It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0047] Figure 1 is a plan view of a display module provided by the present disclosure, Figure 2 yes Figure 1A cross-sectional view of the display module along the line AA', referring to Figure 1 and Figure 2 , an embodiment of the present disclosure provides a display module, the display module comprising:
[0048] Light emitting module 10;
[0049] The anti-peeping component 20 is located at the light-emitting side of the light-emitting module 10. The anti-peeping component 20 includes an anti-peeping layer 30 and a dimming layer 40. The dimming layer 40 is located between the anti-peeping layer 30 and the light-emitting module 10.

[0051] The dimming layer 40 includes multiple dimming units 41, one dimming unit 41 corresponds to at least one baffle wall 31, the vertical projection of the dimming unit 41 on the plane where the light-emitting module 10 is located and the vertical projection of the corresponding baffle wall 31 on the plane where the light-emitting module 10 is located at least partially overlap, and the dimming unit 41 is used to change the path of at least part of the light emitted toward the baffle wall 31 so that the part of the light is emitted toward the light-transmitting portion 32.
[0052] Specifically, the display module provided by the embodiment of the present disclosure includes a light-emitting module 10 and an anti-peeping component 20, wherein the anti-peeping component 20 is arranged on the light-emitting side of the light-emitting module 10. Optionally, when the display module is a liquid crystal display module, the light-emitting module 10 can be a backlight source; the display module also includes a liquid crystal display panel, which is located on the light-emitting side of the backlight source, and the anti-peeping component 20 can be arranged on both sides of the liquid crystal display panel in a direction perpendicular to the plane where the backlight source is located. For example, the anti-peeping component 20 can be arranged between the backlight source and the liquid crystal display panel, or on the side of the liquid crystal display panel away from the backlight source. Optionally, when the display module is an organic light-emitting display module or a micro-luminescent display module, the light-emitting module 10 is an organic light-emitting display panel, and the anti-peeping component 20 is arranged on the light-emitting side of the organic light-emitting display panel.
[0053] It should be noted that in other embodiments of the present disclosure, the light-emitting module 10 can also be other light-emitting devices, and the anti-peeping component 20 can also be used to be arranged on the light-emitting side of other light-emitting devices, which will not be described in detail in the present disclosure.
[0054] The anti-peeping component 20 includes an anti-peeping layer 30, and the anti-peeping layer 30 includes a plurality of baffles 31, and a light-transmitting portion 32 is provided between adjacent baffles 31. Among them, the material of the light-transmitting portion 32 is a transparent material. The baffle 31 is a black light-absorbing structure, and the light incident on the baffle 31 can be absorbed. Optionally, the baffle 31 can be a graphic adhesive layer mixed with a black additive. The black additive can be carbon powder or other black material powder. The light incident on the anti-peeping layer 30 is propagated based on the light-transmitting portion 32 between adjacent baffles 31, thereby limiting the transmission direction and transmission angle of the light emitted through the anti-peeping layer 30, so that the display module has an anti-peeping function.
[0055] Part of the light directed to the anti-peeping component 20 is directly directed to the light-transmitting portion 32, and part of the light is directed to the surface 311 of the baffle 31 close to the light-emitting module 10. The anti-peeping component 20 further includes a dimming layer 40, which is located between the anti-peeping layer 30 and the light-emitting module 10, that is, the light emitted by the light-emitting module 10 is directed to the anti-peeping layer 30 through the dimming layer 40. The dimming layer 40 includes a plurality of dimming units 41, one dimming unit 41 corresponds to at least one baffle 31, a vertical projection of the dimming unit 41 on the plane where the light-emitting module 10 is located and a vertical projection of the corresponding baffle 31 on the plane where the light-emitting module 10 is located at least partially overlap, and the dimming unit 41 is used to change the path of at least part of the light emitted toward the baffle 31 so that the part of the light is emitted toward the light-transmitting portion 32, that is, through the setting of the dimming unit 41, the path of part of the light originally emitted toward the surface 311 of the baffle 31 close to the light-emitting module 10 is changed, so that the part of the light is emitted toward the light-transmitting portion 32, which is beneficial to increase the amount of light emitted into the light-transmitting portion 32, thereby helping to improve the transmittance of light, improve the display brightness, and improve the display effect.
[0056] Continue to refer Figure 1 and Figure 2 , in some optional embodiments, the dimming unit 41 includes a first dimming unit 411;
[0057] Along a direction perpendicular to the plane where the light-emitting module 10 is located, a surface located at least on one side of the first dimming unit 411 includes a first curved portion 4111, the first curved portion 4111 is concave toward the inside of the dimming layer 40, and the first curved portion 4111 forms a concave lens;
[0058] The vertical projection of the surface 311 of the retaining wall 31 close to the light emitting module 10 on the plane where the light emitting module 10 is located and the vertical projection of the corresponding first curved surface portion 4111 on the plane where the light emitting module 10 is located at least partially overlap.
[0059] Specifically, the dimming unit 41 includes a first dimming unit 411. Along the direction perpendicular to the plane where the light-emitting module 10 is located, the surface located at least on one side of the first dimming unit 411 includes a first curved surface portion 4111. The first curved surface portion 4111 is recessed toward the inside of the dimming layer 40. The first curved surface portion 4111 forms a concave lens, which has a divergent effect on light. The vertical projection of the surface of the side of the blocking wall 31 close to the light-emitting module 10 on the plane where the light-emitting module 10 is located and the vertical projection of the corresponding first curved surface portion 4111 on the plane where the light-emitting module 10 is located at least partially overlap, so that the light originally directed to the surface 311 of the side of the blocking wall 31 close to the light-emitting module 10 is diverged by the first curved surface portion 4111, and part of the light will change the path and be directed to the light-transmitting portion 32, which is conducive to increasing the amount of light entering the light-transmitting portion 32, thereby facilitating the light transmittance, display brightness, and display effect.
[0060] It should be noted that Figure 2 The first curved surface 4111 is only exemplarily shown in FIG. 4 . In other embodiments of the present disclosure, for example, reference is made to FIG. Figure 3 , Figure 3 yes Figure 1 Another cross-sectional view of the display module along the line AA', in the direction perpendicular to the plane where the light-emitting module 10 is located, the surfaces on both sides of the first dimming unit 411 can be provided with the first curved surface 4111; exemplarily, refer to Figure 4 , Figure 4 yes Figure 1 In another cross-sectional view of the display module along line AA′, the first curved portion 4111 may also be disposed only on the surface of the dimming layer 40 away from the anti-peep layer 30 , which will not be described in detail in the present disclosure.
[0061] Continue to refer Figure 1 and Figure 2 , in some optional embodiments, the retaining walls 31 are arranged along the first direction X;
[0062] The width of the first curved surface portion 4111 along the first direction X is less than or equal to the width of the surface 311 of the corresponding retaining wall 31 close to the light emitting module 10 along the first direction X.
[0063] Specifically, the retaining walls 31 are arranged along the first direction X, the width of the first curved surface portion 4111 along the first direction X is designed to be L3, and the width of the surface 311 of the retaining wall 31 corresponding to the first curved surface portion 4111 on the side close to the light-emitting module 10 along the first direction X is L4, L3 is less than or equal to L4, that is, the vertical projection of the first curved surface portion 4111 on the plane where the light-emitting module 10 is located and the vertical projection of the surface 311 of the retaining wall 31 corresponding to the first curved surface portion 4111 on the side close to the light-emitting module 10 on the plane where the light-emitting module 10 is located at least partially overlap, and the first curved surface portion 4111 on the light-emitting module 10 The vertical projection of the plane in which it is located does not overlap with the vertical projection of the surface 321 of the light-transmitting portion 32 on the side close to the light-emitting module 10 on the plane in which the light-emitting module 10 is located, so that the first curved surface portion 4111 can diverge the light originally emitted to the surface 311 of the baffle wall 31 close to the light-emitting module 10. At the same time, the influence of the setting of the first curved surface portion 4111 on the light originally emitted to the light-transmitting portion 32 is avoided, which is beneficial to increase the amount of light incident on the light-transmitting portion 32, thereby helping to improve the transmittance of light, improving the display brightness, and improving the display effect.
[0064] It should be noted that the radius of curvature of the first curved surface portion 4111 and the height of the first curved surface portion 4111 in a direction perpendicular to the plane where the light-emitting module 10 is located can be set according to actual production requirements, and the present disclosure does not make specific limitations on this.
[0065] It should be noted that Figure 1 and Figure 2 The retaining wall 31 is exemplarily shown to be arranged along the first direction X. In other embodiments of the present disclosure, the retaining wall 31 may also be other structures. For example, refer to Figure 5 , Figure 5 It is a plan view of another display module provided by the present disclosure. The retaining wall 31 may also be a grid structure, which will not be described in detail in the present disclosure.
[0066] Figure 6 yes Figure 1 Another cross-sectional view of the display module along line AA', see Figure 1 and Figure 6 , in some optional embodiments, the dimming unit 41 includes a second dimming unit 412;
[0067] Along a direction perpendicular to the plane where the light-emitting module 10 is located, a surface located at at least one side of the second dimming unit 412 includes a second curved portion 4121, the second curved portion 4121 bulges in a direction away from the inside of the dimming layer 40, and the second curved portion 4121 forms a convex lens;
[0068] The vertical projection of the second curved portion 4121 on the plane where the light-emitting module 10 is located and the vertical projection of the light-transmitting portion 32 on the plane where the light-emitting module 10 is located at least partially overlap, and the vertical projection of the second curved portion 4121 on the plane where the light-emitting module 10 is located and the vertical projection of the surface 311 of the retaining wall 31 on the side close to the light-emitting module 10 on the plane where the light-emitting module 10 is located at least partially overlap.
[0069] Specifically, the dimming unit 41 includes a second dimming unit 412. Along a direction perpendicular to the plane where the light-emitting module 10 is located, the surface on at least one side of the second dimming unit 412 includes a second curved surface portion 4121. The second curved surface portion 4121 protrudes in a direction away from the interior of the dimming layer 40. The second curved surface portion 4121 forms a convex lens, which has the effect of converging light. The vertical projection of the second curved surface portion 4121 on the plane where the light-emitting module 10 is located and the vertical projection of the light-transmitting portion 32 on the plane where the light-emitting module 10 is located at least partially overlap, and the vertical projection of the second curved surface portion 4121 on the plane where the light-emitting module 10 is located and the vertical projection of the surface 311 of the side of the blocking wall 31 close to the light-emitting module 10 on the plane where the light-emitting module 10 is located at least partially overlap, that is, the second curved surface portion 4121 can converge the light incident on the light-entering side of the anti-peep layer 30 toward the normal direction close to the second curved surface portion 4121, and the normal of the second curved surface portion 4121 extends through the area corresponding to the light-transmitting portion 32, so that the second curved surface portion 4121 can change the path of part of the light originally emitted to the surface 311 of the side of the blocking wall 31 close to the light-emitting module 10, so that part of the light is emitted to the light-transmitting portion 32, which is beneficial to increase the amount of light emitted into the light-transmitting portion 32, thereby facilitating the improvement of the light transmittance, the display brightness, and the display effect. In addition, when the baffle 31 is made of light-absorbing material, part of the light that can originally enter the light-transmitting portion 32 will eventually be absorbed by the baffle 31 due to the larger angle and cannot be emitted. However, in the embodiment of the present application, the second curved surface portion 4121 overlaps with the light-transmitting portion 32, which can further reduce the angle of the above-mentioned light and increase the amount of light that can be emitted, thereby improving the display brightness.
[0070] It should be noted that Figure 6 The second curved surface 4121 is only exemplarily shown in FIG. 4 . In other embodiments of the present disclosure, for example, reference is made to FIG. Figure 7 , Figure 7 yes Figure 1 In another cross-sectional view of the display module along line AA', along a direction perpendicular to the plane where the light-emitting module 10 is located, the surfaces on both sides of the first dimming unit 411 can be provided with a second curved surface 4121; exemplarily, refer to Figure 8 , Figure 8 yes Figure 1In another cross-sectional view of the display module along line AA′, the second curved portion 4121 may also be disposed only on the surface of the dimming layer 40 away from the anti-peep layer 30 , which will not be described in detail in the present disclosure.
[0071] Continue to refer Figure 1 and Figure 6 , in some optional embodiments, the retaining walls 31 are arranged along the first direction X;
[0072] The width of the second curved surface portion 4121 along the first direction X is L1, and the distance between the centers of the surfaces 311 of two adjacent retaining walls 31 close to the light-emitting module 10 along the first direction X is L2;
[0073] Among them, L1≤L2.
[0074] Specifically, the retaining walls 31 are arranged along the first direction X, and the width of the second curved surface portion 4121 along the first direction X is designed to be less than or equal to the distance along the first direction X between the centers of the surfaces 311 of the two adjacent retaining walls 31 close to the light-emitting module 10, that is, the vertical projection of the second curved surface portion 4121 on the plane where the light-emitting module 10 is located and the vertical projection of the surface 311 of the retaining wall 31 close to the light-emitting module 10 on the plane where the light-emitting module 10 is located at least partially overlap, and the normal of the second curved surface portion 4121 extends through the area corresponding to the light-transmitting portion 32, so that the second curved surface portion 4121 can change the path of part of the light originally emitted to the surface 311 of the retaining wall 31 close to the light-emitting module 10, so that part of the light is emitted to the light-transmitting portion 32. At the same time, the second curved surface portion 4121 can correspond one-to-one with the light-transmitting portion 32, and the settings of adjacent second curved surface portions 4121 do not affect each other.
[0075] It should be noted that the radius of curvature of the second curved surface portion 4121 and the height of the second curved surface portion 4121 in a direction perpendicular to the plane where the light-emitting module 10 is located can be set according to actual production requirements, and the present disclosure does not make specific limitations on this.
[0076] Continue to refer Figure 1 and Figure 2 In some optional embodiments, the anti-peeping component 20 further includes a first substrate 51 and a second substrate 52 that are arranged opposite to each other, the first substrate 51 is located between the anti-peeping layer 30 and the dimming layer 40 , and the second substrate 52 is located on a side of the anti-peeping layer 30 away from the light-emitting module 10 .
[0077] Specifically, the anti-peeping component 20 further includes a first substrate 51 and a second substrate 52 that are arranged opposite to each other. In a direction perpendicular to the plane where the light-emitting module 10 is located, the first substrate 51 and the second substrate 52 are respectively located on both sides of the anti-peeping layer 30, and the second substrate 52 is located on the side of the anti-peeping layer 30 away from the light-emitting module 10. The first substrate 51 and the second substrate 52 can support and protect the anti-peeping layer 30, ensuring the structural stability of the anti-peeping layer 30 and extending the service life. The first substrate 51 is located between the anti-peeping layer 30 and the dimming layer 40, that is, the dimming layer 40 can be bonded to the side of the first substrate 51 away from the anti-peeping layer 30, so that the dimming layer 40 can be set in the anti-peeping component 20.
[0078] It should be noted that the dimming layer 40 can be directly and fully bonded to the surface of the first substrate 51 away from the anti-peep layer 30, and an air layer can also be provided between the dimming layer 40 and the first substrate 51, which will not be elaborated in the present disclosure.
[0079] It should be noted that Figure 2 exemplarily shows the structure of the display module when the dimming layer 40 includes the first dimming unit 411. In other embodiments of the present disclosure, the dimming layer 40 may also include the second dimming unit 412. In this case, the structure of the display module may refer to Figure 6 , this disclosure will not be repeated here.

The first substrate 51 is located on the side of the dimming layer 40 away from the light-emitting module 10. The dimming layer 40 can be bonded to the side of the anti-peeping layer 30 away from the first substrate 51, so that the dimming layer 40 can be set in the anti-peeping component 20. The second substrate 52 is located on the side of the anti-peeping layer 30 away from the light-emitting module 10.

The provision of the isolation layer 61 is beneficial to increasing the distance between the dimming layer 40 and the anti-peep layer 30, so that the light originally emitted by the light-emitting module 10 and directed toward the surface 311 of the baffle wall 31 close to the light-emitting module 10 changes its path through the dimming unit 41, so that more light is directed toward the light-transmitting portion 32, which is beneficial to increase the amount of light entering the light-transmitting portion 32, thereby helping to improve the transmittance of light, improve the display brightness, and improve the display effect.
[0088] It should be noted that Fig.11 exemplarily shows the structure of the display module when the dimming layer 40 includes the first dimming unit 411.

The dimming unit 41 includes a third dimming unit 413. At least part of the light originally emitted to the surface 311 of the baffle wall 31 close to the light-emitting module 10 is first emitted to the interface between the third dimming unit 413 and the first substrate 51. Since the refractive index of the third dimming unit 413 is smaller than the refractive index of the first substrate 51, part of the light originally emitted to the surface 311 of the baffle wall 31 close to the light-emitting module 10 is refracted and deflected toward the direction close to the light-transmitting portion 32, so that the light originally emitted to the surface 311 of the baffle wall 31 close to the light-emitting module 10 is emitted to the light-transmitting portion 32, which is beneficial to increase the amount of light emitted into the light-transmitting portion 32, thereby facilitating the improvement of the light transmittance, the display brightness, and the display effect.

Of course, the cross-section of the third dimming unit 413 can also be other shapes such as a triangle, an inverted trapezoid, and an inverted triangle, which will not be described in detail in the present disclosure.

Since the refractive index of the third dimming unit 413 is less than the refractive index of the first substrate 51, part of the light originally emitted to the surface 311 of the baffle wall 31 close to the light-emitting module 10 is refracted and deflected toward the direction close to the light-transmitting portion 32, so that the light originally emitted to the surface 311 of the baffle wall 31 close to the light-emitting module 10 is emitted to the light-transmitting portion 32, which is beneficial to increase the amount of light entering the light-transmitting portion 32, thereby facilitating the improvement of the light transmittance, the display brightness, and the display effect.

The refractive index of the dimming part 42 is different from the refractive index of the third dimming unit 413, so that when the light is incident on the interface between the third dimming unit 413 and the dimming part 42, the light will be refracted, so that more light enters the light-transmitting part 32, so as to increase the amount of light entering the light-transmitting part 32, so as to improve the transmittance of light, improve the display brightness, and improve the display effect.

At least part of the light can be emitted into the light-transmitting portion 32, which is beneficial to increase the amount of light emitted into the light-transmitting portion 32, thereby helping to improve the transmittance of light, and thus helping to improve the display brightness and the display effect.
