79‐3: Development of Low‐Cost and Narrow‐Border Automotive Panel by DeMUX of IGZO‐TFT

We have developed a high‐mobility, highly reliable IGZO‐TFT, and have achieved higher definition and narrower border for medium‐sized displays such as tablets and notebook PCs. This time, we have developed BCE IGZO‐TFT that satisfies DeMUX in order to narrow the frame at the bottom of automotive displays, which has been difficult until now. High mobility is required to realize DeMUX. To achieve this, we added an extra metal layer to the conventional BCE structure TFT, creating a Double Gate structure. In addition, by using DeMUX, we were able to reduce the cost by reducing the source driver to a single chip.
