We have developed a new 12-bit driver IC with linear Digital-to-Analog converter circuits. The driver has a newly proposed pointto-point link interface named PPmL and a new gamma control circuit.The proposed interface can achieve high data-transfer rates that full-HD resolution LCD-TVs require, and our new Digital-to-Analog converter circuits can output any gamma curve controlled with only several hundred bit length parameters

We have developed a novel linear digital‐to‐analog converter using a capacitor coupled adder for LCD driver ICs. The proposed 12bit linear DAC can output 4096 voltage levels from only 128 reference voltages. The die size of the proposed 12bit linear DAC is quite smaller than the conventional non‐linear 10bit Resistor‐Resistor‐String DAC (RR‐DAC).
