Description

Diffusion film for improving picture display effect

Technical Field

The utility model relates to a diffusion barrier technical field specifically is a diffusion barrier for improving picture display effect.

Background

With the advent of the digital age, Liquid Crystal Display (LCD) technology has become one of the most popular display technologies in use today and will occupy the dominant technical position in the field of flat panel displays for some time. The liquid crystal display generally comprises a liquid crystal panel and a backlight module, wherein the backlight module mainly comprises a light source, a diffusion film, a light guide plate, a diffusion film, a brightness enhancement film, an outer frame and other components. The liquid crystal molecules do not emit light themselves, and the image or character displayed by the liquid crystal molecules is the result of modulating light emitted by a backlight source, which is an important component determining the display performance of the liquid crystal, and the brightness of the backlight source directly determines the display brightness of the surface of the LCD. The diffusion film is one of the most important optical films in a liquid crystal display, and plays important roles in improving optical action rate and saving power consumption. However, the backlight brightness of the conventional diffusion film is not uniform, which results in a reduction of the display effect of the image.
