Display module and display device

Abstract

The present application relates to the technical field of display, and discloses a display module and a display device. The display module comprises a display panel and a first light adjusting structure. The first light adjusting structure has a great height, and may be located between a privacy pixel region and a shared pixel region of a privacy display region in the display panel and between adjacent privacy light-emitting regions, to limit the emergent light angle of light emitted from privacy light-emitting regions, thereby improving a display effect of the display module in a privacy mode. In addition, by arranging no first light adjusting structure between adjacent shared light-emitting regions of the privacy display region in the display panel, the influence of the first light adjusting structure on the emergent light angle of the shared light-emitting regions can be avoided, thereby ensuring a display effect of the display module in a shared display mode.

Display module and display device TECHNICAL FIELD

[0002] With the wider application of display devices, the privacy of display devices is gradually valued. Organic light-emitting diode (OLED) is a display screen technology.

[0123] For the purpose of making the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0124] FIG. 1 is a schematic view of a display module according to the related art. Referring to FIG. 1, the display module includes a display panel and a light modulation pattern. The display panel includes a plurality of light emitting regions arranged at intervals.

[0125] Referring to FIG. 1, the orthographic projection of the light modulation pattern on the display panel is located between adjacent light emitting regions. Some of the light emitted by the light emitting regions (such as the light indicated by the dashed line) can be absorbed by the light modulation pattern, while most of the light emitted by the light emitting regions (such as the light indicated by the solid line) cannot be absorbed by the light modulation pattern. That is, some light with a large viewing angle among the light emitted by the light emitting regions in the display module cannot be absorbed by the light modulation pattern and is emitted, thereby resulting in poor privacy function of the display module and poor effect of the privacy display of the display module.

[0126] FIG. 2 is a schematic view of a display module according to an embodiment of the present application. Referring to FIG. 2, the display module 100 includes a display panel 101 and a first light modulation structure 102. The display panel 101 includes a substrate 1011, and a driving circuit layer 1012 and a light emitting device layer 1013 arranged in layers on one side of the substrate 1011. The driving circuit layer 1012 and the light emitting device layer 1013 are electrically connected.

[0127] FIG. 3 is a partial top view of a display module according to an embodiment of the present application. In combination with FIGS. 2 and 3, the display panel 101 has a privacy display area 101a. The privacy display area 101a includes a privacy pixel area 101a1 and a shared pixel area 101a2. The privacy pixel area 101a1 includes a plurality of privacy light emitting regions F1, and the shared pixel area 101a2 includes a plurality of shared light emitting regions F2. Each of the plurality of privacy light emitting regions F1 and the plurality of shared light emitting regions F2 is configured to emit light.

[0128] In combination with FIG. 2 and FIG. 3, the first light adjusting structure 102 is located on one side of the substrate 1011. The orthographic projection of the first light adjusting structure 102 on the substrate 1011 is located between the peep-proof pixel area 101a1 and the shared pixel area 101a2, between the orthographic projection of the adjacent peep-proof light-emitting region F1 on the substrate 1011, and not between the orthographic projection of the adjacent shared light-emitting region F2 on the substrate 1011. In FIG. 2, the first light adjusting structure 102 is located on the side of the display panel 101 away from the substrate 1011. FIG. 2 can be a cross-sectional view of FIG. 3 along the direction of AA'.

[0129] In the first light adjusting structure 102, at least part of the height of the portion close to the peep-proof light-emitting region is greater than the height threshold, and the first light adjusting structure 102 is used to modulate the angle of the light emitted by the peep-proof light-emitting region.

[0130] In the embodiments of the present application, the display mode of the display module 100 can include a peep-proof display mode and a shared display mode. When the display mode of the display module 100 is set to the peep-proof display mode, the peep-proof light-emitting region F1 in the display module can be used to emit light, and the shared light-emitting region F2 does not need to emit light. When the display mode of the display module 100 is set to the shared display mode, the shared light-emitting region F2 in the display module can be used to emit light, and the peep-proof light-emitting region F1 can emit light or not emit light.

[0131] Since the orthographic projection of the first light adjusting structure 102 on the substrate 1011 is located between the peep-proof pixel area 101a1 and the shared pixel area 101a2, and between the orthographic projection of the adjacent peep-proof light-emitting region F1 on the substrate 1011, the light of a certain viewing angle emitted by the peep-proof light-emitting region F1 can be absorbed by the first light adjusting structure 102. Moreover, since the height H1 of at least part of the portion of the first light adjusting structure 102 close to the peep-proof light-emitting region F1 is greater than the height threshold, the height H1 of at least part of the portion of the first light adjusting structure 102 close to the peep-proof light-emitting region F1 can be made higher, so that the light of a larger viewing angle emitted by the peep-proof light-emitting region F1 can be absorbed by the first light adjusting structure 102. Thus, when the display mode of the display module 100 is the peep-proof display mode, the first light adjusting structure 102 can limit the light-emitting angle of the light emitted by the peep-proof light-emitting region F1, and the display effect of the display module 100 in the peep-proof mode is improved.

[0132] And, since the orthogonal projection of the first light ray light adjusting structure 102 on the substrate 1011 is not located between the orthogonal projections of the adjacent shared light emitting areas F2 on the substrate 1011, the first light ray light adjusting structure 102 can avoid affecting the light emitting angle of the shared light emitting area F2, and ensure the display effect of the display module 100 in the shared display mode.

[0133] In summary, the display module provided by the embodiments of the present application includes a display panel and a first light ray light adjusting structure. The first light ray light adjusting structure has a high height, and can be located between the privacy pixel area and the shared pixel area of the privacy display area in the display panel, and between the adjacent privacy light emitting areas, for limiting the light emitting angle of the light emitted by the privacy light emitting area, and improving the display effect of the display module in the privacy mode. In addition, no first light ray light adjusting structure is arranged between the adjacent shared light emitting areas in the privacy display area in the display panel, which can avoid affecting the light emitting angle of the shared light emitting area, and ensure the display effect of the display module in the shared display mode.

[0134] Optionally, the height threshold can be greater than or equal to 3 μm (micrometer). For example, the height threshold can be 5 μm, 10 μm, 13 μm, 15 μm, 20 μm, 25 μm, 30 μm, etc.

[0135] In the embodiments of the present application, the light emitting device layer 1013 can include a plurality of light emitting pixels. The plurality of light emitting pixels can include red light emitting pixels (red, R), green light emitting pixels (green, G), and blue light emitting pixels (blue, B). The red light emitting pixels R can be used to emit red light, the green light emitting pixels G can be used to emit green light, and the blue light emitting pixels B can be used to emit blue light. Optionally, the light emitting pixels can be organic light emitting diodes (OLED).

[0136] Optionally, one red light emitting pixel R, one green light emitting pixel G, and one blue light emitting pixel B can constitute a pixel unit. Of course, the number of red light emitting pixels, green light emitting pixels, and blue light emitting pixels included in the pixel unit is not limited in the embodiments of the present application. For example, one pixel unit can include one red light emitting pixel, two green light emitting pixels, and one blue light emitting pixel.

[0137] Optionally, the arrangement mode of the light emitting pixels in the display module 100 can be as shown in FIG. 4. Alternatively, the arrangement mode of the light emitting pixels in the display module can be as shown in FIG. 5. Alternatively, the arrangement mode of the light emitting pixels in the display module can be other arrangement modes, such as diamond arrangement, etc.

[0138] In the embodiments of the present application, in order to realize the peep-proof and sharing of the display module, the light-emitting pixels included in the display module can have the following two design schemes.

[0139] In scheme one, referring to FIG. 6, each light-emitting pixel is segmented to obtain peep-proof sub-pixels and sharing sub-pixels. The light-emitting area of the peep-proof sub-pixel is a peep-proof light-emitting area, and the light-emitting area of the sharing sub-pixel is a sharing light-emitting area. In the case where the display mode of the display module 100 is set to the peep-proof display mode, only the peep-proof sub-pixels can be lit. In the case where the display mode of the display module 100 is set to the sharing display mode, the sharing sub-pixels can be lit, and the peep-proof sub-pixels can be lit or not. The red light-emitting pixel R in FIG. 6 includes a red peep-proof sub-pixel R1 and a red sharing sub-pixel R2. The green light-emitting pixel G includes a green peep-proof sub-pixel G1 and a green sharing sub-pixel G2. The blue light-emitting pixel B includes a blue peep-proof sub-pixel B1 and a blue sharing sub-pixel B2.

[0140] In scheme two, referring to FIG. 7, the light-emitting pixels are pixel-partitioned, and the light-emitting pixels located in the peep-proof pixel area 101a1 can be peep-proof pixels, and the light-emitting pixels located in the sharing pixel area 101a2 can be sharing pixels. The light-emitting area of the peep-proof pixel is a peep-proof light-emitting area, and the light-emitting area of the sharing pixel is a sharing light-emitting area. In the case where the display mode of the display module 100 is set to the peep-proof display mode, only the peep-proof pixels can be lit. In the case where the display mode of the display module 100 is set to the sharing display mode, the sharing pixels can be lit, and the peep-proof pixels can be lit or not. The red light-emitting pixel Ra in FIG. 7 is a red peep-proof pixel, and the red light-emitting pixel Rb is a red sharing pixel. The green light-emitting pixel Ga is a green peep-proof pixel, and the green light-emitting pixel Gb is a green sharing pixel. The blue light-emitting pixel Ba is a blue peep-proof pixel, and the blue light-emitting pixel Bb is a blue sharing pixel.

[0141] FIG. 3 can be a design schematic diagram of the arrangement of the light-emitting pixels in the display module 100 in FIG. 4, and the peep-proof pixel area 101a1 and the sharing pixel area 101a2 obtained by segmenting the light-emitting pixels. Referring to FIG. 3, the peep-proof display area 101a includes a plurality of peep-proof pixel areas 101a1 extending along the first direction X and arranged along the second direction Y, and a plurality of sharing pixel areas 101a2 extending along the first direction X and arranged along the second direction Y. The plurality of peep-proof pixel areas 101a1 and the plurality of sharing pixel areas 101a2 are staggered. The second direction Y and the first direction X intersect. For example, the second direction Y and the first direction X are perpendicular. The first direction X is the pixel row direction of the display module 100, and the second direction Y is the pixel column direction of the display module.

[0142] Optionally, referring to FIG. 2, the light-emitting pixel can include a shared sub-pixel located in the shared pixel region 101a2 and a privacy sub-pixel located in the privacy pixel region 101a1. The privacy sub-pixel can be further divided into two smaller privacy micro-pixels arranged along the first direction X. In this case, the light-emitting region of the privacy sub-pixel can include two light-emitting regions arranged along the first direction X, and the two light-emitting regions correspond to the two privacy micro-pixels. The light-emitting region of each privacy micro-pixel can be a privacy light-emitting region.

[0143] FIG. 8 is a partial top view of another display module according to an embodiment of the present application. As shown in FIG. 8, the privacy display region includes a plurality of privacy pixel regions 101a1 extending along the first direction X and arranged along the second direction Y, and a plurality of shared pixel regions 101a2 extending along the first direction X and arranged along the second direction Y.

[0144] Referring to FIG. 8, the light-emitting pixel can include a shared sub-pixel located in the shared pixel region 101a2 and a privacy sub-pixel located in the privacy pixel region 101a1. The privacy sub-pixel can be further divided into two smaller privacy micro-pixels arranged along the second direction Y. In this case, the light-emitting region of the privacy sub-pixel can include two light-emitting regions arranged along the second direction Y, and the two light-emitting regions correspond to the two privacy micro-pixels. The light-emitting region of each privacy micro-pixel can be a privacy light-emitting region.

[0145] It can be understood that FIG. 3 and FIG. 8 are privacy micro-pixels arranged along different directions obtained by dividing the privacy sub-pixel of the light-emitting pixel along different directions. Specifically, FIG. 3 can be used to represent two privacy micro-pixels arranged along the first direction X obtained by dividing the privacy sub-pixel along the second direction Y, and FIG. 8 can be used to represent two privacy micro-pixels arranged along the second direction Y obtained by dividing the privacy sub-pixel along the first direction X.

[0146] It can be understood that the shared sub-pixel of the light-emitting pixel in FIG. 3 and FIG. 8 is not further divided into a plurality of shared micro-pixels. Therefore, on the second direction Y, both sides of the shared sub-pixel of the light-emitting pixel are the privacy sub-pixels. The first light ray adjusting structure 102 can be located between the shared light-emitting region of the shared sub-pixel and the privacy light-emitting region of the privacy sub-pixel. Therefore, FIG. 3 and FIG. 8 can be understood as that the first light ray adjusting structure 102 is arranged on both sides of the shared sub-pixel of the light-emitting pixel on the second direction Y.

[0147] In the embodiment of the present application, referring to FIG. 9, the red light-emitting pixel R can be divided into one red shared sub-pixel R2 and one red anti-peep sub-pixel R1, and the corresponding red light-emitting pixel R has one red shared light-emitting area RF2 and one red anti-peep light-emitting area RF1. The green light-emitting pixel G can be divided into one green shared sub-pixel G2 and one green anti-peep sub-pixel G1, and the corresponding green light-emitting pixel G has one green shared light-emitting area GF2 and one green anti-peep light-emitting area GF1. The blue light-emitting pixel B can be divided into one blue shared sub-pixel B2 and one blue anti-peep sub-pixel B1, and the corresponding blue light-emitting pixel B has one blue shared light-emitting area BF2 and one blue anti-peep light-emitting area BF1.

[0148] In the scheme shown in FIG. 9, neither the shared sub-pixel nor the anti-peep sub-pixel obtained by dividing the light-emitting pixel is further divided into smaller micro-pixels.

[0149] Alternatively, referring to FIG. 10, the red light-emitting pixel R is divided into one red shared sub-pixel R2 and one red anti-peep sub-pixel R1, and the red anti-peep sub-pixel R1 can be divided into two red anti-peep micro-pixels R11, and the corresponding red light-emitting pixel has one red shared light-emitting area RF2 and two red anti-peep light-emitting areas RF1. The green light-emitting pixel G can be divided into one green shared sub-pixel G2 and one green anti-peep sub-pixel G1, and the green shared sub-pixel G2 can be divided into two strip-shaped green shared micro-pixels G21, and the green anti-peep sub-pixel G1 can be divided into four green anti-peep micro-pixels G11. The corresponding green light-emitting pixel G has two green shared light-emitting areas GF2 and four green anti-peep light-emitting areas GF1. The blue light-emitting pixel B can be divided into one blue shared sub-pixel B2 and one blue anti-peep sub-pixel B1, and the blue shared sub-pixel B2 can be divided into three strip-shaped blue shared micro-pixels B21, and the blue anti-peep sub-pixel B1 can be divided into six blue anti-peep micro-pixels B11. The corresponding blue light-emitting pixel B has three blue shared light-emitting areas BF2 and six blue anti-peep light-emitting areas BF1.

[0150] In the scheme shown in FIG. 10, the shared sub-pixel R2 obtained by dividing the red light-emitting pixel R is not further divided into smaller micro-pixels, and the anti-peep sub-pixel R1 obtained by dividing the red light-emitting pixel R is further divided into smaller anti-peep micro-pixels R11. The shared sub-pixel and the anti-peep sub-pixel of the green light-emitting pixel G and the blue light-emitting pixel B are all further divided into smaller micro-pixels.

[0151] Alternatively, referring to FIG. 11, the red light-emitting pixel R is divided into one red shared sub-pixel R2 and one red privacy sub-pixel R1, and the red privacy sub-pixel R1 can be divided into ten red privacy micro-pixels R11. The corresponding red light-emitting pixel R has one red shared light-emitting area RF2 and ten red privacy light-emitting areas RF1. The green light-emitting pixel G can be divided into one green shared sub-pixel G2 and one green privacy sub-pixel G1, and the green privacy sub-pixel G1 can be divided into four green privacy micro-pixels G11. The corresponding green light-emitting pixel G has one green shared light-emitting area GF2 and four green privacy light-emitting areas GF1. The blue light-emitting pixel B can be divided into one blue shared sub-pixel B2 and one blue privacy sub-pixel B1, and the blue privacy sub-pixel B1 can be divided into 12 blue privacy micro-pixels B11. The corresponding blue light-emitting pixel B has one blue shared light-emitting area BF2 and 12 blue privacy light-emitting areas BF1.

[0152] In the scheme shown in FIG. 11, the shared sub-pixels obtained by dividing the light-emitting pixels are not further divided into smaller shared micro-pixels, and the privacy sub-pixels of the light-emitting pixels are all further divided into smaller privacy micro-pixels.

[0153] Generally, the area of the orthographic projection of each privacy light-emitting area F1 on the substrate 1011 can be smaller than the area of the orthographic projection of one shared light-emitting area F2 on the substrate 1011, and the number of the privacy light-emitting areas F1 can be greater than the number of the shared light-emitting areas F2.

[0154] Optionally, the number of the privacy light-emitting areas of the light-emitting pixel (or the number of the privacy micro-pixels obtained by dividing the privacy sub-pixels of the light-emitting pixel) can be related to the arrangement of the light-emitting pixel, and the number of the privacy micro-pixels obtained by dividing the privacy sub-pixels of the light-emitting pixel is not limited in the embodiments of the present application.

[0155] For example, in FIG. 11, for the red light-emitting pixel R, the number of the privacy micro-pixels obtained by dividing the privacy sub-pixels of the red light-emitting pixel R can range from 6 to 15 (10 in FIG. 11); for the green light-emitting pixel G, the number of the privacy micro-pixels obtained by dividing the privacy sub-pixels of the green light-emitting pixel G can range from 2 to 8 (4 in FIG. 11); and for the blue light-emitting pixel B, the number of the privacy micro-pixels obtained by dividing the privacy sub-pixels of the blue light-emitting pixel B can range from 8 to 20 (12 in FIG. 11).

[0156] Referring to FIGS. 10 and 11, the area of the orthographic projection of the light emitting region (including the blue shared light emitting region and the blue privacy light emitting region) of the blue light emitting pixel B on the substrate substrate 1011 is greater than the area of the orthographic projection of the light emitting region (including the green shared light emitting region and the green privacy light emitting region) of the green light emitting pixel G on the substrate substrate 1011. The area of the orthographic projection of the light emitting region (including the green shared light emitting region and the green privacy light emitting region) of the green light emitting pixel G on the substrate substrate 1011 is greater than the area of the orthographic projection of the light emitting region (including the red shared light emitting region and the red privacy light emitting region) of the red light emitting pixel R on the substrate substrate 1011.

[0157] Alternatively, the area of the orthographic projection of the light emitting region (including the blue shared light emitting region and the blue privacy light emitting region) of the blue light emitting pixel B on the substrate substrate 1011, the area of the orthographic projection of the light emitting region (including the green shared light emitting region and the green privacy light emitting region) of the green light emitting pixel G on the substrate substrate 1011, and the area of the orthographic projection of the light emitting region (including the red shared light emitting region and the red privacy light emitting region) of the red light emitting pixel R on the substrate substrate 1011 can have at least two areas that are the same. The present application does not specifically limit the size relationship of the area of the orthographic projection of the light emitting region of the blue light emitting pixel B on the substrate substrate 1011, the area of the orthographic projection of the light emitting region of the green light emitting pixel G on the substrate substrate 1011, and the area of the orthographic projection of the light emitting region of the red light emitting pixel R on the substrate substrate 1011.

[0158] Further, the number of blue privacy light emitting regions that the blue light emitting pixel B has can be greater than the number of green privacy light emitting regions that the green light emitting pixel G has. The number of green privacy light emitting regions that the green light emitting pixel G has can be greater than the number of red privacy light emitting regions that the red light emitting pixel R has.

[0159] For example, referring to FIG. 10, the number of blue privacy light emitting regions BF1 that the blue light emitting pixel B has (6) is greater than the number of green privacy light emitting regions GF1 that the green light emitting pixel G includes (4). The number of green privacy light emitting regions GF1 that the green light emitting pixel G includes is greater than the number of red privacy light emitting regions RF1 that the red light emitting pixel R includes (2).

[0160] Alternatively, referring to FIG. 11, the number of blue privacy light emitting regions BF1 that the blue light emitting pixel B has (12) is greater than the number of green privacy light emitting regions GF1 that the green light emitting pixel G includes (10). The number of green privacy light emitting regions GF1 that the green light emitting pixel G includes is greater than the number of red privacy light emitting regions RF1 that the red light emitting pixel R includes (4).

[0161] Of course, there can be at least two of the number of blue anti-peep light-emitting regions of the blue light-emitting pixels B, the number of green anti-peep light-emitting regions of the green light-emitting pixels G, and the number of red anti-peep light-emitting regions of the red light-emitting pixels R are the same. Embodiments of the present application do not make specific restrictions on the number of blue anti-peep light-emitting regions of the blue light-emitting pixels B, the number of green anti-peep light-emitting regions of the green light-emitting pixels G, and the number of red anti-peep light-emitting regions of the red light-emitting pixels R.

[0162] In addition, the number of blue shared light-emitting regions of the blue light-emitting pixels B can be greater than the number of green shared light-emitting regions of the green light-emitting pixels G. The number of green shared light-emitting regions of the green light-emitting pixels G can be greater than the number of red shared light-emitting regions of the red light-emitting pixels R.

[0163] For example, referring to FIG. 10, the number of blue shared light-emitting regions BF2 included in the blue light-emitting pixels B (3) is greater than the number of green shared light-emitting regions GF2 included in the green light-emitting pixels G (2). The number of green shared light-emitting regions GF2 included in the green light-emitting pixels G is greater than the number of red shared light-emitting regions RF2 included in the red light-emitting pixels R (1).

[0164] Of course, there can be at least two of the number of blue shared light-emitting regions of the blue light-emitting pixels B, the number of green shared light-emitting regions of the green light-emitting pixels G, and the number of red shared light-emitting regions of the red light-emitting pixels R are the same. For example, in FIG. 11, the number of blue shared light-emitting regions of the blue light-emitting pixels B, the number of green shared light-emitting regions of the green light-emitting pixels G, and the number of red shared light-emitting regions of the red light-emitting pixels R are all the same (all 1). Embodiments of the present application do not make specific restrictions on the number of blue shared light-emitting regions of the blue light-emitting pixels B, the number of green shared light-emitting regions of the green light-emitting pixels G, and the number of red shared light-emitting regions of the red light-emitting pixels R.

[0165] For the scheme of dividing the light-emitting pixels to obtain anti-peep sub-pixels and shared sub-pixels, the anti-peep pixel area 101a1 can be an area where the anti-peep sub-pixels of multiple light-emitting pixels are located, and the shared pixel area 101a2 can be an area where the shared sub-pixels of multiple light-emitting pixels are located. FIG. 12 is a partial top view of another display module provided by an embodiment of the present application. As can be seen from FIG. 12, the anti-peep pixel area 101a1 can be a strip-shaped area extending along the first direction X, and the shared pixel area 101a2 can be a strip-shaped area extending along the first direction X.

[0166] Referring to FIG. 7, the way of partitioning the light-emitting pixels obtains the scheme of the privacy pixels and the shared pixels, each privacy pixel area 101a1 can be a rectangular area, and each privacy pixel area 101a1 can include one pixel unit (which can include one red light-emitting pixel R, one green light-emitting pixel G and one blue light-emitting pixel B). Each shared pixel area 101a2 can also be a rectangular area, and each shared pixel area 101a2 can include one pixel unit (which can include one red light-emitting pixel R, one green light-emitting pixel G and one blue light-emitting pixel B).

[0167] It should be noted that each privacy pixel area 101a1 can also include a plurality of pixel units, and each shared pixel area 101a2 can also include a plurality of pixel units. The number of pixel units included in the privacy pixel area 101a1 and the shared pixel area 101a2 is not limited in the embodiments of the present application.

[0168] It should be further noted that the shape of the privacy pixel area 101a1 and the shared pixel area 101a2 is not limited in the embodiments of the present application, which can be a strip shape as shown in FIG. 12, or a rectangular shape as shown in FIG. 7, or a polyline shape, a curve shape or any other possible shape.

[0169] In the embodiments of the present application, the shape of the privacy light-emitting area F1 included in each light-emitting pixel 10131 can be a square, a hexagon, an octagon, a rhombus, a polygon, a circle, a circle-like shape or an ellipse, etc. The shape of the privacy light-emitting area is not limited in the embodiments of the present application. For example, the shape of the privacy light-emitting area in FIGS. 10 and 11 is a circle.

[0170] In the embodiments of the present application, no matter how the privacy light-emitting area F1 and the shared light-emitting area F2 are arranged, the first light ray modulation structure 102 can be arranged between the privacy pixel area 101a1 and the shared pixel area 101a2 and between any two adjacent privacy light-emitting areas F1, so that the first light ray modulation structure 102 modulates the light-emitting angle of the privacy light-emitting area F1, and ensures the display effect of the display module 100 in the privacy mode.

[0171] In the embodiment of the present application, FIG. 13 is a sectional view of FIG. 3 along the direction of BB'. Referring to FIG. 13, the display module 100 further comprises a second light adjusting structure 103 located on one side of the substrate 1011. The orthogonal projection of the second light adjusting structure 103 on the substrate 1011 is between the orthogonal projections of adjacent shared light emitting areas F2 on the substrate 1011. The height of the second light adjusting structure 103 is less than the height of at least part of the first light adjusting structure 102 close to the privacy light emitting area F1, and the second light adjusting structure 103 is used for modulating the angle of the light emitted by the shared light emitting area F2. In FIG. 13, the second light adjusting structure 103 is also located on the side of the light emitting device layer 1013 of the display panel 101 away from the substrate 1011.

[0172] In the embodiment of the present application, the height H2 of the second light adjusting structure 103 is less than the height H1 of the first light adjusting structure 102, so the viewing angle range of the light that can be absorbed by the second light adjusting structure 103 is less than the viewing angle range of the light that can be absorbed by the first light adjusting structure 102. In this way, not only can light crosstalk between different shared light emitting areas F2 be avoided, but also the second light adjusting structure 103 can avoid affecting the light emitted by the shared light emitting area F2, thereby ensuring the display effect of the display module 100 in the shared display mode.

[0173] Referring to FIGS. 2 and 13, the display module 100 further comprises a protective layer 104 located on the side of the light emitting device layer 1013 of the display panel 101 away from the substrate 1011. The orthogonal projection of the protective layer 104 on the substrate 1011 can overlap the orthogonal projection of the light emitting area (the privacy light emitting area F1 or the shared light emitting area F2) on the substrate 1011. Part of the light emitted by the privacy light emitting area F1 is absorbed by the first light adjusting structure 102, and the light emitted by the privacy light emitting area F1 that is not absorbed by the first light adjusting structure 102 can first enter the protective layer 104 and then exit the protective layer 104. Part of the light emitted by the shared light emitting area F2 is absorbed by the second light adjusting structure 103, and the light emitted by the shared light emitting area F2 that is not absorbed by the second light adjusting structure 103 can first enter the protective layer 104 and then exit the protective layer 104.

[0174] Referring to FIG. 13, the protective layer 104 can cover the second light adjusting structure 103 and expose the first light adjusting structure 102. In this case, the first light adjusting structure 102, the second light adjusting structure 103, and the protective layer 104 can be prepared by forming a light adjusting film, patterning the light adjusting film by using a mask to obtain at least part of the first light adjusting structure 102 and the second light adjusting structure 103, forming a protective film on the at least part of the first light adjusting structure 102 and the second light adjusting structure 103 away from the substrate 1011, patterning the protective film by using a mask to obtain an opening, filling the opening with a light adjusting material, and forming the first light adjusting structure 102 with the light adjusting material and the at least part of the first light adjusting structure 102 exposed by the opening. The patterning process includes photoresist coating, exposure, development, etching, and photoresist removal.

[0175] Alternatively, the first light adjusting structure 102, the second light adjusting structure 103, and the protective layer 104 can be prepared by forming a light adjusting film, patterning the light adjusting film by using a mask to obtain the second light adjusting structure 103, forming a protective film on the second light adjusting structure 103 away from the substrate 1011, patterning the protective film by using a mask, and filling the opening with a light adjusting material to form the first light adjusting structure 102.

[0176] In the above two preparation methods, to obtain the first light adjusting structure 102 with a high height, the protective film can be formed to have a large thickness. In this way, the opening of the protective film can have a large depth, and the first light adjusting structure 102 with a high height can be obtained after the opening is filled with the light adjusting material.

[0177] Alternatively, the first light adjusting structure 102, the second light adjusting structure 103, and the protective layer 104 can be prepared by forming a light adjusting film, patterning the light adjusting film by using a mask to obtain the second light adjusting structure 103, forming a protective film on the second light adjusting structure 103 away from the substrate 1011, patterning the protective film by using a mask, and filling the opening with a light adjusting material to form the first light adjusting structure 102.

[0178] Alternatively, the preparation method of the first light adjusting structure 102, the second light adjusting structure 103 and the protective layer 104 can include: forming a first light adjusting film; performing a patterning process on the first light adjusting film by using a first mask to obtain a part of the first light adjusting structure 102 and the second light adjusting structure 103; forming a second light adjusting film; performing a patterning process on the second light adjusting film by using a second mask to obtain another part of the first light adjusting structure 102, and the part and the other part of the first light adjusting structure 102 together constitute the first light adjusting structure 102; and filling a protective material between the first light adjusting structure 102 and the second light adjusting structure 103 and on a side of the second light adjusting structure 103 away from the substrate 1011 to obtain the protective layer 104.

[0179] Optionally, the material of the protective layer 104 can be optical clear adhesive (OC). Alternatively, in order to enable the protective layer 104 to reduce the reflection of light, the protective layer 104 can also be referred to as a reflection adjustment layer, and the material of the reflection adjustment layer can be gray optical clear adhesive (gray OC).

[0180] Optionally, the reflection adjustment layer can selectively absorb light of some wavelength bands from the reflection of the display module or the incidence of light from the outside of the display module. Optionally, the reflection adjustment layer can absorb light of a first wavelength band of about 480 nm to about 500 nm, and absorb light of a second wavelength band of about 585 nm to about 605 nm. The light transmittance spectrum of the reflection adjustment layer can have a light transmittance of 40% or less in the first wavelength band and the second wavelength band. The reflection adjustment layer can absorb light of a wavelength deviating from the emission wavelength range of red, green or blue of the OLED.

[0181] In the embodiment of the present application, referring to FIG. 14, the first light adjusting structure 102 can include a first light adjusting part 1021 and a second light adjusting part 1022. The first light adjusting part 1021 is located on a side of the light emitting device layer 1013 of the display panel 101 away from the substrate 1011, the protective layer 104 (the reflection adjustment layer) is located on a side of the first light adjusting part 1021 away from the substrate 1011, and the second light adjusting part 1022 is located on a side of the protective layer 104 away from the substrate 1011. The height of the first light adjusting structure 102 can refer to the sum of the heights of the first light adjusting part 1021 and the second light adjusting part 1022.

[0182] Optionally, the orthographic projection of the first light adjusting part 1021 on the substrate 1011 and the orthographic projection of the second light adjusting part 1022 on the substrate 1011 at least partially overlap. For example, the orthographic projection of the first light adjusting part 1021 on the substrate 1011 and the orthographic projection of the second light adjusting part 1022 on the substrate 1011 overlap.

[0183] Optionally, referring to FIG. 14, the first light-adjusting portion 1021 and the second light-adjusting portion 1022 of the first light-adjusting structure 102 can be embedded in the protective layer 104. Such a design can reduce the overall thickness of the display module 100, facilitating the production of a light and thin product. The display module 100 shown in FIG. 14 does not have the second light-adjusting structure 103.

[0184] For example, the surface of the first light-adjusting portion 1021 close to the substrate 1011 can be coplanar with the surface of the protective layer 104 close to the substrate 1011, and the surface of the second light-adjusting portion 1022 away from the substrate 1011 can be coplanar with the surface of the protective layer 104 away from the substrate 1011. The thickness of the part of the protective layer 104 located in the region where the first light-adjusting portion 1021 and the second light-adjusting portion 1022 are located can be equal to the sum of the thickness of the first light-adjusting portion 1021 and the thickness of the second light-adjusting portion 1022.

[0185] For the display module shown in FIG. 14, the preparation method of the first light-adjusting structure 102 and the protective layer 104 can include: forming a first light-adjusting film; using a mask to patternize the first light-adjusting film to obtain the first light-adjusting portion 1021 of the first light-adjusting structure 102; forming a protective film; using a mask to patternize the protective film to obtain an opening, so that the orthographic projection of the opening on the substrate 1011 and the orthographic projection of the first light-adjusting portion on the substrate 1011 overlap; and filling a light-adjusting material in the opening to obtain the second light-adjusting portion 1022 of the first light-adjusting structure 102.

[0186] FIG. 15 is a partial cross-sectional view of another display module provided by an embodiment of the present application. Referring to FIG. 15, the first light-adjusting structure 102 located between the peep-proof pixel region 101a1 and the shared pixel region 101a2 includes a first portion 1023 and a second portion 1024. The first portion 1023 is closer to the peep-proof light-emitting region F1 than the second portion 1024. The second portion 1024 is closer to the shared light-emitting region F2 than the first portion 1023. The thickness of the first portion 1023 is greater than the thickness of the second portion 1024. In the above-described embodiments, the at least part of the first light-adjusting structure 102 close to the peep-proof light-emitting region F1 can refer to the first portion 1023, and the height of the at least part of the first light-adjusting structure 102 close to the peep-proof light-emitting region F1 greater than the height threshold can refer to the height of the first portion 1023 greater than the height threshold.

[0187] Since the area where the privacy light-emitting region F1 and the shared light-emitting region F2 adjoin, if the thickness of the light-adjusting structure is set to be thicker, the light of the shared light-emitting region F2 will be blocked, and if the thickness of the light-adjusting structure is set to be thinner, the privacy effect of the privacy light-emitting region F1 will be poor. Therefore, the light-adjusting structure of the area where the privacy light-emitting region F1 and the shared light-emitting region F2 adjoin is designed as the first light-adjusting structure with height difference in the embodiment of the present application. The first part 1023 of the first light-adjusting structure is arranged close to the privacy light-emitting region F1, and can be used to absorb the light of the privacy light-emitting region F1. The second part 1024 of the first light-adjusting structure is arranged close to the shared light-emitting region F2, and can ensure the light of the shared light-emitting region F2 to exit.

[0188] Optionally, the height of the first part 1023 of the first light-adjusting structure 102 can be the same as the height H1 of the first light-adjusting structure 102 between the normal projection of the adjacent privacy light-emitting region F1 on the substrate 1011. The height of the second part 1024 of the first light-adjusting structure can be the same as the height H2 of the second light-adjusting structure 103.

[0210] In the embodiments of the present application, the privacy sub-pixel and the shared sub-pixel are obtained by segmenting the light-emitting pixel. Referring to FIGS. 17 and 18, the light-emitting pixel 10131 includes a privacy sub-pixel 101311 and a shared sub-pixel 101312. FIG. 18 is a sectional view of FIG. 17 along the direction of CC'. In order to achieve separate control of the privacy sub-pixel 101311 and the shared sub-pixel 101312, the anode patterns of the privacy sub-pixel 101311 and the shared sub-pixel 101312 can be arranged in a spaced manner. That is, the privacy sub-pixel 101311 includes an anode pattern m11, the shared sub-pixel 101312 includes an anode pattern m11, and the anode pattern m11 included in the privacy sub-pixel 101311 and the anode pattern m11 included in the shared sub-pixel 101312 are arranged in a spaced manner.

For example, referring to FIG. 18, the orthographic projection of the light-emitting pattern m31 on the substrate 1011 can cover the orthographic projection of the anode pattern m11 included in the privacy sub-pixel 101311 on the substrate 1011, and cover the orthographic projection of the anode pattern m11 included in the shared sub-pixel 101312 on the substrate 1011. In addition, the cathode layer m4 included in the plurality of light-emitting pixels 10131 of the light-emitting device layer 1013 can be a whole layer film layer shared by the plurality of light-emitting pixels 10131.

[0213] Optionally, referring to FIG. 19, the privacy sub-pixel 101311 can include a plurality of privacy micro-pixels 1013111, and the anode patterns m11 of the privacy micro-pixels 1013111 in the privacy sub-pixel 101311 are shared. That is, the anode patterns m11 of the plurality of privacy micro-pixels 1013111 obtained by dividing the privacy sub-pixel 101311 are continuous and unbroken, and the plurality of privacy light-emitting regions F1 can be obtained by setting the hollow region of the pixel defining layer and / or setting the first light shielding layer in the color filter assembly, and the plurality of privacy light-emitting regions F1 correspond to the plurality of privacy micro-pixels 1013111.

The light-emitting pattern m31 is connected by the privacy sub-hollow region L11 and the part of the anode pattern.

[0215] Referring to FIG. 19, the privacy hollow region L1 included in the pixel defining layer m2 can include two privacy sub-hollow regions L11, and each privacy sub-hollow region L11 exposes a part of the shared anode pattern. The light-emitting pattern m31 is connected by the privacy sub-hollow region L11 and the part of the anode pattern.

[0216] In the embodiments of the present application, the privacy sub-pixel and the shared sub-pixel are obtained by dividing the light-emitting pixel. Referring to FIG. 7, a part of the plurality of light-emitting pixels is located in the privacy pixel area 101a1, and another part of the plurality of light-emitting pixels is located in the shared pixel area 101a2. The light-emitting pixel located in the privacy pixel area 101a1 is the privacy sub-pixel, and the light-emitting region of the light-emitting pixel located in the privacy pixel area 101a1 is the privacy light-emitting region F1. The light-emitting pixel located in the shared pixel area 101a2 is the shared sub-pixel, and the light-emitting region of the light-emitting pixel located in the shared pixel area 101a2 is the shared light-emitting region F2.

[0217] FIG. 20 is a partial cross-sectional view of a kind of anti-peep pixel region provided in an embodiment of the present application. FIG. 20 shows two light-emitting pixels 101311 (anti-peep pixels). Referring to FIG. 20, the anode pattern of each anti-peep pixel is arranged in intervals (i.e., discontinuously arranged). Of course, in the shared pixel region 101a2, the anode pattern of each light-emitting pixel (shared pixel) is also arranged in intervals. That is, whether it is an anti-peep pixel or a shared pixel, each light-emitting pixel includes an anode pattern, and the anode patterns of multiple light-emitting pixels are arranged in intervals.

[0218] The multiple hollow regions of the pixel definition layer m2 include an anti-peep hollow region L1 that exposes at least part of the anode pattern of the anti-peep pixel, and a shared hollow region (not shown in FIG. 20) that exposes at least part of the anode pattern of the shared pixel.

The light-emitting pattern of the shared pixel is connected through the shared hollow region and at least part of the anode pattern of the shared pixel.

[0220] As can be seen from FIG. 20, the anti-peep pixels and the shared pixels are obtained by partitioning the light-emitting pixels, the anode pattern of the light-emitting pixels is discontinuously arranged in intervals, and the light-emitting pattern of the light-emitting pixels is also discontinuously arranged in intervals.

[0221] In an embodiment of the present application, the light-emitting device layer 1013 can further include an organic functional layer (not shown in the figure) between the cathode layer m4 and the anode layer m1. The organic functional layer can be a common whole film layer. The organic functional layer can include a hole injection layer, a hole transport layer, an electron transport layer, and an electrode injection layer, etc. The organic functional layer and the light-emitting layer m3 can be collectively referred to as an organic light-emitting functional layer. Part of the film layers in the organic functional layer can be located between the light-emitting layer m3 and the anode layer m1, and another part of the film layers can be located between the light-emitting layer m3 and the cathode layer m4.

[0222] In an embodiment of the present application, the anti-peep sub-pixels and the shared sub-pixels are obtained by partitioning the light-emitting pixels, and are taken as an example to introduce the light-emitting circuit 10121. Referring to FIG. 21, the light-emitting circuit 10121 corresponding to the light-emitting pixel 10131 of the anti-peep display region 101a can include a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, a seventh transistor T7, an eighth transistor T8, and a storage capacitor Cst.

[0223] The gate of the first transistor T1 is coupled with a first reset signal terminal (Rst1), the first electrode of the first transistor T1 is coupled with the first node N1, and the second electrode of the first transistor T1 is coupled with a first reset power terminal (Vinit1).

[0224] The gate of the second transistor T2 is coupled with a gate signal terminal (Gate), the first electrode of the second transistor T2 is coupled with the first node N1, and the second electrode of the second transistor T2 is coupled with the third node N3.

[0225] The gate of the third transistor T3 is coupled with the first node N1, the first electrode of the third transistor T3 is coupled with the second node N2, and the second electrode of the third transistor T3 is coupled with the third node N3.

[0226] The gate of the fourth transistor T4 is coupled with a gate signal terminal (Gate), the first electrode of the fourth transistor T4 is coupled with a data signal terminal (Data), and the second electrode of the fourth transistor T4 is coupled with the second node N2.

[0227] The gate of the fifth transistor T5 is coupled with a first emission control signal terminal (EM1), the first electrode of the fifth transistor T5 is coupled with a driving power terminal (VDD), and the second electrode of the fifth transistor T5 is coupled with the second node N2.

[0228] The gate of the sixth transistor T6 is coupled with a first emission control signal terminal (EM1), the first electrode of the sixth transistor T6 is coupled with the third node N3, and the second electrode of the sixth transistor T6 is coupled with the fourth node N4.

[0229] The gate of the seventh transistor T7 is coupled with a second reset signal terminal (Rst2), the first electrode of the seventh transistor T7 is coupled with a second reset power terminal (Vinit2), and the second electrode of the seventh transistor T7 is coupled with the fifth node N5.

[0230] The gate of the eighth transistor T8 is coupled with a second emission control signal terminal (EM2), the first electrode of the eighth transistor T8 is coupled with the fourth node N4, and the second electrode of the eighth transistor T8 is coupled with the fifth node N5.

[0231] The first plate of a storage capacitor Cst is coupled with the first node N1, and the second plate of the storage capacitor Cst is coupled with a driving power terminal (VDD).

[0232] One end (anode pattern m11) of the anti-peep sub-pixel 101311 included in the light-emitting pixel 10131 is connected with the fourth node N4, and the other end (cathode layer m4) is connected with a pull-down power terminal (VSS). One end (anode pattern m11) of the shared sub-pixel 101312 included in the light-emitting pixel 10131 is connected with the fifth node N5, and the other end (cathode layer m4) is connected with the pull-down power terminal (VSS).

[0233] As shown in FIG. 21, when the fifth transistor T5, the third transistor T3 and the sixth transistor T6 in the light emitting circuit 10121 are all in the on state, the driving signal of the driving power supply end VDD can be transmitted to one end of the privacy sub-pixel 101311 in the light emitting pixel 10131, and in this case, the privacy sub-pixel 101311 can be used to emit light. When the fifth transistor T5, the third transistor T3, the sixth transistor T6 and the eighth transistor T8 in the light emitting circuit 10121 are all in the on state, the driving signal of the driving power supply end VDD can be transmitted to one end of the privacy sub-pixel 101311 and the shared sub-pixel 101312 in the light emitting pixel 10131, and in this case, the privacy sub-pixel 101311 and the shared sub-pixel 101312 can be used to emit light.

[0234] That is, in the circuit design shown in FIG. 21, as long as the shared sub-pixel 101312 emits light, the privacy sub-pixel 101311 must emit light. Therefore, in the privacy display mode or the sharing display mode, the privacy sub-pixel 101311 can be used to emit light. Only in the sharing display mode, the shared sub-pixel 101312 can emit light by controlling the eighth transistor T8 to be in the on state.

[0235] In the embodiment of the present application, as shown in FIG. 22, in order to realize independent control of the privacy sub-pixel 101311, a ninth transistor T9 can be arranged between the fourth node N4 and the privacy sub-pixel 101311. The gate of the ninth transistor T9 is coupled with the third light emitting control signal end (EM3), the first electrode of the ninth transistor T9 is coupled with the fourth node N4, and the second electrode of the ninth transistor T9 is connected with one end (anode pattern m11) of the privacy sub-pixel 101311.

[0236] As shown in FIG. 22, when the fifth transistor T5, the third transistor T3, the sixth transistor T6 and the ninth transistor T9 in the light emitting circuit 10121 are all in the on state, the driving signal of the driving power supply end VDD can be transmitted to one end of the privacy sub-pixel 101311 in the light emitting pixel 10131, and in this case, the privacy sub-pixel 101311 can be used to emit light. When the fifth transistor T5, the third transistor T3, the sixth transistor T6 and the eighth transistor T8 in the light emitting circuit 10121 are all in the on state, the driving signal of the driving power supply end VDD can be transmitted to one end of the privacy sub-pixel 101311 and the shared sub-pixel 101312 in the light emitting pixel 10131, and in this case, the shared sub-pixel 101312 can be used to emit light.

[0237] That is, in the circuit design shown in FIG. 22, in the privacy display mode, the ninth transistor T9 is turned on and the eighth transistor T8 is turned off, so that the privacy sub-pixel 101311 emits light and the shared sub-pixel 101312 does not emit light. In the shared display mode, the eighth transistor T8 is turned on and the ninth transistor T9 is turned off, so that the shared sub-pixel 101312 emits light and the privacy sub-pixel 101311 does not emit light.

[0238] For the two circuit designs shown in FIG. 21 and FIG. 22, the light-emitting circuit 10121 shown in FIG. 21 cannot control the privacy sub-pixel 101311 individually, and the flexibility is poor, but the number of transistors is small, and the layout design is relatively simple. The light-emitting circuit 10121 shown in FIG. 22 can control the privacy sub-pixel 101311 individually, and the flexibility is good, but the number of transistors is large, and the layout design is relatively difficult. That is, the two circuit designs have advantages and disadvantages, so in actual application, the light-emitting circuit 10121 can be designed according to the needs of the product to maximize the needs of the product.

[0239] In the embodiment of the present application, when the light-emitting pixel is divided into the privacy pixel and the shared pixel, the light-emitting circuit 10121 corresponding to the light-emitting pixel 10131 can be the circuit structure (i.e., 7T1C circuit) obtained by removing the eighth transistor T8 and the shared sub-pixel 101312 in FIG. 21 and replacing the privacy sub-pixel 101311 in FIG. 21 with the light-emitting pixel 10131. In this case, each light-emitting circuit 10121 can control the corresponding light-emitting pixel 10131.

[0240] Optionally, in the privacy display mode, the light-emitting circuit of the shared pixel area 101a2 can control the shared pixel not to emit light, and the light-emitting circuit of the privacy pixel area 101a1 can control the privacy pixel to emit light. In the shared display mode, the light-emitting circuit of the shared pixel area 101a2 can control the shared pixel to emit light, and the light-emitting circuit of the privacy pixel area 101a1 can control the privacy pixel to emit light or not to emit light.

[0241] In the embodiment of the present application, since the driving circuit layer 1012 and the light-emitting device layer 1013 include multiple metal layers (such as gate layer, source-drain layer, anode layer, cathode layer, etc.), the reflectivity of the display module 100 to the ambient light is relatively high, and the reflected light will affect the display effect of the display module 100. The present application solves the problem caused by the reflection of ambient light in the following three ways.

[0242] Scheme one, a circular polarizer (POL) is arranged on the light-out surface of the display module 100 to reduce reflection. The ambient light incident from the light-out surface of the display module 100 is converted into left-handed (right-handed) circularly polarized light after passing through the circular polarizer, and the left-handed (right-handed) circularly polarized light is reflected by the metal layer in the display module 100, and the direction of the reflected circularly polarized light changes to right-handed (left-handed), and the right-handed (left-handed) circularly polarized light cannot be transmitted through the circular polarizer. Thus, the reflection phenomenon of the display module to ambient light can be reduced.

[0243] However, due to the large thickness of the circular polarizer itself, when arranged in the OLED display device, it inevitably makes the entire OLED display device thicker.

[0244] Scheme two, referring to FIG. 16, the display module 100 includes a color film assembly (COE) 109 arranged on the side of the light-emitting device layer 1013 away from the substrate 1011. The color film assembly 109 includes a first light shielding layer 1091 and a light filtering part 1092. The light filtering part 1092 can be used to filter the light emitted by the light-emitting pixels. The ambient light incident from the light-out surface of the display module 100 enters the inside of the display module 100 from the light filtering part 1092, and the light filtering part 1092 that can only transmit light of a single color can filter out most of the light. A small part of the light entering the inside of the display module 100 is lost again by the metal layer and the microcavity effect in the display module 100. Therefore, when the light is emitted again after passing through the light filtering part 1092, the reflected light can be filtered again by the light filtering part 1092, further reducing the intensity of the emitted reflected light. Thus, the intensity of the reflected light emitted can be very small. In this case, a circular polarizer does not need to be arranged to reduce reflection.

[0245] Due to the large thickness of the circular polarizer itself, it may cause the overall thickness of the display module to be thicker. Therefore, the scheme of arranging the color film assembly 109 achieves the effect of reducing the thickness of the display module compared with the scheme of arranging the circular polarizer.

[0246] Scheme three, as described in the above embodiments, the protective layer 104 is arranged as a reflection adjustment layer, and the material of the reflection adjustment layer can be gray OC.

[0247] Since the preparation process of the color film assembly 109 is relatively complex, the scheme of arranging the protective layer 104 as a reflection adjustment layer can not only reduce reflection but also simplify the process and reduce the number of mask plates used in the preparation process compared with the scheme of arranging the color film assembly 109.

[0248] For the above-mentioned solution two, in the embodiments of the present application, the display module 100 further includes a color film assembly 109 located on the side of the light-emitting device layer 1013 of the display panel 101 away from the substrate 1011. The color film assembly 109 includes a first light-blocking layer (BM1) 1091 and a plurality of light filtering parts 1092.

[0249] The first light-blocking layer 1091 has a plurality of light-emitting openings 1091a, and the orthographic projection of each light-emitting opening 1091a on the substrate 1011 and the orthographic projection of the corresponding light-emitting region on the substrate 1011 overlap. The orthographic projection of each light filtering part 1092 on the substrate 1011 is at least located within the orthographic projection of one light-emitting opening 1091a on the substrate 1011. The light emitted by the light-emitting region can be emitted after passing through the corresponding light filtering part 1092. In the display module 100 shown in FIG. 16, each light filtering part 1092 is located within the corresponding light-emitting opening 1091a.

[0250] In the embodiments of the present application, in the case where the display module 100 includes the color film assembly 109, the first light line light adjusting structure 102 can include the first light-blocking layer 1091 located between the peep-proof pixel area 101a1 and the shared pixel area 101a2, and between the orthographic projections of adjacent peep-proof light-emitting regions on the substrate. The second light line light adjusting structure 103 can include the first light-blocking layer 1091 located between the orthographic projections of adjacent shared light-emitting regions on the substrate.

[0251] The solution of the embodiments of the present application multiplexes the first light-blocking layer 1091 in the color film assembly 109 as the first light line light adjusting structure 102 and the second light line light adjusting structure 103, and the thickness of at least part of the first light line light adjusting structure 102 close to the peep-proof light-emitting region is greater than the thickness of the conventional first light-blocking layer 1091. That is, in the case where the display module of the embodiments of the present application includes the color film assembly 109 (COE product), when the first light-blocking layer of the color film assembly is prepared, the height of the part of the first light-blocking layer 1091 multiplexed as the first light line light adjusting structure 102 can be directly made high. The part of the first light-blocking layer 1091 with higher height can serve as the light-blocking layer required for peep-proof. Thus, the peep-proof effect can be achieved without the need for other light-blocking layers, and the process is simplified and cost is saved.

[0252] Optionally, the thickness of the first light line light adjusting structure 102 can range from 3 μm to 50 μm, for example, the thickness of the first light line light adjusting structure 102 is 10 μm, 20 μm, 30 μm, etc.

[0253] Referring to FIG. 23 and FIG. 24, the distance between the first light shielding layer 1091 and the surface of the substrate 1011, which is located between the peep-proof pixel area 101a1 and the shared pixel area 101a2 and between the orthographic projections of the adjacent peep-proof light emitting areas on the substrate, is greater than the distance between the first light shielding layer 1091 and the surface of the substrate 1011, which is located between the orthographic projections of the adjacent shared light emitting areas on the substrate.

[0254] In the display module 100 shown in FIG. 23, the thickness of the first light shielding layer 1091, which is located between the peep-proof pixel area 101a1 and the shared pixel area 101a2 and between the orthographic projections of the adjacent peep-proof light emitting areas on the substrate, is greater than the thickness of the first light shielding layer 1091, which is located between the orthographic projections of the adjacent shared light emitting areas on the substrate, so that the thickness of the first light adjusting structure 102 is greater than the thickness of the second light adjusting structure 103.

[0255] In the display module 100 shown in FIG. 24, in the peep-proof display area 101a, the two filter parts 1092 corresponding to each peep-proof light emitting area F1 and the adjacent light emitting area of the peep-proof light emitting area F1 are sequentially stacked on the side of the first light shielding layer 1091 close to the substrate 1011. Since the stacked filter part 1092 can shield light and has a certain thickness, the stacked filter part 1092 can not only shield light, but also raise the first light shielding layer 1091. In this case, the stacked filter part 1092 and the first light shielding layer 1091 on the side of the stacked filter part 1092 away from the substrate 1011 can jointly form the first light adjusting structure 102.

[0256] Optionally, the thickness of each filter part 1092 in the two stacked filter parts 1092 ranges from 1 μm to 4 μm, and the thickness of the first light shielding layer 1091 can be a conventional thickness ranging from 1 μm to 1.5 μm. That is, the thickness of the first light adjusting structure 102 can range from 3 μm to 9.5 μm.

[0257] In the display module 100 shown in FIG. 25, the thickness of the first light shielding layer 1091 between the peep-proof pixel area 101a1 and the shared pixel area 101a2 and between the orthographic projections of the adjacent peep-proof light-emitting areas F1 on the substrate 1011 is greater than the thickness of the first light shielding layer 1091 between the orthographic projections of the adjacent shared light-emitting areas F2 on the substrate 1011, so that the thickness of the first light ray light-adjusting structure 102 is greater than the thickness of the second light ray light-adjusting structure 103. In addition, the first light shielding layer 1091 between the peep-proof pixel area 101a1 and the shared pixel area 101a2 can be reused as the first light ray light-adjusting structure 102 with a high difference design and including the first part 1023 and the second part 1024.

[0258] In the embodiment of the present application, referring to FIG. 26, the display module 100 further includes a plurality of light blocking parts 110 arranged at intervals. The plurality of light blocking parts 110 are located on the side of the light shielding part 1092 of the peep-proof light-emitting area F1 away from the substrate 1011. In this way, the peep-proof effect of the peep-proof light-emitting area F1 can be further enhanced.

[0259] Optionally, the distance between two adjacent light blocking parts 110 ranges from 1 μm to 20 μm. The width of each light blocking part 110 can be less than 1 μm.

[0260] In the embodiment of the present application, referring to FIG. 27, the display module 100 further includes a first insulating layer 111 between the light-emitting device layer 1013 and the color filter assembly 109. The first insulating layer 111 has a plurality of first light-adjusting openings K1. The orthographic projections of the plurality of first light-adjusting openings K1 on the substrate 1011 are located within the orthographic projections of the first light shielding layer 1091 on the substrate 1011. Part of the first light ray light-adjusting structure 102 is located within the first light-adjusting opening K1.

[0261] For example, the height of the part of the first light ray light-adjusting structure 102 located within the first light-adjusting opening K1 can be equal to the depth of the first light-adjusting opening K1. In this way, by arranging the first light-adjusting opening K1 on the first insulating layer 111 and locating part of the first light ray light-adjusting structure 102 within the first light-adjusting opening K1, the thickness of the first light ray light-adjusting structure 102 can be equal to the sum of the height of the part located within the first light-adjusting opening K1 and the height of the part located outside the first light-adjusting opening K1. Optionally, the height of the part of the first light ray light-adjusting structure 102 located outside the first light-adjusting opening K1 can be the height of the conventional first light shielding layer 1091, i.e., the height ranges from 1 μm to 1.5 μm.

[0262] As a possible case, the part of the first light adjusting structure 102 located in the first light adjusting opening K1 can be a part of the first light shielding layer 1091. In this case, the first light shielding layer 1091 can include the part located in the first light adjusting opening K1 and the part located outside the first light adjusting opening K1 to form the light emitting opening 1091a. In addition, the height of the part of the first light shielding layer 1091 located outside the first light adjusting opening K1 can be the regular height of the first light shielding layer 1091. Thus, the height of the first light adjusting structure 102 can be equal to the sum of the height of the part of the first light shielding layer 1091 located in the first light adjusting opening K1 and the height of the part located outside the first light adjusting opening K1, i.e., greater than the regular height of the first light shielding layer 1091, which can ensure that the display module avoids light leakage from the privacy light emitting area F1 to other light emitting areas adjacent to it in the privacy display mode, and improves the privacy effect in the privacy display mode.

[0263] Optionally, the first light adjusting structure 102 has a height in the range of 3 μm to 50 μm, which is good for light shielding of the privacy light emitting area F1. Therefore, the height of the first insulating layer 111 can also be in the range of 3 μm to 50 μm, or the height of the first insulating layer 111 can be greater than the thickness of the first light adjusting structure 102.

[0264] In the embodiments of the present application, referring to FIG. 16, if the display module 100 includes the encapsulation buffer layer 107 and the touch film layer 108, the display module 100 can further include a touch protection flat layer 112 located between the color film assembly 109 and the touch film layer 108. The material of the touch protection flat layer 112 can be optical cement (OC), i.e., the touch protection flat layer 112 can be a TOC (touch OC) layer. Then, the first insulating layer 111 described in the above embodiments can refer to at least one of the touch protection flat layer 112, the touch insulating layer 1082 in the touch film layer 108, and the encapsulation buffer layer 107. That is, the first light adjusting opening K1 can refer to an opening provided in at least one of the touch protection flat layer 112, the touch insulating layer 1082, and the encapsulation buffer layer 107.

[0265] Referring to FIG. 28, in order to avoid the influence of the first light adjusting opening K1 on the first touch electrode s1 and the second touch electrode s2, the orthographic projection of the first light adjusting opening K1 on the substrate substrate 1011 can be made not to overlap with the orthographic projection of the electrode patterns of the first touch electrode s1 and the second touch electrode s2 on the substrate substrate 1011.

[0266] As another possible case, referring to FIG. 29, the material of the portion of the first light control structure 102 located within the portion of the first light control opening K1 can include a reflective metal, which can be referred to as a first reflective portion E1. In this case, the first light control structure 102 includes the first light shielding layer 1091 and the first reflective portion E1. The first light shielding layer 1091 can include a portion located outside the first light control opening K1 to form a light emitting opening 1091a, and the height of the first light shielding layer 1091 can be the regular height of the first light shielding layer 1091. The first reflective portion E1 can fill in the first light control opening K1, and the height of the first reflective portion E1 can be equal to the depth of the first light control opening K1. Thus, the height of the first light control structure 102 can be equal to the sum of the height of the first light shielding layer 1091 and the height of the first reflective portion E1, i.e., greater than the regular height of the first light shielding layer 1091, which can ensure that the display module 100 avoids light leakage from the privacy light emitting area F1 to other light emitting areas adjacent to the privacy light emitting area F1 in the privacy display mode, and improves the privacy effect in the privacy display mode.

[0267] Optionally, the width of the first reflective portion E1 can be greater than 2 μm, and the orthographic projection of the first reflective portion E1 on the substrate 1011 is located within the orthographic projection of the first light shielding layer 1091 on the substrate 1011, and the orthographic projection of the first reflective portion E1 on the substrate 1011 is designed to be inwardly recessed relative to the orthographic projection of the first light shielding layer 1091 on the substrate 1011. For example, the distance between the orthographic projection of the boundary of the first reflective portion E1 on the substrate 1011 and the orthographic projection of the boundary of the first light shielding layer 1091 on the substrate 1011 is greater than 0.1 μm.

[0268] In addition, the thickness of the first reflective portion E1 is related to the depth of the first light control opening K1, and the first light control opening K1 is arranged in the first insulating layer 111, so the depth of the first light control opening K1 is related to the height of the first insulating layer 111. For example, when the first light control opening K1 is a through opening, the depth of the first light control opening K1 is equal to the total height of the first insulating layer 111. When the first light control opening K1 is a blind opening, the depth of the first light control opening K1 is less than the total height of the first insulating layer 111.

[0269] Optionally, referring to FIG. 29, if the display module 100 includes the encapsulation buffer layer 107 and does not include the touch film layer 108, the height of the first reflective portion E1 can be maximally equal to the height of the encapsulation buffer layer 107. For example, the height of the encapsulation buffer layer 107 ranges from 0.13 μm to 3 μm. If the display module 100 includes the encapsulation buffer layer 107, the touch film layer 108, and the touch protection flat layer 112, the height of the first reflective portion E1 can be maximally equal to the sum of the heights of the encapsulation buffer layer 107, the touch insulating layer 1082, and the touch protection flat layer 112.

[0270] In the embodiment of the present application, the preparation process of the first reflecting part E1 includes: forming a first insulating film; forming a first light-adjusting opening K1 in the first insulating film to obtain a first insulating layer 111; depositing a reflecting metal film; and performing a patterning process on the reflecting metal film to obtain the first reflecting part E1 arranged in the first light-adjusting opening K1. The patterning process includes: photoresist coating, exposure, development, etching, and photoresist removal.

[0271] In the embodiment of the present application, referring to FIG. 30, the display module 100 further includes a second insulating layer 113 located on the side of the color film component 109 away from the substrate base plate 1011. The second insulating layer 113 has a plurality of second light-adjusting openings K2. The orthogonal projection of the plurality of second light-adjusting openings K2 on the substrate base plate 1011 is located within the orthogonal projection of the first light-blocking layer 1091 on the substrate base plate 1011. A part of the second light ray adjusting structure 103 is located in the second light-adjusting opening K2. For example, the height of the part of the first light ray adjusting structure 102 located in the second light-adjusting opening K2 can be equal to the depth of the second light-adjusting opening K2.

[0272] As a possible case, the material of the part of the first light ray adjusting structure 102 located in the second light-adjusting opening K2 includes a light-blocking material, which can be referred to as a light-blocking part. For example, the light-blocking material of the light-blocking part can be the same as the material of the first light-blocking layer 1091. In this case, after the preparation of the color film component 109 is completed, a second insulating film is first formed, then a second light-adjusting opening K2 is formed in the second insulating film to obtain a second insulating layer 113, and finally a light-blocking material is filled in the second light-adjusting opening K2 to obtain the light-blocking part.

[0273] As another possible case, referring to FIG. 30, the part of the first light ray adjusting structure 102 located in the second light-adjusting opening K2 can include a reflecting metal, which can be referred to as a second reflecting part E2. In this case, after the preparation of the color film component 109 is completed, a second insulating film is first formed, then a second light-adjusting opening K2 is formed in the second insulating film to obtain a second insulating layer 113, and finally a reflecting metal is filled in the second light-adjusting opening K2 to obtain the second reflecting part E2.

[0274] Optionally, referring to FIG. 30, in the case where the material of the part of the first light ray adjusting structure 102 located in the second light-adjusting opening K2 includes a reflecting metal, the first light ray adjusting structure 102 further includes: a second light-blocking layer 114 located on the side of the second reflecting part E2 away from the substrate base plate 1011. The orthogonal projection of the second light-blocking layer 114 on the substrate base plate 1011 covers the orthogonal projection of the second reflecting part E2 on the substrate base plate 1011, and the orthogonal projection of the second light-blocking layer 114 on the substrate base plate 1011 does not overlap with the orthogonal projection of the light-emitting area on the substrate base plate 1011.

[0275] By disposing the second light shielding layer (BM2) 114 on the side of the second reflection portion E2 away from the substrate 1011, the second light shielding layer 114 can absorb the light of the light emitting region reflected by the second reflection portion E2, so as to avoid the influence of the light reflected by the second reflection portion E2 on the display effect due to the too high reflectivity of the second reflection portion E2.

[0276] Optionally, the width of the second reflection portion E2 can be the same as the width of the first reflection portion E1, for example, the width of the second reflection portion E2 and the width of the first reflection portion E1 can be greater than 2 μm. Moreover, the orthographic projection of the second reflection portion E2 on the substrate 1011 is designed to be inside the orthographic projection of the first light shielding layer 1091 on the substrate 1011. For example, the distance between the orthographic projection of the boundary of the second reflection portion E2 on the substrate 1011 and the orthographic projection of the boundary of the first light shielding layer 1091 on the substrate 1011 is greater than 0.1 μm.

[0277] In addition, the height of the second reflection portion E2 is related to the depth of the second light adjusting opening K2, and the second light adjusting opening K2 is disposed in the second insulating layer 113, so the depth of the second light adjusting opening K2 is related to the thickness of the second insulating layer 113. For example, when the second light adjusting opening K2 is a through opening, the depth of the second light adjusting opening K2 is equal to the total height of the second insulating layer 113. When the second light adjusting opening K2 is a blind opening, the depth of the second light adjusting opening K2 is less than the total height of the second insulating layer 113.

[0278] In the embodiment of the present application, referring to FIG. 31, the first light adjusting structure 102 can simultaneously include the first reflection portion E1 and the second reflection portion E2. That is, the reflection portion is disposed on the side of the color film component 109 close to the substrate 1011 and the side of the color film component 109 away from the substrate 1011 for reflecting the light, and the reflected light is absorbed by the first light shielding layer 1091 in the color film component 109 and the additionally disposed second light shielding layer 114. In this case, the height of the first light adjusting structure 102 can be the sum of the heights of the first reflection portion E1, the second reflection portion E2, the first light shielding layer 1091 and the second light shielding layer 114.

[0279] Alternatively, referring to FIG. 32, the first light adjusting structure 102 can simultaneously include the first reflection portion E1 and the second reflection portion E2, and the first reflection portion E1 and the second reflection portion E2 can constitute an integrated reflection portion penetrating the first light shielding layer 1091 of the color film component 109.

[0280] Further, referring to FIG. 33, in a case where the material of the portion of the first light control structure 102 located in the first light control opening K1 includes reflective metal, the material of the portion of the first light control structure 102 located in the first light control opening K1 further includes organic material, which can be referred to as a first organic portion J1. The first reflective portion E1 can be located on the sidewall of the organic material close to the first light control opening K1. In addition, in a case where the material of the portion of the first light control structure 102 located in the second light control opening K2 includes reflective metal, the material of the portion of the first light control structure 102 located in the second light control opening K2 further includes organic material, which can be referred to as a second organic portion J2. The second reflective portion E2 can be located on the sidewall of the organic material close to the second light control opening K2.

[0281] For example, the first organic portion J1 in a strip shape is first formed in the first light control opening K1, and then reflective metal is coated outside the first organic portion J1 to obtain the first reflective portion E1. The second organic portion J2 in a strip shape is first formed in the second light control opening K2, and then reflective metal is coated outside the second organic portion J2 to obtain the second reflective portion E2.

[0282] Optionally, the organic material of the first organic portion J1 and the second organic portion J2 can be acrylic resin. For example, it can include one or more combinations of polymethyl methacrylate (PMMA), polyacrylic acid, ethylhexyl acrylate, pentafluoropropyl acrylate, polyethylene glycol dimethacrylate, and ethylene glycol dimethacrylate.

[0283] In the embodiments of the present application, the first light control structure 102 in the above-mentioned scheme is arranged on the side of the light-emitting device layer 1013 of the display panel 101 away from the substrate 1011. The following scheme introduces the first light control structure 102 arranged in the interior of the display panel 101. The first light control structure 102 arranged in the interior of the display panel 101 can mean that the film layer included in the display panel 101 can be improved and reused as the first light control structure 102. The film layer included in the display panel 101 can include the film layer in the driving circuit layer and the light-emitting device layer described in the above-mentioned embodiments.

[0284] Referring to FIG. 34, the first light control structure 102 includes a pixel boundary layer m2 located between the peep-proof pixel area 101a1 and the shared pixel area 101a2, and between the orthographic projections of adjacent peep-proof light-emitting areas F1 on the substrate 1011. The second light control structure 103 includes a pixel boundary layer m2 located between the orthographic projections of adjacent shared light-emitting areas F2 on the substrate 1011.

[0285] Optionally, the thickness of the pixel defining layer m2 between the peep-proof pixel region 101a1 and the shared pixel region 101a2, and between the orthographic projections of the adjacent peep-proof light-emitting regions F1 on the substrate 1011, ranges from 3 μm to 50 μm, and the thickness of the pixel defining layer m2 between the orthographic projections of the adjacent shared light-emitting regions F2 on the substrate 1011 ranges from 0.5 μm to 3 μm.

[0286] Referring to FIG. 34, the pixel defining layer m2 between the peep-proof pixel region 101a1 and the shared pixel region 101a2, and between the orthographic projections of the adjacent peep-proof light-emitting regions F1 on the substrate 1011, includes a first pixel defining portion m21 and a second pixel defining portion m22. In this way, the thickness of the first light ray adjusting structure 102 can be the sum of the thicknesses of the first pixel defining portion m21 and the second pixel defining portion m22. The first pixel defining portion m21 and the second pixel defining portion m22 can be light-blocking walls or light-blocking structures in the vertical direction.

[0287] The first pixel defining portion m21 is located on the side of the cathode layer m4 close to the substrate 1011, and the first pixel defining portion m21 and the pixel defining layer m2 between the orthographic projections of the adjacent shared light-emitting regions on the substrate are prepared by the same patterning process. The second pixel defining portion m22 is located on the side of the cathode layer m4 away from the substrate 1011.

[0288] Optionally, the angle between the sidewall of the second pixel defining portion m22 and the bottom surface of the second pixel defining portion m22 can be an acute angle or a right angle. That is, the cross-sectional shape of the second pixel defining portion m22 can be rectangular or trapezoidal. The present application does not limit this.

[0289] Optionally, the material of the second pixel defining portion m22 can be a black light-blocking material or a metal oxide. When the material of the second pixel defining portion m22 is a black light-blocking material, the second pixel defining portion m22 can be referred to as a black pixel defining layer (BPDL).

[0290] Since the cathode layer m4 is disposed between the first pixel defining portion m21 and the second pixel defining portion m22, the cathode layer m4 is formed after the first pixel defining portion m21 is prepared and before the second pixel defining portion m22 is prepared. In this way, when the cathode layer m4 is formed, the cathode layer m4 only needs to climb along the first pixel defining portion m21, which can avoid the cathode layer m4 from being broken during the climbing process and ensure the continuity of the cathode layer m4. The climbing height of the cathode layer m4 depends on the thickness of the first pixel defining portion m21.

[0291] Of course, the cathode layer m4 can also be disposed on the side of the second pixel defining portion m22 away from the substrate 1011. The present application does not limit the stacking relationship between the cathode layer m4 and the second pixel defining portion m22.

[0292] It should be noted that in the case of disposing the cathode layer m4 on the side of the second pixel defining portion m22 away from the substrate 1011, the cathode layer m4 needs to climb along the first pixel defining portion m21 and the second pixel defining portion m22, and the total thickness of the first pixel defining portion m21 and the second pixel defining portion m22 is relatively thick, which may cause the cathode layer m4 to break during the climbing process.

[0293] Therefore, in order to ensure the normal transmission of the signal of the cathode layer m4 when the cathode layer m4 is disposed on the side of the second pixel defining portion m22 away from the substrate 1011, referring to FIG. 35, the light emitting device layer 1013 further comprises a first conductive clamping layer m5 between the first pixel defining portion m21 and the second pixel defining portion m22.

[0294] The orthographic projection of the first conductive clamping layer m5 on the substrate 1011 is located within the orthographic projection of the first pixel defining portion m21 on the substrate 1011, and the orthographic projection of the second pixel defining portion m22 on the substrate 1011 is located within the orthographic projection of the first conductive clamping layer m5 on the substrate 1011. That is, the area of the orthographic projection of the first pixel defining portion m21 on the substrate 1011, the area of the orthographic projection of the first conductive clamping layer m5 on the substrate 1011, and the area of the orthographic projection of the second pixel defining portion m22 on the substrate 1011 can decrease in turn. In this way, on the one hand, the existence of the first conductive clamping layer m5 can avoid affecting the normal light emission of the light emitting area, and on the other hand, the first conductive clamping layer m5 can have a clamping area beyond the second pixel defining portion m22.

[0295] Since the light emitting device layer 1013 comprises a plurality of light emitting pixels 10131, the light emitting patterns of different light emitting pixels 10131 need to be arranged in intervals (i.e., disconnected), and there is no signal transmission, therefore, referring to FIG. 35, the orthographic projection on the substrate 1011 of the side of the light emitting pattern m31 in the light emitting pixel 10131 close to another light emitting pixel 10131 and the orthographic projection on the substrate 1011 of the first conductive clamping layer m5 do not overlap (region W1), thereby avoiding the light emitting patterns of different light emitting pixels 10131 being electrically connected through the first conductive clamping layer m5.

[0296] Furthermore, since the cathode layer m4 of the different light emitting pixels 10131 is a continuous whole layer film layer, referring to FIG. 35, the orthographic projection of the cathode layer m4 on the substrate 1011 and the orthographic projection of the first conductive connecting layer m5 on the substrate 1011 partially overlap. In this way, the part of the cathode layer m4 located in the area of the different light emitting pixels 10131 is connected through the first conductive connecting layer m5, avoiding the problem of short circuit or too high resistance of the cathode layer m4 due to the high step difference of the cathode layer m4.

[0297] In the embodiments of the present application, the organic functional layer n6 of the different light emitting pixels 10131 can also be a continuous whole layer film layer. Referring to FIG. 35, the orthographic projection of the organic functional layer m6 on the substrate 1011 and the orthographic projection of the first conductive connecting layer m5 on the substrate 1011 partially overlap. That is, the part of the organic functional layer m6 located in the area of the different light emitting pixels 10131 is connected through the first conductive connecting layer m5, and then the part of the cathode layer m4 located in the area of the different light emitting pixels 10131 is indirectly connected through the organic functional layer m6 and the first conductive connecting layer m5.

[0298] For the light emitting pixels 10131 in the privacy display area 101a, the light emitting pattern m31 of the privacy sub-pixel 101311 and the light emitting pattern m31 of the shared sub-pixel 101312 included in the light emitting pixel 10131 can be shared. Referring to FIG. 35, the orthographic projection of the light emitting pattern m31 on the substrate 1011 and the orthographic projection of the first conductive connecting layer m5 between the privacy sub-pixel 101311 and the shared sub-pixel 101312 on the substrate 1011 partially overlap (area W2).

[0299] Optionally, the material of the first conductive connecting layer m5 can be metal or conductive oxide, such as at least one of silver (Ag), aluminum (Al), titanium (Ti), indium tin oxide (ITO) and indium zinc oxide (IZO). The thickness of the second pixel defining part m22 ranges from 2 μm to 5 μm.

[0300] In the embodiment of the present application, referring to FIG. 36, the pixel definition layer m2 is located on the side of the cathode layer m4 close to the substrate 1011. In this case, the pixel definition layer m2 can be prepared by using a half tone mask (HTM). In order to avoid the cathode layer m4 from being broken due to the thickness of the pixel definition layer m2 between the peep-proof pixel area 101a1 and the shared pixel area 101a2 and between the orthographic projections of adjacent peep-proof light-emitting areas on the substrate, referring to FIG. 36, the side edges of the pixel definition layer m2 between the peep-proof pixel area 101a1 and the shared pixel area 101a2 and between the orthographic projections of adjacent peep-proof light-emitting areas on the substrate are in a stepped structure. In this way, the total height required for the cathode layer m4 to climb is divided into a plurality of smaller climbing heights, thereby reducing the possibility of the cathode layer m4 from being broken due to climbing.

[0301] Alternatively, referring to FIG. 36, the stepped structure can be a straight-line type of step. Alternatively, the stepped structure can also be a step connected by an arc. The embodiment of the present application does not limit this.

[0302] Alternatively, the number of steps included in the stepped structure can range from 2 to 5. In addition, the thickness of the steps included in the stepped structure can be uniform, for example, the thickness of each step can be equal to the total thickness of the pixel definition layer m2 divided by the number of steps.

[0303] In the embodiment of the present application, the pixel definition layer m2 is located on the side of the cathode layer m4 close to the substrate 1011. In this case, the pixel definition layer m2 can be prepared by using a half tone mask (HTM). In order to ensure that the cathode layer m4 can normally transmit signals, referring to FIG. 37, the display module 100 further includes a second conductive bonding layer 115 and a light-absorbing layer 116 on the side wall of the pixel definition layer m2 between the peep-proof pixel area 101a1 and the shared pixel area 101a2 and between the orthographic projections of adjacent peep-proof light-emitting areas on the substrate.

[0304] One end of the second conductive bonding layer 115 is electrically connected to the part of the cathode layer m4 located in the area of the hollowed-out region, and the other end is electrically connected to the part of the cathode layer m4 located away from the substrate 1011. The light-absorbing layer 116 is located on the side of the side wall of the pixel definition layer m2 away from the second conductive bonding layer 115, and the light-absorbing layer 116 is used to absorb light.

[0305] Alternatively, the material of the second conductive bonding layer 115 can be metal, for example, the material of the first conductive bonding layer m5 can be one of silver (Ag), aluminum (Al) and titanium (Ti). The material of the light-absorbing layer 116 can be light-absorbing metal oxide, which is used to reduce reflection.

[0306] In the embodiments of the present application, the first light adjusting structure 102 can be arranged in the display panel 101, and also arranged on the side of the light emitting device layer 1013 of the display panel 101 away from the substrate 1011. Referring to FIG. 38, the pixel defining layer m2 and the first light shielding layer 1091 in the color film component 109 can be used as the first light adjusting structure 102. In this case, the size of the light emitting opening 1091a corresponding to the peep-proof sub-pixel 101311 in the first light shielding layer 1091 can be smaller than the size of the light emitting opening 1091a corresponding to the shared sub-pixel 101312 in the first light shielding layer 1091.

[0307] Alternatively, referring to FIG. 39 and FIG. 40, in the case where the display module 100 does not include the color film component 109, the first light adjusting structure 102 can include the pixel defining layer m2 and the light adjusting material G arranged in the first light adjusting opening K1 of the first insulating layer 111. The light adjusting material G can be a light shielding material or a light absorbing metal oxide. FIG. 39 is used to represent the case where the light adjusting material is a light shielding material, and FIG. 40 is used to represent the case where the light adjusting material is a light absorbing metal oxide.

[0308] In the case where the light adjusting material is a light absorbing metal oxide, the light adjusting material can be prepared by using a patterning process. For example, a metal oxide film is first formed by coating, and then the metal oxide film is subjected to a patterning process so that the light adjusting material is arranged in the first light adjusting opening K1.

[0309] Referring to FIG. 41, the first insulating layer 111 can include a first sub-insulating layer 1111 (which can be a packaging buffer layer) and a second sub-insulating layer 11112 (which can be a touch insulating layer) stacked in the direction away from the substrate 1011. The first sub-insulating layer 1111 has a first opening K11, and the second sub-insulating layer 11112 has a second opening K12. The orthographic projection of the first opening K11 and the orthographic projection of the second opening K12 on the substrate 1011 do not overlap with the orthographic projection of the light emitting region on the substrate 1011, and the size of the second opening K12 is greater than the size of the first opening K11. In this way, the metal oxide film can be formed by climbing when coating.

[0310] Optionally, the first insulating layer 111 can further include a larger number of sub-insulating layers, and the number of sub-insulating layers is not limited in the embodiments of the present application. By arranging multiple sub-insulating layers, the light shielding height of the first light adjusting structure 102 can be increased, and the display effect of the peep-proof display mode can be effectively ensured.

[0311] Referring to FIG. 42, it can be seen that the first insulating layer 111, the light adjusting material G and the protective layer 104 can be located on the side of the packaging buffer layer 107, the touch film layer 108 and the touch protective flat layer 112 close to the substrate 1011.

[0312] Further, referring to FIGS. 42 and 43, the display module 100 includes a protective layer 104 that can planarize the surface of the first insulating layer 111 away from the substrate 1011.

[0313] In the embodiment, referring to FIG. 43, the display module 100 further includes a lens structure 117 located in the privacy light-emitting area F1, and a third insulating layer 118 covering the lens structure 117. The refractive index of the lens structure 117 is greater than that of the third insulating layer 118. Optionally, the material of the lens structure 117 can be optical cement (OC).

[0314] For example, the refractive index of the lens structure 117 can be greater than 1.65, and the refractive index of the third insulating layer 118 can be less than 1.6. The difference between the refractive index of the lens structure 117 and the refractive index of the third insulating layer 118 can range from 0.1 to 0.2.

[0315] In the embodiment, the light rays emitted from the display panel 101 can be incident into the lens structure 117, and can be refracted at the interface between the lens structure 117 and the third insulating layer 118, thereby converging the light rays and making the light rays exit in a small viewing angle direction. In addition, the surface of the third insulating layer 118 away from the display panel 101 can also be a planar surface.

[0316] Optionally, the shape of the lens structure 117 can be an arc-shaped lens, a hemispherical lens, or a trapezoidal lens, etc. The embodiment does not make a specific limitation in this regard.

[0317] It should be noted that, referring to FIGS. 44 and 45, for the scheme shown in FIG. 23, the lens structure 117 can be directly disposed on the side of the light filter 1092 away from the substrate 1011, and is limited above the privacy light-emitting area F1 surrounded by the first light ray adjusting structure 102. In this case, the thickness of the first light ray adjusting structure 102 can be used to dispose the lens structure 117, so as to avoid the total thickness of the display module being too thick due to the disposition of the lens structure 117. In addition, the third insulating layer 118 in this case can be the protective layer 104.

[0318] In the embodiment, referring to FIG. 16, the color film assembly 109 is located on the side of the touch film layer 108 away from the substrate 1011. Alternatively, the color film assembly 109 can also be located on the side of the touch film layer 108 close to the substrate 1011, for example, the color film assembly 109 can be located between the encapsulation film layer 106 and the touch film layer 108. Alternatively, the display module 100 can also not include the touch film layer 108.

[0319] Further, the color film assembly 109 can also have a COC (color filter on color filter) on the side away from the substrate 1011. The display module 100 can also include a cover plate, which can be located on the side of the film layer farthest away from the substrate 1011, and can be used to protect the film layer inside the display module 100. Optionally, the cover plate can be glass.

[0320] In the embodiments of the present application, referring to FIGS. 46 and 47, the display module 100 can include a bonding layer 119 and a circular polarizer 120 on the light-emitting surface without the color film assembly 109. The circular polarizer 120 can be fixed to the display module 100 by the bonding layer 119. The bonding layer 119 can be an optical adhesive (OC).

[0321] In the embodiments of the present application, FIG. 48 is a cross-sectional view of FIG. 8 along the DD' direction. As shown in FIG. 48, in the privacy display area 101a, the height of the first light adjusting structure 102 between the privacy sub-pixel 101311 and the shared sub-pixel 101312 included in the light-emitting pixel 10131 can be equal to the height of the first light adjusting structure 102 between adjacent privacy sub-pixels 101311. Of course, it can also be unequal. The present application does not limit this.

[0322] In addition, referring to FIGS. 18, 19 and 48, it can be seen that the anode pattern m11 of the privacy sub-pixel 101311 and the anode pattern m11 of the shared sub-pixel 101312 are discontinuously arranged. The anode patterns m11 of the two privacy micro-pixels included in the privacy sub-pixel 101311 are continuously arranged.

[0323] In the embodiments of the present application, in the privacy display area 101a, for the scheme of dividing the shared sub-pixel of the light-emitting pixel 10131 to obtain a plurality of shared micro-pixels, the shared light-emitting area F2 included in the light-emitting pixel 10131 can include a plurality of strip structures arranged (for example, referring to FIG. 10). The first light adjusting structure can also be located between adjacent strip structures arranged, and used to shield the light in the arrangement direction of the strip structure of the shared light-emitting area F2.

[0324] In the scenario of applying the display module 100 to vehicle display, the plurality of strip structures included in the shared light-emitting area F2 are arranged along the second direction Y, and the first light adjusting structure can also be located between adjacent strip structures arranged, which can avoid the light emitted by the shared light-emitting area F2 in the second direction Y from being irradiated to the front windshield, avoid the light reflected to the front windshield from affecting the line of sight of the driver, and avoid affecting the normal driving of the driver.

[0325] Or, for the scheme in which the shared sub-pixel of the light-emitting pixel 10131 is not further divided into multiple shared micro-pixels (such as FIGS. 3 and 8), in the scenario of applying the display module 100 to vehicle display, the shared sub-pixel of the light-emitting pixel is provided with the first light ray dimming structure 102 on both sides in the second direction Y, which can avoid the light rays emitted by the shared light-emitting area F2 of the shared sub-pixel in the second direction Y from being reflected to the front windshield, avoid the light rays reflected to the front windshield from affecting the view of the main driver, and avoid affecting the normal driving of the main driver.

[0326] Referring to FIG. 49, in the scenario of applying the display module 100 to vehicle display, the vehicle display screen can be a whole horizontal screen, which can include a main driver screen and a co-driver screen. The main driver screen is closer to the main driver position than the co-driver screen, and both the main driver screen and the co-driver screen can have an active anti-peep function. The active anti-peep function can mean that the user can autonomously select whether the main driver screen and the co-driver screen are in a shared display mode or an anti-peep display mode.

[0327] During vehicle driving, the co-driver can set the display module of the co-driver screen when watching videos and audios on the vehicle display screen, such as selecting to turn on the anti-peep display mode of the co-driver screen, so as to avoid affecting the driving of the main driver and improve the safety of driving.

[0328] Of course, in addition to being applicable to the scenario of vehicle display, the display module 100 can also be applied to mobile devices such as mobile phones and tablet computers to realize anti-peep display of mobile phones and tablet computers.

[0329] For example, in elevators, buses, high-speed rails and other public places, when using mobile phones or tablet computers to handle personal privacy matters, the anti-peep display mode can be turned on to protect privacy. Or, when handling confidential data in a company, the anti-peep display mode can be turned on to protect privacy.

[0330] In the embodiment of the present application, with reference to FIG. 50, the display panel 101 further has a shared display area 101b. The shared display area 101b includes a shared pixel area 101b1, and the shared pixel area 101b1 of the shared display area 101b includes a plurality of shared light-emitting areas. The second light ray light-adjusting structure 103 can also be located between the orthographic projections of the adjacent shared light-emitting areas F2 on the substrate 1011 in the shared display area 101b. That is, the shared display area 101b can be provided with the second light ray light-adjusting structure 103 with a small height, and the second light ray light-adjusting structure 103 can absorb light rays in a small viewing angle range, thereby avoiding light crosstalk between different shared light-emitting areas 101b1 in the shared display area 101b, and avoiding the influence of the second light ray light-adjusting structure 103 on the light emission of the shared light-emitting area F2 in the shared display area 101b, so that the shared display area F2 can realize shared display, and the display module 100 can ensure the display effect in the shared display mode.

[0331] Optionally, the first light ray light-adjusting structure 102 can also be located between the shared light-emitting area of the shared pixel area 101a2 and the peep-proof light-emitting area of the peep-proof pixel area 101a1, and the first light ray light-adjusting structure 102 can be used to avoid the light emitted by the peep-proof light-emitting area from being emitted to the shared light-emitting area of the shared pixel area 101a2.

[0332] Further, since the area where the peep-proof light-emitting area of the peep-proof display area and the shared light-emitting area of the shared display area border, if the thickness of the light-adjusting structure is set to be thick, the light emission of the shared light-emitting area will be blocked, and if the thickness of the light-adjusting structure is set to be thin, the peep-proof effect of the peep-proof light-emitting area will be poor. Therefore, in the embodiment of the present application, the light-adjusting structure of the area where the peep-proof light-emitting area of the peep-proof display area and the shared light-emitting area of the shared display area border can be designed as the first light ray light-adjusting structure with different heights. The first part 1023 of the first light ray light-adjusting structure is located close to the peep-proof light-emitting area of the peep-proof display area, and can be used to absorb the light rays of the peep-proof light-emitting area. The second part 1024 of the first light ray light-adjusting structure is located close to the shared light-emitting area of the shared display area, and can ensure the light emission of the shared light-emitting area.

[0333] It can be understood that the first light ray light-adjusting structure between the peep-proof light-emitting area of the peep-proof display area and the shared light-emitting area of the shared display area can be designed similarly to the first light ray light-adjusting structure between the peep-proof light-emitting area and the shared light-emitting area in the peep-proof display area. For example, the shared pixel area 101a2 marked in FIGS. 13, 14, 15, 23, 24, 25, 26, 44 and 45 is changed to the shared display area 101b, and the partial sectional view of the peep-proof light-emitting area F1 of the peep-proof display area 101a and the shared light-emitting area F2 of the shared display area 101b of the display module 100 can be obtained.

[0334] FIG. 51 is a partial top view of a kind of peep-proof display area and shared display area provided in an embodiment of the present application. FIG. 52 is another partial top view of a kind of peep-proof display area and shared display area provided in an embodiment of the present application. As can be seen from FIG. 51 and FIG. 52, the light-emitting area of each light-emitting pixel located in the shared display area 101b can correspond to a shared light-emitting area F2. That is, the light-emitting pixels in the shared display area 101b can not be segmented. Of course, the light-emitting pixels in the shared display area 101b can also be segmented to obtain a plurality of shared sub-pixels. The present application does not make specific limitations on the design of the light-emitting pixels in the shared display area 101b.

[0335] In the present embodiment, in the case that the display panel simultaneously includes a peep-proof display area and a shared display area, the display module 100 is applied to the scenario of vehicle display, so that the co-driver screen has an active peep-proof function.

[0336] In the present embodiment, the preparation method is briefly introduced by taking the display module shown in FIG. 41 as an example.

[0337] Step 1, referring to FIG. 53, a buffer layer n1, an active layer n2, a first gate insulating layer n3, a first gate layer n4, an interlayer dielectric layer n7, a first source-drain layer n8, a first passivation layer n9, a first planarization layer n10 and an anode layer m1 are formed on one side of the substrate 1011.

[0338] Optionally, the substrate 1011 can be a glass substrate or a flexible substrate. The material of the flexible substrate includes polyimide (PI), polyethylene naphthalate two formic acid glycol ester (PEN) and polyethylene glycol terephthalate (PET). The flexible substrate can be a single-layer structure or a multi-layer structure. If it is a multi-layer structure, a buffer layer can be added between two adjacent layers in the multi-layer structure. The buffer layer can be an inorganic material, such as at least one of silicon nitride (SiNx) and silicon oxide (SiOx).

[0339] Optionally, the patterns or via holes in the active layer n2, the first gate insulating layer n3, the first gate layer n4, the interlayer dielectric layer n7, the first source-drain layer n8, the first passivation layer n9, the first planarization layer n10 and the anode layer m1 can be prepared by a patterning process. For example, for the active layer, an active thin film can be formed first, and then the active thin film is subjected to a patterning process to obtain the active layer. The patterning process includes photoresist coating, exposure, development, etching and photoresist removal.

[0340] Step 2, referring to FIG. 54, a first pixel defining portion m21 of a pixel defining layer, a first conductive bonding layer m5 and a second pixel defining portion m22 are formed on the side of the anode layer away from the substrate.

[0341] Optionally, the orthographic projection of the first conductive bonding layer m5 on the substrate 1011 is located within the orthographic projection of the first pixel defining portion m21 on the substrate 1011, and the area of the orthographic projection of the first conductive bonding layer m5 on the substrate 1011 is smaller than the area of the orthographic projection of the first pixel defining portion m21 on the substrate 1011.

[0342] The orthographic projection of the second pixel defining portion m22 on the substrate 1011 is located within the orthographic projection of the first conductive bonding layer m5 on the substrate 1011. The area of the orthographic projection of the second pixel defining portion m22 on the substrate 1011 is smaller than the area of the orthographic projection of the first conductive bonding layer m5 on the substrate 1011.

[0343] Thus, referring to FIG. 54, the first conductive bonding layer m5 can have a bonding area Q that exceeds the second pixel defining portion m22.

[0344] Step 3, referring to FIG. 55, a packaging film layer 106 is formed.

[0345] The packaging film layer 106 includes a first film layer 1061, a second film layer 1062 and a third film layer 1063 which are stacked in sequence. The specific preparation method of the packaging film layer 106 is described above in the related description of the embodiments.

[0346] Step 4, referring to FIG. 56, a first sub-insulating layer 1111 is formed on the side of the packaging film layer 106 away from the substrate 1011. The first sub-insulating layer 1111 has a first opening K11. The first opening K11 can be prepared by a patterning process. The thickness of the first sub-insulating layer 1111 can range from 2 μm to 4 μm.

[0347] Step 5, referring to FIG. 57, a second sub-insulating layer 1112 is formed on the side of the first sub-insulating layer 1111 away from the substrate base plate 1011. The second sub-insulating layer 1112 has a second opening K12. The second opening K11 can be prepared by a patterning process. The thickness of the second sub-insulating layer 1112 can range from 2 μm to 4 μm.

[0348] Step 6, referring to FIG. 58, a light-absorbing metal oxide is formed in the second opening K12 and the first opening K1 by plating.

[0349] Step 7, referring to FIG. 41, a planar protective layer 104 is formed on the side of the light-absorbing metal oxide away from the substrate base plate 1011.

[0350] In summary, the display module provided by the embodiments of the present application includes a display panel and a first light ray light-adjusting structure. The first light ray light-adjusting structure has a high height and can be located between the privacy pixel area and the shared pixel area of the privacy display area in the display panel, and between adjacent privacy light-emitting areas, for limiting the light-emitting angle of the light emitted by the privacy light-emitting area, thereby improving the display effect of the display module in the privacy mode. In addition, no first light ray light-adjusting structure is arranged between the adjacent shared light-emitting areas in the privacy display area in the display panel, which can avoid affecting the light-emitting angle of the shared light-emitting area by the first light ray light-adjusting structure, thereby ensuring the display effect of the display module in the shared display mode.

[0351] FIG. 59 is a structural schematic diagram of a display device provided by an embodiment of the present application. Referring to FIG. 59, the display device includes a power supply assembly 200 and a display module 100 provided by the above-described embodiments.
