A 640-channel 6-bit LCD column driver with a cross-self-bias push-pull buffer is presented. To design a column driver for thin-film transistor liquid-crystal displays (TFT-LCDs), both low power consumption and chip area are key problems that must be solved. Therefore, the proposed cross-self-bias buffer amplifier effectively reduces the circuit area and power consumption overheads of conventional...
An output buffer with slew-rate calibration for different TFT-LCD loadings is presented. Unlike other output buffers of column drivers, the proposed output buffer adjusts the output current according to the loading capacitors. The settling time and slew-rate of the proposed output buffer are thus fixed in an acceptable range for different TFT-LCD loading capacitors, allowing more accurate color quality...
A compact low-offset voltage and low power rail-to-rail output buffer for TFT-LCD panel is presented in this paper. Compared to other push-pull output buffers, the proposed output buffer has self-bias circuit which can achieve the smaller area and the lower power consumption. Two complementary push-pull output buffers drive a pair of column lines realize the rail-to-rail driver construction. In addition,...
