Abstract

It is an aphototropism element, which comprises backboard, diffusion plate, supporting part and multiple tubes. The diffusion plate is set on the backboard and the supporting part is set between the backboard and the diffusion plate. The supporting part comprises a socket and one fixing part, wherein; the fixing part has one supporting part contacted with the diffusion plate to avoid the bending of the diffusion plate. The multiple tubes are set between the socket and fixing part as the light source of aphototropism element.

Description

technical field [0001] The present invention relates to a backlight assembly, in particular to a backlight assembly with a spacer to maintain a predetermined distance between a diffuser plate and a light source. Background technique [0002] Generally, a liquid crystal display uses a backlight assembly as a light source, and the backlight assembly can be divided into two types: side-light type and direct-light type, depending on the location of the light source. Such as figure 1 As shown, the direct type backlight assembly 10 includes a reflector 11 , a diffusion plate 12 , a plurality of support columns 13 and a plurality of lamp tubes 14 . The reflector 11 is located at the bottom of the backlight assembly 10, the diffusion plate 12 is arranged on the reflector 11, the lamp tube 14 is arranged between the reflector 11 and the diffuser plate 12, the reflector 11 can reflect the light of the lamp tube 14 out of the backlight assembly 10 , as the light source for the planar...
