Abstract
A driving method for improving uniformity of the brightness of pixels in an OLED/PLED display is provided. The method controls the light-on signal according to the driving display data after it is loaded, so that the pulse-width of the light-on signal is function-ally dependent of the quantity of OLED display pixels to be lit-on. Hence, any brightness uniformity of the OLED/PLED display due to insufficient circuit driving capacity is significantly improved.
