate line 011 and the touch electrode 021, so the pixel electrode 05 controlled by the second gate line 012 still needs to be subjected to brightness compensation, that is, the data signal DA required to be transmitted to the pixel electrode 052 still is the second data signal DA2, but the pixel electrode 052 is the first row of pixel electrodes covered by the touch electrode 021. That is, the position of the pixel electrode 05 that needs to be subjected to the luminance compensation is changed for the same touch electrode 02. When the driving chip 04 performs brightness compensation on the display panel, the positions of the touch electrode 021 where the brightness compensation is required during the forward scanning and the reverse scanning are not the same, so the driving chip 04 also needs to calculate the position of the pixel electrode 05 for compensation. Specifically, as shown in fig. 1, 3, and 4, for the touch electrode 021, the pixel row requiring brightness compensation is the last row during the forward scan, but the pixel row requiring brightness compensation is the first row during the reverse scan. For the driver chip 04, switching from the forward scanning direction Y1 to the reverse scanning direction Y2, i.e. switching the forward scanning mode to the reverse scanning mode, the driver chip 04 needs to recalculate the position of the pixel electrode 05 that needs to be subjected to the brightness compensation, and if the position is not recalculated, the brightness compensation will be wrong, which undoubtedly greatly increases the design difficulty of the driver chip 04, thereby increasing the design cost of the driver chip 04.
In view of the above, the present invention provides a display panel, a display device and a driving method of the display panel to solve the problems in the prior art. With respect to embodiments of the display panel, the display device, and the driving method of the display panel provided by the present invention, the following will be described in detail.
Referring to fig. 5-6, fig. 5 is a schematic plan view of a display panel according to an embodiment of the invention, and fig. 6 is a schematic cross-sectional view of the display panel shown in fig. 5 along a sectional line OO'. As shown in fig. 5 to 6, an embodiment of the present invention provides a display panel, including: a substrate 1, and a plurality of gate lines 2 located on the substrate 1, the plurality of gate lines 2 extending in a row direction X and arranged in a column direction Y; the touch control device comprises a plurality of mutually insulated touch control electrodes 3, wherein the touch control electrodes 3 are positioned on one side, away from a substrate 1, of a gate line 2, the touch control electrodes 3 are arranged along a column direction Y, a first notch 4 is formed between every two adjacent touch control electrodes 3 along the column direction Y, the first notch 4 extends along a row direction X, and in the direction perpendicular to a display panel, the first notch 4 is overlapped with the two gate lines 2.
Specifically, as shown in fig. 5 to 6, in the display panel provided in this embodiment, the touch electrodes 3 are arranged along the column direction Y, the touch electrodes 3 cover the plurality of gate lines 2, a first slit 4 is formed between two adjacent touch electrodes 3, and two gate lines 2 are disposed at positions corresponding to the first slit 4. It should be noted that the embodiments of the present invention are only exemplified by fig. 5 to 6, and the present invention does not specifically limit the type of the touch electrode, the number of rows of pixel electrodes (not shown) covered by the touch electrode, and the like.
The following illustrates the brightness compensation of the display panel provided in this embodiment. The position of the gate line 2 in the first slit 4 and the pixel electrode controlled by the gate line 2 in the first slit 4 can be calculated according to the size of the touch electrode 3 and the resolution of the display panel, and at this time, the pixel electrodes controlled by the two gate lines 2 in the first slit 4 can be subjected to brightness compensation according to the position of the first slit 4. For example, as shown in fig. 5, the position of the first slit 4 is not changed, and thus, the position of the gate line 2 in the first slit 4 is fixed. When the two adjacent rows of touch electrodes 3 form the first slit 4, the two gate lines 2 in the first slit 4 are not overlapped with the touch electrodes 3, and the display panel provided in this embodiment performs brightness compensation on the display frames corresponding to the two gate lines 2 in the first slit 4. For example, as shown in fig. 5, if the display panel has four rows of touch electrodes 3, two sides of the second row of touch electrodes 3 and two sides of the third row of touch electrodes 3 have first slits 4, that is, for the same touch electrode 3 located in the middle of the display panel, the display frames to be compensated are the display frames corresponding to two gate lines 2 closer to the touch electrode 3 in the two first slits 4, that is, the first row of display frames and the last row of display frames covered by the touch electrode 3. Therefore, when the display panel is in the normal scanning state, the display frames required to be subjected to brightness compensation are the first row display frame and the last row display frame covered by the touch electrode 3 respectively; when the display panel is in the reverse-scanning state, the display frames required to be subjected to brightness compensation are still the first row display frame and the last row display frame covered by the touch electrode 3. That is to say, no matter the display panel is in the normal scanning state or the reverse scanning state, the position of the display screen requiring brightness compensation is not changed, and therefore, it is not necessary to calculate the position of the display screen requiring brightness compensation by adopting another method again, and the brightness compensation performed on the display screen is not wrong, so that the correctness of the brightness compensation of the display screen is ensured, and meanwhile, the calculation method of the brightness compensation of the display panel provided by the embodiment is simpler.
In the display panel provided by this embodiment, the two gate lines are disposed in the first slit, and the two gate lines are not overlapped with the touch electrode, so that the coupling capacitances of the two gate lines and the touch electrode in the first slit are equal or similar, the display panel provided by the embodiment of the present invention can perform brightness compensation on the display frames corresponding to the two gate lines in the first slit according to the position of the first slit, and for the touch electrode located at the middle position of the display panel, no matter the display panel is in a forward scanning state or a reverse scanning state, not only can correct brightness compensation be performed on the display panel, thereby avoiding brightness compensation errors, improving the uniformity of the brightness of the display panel, and improving the display quality of the display panel, but also because the position in the display frame where brightness compensation is required is not changed, it is not necessary to calculate the position in the display frame where brightness compensation is required again by using other methods, namely, the calculation mode of performing brightness compensation on the display picture is simpler, and the calculation amount of the driving chip is reduced, so that the manufacturing cost of the display panel is reduced.
Optionally, with continued reference to fig. 5, the widths W1 and W2 of the two gate lines 2 in the first slit 4 are equal.
In the display panel provided by this embodiment, the widths of the two gate lines in the first slit are equal, so that the capacitances between the two gate lines in the first slit and other electronic components are the same, thereby avoiding affecting the uniformity of the brightness of the display panel.
Optionally, please continue to refer to fig. 5, the touch electrode 3 is reused as a common electrode. It can be understood that the working principle of the touch electrode 3 provided in this embodiment may be a mutual capacitance type or a self-capacitance type, and the invention does not specifically limit the working principle of the touch electrode, and the shape and size of the touch electrode.
In the display panel provided in this embodiment, the touch electrode and the common electrode are multiplexed, and specifically, when the display panel performs a display function, the touch electrode receives a common voltage signal; when the display panel executes a touch function, the touch electrode receives a touch signal. The display panel provided by the embodiment does not need to be additionally provided with the common electrode, so that the thickness of the display panel is reduced, and the display panel is light and thin; and, because the electrode layer is arranged less, the penetration rate of the display panel is improved.
Alternatively, referring to fig. 7-8, fig. 7 is a schematic plan view of another display panel provided in the embodiment of the present invention, and fig. 8 is a schematic cross-sectional view of the display panel provided in fig. 7 along a sectional line PP'. As shown in fig. 7-8, two adjacent touch electrodes 3 in the column direction Y include a first touch electrode 31 and a second touch electrode 32, and two gate lines 2 overlapping in the first slit 4 are a first gate line 21 and a second gate line 22, respectively; the display panel further includes a plurality of first pixel electrodes 51, a plurality of second pixel electrodes 52, and a plurality of data lines 6, wherein the first pixel electrodes 51 and the second pixel electrodes 52 are located on a side of the gate line 2 away from the substrate 1, the first pixel electrodes 51 and the second pixel electrodes 52 are adjacently disposed along the column direction Y, the plurality of first pixel electrodes 51 are arranged along the row direction X, the plurality of second pixel electrodes 52 are arranged along the row direction X, the data lines 6 extend along the column direction Y, and the plurality of data lines 6 are arranged along the row direction X; in a direction perpendicular to the display panel, the first pixel electrode 51 overlaps the first touch electrode 31, and the second pixel electrode 52 overlaps the second touch electrode 32; the display panel further includes a plurality of first switches 71 and a plurality of second switches 72, the plurality of first switches 71 are arranged along the row direction X, the plurality of second switches 72 are arranged along the row direction X, a control terminal G1 of the first switch 71 is electrically connected to the first gate line 21, a first pole S1 of the first switch 71 is electrically connected to the data line 6, a second pole D1 of the first switch 71 is electrically connected to the first pixel electrode 51, a control terminal G2 of the second switch 72 is electrically connected to the second gate line 22, a first pole S2 of the second switch 72 is electrically connected to the data line 6, and a second pole D2 of the second switch 72 is electrically connected to the second pixel electrode 52.
Specifically, as shown in fig. 7-8, the first pixel electrode 51 in the last row covered by the first touch electrode 31 is controlled by the first gate line 21, the second pixel electrode 52 in the first row covered by the second touch electrode 32 is controlled by the second gate line 22, and the first gate line 21 and the second gate line 22 are located in the first slit 4. When the display panel is in a normal scan state, the last row of first pixel electrodes 51 controlled by the first gate lines 21 is brightness compensated, and the first row of second pixel electrodes 52 controlled by the second gate lines 22 is brightness compensated; when the display panel is in the reverse scan state, the last row of second pixel electrodes 52 controlled by the second gate lines 22 is luminance-compensated, and the first row of first upper pixel electrodes 51 controlled by the first gate lines 21 is luminance-compensated.
In the display panel provided by the embodiment, no matter the display panel is in the forward scanning state or the reverse scanning state, the display panel respectively performs brightness compensation on the first pixel electrode controlled by the first grid line and the second pixel electrode controlled by the second grid line in the first slit, so that the brightness uniformity of the display panel is improved, the display performance of the display panel is improved, and the display quality of the display panel is improved.
Alternatively, with continued reference to fig. 7-8, the shape of the first switch 71 is axisymmetric to the shape of the second switch 72. Alternatively, the control terminal G1 of the first switch 71 is located at a side of the first gate line 21 facing the first pixel electrode 51, and the control terminal G2 of the second switch 72 is located at a side of the second gate line 22 facing the second pixel electrode 52. The gate line includes a side close to the pixel electrode and a side far away from the pixel electrode, and the side facing the pixel electrode is the side close to the pixel electrode.
Specifically, as shown in fig. 7 to 8, in order to make the coupling capacitance between the touch electrode 3 and the pixel electrode 5 uniform, the shape of the first switch 71 and the shape of the second switch 72 are axisymmetric. The first gate line 21 includes a side close to the first pixel electrode 51 and a side far from the first pixel electrode 51, and the control terminal G1 of the first switch 71 is located at the side of the first gate line 21 close to the first pixel electrode 51; the second gate line 22 includes a side close to the second pixel electrode 52 and a side far from the second pixel electrode 52, and the control terminal G2 of the second switch 72 is located at the side of the second gate line 22 close to the second pixel electrode 52. Alternatively, the shapes of the first pixel electrode 51 and the second pixel electrode 52 are also axisymmetric, and the first pixel electrode 51 and the second pixel electrode 52 do not overlap the first slit 4 in a direction perpendicular to the display panel.
It should be understood that, in this embodiment, only the shape of the first switch 71 and the shape of the second switch 72 are schematically illustrated by taking fig. 7 to 8 as an example, and there are many methods for making the shape of the first switch 71 and the shape of the second switch 72 be axisymmetric, which are not repeated herein.

Optionally, referring to fig. 7 again, the number of the first pixel electrodes 51 overlapped with the first touch electrodes 31 is M, the number of the second pixel electrodes 52 overlapped with the second touch electrodes 32 is N, and M and N satisfy: and M is N.

As shown in fig. 13 to 16, the present invention further provides a driving method of a display panel, for driving the display panel provided by the present invention, the display panel includes a plurality of pixels 8 and a driving chip 9, optionally, the pixels 8 include at least two sub-pixels with different colors, and the driving chip 9 is electrically connected to the data line 6 to perform brightness compensation on the display panel. It is to be understood that, for clearly illustrating the technical solution of the present embodiment, the data line 6 is not illustrated in fig. 13, and the manner of disposing the data line 6 in any embodiment of the present invention may be referred to for the manner of disposing the data line 6, which is not described herein again.
The driving method comprises the following steps:
s1: the method comprises the steps of including at least one forward scanning stage Z and at least one reverse scanning stage F in one frame time;
s2: in the forward scanning phase Z, sequentially providing forward scanning signals to the gate lines 2, wherein when the forward scanning signals are provided to the gate lines 2 not overlapping with the first cuts 4, the electrical signal DATA received by the DATA line 6 is a first forward electrical signal Z1, and the brightness of the pixel 8 is a first brightness, when the forward scanning signals are provided to the gate lines 2 overlapping with the first cuts 4, the electrical signal DATA received by the DATA line 6 is a second forward electrical signal Z2, and the brightness of the pixel 8 is a second brightness, and when the first brightness is the same as the second brightness, the second forward electrical signal Z2 is smaller than the first forward electrical signal Z1;
s3: in the reverse scan phase F, the reverse scan signals are sequentially supplied to the gate lines 2, wherein when the reverse scan signals are supplied to the gate lines 2 not overlapping the first slits 4, the electrical signal DATA received by the DATA line 6 is the first reverse electrical signal F1, and the brightness of the pixel 8 is the third brightness, and when the reverse scan signals are supplied to the gate lines 2 overlapping the first slits 4, the electrical signal DATA received by the DATA line 6 is the second reverse electrical signal F2, and the brightness of the pixel 8 is the fourth brightness, and when the third brightness is the same as the fourth brightness, the second reverse electrical signal F2 is smaller than the first reverse electrical signal F1.
Specifically, please refer to fig. 13-16, which illustrate the reason for the difference between the coupling capacitances CC: the overlapping area of the gate line 2 and the touch electrode 3, which do not overlap the first slit 4, is large, and thus, the coupling capacitance CC1 between the gate line 2 and the touch electrode 3 is large, while the overlapping area of the gate line 2 and the touch electrode 3 within the first slit 4 is small, and thus, the coupling capacitance CC2 between the gate line 2 and the touch electrode 3 is small.
When the display panel is in the forward scanning phase Z, since the coupling capacitance CC2 between the gate line 2 and the touch electrode 3 in the first slit 4 is small, the load of the touch electrode 3 is small, and when the touch electrode 3 is multiplexed as a common electrode, the voltage on the common electrode is large, so that the luminance of the pixel 8 controlled by the gate line 2 in the first slit 4 is large, which is equivalent to that of the electrical signal received on the data line 6 being high, and therefore, when the luminance of the display of the pixel 8 is the same, it is necessary to transmit a small electrical signal to the data line 6 electrically connected to the gate line 2 in the first slit 4 and transmit a large electrical signal to the data line 6 electrically connected to the gate line 2 not in the first slit 4, so that the luminance of the display panel can be uniform.
No matter the display panel is in the forward scanning stage Z or the reverse scanning stage F, for the touch electrode located in the middle of the display panel, the first slits 4 are respectively arranged on both sides of the same touch electrode, and the coupling capacitance CC2 between the gate line 2 and the touch electrode 3 in the first slit 4 is smaller than the coupling capacitance CC1 between the other gate line 2 and the touch electrode, so that, no matter in the forward scanning stage Z or the reverse scanning stage F, the luminance compensation needs to be performed on the pixel 8 controlled by the gate line 2 in the first slit 4, and for the same touch electrode 3 located at the middle position MID of the display panel, the display pictures needing to be compensated are the display pictures corresponding to the two gate lines 2 closer to the touch electrode 3 in the two first slits 4, that is, namely, the first row display picture and the last row display picture covered by the touch electrode 3. The compensation method of the backward scanning stage F is the same as that of the forward scanning stage Z, and is not described herein again.
In the driving method of the display panel provided in this embodiment, two gate lines are disposed in the first slit, and since the two gate lines and the touch electrodes are not overlapped, the coupling capacitances between the two gate lines and the touch electrodes in the first slit are equal or similar, in the driving method of the display panel provided in this embodiment, for the touch electrode located in the middle of the display panel, no matter the display panel is in the forward scanning stage or the reverse scanning stage, the pixel controlled by the gate line in the first slit is used for performing brightness compensation, which not only does not cause brightness compensation error, but also improves the uniformity of the brightness of the display panel, improves the display performance of the display panel, and improves the display quality of the display panel, and because the position in the display frame, which needs to be performed brightness compensation, is not changed, it is not necessary to calculate the position in the display frame, which needs to be performed brightness compensation, by other methods again, namely, the calculation mode of performing brightness compensation on the display picture is simpler, and the calculation amount of the driving chip is favorably reduced.

If the gate line 2 does not overlap the first slit 4, determining the value of the electrical signal DATA transmitted to the DATA line 6 according to the first luminance voltage comparison table TA1 and the luminance required by the current pixel 8; if the gate line 2 overlaps the first slit 4, the value of the electrical signal DATA transmitted to the DATA line 6 is determined according to the second luminance voltage comparison table TA2 and the luminance required by the current pixel 8.
