摘要： A pixel element and a liquid crystal display with discharge function are disclosed. In each of the pixel elements of the liquid crystal display, a transistor is disposed between the common electrode and the pixel electrode. The transistor will be turned on by a discharge signal sent from the master control unit of the liquid crystal display when the liquid crystal display is turned on or turned off, so as to provide the same common voltage to both the common electrode and the pixel electrode. Therefore, the positive and negative charges accumulated in the common electrode and the pixel electrode can be removed and the liquid crystal display is well protected.

摘要： A digital-to-analog converter (DAC) is provided for converting an (X+Y)-bit input word, which includes an X-bit MSB subword and a Y-bit LSB subword, into a current signal. The DAC has an X-bit voltage DAC section and a Y-bit current DAC section. The X-bit voltage DAC section generates an intermediate voltage corresponding to the X-bit MSB subword. The Y-bit current DAC section generates a reference current corresponding to the intermediate voltage and outputs the current signal derived by multiplying the reference current by a factor corresponding to the Y-bit LSB subword. In addition, a method for digital-to-analog conversion of an (X+Y)-bit input word into a current signal is also provided.
