Abstract

The invention discloses a viewing angle diffusion diaphragm and a display panel. The viewing angle diffusion diaphragm comprises a substrate and refraction protrusions arranged on the surface of the substrate. Each refraction protrusion comprises a first side face away from the center of the substrate, and each first side face comprises a first curved surface. When a light beam emitted by a lightsource of the display panel is emitted into the refraction protrusions, the propagation directions of emergent light of the parallel light rays refracted by different parts on the curved surfaces aredifferent; therefore, the viewing angle diffusion diaphragm has a plurality of modulation angles for one beam of incident light, the modulation capability of the viewing angle diffusion diaphragm is enhanced, and the light shape of emergent light modulated by the viewing angle diffusion diaphragm is more dispersed when the viewing angle diffusion diaphragm is applied to a display panel with more concentrated light shape emitted by the light source, so that the image quality effect of a large-viewing-angle display image is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a viewing angle diffusion film and a display panel. Background technique [0002] With the improvement of the resolution of the display panel, the performance of the brightness of the display panel at a large viewing angle becomes worse and worse. In order to solve this problem, the industry usually adds a viewing angle diffusion film to the display panel, and uses the viewing angle diffusion film to modulate the light of the front viewing angle of the display panel to a large viewing angle, thereby increasing the display brightness of the large viewing angle. [0003] However, the existing viewing angle diffuser film generally only has one modulation angle for a beam of incident light, resulting in a limited ability to modulate the incident light wave. The diffusion effect is poor, affecting customer experience. Contents of the invention [0004] In the first aspe...
