In combination with the film layer in fig. 2, the light filtering units are arranged in an array on the substrate. Specifically, the first sub-filter unit 21 is set as a blue color resistor and correspondingly set in a blue light-emitting pixel region, the second sub-filter unit 22 is set as a green color resistor and correspondingly set in a green light-emitting pixel region, the third sub-filter unit 23 is set as a red color resistor and correspondingly set in a red light-emitting pixel region, and the second filter unit 24 is a white color resistor and correspondingly set in a white light-emitting pixel region. Preferably, the first sub-filter unit 21, the second sub-filter unit 22, and the third sub-filter unit 23 may also be arranged in other manners, and color resistances with different colors are set in corresponding light-emitting pixel regions, which is not described in detail herein.
Referring to fig. 2 in detail, in the embodiment of the present application, the second filter unit 24 further includes a light blocking wall 103, wherein the light blocking wall 103 is disposed along a thickness direction of the color filter layer 105, and divides the second filter unit 24 into a light transmitting region 242 and a non-light transmitting region 241 in the thickness direction. Specifically, the light-shielding wall 103 corresponds to the non-light-transmitting region 241, and the region where the light-shielding wall 103 is not disposed is a light-transmitting region, so that light can directly transmit through the light-transmitting region for display.
Further, the height of the light-shielding wall 103 is the same as the thickness of the corresponding color filter layer 105, and in order to ensure the anti-peeping effect of the light-shielding wall, when the light-shielding wall 103 is disposed, the light-shielding wall is disposed at least at the central region of the second filter unit 24 and extends from the central region of the second filter unit 24 to two side edges.

Specifically, after the light emitted from the light emitting unit 1001 reaches the color filter layer 105, the light can be emitted from any direction in the first sub-filter unit 21, the second sub-filter unit 22, and the third sub-filter unit 23, and in the second filter unit 24, due to the light-shielding wall 103, the light can only pass through the light-transmitting region 242, but the light in the non-light-transmitting region 241 cannot pass through, so as to control the light-emitting viewing angle of the display panel, and effectively achieve the purpose of peep prevention.
As shown in fig. 4, fig. 4 is a schematic structural diagram of another color filter layer provided in this embodiment of the application. In the embodiment of the present application, in the second optical filter unit 24, a filling layer 1031 may be further disposed in the light-transmitting region, and the filling material may be a white high-transmittance material, such as a high-transmittance optical glue or a resin material. And when the filling layer 1031 is provided, the light scattering particles 1033 may be further provided in the filling layer 1031.
Specifically, the light scattering particles 1033 are uniformly distributed in the light transmission region 242, and in order to ensure good uniformity, the particle diameters of the light scattering particles 1033 may be set to be the same or may be set according to the size of each light transmission region 242. When the light is transmitted to the light scattering particles 1033, the light scattering particles 1033 can act on the light again, so that the scattering angle of the light is further increased, the display effect of the display panel is effectively improved, and the light at a specific angle can be scattered to the shading retaining wall, so that the peep-proof effect of the shading retaining wall is improved.
Preferably, in the second filter unit 24, the light-shielding walls 103 may be disposed in a plurality, and a plurality of light-shielding walls 103 may be disposed at intervals to realize fine adjustment of the peep-proof angle, and the width of the light-shielding walls is smaller than that of the second filter unit.
Meanwhile, the side surfaces of the light-shielding walls 103 may be set as vertical surfaces, or a certain inclination angle may be formed between the corresponding side surface and the bottom surface of the color filter layer. Preferably, the angle of the inclination angle is set to 60 ° to 90 °. When the side of the light-shielding retaining wall 103 is set as an inclined side, the inclined directions of the left side and the right side can be inclined towards one direction, and the inclined angles can be the same or different, so that the light rays in different directions can be acted, and the peeping-proof effect of the display panel is improved.
As shown in fig. 5, fig. 5 is a schematic view illustrating the light effect of the display panel for preventing peeping in the embodiment of the present application. When the light emitting unit 1001 in the backlight module emits light, the light passes through the liquid crystal layer 102 thereon, and at this time, the liquid crystal 1022 in the liquid crystal layer 102 is deflected under the driving of the thin film transistor in the corresponding pixel region, for example, the corresponding liquid crystals in the regions of the first sub-filter unit 21, the second sub-filter unit 22, the third sub-filter unit 23, and the second sub-filter unit 24 are respectively controlled to deflect the light, and the deflected light enters the color filter layer 105 again.
Preferably, the peep-proof effect is not achieved when the display panel is fully displayed. The liquid crystal 1022 in the area corresponding to the second sub-filter unit 24 and the corresponding light emitting unit 1001 in the area are adjusted. When the corresponding light emitting unit 1001 in the second sub-filtering unit 24 does not emit light, no light can conveniently pass through the light emitting unit, and the light reaching the second sub-filtering unit 24 is less, while in other filtering units, the light can normally pass through. Thus, the second filter unit 24 cannot form a strong white light and cannot interfere with other regions, so that the display panel can be normally viewed at different angles.
When the corresponding light emitting unit 1001 in the second filter unit 24 normally emits light, the light emitting unit 1001 emits light, and the light reaches the color filter layer 105 through the deflection of the liquid crystal layer, at this time, because the light blocking wall 103 is arranged in the second filter unit 24, and the second filter unit 24 is set as a white color resistor, the light forms stronger white light in the white color resistor, meanwhile, because the light scattering particles are also arranged in the white color resistor in the embodiment of the present application, the light scattering particles can further improve the effect of the light, and further improve the intensity of the white light, and in other filter units, the light is normally displayed, and the light intensity in the white color resistor at the edge is larger, so that when observing from the side view direction of the display panel, the picture on the side view angle is whitish and invisible by the stronger white light, and the observer cannot observe the content in the display panel, thereby realizing the peep-proof effect of the display panel.

When an observer observes from the side face, the display panel comprehensively shows that the side view picture is whitish and invisible, and the front view picture is slightly influenced or not influenced, so that the peeping prevention effect of the display panel is realized, and the switchable peeping prevention performance is achieved.
Further, in combination with the film structure in fig. 1, in the embodiment of the present application, when the first polarizer 101 and the second polarizer 106 are disposed, absorption axes of the polarizers corresponding to the first polarizer 101 and the second polarizer 106 are orthogonal to each other, so as to achieve better polarization and display effects.
