Abstract

Abstract : This paper presents a timing controller (TCON) embedded driver (TED) IC with 3.24‐Gbps embedded display port (eDP) which is implemented using a 45nm high voltage CMOS process for the chip‐on‐glass (COG) TFT‐LCD applications. The proposed TED‐IC employs the input offset calibration scheme, the zero‐adjustable equalizer and the PLL based bang‐bang CDR to enhance the maximum data rate. Also the smart charge sharing (SCS) is proposed to reduce the dynamic power consumption of output buffers. Measured result demonstrates the maximum data rate of 3.24Gbps from a 1.1V supply voltage with a 7.9‐inch QXGA 60‐Hz COG‐LCD prototype panel and 44% power saving from the display system.
