Problems solved by technology

In this way, due to the limitation of processing conditions, the large aperture of the through hole 15 will make it easy for light to leak from the through hole 15, resulting in light leakage, which reduces the light source utilization rate of the cold cathode tube 13.

Abstract

The invention is a kind of drop-off back component which can select the light source utilization rate and which has heat scattering effect. The component includes a light source, a frame and a reflecting plate. The light source is set in the frame; the frame includes at least a penetrated hole. The reflecting plate is set on the frame, which is used to mask the hole in the frame. The waste heat generated by the light source can be scattered out of the frame through the heat scattering hole of the reflecting plate.

Description

technical field [0001] The invention relates to a direct type backlight assembly, and in particular to a direct type backlight assembly with optimal light source utilization rate and heat dissipation effect. Background technique [0002] With the vigorous development of the liquid crystal display (Liquid Crystal Display, LCD) industry, the product application levels of various liquid crystal display panels continue to increase, and lighter and thinner products are constantly introduced. Since the liquid crystal display panel is a non-self-illuminating display panel, it must rely on light provided by a backlight module to perform a display function. [0003] Generally speaking, according to the position of the light source, the backlight assembly can be divided into two types: side-light type and direct-light type. The edge-lit backlight assembly places the light source on the side of the backlight assembly to reduce the thickness of the backlight assembly, so it is mostly u...
