[0031] 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.

[0032] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0036] It should be understood that although the terms first, second, etc. may be used in the embodiments of the present application to describe the display panel, pixel, wiring area, light-emitting device, etc., these should not be limited to these terms. These terms are only used to distinguish the display panel, pixel, wiring area, light-emitting device, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first light-emitting device may also be referred to as the second light-emitting device, and similarly, the second light-emitting device may also be referred to as the first light-emitting device. The applicant of this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0037] Figure 1 A schematic plan view of a display module provided in an embodiment of the present application, Figure 2 A method provided in the embodiment of the present application Figure 1 A schematic cross-sectional view along the P-P' direction.

[0038] The present application embodiment provides a display module 100, combined with Figure 1 , Figure 2As shown, the display module 100 includes a first display panel A100, and the first display panel A100 includes a transparent area A10. The display module 100 also includes a second display panel B100, and the second display panel B100 includes a retaining wall B10 and a first pixel B20, and the retaining wall B10 at least partially surrounds the first pixel B20, and the second display panel B100 is located on one side of the backlight surface of the first display panel A100.

[0039] In the related art, a device in which a display module includes a plurality of display panels arranged in a superimposed manner perpendicular to the surface where the display module is located can be applied to fields such as vehicle-mounted display. In some applications, a second display panel located below can be used to display a background pattern consistent with a frame pattern, so that the display device can form an integrated visual effect with the background. The first display panel located above is used to display the working screen. The first display panel includes a transparent area, and the background pattern can be displayed through the transparent area. However, due to the inconsistency of the size and pixel arrangement of the first display panel and the second display panel, the display of the second display panel by the first display panel will be blocked, affecting the display effect.

[0040] In order to improve the display effect of the display module 100 , the inventor of the present application proposed the following technical solution.

[0041] In the direction perpendicular to the plane where the display module 100 is located, the first pixel B20 at least partially overlaps with the transparent area A10, and the retaining wall B10 at least partially does not overlap with the transparent area A10. It can be seen from the related technologies introduced in the above content that the display on the second display panel B100 is obtained by reflecting light from multiple first pixels B10, and the light reflected by the first pixel B20 on the second display panel B100 needs to be emitted through the transparent area A10 on the first display panel A100. Then, in the direction perpendicular to the plane where the display module 100 is located, the first pixels B10 included in the overlapping part of the first display panel A100 and the second display panel B100 all have corresponding transparent areas A20, and the first pixel B10 at least partially overlaps with the transparent area A10 to realize the light output display of the first pixel B20.

[0042] The retaining wall B10 located on the second display panel B100 can define a plurality of first pixels B20. Generally, when the second display panel B100 is displaying, part of the retaining wall B10 does not have a content display effect. In a direction perpendicular to the plane where the display module 100 is located, the retaining wall B10 is set to at least partially not overlap with the transparent area A10, which is conducive to making the transparent area A10 overlap with the first pixel B20 that can reflect light as much as possible, thereby increasing the area of ​​the first pixel B20 reflecting light from the transparent area A10.

[0043] In the embodiment of the present application, the first pixel B20 is at least partially overlapped with the transparent area A10 in the direction perpendicular to the plane where the display module is located, and the retaining wall B10 located on the second display panel B100 at least partially does not overlap with the transparent area A10, and the transparent area A10 is used to allow the first pixel B20 to smoothly reflect light toward the light-emitting surface of the display module 100. Further, the embodiment of the present application is conducive to ensuring that most of the light reflected by the first pixel B10 can be emitted outside the display module 100, thereby improving the display effect of the display module 100. In addition, the present solution is beneficial for more scientifically setting the device positions in the first display panel A100 and the second display panel B100 through the position correspondence between the transparent area A10 and the blocking wall B10 and the first pixel B20, so that the alignment preparation of the first display panel A100 and the second display panel B100 is more regular, thereby avoiding the situation where the devices on the first display panel A100 and the second display panel B100 are messyly aligned and thus affect each other's light output; thereby, the first display panel A100 can emit light normally, and the second display panel B100 located therebelow can also reflect more light toward the light-emitting surface of the display module 100, thereby improving the display effect of the display module 100.

[0044] In one embodiment of the present application, continue to refer to Figure 1 , Figure 2 As shown, the first display panel A100 also includes a plurality of light-emitting devices A20. In a direction perpendicular to the plane where the display module 100 is located, the retaining wall B10 and the light-emitting devices A20 at least partially overlap. The plurality of light-emitting devices A20 located on the first display panel A100 are used to complete the display work of the first display panel A100. On the first display panel A100, the position where the light-emitting devices A20 are located is a non-transparent area.

[0045] In the embodiment of the present application, a baffle wall B10 located on the second display panel B100 is arranged to at least partially overlap with the light-emitting device A20 located on the first display panel A100. Since in some cases the area where the baffle wall B10 is located does not emit light, the baffle wall B10 and the light-emitting device A20 are at least partially overlapped, which helps to significantly reduce the overlapping area of ​​the baffle wall B10 and the transparent area A10, thereby increasing the overlapping area of ​​the first pixel B20 and the transparent area A10.

[0046] In one embodiment of the present application, continue to refer to Figure 1 , Figure 2 As shown, a plurality of light emitting devices A20 in the first display panel A100 are arranged along a first direction X1, and the light emitting devices A20 and the transparent areas A10 are alternately arranged along a second direction X2. The first direction X1 intersects with the second direction X2 and is parallel to the direction of the plane where the display module 100 is located.

[0047] For example, Figure 1 As shown, the first pixel B20 on the second display panel B100 is set as a square pixel, and the first pixel B20 is arranged in an array on the second display panel B100. The light-emitting devices A20 on the first display panel A100 are arranged along the first direction X1, and the transparent area A10 is located between two adjacent light-emitting devices A20 in the second direction X2. A transparent space is reserved between two adjacent light-emitting devices A10 so that the reflected light of the first pixel B10 can be emitted more outside the display module 100.

[0048] It should be noted that the preparation position of the first pixel B20 on the second display panel B100 provided in the embodiment of the present application is only an example, including but not limited to this preparation position. The preparation position of the light-emitting device A20 on the first display panel A100 provided in the embodiment of the present application is only an example, including but not limited to this preparation position.

[0049] In the embodiment of the present application, a plurality of light-emitting devices A20 on the first display panel A100 are arranged in a regular pattern with the transparent area A10, which is beneficial for setting the device position on the second display panel B100 according to the device position of the first display panel A100, increasing the alignment between the first display panel A100 and the second display panel B100, and improving the alignment between the first pixel B20 and the transparent area A10, thereby increasing the light emitting effect of the first pixel B20.

[0050] Figure 3 Another embodiment provided in this application Figure 1 Schematic diagram of the cross section along the P-P' direction.

[0051] In one embodiment of the present application, Figure 3As shown, the first display panel A100 also includes a first routing area A30, which is arranged in the second direction X2 and extends in the first direction X1. The routing lines distributed in the first routing area A30 in the first display panel A100 can be a variety of different routing lines extending along the first direction X1. For example, the first routing area A30 can include a selection signal line, such as a scanning signal line, a light-emitting control signal line, etc., or a reference voltage line, etc. At least part of the routing lines located in the first routing area A30 provides a signal for the pixel circuit, thereby driving the light-emitting device A20 to emit light. When the routing lines in the first routing area A30 are non-transparent metal routing lines, since the metal will reflect light, it is easy to interfere with the display of the first display panel A100 and affect its display effect. Therefore, a light-shielding layer, such as BM (Black Matrix), is usually prepared above the metal material (i.e., closer to the light-emitting surface) to avoid interference from external light. Then, a light shielding layer can also be prepared on the side of the first wiring area A30 in the first display panel A100 facing the light emitting surface of the first display panel A100. At this time, the position of the light shielding layer has a shielding effect on both the ambient light incident on the second display panel B100 and the light reflected from the first pixel B20 of the second display panel B100. Then, in the direction perpendicular to the plane where the display module 100 is located, the first wiring area A30 is arranged to at least partially overlap with the retaining wall B10, that is, in the direction perpendicular to the plane where the first display panel A100 is located, the wiring of the first wiring area A30 is arranged to at least partially overlap with the light emitting device A20, so that the light emitting device A20 located on the first display panel A100 that affects the transparent effect is partially aligned with the first wiring area A30 in the direction perpendicular to the surface where the display module 100 is located, which is conducive to reducing the influence of the device on the first display panel A100 on the area of ​​the transparent area A10, and avoiding the device located on the first display panel A100 from further compressing the area of ​​the transparent area A10.

[0052] In addition, the first wiring area A30 is arranged in a direction perpendicular to the plane where the display module 100 is located, and the first wiring area A30 at least partially overlaps with the retaining wall B10, which is also beneficial for arranging the first wiring area A30 and the usually arranged light-shielding layer at positions that have less influence on the light reflected by the first pixel B20, further ensuring that the overlapping area between the first pixel B20 and the transparent area A10 is larger, so that the first pixel B20 reflects more light, thereby making the display effect of the second display panel B100 better.

[0053] In one embodiment of the present application, continue to refer to Figure 1 As shown, the retaining wall B10 includes a first retaining wall portion B11, which is located between two adjacent first pixels B20 in the second direction X2. The first retaining wall portion B11 overlaps with M light-emitting devices A20 in a direction perpendicular to the plane where the display module 100 is located, where M is an integer greater than or equal to 1.

[0054] In a direction perpendicular to the surface of the display module 100, M light-emitting devices A20 are arranged to overlap with the first retaining wall portion B11, and as many light-emitting devices A20 as possible can be prepared along the edge side of the first pixel B10 in the second direction X2, so that the ratio of the first retaining wall portion B11 to the light-emitting device A20 is 1:M. Figure 1 As shown, three light-emitting devices A20 can be arranged at the position corresponding to the first blocking wall portion B11. At this time, the ratio of the first blocking wall portion B11 to the light-emitting device A20 is 1:3, or the number of the light-emitting devices A20 can be increased as much as possible when the light-emitting device A20 and the first blocking wall portion B11 are aligned with each other, which is beneficial to improve space utilization, improve the screen resolution of the first display panel A100, and improve the display effect of the first display panel A100.

[0055] Figure 4 A plan view of another display module provided in an embodiment of the present application.

[0056] In one embodiment of the present application, Figure 4 As shown, in a direction perpendicular to the plane where the display module 100 is located, the colors of at least two light emitting devices A20 overlapping the first barrier wall portion B11 are different. Figure 1 As shown, at least two light emitting devices A20 overlapping the first barrier wall portion B11 have the same color.

[0057] Taking the first display panel A100 as a Micro LED display panel as an example, the first display panel A100 at this time may include, for example, a red light-emitting device, a green light-emitting device, and a blue light-emitting device. For example, in a direction perpendicular to the plane where the display module 100 is located, the colors of at least two light-emitting devices A20 overlapping with the same first retaining wall portion B11 may include a red light-emitting device, a green light-emitting device, and a blue light-emitting device to form a complete pixel. Alternatively, in a direction perpendicular to the plane where the display module 100 is located, the colors of at least two light-emitting devices A20 overlapping with the same first retaining wall portion B11 are all red light-emitting devices, green light-emitting devices, or blue light-emitting devices; in addition, on this basis, it can also be set that the colors of the light-emitting devices A20 overlapped by two adjacent first retaining wall portions B11 in the first direction X1 are all different. For example, in two first barrier wall portions B11 adjacent to each other in the first direction X1, the colors of at least two light-emitting devices A20 overlapped by one of the first barrier walls B11 are both red light-emitting devices, and the colors of at least two light-emitting devices A20 overlapped by the other first barrier wall B11 are both green light-emitting devices, so that the multiple light-emitting devices A20 overlapped by the multiple first barrier walls B11 adjacent to each other in the first direction X1 together form a complete pixel.

[0058] Optionally, since the luminous efficiency of the red light-emitting device in the Micro LED is lower than that of the blue light-emitting device and the green light-emitting device, the problem of color deviation is prone to occur. Therefore, the number of red light-emitting devices in a pixel can be set to be greater than the number of blue light-emitting devices, and the number of red light-emitting devices can be greater than the number of green light-emitting devices. In this case, a first retaining wall B11 can be set to overlap with multiple red light-emitting devices, and another first retaining wall B11 can overlap with the blue light-emitting device and the green light-emitting device, that is, the light-emitting device A20 overlapping with one first retaining wall B11 has the same color, and the light-emitting device A20 overlapping with another first retaining wall B11 has a different color. It is also possible to set a first retaining wall B11 to overlap with the red light-emitting device and the blue light-emitting device, and another first retaining wall B11 to overlap with the red light-emitting device and the green light-emitting device, that is, the two first retaining walls B11 overlap with light-emitting devices A20 of different colors.

[0059] In an embodiment of the present application, depending on the actual use of the first display panel A100, whether the colors of at least two light-emitting devices A20 overlapping the first retaining wall portion B11 are the same, for example, the pixel distribution of the first display panel A100 or the color distribution of multiple light-emitting devices A20 overlapping the first retaining wall B1 are set according to needs, which is beneficial to improving the display capability of the first display panel A100. Multiple light-emitting devices A20 form a pixel, and the pixel distribution on the first display panel A100 is adjusted according to actual display needs.

[0060] Figure 5 A plan view of another display module provided in an embodiment of the present application.

[0061] In one embodiment of the present application, Figure 5 As shown, the first display panel A100 also includes a redundant bit A40. The retaining wall B10 includes a first retaining wall portion B11, which is located between two adjacent first pixels B20 in the second direction X2 and overlaps the redundant bit A40 in a direction perpendicular to the plane where the display module 100 is located.

[0062] When setting the redundant bit A40, two pairs of pads are usually set at the position where the light-emitting device A20 needs to be prepared, one pair of which is used to bind the light-emitting device A20, and the other pair is temporarily idle. When the light-emitting device A20 bound to one pair of pads functions normally, the light-emitting device A20 is not bound to the other pair of pads. When the light-emitting device A20 bound to one pair of pads does not function properly, another light-emitting device A20 can be bound to the other pair of pads without removing the light-emitting device A20 bound to the pad, that is, both pairs of pads are bound to the light-emitting device A20. In this way, there is one light-emitting device A20 that can emit light and one that cannot emit light in the light-emitting devices A20 bound to the two pairs of pads. In addition, when the light-emitting device A20 bound to one pair of pads does not function properly, the light-emitting device A20 bound to this pair of pads can also be removed, and then a light-emitting device A20 can be bound to the other pair of pads, so that only one pair of pads in the two pairs of pads is bound to the light-emitting device A20. In the above description, the pads that are not bound to the light emitting device A20 or the pads that are bound to the light emitting device A20 that does not emit light are all the redundant bits mentioned here.

[0063] Optionally, a pair of pads may include a first pad and a second pad, wherein the first pad is electrically connected to the pixel circuit, and the second pad is electrically connected to the power supply voltage. The first pads in the two pairs of pads may be electrically connected, and the second pads in the two pairs of pads may be electrically connected.

[0064] In the embodiment of the present application, the redundant position A40 is set on the first display panel A100, which is conducive to more convenient device replacement when the light-emitting device A20 cannot emit light normally, and is conducive to reducing the number of black spots on the first display panel A100 due to damage to the light-emitting device A20, thereby improving the display effect of the first display panel A100. In addition, the redundant position A40 is also overlapped with the first retaining wall portion B11, which is conducive to preventing the redundant position A40 from blocking the first pixel B20 and thus affecting the display effect of the first pixel B20.

[0065] Figure 6 A plan view of another display module provided in an embodiment of the present application.

[0066] In one embodiment of the present application, Figure 6As shown, the first retaining wall portion B11 also overlaps with M light-emitting devices in a direction perpendicular to the plane where the display module 100 is located, where M ≥ 1. In a direction perpendicular to the surface where the display module 100 is located, M light-emitting devices A20 are arranged to overlap with the first retaining wall portion B11, and as many light-emitting devices A20 as possible can be prepared along the edge side of the first pixel B10 in the second direction X2, so that the ratio of the first retaining wall portion B11 to the light-emitting device A20 is 1:M. This is conducive to increasing the number of light-emitting devices A20 as much as possible when the light-emitting devices A20 and the first retaining wall portion B11 are prepared in alignment, improving space utilization, improving the screen resolution of the first display panel A100, and improving the display effect of the first display panel A100.

[0067] Among them, the light-emitting devices A20 and the redundant bits A40 are arranged alternately in the first direction X1, and multiple redundant bits A40 are also arranged along the first direction X1. The M light-emitting devices A20 overlapping with the first barrier wall portion B11 may include at least M-1 redundant bits A40 also overlapping with the same first barrier wall portion B11.

[0068] In the embodiment of the present application, the redundant position A40 is set to overlap with the first blocking wall portion B11, and the redundant position A40 and the light-emitting device A20 are alternately arranged in the first direction X1. This is beneficial for each light-emitting device A20 to have a corresponding redundant position A40 adjacent to it in the first direction X1. When the light-emitting device A20 is damaged, a light-emitting device A20 can be supplemented at the adjacent redundant position A40, so that the light-emitting effect of the first display panel A100 is stable.

[0069] Figure 7 A plan view of another display module provided in an embodiment of the present application.

[0070] In one embodiment of the present application, Figure 7 As shown, the first display panel A100 also includes a redundant bit A40. The retaining wall B10 includes a second retaining wall portion B12, which is located between two adjacent first pixels B20 in the first direction X1 and overlaps with the redundant bit A40 in a direction perpendicular to the plane where the display module 100 is located.

[0071] In an embodiment of the present application, a redundant position A40 is set on the first display panel A100. With reference to the preparation of the redundant position A40 mentioned in the above embodiment, it is advantageous to set a corresponding light-emitting device A20 at a similar pad when the light-emitting device A20 is damaged, so that the corresponding position on the first display panel A100 can emit light normally, thereby reducing the number of black spots on the first display panel A100 due to damage to the light-emitting device A20 and improving the display effect of the first display panel A100. In addition, a plurality of light-emitting devices A20 are arranged to overlap with the first barrier wall portion B11, while a redundant position A40 overlaps with the second barrier wall portion B12, which is beneficial for making the light-emitting device A20 and the redundant position A40 overlap with different barrier wall portions, so that the first barrier wall portion B11 can overlap with as many light-emitting devices A20 as possible, avoiding the redundant position A40 occupying the position overlapping with the first barrier wall portion B11, thereby increasing the number of light-emitting devices A20 overlapping with the first barrier wall portion B11, thereby increasing the number of light-emitting devices A20 that can be set on the first display panel A100, and improving the display effect.

For example, the three light-emitting devices A20 of different colors can be red light-emitting devices, green light-emitting devices, and blue light-emitting devices, respectively, or light-emitting devices of other colors, which are not specifically limited here. In addition, the present application does not limit the number of light-emitting devices of different colors.

The edge of the transparent area A10 is formed by connecting multiple arc-shaped edges end to end, and multiple light-emitting devices A20 of different colors are prepared around the transparent area A10.

[0084] When the edge included in the transparent area A10 is an arc edge, the transparent area A10 is composed of a plurality of arc edges to form a circle, and a plurality of light emitting devices A20 can be distributed on the edge of the transparent area A10 and overlap with the retaining wall B10.

[0085] Fig.11 Another embodiment provided in this application is Figure 8 A partial plan view of the middle area E1. Fig.12 Another embodiment provided in this application is Figure 8 Schematic diagram of a local plan view of the middle area E1.

[0086] In one embodiment of the present application, Fig.11 As shown, at least one light emitting device A20 and at least one redundant bit A40 are disposed on one side of the transparent area A10.

[0087] For example, the transparent area A10 is a hexagon. The first pixel B10 is set to overlap with the transparent area A10. Optionally, the shape of the first pixel B10 is the same as that of the transparent area A10. Then, a barrier wall B10 is included between two adjacent first pixels B20, one side of the transparent area A10 overlaps with the barrier wall B20, and the light-emitting device A20 prepared on one side of the transparent area A10 also overlaps with the barrier wall B10. Optionally, as Fig.11 As shown, at least six light emitting devices A20 are arranged around the transparent area A10, and the colors of the light emitting devices A20 arranged around the transparent area A10 are not completely the same. Correspondingly, at least six redundant bits A40 may be arranged around the transparent area A10. Optionally, as Fig.12 As shown, at least twelve light emitting devices A20 are arranged around the transparent area A10, and the colors of the light emitting devices A20 arranged around the transparent area A10 are not completely the same. At least six redundant positions A40 can be arranged around the transparent area A10, and the redundant position A40 located on one side of the transparent area A10 can be located between two adjacent light emitting devices A20, which is beneficial to Fig.11As shown, one redundant position A40 corresponds to one light-emitting device A20. This method is beneficial for one redundant position A40 to be shared by two adjacent light-emitting devices A20, which is beneficial for reducing the number of spare light-emitting devices A20 prepared on the first display panel A100, reducing the number of redundant positions A40 prepared, and improving the space utilization of the first display panel A100.

[0088] In the embodiment of the present application, both the light-emitting device A20 and the redundant position A40 are set on one side of the transparent area A10, so that there is at least one redundant position A40 adjacent to the light-emitting device A20. This is beneficial for placing the light-emitting device A20 by utilizing the redundant position A40 adjacent to the light-emitting device A20 on a certain side when the light-emitting device A20 is damaged, so as to replace the damaged light-emitting device A20 for emitting light, and is beneficial for avoiding the appearance of black spots on the edge of the transparent area A10, which affects the display effect of the first display panel A100.

[0089] In one embodiment of the present application, continue to refer to Fig.11 As shown, the retaining wall portion B13 between two adjacent first pixels B20 overlaps with both the light emitting device A20 and the redundant bit A40 in a direction perpendicular to the plane where the display module 100 is located.

[0090] In the embodiment of the present application, the light emitting device A20 and the redundant position A40 located on one side of the transparent area A10 are arranged to overlap with the retaining wall portion B13, which is conducive to preventing the redundant position A40 from occupying the position of the transparent area A10, and ensuring that the transparent area A10 has a larger light emitting area in the direction perpendicular to the surface of the display module 100. In addition, it is conducive to making the positions of the light emitting device A20 and the redundant position A40 closer, so that when the light emitting device A20 is placed in the redundant position A40 to compensate for the light emission, it can be close to the position where the faulty light emitting device is originally supposed to emit light, so that the light emission effect error is small.

[0091] Fig.13 Another embodiment provided in this application is Figure 8 Schematic diagram of a local plan view of the middle area E1.

[0092] In one embodiment of the present application, Fig.13 As shown, the light emitting devices A20 disposed on one side of the transparent area A10 have the same color.

[0093] In the embodiment of the present application, the light emitting devices A20 disposed on one side of the transparent area A10 have the same color, which is conducive to disposing a plurality of light emitting devices A20 of the same color on one side of the transparent area A10, reducing the complexity of preparing the light emitting devices A20, and improving the preparation efficiency of the light emitting devices A20. In some cases, there may be a situation where the light emitting devices A20 of different colors are of different sizes. Disposing the light emitting devices A20 of the same color on one side of the transparent area A10 is also conducive to improving the arrangement regularity of the light emitting devices A20 on one side of the transparent area A10, providing the possibility of disposing as many light emitting devices A20 as possible.

[0094] In one embodiment of the present application, continue to refer to Fig.13 As shown, the light emitting devices A20 overlapped by the retaining wall portion B13 between two adjacent first pixels B20 in a direction perpendicular to the plane where the display module 100 is located have the same color. This is beneficial to make the light output colors of multiple light emitting devices A20 overlapping with the same retaining wall portion B13 the same, and is beneficial to improve the light output brightness at the overlapped portion with the same retaining wall portion B13, avoiding the problem of light crosstalk in the portion overlapping with the same retaining wall portion B13.

[0095] Fig.14 Another embodiment provided in this application is Figure 8 Schematic diagram of a local plan view of the middle area E1.

[0096] In one embodiment of the present application, Fig.14 As shown, the light emitting device A20 is arranged on part of the transparent area A10, and the redundant position A40 is arranged on part of the transparent area A10. Only the light emitting device A20 is arranged on part of the transparent area A10, and only the redundant position A40 is arranged on part of the transparent area A10, so as to avoid the redundant position A40 occupying the space of the light emitting device A20, which is beneficial to increase the number of the light emitting devices A20 prepared on one side of the transparent area A10, and also beneficial to increase the number of the redundant position A40 prepared on one side of the transparent area A10, and provide more favorable guarantee for the normal display of the first display panel A100.

[0097] In one embodiment of the present application, continue to refer to Fig.14 As shown, the retaining wall portion B13 between two adjacent first pixels B20 overlaps with the redundant position A40 in a direction perpendicular to the plane where the display module 100 is located, which is beneficial to avoid the redundant position A40 occupying the position of the transparent area A10, thereby ensuring that the transparent area A10 has a larger light output area in a direction perpendicular to the surface where the display module 100 is located.

[0100] from Fig.15 It can be seen that the colors of the light-emitting devices A20 arranged on different sides of the same transparent area A10 are different. Optionally, light-emitting devices A20 of different colors are respectively arranged on three adjacent sides of the transparent area A20, so that there are at least three colors of light-emitting devices A20 around the transparent area A10, and the positions of the three different colors of light-emitting devices A20 distributed around the same transparent area A10 are relatively close, and the three different colors of light-emitting devices A10 can be used to form a second pixel A60 on the first display panel A100.

[0101] Further, around a first pixel B20, when the first pixel B20 is as follows Fig.13 In the case of the hexagon shown, the ratio of the projection of a first pixel B10 in the direction perpendicular to the surface of the display module 100 to the surrounding second pixels A60 composed of light-emitting devices A20 is at least 1:2. This method allows the preparation density of the light-emitting devices A10 on the first display panel A100 to be higher, which is conducive to ensuring that the pixel resolution of the first display panel A100 reaches a certain level while allowing the light of the first pixel B10 to pass through, meeting higher display requirements.

[0102] In one embodiment of the present application, continue to refer to Fig.15 As shown, the first pixel B20 includes a first sub-pixel B21, a second sub-pixel B22, and a third sub-pixel B23, and the three sub-pixels are adjacent to each other. The third retaining wall portion B14 is located between the first sub-pixel B21 and the second sub-pixel B22, the fourth retaining wall portion B15 is located between the second sub-pixel B22 and the third sub-pixel B23, and the fifth retaining wall portion B16 is located between the first sub-pixel B21 and the third sub-pixel B23.

[0103] Among them, the color of the light-emitting device A20 overlapping the third barrier wall portion B14 is different from the color of the light-emitting device A20 overlapping the fourth barrier wall portion B15, and / or the color of the light-emitting device A20 overlapping the fourth barrier wall portion B15 is different from the color of the light-emitting device A20 overlapping the fifth barrier wall portion B16, and / or the color of the light-emitting device A20 overlapping the third barrier wall portion B14 is different from the color of the light-emitting device A20 overlapping the fifth barrier wall portion B16.

[0104] Alternatively, if Fig.15As shown, the retaining wall overlaps with at least one light emitting device A20, wherein the color of the light emitting device A20 overlapped by the third retaining wall B14 is different from the color of the light emitting device A20 overlapped by the fourth retaining wall B15, and the color of the light emitting device A20 overlapped by the fourth retaining wall B15 is different from the color of the light emitting device A20 overlapped by the fifth retaining wall B16, and the color of the light emitting device A20 overlapped by the third retaining wall B14 is different from the color of the light emitting device A20 overlapped by the fifth retaining wall B16. In this way, the colors of the light emitting devices A20 overlapped by the third retaining wall B14, the fourth retaining wall B15, and the fifth retaining wall B16 adjacent to each other in the direction perpendicular to the surface of the display module 100 are all different, and the three light emitting devices A20 are arranged in a triangular array to form a second pixel A60 together. In addition, the three retaining wall portions formed between the other two adjacent three first pixels B20 may also overlap with the light-emitting devices A20 of different colors, respectively, so that the three adjacent light-emitting devices A20 of different colors form another second pixel A60.

[0105] Fig.16 Another embodiment provided in this application is Figure 8 Schematic diagram of a local plan view of the middle area E1.

[0106] Alternatively, if Fig.16 As shown, the color of the light-emitting device A20 overlapped by the third barrier wall portion B14 is different from the color of the light-emitting device A20 overlapped by the fourth barrier wall portion B15, or the color of the light-emitting device A20 overlapped by the fourth barrier wall portion B15 is different from the color of the light-emitting device A20 overlapped by the fifth barrier wall portion B16, and the color of the light-emitting device A20 overlapped by the third barrier wall portion B14 is different from the color of the light-emitting device A20 overlapped by the fifth barrier wall portion B16. In some cases, the color of the light-emitting device A20 overlapped by the third barrier wall portion B14 can be the same as the color of the light-emitting device A20 overlapped by the fourth barrier wall portion B15, the color of the light-emitting device A20 overlapped by the fourth barrier wall portion B15 can be different from the color of the light-emitting device A20 overlapped by the fifth barrier wall portion B16, and the color of the light-emitting device A20 overlapped by the third barrier wall portion B14 can also be different from the color of the light-emitting device A20 overlapped by the fifth barrier wall portion B16. The above embodiment mentioned that a second pixel A60 may include two color light emitting devices A20, and the number of two color light emitting devices A20 in the same second pixel A60 may be different. Fig.16 As shown, a group of light emitting devices A20 of different colors respectively overlapping with the third barrier wall portion B14, the fourth barrier wall portion B15, and the fifth barrier wall portion B16 can also form a second pixel A60.

[0107] In one embodiment of the present application, continue to refer to Fig.15As shown, the second pixel A60 includes a first light-emitting device A21, a second light-emitting device A22, and a third light-emitting device A23, the first pixel B20 includes a first sub-pixel B21, a second sub-pixel B22, and a third sub-pixel B23, and the three sub-pixels are adjacent to each other; the third blocking wall portion B14 is located between the first sub-pixel B21 and the second sub-pixel B22, the fourth blocking wall portion B15 is located between the second sub-pixel B22 and the third sub-pixel B23, and the fifth blocking wall portion B16 is located between the first sub-pixel B21 and the third sub-pixel B23.

[0108] The first light emitting device A21 overlaps with the third blocking wall portion B14, the second light emitting device A22 overlaps with the fourth blocking wall portion B15, and the third light emitting device A23 overlaps with the fifth blocking wall portion B16.

[0109] In the embodiment of the present application, three adjacent retaining walls are arranged to overlap the three light-emitting devices A20 in the same second pixel A60, which is conducive to arranging the three adjacent light-emitting devices A20 in a triangular array to form a second pixel A60. The transparent area A10 is a hexagon as an example. Fig.13 As shown, in the technical solution of the present application, a second pixel A60 can be formed at the intersection of three adjacent retaining wall portions, then at least six second pixels A60 can be formed around the transparent area A10, and the ratio of the number of the transparent area A10 to the second pixels A60 around it is 1:6, which is beneficial to increase the number of pixels on the first display panel A100 and improve the display effect of the first display panel A100.

[0110] Fig.17 A method provided in the embodiment of the present application Fig.15 Schematic diagram of a partial cross section of the middle area E2.

[0111] In one embodiment of the present application, Fig.17 As shown, the light emitting device A20 includes a first electrode N1 and a second electrode N2, and the first electrode N1 of the light emitting device A20 in the same second pixel A60 is electrically connected through the same via K1. Optionally, the first electrode N1 of the light emitting device A20 is a cathode. Fig.15As shown, the second pixel A60 located in the area E2 includes a first light emitting device A21, a second light emitting device A22, and a third light emitting device A23, and the first light emitting device A21, the second light emitting device A22, and the third light emitting device A23 overlap with the third blocking wall portion B14, the fourth blocking wall portion B15, and the fifth blocking wall portion B16 that are adjacent to each other. The first light emitting device A21, the second light emitting device A22, and the third light emitting device A23 are adjacent to each other and are close to each other to form a second pixel A60, and the first electrode N1 of the light emitting device A20 in the same second pixel A60 can be electrically connected through the same via K1, which is beneficial to avoid redundant wiring and also beneficial to reduce the number of vias on the first display panel A100.

[0112] In one embodiment of the present application, continue to refer to Figure 1 , Figure 8 , Fig.10 As shown, the first pixel B20 has the same shape as the transparent area A10, which is beneficial for making the shape of the first pixel B20 fit the shape of the transparent area A10, thereby facilitating increasing the overlapping area of ​​the first pixel B20 and the transparent area A10 and increasing the light output of the first pixel B20.

[0113] In one embodiment of the present application, continue to refer to Figure 1 As shown, the first display panel A100 further includes a plurality of light emitting devices A20, which are arranged along a first direction X1, and the first direction X1 is a direction parallel to the plane where the display module 100 is located. The width of the first pixel B20 in the first direction X1 is greater than or equal to twice the width of the light emitting device A20 in the first direction X1.

[0114] In the embodiment of the present application, the width of the first pixel B20 is set to be larger, so that the area of ​​the first pixel B20 that can reflect light may be larger than the light emitting area of ​​the light emitting device A20. This is beneficial for preventing the light reflected by the first pixel B20 located below the light emitting device A20 in a direction perpendicular to the surface of the display module 100 from being easily blocked by devices such as the light emitting device A20, and allows the transparent area A10 to transmit more light reflected by the first pixel B20, thereby improving the display effect of the second display panel B100.

[0115] Fig.18 A schematic plan view of another display module provided in an embodiment of the present application, Fig.19 A cross-sectional schematic diagram of another display module provided in an embodiment of the present application.

[0116] In one embodiment of the present application, Fig.18 , Fig.19As shown, the display module 100 further includes a cover plate C100, and the cover plate C100 includes an edge region C10, and the edge region C10 does not overlap with the transparent region A10, the first pixel B20, and the light-emitting device A20 in a direction perpendicular to the plane where the display module 100 is located. The edge region C10 is provided with a pattern layer C11. The cover plate C100 in the embodiment of the present application is a transparent structure, which is conducive to ensuring that the display module 100 allows light to pass through.

[0117] The display module 100 further includes a first transparent optical adhesive layer OCA1 and a second transparent optical adhesive layer OCA2. The first transparent optical adhesive layer OCA1 is located between the cover plate C100 and the first display panel A100, and can fix the cover plate C100 and the first display panel A100 together. The second transparent optical adhesive layer OCA2 is located between the first display panel A100 and the second display panel B100, and can fix the first display panel A100 and the second display panel B100 together.

[0118] The pattern layer C11 is located in the edge region C10 . Optionally, the pattern layer C11 includes a background image. The second display panel B100 can display the same image as the pattern layer C11 , thereby improving the visual integration effect of the display module 100 .

[0119] In one embodiment of the present application, continue to refer to Fig.18 As shown, the pattern layer C11 includes a color block C111, and the color block C111 has the same color as a part of the light-emitting device A20.

[0120] The pattern layer C11 includes a pattern composed of a plurality of color blocks C111; wherein, the image in the pattern layer C11 can be obtained by printing, photolithography and other technologies, and fundamentally, the pattern on the pattern layer C11 is also formed by splicing individual color blocks C111. Optionally, when the second display panel B100 displays a background pattern, it can display an image that is the same as the pattern of the pattern layer C11, so that the visual effects of the second display panel B100 and the pattern layer C11 are integrated.

[0121] In the related art, it can be known from the above content that the display module including two superimposed display panels can be applied to the field of vehicle-mounted display. In the application, the first display panel can display the working picture, and the second display panel can be used as a background panel to display the picture with the same pattern as the first pattern layer, forming an integrated visual effect of the display area and the non-display area, which is conducive to improving the display effect and thus improving the user's viewing experience. However, it was found in the application that the picture effect of the second display panel when displaying the background pattern was different from the picture effect presented by the first pattern layer in the non-display area, and the visual effect integration effect was not good.

[0122] The inventor of the present application proposes setting the color block C111 to have the same color as that of some light-emitting devices A20, so that the colors of some light-emitting devices A20 located in the first display panel A100 are the same as the color of the color block C111, which is beneficial to improving the consistency of display effects between the panel display area and the edge area, and improving the visual integration effect of the display module 100.

[0123] In one embodiment of the present application, the number of color blocks C111 and the first pixel B20 and / or the transparent area A10 per unit area is set to be the same. Optionally, in a direction perpendicular to the surface where the display module 100 is located, the first pixel B20 corresponds to the transparent area A10. Setting the number of color blocks C111 and the first pixel B20 per unit area to be the same is conducive to making the resolution of the pattern layer C11 including multiple color blocks C111 consistent with the resolution of the second display panel B100, which is conducive to improving the picture effect of the second display panel B100 when displaying the background pattern to be consistent with the picture effect presented by the pattern layer C11 in the edge area C10, and is conducive to further improving the visual integration effect.

[0124] In one embodiment of the present application, the first display panel is a self-luminous display panel, and the second display panel is a reflective display panel.

[0125] Optionally, the first display panel A100 is an OLED (Organic Light Emitting Diode) display panel, a Micro OLED (Micro Organic Light Emitting Diode) display panel, or a Micro LED (Micro Light Emitting Diode), which is beneficial for utilizing the first display panel A100 to realize the light transmission function, so that the light generated by the second display panel B100 can pass through.

[0126] The second display panel B100 is a reflective display panel. Optionally, the second display panel B100 is an electronic paper display screen, and its performance of reflecting light is relatively consistent with the visual effect of reflecting light of the pattern layer C11, which is conducive to improving the consistency of the display effect of the second display panel B100 and the pattern layer C11. It should be noted that the multiple first pixels B20 in the second display panel B100 can be different colors, and the first pixel B20 can include electrophoretic particles of multiple colors, so that the first pixel B20 reflects light to display color. In addition, one first pixel B20 can correspond to one color resistance, and different color resistances can make the first pixel B20 reflect light to display different colors. The color display in the second display panel B100 can be realized by combining multiple first pixels B10 corresponding to different color resistances.

The display device 200 can be a vehicle-mounted display device or other device including a background display device, which is not limited in the present application.

[0129] In the display device 200, the first pixel B20 is at least partially overlapped with the transparent area A10 in a direction perpendicular to the plane where the display module is located, and the retaining wall B10 located on the second display panel B100 at least partially does not overlap with the transparent area A10, and the transparent area A10 is used to enable the first pixel B20 to smoothly emit light toward the light-emitting surface of the display module 100. Further, the embodiment of the present application is conducive to ensuring that most of the light reflected by the first pixel B10 can be emitted outside the display module 100, thereby improving the display effect of the display module 100. In addition, the present solution is beneficial for more scientifically setting the device positions in the first display panel A100 and the second display panel B100 through the position correspondence between the transparent area A10 and the blocking wall B10 and the first pixel B20, so that the alignment preparation of the first display panel A100 and the second display panel B100 is more regular, thereby avoiding the situation where the devices on the first display panel A100 and the second display panel B100 are messyly aligned and thus affect each other's light output; thereby, the first display panel A100 can emit light normally, and the second display panel B100 located therebelow can also reflect more light toward the light-emitting surface of the display module 100, thereby improving the display effect of the display module 100.
