A new pixel circuit for “clamped inverter driving” was developed. Since a PMOS inverter is applied instead of the conventional CMOS for the pixel circuit, the circuit is simplified and is composed of only three TFTs. A simulation of gray‐scale characteristics verified that this pixel circuit can compensate variation in V th and carrier mobility. A 2.5‐inch OLED display based on the new pixel circuit was fabricated by LTPS processing and achieves 6‐bit gray‐scale and good uniformity.
