Abstract:
1. A pixel in a row of pixels of an active matrix light-emitting diode (AMLED) display with a refresh cycle time, comprising: a first switch coupled in series between a voltage source and a ground; a second switch, the second switch coupled in series with the first switch; a light-emitting diode (LED) coupled in series between the first and second switches and the ground; a first pulse-width modulation (PWM) driver configured to energize the LED for a first specified time period by operating the first switch in a staggered fashion after the passage of a second time period that is equal to a multiple of a pixel row programming time delay, the multiple of a pixel row programming timing delay extending from the energizing of an LED illuminating a pixel in a previous row; and a second PWM driver configured to extinguish the LED by operating the second switch after the first specified time period has elapsed, the first specified time period being less than the refresh cycle time.
