dlp projection display drive system supporting multiple laser light sources

Abstract

The present invention discloses a DLP projection display driving system of various laser light sources, which is characterized in that it has a signal processing and a main controller, and the signal processing and the main controller are connected with a video decoding circuit, a DMD driving module, and a fluorescent wheel driving module , color wheel driver module, optical temperature sensor module, laser light source driver interface, power management module, Android smart operating system module, audio processing and power amplifier module; RGB three-color laser light source driver connected to RGB three-color laser module to emit three-color laser; The PMD1000 chip is respectively signal-connected to the laser light source driver, fluorescent wheel and color wheel, and the laser module emits laser light. The fluorescent wheel is provided with phosphor powder, which can be excited to emit fluorescent light of the corresponding color. Different, the hardware driver board does not need to be adjusted, only the corresponding driver interface needs to be plugged in, so as to achieve universal hardware, suitable for DLP projection display drivers of various laser light sources.

Description

technical field [0001] The invention relates to the field of laser display technology, in particular to a DLP projection display drive system supporting multiple laser light sources. Background technique [0002] The development direction of display technology has successively experienced black and white display, color display, and flat panel display. After flat panel display, there will be an era of flexible display. Laser projection display conforms to the development trend of flexible display, and has the characteristics of long life, wide color gamut, high brightness and energy saving. Laser display technology using red, green, blue (RGB) three primary color lasers as the light source. The color gamut coverage rate can reach 90%, and at the same time, it fully inherits the high resolution and digital signal characteristics of the digital age, realizing the most perfect color reproduction in human history. Laser light source is the best light source to meet various high...

AI Technical Summary

Problems solved by technology

In the mainstream laser projection display, there are laser light sources that excite phosphors with blue lasers, and laser light sources with pure lasers in RGB three primary colors. Different laser light sources correspond to different drive systems. There is no one compatible with different laser light sources in the market. Design method of laser projection display drive system
