Problems solved by technology

However, using multi-color LEDs as light sources will cause uneven light mixing. Therefore, the current practice is to increase the light mixing distance, but this will reduce the efficiency of light use and increase the size of the product, which cannot meet the requirements of light and thin information display products. needs

Embodiment Construction

[0052] Please refer to FIG. 2 , which is a schematic side view of the first embodiment of the light source system of the present invention. The light source system 50 includes at least an optical conversion module 52, the red light source is located on the left side of the optical conversion module 52, and the green light source and the blue light source (only one light source is drawn as a representative) are located on the right side of the optical conversion module 52, wherein The above-mentioned light sources are all LED light sources. The optical conversion module 52 includes two polarizing elements 54, 56, a polarization modulating element 58 arranged between the first and second light polarizing elements 54, 56 and a reflective film 64, which is arranged between the first and second light polarizing elements. Underneath the chemical elements 54 and 56 is preferably a half phase retardation film. The first and second light polarizing elements 54 and 56 are made of doubl...

Abstract

The invention provides a light source system which comprises an optical transformation module, a first color light source and a second color light source; wherein the first and the second light sources are respectively and oppositely equipped on two sides of the optical transformation module; furthermore, the color light radiating from the first and the second color light sources can mix into white light; the optical transformation module comprises a polarization regulating element and a light polarization element, both of which can divide the light radiating from the first and the second color light sources into single polarization component; then the single polarization component radiates from the optical transformation module.

Description

technical field [0001] The invention relates to a light source system, in particular to a light source system which uses a color light-emitting diode as a light source and can provide a white light source with a single polarization component. Background technique [0002] Due to the characteristics of thin and light appearance, low power consumption and no radiation pollution, liquid crystal display is a display device that is becoming more and more popular at present, and has been widely used in personal desktop computer screens, notebook computers, personal digital assistants ( PDA), mobile phones and other portable information products, and gradually replace the cathode ray tube (Cathode Ray Tube, CRT) monitor and traditional TV. [0003] Generally speaking, a liquid crystal display module (LCM) is the most critical device in a liquid crystal display, which includes components such as a liquid crystal display panel and a backlight module. A liquid crystal display panel h...
