Abstract:
The present disclosure relates generally to semiconductor lasers and laser projection systems. According to one embodiment of the present disclosure, a method of operating a laser projection system is provided. According to the method, the laser projection system is utilized to display a sequence of pixelized image frames comprising an alternating sequence of relatively high intensity active projection periods ModON and relatively low intensity inactive projection periods ModOFF. A complementary control signal transitions between an active state QON during the relatively high intensity active projection periods ModON and an inactive state QOFF during the relatively low intensity inactive projection periods ModOFF. The transition of the complementary control signal from the inactive state QOFF to the active state QON is conditioned to anticipate initiation of relatively high intensity active projection periods ModON such that it is optimized upon initiation of the relatively high intensity active projection periods ModON. Additional embodiments are disclosed and claimed.
