Problems solved by technology

Although the distance between the light emitting diodes 10 and 12 and the active area can be enlarged, the corner dark band area 30 can be reduced, but this method will weaken the light intensity of the light emitting diodes 10 and 12 on the active area, thus requiring a larger po...

Abstract

The invention discloses a backlight module that could reduce the dark band area. Two proximate LED in the backlight module structure are set next to light guiding board. Each emitting side is inclined outward a preset angle. The outside included angle between the two emitting sides is between 90 degree and 180 degree.

Description

technical field [0001] The invention relates to a backlight module structure, in particular to a light-emitting diode (LED) backlight module structure capable of reducing dark zone areas in corners. Background technique [0002] The backlight module is one of the basic components of a liquid crystal display (Liquid Crystal Display; LCD). Since the liquid crystal itself does not emit light, the required light source needs to be provided through the backlight module. The operating principle of the backlight module is to guide the light from the backlight through the light guide plate to form a flat light source to ensure the uniformity of brightness. Commonly used backlight sources for backlight modules include cold cathode fluorescent lamps and light emitting diodes, for example. Although cold-cathode fluorescent lamps are currently the mainstream, the demand for light-emitting diodes is increasing day by day. Compared with cold-cathode fluorescent lamps, light-emitting di...
