Abstract
An LED display system has an LED display panel coupled to a driver circuitry. The driver circuitry includes a scrambled PWM generator, a register, and a memory. The driver circuit receives an image data from an external source and, after certain compensations, the compensated data is sent to the scrambled PWM generator to be distributed according to a new set of rules. Compared with existing technologies, this LED display has a host of benefits, including having a uniform optical energy output at low brightness.
