An Intra-panel Interface for Large Size FPDs with High Resolution And Definition

This paper describes an intra-panel interface which can be applied to a large panel with high resolution and high definition. For good signal integrity and low electro-magnetic interference level, four level signaling is used. And to reduce PCB size, point to point signaling is used. The interface supports WUXGA, 12 bit color depth panel which has larger than 30 inch size. It is designed with a 0.18 um CMOS process. And measurements show it works properly in 25 cm long PCB, which is the same condition of 30 inch panel size.
