The display panel has a plurality of pixels and a plurality of data lines, and the pixels are arranged in a matrix, and each of the data lines is electrically coupled to a part of the pixels. In this method, first, the display data to be transmitted by the same data line is divided into a plurality of groups in chronological order. Each group contains display data of N pixels, N is a natural number and is greater than or equal to 3, and the display data in the same group causes the display voltages of the corresponding pixels to exhibit the same polarity, and the same data line The display data of the adjacent two groups will cause the display voltages of the corresponding two groups of pixels to exhibit different polarities. At the same time, the display data to be transmitted by the adjacent two data lines causes the display voltages of the corresponding two pixels to exhibit different polarities. Then, all the pixels are turned on during the display period of the screen, and the corresponding display data is loaded into the pixels through the data line.

The invention further provides a display device. The display device includes a display panel, a data driver, a scan driver and a timing controller. The display panel has a plurality of pixels, a plurality of scan lines and a plurality of data lines. The pixels are arranged in a matrix, and each pixel is electrically coupled to one of the scan lines and one of the data lines. The data driver is electrically coupled to the data line, and the scan driver is electrically coupled to the scan line. As for the timing controller, the display data to be transmitted by the same data line is divided into a plurality of groups in chronological order, wherein each group includes display data of N pixels, and N is a natural number and is greater than or equal to 3. The display data in the same group will cause the display voltages of the corresponding pixels to exhibit the same polarity, and the display data of the adjacent two groups on the same data line will cause the display voltages of the corresponding two groups of pixels to exhibit different polarities. At the same time, the display data to be transmitted by the adjacent two data lines causes the display voltages of the corresponding two pixels to exhibit different polarities. In addition, the timing controller is further configured to open all the pixels through the scan driver during a display period, and drive the corresponding data lines through the data driver to load the corresponding display data into the pixels.

According to an embodiment of the driving method of the present invention and an embodiment of the display device of the present invention, in the pixels corresponding to each group, the first display material of the pixel to be loaded by the data is executed. The transmission time is extended by the first preset time, and the pixel corresponding to each group is delayed by the first preset time.

According to an embodiment of the driving method of the present invention and an embodiment of the display device of the present invention, the first preset time is a scan time of one scan line.

According to an embodiment of the driving method of the present invention and an embodiment of the display device of the present invention, in the pixels corresponding to each group, the opening time of the first pixel for performing data loading is extended. The second preset time, and the opening times of the pixels corresponding to each group do not overlap each other.

According to an embodiment of the driving method of the present invention and an embodiment of the display device of the present invention, the two groups of pixels corresponding to the display materials of the adjacent two groups on the same data line are located in different rows.

Since N is greater than 2 and less than the total number of pixels in a row, when the display panel is driven by the scanning frequency of 120 Hz and the N-point inversion, the display panel does not have excessive power consumption, and the data The driver will not overheat, and the charging misalignment caused by the RC signal delay will be improved. In this way, the disadvantages caused by the conventional method of driving the display panel in a two-point inversion manner are improved. In addition, since N is greater than 2 and less than the total number of pixels in a row, when the display panel is driven by the scanning frequency of 120 Hz and the N-point inversion, the tolerance of the display panel to vertical crosstalk is higher. The display panel when the display panel is driven in a row inversion manner is good for the vertical crosstalk, thereby improving the conventional disadvantages of driving the display panel in a row inversion manner.

The above and other objects, features and advantages of the present invention will become more <RTIgt;

First embodiment:

1 is an explanatory view of a driving method according to an embodiment of the present invention. Referring to FIG. 1, the driving method is adapted to drive a display panel 100. The display panel 100 has a plurality of pixels (as indicated by the symbol 110) and a plurality of data lines (as indicated by the numerals 121 to 128). The pixels are arranged in a matrix, and each data line is electrically coupled to a part of the pixels. In Fig. 1, each pixel is marked with a positive sign or a negative sign to indicate the polarity that the display voltage of each pixel will be presented during the picture display period of a certain picture. On the other hand, it is understood that the driving method of the display voltage of the pixel is to drive the display panel 110 by a 4-point inversion method.

In order to achieve the above polarity configuration, the display data to be transmitted by the same data line (as indicated by the symbol 130) must be chronologically divided into 4 groups (as indicated by the symbol 140), and each group contains There are 4 pixels of display data. As shown in FIG. 1, among the display materials to be transmitted by the same data line, the display material closer to the display panel 110 is transmitted earlier. In addition, the display data in the same group must be such that the display voltages of the corresponding pixels exhibit the same polarity, and the display data of the adjacent two groups on the same data line must make the display voltages of the corresponding two groups of pixels exhibit different polarities. Taking the first two sets of display data to be transmitted by the data line 121 as an example, the first set of display data to be transmitted by the data line 121 (both marked with a positive sign) must enable the data line 121 to be electrically coupled to the first four columns of pixels. The display voltages are all positive, and the second set of display data (both marked with a negative sign) to be transmitted by the data line 121 must be such that the data lines 121 are electrically coupled to the fifth to eighth columns of pixels. The display voltage is negative.

In addition, at the same time, the display data to be transmitted by the adjacent two data lines must be such that the display voltages of the corresponding two pixels exhibit different polarities. For example, the first display data to be transmitted by the data line 121 and the first display data to be transmitted by the data line 122 are taken as an example. The first display data to be transmitted by the data line 121 must be electrically coupled to the data line 121. The display voltage of the first column of pixels is positive, and the first display data to be transmitted by the data line 122 must be such that the display voltage of the first column of pixels electrically coupled to the data line 122 is negative. Row.

By the arrangement and planning of the display materials described above, the pixels can be turned on from top to bottom in the screen display period of the above-mentioned screen, so that the data lines can be sequentially arranged according to the time sequence of the displayed data to be transmitted. Load the displayed data into the opened pixels.

In this example, since the display panel 100 is driven by the 4-point inversion method, the display panel 100 does not have excessive power consumption when the scanning frequency of the display panel 100 reaches 120 Hz (or more). The phenomenon, and the data driver (not shown) will not overheat, and the data line and the gate line (not shown) due to the delay of the RC signal will also improve the charging misalignment. Thus, the disadvantages caused by the conventional method of driving the display panel 100 in a two-point inversion manner are improved. In addition, since this example is to drive the display panel 100 in a 4-point inversion manner, when the scanning frequency of the display panel 100 reaches 120 Hz (or more), the display panel 100 is resistant to vertical crosstalk. The display panel 100 is more resistant to vertical crosstalk than when the display panel 100 is driven in a row reversal manner, thereby improving the conventional disadvantages of driving the display panel 100 in a row inversion manner.

Although in this example, each group contains display material of 4 pixels, those skilled in the art should know that each group can contain display data of N pixels, as long as N is The natural number is greater than or equal to 3. Moreover, the number of pixels cited in this example is not intended to limit the invention.

Second embodiment:

The difference between this example and the first embodiment is that in the pixels corresponding to each group, the transmission time of the display data of the first pixel to be loaded with the data is extended by the first preset time, and The pixels corresponding to each group are opened after the first preset time is delayed. The first preset time is, for example, the scan time of one scan line, which will be described with reference to FIG. 2, and the display data of each group including 4 pixels is also taken as an example.

2 is an explanatory diagram of a driving method according to another embodiment of the present invention. In Fig. 2, the indications G1 to G8 are indicated as scan pulses transmitted on eight consecutive scan lines, and the designation T is indicated as the pulse enable period of the scan pulse. Each scan pulse is used to turn on a corresponding column of pixels. In addition, the mark H is indicated as the scan time of one scan line, that is, the time during which the data driver (not shown) provides the display data for each column of pixels in one screen display period.

Referring to FIG. 2, since the display data of the adjacent two groups on the same data line must make the display voltages of the corresponding two groups of pixels exhibit different polarities, the data line starts from the cutoff time 202 of the scan time H corresponding to the scan pulse G4. The data voltage of the transmitted display data will start to change, that is, the display data of the fifth column of the eight columns of pixels will be transmitted. However, due to the delay of the RC signal, the data voltage on the data line cannot be charged to a predetermined level before the rising edge of the next scan pulse (indicated by a broken line), thereby causing charging misalignment. In order to solve this problem, the transmission time of the display data of the fifth column of pixels can be extended by one scan time H (even if the display data of the fifth column of pixels is transmitted for two scan times H), and the fifth column of pixels is The eight columns of pixels are delayed by one scan time H.

It is worth mentioning that such an approach does not necessarily occupy the blanking period between the two adjacent screen display periods. Fig. 3 is an explanatory diagram of a blank period. As shown in FIG. 3, there is a blank period between the screen display period of the Kth screen and the screen display period of the K+1th screen, where K is a natural number. During each display period, each column of pixels is turned on once to charge and load the corresponding display data, so each screen display period is evenly distributed into a plurality of scan times H. No pixels are turned on during the blank period. Therefore, in the case of the method of this example, if the length of time for each screen display period is to be fixed, then the time length of the scan time H can be re-allocated.

Third embodiment:

The difference between this example and the first embodiment is that in the pixels corresponding to each group, the opening time of the first pixel for performing data loading is extended by the second preset time, and each group The opening times of the corresponding pixels do not overlap each other. This will be explained with reference to Fig. 4, and the display data of each group containing 4 pixels is also taken as an example.

4 is an explanatory diagram of a driving method according to still another embodiment of the present invention. In FIG. 4, the indications G1 to G8 are indicated as the scan pulses transmitted on the eight consecutive scan lines, and the designation T and the indication T+Δ are both indicated as the pulse enable period of the scan pulse. Each scan pulse is used to turn on a corresponding column of pixels. In addition, the mark H is indicated as the scan time of one scan line, that is, the time during which the data driver (not shown) provides the display data for each column of pixels in one screen display period.

Referring to FIG. 4, since the display data of the adjacent two groups on the same data line must make the display voltages of the corresponding two groups of pixels exhibit different polarities, the data line starts from the cutoff time 402 of the scan time H corresponding to the scan pulse G4. The data voltage of the transmitted display data will start to change, that is, the display data of the fifth column of the eight columns of pixels will be transmitted. However, due to the delay of the RC signal, the data voltage on the data line cannot be charged to a predetermined level before the rising edge of the scanning pulse G5, thereby causing charging misalignment. In order to solve this problem, the pulse enable period of the scan pulse G5 can be extended from T to T + Δ.

It is worth mentioning that since the pulse enable period of each scan pulse does not occupy the entire scan time H, such a method does not occupy the blank period between the display periods of the two adjacent pictures.

Fourth embodiment:

The difference between this example and the first embodiment lies in that the two groups of pixels corresponding to the display materials of the adjacent two groups on the same data line are located in different rows. This will be explained with reference to FIG. 5, and the display data of each group containing 4 pixels is also taken as an example.

Fig. 5 is an explanatory view showing a driving method according to still another embodiment of the present invention. Referring to FIG. 5, the driving method is adapted to drive a display panel 500. The display panel 500 has a plurality of pixels (as indicated by the symbol 510) and a plurality of data lines (as indicated by the numerals 521 to 529). The pixels are arranged in a matrix, and each data line is electrically coupled to a part of the pixels. In FIG. 5, each pixel is marked with a positive sign or a negative sign to indicate the polarity at which the display voltage of each pixel is to be presented during the picture display period of a certain picture.

Please refer to FIG. 5 and FIG. 1 at the same time. After comparison, it can be found that the arrangement and planning of the display data of the two are the same, the difference is that the pixel of FIG. 5 is electrically coupled in a zigzag manner. The data lines are such that the two groups of pixels corresponding to the display materials of the adjacent two groups are located in different rows.

The pixel arrangement shown in FIG. 5 can solve the problem of uneven brightness, which is illustrated in FIG. 6. Fig. 6 is an explanatory diagram of uneven brightness. In FIG. 6, reference numerals 602, 604, and 606 are shown as pixel electrodes of three consecutive pixels in the same row, reference numeral 608 is represented as a parasitic capacitance between pixel electrodes 602 and 604, and reference numeral 610 is represented as a picture. The parasitic capacitance between the electrodes 604 and 606. In Fig. 6, each pixel electrode is marked with a positive sign or a minus sign to indicate the polarity that each pixel electrode will exhibit during the picture display period of a certain picture.

Referring to FIG. 6, the polarity of the pixel electrode 604 is changed from a negative polarity to a positive polarity due to the polarity inversion operation. Since the voltage across the capacitor cannot be changed instantaneously, when the pixel electrode 604 is changed from the negative polarity to the positive polarity, the potential of the pixel electrode 602 is also raised, and the pixel to which the pixel electrode 602 belongs becomes brighter. Since the polarity of the pixel electrode 606 is changed from a positive polarity to a negative polarity, when the polarity of the pixel electrode 606 is changed from a positive polarity to a negative polarity, the potential of the pixel electrode 604 is also pulled down, thereby causing the drawing. The pixel to which the element electrode 604 belongs becomes darker. In other words, if the adjacent two pixels in the same row all exhibit the same polarity, the later driven pixels will make the first driven pixels become brighter; otherwise, if they are in the same row, the adjacent two. The pixels are in different polarities, so later driven pixels will make the first driven pixels darker. In this way, the brightness of the picture will be uneven.

Referring again to FIG. 5, since the pixels shown in the figure are specially configured, the same line of pixels will only exhibit one polarity, and the pixels of the same line will have the same brightness.

Fifth embodiment:

This example differs from the first embodiment in that the pixels corresponding to the display materials of the same group are alternately arranged in adjacent two rows, and the adjacent two pixels corresponding to the group boundary are located in the same row. This will be explained with reference to FIG. 7A and FIG. 7B, and similarly, display data of four pixels per group is taken as an example.

Please refer to FIG. 7A first. Fig. 7A is an explanatory view showing a driving method according to still another embodiment of the present invention. This driving method is suitable for driving a display panel 700A. The display panel 700A has a plurality of pixels (as indicated by the symbol 710A) and a plurality of data lines (as indicated by the numerals 721A to 728A). The pixels are arranged in a matrix, and each data line is electrically coupled to a part of the pixels. In Fig. 7A, each pixel is marked with a positive sign or a negative sign to indicate the polarity at which the display voltage of each pixel is to be presented during the picture display period of a certain picture.

Please refer to FIG. 7A and FIG. 1 at the same time. After comparison, it can be found that the arrangement and planning of the display data of the two are the same, except that the pixel of FIG. 7A is also electrically coupled in a zigzag manner. Information line. As shown in FIG. 7A, the pixels corresponding to the display data of the same group are alternately arranged in two adjacent rows, and the adjacent two pixels corresponding to the group boundary are located in the same row. In this way, the polarities of the same row of pixels are arranged in a dot inversion manner, and the polarities of the same column of pixels are also arranged in a dot inversion manner.

The pixel shown in Fig. 7A is subjected to the aforementioned special configuration, and such a configuration is also used to solve the aforementioned problem of uneven brightness. As shown in FIG. 7A, such a configuration causes the polarity of the same line of pixels to alternately positive and negative, thereby making the pixel brightness of the same line uniform.

Fig. 7B is also an explanatory view of a driving method according to still another embodiment of the present invention. Referring to FIG. 7B, the driving method is adapted to drive a display panel 700B. The display panel 700B has a plurality of pixels (as indicated by the symbol 710B) and a plurality of data lines (as indicated by the numerals 721B to 727B). The pixels are arranged in a matrix, and each data line is electrically coupled to a part of the pixels. In Fig. 7B, each pixel is marked with a positive sign or a negative sign to indicate the polarity at which the display voltage of each pixel is to be presented during the picture display period of a certain picture.

The pixels shown in Fig. 7B are also specially configured, and such a configuration is also used to solve the aforementioned problem of uneven brightness. As shown in FIG. 7B, such a configuration also causes the polarity of the same row of pixels to alternately positive and negative, thereby making the pixel brightness of the same row uniform.

Through the teachings of the above embodiments, some basic steps of the driving method of the present invention can be summarized, as shown in FIG. FIG. 8 is a flow chart of a driving method of a display panel according to an embodiment of the invention. The display panel has a plurality of pixels and a plurality of data lines. The pixels are arranged in a matrix, and each data line is electrically coupled to a part of the pixels. The driving method includes: dividing the display data to be transmitted by the same data line into a plurality of groups according to chronological order, each group containing display data of N pixels, and displaying data in the same group The display voltages of the corresponding pixels are displayed in the same polarity, and the display data of the adjacent two groups on the same data line causes the display voltages of the corresponding two groups of pixels to exhibit different polarities, and at the same time, the adjacent two data lines are to be transmitted. The display data causes the display voltages corresponding to the two pixels to exhibit different polarities, where N is a natural number and is greater than or equal to 3 (as shown in step S802); and the above pixels are turned on during the display period of the screen, and the above data is transmitted through the above data. The line loads the corresponding display material to the above pixel (as shown in step S804).

Similarly, if a display device uses the driving method of the present invention to drive its display panel, some basic operational behaviors of the internal control circuit of the display device can also be summarized by the teachings of the above embodiments. This will be explained with reference to FIG. Please refer to FIG. 9, which is a schematic diagram of a display device. The display device includes a display panel 910, a data driver 920, a scan driver 930, and a timing controller 940. The display panel 910 has a plurality of pixels (as indicated by the symbol 912), a plurality of data lines (as indicated by the symbol 914), and a plurality of scan lines (as indicated by the numeral 916). The pixels are arranged in a matrix, and each pixel is electrically coupled to one of the scan lines and one of the data lines (the pixel 912 is not shown in the figure, because FIG. 5, FIG. 7A or FIG. The coupling method shown in 7B). The data driver 920 is electrically coupled to the data lines, and the scan driver 930 is electrically coupled to the scan lines. The timing controller 940 is electrically coupled to the data driver 920 and the scan driver 930.

The timing controller 940 is configured to divide the display data to be transmitted by the same data line into a plurality of groups in time sequence, and each group includes display data of N pixels, where N is a natural number and is greater than or equal to 3. The display data in the same group causes the display voltages of the corresponding pixels to exhibit the same polarity, and the display data of the adjacent two groups on the same data line causes the display voltages of the corresponding two groups of pixels to exhibit different polarities, and at the same time. In the middle, the display data to be transmitted by the adjacent two data lines causes the display voltages of the corresponding two pixels to exhibit different polarities. The timing controller 940 is further configured to enable the pixel by using the scan driver 930 during a picture display period, and drive the data line through the data driver 920 to load the corresponding display data into the pixel. The timing controller 940 is configured to control the scan driver 930 to turn on the above pixels column by column during a screen display period.

In summary, the present invention solves the aforementioned problems by driving the display panel by means of N-point inversion, wherein N is a natural number and is greater than or equal to 3. Since N is greater than 2 and less than the total number of pixels in a row, when the display panel is driven by the scanning frequency of 120 Hz and the N-point inversion, the display panel does not have excessive power consumption, and the data The driver will not overheat, and the charging misalignment caused by the delay of the RC signal on the data line and the gate line will also improve. In this way, the disadvantages caused by the conventional method of driving the display panel in a two-point inversion manner are improved. In addition, since N is greater than 2 and less than the total number of pixels in a row, when the display panel is driven by the scanning frequency of 120 Hz and the N-point inversion, the tolerance of the display panel to vertical crosstalk is higher. The display panel when the display panel is driven in a row inversion manner is good for the vertical crosstalk, thereby improving the conventional disadvantages of driving the display panel in a row inversion manner.
