Although the area of the orthographic projection of the first opening area 8 on the plane of the substrate base plate 3 is larger than the area of the orthographic projection of the second opening area 10 on the plane of the substrate base plate 3 in fig. 1, the orthographic projection of the first opening area 8 and the orthographic projection of the second opening area 10 do not overlap with the orthographic projection of the scanning line 4 in the direction perpendicular to the plane of the substrate base plate 3. Certainly, under the condition that the area of the orthogonal projection of the first opening region 8 on the plane of the substrate base plate 3 is ensured to be larger than the area of the orthogonal projection of the second opening region 10 on the plane of the substrate base plate 3, the orthogonal projection of the first opening region 8 overlaps the orthogonal projection of the scan line 4 in the direction perpendicular to the plane of the substrate base plate 3, and the above technical effects can also be achieved, which is not repeated herein, that is, as shown in fig. 2, in some optional embodiments, fig. 2 is another schematic plane structure diagram of a display device provided by the present invention, as can be seen from fig. 2, the density of the second sub-pixels 9 in fig. 2 is larger than the density of the second sub-pixels 9 in fig. 1, that is, the number of the second sub-pixels 9 in fig. 2 per unit area is larger than the number of the second sub-pixels 9 in fig. 1, and the density of the second sub-pixels 9 in fig. 2 is increased, so that the resolution of the second region 6 in fig. 2 is increased, the display has better definition and better display effect. In this embodiment, the display content can be displayed in different regions according to the display requirements of different regions, freely switched, and adjusted in corresponding definition, so that one display panel 1 can display in a variety of ways.

In some alternative embodiments, please refer to fig. 3, fig. 3 is a schematic plan view illustrating another display device according to the present invention; the sub-pixel further includes a non-opening region 11, the non-opening region 11 being disposed around the opening region; the display panel 1 further comprises a black matrix, and the orthographic projection of the black matrix on the plane of the substrate base plate 3 is positioned in the orthographic projection of the non-opening area 11 on the plane of the substrate base plate 3; the black matrices include a first black matrix 12 located at the first region 5 and a second black matrix 13 located at the second region 6; the first black matrix 12 includes a first methyl black matrix 14 extending in the first direction X, and the second black matrix 13 includes a second methyl black matrix 15 extending in the first direction X; the first methyl black matrix 14 is connected with the second methyl black matrix 15; the orthographic projection of the first methyl black matrix 14 and the second methyl black matrix 15 on the plane of the substrate base plate 3 is not overlapped with the orthographic projection of the first opening area 8 and the second opening area 10 on the plane of the substrate base plate 3.

The first black matrix 12 further includes a first ethyl black matrix 16 extending along the first direction X, the second black matrix 13 further includes a second ethyl black matrix 17 extending along the first direction X, and the first ethyl black matrix 16 is connected to the second ethyl black matrix 17; the orthographic projection of the first second black matrix 16 on the plane of the substrate base plate 3 is at least partially overlapped with the orthographic projection of the first opening area 8 on the plane of the substrate base plate 3, and the orthographic projection of the second black matrix 17 on the plane of the substrate base plate 3 is not overlapped with the orthographic projection of the second opening area 10 on the plane of the substrate base plate 3; the width of the first ethyl black matrix 16 along the second direction Y is smaller than the width of the second ethyl black matrix 17 along the second direction Y.

The non-open area 11 disposed around the open area is used for arranging light-tight structures such as traces and electronic components, which need to be shielded from affecting the display effect of the display device 100. Therefore, in this embodiment, a black matrix is provided, an orthogonal projection of the black matrix on the plane of the substrate 3 is located within an orthogonal projection of the non-opening area 11 on the plane of the substrate 3, and the black matrix is used to block the wiring and electronic components in the non-opening area 11. In the present embodiment, a plurality of scanning lines (the scanning lines are covered and not shown in fig. 3) are disposed along the extending direction of the first direction X, in order to prevent the scanning lines from reflecting light, thereby affecting the display effect of the whole display device 100, a first black matrix 14 and a first second black matrix 16 disposed in the first region 5 are used for shielding the scanning lines located in the first region 5, and a second black matrix 15 and a second black matrix 17 disposed in the second region 6 are used for shielding the scanning lines located in the second region 6. Because the area of the orthographic projection of the first opening area 8 on the plane of the substrate base plate 3 is larger than the area of the orthographic projection of the second opening area 10 on the plane of the substrate base plate 3, and because the display panel 1 in the embodiment is a whole panel, and the driving chips for controlling the scanning lines are positioned at the two ends of the display panel 1, part of the scanning lines of the second area 6 can cross part of the first opening area 8, and the part needs to be covered by the first second black matrix 16, but in order to reduce the influence of the first second black matrix 16 on the aperture ratio of the first opening area 8, the width of the first second black matrix 16 along the second direction Y is smaller than the width of the second black matrix 17 along the second direction Y. Of course, the smaller the width of the first ethyl black matrix along the second direction Y, the better, so it is preferable that the orthographic projection of the first ethyl black matrix 16 on the plane of the substrate 3 can be completely overlapped with the orthographic projection of the shielded scanning lines on the plane of the substrate 3.

It is understood that the width of the second methyl black matrix 15 along the second direction Y may be equal to, less than or greater than the width of the first methyl black matrix 14 along the second direction Y, the specific setting is specifically set according to actual needs, and fig. 3 shows a case where the width of the second methyl black matrix 15 along the second direction Y may be equal to the width of the first methyl black matrix 14 along the second direction Y.

Only the case where the width of the second diethyl black matrix 17 in the second direction Y is smaller than the width of the second dimethylblack matrix 15 in the second direction Y is shown in fig. 5. The widths of the second diethyl black matrix 17 and the second dimethyl black matrix 15 in the second direction Y in the present embodiment can be flexibly set as required, and the setting manner is diversified.

In some alternative embodiments, please refer to fig. 6, fig. 6 is a schematic plan view illustrating another display device according to the present invention; the first black matrix 12 further includes a first acrylic black matrix 18 extending in the second direction Y, and the second black matrix 13 further includes a second acrylic black matrix 19 extending in the second direction Y; the display panel 1 further comprises a plurality of data lines 20 extending along the second direction Y, and an orthogonal projection of the data lines 20 on the plane of the substrate base plate 3 is located within an orthogonal projection of the first black matrix 18 or the second black matrix 19 on the plane of the substrate base plate 3.

It can be understood that, in order to prevent the data lines 20 from reflecting light and affecting the display effect of the whole display device 100, a black matrix is further disposed along the second direction Y to block the data lines 20. Therefore, in the embodiment, the first black matrix 18 is disposed in the first region 5 to block the data lines 20 in the first region 5, and the second black matrix 18 is disposed in the second region 6 to block the data lines 20 in the second region 6, so as to ensure the display effect of the display device 100.

It is to be understood that the data line 20 is shown in fig. 6.

In some preferred embodiments, please refer to fig. 7, fig. 7 is a schematic plan view illustrating another display device according to the present invention; in order to ensure the display effect of the display device 100 and prevent the scan lines and the data lines from reflecting, black matrixes are disposed in the first direction X and the second direction Y to shield the scan lines and the data lines.

In some alternative embodiments, please refer to fig. 8, fig. 8 is a schematic plan view illustrating another display device according to the present invention; the first black matrixes 14 and the first second black matrixes 16 are alternately arranged along the second direction Y, and the second black matrixes 15 and the second black matrixes 17 are alternately arranged along the second direction Y; the scanning lines 4 comprise a first scanning line 21 and a second scanning line 22, and the orthographic projection of the first scanning line 21 on the plane of the substrate base plate 3 is positioned in the orthographic projection of the first methyl black matrix 14 and the second methyl black matrix 15 on the plane of the substrate base plate 3; the orthographic projection of the second scanning line 22 on the plane of the substrate base plate 3 is positioned in the orthographic projection of the first black matrix 16 and the second black matrix 17 on the plane of the substrate base plate 3.

It can be understood that, since the first black matrix 14 and the first second black matrix 16 located in the first area 5 are alternately arranged along the second direction Y, and the second black matrix 15 and the second black matrix 17 located in the second area 6 are alternately arranged along the second direction Y, even if the first scan line 21 and the second scan line 22 located under the shielding of the first black matrix 14, the first second black matrix 16, the second black matrix 15, and the second black matrix 17 are also alternately arranged along the second direction Y, the scan lines 4 in this embodiment are regularly arranged along the second direction Y, the manufacturing process is simpler and simpler, the manufacturing time is saved, and the cost is reduced.

It is to be understood that the first scan line 21 and the second scan line 22 are illustrated in fig. 8.

In some alternative embodiments, please refer to fig. 9, fig. 9 is a schematic plan view illustrating another display device according to the present invention; the first sub-pixel 7 and the at least one second sub-pixel 9 located in the same row are connected to the same first scanning line 4.

As can be seen from fig. 9, the first scan line 21 is the scan line 4 shared by the first sub-pixel 7 and the second sub-pixel 9 located in the same row, and the second scan line 22 is connected only to the second sub-pixel 9. On the premise that the density of the second sub-pixels 9 in the second area 6 is greater than the density of the first sub-pixels 7 in the first area 5 and the resolution of the second area 6 is higher than that of the first area 5, the arrangement mode of the scanning lines 4 reduces the number of the scanning lines 4 crossing the first opening area 8, ensures the aperture opening ratio of the first opening area 8, reduces the influence on the display of the first area 5 due to the shielding of the scanning lines 4, ensures the reduction of the required backlight brightness of the first area 5, and ensures the reduction of the power consumption of the whole display device 100.

It is understood that the connection of the data line 4 and the first and second sub-pixels 7 and 9 is only schematic in the figure, and the driving transistor is not shown.

It is understood that the black matrix is not shown in fig. 9 for better understanding.

In some alternative embodiments, please refer to fig. 10 and 11, fig. 10 is a cross-sectional view taken along a-a of fig. 1; FIG. 11 is a top view of the backlight module of FIG. 10; the display device 100 further includes a backlight module 23 disposed opposite to the display panel 1, where the backlight module 23 includes a first backlight source 24, and the first backlight source 24 includes a plurality of LEDs 25 distributed in an array; the first backlight 24 includes a third region 26 and a fourth region 27, the third region 26 corresponding to the first region 5, the fourth region 27 corresponding to the second region 6; the number of LEDs 25 in the third region 26 is smaller than the number of LEDs 25 in the fourth region 27.

In this embodiment, since the aperture ratio of the first region 5 of the display panel 1 is greater than the aperture ratio of the second region 6, the luminance of the first region 5 in the display panel 1 is greater than the luminance of the second region 6, so as to make the display luminance in the whole display panel 1 uniform, and the display effect is better, especially when the display contents of the first region 5 and the second region 6 are required to be the same, the display can be achieved by reducing the backlight luminance in the third region 26 of the backlight module 23. The reduction of the backlight brightness in the third region 26 is achieved by reducing the number of LEDs 25 in the third region 26 in the present embodiment, while more LEDs 25 may be provided in the fourth region 27. The number of the LEDs 25 in the third region 26 is reduced, that is, the number of the LEDs 25 of the whole display device 100 is greatly reduced, so that the power consumption of the display device 100 can be effectively reduced and the manufacturing cost is reduced on the premise of not affecting the display effect.

It is understood that other film structures in the backlight module 23 are not shown in the drawings for more clearly showing the backlight structure, and are not described in detail below.

It can be understood that the display panel 1 further includes a color film substrate 28 disposed opposite to the array substrate 2, a liquid crystal layer 29 located between the color film substrate 28 and the array substrate 2, a first alignment film 30, and a second alignment film 31; the first alignment film 30 is positioned between the liquid crystal layer 29 and the array substrate 2; the second alignment film 31 is located between the liquid crystal layer 29 and the color filter substrate 28, and is not described in detail below.

In some optional embodiments, the display module 100 further includes a backlight module 23 disposed opposite to the display panel 1, where the backlight module 23 includes a first backlight source 24, and the first backlight source 24 includes a plurality of LEDs 25 distributed in an array; the first backlight 24 includes a third region 26 and a fourth region 27, the third region 26 corresponding to the first region 5, and the fourth region 27 corresponding to the second region 6; the current to the LED 25 in the third region 26 is smaller than the current to the LED 25 in the fourth region 27.

Since the display panel 1 in this embodiment is a whole display panel, in order to simplify the manufacturing process, the number of LEDs 25 included in the third region 26 and the fourth region 27 of the first backlight 24 may be the same, thus, during the process of manufacturing the LED 25, the third region 26 and the fourth region 27 can be manufactured in one step in the same process, but since the aperture ratio of the first region 5 corresponding to the third region 26 is greater than the aperture ratio of the second region 6 corresponding to the fourth region 27, when the display panel 1 displays the same contents, in order to secure uniformity of display effect, the current to the LEDs 25 in the third region 26 can be made smaller than the current to the LEDs 25 in the fourth region 27, thereby, the luminous intensity of the LED 25 in the third region 26 is reduced, the display effect of the first region 5 and the second region 6 is ensured to be uniform, the picture quality of the display device 100 is ensured, and the power consumption of the display device 100 is reduced.

Of course, if the number of LEDs 25 in the third region 26 is smaller than the number of LEDs in the fourth region 27, the current to the LEDs 25 in the third region 26 may also be smaller than the current to the LEDs 25 in the fourth region 27 in order to make the luminous intensity of the LEDs 25 in the third region 26 smaller than the luminous intensity of the LEDs 25 in the fourth region 27.

On the premise of not affecting the display effect, the embodiment can effectively reduce the power consumption of the display device 100, and reduce the manufacturing cost.

In some alternative embodiments, please refer to fig. 12 and 13, fig. 12 is a cross-sectional view taken along line B-B of fig. 2; FIG. 13 is a top view of the backlight module of FIG. 12; the display device 100 further includes a backlight module 23 disposed opposite to the display panel 1, the backlight module 23 includes a second backlight source 40, and a light-emitting surface of the second backlight source 40 intersects with a light-emitting surface of the display panel 1; the second backlight source 40 includes a first sub backlight source 32 and a second sub backlight source 33, the first sub backlight source 32 is located on one side of the backlight module 23 close to the first area 5, and the second sub backlight source 33 is located on one side of the backlight module 23 close to the second area 6; the first sub-backlight 32 includes a plurality of LEDs 25, and the second sub-backlight 33 includes a plurality of LEDs 25; the number of LEDs 25 in the first sub-backlight 32 is less than the number of LEDs 25 in the second sub-backlight 33.

For the side-in backlight, when the display contents in the first area 5 and the second area 6 are the same, in order to ensure that the overall display effect of the display panel 1 is uniform, in this embodiment, the first sub-backlight 32 and the second sub-backlight 33 are respectively disposed at two sides of the backlight module 23, and the number of the LEDs 25 in the first sub-backlight 32 is smaller than the number of the LEDs 25 in the second sub-backlight 33, so as to reduce the light emitting intensity of the first sub-backlight 32, thereby reducing the display brightness of the first area 5, ensuring the uniformity of the picture display of the first area 5 and the second area 6, effectively reducing the power consumption of the display device 100, and reducing the manufacturing cost.
