Abstract

The invention discloses a projection light source drive and control circuit. The projection light source drive and control circuit provided in an embodiment of the invention comprises a light source gate control module, a first drive logic module, a second drive logic module, a third drive logic module, a red laser light output unit, a blue laser light output unit and a green laser light output unit; the projection light source drive and control circuit can optionally be connected to a double color laser light source or a three color laser light source via a plurality of logic signals; the projection light source drive and control circuit can be suitable for drive and control of a plurality kinds of laser light sources, compatibility and universality of the projection light source drive and control circuit can be achieved, and an application range of the projection light source drive and control circuit can be expanded.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a projection light source drive control circuit. Background technique [0002] With the development of science and technology, there are more and more scenes that need to use laser projection products. In order to obtain better projection effects, people pay more and more attention to the way that the driving control circuit in laser projection products drives and controls the laser light source. [0003] Due to the high color purity, strong directivity, high brightness, high color gamut and many other advantages of the laser light source, it is gradually used in projection products by merchants. When a two-color laser light source is used in a laser projection product, the two-color laser light source is a red laser The light source and the blue laser light source, the red laser light source can output red light under the control of the two-color light source drive circuit, and th...
