Abstract

The present invention relates to a structure of a miniaturized refractive astigmatism lens and a backlight module. The structure of the miniaturized refractive astigmatism lens is an axisymmetric structure relative to the normal line of the lens center, which includes: a first refraction surface arranged on the upper surface of the lens; The second refraction surface arranged on the bottom surface of the lens; the first diffuse reflection surface arranged on the side surface of the lens; the second diffuse reflection surface arranged on the bottom surface of the lens; wherein the first diffuse reflection surface is respectively connected with the first refraction surface and the second The diffuse reflection surface is connected; the second diffuse reflection surface is also connected with the second refraction surface; this lens adopts an astigmatism structure, which can diffuse the 120° half-light intensity angle emitted by the LED into a 162° half-light intensity angle, so that The light mixing distance of the LED backlight module is further reduced, thereby reducing the thickness of the backlight module.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of liquid crystal display backlight modules, and in particular to a structure of a miniaturized refraction astigmatism lens and a backlight module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as light weight, thin body, power saving, etc., and thus has been widely used. The backlight of traditional liquid crystal display devices adopts cold cathode ray tube (CCFL). At present, LED light source has become a new type of replacement for cold cathode ray tube (CCFL) because of its advantages such as uniform distribution of illuminants, longer life, and better environmental protection. Backlight source. [0003] At present, ultra-thinning is the development trend of liquid crystal display devices. At present, the refracting backlight lens adopts a larger size and volume to realize the light scattering function, which has the ...
