Abstract: A display module is provided. The display module includes a cover plate and a reflection layer. A touch light source is disposed in an edge region of the display module. A first grating is disposed on a side of the cover plate facing toward the touch light source. The first grating is obliquely disposed to the cover plate. After light emitted from the touch light source passes through the first grating, the light enters into the cover plate and is total reflection. Obtaining information of a to-be-recognized terminal from an entire surface of the display module can be realized after the total reflection is destroyed when the to-be-recognized terminal touches a surface of the cover plate.

Abstract: An anti-peeping film and a display device are provided. The anti-peeping film includes multiple anti-peeping layers. Each anti-peeping layer includes light-blocking portions and light-transmissive portions. The light-blocking portions are arranged in parallel. Each light-transmissive portion is connected between adjacent two light-blocking portions. The anti-peeping film includes multiple anti-peeping layers, each anti-peeping layer includes multiple equidistant light-blocking portions and multiple light-transmissive portions, a ratio of a width of the light-blocking portion in an arrangement direction to a width of the light-transmissive portion in the arrangement direction ranges from 0.045:1 to 0.088:1. Accordingly, a proportion of the area occupied by the light-transmissive portions is increased, leading to an enhancement in the light transmittance of the anti-peeping film. The presence of the light-blocking portions guarantees the light-blocking effect of the anti-peeping film. Therefore, both anti-peeping effectiveness and high light transmittance can be achieved at the same time.

Abstract: A display device includes: a backlight module including a backlight source and a light profile adjustment film; and an optical machine module disposed on a side of the light profile adjustment film away from the backlight source. The light profile adjustment film includes an optical adjustment microstructure, and included angles between main optical axes and normal lines of light emitted from the backlight source after passing through the light profile adjustment film are centrally symmetrical with respect to a center of the light profile adjustment film. The included angle is increased or remains unchanged from the center of the light profile adjustment film to an edge of the light profile adjustment film.

Abstract: A display panel and a display device are provided. A light-controlling component configured to adjust a signal transmitter is disposed on a light-emitting surface of the signal transmitter of the display panel, thereby allowing modulated light, emitted from the signal transmitter disposed at a predetermined included angle with respect to a bottom surface of a cover plate, to be totally reflected between a top surface and the bottom surface of the cover plate. Total reflection is interrupted at a position where a user's finger touches. Light is received and recognized by a plurality of light sensors on a sensor array after entering the display panel, thereby realizing under-display fingerprint recognition in a large area.
