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 panel and an electronic device are provided. The display panel includes a first substrate and a second substrate disposed opposite to each other, and a sealant between the first substrate and the second substrate. The light-shielding layer is located on a side of the second substrate facing toward the first substrate, and grooves are defined at positions where the sealant is. The grooves penetrate the light-shielding layer to block a path of water vapor entering the display panel through the light-shielding layer, thereby easing a problem of the intrusion path of the water vapor in current liquid crystal display panels.
