Ultra Definition 240Hz 55-inch LCD TV driven by 1G1D with oxide semiconductor TFTs Copper signal lines

摘要

We have implemented a 240Hz 55-inch ultra definition (UD, or 3840×2160) resolution TV panel using amorphous IGZO TFT. Among various data driving architectures, the data single 1G1D driving renders cost benefit, process competitiveness and design flexibility. So we suggest a-IGZO TFT and copper metallization technology as a solution.
