[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0036] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0037] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual proportions, and are only intended to illustrate the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0038] The present disclosure provides a display panel. Figure 1 , Figure 2 , Figure 3 As shown, the display panel 2 includes: a plurality of pixels 3 arranged in an array; each pixel 3 includes a plurality of sub-pixels 4; the plurality of pixels 3 arranged in an array include: a plurality of pixel rows 32; each pixel row 32 includes: a plurality of sub-pixels 4 arranged along a first direction X, and the plurality of pixel rows 32 extend along a second direction Y; the first direction X intersects with the second direction Y;

[0039] The display panel 2 specifically includes: a first array substrate 5 and a first opposing substrate 6 that are arranged opposite to each other, and a first liquid crystal layer 7 located between the first array substrate 5 and the first opposing substrate 6; the first array substrate includes: a plurality of first driving transistors 8 arranged in an array; at least one pixel 3 is spaced between two adjacent first driving transistors 8 in a first direction X; the first opposing substrate includes: a plurality of shading portions 9 corresponding one to one to the first driving transistors 8; the orthographic projection of the shading portion 9 on the plane where the first array substrate 5 is located only covers the orthographic projection of the first driving transistor 8 on the plane where the first array substrate 5 is located.

[0040] It should be noted that in the related art, the shading area in the opposite substrate of the display panel is a grid-like pattern, and the grid opening area is a light-transmitting area, so the light transmittance of the display panel is low. Therefore, when the display panel is applied to a display product including a double-layer display panel, the light transmittance of the display product is low. Moreover, in the related art, the sub-pixel units in the two display panels in the display product of the double-layer display panel correspond one to one, which further leads to the low light transmittance of the double panel. Since the light transmittance of the double panel is low, a higher backlight brightness is required. In this way, the operating temperature of the display product is high, which is prone to brightness attenuation and color coordinate shift problems. When testing the display product, when the color coordinate shift of the display product occurs, it is considered that the color coordinate of the display product does not meet the specified range of the color coordinate and needs to be scrapped, affecting the display product manufacturing yield.

[0041] The display panel provided by the embodiment of the present disclosure includes at least one pixel between two adjacent first driving transistors in the first direction, and the number of the first driving transistors is much smaller than the number of sub-pixel units. The first driving transistor corresponds to the control unit of the display panel, which is equivalent to reducing the number of control units without changing the total area of ​​the display panel, thereby improving the light transmittance of the display panel. In addition, the first opposing substrate includes a plurality of shading portions, and the shading portions only cover the area where the first driving transistor is located, that is, compared with the shading area in the first opposing substrate in the related art being a grid-shaped pattern, the plurality of shading portions in the display panel of the present disclosure are arranged in an array, which can reduce the area of ​​the shading area in the first opposing substrate, thereby improving the light transmittance of the display panel. In this way, when the display panel provided by the embodiment of the present disclosure is applied to a display product of a double-layer display panel, the light transmittance of the display product can be improved, the display effect can be improved, and the user experience can be enhanced. The light transmittance of the display panel is improved, so the required backlight brightness can also be reduced, thereby reducing the operating temperature of the display product and avoiding the problem of brightness attenuation and color coordinate shift caused by high temperature. Improve the production yield of display products.

[0042] It should be noted that Figure 2 In the figure, dotted lines are used to illustrate the area covered by the orthographic projection of the light shielding portion 9 on the first array substrate.

[0043] It should be noted that Figure 2 , Figure 3 The first direction X and the second direction Y are perpendicular.

[0044] In some embodiments, Figure 2 As shown, the first array substrate further includes: a plurality of first data lines 16 and a plurality of first scan lines 17 that are arranged to cross each other.

[0045] In some embodiments, Figure 2As shown, each first scan line 17 extends along a first direction X, and each first data line 16 extends along a second direction Y.

[0046] In some embodiments, the first driving transistor may be, for example, a thin film transistor. Figure 2 As shown, the first driving transistor includes: a gate G, a source S, a drain D and an active layer 19. The gate G is disposed in the same layer and electrically connected to the first scan line 17. The source S is disposed in the same layer and electrically connected to the first data line 16. In a specific implementation, the first scan line is located on the side of the first data line facing the substrate, and the active layer is, for example, located between the gate and the source and drain, that is, the thin film transistor is a bottom gate structure.

[0047] In some embodiments, Figure 2 As shown, the display panel includes a plurality of light control units 18 arranged in an array. That is, a plurality of first scanning lines and a plurality of first data lines are divided into a plurality of light control units by crossing horizontally and vertically. The number of light control units corresponds to the number of first driving transistors.

[0048] In some embodiments, Figure 4 , Figure 5 As shown, the first array substrate further includes: a planar first common electrode 23 located on the side of the first driving transistor 8 facing the first counter substrate 6; the first common electrode 23 includes a light-transmitting material.

[0049] It should be noted that Figure 4 For example, it can be along Figure 2 The cross-sectional view of AA', Figure 5 For example, it can be along Figure 2 Cross-sectional view of BB'. Figure 2 The first common electrode is not shown.

[0050] In the display panel provided by the embodiment of the present disclosure, the first common electrode is a planar electrode, and the material of the first common electrode is a light-transmitting material, thereby further improving the aperture ratio of the light control unit of the first display panel and improving the light transmittance of the display panel.

[0051] In some embodiments, Figure 4 , Figure 5 As shown, each light control unit of the first array substrate further includes a first pixel electrode 24. The first pixel electrode 24 is located on a side of the first common electrode 23 away from the first driving transistor 8.

[0052] In some embodiments, Figure 4 , Figure 5As shown, the first array substrate 5 further includes: a first base substrate 29 on the side of the gate G away from the drain D, a gate insulating layer 25 between the gate G and the drain D, a first insulating layer 26 between the drain D and the first common electrode 23, a second insulating layer 27 between the first common electrode 23 and the first pixel electrode 24, and a third insulating layer 28 between the first pixel electrode 24 and the first liquid crystal layer 7. The first pixel electrode 24 is electrically connected to the drain D through a via hole penetrating the second insulating layer 27 and the first insulating layer 26.

[0053] It should be noted that, except for the region where the first pixel electrode is electrically connected to the drain electrode, the first common electrode is integrally connected to form a planar electrode.

[0054] In some embodiments, Figure 4 , Figure 5 As shown, the first counter substrate 6 further includes a second base substrate 30. The light shielding portion 9 is located on the side of the second base substrate 30 facing the first liquid crystal layer 7. The first counter substrate 6 further includes a protective layer 31 located on the side of the light shielding portion 9 away from the second base substrate 30.

[0055] In some embodiments, the first array substrate further includes:

[0056] A plurality of first common voltage signal lines are electrically connected to the first common electrode and are arranged in the same layer as the gate of the first driving transistor.

[0057] In a specific implementation, the extension direction of the first common voltage signal line can be set to be the same as the extension direction of the first scan line. A plurality of first common voltage signal lines and a plurality of first scan lines are arranged adjacent to each other in a one-to-one correspondence.

[0058] In some embodiments, n pixels are spaced between two adjacent first driving transistors in the first direction, wherein n is the least common multiple of the number of driving transistors and the number of pixel units.

[0059] That is, in some embodiments, each light control unit corresponds to n pixels.

[0060] In some embodiments, Figure 2 As shown, each light control unit 18 corresponds to a pixel 3 .

[0061] In some embodiments, Figure 1 , Figure 2 As shown, each pixel 3 includes three sub-pixels 4.

[0062] In some embodiments, the sub-pixels in each pixel are different colors.

[0063] In specific implementation, Figure 2As shown, each pixel 4 includes a red sub-pixel R, a blue sub-pixel B and a green sub-pixel G, for example.

[0064] Of course, in some embodiments, each pixel may also include four sub-pixels or more sub-pixels. When each pixel includes four sub-pixels, for example, it includes: a red sub-pixel, a blue sub-pixel, a green sub-pixel, and a white sub-pixel.

[0065] In some embodiments, each light control unit may also correspond to multiple pixels. Figure 6 As shown, each light control unit 18 corresponds to four pixels 3 .

[0066] In some embodiments, the colors of the multiple sub-pixels in each pixel are the same, that is, the display panel is used to achieve grayscale adjustment.

[0067] In some embodiments, Figure 3 As shown, the orthographic projection shape of the light shielding portion on the first array substrate is a rectangle with chamfered corners.

[0068] In this way, the orthographic projection area of ​​the light shielding portion on the first array substrate can be reduced as much as possible while shielding the first driving transistor, thereby improving the light transmittance of the first display panel and the light transmittance of the display panel.

[0069] Of course, the orthographic projection of the light shielding portion on the first array substrate may also be other shapes, such as a circle, a rectangle, or other polygons.

[0070] In some embodiments, a length h1 of the rectangle in the first direction X is greater than or equal to 30 micrometers and less than or equal to 180 micrometers; a width h2 of the rectangle in the second direction Y is greater than or equal to 30 micrometers and less than or equal to 180 micrometers.

[0071] In a specific implementation, the size of the light shielding portion can be actually selected according to the size of the first driving transistor, so that the light shielding portion covers the first driving transistor.

[0072] In some embodiments, a length h1 of the rectangle in the first direction X is 91.5 micrometers, and a width h2 of the rectangle in the second direction Y is 66 micrometers.

[0073] In some embodiments, an angle between the chamfer and the first direction or the second direction is greater than 0° and less than or equal to 70°.

[0074] In some embodiments, a length h3 of the chamfer in the first direction X is greater than 0 micrometer and less than or equal to 30 micrometers; a width h4 of the chamfer in the second direction Y is greater than 0 micrometer and less than or equal to 30 micrometers.

[0075] Based on the same inventive concept, the embodiment of the present disclosure also provides a display device, such as Figure 7 As shown, including:

[0076] The above-mentioned display panel 2 provided in the embodiment of the present disclosure;

[0077] The second display panel 1 is located at the light emitting side of the display panel 2 .

[0078] In a specific implementation, the display panel 2 may be used as a light control panel, for example. For the sake of distinction, the display panel 2 is referred to as a first display panel in the following description.

[0079] In some embodiments, Figure 7 As shown, the second display panel includes: a plurality of pixels 3 arranged in an array; each pixel 3 includes a plurality of sub-pixels 4;

[0080] The second display panel specifically includes: a second array substrate 10 and a second counter substrate 11 which are arranged opposite to each other, and a second liquid crystal layer 12 located between the second array substrate 10 and the second counter substrate 11; Figure 1 , Figure 8 As shown, the second counter substrate includes: a shading layer 13; the shading layer 13 includes an opening area 14 corresponding one-to-one to the sub-pixels 4 of the second display panel, and a shading area 15 outside the opening area 14; the orthographic projection of the shading portion on the shading layer falls into the shading area 15.

[0081] In the display device provided by the embodiment of the present disclosure, the shading portion of the first display panel is arranged in the area covered by the shading area of ​​the second display panel, thereby further reducing the light transmittance after the first display panel and the second display panel overlap, further improving the light transmittance of the display device, improving the display effect, and enhancing the user experience.

[0082] In some embodiments, the orthographic projections of the first data line and the first scan line on the light shielding layer fall into the light shielding area.

[0083] In the display device provided by the embodiment of the present disclosure, the first data line and the first scan line of the first display panel are arranged in the area covered by the shading area of ​​the second display panel, so as to further reduce the light transmittance after the first display panel and the second display panel overlap, further improve the light transmittance of the display device, improve the display effect, and enhance the user experience.

[0084] In some embodiments, the orthographic projection of the first common voltage signal line on the light shielding layer falls within the light shielding area.

[0085] In some embodiments, Fig. 9 , Fig.10 As shown, the second array substrate includes: a second data line 20 , a second scan line 21 and a second driving transistor 22 .

[0086] In a specific implementation, the second driving transistor includes: a gate, a source, a drain and an active layer. The gate of the second driving transistor is arranged in the same layer as the second scanning line and is electrically connected. The source of the second driving transistor is arranged in the same layer as the second data line and is electrically connected. In a specific implementation, the second array substrate also includes: a second pixel electrode and a second common electrode.

[0087] It should be noted that in the display device provided by the embodiment of the present disclosure, the second display panel and the first display panel are both liquid crystal panels. That is, the display device includes a double-layer liquid crystal panel. Among them, the first display panel includes a plurality of light control units, so that each light control unit can control the brightness and darkness independently, which can make the picture displayed by the display device more delicate, so as to improve the display effect. In a specific implementation, the first opposing substrate of the first display panel does not need to be provided with a color filter. The second opposing substrate of the second display panel needs to be provided with a color filter. In a specific implementation, in the second opposing substrate of the second display panel, the color filter is provided in the light-transmitting area of ​​the light-shielding layer.

[0088] It should be noted that Fig. 9 An example is given in which one light control unit of the first display panel corresponds to one pixel of the second display panel.

[0091] It should be noted that in the related art, the bending directions of the data lines of the two liquid crystal panels are different, and the shading area of ​​the opposite substrate of the first display panel needs to cover the data lines of the first display panel.

[0092] In the display device provided by the embodiment of the present disclosure, the bending direction of the first data line corresponding to each light control unit toward the light control unit is the same as the bending direction of the second data line corresponding to each sub-pixel unit toward the sub-pixel unit, so that the first data line in the first display panel is conveniently arranged within the light shielding area coverage of the liquid crystal panel, and the first data line can be prevented from affecting the light transmittance of the second display panel. Thus, the transmittance of the display device including two layers of liquid crystal panels can be improved.

[0093] In some embodiments, the display device further includes: a backlight module located on a side of the first display panel away from the second display panel.

[0094] Next, an example is given to illustrate that the display device provided by the embodiment of the present disclosure can improve the light transmittance.

Compared with the related art, the light transmittance of the first display panel can be greatly improved. The aperture ratio of the panel after the first display panel and the second display panel are bonded can be increased to 52.5% to 56.7%. Compared with the related art, the light transmittance of the bonded panel provided by the embodiment of the present disclosure can be increased by 60%.

[0097] In summary, the display panel and display device provided by the embodiments of the present disclosure include a plurality of shading portions in the first facing substrate of the first display panel, and the shading portions only cover the area where the first driving transistor is located, that is, compared with the shading area in the first facing substrate in the related art being a grid-like pattern, the plurality of shading portions in the first display panel of the present disclosure are arranged in an array, which can reduce the area of ​​the shading area in the first facing substrate, thereby improving the light transmittance of the first display panel and the light transmittance of the display device. Improve the display effect and enhance the user experience. The light transmittance of the display device is improved, so the required backlight brightness can also be reduced, thereby reducing the operating temperature of the display product and avoiding the problems of brightness attenuation and color coordinate shift caused by high temperature.
