Abstract

The invention provides a diffusion barrier, a backlight module and a display device. The diffusion barrier comprises a substrate layer, a scratch proof layer and a diffusion layer, wherein the scratch proof layer is arranged on one surface of the substrate layer; the raw material of the scratch proof layer includes flexible particles; the flexible particles are protruded from the surface, being far away from the substrate layer, of the scratch proof layer; the diffusion layer is arranged on the surface, being far away from the scratch proof layer, of the substrate layer; and the raw material of the diffusion layer includes diffusion particles. The diffusion barrier includes the scratch proof layer; the raw material of the scratch proof layer includes flexible particles; and when the diffusion barrier is applied to the backlight module, the flexible particles in the scratch proof layer can buffer the external force and avoid scratching a light guide plate.

Description

Diffusion film, backlight module and display device technical field The present application relates to the display field, in particular, to a diffusion film, a backlight module and a display device. Background technique A liquid crystal display (LCD, Liquid Crystal Display) has become the most common display technology in today's society. The LCD is a non-luminescent display device, which needs a backlight module to achieve the display function. The main components of the backlight module include: light source, light guide plate and various optical films. According to the position of the light source distribution, it can be divided into two types: side-light type and direct-light type. The edge-lit backlight module can realize ultra-thin display to the greatest extent, and has become the main form of the backlight module at present. The light guide plate is one of the indispensable components of the edge-lit backlight module. In traditional light guide plates, diffuse...
