Abstract
A pixel module comprises a scan driver to output first signals, a data driver to output second signals, and a plurality of pixel circuits for driving an LED with PWM signals. Each pixel circuit comprises a first memory configured to store image data to drive the light-emitting diode, a second memory configured to store charging control data indicating charging timings or a number of charging times of a capacitor, and a PWM pixel driver comprising the capacitor configured to be chargeable when a supply of a bias voltage is turned on based on the charging control data, a charge controller configured to output a charging control signal according to the charging control data, and a PWM control element configured to control a power supply to the light-emitting diode, wherein the second signals transmit the image data to the first memory and the charging control data to the second memory.
