Each first color resistance portion is configured to absorb one or both of a first color light, a second color light, and a third color light, and allow the remaining color light to pass through. Among them, the first color light, the second color light, and the third color light can be mixed to form white light.

Terms such as "a plurality of" and similar words mean two or more, unless otherwise clearly defined.

[0029] "A and / or B" includes the following three combinations: only A, only B, and the combination of A and B.

[0030] The use of "for" or "suitable for" in the present application means open and inclusive language, which does not exclude devices suitable for or configured to perform additional tasks or steps.

[0031] In the present application, the word "example" is used to mean "serving as an example, illustration or explanation". Any embodiment described as an "example" in the present application is not necessarily construed as being more preferred or having more advantages than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application.

[0032] 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.

[0033] Some embodiments of the present application provide a display device, such as Figure 1 As shown, the display device 1000 can be any device that displays whether it is moving (for example, video) or stationary (for example, a still image), and whether it is text or an image.

[0034] Exemplarily, the display device 1000 can be a television, a laptop computer, a tablet computer, a mobile phone, a personal digital assistant (Personal Digital Assistant; abbreviated as PDA), a navigator, an in-vehicle display, a flight display, a wearable device, a virtual reality (Virtual Reality; abbreviated as VR) device, or any other product or component with a display function.

[0035] In some examples, please continue to refer to Figure 1, the display device 1000 includes a display panel 200 and a dimming film 100, and the dimming film 100 is disposed on the light-emitting side of the display panel 200.

[0036] In the related art, when the image displayed on the display panel is viewed from a side view angle, the hue will tend to one or more colors, resulting in an obvious color shift phenomenon in the display device to which the display panel is applied.

[0037] In the embodiment of the present application, since the dimming film 100 is disposed on the light-emitting side of the display panel 200, for the light of the display panel 200 viewed from a side view angle, the dimming film 100 can absorb light of a specific color and allow light of another part of the color to pass through, thereby effectively improving the problem of obvious color shift of the display device 1000 viewed from a side view angle.

[0038] The specific structure of the dimming film 100 will be described in detail in the following embodiments.

[0039] As Figure 2 shown, the dimming film 100 includes a substrate 10 and a color resistance layer 20 located on one side of the substrate 10. The color resistance layer 20 includes a plurality of first color resistance portions 21 spaced apart from each other, and a light-transmitting gap is provided between adjacent first color resistance portions 21. Each first color resistance portion 21 is configured to absorb one or both of the first color light, the second color light, and the third color light, and allow the remaining color light to pass through. It should be noted that the remaining color light refers to the light other than the light absorbed by the first color resistance portion among the first color light, the second color light, and the third color light. In addition, in the description herein, the absorption of a certain color light by the color resistance portion means that the color light is absorbed by the color resistance portion when passing through the color resistance portion.

[0040] The first color resistance portion 21 is configured to absorb one or both of the first color light, the second color light, and the third color light, and allow the remaining color light to pass through, which can be in the following situations. For example, when the first color resistance portion 21 is configured to absorb the first color light, it allows the second color light and the third color light to pass through; when the first color resistance portion 21 is configured to absorb the second color light, it allows the first color light and the third color light to pass through; when the first color resistance portion 21 is configured to absorb the third color light, it allows the first color light and the second color light to pass through. Another example is that when the first color resistance portion 21 is configured to absorb the first color light and the second color light, it allows the third color light to pass through; when the first color resistance portion 21 is configured to absorb the first color light and the third color light, it allows the second color light to pass through; when the first color resistance portion 21 is configured to absorb the second color light and the third color light, it allows the first color light to pass through.

[0041] Among them, the first color light, the second color light, and the third color light can be mixed to form white light. As an example, the first color light can be one of red light, green light, and blue light, the second color light is one of the remaining two of red light, green light, and blue light, and the third color light is the last remaining one of red light, green light, and blue light. Of course, in some other examples, the first color light, the second color light, and the third color light can be any combination of cyan light, magenta light, and yellow light.

[0042] In the embodiments of the present application, please continue to refer to Figure 2 , since a light-transmitting gap K is provided between adjacent first color-resist portions 21, the normal emission of light at the front view angle A can be ensured in this way, so as to ensure the display brightness of the display device 1000 at the front view angle A. In addition, since the first color-resist portion 21 can absorb one or both of the first color light, the second color light, and the third color light and allow the remaining color light to pass through, the color of the light absorbed by the first color-resist portion 21 can be targeted controlled according to the actual color deviation of the display panel 200, and the color of the light passing through the first color-resist portion 21 can be controlled, thereby effectively alleviating the phenomenon of obvious color deviation of the display device 1000 at the side view angle B. Moreover, the dimming film 100 provided by the embodiments of the present application is convenient to replace and has a low manufacturing cost, so that the manufacturing and use costs of the display device 1000 can be effectively reduced.

[0043] As an example, please continue to refer to Figure 2 , when the display panel 200 has a color deviation of the first color at the side view angle, the first color-resist portion 21 is used to absorb the first color light 01 and allow the second color light 02 and the third color light 03 to pass through. In this way, on the one hand, the amount of the first color light 01 at the side view angle B is effectively reduced, thereby alleviating the problem of obvious color deviation of the display device 1000 at the side view angle; on the other hand, the amounts of the second color light 02 and the third color light 03 at the side view angle B are effectively guaranteed, so that the color of the display device 1000 at the side view angle B is consistent with the color at the front view angle A, and further effectively improves the problem of color deviation of the display device 1000 at the side view angle B.

[0044] In another example, the display panel 200 exhibits color shifts of a first color and a second color in a side view. At this time, the first color filter portion 21 is configured to absorb the first color light and the second color light, and allow the third color light to pass through. On the one hand, this effectively reduces the amounts of the first color light and the second color light in the side view, thereby alleviating the problem of obvious color shift of the display device 1000 in the side view. On the other hand, it also effectively ensures the amount of the third color light in the side view, so that the color of the display device 1000 in the side view is consistent with the color in the front view, and further effectively improves the problem of color shift of the display device 1000 in the side view.

[0045] In some embodiments, the display panel 200 is a vertically aligned liquid crystal display panel. Among them, the vertically aligned liquid crystal display panel is a VA (Vertical Alignment) type liquid crystal display panel. The VA type liquid crystal display panel includes an array substrate and a color filter substrate disposed opposite to each other, and a liquid crystal layer located between the array substrate and the color filter substrate. Among them, pixel electrodes are provided on the array substrate, and common electrodes are provided on the color filter substrate. When no voltage is applied between the pixel electrode and the common electrode, the liquid crystal molecules in the liquid crystal layer are arranged perpendicular to the array substrate. At this time, the light from the backlight is blocked by the liquid crystal layer, and the display panel presents black. After a voltage is applied between the pixel electrode and the common electrode, the liquid crystal molecules gradually rotate in the horizontal direction, so that the light from the backlight can pass through the liquid crystal layer. According to the different magnitudes of the applied voltage, the intensity of the light passing through the display panel is also different, so that the display panel presents a picture with different colors and brightnesses.

[0046] In some examples, the first color light is red light, the second color light is green light, and the third color light is blue light. The first color filter portion 21 is configured to absorb red light and allow green light and blue light to pass through.

[0047] It should be noted that for a VA type liquid crystal display panel, in its side view, since red light, green light, and blue light have different wavelengths, the refraction angles of these lights are different when passing through the display panel (such as the liquid crystal layer), and thus there will be an obvious color shift problem when viewing the display panel from the side view. Among red light, green light, and blue light, red light has the longest wavelength, so a red color shift phenomenon will occur in the side view.

[0048] In the present application, since the first color filter portion 21 is configured to absorb red light and allow green light and blue light to pass through. In this way, the problem of red color shift of the VA type liquid crystal display panel in the side view can be effectively improved.

[0049] In some examples, the first color filter portion 21 may adopt a cyan color filter.

[0050] In some embodiments, such as Figure 3 shown, the display panel 200 is a self-emitting display panel. The display panel 200 includes a first light-emitting chip 201 for emitting first-color light, a second light-emitting chip 202 for emitting second-color light, and a third light-emitting chip 203 for emitting third-color light. The first light-emitting angle M1 of the first light-emitting chip 201 is smaller than the second light-emitting angle M2 of the second light-emitting chip 202 and the third light-emitting angle M3 of the third light-emitting chip 203. The first-color light is red light, the second-color light is green light, and the third-color light is blue light. The first color-resist portion 21 is used to absorb green light and blue light and allow red light to pass through.

[0051] Since the first light-emitting angle M1 of the first light-emitting chip 201 is relatively small, and the second light-emitting angle M2 of the second light-emitting chip 202 and the third light-emitting angle M3 of the third light-emitting chip 203 are relatively large, this causes the green light and the blue light to be easily mixed and form a cyan color deviation phenomenon when viewing the self-emitting display panel from a side view angle.

[0052] In this embodiment, by absorbing the green light and the blue light through the first color-resist portion 21 and allowing the red light to pass through, the cyan color deviation problem of the self-emitting display panel from a side view angle can be effectively improved.

[0053] In some examples, the light-emitting layer of the first light-emitting chip 201 can be made of gallium arsenide material, and the light-emitting layers of the second light-emitting chip 202 and the third light-emitting chip 203 can be made of gallium nitride material respectively.

[0054] In some embodiments, the display panel includes a plurality of liquid crystal display panels and a self-emitting display panel located between two adjacent liquid crystal display panels. That is to say, the display panel is a tiled display panel.

[0055] Since the color deviation colors of the liquid crystal display panel and the self-emitting display panel are different, the seam of the display panel as a whole is obvious from a side view angle, which further affects the final tiling effect. In the embodiments of the present application, since a dimming film 100 is provided on the light-emitting side of the display panel as a whole, the color deviation problem of the display panel as a whole from a side view angle can be alleviated through the dimming film 100, and further the display effect of the display device 1000 can be improved.

[0056] In some embodiments, such as Figure 4As shown, the first color filter portion 21 is configured to absorb the first color light and the third color light and allow the second color light to pass through. The dimming film 100 further includes a substrate 30 and an auxiliary dimming layer 40 that are sequentially disposed on a side of the color filter layer 20 away from the substrate 10. The auxiliary dimming layer 40 includes a plurality of color filter elements 41 that are disposed on the substrate 30 and spaced apart from each other. Among them, the substrate 30 can be in direct contact with the color filter layer 20. In addition, the material of the substrate 30 can be the same as or different from the material of the substrate 10, and the embodiments of the present application do not limit this.

[0057] Each color filter element 41 is configured to absorb one of the first color light and the third color light, and the second color light, and allow the other of the first color light and the third color light to pass through. That is to say, the color of the light allowed to pass through by the color filter element 41 is different from the color of the light allowed to pass through by the first color filter portion 21. As an example, the color filter element 41 is configured to absorb the first color light and the second color light and allow the third color light to pass through.

[0058] In this case, the color filter layer 20 and the auxiliary dimming layer 40 can each regulate light of different colors, thereby effectively improving the phenomenon of color deviation of the display device 1000 at a side view angle. As Figure 5 shown, when color deviations of different colors appear at different positions of the display panel 200, for the second color light, it can sequentially pass through the first color filter portion 21, the substrate 30, and the light-transmitting gap between two adjacent color filter elements 41 and exit, thereby alleviating the color deviation phenomenon caused by the lack of the second color light in a large viewing angle range; in addition, the third color light can sequentially pass through the light-transmitting gap K between two adjacent first color filter portions 21, the substrate 30, and the color filter element 41 and exit, thereby alleviating the color deviation phenomenon caused by the lack of the third color light in a relatively small viewing angle range.

[0059] In some examples, the substrate 30 is a thickness-adjustable plate. In this way, by adjusting the thickness of the substrate 30, the distance between the color filter layer 20 and the auxiliary dimming layer 40 can be changed, and then this distance can be used to further adjust the emission of light of different colors from the display panel 200 to avoid the problem of color deviation of the display device 1000 at a side view angle.

[0060] In some examples, the thicknesses of the color-resist layer 20 and the auxiliary dimming layer 40 are different. That is, along the thickness direction Z of the dimming film 100, the height of the color-resist member 41 is different from the height of the first color-resist portion 21. In this case, the phenomenon of color shift of the display device 1000 at a side viewing angle can be further improved by adjusting the thickness difference between the color-resist layer 20 and the auxiliary dimming layer 40. For example, the thickness of the color-resist layer 20 is less than the thickness of the auxiliary dimming layer 40. With such a setting, the modulation effect of the color-resist layer 20 on the second color light is relatively weak, while the modulation effect of the auxiliary dimming layer 40 on the third color light is relatively strong. In this way, the phenomenon of color shift caused by the lack of the third color light in a relatively small viewing angle range of the display panel 200 can be effectively improved, which is stronger than the phenomenon of color shift caused by the lack of the second color light in a relatively large viewing angle range.

[0061] In some embodiments, as Figure 4 and Figure 5 shown, each color-resist member 41 is disposed opposite to a first color-resist portion 21. As an example, the orthographic projection of each color-resist member 41 on the substrate 10 coincides with the orthographic projection of the first color-resist portion 21 opposite to the color-resist member 41 on the substrate 10.

[0062] By disposing the color-resist member 41 opposite to the first color-resist portion 21, the light emission of the display panel 200 at a front viewing angle can be effectively guaranteed, thereby ensuring the display brightness of the display device 1000 at a front viewing angle.

[0063] In some examples, the display panel 200 has a plurality of sub-pixels, and the light emitted by each sub-pixel exits through the light-transmitting gap K between adjacent first color-resist portions 21. As an example, the light-emitting center of each sub-pixel coincides with the center of a corresponding light-transmitting gap K in the thickness direction of the display device 1000. In this way, the display device 1000 can have a good light-emitting effect.

[0064] In some embodiments, as Figure 6 shown, the first color-resist portion 21 is configured to absorb the second color light and the third color light and allow the first color light to pass through. The color-resist layer 20 further includes a plurality of second color-resist portions 22 spaced apart from each other, and the second color-resist portions 22 are configured to absorb the first color light and the third color light and allow the second color light to pass through. Among them, the plurality of second color-resist portions 22 and the plurality of first color-resist portions 21 are arranged in an interleaved manner. For example, the plurality of second color-resist portions 22 and the plurality of first color-resist portions 21 are arranged in a row along the first direction X to form multiple rows of color-resist portions, where the first color-resist portions 21 are all located in odd rows, while the second color-resist portions 22 are located in even rows.

[0065] With such a setting, the first color-resist portion 21 and the second color-resist portion 22 can each regulate light of different colors, thereby effectively improving the phenomenon of color shift of the display device 1000 at a side viewing angle. AsFigure 7 As shown, since the first color blocking portion 21 allows the first color light to pass through, the color shift phenomenon caused by the lack of the first color light at a side viewing angle can be improved; the second color blocking portion 22 allows the second color light to pass through, so that the color shift phenomenon caused by the lack of the second color light at a side viewing angle can be improved.

[0066] In some embodiments, as Figure 6 and Figure 7 shown, along the thickness direction Z of the dimming film 100, a first dimension T1 of the second color blocking portion 22 is smaller than a second dimension T2 of the first color blocking portion 21.

[0067] With such a setting, the height difference between the first color blocking portion 21 and the second color blocking portion 22 can be used to further regulate the light of the display panel 200, thereby further improving the problem of color shift of the display device 1000 at a side viewing angle. As Figure 7 shown, since the height of the first color blocking portion 21 is relatively high, its modulation effect on the first color light is relatively strong, so that the color shift phenomenon caused by the lack of the first color light at a side viewing angle within a relatively large range can be improved; since the height of the second color blocking portion 22 is relatively low, its modulation effect on the second color light is relatively weak, so that the color shift phenomenon caused by the lack of the second color light at a side viewing angle within a relatively small range can be improved. It should be noted that the side viewing angle within a relatively large range is farther from the front viewing angle, while the side viewing angle within a relatively small range is closer to the front viewing angle.

[0068] In some embodiments, as Figure 8 shown, the first color blocking portion 21 is configured to absorb the second color light and the third color light and allow the first color light to pass through. The dimming film 100 further includes a plurality of auxiliary dimming portions 51. Each auxiliary dimming portion 51 covers a first color blocking portion 21, and the light transmittance of the auxiliary dimming portion 51 for the first color light is greater than 0 and less than 1.

[0069] With such a setting, the transmittance of the first color light can be further modulated by the auxiliary dimming portion 51, so that the color shift degree of the display panel 200 at a side viewing angle can be better matched.

[0070] In some examples, the light transmittance of the auxiliary dimming portion 51 for the first color light can be 40%, 50% or 60%, etc., and the embodiments of the present application do not limit this.

[0071] In some embodiments, as Figure 9As shown, the dimming film 100 may further include an opposed substrate 60 disposed opposite to the substrate 10, and the color resist layer 20 is located between the substrate 10 and the opposed substrate 60. The opposed substrate 60 and the substrate 10 can protect the color resist layer 20 to a certain extent, thereby facilitating the handling of the dimming film 100. As an example, the opposed substrate 60 and the substrate 10 can be made of the same material. For example, both can be made of glass.

[0072] In some examples, an adhesive layer is provided on the side of the substrate 10 facing away from the color resist layer 20. The adhesive layer can be used to bond the dimming film 100 to the display panel 200, so that the dimming film 100 continuously and stably regulates the color shift phenomenon of the display panel 200 at a side viewing angle.

[0073] In some examples, the dimming film 100 further includes a surface treatment layer 70 located on the side of the opposed substrate 60 away from the color resist layer 20. The surface treatment layer 70 can improve the performance of the dimming film 100. For example, the surface treatment layer 70 can be a wear-resistant layer to improve the wear resistance of the dimming film 100. Again, for example, the surface treatment layer 70 can be an anti-oil stain layer to reduce the problem of oil stain contamination during the use of the dimming film 100, thereby reducing the maintenance requirements of the dimming film 100.

[0074] In some embodiments, as Figure 10 shown, a plurality of first color resist portions 21 are arranged at intervals along the first direction X. The color resist layer 20 further includes a plurality of third color resist portions 23 spaced apart from each other along the second direction Y. The color of the light allowed to pass through each third color resist portion 23 is the same as the color of the light allowed to pass through the first color resist portion 21. For example, the material of the third color resist portion 23 is the same as the material of the first color resist portion 21. The third color resist portions 23 and the plurality of first color resist portions 21 are arranged in a grid pattern. As an example, the first direction X and the second direction Y can be perpendicular to each other.

[0075] With such an arrangement, the first color resist portion 21 can effectively improve the color shift phenomenon at the side viewing angle along the first direction X, and the third color resist portion 23 can effectively improve the color shift phenomenon at the side viewing angle along the second direction Y. In this way, the display device 1000 can have a good color shift improvement effect.
