Abstract
The invention relates to a light beam generating device and method, and a projection device. The light beam generating device is configured to receive a color control signal and generate a target light beam having a target color, and includes a plurality of drivers, a current signal generating circuit, and a control circuit. The drivers respectively drive a plurality of light-emitting elements according to a plurality of current signals, wherein the plurality of light-emitting elements collectively generate the target light beam. The current signal generating circuit is coupled to the drivers and generates the plurality of current signals according to the color control signal corresponding to the target color. The control circuit is coupled to the drivers and controls whether each driver is enabled according to the color control signal.
