[0030] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. The described technical solutions are only used to explain and illustrate the idea of the present application, and should not be regarded as a limitation on the protection scope of the present application.

[0031] In the description of the present application, it should be understood that terms such as "first", "second" and similar words do not denote any order, quantity or importance, but are only used to distinguish different technical features. Terms such as "a plurality of" and similar words mean two or more, unless otherwise clearly defined.

[0032] "A and / or B" includes the following three combinations: only A, only B, and the combination of A and B.

[0033] The use of "suitable for" or "configured to" in the present application means open and inclusive language, which does not exclude devices suitable for or configured to perform additional tasks or steps. In addition, the use of "based on" means open and inclusive, because a process, step, calculation or other action "based on" one or more of the stated conditions or values can in practice be based on additional conditions or values beyond the stated ones.

[0034] In the present application, the term "exemplary" is used to mean "serving as an example, illustration, or description". Any embodiment described as "exemplary" in the present application is not necessarily to be construed as more preferred or advantageous than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application.

[0035] The various embodiments of the present application are similar, and the features in different embodiments and / or different examples can be combined with each other.

[0036] Based on this, some embodiments of the present application provide a display module, as Figures 1 to 8 shown, the display module 100 includes: a display component 10 and a dimming component 20.

[0037] The display component 10 includes a carrier substrate 11 and a black matrix 12 located on the carrier substrate 11. The black matrix 12 has a plurality of openings K for emitting light.

[0038] The dimming component 20 is located on the light-emitting side of the display component 10. The dimming component 20 includes a first electrode layer 21, a dimming layer 22, and a second electrode layer 23 that are sequentially arranged in a direction away from the display component 10. The dimming layer 22 has a dimming area T1 and a plurality of light-transmitting areas T2. The dimming layer 22 includes a dimming portion 221 located in the dimming area T1. The dimming portion 221 has a first light transmittance when the first electrode layer 21 and the second electrode layer 23 are at a first voltage difference, and has a second light transmittance when the first electrode layer 21 and the second electrode layer 23 are at a second voltage difference. Wherein, the first voltage difference and the second voltage difference are different, and the first light transmittance and the second light transmittance are different. In this case, the light transmittance of the dimming portion 221 can change with the change of the voltage difference between the first electrode layer 21 and the second electrode layer 23. Thus, the light transmittance of the dimming portion 221 can be adjusted by changing the voltage difference between the first electrode layer 21 and the second electrode layer 23, and further the switching of different display states of the display module can be realized.

[0039] As an example, when the first electrode layer 21 and the second electrode layer 23 are at a first voltage difference, the dimming portion 221 has a relatively large light transmittance. As Figure 2 shown, when the light passes through the dimming portion 221, it can be emitted in substantially the original direction. At this time, the display module 100 has a relatively large light-emitting angle. Whether it is a user in the front-view position or a user in the side-view (oblique-view) position, they can receive the light from the display module 100 and thus view the content displayed in the display module 100. At this time, the display module 100 is in the normal-view display state, that is, the display module 100 is in the shared state.

[0040] When the first electrode layer 21 and the second electrode layer 23 are at a second voltage difference, the dimming portion 221 has a relatively small light transmittance. As Figure 3 shown, the light passing through the dimming portion 221 is scattered or absorbed, and the light that does not pass through the dimming portion 221 is emitted in substantially the original direction. At this time, the display module 100 has a relatively small light-emitting angle. Therefore, only a user in the front-view position can view the content displayed in the display module 100. At this time, the display module 100 is in the anti-peeping state.

[0041] It should be noted that the first voltage difference and the second voltage difference can be adjusted as needed, as long as it is ensured that the first light transmittance of the light-dimming part 221 under the first voltage difference is different from the second light transmittance of the light-dimming part 221 under the second voltage difference. In addition, when the first electrode layer 21 and the second electrode layer 23 are adjusted within a certain voltage difference range, the light-dimming part 221 can exhibit multiple light transmittances, and the first light transmittance can be the largest one among the multiple light transmittances, and the second light transmittance can be the smallest one among the multiple light transmittances. This can make the difference between the anti-peeping state and the sharing state of the display module 100 obvious, so as to ensure the user experience.

[0042] In this embodiment, each opening K exposes a light-transmitting area T2. In this case, when the display module 100 is in the anti-peeping state, the black matrix 12 and the light-dimming part 221 are jointly used to control the light-emitting angle of the display module 100, so that the problem of increased thickness caused by too many film layers in the display module 100 can be avoided. On the other hand, since each opening K exposes a corresponding light-transmitting area T2, the main-viewing-angle light emitted successively through the opening K and the corresponding light-transmitting area T2 can bypass the light-dimming part 221, thereby effectively avoiding large losses when the main-viewing-angle light passes through the light-dimming part 221. Furthermore, the display module 100 has a high display brightness when in the anti-peeping state, so that the problem of eye fatigue of the user when using the display module 100 to implement the anti-peeping function can be effectively avoided.

[0043] In some examples, such as Figure 1 shown, the orthographic projection of the light-transmitting area T2 on the carrier substrate 11 overlaps with the orthographic projection of the corresponding opening K on the carrier substrate 11. In this case, along a cross-sectional direction, the shape and size of the light-transmitting area T2 are respectively the same as those of the corresponding opening K, and this cross-sectional direction is perpendicular to the thickness direction of the carrier substrate 11.

[0044] In other examples, such as Figure 4 shown, the orthographic projection of the light-transmitting area T2 on the carrier substrate is within the orthographic projection of the corresponding opening K on the carrier substrate 11. In this case, there is a distance between the edge of the orthographic projection of the light-transmitting area T2 on the carrier substrate and the edge of the orthographic projection of the corresponding opening K on the carrier substrate 11, and the edge of the orthographic projection of the opening K on the carrier substrate 11 surrounds the edge of the orthographic projection of the light-transmitting area T2 on the carrier substrate.

[0045] By setting the orthographic projection of the light-transmitting area T2 on the carrier substrate within the range of the orthographic projection of the corresponding opening K on the carrier substrate 11, the dimming part 221 can block the opening K to a certain extent. In this case, when the display module 100 is in the anti-peeping state, due to the blocking of the dimming part 221, the light angle emitted from the display module 100 can be further narrowed, thereby improving the contrast of the display module 100.

[0046] As an example, along a cross-sectional direction, the shape of the light-transmitting area T2 is the same as that of the corresponding opening K, and the size of the light-transmitting area T2 is larger than that of the corresponding opening K. This cross-sectional direction is perpendicular to the thickness direction of the carrier substrate 11.

[0047] In some examples, the central axis of the light-transmitting area T2 coincides with the central axis of the opening K, so as to achieve a better light-emitting effect.

[0048] In some embodiments, the dimming part 221 includes polymer-dispersed liquid crystal. The polymer-dispersed liquid crystal is in a first state with a first light transmittance under a first voltage difference and is in a second state with a second light transmittance under a second voltage difference. As an example, under the first voltage difference, the polymer-dispersed liquid crystal is in a transparent state; while under the second voltage difference, the polymer-dispersed liquid crystal is in a fogged state. At this time, light is scattered when passing through the polymer-dispersed liquid crystal, resulting in the second light transmittance of the polymer-dispersed liquid crystal being less than the first light transmittance. In this way, the display module 100 can be flexibly switched between the sharing state and the anti-peeping state.

[0049] As an example, the polymer-dispersed liquid crystal can adopt polymer-stabilized cholesteric liquid crystal molecules.

[0050] In other embodiments, the dimming part 221 includes an electrochromic element. The electrochromic element is in a first state with a first light transmittance under a first voltage difference and is in a second state with a second light transmittance under a second voltage difference. As an example, under the first voltage difference, the electrochromic element is in a transparent state. At this time, the dimming part 221 can directly transmit light, so that the display module 100 is in the sharing state. Under the second voltage difference, the electrochromic element presents a black state (or a dark color system state close to the black state). At this time, light is blocked or absorbed when passing through the electrochromic element, resulting in the second light transmittance of the electrochromic element being less than the first light transmittance. In this way, the display module 100 can be flexibly switched between the sharing state and the anti-peeping state.

[0051] As an example, the electrochromic element may be iridium oxide (IrO2), molybdenum trioxide (MoO3), tungsten trioxide (WO3), etc. Of course, the electrochromic element may also be other electrochromic materials that can exhibit different transparent states and non-transparent states under different voltage differences. This is not elaborated in the embodiments of the present application. During specific implementation, selection can be made according to actual requirements. In addition, the electrochromic element can exhibit different transmittances under different voltage differences, and the transmittances of the electrochromic element under the first voltage difference and the second voltage difference can be selected as needed.

[0052] In some embodiments, please continue to refer to Figures 1 to 8 , the dimming component 20 further includes a cover plate 24, the second electrode layer 23 is disposed on the cover plate 24, and the first electrode layer 21 is disposed on the display component 10.

[0053] Such an arrangement enables the second electrode layer 23 and the first electrode layer 21 to be fabricated on the cover plate 24 and the display component 10 respectively, which is conducive to improving the fabrication efficiency of the display module 100. In addition, since the first electrode layer 21 is disposed on the display component 10, the dimming component 20 and the display component 10 can also share a substrate (such as Figures 1 to 6 the carrier substrate 11 shown), thereby reducing the thickness of the display module 100 and enhancing the user experience.

[0054] In some embodiments, as shown in Figures 1 to 4 , the display component 10 may include a driving substrate 31 and a plurality of light-emitting units 32 electrically connected to the driving substrate 31. The driving substrate 31 can drive the light-emitting units 32 to emit light. Each opening K exposes one light-emitting unit 32, so that the light emitted by the light-emitting unit 32 exits through the opening K to realize the display of the picture.

[0055] In some examples, each light-emitting unit 32 may include one or more light-emitting devices. When each light-emitting unit 32 includes a plurality of light-emitting devices, the plurality of light-emitting devices are used to emit light of different colors, so that the display module 100 can realize the display of a color picture. For example, each light-emitting unit 32 includes light-emitting devices that emit red light, green light, and blue light respectively.

[0056] As an example, the light-emitting device may employ an organic light-emitting diode or an LED (Light-Emitting Diode) chip.

[0057] In some other embodiments, as shown in Figures 5 to 8As shown, the display component 10 may include a liquid crystal display panel. In this case, the display component 10 further includes a backlight 13. The light emitted by the backlight 13 is modulated by the liquid crystal display panel and then exits through the opening K of the black matrix 12 to achieve the display of the picture.

[0058] The display component 10 (such as a liquid crystal display panel) includes a counter substrate 14 and a liquid crystal layer 15 located between the counter substrate 14 and the carrier substrate 11. The liquid crystal layer 15 can be deflected under the drive of different voltages to modulate the light emitted by the backlight 13, thereby achieving the picture display of the display module 100.

[0059] Among them, the carrier substrate 11 is disposed on one side of the liquid crystal layer 15 away from or close to the backlight 13. That is to say, the carrier substrate 11 provided with the black matrix 12 can be on the side farther from the backlight 13 or closer to the backlight 13 compared with the liquid crystal layer 15.

[0060] In some embodiments, when the carrier substrate 11 is disposed on the side of the liquid crystal layer 15 away from the backlight 13, as Figure 5 and Figure 6 shown, the display component 10 (such as a liquid crystal display panel) further includes a plurality of light filtering parts 16 disposed on the counter substrate 14. Among them, each opening K exposes one light filtering part 16.

[0061] As an example, the plurality of light filtering parts 16 include a red light filtering part, a green light filtering part, and a blue light filtering part. Each light filtering part 16 can filter light of a color different from its own color, so that light of the same color as it exits through the opening K.

[0062] In this embodiment, the light filtering part 16 and the black matrix 12 are respectively located on the counter substrate 14 and the carrier substrate 11. In this way, the light filtering part 16 and the black matrix 12 can be manufactured by different devices respectively, and then the counter substrate 14 and the carrier substrate 11 are arranged in alignment, which is beneficial to improving the manufacturing efficiency of the display module 100.

[0063] Exemplarily, the first electrode layer 21 is disposed on the carrier substrate 11. The thickness of the carrier substrate 11 can be 1 / 3 to 1 / 2 of the thickness of the counter substrate 14, which is beneficial to further reducing the thickness of the display module 100 and thus improving the user experience. For example, the thickness of the carrier substrate 11 can be 1 / 3, 5 / 12, or 1 / 2 of the thickness of the counter substrate 14, etc. This embodiment does not limit this.

[0064] In some examples, please continue to refer to Figure 5 and Figure 6, the display module 100 further includes a first signal input terminal 41 and an adapter 51 that are connected to each other. The first signal input terminal 41 is disposed on the carrier substrate 11, and the adapter 51 is connected to the second electrode layer 23.

[0065] By providing the first signal input terminal 41 and the adapter 51, a voltage signal can be input to the second electrode layer 23 through the first signal input terminal 41 and the adapter 51 in sequence. Since both the first electrode layer 21 and the first signal input terminal 41 are located on the carrier substrate 11, this is beneficial to the connection of the signal input terminals in the display module 100.

[0066] As an example, the adapter 51 extends along the thickness direction of the display module 100, and both ends of the adapter 51 are respectively connected to the first signal input terminal 41 and the second electrode layer 23. The material of the adapter 51 can be gold or other conductive materials.

[0067] In some examples, please continue to refer to Figure 5 and Figure 6 , the display module 100 further includes a second signal input terminal 42. The second signal input terminal 42 and the first signal input terminal 41 are disposed on one side of the carrier substrate 11 close to the liquid crystal layer 15. A first via hole H1 and a second via hole H2 are formed in the carrier substrate 11. The first signal input terminal 41 is connected to the adapter 51 through the first via hole H1, and the second signal input terminal 42 is connected to the first electrode layer 21 through the second via hole H2.

[0068] This setting makes the first signal input terminal 41 and the second signal input terminal 42 located on the same side of the carrier substrate 11, thus facilitating their connection to the external signal transmission terminal.

[0069] It should be noted that in this application, A and B are connected through a via hole, which means that A and B are connected through the conductive material in the via hole, and this will not be elaborated hereinafter.

[0070] In some examples, the display component 10 further includes a pixel electrode layer and a common electrode layer 17. The pixel electrode layer and the common electrode layer 17 can be respectively disposed on the counter substrate 14 and the carrier substrate 11, and the liquid crystal layer 15 is located between the pixel electrode layer and the common electrode layer 17. The pixel electrode layer includes a plurality of pixel electrodes, and each pixel electrode is connected to a driving circuit on the counter substrate 14, so as to drive the corresponding liquid crystal molecules in the liquid crystal layer to deflect, thereby modulating the light emitted from the corresponding area.

[0071] In some examples, the common electrode layer 17 can be fabricated on the carrier substrate 11 after the black matrix 12 is completed. The signal input end of the common electrode layer 17, the first signal input end 41, and the second signal input end 42 are located on the same side of the carrier substrate 11, which is beneficial for connecting the above signal input ends to the external signal transmission ends.

[0072] In some embodiments, as Figure 7 and Figure 8 shown, when the carrier substrate 11 is disposed on the side of the liquid crystal layer 15 away from the backlight 13, the display assembly 10 (such as a liquid crystal display panel) further includes a plurality of light filtering portions 16 disposed on the counter substrate 14, wherein each light filtering portion 16 is correspondingly disposed in an opening K.

[0073] With such an arrangement, since the light filtering portion 16 is disposed in the opening K of the black matrix 12, it is beneficial to reduce the thickness of the display module 100, thereby enhancing the user experience.

[0074] In some examples, please continue to refer to Figure 7 and Figure 8 , the display module 100 further includes a first signal input end 41 and an adapter 51 connected to each other. The first signal input end 41 is disposed on the counter substrate 14, and the adapter 51 is connected to the second electrode layer 23.

[0075] By providing the first signal input end 41 and the adapter 51, a voltage signal can be input to the second electrode layer 23 sequentially through the first signal input end 41 and the adapter 51. Since both the first electrode layer 21 and the first signal input end 41 are located on the counter substrate 14, it is beneficial for the connection of the signal input ends in the display module 100.

[0076] As an example, the adapter 51 extends along the thickness direction of the display module 100, and both ends of the adapter 51 are respectively connected to the first signal input end 41 and the second electrode layer 23.

[0077] In some examples, please continue to refer to Figure 7 and Figure 8 , the display module 100 further includes a second signal input end 42. The second signal input end 42 and the first signal input end 41 are disposed on the side of the counter substrate 14 close to the liquid crystal layer 15. The counter substrate 14 is provided with a first via hole H1 and a second via hole H2. The first signal input end 41 is connected to the adapter 51 through the first via hole H1, and the second signal input end 42 is connected to the first electrode layer 21 through the second via hole H2.

[0078] With such an arrangement, the first signal input end 41 and the second signal input end 42 are located on the same side of the counter substrate 14, facilitating their connection to the external signal transmission ends.

[0079] In some examples, the display component 10 further includes a pixel electrode layer and a common electrode layer 17. The pixel electrode layer and the common electrode layer 17 can be respectively disposed on the carrier substrate 11 and the counter substrate 14, and the liquid crystal layer 15 is located between the pixel electrode layer and the common electrode layer 17. In this example, since only the common electrode layer 17 is disposed on the side of the counter substrate 14 close to the liquid crystal layer 15, it is beneficial to fabricate each film layer on the counter substrate 14.

[0080] In some examples, the carrier substrate 11, the counter substrate 14, and the cover plate 24 can be made of materials such as glass, acrylic, and polycarbonate. The pixel electrode layer, the common electrode layer 17, the first electrode layer 21, and the second electrode layer 23 can be made of materials such as indium tin oxide or indium zinc oxide.

[0081] Some embodiments of the present application further provide a display device, such as Figure 9 As shown, the display device 200 includes the display module 100 described in any of the above embodiments.

[0082] Since it includes the display module 100, the display device 200 has the technical effects possessed by the above display module 100, which will not be elaborated here.

[0083] In some examples, the display device 200 further includes a frame 201 for mounting the display module 100 to fix and protect the display module 100.

[0084] Figure 9 Only taking a mobile phone as an example, the display device 200 is described. It can be understood that the display device 200 provided by the embodiments of the present application can also be other devices with a display function such as a computer, a television, and a vehicle-mounted display device. The embodiments of the present application do not limit this.
