碩士 === 崑山科技大學 === 電子工程研究所 === 99 === This paper proposes a way of reducing current consumption of the TFT LCD method. TFT LCD power consumption of the factors used in the TFT LCD source driver of the OP amplifier architecture and panel loading. So the past a rail to rail type OP amplifier to drive a panel of the channel, replaced by a PN type OP amplifier to drive panel of two channels, this approach re-use a specific pattern when, PN type OP amplifier up than rail to rail type OP amplifier to 50% of the province, the current consumption. And then with the original switch used to control the liquid crystal state of the dot inversion switch column inversion of the way, when the two mix and match to compare the differences. Finally, the paper to experiment with different pattern found to white pattern to do the comparison, PN type OP amplifier architecture with column inversion than rail to rail type OP amplifier architecture with dot inversion province to 90 percent of consumption current. To verify the feasibility of the proposed method in this paper.
