Abstract

In this paper, a 6-bit source driver with programmable gamma voltages is proposed for mobile display applications. The gamma voltages of the source driver can be adjusted by the 12-bit data register that is programmed by the serial interface of I2 C and the tuning range of 9 reference voltages is ±315mV with 5m V step. Because 9 output buffers are only used in the source driver for 240/720 output channels, the chip size of the proposed source driver is smaller to 20% and power consumption is lower to 35% than those of the conventional source driver which has an output buffer per channel.
