[0051] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods and means well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0054] The present application provides a display module according to a first aspect. Figure 1 The top view of the display module is shown in FIG. Figure 2 The cross-sectional structure diagram of the display module shown in FIG. 1 includes a substrate 100 , a plurality of first light-emitting units 200 , a first light-shielding layer 300 , and a color-resist layer 400 .

[0055] The substrate 100 includes a plurality of first pixel areas 110; a plurality of first light-emitting units 200 are located on one side of the substrate 100 and in the first pixel area 110, and the first light-emitting unit 200 includes at least one first light-emitting device 210; a first light-shielding layer 300 is located on a side of the first light-emitting device 210 away from the substrate 100, and the first light-shielding layer 300 encloses a plurality of first openings 310, and the orthographic projection of the first light-emitting device 210 on the substrate 100 overlaps with the orthographic projection of the first opening 310 on the substrate; the color-resistance layer 400 includes a plurality of color-resistance units 410, and is located on a side of the first light-shielding layer 300 away from the substrate 100, and the color-resistance unit 410 encloses a plurality of second openings 411, and at least part of the orthographic projection of the second opening 411 on the substrate 100 is located within the orthographic projection range of the first opening 310 on the substrate, and the color of the first light-emitting device 210 is different from the color of the corresponding color-resistance unit 410.

[0056] In the display module provided in the embodiment of the present application, the light emitted by the first light-emitting device 210 is blocked by the first light-shielding layer 300 and then emitted from the first opening 310. The light emitted from the first opening 310 is blocked by the color resistance unit 410 and then emitted. Since the color of the color resistance unit 410 corresponding to the first light-emitting device 210 is different from the color of the first light-emitting device 210, the color resistance unit 410 will block part of the light at a large angle, so that the anti-peeping effect of the display module is excellent.

[0057] It can be understood that the first pixel area 110 can be used for anti-peeping display.

[0058] It should be noted that the color resist unit 410 corresponding to the first light emitting device 210 means that the orthographic projection of the second opening 411 enclosed by the color resist unit 410 on the substrate 100 overlaps with the orthographic projection of the first light emitting device 210 on the substrate 100 .

[0059] For example, Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure of the display module along the AA' direction.

[0060] In one embodiment, referring to Figure 3 In the top view of the display module shown, the substrate 100 further includes a plurality of second pixel regions 120, which are used for normal display. In the first direction x, the second pixel regions 120 and the first pixel regions 110 are arranged alternately; optionally, the first pixel regions 110 and the second pixel regions 120 both extend along the second direction y, and the first direction x intersects the second direction y. For example, the first direction x and the second direction y are perpendicular to each other.

[0061] In one embodiment, referring to Figure 3 ,as well as Figure 4 The display module is a front view schematic diagram of a cross section along the BB′ direction. The display module further includes a plurality of second light emitting units 500 . The second light emitting units 500 are located in the second pixel area 120 . The second light emitting units 500 include at least one second light emitting device 510 .

[0062] Optionally, in the first direction x, in the adjacent first pixel area 110 and the second pixel area 120, the first light emitting device 210 is disposed adjacent to the second light emitting device 510; the color of the color resistance unit 410 corresponding to the first light emitting device 210 is the same as the color of the second light emitting device 510. Thus, the light emitted by the second light emitting device 510 can pass through the color resistance unit 410 corresponding to the first light emitting device 210, and during normal display, the light extraction rate of the display module is high, and the display effect is good.

[0063] In the prior art, reference Figure 5The top view structural diagram of the display module shown in the figure replaces the color resistance layer 400 in the display module of the embodiment of the present application with a black matrix 401. Although the display module in the prior art has a high anti-peeping effect, there is brightness attenuation in the first direction x during normal display, which affects the life of the display module and the maximum brightness that can be supported during normal display. In the display module of the embodiment of the present application, during normal display, the light of the second light-emitting device 510 can be emitted through the color resistance unit 410 corresponding to the first light-emitting device 210, thereby increasing the aperture ratio of the second pixel area 120, increasing the viewing angle range of the second pixel area 120, and emitting more light at a large viewing angle, which can improve the brightness decay of the viewing angle and increase the life of the product and the brightness that can be supported.

[0064] Optionally, refer to Figure 4 , the orthographic projection of the first light shielding layer 300 on the substrate 100 is located within the orthographic projection range of the color resist layer 400 on the substrate 100. Therefore, the first light shielding layer 300 will hardly affect the light emission of the second light emitting device 510 in the second pixel area 120.

[0065] In one embodiment, referring to Figure 3 , the first light-emitting unit 200 further includes at least one third light-emitting device 220 and at least one fourth light-emitting device 230; the orthographic projection of the third light-emitting device 220 on the substrate 100 overlaps with the orthographic projection of the first opening 310 on the substrate 100, and the orthographic projection of the fourth light-emitting device 230 on the substrate 100 overlaps with the orthographic projection of the first opening 310 on the substrate 100; the color of the third light-emitting device 220 is different from the color of the corresponding color-resistance unit 410, and / or the color of the fourth light-emitting device 230 is different from the color of the corresponding color-resistance unit 410. Therefore, when the first pixel area 110 is used for anti-peeping display, the anti-peeping display effect of the display module is excellent.

[0066] In one embodiment, referring to Figure 3 In the same first light emitting unit 200 , the first light emitting device 210 , the third light emitting device 220 and the fourth light emitting device 230 are arranged along the second direction y, and a plurality of first light emitting units 200 are arranged along the second direction y.

Thus, the light emitted by the fifth light emitting device 520 can pass through the color resistance unit 410 corresponding to the third light emitting device 220, and the light emitted by the sixth light emitting device 530 can pass through the color resistance unit 410 corresponding to the fourth light emitting device 230. In normal display, the light extraction rate of the display module is high, the display effect is good, and it is conducive to further reducing the brightness attenuation in the first direction x.
