Abstract

A pixel current driver based on a current mirror comprises a plurality of thin film transistors (TFTs) driving OLED layers. The plurality of thin film transistors may be four thin film transistors formed in a current-programmed .DELTA.V T-compensated manner. Other versions of the current-programmed circuit with different numbers of thin film transistors are also presented that compensate for .delta.V T.
The OLED layer are continuous and vertically stacked on the plurality of thin film transistors to provide an aperture ratio close to 100%.
