Abstract: A shift register, a gate driver circuit, and a display device are disclosed. In the shift register, when a pull-up node is at a low level, a third signal control end controls a conduction of a first noise reduction module and provides the pull-up node with a low-level signal of a first power supply end, so as to pull down a signal of the pull-up node to reduce noise. Therefore, an issue of noise interference on an output end of a gate driving signal is solved when a clock signal provided by a clock signal end is at a high level.

Abstract: The present invention provides a viewing angle diffuser film and a display panel, including a base substrate and refractive protrusions. By setting space ratios of adjacent refractive protrusions in a first direction and a second direction, refraction directions of the viewing angle diffuser film can be controlled, and therefore light diffusion effects can be controlled. In the display panel of the present invention, the space ratios of the refractive protrusions in different directions are adjusted according to different usage scenarios to improve display brightness and reduce color shifts.

Abstract: A display device is provided. The display device includes a timing controller and a plurality of driver chips. The timing controller is configured to output display data. The driver chips include a plurality of first driver chips and a plurality of second driver chips. At least a part of the second driver chips are electrically connected to the first driver chips. Each of the first driver chips is electrically connected to the timing controller and a corresponding one of the second driver chip. Each of the first driver chips is configured to receive the display data, amplify the display data, and transmit the amplified display data to the corresponding one of the second driver chips. The loss of the display data transmitted to the second driver chips due to the long transmission lines can be reduced, thereby improving the display effect.
