Problems solved by technology

[0003] In the related art, the anti-peeping film is arranged on the light-emitting side of the backlight module in the display device. The outgoing polarized light of the backlight module first passes through the anti-peeping film and then enters the lower polarizer of the display panel. There is a space between them, the polarized light emitted by the backlight module will first enter the space between the privacy film and the lower polarizer when it passes through the privacy film, and because the refractive index of the privacy film does not match the refractive index of the air , the polarized light exiting the anti-peeping film will produce refraction and dispersion when entering the air in the above-mentioned interval space, resulting in the reduction of the polarized light component perpendicular to the absorption axis of the lower polarizer, and producing a polarized light parallel to the absorption axis of the lower polarizer polarized light component, and only the polarized light component perpendicular to the absorption axis of the lower polarizing plate can continue to propagate through the lower polarizing plate, which leads to a decrease in the transmittance of the outgoing polarized light of the backlight module on the lower polarizing plate, and the display brightness of the display panel decreases with the weakening

[0044] The embodiment of this application proposes a display component, such as figure 1 As shown, the display assembly includes a privacy film 2 and a display panel 1 having a color filter substrate 11 and an array substrate 12. The privacy film 2 includes a first substrate 21 and a second substrate 22 arranged at intervals. The first substrate 21 is provided with The first electrode layer 23, the second substrate 22 is provided with the second electrode layer 24, the polymer 25 and the nematic liquid crystal 26 are filled between the first electrode layer 23 and the second electrode layer 24; the second substrate 22 is arranged on the array The substrate 12 faces away from the side of the color filter substrate 11, and is located between the array substrate 12 and the first substrate 21; the display component also includes a polarizing layer 3, and the polarizing layer 3 is arranged on a side of the first substrate 21 facing away from the second substrate 22. side, and is us...

Embodiment 2

[0057] The present application also proposes a display device, such as Image 6 As shown, the display device includes the display assembly and the backlight module 5 in the above-mentioned embodiments, the display assembly is arranged on the light-emitting side of the backlight module 5, and the polarizing layer 3 of the display assembly is located on the anti-peeping side of the backlight module 5 and the display assembly. Between membrane 2.

[0058] In this embodiment, the backlight module 5 is used to provide backlight for the display panel 1. The light output from the light output side of the backlight module 5 passes through the polarizing layer 3 and the anti-peeping film 2 in sequence and then enters the display panel 1. The light output from the backlight module 5 It can be polarized light. For example, a light source and a reflective brightness enhancement film are arranged in the backlight module 5, and the light emitted by the light source becomes polarized light w...

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to a display component and a display device. Background technique [0002] In the PDLC (polymer dispersed liquid crystal) framework of display technology, the mixture of organic polymer and liquid crystal is filled between two conductive electrode layers, and the gap between the two conductive electrodes is activated by energizing the two conductive electrodes. An electric field that can drive the deflection of liquid crystal molecules is generated between them, thereby adjusting the light-emitting viewing angle of the entire PDLC structure. The PDLC structure is often used in the production of anti-peeping film, and applied in the display device, so that the display device has the anti-peeping function. [0003] In the related art, the anti-peeping film is arranged on the light-emitting side of the backlight module in the display device. The outgoing polar...
