Problems solved by technology

like figure 1 As shown, due to the relative position between the support member 51 and its surrounding light source 52 or the brightness difference between the support member 51 and the surrounding light sources 52, there will be obvious shadows near the support member 51, and this shadow will further cause the shadow near the backlight module support member. Distortion of the actual image

Abstract

The invention provides a backlight module which comprises a substrate, a light source and at least one polygonal supporting piece, wherein the substrate comprises a bottom surface, and the light source is arranged on the substrate. A cross section of the polygonal supporting piece comprises a first side edge, and an included angle between a projection line of a connecting line of a middle point of the first side edge and the light source on the bottom surface and a projection line of the first side edge on the bottom surface is in a range from 80 degrees to 100 degrees.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module with a support. Background technique [0002] With the rapid progress of liquid crystal display (liquid crystal display, LCD) production technology, and its advantages of lightness, lightness, power saving and no radiation, the liquid crystal display is widely used in tablet computers, notebook computers, digital cameras, digital cameras, etc. VCRs, mobile phones, computer screens and LCD TVs and other electronic products. However, since the liquid crystal display panel in the liquid crystal display is a non-self-illuminating display panel, it needs the light source provided by the backlight module to produce the display function. [0003] Large-sized liquid crystal display panels usually need to install several support members between the backlight module and the liquid crystal panel or between the backlight module and an optical plate such as a diffuser plate to maintai...
