摘要： A digital image signal is serially transferred to each of pixels through a drain signal line. The digital image signal is sampled at pixel selecting transistors, converted from a serial signal to a parallel signal, and then converted to an analog image signal by a DA converter. This DA converter includes a plurality of capacitor electrodes coupled to a pixel electrode at a weighted capacitance ratio and a clock supplying portion for supplying periodic clock signals to the plurality of the capacitor electrodes in response to the digital image signal. The analog image signal is applied to the pixel electrode. This simplifies a configuration of peripheral circuits of the pixel, and accordingly reduces the frame area of a panel and the number of wiring lines.

摘要： The level of a storage capacitor line changes between two types, an H level and an L level. As a result of this change, the voltage applied to a liquid crystal is shifted so that a sufficient voltage is applied to the liquid crystal to perform a display operation. Then, by changing the voltage value of the difference between a first level and a second level, the contrast and screen brightness are adjusted. Furthermore, the capacitances generated at the locations where the two storage capacitor lines and the data line intersect are set to be substantially the same.

摘要： A voltage boosting circuit performs variable frequency control that gradually increases frequencies of clock signals from a low frequency to a high frequency during a boosting operation period for which a low output voltage of a DC-DC converter when the power is turned on is boosted up to a predetermined voltage. Thus, the frequencies of clock signals may be set according to the boosting operation of the DC-DC converter. Consequently, the operation of the DC-DC converter may be stabilized until the stable operation period is performed after the DC-DC converter starts to operate.
