    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.

    摘要: A gamma correction device and method for a display device are provided, which requires fewer look-up tables and small-size driving voltage generating circuits to generate three sets of driving voltages. A plurality of difference values between three gamma curves R, G, and B and a reference curve is stored in the look-up table. According to the look-up table, a selection signal SEL is obtained based on a gray scale signal. Moreover, a most significant bit (MSB) signal is extracted from the gray scale signal. Then, several analog voltages are generated from a voltage source through voltage division. After that, the selection signal and the MSB signal are decoded so as to select one from the analog voltages and convert to a driving voltage. The driving voltage is used to drive the display device.
