Abstract
A display system includes a light emitting array and a driving circuit. The light emitting array includes: a plurality of scan lines, a plurality of channel lines, and a plurality of light emitting elements connected to the scan lines and the channel lines. The driving circuit includes: a delay-locked loop generating an internal global clock signal; a signal processor generating a scan control output and a channel control output based on the internal global clock signal and display data; a scan driver driving the scan lines based on the scan control output; and a channel driver providing a plurality of driving current signals respectively to the channel lines based on the channel control signal.
