Abstract
AbstractThis paper proposes an Unequaled Single Source Driver (USSD) with multi‐chip topology to achieve large source driver outputs for WXGA resolution TFT‐LCD. The proposed driver used a multi‐domain power scheme in a chip, and was implemented by using a Bipolar CMOS DMOS (BCD) process. It incorporated a LVDS/MIPI combo receiver, timing controller, level shifter, charge pump, boost, inverter, and LED driver in a source driver to generate multiple power supply to the panel. Furthermore, the integral chip bus (iCB) with embedded code technique was used to synchronize data indices of color engines and control between the applications of multi‐chips. The proposed USSD was verified by a 15.6‐in WXGA TFT‐LCD, in which the 1 Gbps data rate was achieved by multi‐drop mobile industry processor interface.
