Laser backlight source for liquid crystal display system

Abstract

The invention discloses a laser backlight source for a liquid crystal display system. The laser backlight source is much better than the prior liquid crystal display light source in the aspects of color gamut ranges, color brightness and purity fidelity. The laser backlight source has a structure that the laser backlight source comprises a plurality of RGB hexagonal laser diode units which are arrayed at intervals; the bottoms of the RGB hexagonal laser diode units are provided with baffle boards; the upper parts of the RGB hexagonal laser diode units are provided with scatterers; and the upper parts of the scatterers are provided with brightness enhancement films.

Description

technical field [0001] The invention belongs to the field of laser display systems, in particular to a laser backlight source for a liquid crystal display system. Background technique [0002] In recent years, the development of liquid crystal display (LCD) has advanced by leaps and bounds, and its position in the field of flat panel display is also becoming more and more important. LCD TVs, notebook computers, mobile phones, etc. have entered thousands of households, and LCD monitors have become the mainstream display devices in the market today. This stems from the multiple advantages of liquid crystal displays: no radiation, low energy consumption, small heat dissipation, slim and light, and easy to carry. LCD monitors have replaced traditional CRT monitors in most applications, but not completely. The reason is that the color gamut displayed by LCDs is smaller than that of CRTs, and the colors presented are not rich enough. We know that LCD itself does not emit light,...

Problems solved by technology

[0003] Traditional LCD TVs use cold-cathode fluorescent tube backlight (CCFL). Its technology is mature and has a long life, but it also has many disadvantages: first, the color gamut is small, generally only reaching 72% of the NTSC color gamut standard; The cold cathode fluorescent tube contains a small amount of mercury, which does not meet the environmental protection standards; the third is that light leakage is common, it is difficult to start at low temperature, and the response time is slow

However, LED backlight also has its disadvantages. First, its brightness is not high enough, and its power consumption is relatively large, and the range of color rendering is not very large.
