[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0051] See also Figures 1 to 13 The present application proposes a display module 100 , which includes a display panel 200 and a first polarizer 300 disposed on a side of the display panel 200 away from a light emitting surface of the display module 100 .

[0052] In this embodiment, the display panel 200 includes a first substrate 211, a light shielding layer 223, a plurality of data lines Data, and a plurality of scan lines Scan disposed on the first substrate 211, and the orthographic projections of the plurality of data lines Data and the plurality of scan lines Scan on the first substrate 211 are located within the orthographic projections of the light shielding layer 223 on the first substrate 211;

[0053] In this embodiment, a dimming structure 500 is provided on the first polarizer 300, and the dimming structure 500 corresponds to the shading layer 223; at the same time, the display module 100 has a light-transmitting area TS and a non-light-transmitting area NTS, the non-light-transmitting area NTS corresponds to the shading layer 223, and the dimming structure 500 is used to guide the light incident to the non-light-transmitting area NTS to the light-transmitting area TS.

[0054] In the current display module 100, due to the more complex metal wiring in the array substrate 210, the aperture ratio of the array substrate 210 cannot be further improved, and thus the transmittance improvement of the current display module 100 is limited; however, the present application sets a dimming structure 500 corresponding to the shading layer 223 on the side of the first polarizer 300 away from the display surface to guide the light incident on the non-transparent area NTS to the transparent area TS, that is, without increasing the aperture ratio of the array substrate 210, the dimming structure 500 of the present application can increase the amount of light incident on the transparent area TS, thereby improving the transmittance of the display module 100 and further improving the display effect of the display module 100.

[0055] The technical solution of the present application is now described in conjunction with specific embodiments.

[0056] See also Figure 2 The display panel 200 may include an array substrate 210, a color filter substrate 220 arranged on one side of the array substrate 210, and a liquid crystal layer LC arranged between the array substrate 210 and the color filter substrate 220; the array substrate 210 may be a conventional array substrate 210 or a COA (Color filter On Array, a substrate with a color filter layer arranged on an array), and the present application does not make any specific restrictions.

[0057] For example, when the array substrate 210 of the present application is a conventional array substrate, the light shielding layer 223 of the present application may be located on the color filter substrate 220, such as Figure 2 When the array substrate 210 of the present application is a COA substrate, the light shielding layer 223 of the present application may be located on the array substrate 210, such as Figure 3 The structure shown in the following embodiments is Figure 2 The structure of is used as an example to illustrate.

[0058] In this embodiment, the array substrate 210 may include a first substrate 211 and an array layer 212 located on the first substrate 211, and the array layer 212 may include a plurality of thin film transistors. The thin film transistor may be an etch barrier type, a back channel etch type, or may be divided into a bottom gate thin film transistor, a top gate thin film transistor, and the like structure according to the position of the gate electrode and the active layer.

[0061] See also Figure 2 The display panel 200 further includes a spacer layer PS disposed between the array substrate 210 and the color filter substrate 220 , and the spacer layer PS is used to adjust the cell spacing of the display module 100 .

[0062] See also Figure 2 The color filter substrate 220 may include a second substrate 221, a color resist layer 222 located on the second substrate 221, a light shielding layer 223 arranged on the same layer as the color resist layer 222, and a common electrode layer 224 located on a side of the color resist layer 222 away from the second substrate 221. The color resist layer 222 and the light shielding layer 223 constitute a color filter layer CF. The electric field formed by the common electrode layer 224 and the pixel electrode layer 212f drives the liquid crystal molecules in the liquid crystal layer LC in the display module 100 to deflect.

[0063] See also Figure 4The light-shielding layer 223 may include a plurality of first light-shielding strips 223a and a plurality of second light-shielding strips 223b, the first light-shielding strips 223a extend along the extension direction of the scan line Scan, the second light-shielding strips 223b extend along the extension direction of the data line Data, the plurality of first light-shielding strips 223a and the plurality of second light-shielding strips 223b are cross-arranged and have a mesh structure.

[0064] In this embodiment, since the data line Data and the scan line Scan are in the non-display area, the light shielding layer 223 of the present application needs to shield the data line Data and the scan line Scan. A first light shielding bar 223a corresponds to a scan line Scan, and the positive projection of the scan line Scan on the light shielding layer 223 is located in the corresponding first light shielding bar 223a; a second light shielding bar 223b corresponds to a data line Data, and the positive projection of the data line Data on the light shielding layer 223 is located in the corresponding second light shielding bar 223b.

[0065] It should be noted that the data line Data of the present application can be adaptively set according to the shape of the pixel electrode, for example Figure 4 The scan lines Scan and the data lines Data in the figure may be metal lines that are crisscrossed horizontally and vertically. For other special-shaped pixel electrodes, the data lines Data may be parallel to the edges of the corresponding special-shaped pixel electrodes.

[0066] See also Figure 4 The color-resist layer 222 includes a plurality of color-resist units 222a arranged at intervals, and the plurality of color-resist units 222a are embedded between the plurality of first light-shielding strips 223a and the plurality of second light-shielding strips 223b.

[0067] See also Figure 4 The multiple color resist units 222a may include multiple red color resists R, multiple green color resists G and multiple blue color resists B. The red color resists R, the green color resists G and the blue color resists B are a repeating unit and are repeatedly arranged in the extension direction of the scan line Scan, and in the extension direction of the data line Data, the colors of the color resist units 222a in each column are the same.

[0068] It should be noted that Figure 4 The arrangement of the middle color resist unit 222 a is only one embodiment of the present application.

[0069] See also Figure 1 The display module 100 further includes a second polarizer 400 disposed on a side of the second substrate 221 away from the array substrate 210 , and the polarization axes of the first polarizer 300 and the second polarizer 400 are perpendicular.

[0070] See also Figure 5The first polarizer 300 includes a polarizing layer 301 and a first protective layer 302 disposed on a side of the polarizing layer 301 away from the display panel 200. The dimming structure 500 includes a plurality of grooves 510. The plurality of grooves 510 are disposed on a side of the first protective layer 302 away from the polarizing layer 301, and the plurality of grooves 510 are recessed in a surface of the first protective layer 302 on a side close to the polarizing layer 301.

[0071] In this embodiment, the first polarizer 300 may further include an adhesive layer 303 arranged between the first substrate 211 and the polarizing layer 301, and a second protective layer 304 arranged between the adhesive layer 303 and the polarizing layer 301; the present application may form a plurality of grooves 510 on the first protective layer 302, and the plurality of grooves 510 correspond to a plurality of first shading strips 223a and / or second shading strips 223b in the shading layer 223, and the plurality of grooves 510 guide the incident light corresponding to the shading layer 223 to the area corresponding to the color resistance unit 222a, that is, without increasing the aperture ratio of the array substrate 210, the setting of the dimming structure 500 of the present application increases the amount of light incident on the display area, improves the transmittance of the display module 100, and thereby improves the display effect of the display module 100.

[0072] In this embodiment, the depth of the groove 510 is less than the thickness of the first protective layer 302 to prevent the polarizing layer 301 from being exposed, thereby preventing the polarizing layer 301 from being abnormal.

[0073] In this embodiment, the groove 510 has a first sidewall 510 a and a second sidewall 510 b on the first protection layer 302 . The first sidewall 510 a is a plane or a curved surface, and the second sidewall 510 b is a plane or a curved surface.

[0074] In the present embodiment, at least one of the first sidewall 510 a or the second sidewall 510 b guides the light incident on the non-transparent area NTS to the transparent area TS.

[0075] In this embodiment, the cross-sectional shape of the groove 510 in the width direction is an axisymmetric shape, for example Figure 5 The first side wall 510a and the second side wall 510b are both planes, and the cross-sectional shape is an isosceles triangle; for example Figure 6 The first side wall 510a and the second side wall 510b are both arc surfaces, and the cross-sectional shape can be semicircular or semi-elliptical. Figure 5 and Figure 6 The first side wall 510a and the second side wall 510b can both guide the light incident on the non-light-transmitting area NTS to the light-transmitting area TS.

[0076] In this embodiment, the cross-sectional shape of the groove 510 in the width direction is a non-axisymmetric shape, for example Figure 7The first side wall 510a and the second side wall 510b are both planes, and the first side wall 510a is perpendicular to the surface of the first protective layer 302 away from the array substrate 210, and the cross-sectional shape is a right triangle; for example Figure 8 The first side wall 510a is a plane, the second side wall 510b is an arc surface, and the first side wall 510a is perpendicular to the surface of the first protective layer 302 away from the array substrate 210, and the cross-sectional shape is a special-shaped shape; Figure 7 and Figure 8 The second side wall 510b may guide the light incident to the non-transparent area NTS to the transparent area TS.

[0077] Below Figure 5 and Figure 7 Taking the structure in FIG. 5 as an example, the dimming principle of the groove 510 of the present application is described. Figure 5 In the structure of , the light incident on the first side wall 510a is refracted by the first side wall 510a and directed to the display area close to the side where the second side wall 510b is located, and the light incident on the second side wall 510b is refracted by the second side wall 510b and directed to the display area close to the side where the first side wall 510a is located; Figure 7 In the structure, the light incident on the second side wall 510b is refracted by the second side wall 510b and directed to the display area on the side close to the first side wall 510a. However, since the first side wall 510a is perpendicular to the surface of the first protective layer 302 away from the array substrate 210, it cannot play a dimming role.

[0078] In this embodiment, Figure 5 and Figure 7 The grooves 510 in the embodiment have the function of dimming. Figure 5 The groove 510 in the embodiment can guide the light incident on the groove 510 to the display areas on both sides of the groove 510, thus Figure 6 compared to, Figure 5 The dimming uniformity of the structure is better than Figure 7 The structure in .

[0079] It should be noted that the dimming structure 500 of the present application is described only by taking the groove 510 as an example, and the dimming structure 500 may also be other film layer structures having a dimming effect.

[0080] Since the plurality of grooves 510 of the present application corresponds to the plurality of first light-shielding strips 223 a and / or second light-shielding strips 223 b in the light-shielding layer 223 , different positions of the grooves 510 are described below.

[0081] In this embodiment, the orthographic projection of the dimming structure 500 on the first substrate 211 may partially overlap with the orthographic projection of the light shielding layer 223 on the first substrate 211 .

[0082] See also Fig. 9 The plurality of grooves 510 may include a plurality of first grooves 511 , a first groove 511 corresponds to a first light shielding strip 223 a , and an orthographic projection of the first groove 511 on the light shielding layer 223 is located within the corresponding first light shielding strip 223 a .

[0083] In this embodiment, the first groove 511 extends along the extension direction of the scan line Scan. For example, the first groove 511 may be in a strip shape, or a first light shielding strip 223a is disposed corresponding to a plurality of first grooves 511 in the extension direction of the scan line Scan.

[0084] In this embodiment, the orthographic projection of the first groove 511 on the shading layer 223 can be located within the corresponding first shading strip 223a, that is, the width L1 of the first groove 511 is less than or equal to the width L2 of the first shading strip 223a; and the width of the first shading strip 223a of the present application is larger, that is, the first groove 511 is set with sufficient width to allow more light incident on the first shading strip 223a to be directed to the display area, thereby improving the transmittance of the display module 100 and further improving the display effect of the display module 100.

[0085] In this embodiment, in order to improve the dimming uniformity of the dimming structure 500 , a first groove 511 of the present application corresponds to only one first light shielding strip 223 a , and the number of the first grooves 511 is equal to the number of the first light shielding strips 223 a .

[0086] In this embodiment, due to the influence of the resistance and capacitance of the display module 100, the brightness of the area far away from the signal emitting end is brighter than the brightness of the area close to the signal emitting end. The present application can only set the dimming structure 500 in the area far away from the signal emitting end, that is, the number of first grooves 511 can be smaller than the number of first shading strips 223a, so as to improve the problem of uneven brightness in different areas of the display module 100.

[0087] See also Fig.10 The dimming structure 500 includes a plurality of second grooves 512 , a second groove 512 corresponds to a second light shielding strip 223 b , and an orthographic projection of the second groove 512 on the light shielding layer 223 has an overlapping portion with the corresponding first light shielding strip 223 a .

[0088] In this embodiment, the second groove 512 extends along the extension direction of the data line Data. For example, the second groove 512 may be in a strip shape, or a second light shielding strip 223 b is disposed corresponding to a plurality of second grooves 512 in the extension direction of the data line Data.

[0089] In this embodiment, since the width L2 of the first light-shielding strip 223a is greater than the width L3 of the second light-shielding strip 223b, in order to avoid the second groove 512 from overlapping with the adjacent color-resistance unit 222a, the present application can reduce the width L4 of the second groove 512 so that the orthographic projection of the second groove 512 on the light-shielding layer 223 is located within the corresponding second light-shielding strip 223b, that is, the width L4 of the second groove 512 can be less than or equal to the width L3 of the second light-shielding strip 223b, and the width L4 of the second groove 512 is less than the width L1 of the first groove 511.

[0090] In this embodiment, that is, in the extending direction of the scan line Scan, at least one color resist unit 222a is disposed between two adjacent second grooves 512. Fig.11 The number of the second grooves 512 may be the same as the number of the second shading strips 223 b , that is, the second grooves 512 correspond to the second shading strips 223 b one by one, and a color resist unit 222 a is arranged between two adjacent second grooves 512 .

[0091] Alternatively, see Fig.10 The number of the second grooves 512 may be smaller than the number of the second light shielding strips 223 b. For example, in the extending direction of the scan line Scan, three color resist units 222 a are arranged between two adjacent second grooves 512 .

[0092] In this embodiment, the width of the second groove 512 of the present application can also be greater than the width of the second light shielding strip 223b, that is, the second groove 512 overlaps with the corresponding second light shielding strip 223b and extends toward the display area. For example, in the extension direction of the scan line Scan, the second groove 512 has an overlapping portion with at least one of the two adjacent color resist units 222a; see Fig.12 , the second groove 512 has an overlapping portion with an adjacent color resist unit 222a; see Fig.13 , the second groove 512 may have overlapping portions with two adjacent color resist units 222a.

[0093] exist Fig.13In the structure, the second groove 512 and the green color resist G have a first overlapping portion OL1, and the second groove 512 and the blue color resist B have a second overlapping portion OL2. Since the incident light corresponding to the first overlapping portion OL1 is directed to the blue color resist B, the incident light corresponding to the second overlapping portion OL2 is directed to the green color resist G, and the incident light corresponding to the second shading strip 223b is compensated to the green color resist G and the blue color resist B, respectively, even if the second groove 512 has an overlapping portion with the adjacent color resist unit 222a, the technical solution of the present application can ensure the brightness uniformity of the display module 100; at the same time, the increase in the width of the second groove 512 reduces the process difficulty and reduces the cost of the display module 100.
