[0002] With the continuous development of science and technology, various display modules have been widely used in people's daily life and work. Among them, the dual-screen display module (i.e. the combination of the display panel and the light control panel) can effectively reduce the cost while improving the display effect compared with the traditional display module, and has great market potential.

[0003] However, since some via holes are provided on the display panel, and the display panel near the via holes is obviously sunken compared with the rest of the display panel, uneven display is likely to occur near the via holes, affecting the display effect. [Summary of the invention]

[Specific implementation method]

[0032] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0033] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0034] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0035] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0036] In the description of this specification, it is necessary to understand that the words such as "substantially", "approximately", "approximately", "about", "roughly", "substantially" and the like described in the claims and embodiments of the present application refer to what can be generally recognized within a reasonable process operation range or tolerance range, rather than an exact value.

[0037] It should be understood that, although the terms first, second, third, etc. may be used to describe the winding portion, sub-portion, etc. in the embodiments of the present application, these winding portions, sub-portions, etc. should not be limited to these terms. These terms are only used to distinguish the winding portion, sub-portion, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first winding portion may also be referred to as the second winding portion, and similarly, the second winding portion may also be referred to as the first winding portion.

[0038] The applicant in this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0039] Figure 1 A schematic diagram of a display module provided in an embodiment of the present application.

[0040] like Figure 1 As shown, the embodiment of the present application provides a display module 00, which includes: a backlight panel 01, a display panel 02, and a light control panel 03. The orthographic projections of any two of the backlight panel 01, the display panel 02, and the light control panel 03 in a direction perpendicular to the surface where the backlight panel 01 is located at least partially overlap, and optionally, the orthographic projections of the display panel 02 and the light control panel 03 in a direction perpendicular to the surface where the backlight panel 01 is located are both located in the area where the backlight panel 01 is located. And the light control panel 03 can be located between the display panel 02 and the backlight panel 01.

[0041] The backlight panel 01 is a structure for providing a light source in the display module 00 , and the light emitted by the backlight panel 01 can be transmitted to the display panel 02 and the light control panel 03 to serve as a light source for both of them to transmit light.

[0042] The display panel 02 is a structure for displaying images in the display module 00, and the display panel 02 includes a plurality of display sub-pixels PA capable of achieving different grayscale brightness. The display panel 02 may include a plurality of display sub-pixels PA of different colors, and the display sub-pixels PA are sub-pixels that can display colors. For example, among the plurality of display sub-pixels PA of different colors in the display module 00, some display sub-pixels PA are red sub-pixels P1, some display sub-pixels PA are green sub-pixels P2, and some display sub-pixels PA are blue sub-pixels P3.

[0043] The light control panel 03 can cooperate with the display panel 02 to more flexibly adjust the display brightness of the display module 00. For example, the light control panel 03 can be located between the display panel 02 and the backlight panel 01 to control the brightness of the light emitted by the backlight panel 01 when it reaches the display panel 02. When the display module 00 is a liquid crystal display module, that is, when the display panel 02 and the light control panel 03 are liquid crystal panels, the backlight panel 01 emits a light beam of uniform brightness to illuminate the light control panel 03 that can realize local dimming. By controlling the deflection angle of the liquid crystal molecules in the light control panel 03 of local dimming, local dimming is realized. The light beam after passing through the light control panel 03 of local dimming is illuminated to the display panel 02 and projects the final image to the viewer, so that the bright area on the display module 00 is bright enough and the dark area is dark enough, thereby greatly improving the visual experience of the display module 00.

[0044] In addition, the light control panel 03 can also control the display module 00 to perform anti-peeping display. For example, after the light emitted from the backlight panel 01 passes through the light control panel 03, the large-angle light emitted from the backlight panel 01 is blocked by the light control panel 03, and these large-angle light cannot reach the display panel 02. The light emitted by the display panel 02 is basically a small-angle light, which makes it impossible for viewers with oblique viewing angles to normally view the picture displayed by the display module 00.

[0045] Figure 2 A schematic diagram of a display sub-pixel including a via area provided in an embodiment of the present application, Figure 3 for Figure 2 A schematic diagram of the partial structure of a cross section along the A1A2 direction.

[0046] like Figure 2 and Figure 3 As shown, at least a portion of the area where the display sub-pixel PA is located includes a via region V, and the via region V includes a first via hole V1.

[0047] Optionally, the area where the partial display sub-pixel P2 is located includes a via area V, and the via area V includes a first via hole V1. For example, the via area V including the first via hole V1 is only located in the area where the specific color display sub-pixel PA is located, and is not located in the area where other color display sub-pixels PA are located. Figure 1As shown, the via area V including the first via hole V1 can be located only in the area where the blue sub-pixel P3 is located, and not in the area where the red sub-pixel P1 and the green sub-pixel P2 are located. Since the visual brightness of the blue sub-pixel P3 is lower than that of the red sub-pixel P1 and the green sub-pixel P2, the via area V is located only in the area where the blue sub-pixel P3 is located, which can reduce the visibility of the via area V on the display module 00, thereby reducing the viewer's attention to the via area V, thereby improving the display effect of the display module 00.

[0048] Optionally, the area where all display sub-pixels PA are located includes a via area V, and the via area V includes a first via hole V1. Since all display sub-pixels PA have via areas V that may cause uneven display in the display module 00, the display quality at different positions in the display panel 02 is the same, and there will be no large differences between different areas.

[0049] like Figure 2 , Figure 3 As shown, the via area V is the area where the first via hole V1 in the display sub-pixel PA is located, or is the first via hole V1 in the display sub-pixel PA and the area around the first via hole V1.

[0050] Alternatively, if Figure 3 As shown, the display panel 02 includes an array substrate 21, and the array substrate 21 includes a substrate S and a plurality of conductive functional film layers and an insulating layer I disposed on the substrate S, wherein the surface of the array substrate 21 away from the substrate S has an obvious depression in the via region V relative to the area outside the via region V. This makes the light emitted by the backlight panel 01 and emitted after passing through the display panel 02 have obvious differences in the via region V and the part outside the via region V, resulting in the problem of uneven display.

[0051] When the display panel 02 is a liquid crystal display module, the display panel 02 includes, in addition to the array substrate 21, an opposing substrate disposed opposite to the array substrate 21 and liquid crystal located between the array substrate 21 and the opposing substrate. If the surface of the array substrate away from the substrate S has an obvious depression in the via region V, the alignment layer AL on the array substrate 21 will be largely gathered in the via region V, causing the thickness of the alignment layer AL to be significantly thinned near the edge of the via region V, and the alignment of the liquid crystal near the via region V is disordered, thereby causing the display brightness of the display panel 02 in the via region V to be significantly different from the display brightness outside the via region V.

[0052] The light control panel 03 includes multiple light control sub-pixels PC, which can control the brightness of the light emitted by the backlight panel 01 when it is transmitted to the display panel 02, that is, the display panel 02 includes multiple areas and the backlight brightness obtained by these areas can be controlled by the light control panel 03. The light control sub-pixels PC are sub-pixels in the light control panel 03 that correspond one-to-one to these areas.

[0053] Optionally, the light control panel 03 can also be a liquid crystal panel, which includes an array substrate. The light control panel 03 also includes an opposing substrate arranged opposite to the array substrate and liquid crystal located between the array substrate and the opposing substrate. The deflection angle of the liquid crystal on the light control panel 03 is controlled to control the brightness of the light control sub-pixel PC, thereby achieving the effect of light control to adjust the display brightness of the display module 00.

[0054] Optionally, the first via hole V1 may be a via hole in the display panel 02 for electrically connecting the touch electrode T with the touch trace TX. Figure 3 As shown, the display panel 02 further includes a touch electrode T, a touch line TX and a data line D; the touch line TX and the data line D are arranged in the same layer, and the touch electrode T is electrically connected to the touch line TX through the conductive structure in the first via hole V1. The touch line TX and the data line D are arranged in the same layer, which can reduce the setting of the metal layer, thereby realizing a thin panel.

[0055] However, the touch line TX and the data line D are arranged on the same layer, resulting in a large distance between the touch line TX and the touch electrode T in a direction perpendicular to the surface of the display panel 02. In order to ensure the contact yield between the touch line TX and the touch electrode T, the first via hole V1 has a large depth and a large width. This results in a significant depression in the via area V relative to the area outside the via area V on the surface of the array substrate 21 away from the substrate S. As a result, the light emitted by the backlight panel 01 and emitted after passing through the display panel 02 has a significant difference in the via area V and the part outside the via area V, resulting in uneven display.

[0056] Figure 4 A schematic diagram of an array substrate provided in an embodiment of the present application.

[0057] like Figure 4 As shown, the display panel 02 is a liquid crystal display panel as an example for explanation, the array substrate 21 includes a substrate S and a data line D, a touch line TX, a pixel electrode P, and a common electrode C arranged on the same side of the substrate S. The common electrode C can be reused as a touch electrode T, and the touch line TX and the data line D can be arranged on the same layer. When the common electrode C is located on the side of the pixel electrode P away from the data line D / touch line TX, the distance between the common electrode C and the touch line TX in the direction perpendicular to the surface where the display module 00 is located is relatively far, resulting in a larger depth of the first via hole V1, a larger area of ​​the via hole region V, and a larger depression depth of the surface of the array substrate away from the substrate S in the via hole region V, which is more likely to cause the above-mentioned technical problems.

[0058] Figure 5 A schematic diagram of a display module provided in an embodiment of the present application.

[0059] like Figure 5As shown, the plurality of light-controlling sub-pixels PC include the first light-controlling sub-pixel PC1, that is, among the plurality of light-controlling sub-pixels PC of the light-controlling panel 03, at least some of the light-controlling sub-pixels PC are the first light-controlling sub-pixels PC1. The orthographic projection of the first light-controlling sub-pixel PC1 on the backlight panel 01 overlaps with the orthographic projection of the display sub-pixel PA including the via area V on the backlight panel 01.

[0060] Alternatively, if Figure 5 As shown, the orthographic projections of a display sub-pixel PA and a plurality of light-controlling sub-pixels PC in a direction perpendicular to the surface where the backlight panel 01 is located overlap, that is, the display brightness of the area where a display sub-pixel PA is located on the display module 00 can be adjusted by a plurality of light-controlling sub-pixels PC, thereby achieving precise adjustment of the display brightness of the display module 00 by the light-controlling sub-pixels PC, thereby improving the display effect of the display module 00.

[0061] When a display sub-pixel PA overlaps with a plurality of light-controlling sub-pixels PC in a direction perpendicular to the surface of the backlight panel 01, only the light-transmitting brightness of the light-controlling sub-pixel PC that overlaps with the orthographic projection of the via area V in a direction perpendicular to the surface of the light-controlling panel 03 can be adjusted. On the one hand, the size of the area where the light-transmitting brightness of the light-controlling sub-pixel PC is adjusted on the display module 00 is reduced, thereby reducing the risk that the observer will easily notice that the light-transmitting brightness around the area where the via area V on the display panel 02 is located is significantly different from that of other areas, thereby improving the display effect. On the other hand, except for the light-controlling sub-pixel PC that overlaps with the via area V, the dimming degree of other light-controlling sub-pixels PC is flexible and controllable, ensuring the display effect and anti-peeping effect of the display module 00.

[0062] Figure 6 A schematic diagram of a display module provided in an embodiment of the present application.

[0063] Alternatively, if Figure 6 As shown, the orthographic projections of a display sub-pixel PA and a light-controlling sub-pixel PC in a direction perpendicular to the surface where the backlight panel 01 is located overlap, that is, the display brightness of the area where a display sub-pixel PA is located on the display module 00 is adjusted by a light-controlling sub-pixel PC, thereby reducing the number of light-controlling sub-pixels PC, thereby saving the cost of the display module 00 and improving the preparation efficiency of the display module 00.

[0064] The light transmittance brightness of at least the area overlapping with the via area V in the first light-controlling sub-pixel PC1 is different from the light transmittance brightness of other light-controlling sub-pixels PC, so as to compensate the brightness of the via area V. For example, when the technical solution of the present application is not adopted and the luminous brightness of the via area V is greater than the brightness of other areas of the display sub-pixel PA, by reducing the brightness of the first light-controlling sub-pixel PC1, the brightness of the via area V in the area perpendicular to the positive projection of the display module 00 is reduced, thereby achieving compensation; or, for example, when the technical solution of the present application is not adopted and the luminous brightness of the via area V is less than the brightness of other areas of the display sub-pixel PA, by increasing the brightness of the first light-controlling sub-pixel PC1, the brightness of the via area V in the area perpendicular to the positive projection of the display module 00 is increased, thereby achieving compensation. Brightness compensation for the first light-controlling sub-pixel PC1 can improve the brightness uniformity of the display module 00, thereby improving the display effect of the display module 00.

[0065] Alternatively, if Figure 5 or Figure 6 As shown, in the embodiment of the present application, when the blue sub-pixel P3 includes the via region V, the first light-controlling sub-pixel PC1 overlaps with the blue sub-pixel P3 and the first region R1 in the first light-controlling sub-pixel PC1 covers the via region V in the blue sub-pixel P3.

[0066] Optionally, the plurality of light-control sub-pixels PC may include the first light-control sub-pixel PC1 and other light-control sub-pixels PC except the first light-control sub-pixel PC1 .

[0067] Optionally, the plurality of light-controlling sub-pixels PC may include only the first light-controlling sub-pixel PC1 but not other light-controlling sub-pixels PC.

[0068] Figure 7 A schematic diagram of a first photon-controlled pixel provided in an embodiment of the present application.

[0069] In some embodiments, Figure 7 As shown, the first light-controlling sub-pixel PC1 includes a first region R1, and the projection of the first region R1 and the via region V overlap in a direction perpendicular to the surface where the display module 00 is located; in the same first light-controlling sub-pixel PC1, the light transmittance brightness of the first region R1 is lower than the light transmittance brightness of the remaining regions in the first light-controlling sub-pixel PC1. Since the first region R1 occupies a smaller area on the display panel 02, and the human eye generally has a weaker observation ability for images with lower brightness, in the same first light-controlling sub-pixel PC1, the light transmittance brightness of the first region R1 is lower, which can reduce the presence of the via region V when the display module 00 is displayed, thereby reducing the viewer's attention to display problems such as uneven display, thereby improving the display effect of the display module 00.

[0070] Alternatively, if Figure 7As shown, the first photo-control sub-pixel PC1 may include the first region R1 and other regions except the first region R1 .

[0071] Optionally, the first photo-control sub-pixel PC1 may include only the first region R1 but not other regions.

[0072] Figure 8 A schematic diagram of a display module provided in an embodiment of the present application.

[0073] In some embodiments, Figure 8 As shown, the light control panel 03 includes a shading structure BM, and the shading structure BM overlaps with the projection of the first region R1 along the direction perpendicular to the surface where the display module 00 is located. When the light emitted by the backlight panel 01 passes through the light control panel 03 and is emitted to the display panel 02, the light of the first region R1 is blocked by the shading structure BM and does not reach the display panel 02. That is, when the viewer views the display module 00, the via area V seen by the viewer is a non-transparent black area, so that the viewer cannot observe the display unevenness problem existing in the display module 00, thereby improving the viewer experience.

[0074] Optionally, along a direction perpendicular to the surface of the display module 00, the signal lines, transistors, etc. in the display module 00 overlap with the light shielding structure BM, so that the viewer cannot see the signal lines, transistors, etc. in the display panel 02 and / or the light control panel 03 when viewing the display module 00, thereby improving the viewing experience of the viewer.

[0075] Optionally, perpendicular to the direction of the surface where the display module 00 is located, the wiring area of ​​the display panel 02 and / or the light control panel 03 overlaps with the shading structure BM, the first area R1 is close to the wiring area, and the shading structure BM overlapping with the first area R1 is connected to the shading structure BM overlapping with the wiring area. Since the orthographic projection area of ​​the first area R1 on the display module 00 is small, such a setting can avoid the shading structure BM overlapping with the first area R1 in the direction perpendicular to the surface where the display module 00 is located from being displayed as a black dot on the display panel 02, thereby improving the visual effect of the viewer, and when manufacturing the shading structure BM, it only needs to be prepared in an integrated manner, thereby improving the manufacturing efficiency of the display module 00.

[0076] Fig. 9 A schematic diagram of a first photocontrol sub-pixel provided in an embodiment of the present application.

[0077] In some embodiments, Fig. 9As shown, the light-controlling sub-pixel PC includes a light-controlling pixel electrode CE, and the light-controlling pixel electrode CE provides an electrical signal for the light-controlling sub-pixel PC, thereby controlling the light-controlling sub-pixel PC to emit light. In the same first light-controlling sub-pixel PC1, the density of the light-controlling pixel electrode CE in the first region R1 is less than the density of the light-controlling pixel electrode CE in other regions. Since in the same first light-controlling sub-pixel PC1, the density of the light-controlling pixel electrode CE in the first region R1 is less than the density of the light-controlling pixel electrode CE in other regions, in the same first light-controlling sub-pixel PC1, the electric field formed between the light-controlling pixel electrode CE in the first region R1 and the common electrode is smaller than the electric field formed between the light-controlling pixel electrode CE in other regions and the common electrode, so that the liquid crystal deflection degree of the first region R1 is smaller, and then the light transmittance brightness of the first region R1 is lower, thereby reducing the presence of the first region R1 when the display module 00 is displayed, thereby reducing the viewer's attention to the display problem such as uneven display, thereby improving the display effect of the display module 00.

[0078] The light-control pixel electrode CE may include a plurality of light-control pixel branch electrodes CX, such as Fig. 9 The vertical light-control pixel branch electrodes CX in the light-control pixel electrode CE include slits between adjacent light-control pixel branch electrodes CX, wherein the density of the light-control pixel electrodes CE specifically refers to the area density of the light-control pixel branch electrodes CX in the light-control pixel electrodes CE.

[0079] It should be noted that the position where the density of the light-controlling pixel branch electrodes CX in the light-controlling pixel electrode CE begins to differ from the density of the light-controlling pixel branch electrodes CX in other regions may be within the first region R1 to avoid affecting the normal display of other regions.

[0080] Optionally, in the same first light-controlling sub-pixel PC1, the spacing between adjacent light-controlling pixel branch electrodes CX in the light-controlling pixel electrode CE in the first region R1 is greater than the spacing between adjacent light-controlling pixel branch electrodes CX in the light-controlling pixel electrode CE in other regions.

[0081] Fig.10 A schematic diagram of a first photon-controlled pixel provided in an embodiment of the present application.

[0082] In a technical solution corresponding to an embodiment of the present application, as Fig.10 As shown, the density of the light-control pixel electrodes CE in the first region R1 is 0. That is, in the same first light-control sub-pixel PC1, the data voltage received by the first region R1 is 0. That is, when the viewer views the display module 00, since the first region R1 only has a common electrode but no light-control pixel electrode CE, the electric field of the first region R1 is 0, so that the liquid crystal in the first region R1 cannot be deflected, and the first region R1 viewed by the viewer is an opaque black region, so that the viewer cannot observe the display unevenness problem existing in the display module 00, thereby improving the viewer experience.

[0083] Optionally, the light-control pixel electrodes CE are deposited on the substrate of the light-control panel 03 , and the light-control pixel electrodes CE in the first region R1 are etched away.

[0084] Fig.11 A schematic diagram of a first photon-controlled pixel provided in an embodiment of the present application.

[0085] In some embodiments, Fig.11 As shown, the light-controlling sub-pixel PC includes a light-controlling pixel electrode CE, and the light-controlling pixel electrode CE includes a plurality of light-controlling pixel branch electrodes CX. In the same first light-controlling sub-pixel PC1, the extension direction of at least part of the plurality of light-controlling pixel branch electrodes CX located in the first region R1 is different from the extension direction of part of the light-controlling pixel branch electrodes CX located in other regions.

[0086] The extension direction of the light-control pixel branch electrode CX in the first region R1 is different from that in other regions, so that the brightness of the light-control sub-pixel PC in the first region R1 is different from that in other regions. For example, when the light-control panel 03 is a liquid crystal display module, and the liquid crystal display module includes an array substrate, an opposing substrate arranged opposite to the array substrate, and a liquid crystal located between the array substrate and the opposing substrate. In the same light-control sub-pixel PC, the deflection direction of the liquid crystal in the region where the extension direction of the light-control pixel branch electrode CX changes is disordered, resulting in the region where the extension direction changes cannot be displayed normally. Since the light-control pixel branch electrode CX in the first region R1 has a different extension direction from that in other regions, the light-control sub-pixel PC in the first region R1 appears dark, thereby reducing the viewer's attention, making it difficult for the viewer to notice the display unevenness problem existing in the display module 00, thereby improving the viewing experience.

[0088] Alternatively, if Fig.12 As shown, in the same first light-control sub-pixel PC1, the extension direction of at least part of the plurality of light-control pixel branch electrodes CX located in the first region R1 is different from the extension direction of the part of the light-control pixel branch electrodes CX located in other regions, and at least two light-control pixel branch electrodes CX have different extension directions in the first region R1, which further aggravates the degree of disorder in the deflection direction of the liquid crystal in the region where the extension direction changes, thereby further reducing the brightness of the region where the extension direction changes, further reducing the viewer's attention, and further improving the viewing experience.

[0090] Alternatively, if Fig.13 As shown, in the same first light-controlling sub-pixel PC1, at least part of the extension direction of the plurality of light-controlling pixel branch electrodes CX located in the first region R1 is different from the extension direction of the part of the light-controlling pixel branch electrodes CX located in other regions, and any two light-controlling pixel branch electrodes CX have different extension directions.

[0091] Fig.14 Schematic diagram of the black domain area in the embodiment of the present application.

[0092] In some embodiments, Figure 11-13 As shown, in the first light control sub-pixel PC1, the portion where the plurality of light control pixel branch electrodes CX are located in the first region R1 includes a corner. Fig.14 As shown, the area where the corner is located cannot be displayed normally due to the disordered deflection direction of the liquid crystal, and usually appears as a black domain area. The appearance of the black domain area in the display module 00 can effectively reduce the brightness.

[0093] Alternatively, if Fig.11 As shown, in the first light-controlling sub-pixel PC1 , portions of the plurality of light-controlling pixel branch electrodes CX located in the first region R1 include corners, and the corner directions of at least two light-controlling pixel branch electrodes CX are different.

[0094] Alternatively, if Fig.12 As shown, in the first light-controlling sub-pixel PC1 , portions of the plurality of light-controlling pixel branch electrodes CX located in the first region R1 include corners, and the corner directions of any two light-controlling pixel branch electrodes CX are different.

[0095] Alternatively, if Fig.13 As shown, in the first light-controlling sub-pixel PC1 , portions of the plurality of light-controlling pixel branch electrodes CX located in the first region R1 include corners, and a portion of at least one light-controlling pixel branch electrode CX located in the first region R1 includes a plurality of corners.

[0096] Alternatively, if Fig.13 As shown, in the first light-control sub-pixel PC1, portions of multiple light-control pixel branch electrodes CX located in the first region R1 include corners, and a portion of at least one light-control pixel branch electrode CX located in the first region R1 includes multiple corners, and in the same light-control pixel branch electrode CX including multiple corners, at least two corners are in different directions.

[0097] It should be noted that the arrangement of the portion of the multiple light-control pixel branch electrodes CX in the first light-control sub-pixel PC1 located in the first region R1 is not limited to the scenario given in the above-mentioned embodiment, and the arrangement of the portion of the light-control pixel branch electrode CX located in the first region R1 may also be in other forms, as long as its arrangement can reduce the light transmittance brightness in the first region R1, it is within the scope of protection of the present application.

[0098] Fig.15 A schematic diagram of a display module provided in an embodiment of the present application.

[0099] In some embodiments, Fig.15 As shown, the plurality of light-controlling sub-pixels PC also include a second light-controlling sub-pixel PC2 , and the display sub-pixel PA including the via area V overlaps with the orthographic projections of the first light-controlling sub-pixel PC1 and the second light-controlling sub-pixel PC2 on the backlight panel 01 .

[0100] Fig.16 A schematic diagram of a photon-controlled pixel provided in an embodiment of the present application.

[0101] like Fig.16 As shown, the first light-controlling sub-pixel PC1 includes a first light-controlling pixel electrode E1, and the second light-controlling sub-pixel PC2 includes a second light-controlling pixel electrode E2. Optionally, the first light-controlling pixel electrode E1 and the second light-controlling pixel electrode E2 are both independently controllable.

[0102] The first light-controlling pixel electrode E1 overlaps with the first region R1 along a direction perpendicular to the surface where the display module 00 is located, and the second light-controlling pixel electrode E2 does not overlap with the first region R1 along a direction perpendicular to the surface where the display module 00 is located. That is, in the same first light-controlling pixel PC1, the first light-controlling pixel electrode E1 controls the sub-pixel of the first region R1 to emit light, and the second light-controlling pixel electrode E2 does not control the sub-pixel of the first region R1 to emit light.

[0103] In at least part of the display mode of the display module 00, in the same first light-control sub-pixel PC1, the data voltage received by the first light-control pixel electrode E1 is different from the data voltage received by the second light-control pixel electrode E2. Thus, the brightness compensation is performed on the first region R1. For example, when the luminous brightness of the via region V is greater than the brightness of other regions of the display sub-pixel PA, the brightness of the via region V is reduced by reducing the brightness of the first region R1, thereby achieving compensation; or, for example, when the luminous brightness of the via region V is less than the brightness of other regions of the display sub-pixel PA, the brightness of the via region V is increased by increasing the brightness of the first region R1, thereby achieving compensation. Performing brightness compensation on the first region R1 can improve the brightness uniformity of the display module 00, thereby improving the display effect of the display module 00.

[0104] Optionally, the display module 00 includes a daily mode and an eye protection mode. In the daily mode, in the same first light-control sub-pixel PC1, the data voltage received by the first light-control pixel electrode E1 is the same as the data voltage received by the second light-control pixel electrode E2; in the eye protection mode, in the same first light-control sub-pixel PC1, the data voltage received by the first light-control pixel electrode E1 is different from the data voltage received by the second light-control pixel electrode E2.

[0105] Optionally, the display panel 02 is a liquid crystal display module, and the liquid crystal display module includes an array substrate, an opposing substrate arranged opposite to the array substrate, and a liquid crystal located between the array substrate and the opposing substrate, and the display panel 02 includes positive liquid crystal; the positive liquid crystal 00 is a liquid crystal whose deflection angle is larger when the data voltage is larger, and the brightness of the display module 00 is larger. In at least a part of the display mode of the display module 00, in the same first light-control sub-pixel PC1, the data voltage received by the first light-control pixel electrode E1 is greater than the data voltage received by the second light-control pixel electrode E2. Since the surface of the array substrate away from the substrate S has an obvious depression in the via area V relative to the area outside the via area V, and the liquid crystal is a positive liquid crystal, this makes the light emitted by the backlight plate 01 and emitted after passing through the display panel 02 darker in the via area V than in the part outside the via area V. Therefore, the data voltage received by the first light-control pixel electrode E1 is greater than the data voltage received by the second light-control pixel electrode E2, and the brightness of the via area V can be compensated, that is, the brightness of the via area V is improved, thereby achieving compensation.

[0106] Optionally, the display panel 02 is a liquid crystal display module, and the liquid crystal display module includes an array substrate, an opposing substrate arranged opposite to the array substrate, and a liquid crystal located between the array substrate and the opposing substrate, and the display panel 02 includes negative liquid crystal; the negative liquid crystal is a liquid crystal whose deflection angle is smaller when the data voltage is larger, and the brightness of the display module 00 is smaller. In at least a part of the display mode of the display module 00, in the same first light-control sub-pixel PC1, the data voltage received by the first light-control pixel electrode E1 is smaller than the data voltage received by the second light-control pixel electrode E2. Since the surface of the array substrate away from the substrate S has an obvious depression in the via area V relative to the area outside the via area V, and the liquid crystal is a negative liquid crystal, this makes the light emitted by the backlight plate 01 and emitted after passing through the display panel 02 brighter in the via area V than in the part outside the via area V. For this reason, the data voltage received by the first light-control pixel electrode E1 is smaller than the data voltage received by the second light-control pixel electrode E2, and the brightness of the via area V can be compensated, that is, the brightness of the via area V is reduced, thereby achieving compensation.

[0107] Fig.17 A schematic diagram of a display module provided in an embodiment of the present application.

[0108] In some embodiments, Fig.17 As shown, the orthographic projection of the display sub-pixel PA excluding the via area V on the backlight panel 01 overlaps with the orthographic projection of the light-control sub-pixel PC on the backlight panel 01 in a one-to-one correspondence, so that the light-control sub-pixel PC overlapping with the orthographic projection of the display sub-pixel PA excluding the via area V on the backlight panel 01 only receives the electrical signal of one light-control pixel electrode CE, so that the display brightness of these light-control sub-pixels PC is uniform, thereby improving the visual effect of the display module 00 and reducing the number of wirings.

[0109] Alternatively, if Fig.17 As shown, the orthographic projection of the display sub-pixel PA excluding the via area V on the backlight panel 01 overlaps with the orthographic projection of the light-control sub-pixel PC on the backlight panel 01 in a one-to-one correspondence, and the orthographic projection of the display sub-pixel PA including the via area V on the backlight panel 01 overlaps with a first light-control pixel PC1 and multiple second light-control pixels PC2.

[0110] In some embodiments, Figure 5 , Figure 6 , Figure 8 , Fig.15 As shown, along the direction perpendicular to the surface of the display module 00, the number of light-controlling sub-pixels PC overlapping with the display sub-pixels PA not including the via region V is equal to the number of light-controlling sub-pixels PC overlapping with the display sub-pixels PA including the via region V. The display brightness of each area overlapping with the light-controlling sub-pixel PC in the display sub-pixel PA not including the via region V can be accurately controlled, so that the display module 00 presents richer colors, thereby improving the display effect of the display module 00.

[0112] like Fig.18 As shown, the embodiment of the present application further provides a display device, including a touch substrate 00 provided in any of the above embodiments. Exemplarily, the display device can be an electronic device such as a mobile phone, a computer, a smart wearable device (e.g., a smart watch), and a vehicle-mounted display device, which is not limited in the embodiment of the present invention.

[0113] In the display device provided by the present application, in an embodiment of the present application, a first light-controlling sub-pixel PC1 is arranged on the light-controlling panel 03, and the first light-controlling pixel PC1 includes a first area R1, and the first area R1 overlaps with the projection of the via area V in a direction perpendicular to the surface where the display module 00 is located, and in the same first light-controlling sub-pixel PC1, the light transmittance brightness of the first area R1 is different from the light transmittance brightness of the remaining areas, thereby performing brightness compensation on the first area R1, so that the brightness of the display module 00 is uniform, thereby improving the display effect of the display module 00.

[0114] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
