We have implemented a 240Hz 55‐inch ultra definition (UD, or 3840times2160) resolution TV panel using amorphous IGZO TFT. As the resolution and the frame rate of a panel increase, pixel charging time and panel transmittance ratio decrease. Among various data driving architectures, the data single 1G1D driving renders cost benefit, process competitiveness and design flexibility. To apply this driving architecture to a high resolution, high mobility of TFT and low RC delay are required. We suggest a‐IGZO TFT and copper metallization technology as a solution.
