Abstract
Embodiments provide an active matrix LED pixel driving circuit and pixel layout for increased uniform illumination of LED display panels. A plurality of sub driving transistors can be located in neighbor pixels of the pixel associated with the prime driver transistor's LED. The sub driving transistors can compensate for the process variations affecting the threshold voltage variation of the prime driver transistor resulting in uniform illumination of LED's on the display panel.
