Abstract

Switched-current (S-I)-type pixel circuits are widely studied for high-performance active-matrix organic light-emitting-diode displays but suffer significant sampling and hold (S/H) nonidealities. In this letter, a simple and effective capacitive compensation method is proposed to suppress the S/H nonidealities and, thus, to greatly improve the current-reproducing accuracy and the output linearity of the circuits. The analysis procedure clearly demonstrates the operation mechanism of the method, and the simulation results of Simulation Program with Integrated Circuit Emphasis prove its excellent applicability for S-I pixel circuits.
