Abstract
A micro-LED display has an array of separately controllable micro-LEDs and corresponding pixel drivers. The pixel drivers have pulse-width modulation (PWM) generator circuits for the LEDs. The PWM generator circuits include the following. N input nodes are coupled to receive N control bits that determine a brightness of the LEDs. An output node is coupled to output the drive signal to the LEDs. Each of N transistors are connected between one of the input nodes and the output node. Each transistor is controlled by a clock signal CKand couples the input node to the output node as controlled by the clock signal CK.
