A Compact Pixel Circuit for Externally Compensated AMOLED Displays

Nonuniformity and aging are two major issues with the pixel circuits of active-matrix organic light-emitting diode displays. External compensation scheme is typically employed to mitigate these two issues, since various off-panel resources, such as on-chip processors and memory arrays, can be utiliz...
