Description

technical field [0001] The invention relates to a DLP display system, in particular to a laser light source DLP display system and a display control method. Background technique [0002] With the development of DLP display technology and projection technology, breakthroughs in semiconductor laser technology make it more and more used as a projection light source in projection systems. There are two ways to use semiconductor lasers as light sources in projection systems: the first is to use red, green, and blue lasers as three primary colors; the second is to use blue lasers as light sources, while the other two The primary colors (that is, red and green) are produced using a blue laser to excite phosphors that emit light. [0003] The second approach is developing most rapidly because it uses relatively cheap blue lasers. The DLP projection system in which the laser excites the phosphor to emit light is composed of a DLP driver board, a signal processing board, a fluoresce...

Problems solved by technology

In the traditional technology, when the display system is working, no matter what the displayed content is or the environment in which the system works, the light source and the light source driver always work according to the preset working mode. Such a display method cannot make full use of the energy of the light source.
