摘要： A common voltage adjustment circuit. The common voltage adjustment circuit is applied in a liquid crystal display panel having a plurality of display units, coupled to a common electrode. The common voltage adjustment circuit has a first register, a second register, a first digital-to-analog converter, a second digital-to-analog converter, and a regulator. The common voltage adjustment circuit adjusts AC voltage and DC voltage of the common voltage and provides the adjusted common voltage to the common electrode.

摘要： A data driver for a TFT-LCD. N1 channels of the data driver can be disabled. The data driver comprises a multiplexer and a shift register. The multiplexer receives a horizontal start pulse and at least one control signal. Output signals are transmitted from output terminals of the multiplexer according to the control signals. The shift register receives a clock signal and the output signals and generates a start pulse. The start pulse determines to provide a first image data at a first channel or a (N1+1)th channel according to which output terminal the signal is output from.

摘要： A controller switching a display mode of a display panel. A processor provides a first initial signal and switches to a first display mode when a select signal is asserted. A gate driver simultaneously activates the gate electrodes in a first gate electrode group when receiving the first initial signal, sequentially activates the gate electrodes in a second gate electrode group when the first gate electrode group is activated, and simultaneously activates the gate electrodes in a third gate electrode group when the second gate electrode group is activated. A data driver provides corresponding image data to a data electrode depending on the activated gate electrodes when the first, second, or third gate electrode group is activated.
