Support pillar of LED (light emitting diode) backlight module

Abstract

The invention discloses a support pillar of an LED (light emitting diode) backlight module, wherein the support pillar is arranged between a backplane and an optical diaphragm of the LED backlight module; the bottom of the support pillar is fixed on the backplane; a plurality of LED light sources are arranged on the backplane and are distributed like a centre symmetry figure; the support pillar is arranged in the centre of the centre symmetry figure; the support pillar is of a prism structure or prismatic table structure; and the LED light sources are respectively arranged on mid-perpendiculars of bottom borders of the sides of the support pillar. Due to the fact that the LED light sources of the LED backlight module are distributed like the centre symmetry figure, the support pillar is made of a transparent material and arranged in the centre of the centre symmetry figure, and the support pillar is of the prism structure or prismatic table structure, a shadow formed in the LED backlight module by the support pillar is eliminated with lower cost.

Description

technical field [0001] The invention relates to a support column of a direct-type backlight module in liquid crystal display technology, in particular to a support column of an LED backlight module. Background technique [0002] Liquid crystal display technology has always been used in portable electronic products such as notebook computers, mobile phones, digital cameras, camcorders, and PDAs. In addition to these smaller portable products, the manufacturing technology of large-size liquid crystal panels has also matured recently. For example, desktop LCD monitors have replaced CRT monitors, and LCD TVs are also replacing traditional TVs with their advantages of light weight and clear pictures. The liquid crystal panel is the most critical display element in this field. However, it does not emit light itself, and needs a backlight source to display images. Many backlight technologies exist today, and in large-size liquid crystal display products above 20 inches, direct-li...
