Abstract

A light convergence structure includes light convergence portions. Each light convergence portion includes a frustum structure and a plano-convex structure. The frustum structure includes a first end surface and an opposite second end surface. An area of the first end surface is less than an area of the second end surface. The plano-convex structure is on the second end surface of the frustum structure. The plano-convex structure includes a flat surface and an opposite convex spherical surface. The flat surface is in contact with the second end surface. An area of the flat surface is equal to the area of the second end surface. The first end surfaces of the light convergence portions are coplanar and together define a light incident surface of the light convergence structure.

Description

technical field [0001] The invention relates to the technical field of liquid crystal product production, in particular to a light converging structure and a backlight module. Background technique [0002] Smart display includes features such as anti-peeping, HDR (High-Dynamic Range, high-dynamic range imaging), low power consumption, and extreme module structure. It is one of the technological trends in the development of the display industry today. However, the technical bottleneck of directional optics in smart display technology lies in the collimation of light beams. Existing collimation solutions include thin-film digging, adding absorption gratings, etc. Although these solutions can achieve a certain near-collimation effect, the brightness is reduced by more than 30%. , the thickness of the module will also increase, which not only does not meet the design requirements of low power consumption, but also does not meet the development trend of extreme module structure. ...
