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

Abstract

The invention discloses a DLP projection display drive system for multiple laser sources. The DLP projection display drive system for multiple laser sources is characterized by comprising a signal processing and master controller, wherein the signal processing and master controller is connected with a video decoding circuit, a DMD drive module, a fluorescent wheel drive module, a color wheel drivemodule, a light temperature sensor module, a laser source drive interface, a power management module, an android intelligent operating system module, and an audio processing and power amplification module, an RGB three primary colors laser source driver is connected with an RGB three primary colors laser module emitting three colors of laser, a PMD 1000 chip is connected with a laser source driver, a fluorescent wheel and a color wheel separately through signals, the laser module emits laser, and the fluorescent wheel is provided with fluorescent powder that can be stimulated to generate fluorescent light of a corresponding color. According to the type of the selected laser source, no adjustment is performed on a hardware driver board, the DLP projection display drive that is suitable formultiple laser sources and is used on hardware universally can be realized only by inserting in a corresponding drive interface.

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...
