Laser projection apparatus and method for driving laser source assembly

A laser projection apparatus, comprising:

• a laser source assembly configured to provide illumination beams;
• an optical engine configured to modulate the illumination beams with an image signal to obtain projection beams;
• a projection lens configured to project the projection beams into an image;
• a display control circuit coupled to a signal shaping circuit and a laser source driving circuit, the display control circuit being configured to output a first driving signal and a second driving signal, the first driving signal including one of an enable signal and a current control signal, and the second driving signal including another of the enable signal and the current control signal;
• the signal shaping circuit coupled to the laser source driving circuit, the signal shaping circuit being configured to shape the first driving signal based on a shaping signal to obtain a target driving signal, and a frequency of the target driving signal being higher than a frequency of the first driving signal;
• and
• the laser source driving circuit coupled to the laser source assembly, the laser source driving circuit being configured to receive the second driving signal and the target driving signal, and drive the laser source assembly to be turned on or turned off in response to the second driving signal and the target driving signal.
