Abstract :
We will demonstrate a new digital driving technique for AMOLED using DeltaSigma modulation, which mitigates the TFT VT-shift issue with a simple 2-TFT-1-Cap pixel structure. It also solves the false image contour problem while achieving the same or better resolution and relaxed gate scan time compared with PWM. The system is implemented using a 2.2-inch QVGA AMOLED panel and FPGA.
