Luminous element, plane illuminant and direct-light-type backlight module

Abstract

The invention relates to a lighting element which comprises a substrate, two red lighting chips on substrate, two green lighting chips, and a blue lighting chip. Wherein, said lighting chips are arranged on substrate from red, green, blue, green, and read; said lighting chips are connected to the substrate; the red, green, and blue lighting chips comprises red, green, and blue quantum points; the lighting chips with quantum points have more uniform brightness then general chip and code cathode florescent tube. The invention also provides a relative plane light resource and upright back light mould.

Description

【Technical field】 [0001] The invention relates to a light-emitting element, a plane light source using the light-emitting element and a direct-type backlight module using the plane light source. 【Background technique】 [0002] In recent years, with the colorization and enlargement of liquid crystal displays, their application fields are more extensive, such as notebook computers, desktop computers, and LCD TVs. [0003] Since the liquid crystal panel itself cannot emit light, it is a passive component. A light source module, such as a backlight module, is required to provide a side light source for displaying screen images. [0004] Backlight modules can generally be divided into two types: edge-lit and direct-lit. For small and medium-sized LCD panels, the edge-lit backlight module has the advantages of light weight, thin profile, and low power consumption. However, with the development of science and technology, the demand for large-size LCD panels is increasing day by d...

Problems solved by technology

However, the plurality of parallel CCFL tubes are discontinuous tubes one by one, and the brightness and chromaticity of each tube are likely to cause differences, resulting in poor lighting effects.

Moreover, the cold cathode fluorescent lamp contains mercury. When the cold cathode fluorescent lamp is damaged or recycled, it will easily cause the leakage of mercury vapor, pollute the environment, and do not meet the requirements of environmental protection.
