Abstract: A display device is provided. The display device includes a display panel and a backlight module. The display panel includes sub-pixels and a light-shielding layer disposed around the sub-pixels. A reflective nano-grating is disposed on one side of the light-shielding layer near the backlight module. The backlight module provides a backlight source for the display panel, and the backlight source is converted into a polarized light in the display panel. The reflective nano-grating is used to reflect at least one part of the polarized light emitted toward the reflective nano-grating back to the backlight module for recycling.

Abstract: The present application provides a display panel and a display device. The display panel includes sub-pixels with multiple colors and upper polarizing units with various structures. The upper polarizing units with the various structures are disposed one-to-one correspondence with the sub-pixels with the multiple colors to increase transmittance of transmitted light of each color through the upper polarizing units corresponding to the sub-pixels whose color is the same as the color of the upper polarizing units.

Abstract: A display device is provided. The display device inputs a preset gray scale voltage to sub-pixels during a first time period within one frame in a second driving mode, thereby increasing a liquid crystal flipping speed within one frame, and therefore improving a response time of the display device in switching between black screen and white screen.

Abstract: The present application provides a display panel and a display device. The display panel includes a liquid crystal layer, a light adjustment layer, and a reflection layer. The liquid crystal layer includes a plurality of liquid crystal molecules. The light adjustment layer includes a plurality of light adjustment portions, and each of the light adjustment portions and a corresponding one of the liquid crystal molecules include a contact interface. The reflection layer is disposed on a side of the liquid crystal layer and the light adjustment layer away from a display side and corresponds to the light adjustment portions. An incident light is totally reflected at the contact interface or passes through the contact interface.
