Abstract

See full text

A laser projection apparatus includes a display control circuit, a laser source, and a laser source driving circuit connected to the display control circuit and the laser source. The display control circuit is configured to generate N current control signals corresponding to each of a plurality of frames of images, and select an effective current control signal from the N current control signals. The N current control signals include current control signals that are in one-to-one correspondence with M primary colors of each frame of image, and a hybrid-color current control signal, N is an integer greater than 2, and M is a positive integer. The laser source driving circuit is configured to control the laser source to emit light according to the effective current control signal. Magnitudes of effective current control signals corresponding to at least two of the plurality of frames of images are different.
