Abstract:
A display device comprises a first LED coupled with an input node, and further comprises pixel driver circuitry. The pixel driver circuitry comprises a data input transistor configured to conduct, based on a first control signal, a data signal across a first channel having a first channel W/L ratio. The pixel driver circuitry further comprises a drive transistor configured to conduct, based on the data signal, current across a second channel into the input node. The second channel has a second channel W/L ratio. The pixel driver circuitry further comprises a reset transistor configured to conduct, based on a received second control signal, a first reference voltage signal across a third channel into the input node. The third channel has a third channel W/L ratio. At least one of the first channel W/L ratio, the second channel W/L ratio, and the third channel W/L ratio is different.
