The first embodiment is as follows:
the present application provides a display module 1, as shown in fig. 1 and fig. 2, the display module 1 includes a light modulation film 11 and a display panel 12, a color resistance layer 121 is disposed in the display panel 12, the color resistance layer 121 includes a plurality of sub-pixels 1211, the light modulation film 11 includes a first substrate 111 and a second substrate 112 disposed at an interval, the first substrate 111 is provided with an electrode layer 113, a polymer matrix 114 and nematic liquid crystals 115 dispersed in the polymer matrix 114 are disposed between the electrode layer 113 and the second substrate 112; the first substrate 111 is disposed on the light-entering side of the display panel 12 and located between the display panel 12 and the second substrate 112; the second substrate 112 is provided with a plurality of pixel units 116 on a side facing the first substrate 111, each pixel unit 116 includes a pixel electrode 1161, each sub-pixel 1211 is disposed corresponding to one pixel electrode 1161, and the pixel electrode 1161 is used for adjusting a light emitting angle of a region of the display panel 12 where the light emitting side corresponds to the sub-pixel 1211.
In this embodiment, the display panel 12 includes a color film substrate, an array substrate, and a liquid crystal filled between the array substrate and the color film substrate, the color resist layer 121 may be disposed on the color film substrate or the array substrate, the color resist layer 121 includes a plurality of sub-pixels 1211 arranged in an array, each sub-pixel 1211 is a color resist having a color, and generally, the color of each sub-pixel 1211 is one of three primary colors, i.e., red, green, and blue.
The light adjusting film 11 is used for adjusting the light emitting angle of the display panel 12, when the power is turned on, the electrode layer 113 and the pixel electrode 1161 in the light adjusting film 11 can form an electric field, the electric field will drive the nematic liquid crystal 115 dispersed in the polymer matrix 114 to deflect, so that the equivalent refractive index of the nematic liquid crystal 115 matches with the refractive index of the polymer matrix 114, thereby the incident light of the light adjusting film 11 will not be refracted when passing through the nematic liquid crystal 115 and the polymer matrix 114 and propagate along the original propagation path, so that the incident light will be incident in parallel to the light incident side of the display panel 12, and form parallel light with a narrower light emitting angle on the light emitting side of the display panel 12, so that the display panel 12 enters a narrow viewing angle display mode, i.e. a privacy mode. When the electrode layer 113 and the pixel electrode 1161 in the dimming film 11 are not powered on, an electric field is not formed between the electrode layer 113 and the pixel electrode 1161, the optical axes of the nematic liquid crystal 115 dispersed in the polymer matrix 114 are preferentially oriented, the equivalent refractive index of the nematic liquid crystal 115 is greater than the refractive index of the polymer matrix 114, so that incident light of the dimming film 11 is refracted when passing through the nematic liquid crystal 115 and the polymer matrix 114, the incident light exits the first substrate 111 of the dimming film 11 in a divergent form and enters the display panel 12, so that the light emitted from the display panel 12 is also divergent light, at this time, the display screen of the display panel 12 can be observed from the side of the display panel 12, and the display panel 12 enters a wide-viewing angle display mode, that is, a non-peep-proof mode.
In this embodiment, the pixel electrodes 1161 are disposed on the second substrate 112 side of the dimming film 11, and the pixel electrodes 1161 in the dimming film 11 and the sub-pixels 1211 in the display panel 12 are disposed correspondingly, so that the electric field intensity between the pixel electrodes 1161 and the electrode layer 113 can be controlled by controlling the on/off of the pixel electrodes 1161, thereby controlling the deflection angle of the nematic liquid crystal 115 between each pixel electrode 1161 and the electrode layer 113, controlling the light incident angle of the sub-pixel 1211 disposed corresponding to each pixel electrode 1161, and further controlling the light emergent angle of the display panel 12 corresponding to each sub-pixel 1211 on the light emergent side, so as to implement pixel-level adjustment of the light emergent from the display panel 12, which allows more precise adjustment of the light emergent from the display panel 12, and allows adjustment of the local light emergent angle of the display area of the display panel 12; for example, a part of the display area of the display panel 12 is in the narrow viewing angle display mode, and another part of the display area of the display panel 12 is in the wide viewing angle display mode, so that the display panel 12 can be applied to a scene that needs to provide different visual experiences for users located at different orientations of the display panel 12. Therefore, the display device 1 in this embodiment can achieve the light-emitting control of the display panel 12 for each sub-pixel 1211, and adjust the light-emitting angle of the local area on the light-emitting side of the display panel 12, so that the light-emitting control of the display panel 12 is more flexible, and the applicability of the display panel 12 is wider.
In an embodiment of the present application, as shown in fig. 2, the orthogonal projection of each pixel electrode 1161 on the color resist layer 121 shields a sub-pixel 1211.
In this embodiment, each pixel electrode 1161 only controls the display and expression of one sub-pixel 1211 on the color resist layer 121 correspondingly, so as to regulate and control the light emitting angle of the display area on the light emitting side of the display panel 12 corresponding to the sub-pixel 1211, thereby more finely controlling the local display effect of the display panel 12 for each sub-pixel 1211, enabling the light emitting side of the display panel 12 to correspondingly enter the narrow viewing angle display mode or the wide viewing angle display mode for each sub-pixel 1211, further enabling the local light emitting of the display area of the display panel 12 to be adjustable, improving the accuracy and flexibility of the light emitting regulation of the display panel 12, and enabling the display panel 12 to meet the display requirements in more scenes.
Optionally, the orthogonal projection of each pixel electrode 1161 on the color resist layer 121 shields the three sub-pixels 1211, and the colors of the three sub-pixels 1211 are different. The light-emitting angle of the display area of the display panel 12 corresponding to the three sub-pixels 1211 is correspondingly adjusted for each pixel electrode 1161, so that the number of the pixel electrodes 1161 can be reduced, and the distribution density, the design and processing difficulty and the material cost of the pixel electrodes 1161 are reduced. The three sub-pixels 1211 corresponding to each pixel electrode 1161 have different colors, for example, the three sub-pixels 1211 are respectively a red color resistor, a green color resistor and a blue color resistor.
In an embodiment of the present application, as shown in fig. 2, a plurality of scan lines 117 and a plurality of data lines 118 are disposed in a staggered manner on a side of the second substrate 112 facing the first substrate 111, such that two adjacent scan lines and two data lines 118 enclose to define a pixel region; each pixel unit 116 is located in a pixel region, and each pixel electrode 1161 is electrically connected to a scan line 117 and a data line 118.
In this embodiment, each pixel electrode 1161 is controlled to be turned on or off through the scan line 117 and the data line 118, so that the pixel electrode 1161 can correspondingly control the nematic liquid crystal 115 between the pixel electrode 1161 and the electrode layer 113 to deflect according to display requirements, thereby controlling the display mode of the sub-pixel 1211 in the display panel 12, and adjusting the light emitting angle of the display area corresponding to the sub-pixel 1211 on the light emitting side of the display panel 12 when the sub-pixel 1211 displays and expresses, thereby realizing the regulation and control of the light emitting of the display panel 12.
In an embodiment of the present application, as shown in fig. 2, each pixel unit 116 further includes a thin film transistor 1162; the gate of each tft 1162 is connected to a scan line 117, the source of each tft 1162 is connected to a data line 118, and the drain of each tft 1162 is connected to a pixel electrode 1161.
In this embodiment, the thin film transistor 1162 is connected to the scan line 117, the data line 118 and the pixel electrode 1161, and the thin film transistor 1162 is used as a switch for controlling the pixel electrode 1161 to turn on or off, so as to achieve automatic control of the on/off of each pixel electrode 1161, and enable the pixel electrode 1161 to correspondingly control the nematic liquid crystal 115 between the pixel electrode 1161 and the electrode layer 113 to deflect according to the display requirement, thereby controlling the display mode of the sub-pixel 1211 in the display panel 12, and adjusting the light emitting angle of the display area corresponding to the sub-pixel 1211 on the light emitting side of the display panel 12 when the sub-pixel 1211 displays and expresses, thereby achieving regulation and control of the light emitting of the display panel 12.
In an embodiment of the present application, as shown in fig. 1 and fig. 3, the display module 1 further includes a polarizing layer 13, where the polarizing layer 13 is disposed on a side of the second substrate 112 opposite to the first substrate 111, and is used for forming polarized light incident to the dimming film 11 and the display panel 12.
