Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a display module and display device. Background Technology

[0002] As in-vehicle systems continue to develop and improve, people are paying more and more attention to in-vehicle displays. They not only have many requirements for the appearance of the display, but also for the internal performance of the display, such as optical performance, power consumption and reliability.

[0003] In recent years, large central control screens have gradually become the mainstream of in-vehicle displays. The sense of style and convenient operation brought by large-size display screens to users are obvious. In-vehicle display screens are usually fixed in the car, where the ambient brightness is limited, and they need to meet the needs of both the driver and passengers. For example, the display screen needs to have high contrast in certain viewing angles, while visibility needs to be reduced in other specific viewing angles. This is a difference in requirements between in-vehicle display screens and display screens in other application fields. However, it is currently difficult for display screens to meet the above requirements at the same time. Special viewing angle requirements urgently need to be addressed with technical solutions. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a display module and display device that can ensure that the display module has a high contrast within a specific viewing angle range.

[0005] In a first aspect, this application provides a display module, comprising:

[0006] A first display panel, the first display panel including a first display area; a second display panel, the second display panel including a second display area; in a direction perpendicular to the display module, the projections of the first display area and the second display area overlap;

[0007] The first display panel includes a first array substrate, the first array substrate includes a first scan line and a first data line, and the first display panel includes a plurality of color display areas, with a first non-display area formed between adjacent color display areas;

[0008] The second display panel includes a second array substrate, multiple monochrome display areas, and multiple light-blocking components;

[0009] In the direction perpendicular to the display module, the projections of the color display area and the monochrome display area overlap, the projections of the monochrome display area and the light-blocking component do not overlap, the projection of the light-blocking component overlaps with the projections of the first non-display area and / or the color display area, and a plurality of the light-blocking components are arranged or arrayed along a first direction, the first direction being the extension direction of the first scan line, or the first direction being the extension direction of the first data line.

[0010] Secondly, this application provides a display device, which includes the display module and backlight module described in the first aspect, wherein the first display panel and the second display panel in the display module are both liquid crystal display panels.

[0011] The first display panel includes touch electrodes, and the first display panel is located on the side of the second display panel away from the backlight module;

[0012] Alternatively, the second display panel may include touch electrodes, and the second display panel may be located on the side of the first display panel away from the backlight module.

[0013] Compared with the prior art, the display module and display device provided by the present invention achieve at least the following beneficial effects:

[0014] This application provides a display module and a display device. The display module includes a first display panel and a second display panel, wherein the first display panel is a color display and the second display panel is a monochrome display. The first display area of ​​the first display panel and the second display area of ​​the second display panel are correspondingly arranged. The second display panel can perform corresponding area dimming, that is, provide light to the display area of ​​the first display panel or the area above the preset gray level, and do not provide light to the undisplayed area or the area below the preset gray level. Moreover, the second display panel can adjust different brightness according to the specific gray level displayed by the first display panel. Thus, the brightness of the image displayed by the superimposed two display panels is more precisely controlled, which increases the brightness difference between bright and dark areas, thereby giving the display module a higher contrast ratio.

[0015] Meanwhile, the second display panel also includes multiple light-blocking components. These components do not overlap with the display area of ​​the second display panel and are arranged or arrayed along a first direction. The first direction can be set as the extension direction of the first scan line or the extension direction of the first data line on the first display panel, depending on the specific viewing angle requirements and the specific position of the display module. For example, when the display module is placed with the extension direction of the first scan line as its left-right orientation, the first scan line extends in the left-right direction and the first data line extends in the up-down direction within the horizontal plane of the first display panel. If the visibility needs to be reduced when viewed obliquely from above and below the display module, the light-blocking components can be arranged to extend along the direction of the first scan line or be arranged or arrayed along the direction of the first data line. This can block the oblique light from above and below the display module, thereby reducing the visibility at large viewing angles above and below. Furthermore, the specific number of light-blocking components can be adjusted according to specific visibility requirements so that the entire display module meets specific viewing angle requirements.

[0016] The display module and display device provided by the present invention integrate multiple light-blocking components on a monochrome display panel, which can reduce the visibility in specific viewing angles while ensuring that the display module has a high contrast. On the one hand, it meets the specific viewing angle requirements, and on the other hand, the display module is highly integrated and has a low cost. Attached Figure Description

[0038] The embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Please refer to Figures 1-6 , Figure 1 This is a schematic diagram of a display module provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of another display module provided in an embodiment of the present invention. Figure 3 This is a top view schematic diagram of a first display panel provided in an embodiment of the present invention. Figure 4 This is a top view schematic diagram of a second display panel provided in an embodiment of the present invention. Figure 5 This is a top view schematic diagram of another second display panel provided in an embodiment of the present invention. Figure 6 for Figure 3 The first display panel and Figure 4 A cross-sectional schematic diagram of the second display panel along section line A-A'; an embodiment of the present invention provides a display module 00, which includes a first display panel 1 and a second display panel 2. The stacking order of the first display panel 1 and the second display panel 2 is not limited. The first display panel 1 includes a first display area 10, and the second display panel 2 includes a second display area 20. In the direction Z perpendicular to the display module 00, the projections of the first display area 10 and the second display area 20 overlap.

[0040] Please refer to Figure 3 The first display panel 1 includes a first array substrate 11, which includes a first scan line (scan) and a first data line (data). The first scan line (scan) and the first data line (data) define a plurality of display units. Each display unit includes a color display area P1, which includes at least two different color display areas. Optionally, the color display area P1 includes red, green, and blue color display areas. A first non-display area NP1 is formed between adjacent color display areas P1. Please refer to [reference needed]. Figure 4The second display panel 2 includes a second array substrate 21 and has multiple monochrome display areas P2. That is, the second display panel 2 does not have a color display function; when the second display panel 2 is lit alone, it can only display black and white images. By stacking the first display panel 1 and the second display panel 2, the second display panel 2 can perform regional dimming corresponding to the first display panel 1. Specifically, it provides light to the display area of ​​the first display panel 1 or areas displaying a preset grayscale or higher, while areas not displayed by the first display panel 1 or areas displaying a preset grayscale or lower are not illuminated. Furthermore, the second display panel 2 can adjust its brightness according to the specific grayscale displayed by the first display panel 1, allowing for more precise control of the regional brightness of the display module 00, increasing the brightness difference between bright and dark areas, and thus giving the display module 00 a higher contrast ratio.

[0041] Please refer to Figures 3-6 The second display panel 2 also includes multiple light-blocking components B. In the direction Z perpendicular to the display module O0, the projections of the light-blocking components B and the monochrome display area P2 do not overlap. The projections of the color display area P1 of the first display panel 1 and the monochrome display area P2 of the second display panel 2 overlap. Optionally, the projection of the light-blocking component B can be configured to overlap with the projection of the first non-display area NP1 of the first display panel 1, and / or the projection of the light-blocking component B can overlap with the projection of the color display area P1 of the first display panel 1. This part can be configured according to the specific arrangement of the display units of the first display panel 1, such as... Figure 6 As shown, the projection of the light-blocking component B overlaps with the projection of the first non-display area NP1 of the first display panel 1. Multiple light-blocking components B can extend along the second direction Y and be arranged along the first direction X. Figures 3-5 Taking the first direction X as the extension direction of the first scan line as an example, in

[0042] In other embodiments of the present invention, the first direction X can also be the extension direction of the first data line data. This part 5 is determined according to the specific viewing angle requirements and the placement position of the display module 00. For example, the viewing angle requirement is the first direction X.

[0043] To reduce visibility in the X direction, the light-blocking component B needs to extend along the second direction Y. The light-blocking component B can block some of the light visible from an angle in the first direction X, thereby reducing the visibility from an angle in the first direction X. When the extension direction of the first scan line (scan) of the first display panel 1 is the first direction X, the extension direction of the light-blocking component B...

[0044] The direction of extension of the light-blocking component B is consistent with the extension direction of the first data line data, or when the extension direction of the first data line 0 data of the first display panel 1 is the first direction X, the extension direction of the light-blocking component B is consistent with the extension direction of the first scan line scan.

[0045] Optional, such as Figure 4 As shown, when the light-blocking component B extends along the second direction Y, it can penetrate the top and bottom of the second display panel 2 along the second direction Y, and the light-blocking component B is arranged along the first direction X, thereby reducing...

[0046] Reduce visibility in the first X direction; optional, such as Figure 5 As shown, the light-blocking component B extends along the second direction Y, and 5 can be located on at least one side of the monochrome display area P2 along the first direction X, and is arranged in an array on the second display panel 2, thereby reducing the visibility in the first direction X. Figure 4 and Figure 5 In this configuration, the light-blocking components B are all elongated strips. The light-blocking components B can extend continuously or be intermittently arranged. For example, they can penetrate the entire second display panel 2 or at least penetrate a portion of the monochrome display area P2, or they can be located only on one side of a single monochrome display area P2. This portion can be determined according to...

[0047] The material properties of the light-blocking component B and specific visibility requirements are set accordingly. This invention does not limit the specific settings. Furthermore, the number of light-blocking components B can be adjusted according to specific visibility requirements so that the entire display module 00 meets specific viewing angle requirements. It should be noted that in other embodiments of this invention, the light-blocking component B may also be of other shapes, such as block-shaped or ring-shaped, with the ring-shaped light-blocking component B at least partially surrounding one or more monochrome display areas P2. The setting of this portion of the light-blocking component B can be adjusted accordingly according to the specific viewing angle requirements, and this invention does not limit the specific settings.

[0048] By stacking the first display panel 1 and the second display panel 2, that is, by integrating multiple light-blocking components B on the monochrome display panel, the display module 00 can reduce the visibility in a specific viewing angle direction while ensuring that it has a high contrast. On the one hand, it meets the specific viewing angle requirements, and on the other hand, the display module 00 is highly integrated and has a low cost.

[0049] Optional, such as Figure 6 As shown, the first display panel 1 is a micron-level light-emitting diode (Micro LED) display panel, the second display panel is a liquid crystal display panel, and the second display panel 2 is located above the first display panel 1. In other embodiments of the present invention, when the second display panel 2 is located above the first display panel 1, the first display panel 1 may also be a sub-millimeter-level light-emitting diode (Mini LED) display panel, an organic light-emitting diode (OLED) display panel, or a liquid crystal display panel, etc. When the first display panel 1 is located above the second display panel 2, such as... Figure 7 As shown, Figure 7 for Figure 3 The first display panel and Figure 4Another cross-sectional view of the second display panel along section line A-A', where the first display panel 1 and the second display panel 2 can both be liquid crystal display panels.

[0050] Optional, please refer to Figure 3 and Figure 8 As shown, Figure 8 This is a top view schematic diagram of another second display panel provided in an embodiment of the present invention; the first display panel 1 has a first resolution, and the second display panel 2 has a second resolution. When the second display panel 2 is located on the backlight side of the first display panel 1, that is, as shown... Figure 2 As shown, when the second display panel 2 is located below the first display panel 1, the second resolution is equal to or less than the first resolution; or, when the first display panel 1 is located on the backlight side of the second display panel 2, that is, as shown... Figure 1 As shown, when the first display panel 1 is located below the second display panel 2, the first resolution is equal to the second resolution. Figure 8 In the middle, the resolution of the second display panel 2 is lower than that of the second display panel 2. Figure 3 If the resolution of the first display panel 1 is the same as the resolution of the first display panel 1, then the second display panel 2 can be located below the first display panel 1. To ensure the overall display sharpness of the display module 00, the first display panel 1 is a color display panel, serving as the display panel for the image; that is, the resolution of the first display panel 1 is the same as the display resolution of the display module 00. The second display panel 2 is a monochrome display panel.

[0051] The panel displays only black and white images. As a dimming display panel, its main function is to enhance the contrast of the first display panel 1. Therefore, when the second display panel 2 is positioned above the first display panel 1, its...

[0052] The resolution must be consistent with that of the first display panel 1 to avoid affecting the resolution of the display module 00. When the second display panel 2 is located below the first display panel 1, its resolution can be consistent with or slightly lower than that of the first display panel 1. In this case, the resolution of the display module 00...

[0053] The resolution is still determined by the first display panel 1, i.e., the topmost display panel. The lower resolution of the second display panel 20 compared to the first display panel 1 will not affect the overall resolution of the display module 00.

[0054] The second display panel 2 is easier to manufacture with a lower resolution. This part can be set according to the fineness of the brightness difference required by the display module 00 and the specific contrast ratio to be achieved. When the display module 00 needs to achieve a large contrast ratio and a high level of fineness, the resolution of the second display panel 2 can be set to be equal to the resolution of the first display panel 1.

[0055] 5. Optionally, the film layers stacked on the first array substrate 11 and the second array substrate 21 are the same. For example... Figure 9

[0056] As shown, Figure 9 This is a schematic cross-sectional view of a first array substrate provided in an embodiment of the present invention. The first array substrate 11 provided in this embodiment of the present invention includes a first substrate 110, and a buffer layer 111, a semiconductor layer 112, a first insulating layer 113, a gate metal layer 114, a second insulating layer 115, and a source layer 110 are sequentially stacked on one side of the first substrate 110.

[0057] The system comprises a drain metal layer 116, a first planarization layer 117, a first common electrode layer 118, a third insulating layer 119, and a first driving electrode layer 120. Optionally, a light-shielding metal layer (not shown) is further disposed between the buffer layer 111 and the semiconductor layer 112. Optionally, the film structure of the first array substrate 11 can also be other structures, and the present invention is not limited thereto. Setting the stacked film layers of the first array substrate 11 and the second array substrate 21 to be the same facilitates the fabrication of the array substrate of the display module 00 and ensures that the driving capabilities of the first display panel 1 and the second display panel 2 are consistent, thereby ensuring the synchronization and consistency of the display in the display module 00.

[0058] Optional, such as Figure 7 As shown, both the first display panel 1 and the second display panel 2 are liquid crystal display panels. The first display panel 1 includes a first array substrate 11 and a first opposing substrate 12. The first opposing substrate 12 includes a first black matrix 121 with multiple openings and a first color resist layer 122. The first color resist layer 122 is at least partially located within the openings of the first black matrix 121. The first black matrix 121 is located in the first non-display area NP1 of the first display panel 1, and the first color resist layer 122 is located in the color display area P1 of the first display panel 1. The second display panel 2 includes a second array substrate 21 and a second opposing substrate 22. The second opposing substrate 22 includes a second black matrix 221, which also has multiple openings, but the second opposing substrate 22 does not include a color resist layer. In the direction Z perpendicular to the display module 00, the projections of the first black matrix 121 and the second black matrix 221 overlap, thus ensuring that the projections of the openings of the first black matrix 121 and the openings of the second black matrix 221 overlap.

[0059] Optional, please continue to refer to Figure 4 , Figure 5 and Figure 7Along the first direction X, the light-blocking component B is located at least on one side of the monochrome display area P2, and in the direction Z perpendicular to the display module 00, the projection of the light-blocking component B is located within the projection of the first non-display area NP1, thereby avoiding the light-blocking component B from obstructing the light-emitting area of ​​the first display panel 1 and ensuring the brightness of the first display panel 1 when viewed directly. Furthermore, the projection of the light-blocking component B can be positioned within the projection of the second black matrix 221 of the second display panel 2, and the projection of the second black matrix 221 overlaps with the projection of the first black matrix 121, thereby ensuring that the display module 00 obtains a larger opening and ensuring the overall brightness of the display module 00.

[0060] Optional, such as Figures 10-12 As shown, Figure 10 This is a top view schematic diagram of yet another second display panel provided in an embodiment of the present invention. Figure 11 for Figure 10 Enlarged view of area S on the second display panel. Figure 12 for Figure 3 The first display panel and Figure 10 A cross-sectional schematic diagram of the second display panel along section line A-A'; in the direction Z perpendicular to the display module 00, the projection of the light-blocking component B may overlap with the color display area P1 of the first display panel 1, wherein the second array substrate 21 includes a light-shielding layer M, and the projection of the light-blocking component B is disposed within the projection of the light-shielding layer M. Figure 10 Taking the light-blocking component B and the light-shielding layer M as an example along the extension direction of the first scan line, in other embodiments of the present invention, the light-blocking component B and the light-shielding layer M may also be along the extension direction of the first data line, and the present invention does not limit them.

[0061] Optional, please refer to Figure 11 and Figure 12 The light-shielding layer M can be a metal light-shielding layer MZ. The second array substrate 21 includes a second substrate 210, a related film layer of the driving transistor (not shown in the figure), and a metal light-shielding layer MZ located between the second substrate 210 and the film layer of the driving transistor. The metal light-shielding layer MZ is used to prevent the active area of ​​the driving transistor from being affected by backlight and to prevent light leakage. The pattern of the light-shielding layer M is added in the same layer as the metal light-shielding layer MZ. At the same time, the projection of the light-blocking component B is located within the projection of the added metal light-shielding layer MZ to prevent the light-blocking component B from causing uneven brightness in the light-transmitting area of ​​the display module 00. Reusing the metal light-shielding layer MZ as the shielding layer M can also avoid additional processes and save costs.

[0062] Optional, please continue to refer to Figure 11The second display area 20 includes multiple sub-pixel units PP. The sub-pixel units PP overlap with the color display area P1 of the first display panel 1. The sub-pixel unit PP includes a pixel electrode PE. The pixel electrode PE has at least two extending directions. There is a connecting portion PEC between the pixel electrodes PE with different extending directions. In the direction Z perpendicular to the display module 00, the projection of the light blocking component B overlaps with the projection of the connecting portion PEC. At this point, the pixel electrodes of the first display panel 1 and the second display panel 2 can be set to extend in the same direction, and the projections of the pixel electrode connection portions of the two display panels in the direction Z perpendicular to the display module 00 overlap. At the connection portion PEC, the liquid crystal molecules will be disturbed by the torsional torque generated by the electric field in at least two directions, causing the liquid crystal molecules to rotate erratically or not at all. This results in very low brightness in the area where the connection portion PEC is located during high grayscale display. Therefore, setting a light-blocking component B and a metal light-shielding layer MZ in this part can reduce the brightness when viewed directly and further reduce the visibility when viewed obliquely to a certain extent, thereby ensuring a better display effect while meeting the viewing angle requirements of the display module 00. It should be noted that the metal light-shielding layer MZ can be set continuously, that is, along the extension direction of the light-blocking component B, the metal light-shielding layer MZ runs through the entire second display area 20, or it can be set intermittently, that is, set only in the area where the light-blocking component B is located. This invention does not impose any limitations.

[0063] Optional, such as Figures 13-15 As shown, Figure 13 This is a top view schematic diagram of another second display panel provided in an embodiment of the present invention. Figure 14 for Figure 13 Enlarged view of area S' on the second display panel. Figure 15 for Figure 3 The first display panel and Figure 13 A cross-sectional schematic diagram of the second display panel along section line A-A'; wherein the light-shielding layer M can be a second black matrix 221. Optionally, a light-blocking component B and a second black matrix 221 are provided at the connection part PEC of the pixel electrode PE. On the one hand, this avoids the light-blocking component B causing uneven brightness in the light-transmitting area of ​​the display module 00. Reusing the second black matrix 221 as the shielding layer M can avoid additional manufacturing processes and save costs. On the other hand, it can block less brightness when viewed directly and further reduce visibility when viewed obliquely to a certain extent, thereby ensuring a better display effect while ensuring the viewing angle requirements of the display module 00.

[0064] Optionally, the light-blocking component B is elongated, with its extension direction and arrangement direction intersecting. The light-blocking component B can be made of black photoresist material or other materials containing carbon black. For example... Figure 15As shown, the light-blocking component B can be disposed on the second opposing substrate 22 of the second display panel 2. The second opposing substrate 22 includes a second black matrix 221, an optical planarization layer 222, and the light-blocking component B, wherein the light-blocking component B is disposed on the side of the optical planarization layer 222 away from the second black matrix 221. In the direction perpendicular to the display module 00, the thickness of the light-blocking component B can be greater than that of the second black matrix 221.

[0065] Optional, such as Figures 16-17 , Figure 16 for Figure 3 The first display panel and Figure 4 Another cross-sectional view of the second display panel along section line A-A'. Figure 17 for Figure 3 The first display panel and Figure 4 Another cross-sectional view of the second display panel along section line A-A'; the light-blocking component B can be disposed on the second array substrate 21 of the second display panel 2. The second array substrate 21 includes a second substrate 22, and a film layer containing driving transistors, a second planarization layer 212, a second common electrode layer 213, a spacer insulating layer 214, and a second driving electrode layer 215 sequentially disposed on one side of the second substrate 22. The light-blocking component B can be disposed between the second planarization layer 212 and the second substrate 210, or it can be disposed on the side of the second planarization layer 212 away from the second substrate 210, that is, the light-blocking component B can be disposed below the second planarization layer 212 or above the second planarization layer 212. The light-blocking component B is disposed on the second array substrate 21 so that when light passes through the second array substrate 21, it is immediately blocked at a specific angle. In other words, the arrangement direction of the light-blocking component B can be shielded, which helps to reduce the viewing angle of the light passing through the display module 00 earlier. The light-blocking component B is located below the second planarization layer 212, which can be used to flatten the patterned film layer where the light-blocking component B is located, thereby avoiding obvious unevenness on the surface of the second array substrate 21. This is beneficial to the uniformity of the cell thickness of the second array substrate 21, thus ensuring the uniformity of the display of the display module 00. The light-blocking component B is located above the second planarization layer 212, that is, it is usually located on the same layer as the second driving electrode layer 215, thereby avoiding affecting the preparation of other film layers of the second array substrate 2 and avoiding unnecessary impact on the driving of the second array substrate 2. Thus, while ensuring the viewing angle requirements of the display module 00, a better display effect is guaranteed.

[0066] Optional, such as Figures 18-19 As shown, Figure 18 This is a top view schematic diagram of yet another second display panel provided in an embodiment of the present invention. Figure 19 for Figure 3 The first display panel and Figure 19A schematic cross-sectional view of the second display panel along section line A-A'; the light-blocking component B includes multiple segments forming a stepped shape. Figure 18 This invention uses three sections as an example, but the specific number of sections is not limited. This part can be set according to specific viewing requirements and process capabilities. Multiple sections are arranged sequentially along the first direction X. Figure 18 Taking the first direction X as the extension direction of the first scan line as an example, in other embodiments of the present invention, the first direction X can also be the extension direction of the first data line. In the direction Z perpendicular to the display module O0, the height of multiple portions gradually changes, for example... Figure 18 and Figure 19 As shown, the required viewing angle range for the left side of display module 00 is greater than that for the right side, meaning the left oblique viewing range is greater than the right oblique viewing range. Therefore, the height of the portion closer to the left side of display module 00 can be set lower than the height of the portion closer to the right side of display module 00; thus, the viewing angle requirements for different positions of display module 00 can be met. Optionally, the fabrication of these multiple portions can be achieved using a halftone mask in a single photolithography process, thereby simplifying the process and reducing costs.

[0067] This invention also provides a display device 01, which includes the aforementioned liquid crystal display module 00 and backlight module 3. When the first display panel 1 includes a touch electrode TP, the touch electrode TP can be built into the first display panel 1 or disposed on the light-emitting side of the first display panel 1. In this case, the first display panel 1 is located on the side of the second display panel 2 away from the backlight module 3, thereby avoiding the influence of the second display panel 2 on the touch electrode TP and ensuring touch sensitivity. Alternatively, when the second display panel 2 includes a touch electrode TP, in order to ensure touch sensitivity, the second display panel 2 needs to be located on the side of the first display panel 1 away from the backlight module 2. In this case, the resolution of the second display panel 2 needs to be consistent with the resolution of the first display panel 1 to ensure normal display of the display device 01. The liquid crystal display module 00 can be applied to in-vehicle display terminal products. The display device includes the aforementioned display panel, and the beneficial effects produced by the display device are as described in the above embodiments, and will not be repeated here.
