摘要： In the active matrix display device with a DRAM as the retaining circuit, the voltage retained in the retaining circuit is set in the brightness saturation region, which is outside the region of the voltage used in the moving picture display mode. With the voltage in this region, the difference in the brightness will not be recognized even if the voltage decreases before the refreshing operation. This prevents flickering and improves the display quality.

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.

摘要： A digital image signal fed from the drain signal line is written into a retaining circuit through a pixel element selection TFT and a liquid crystal displays an image based on the digital image signal. In the retaining circuit, a threshold voltage of the first inverter circuit is set smaller than a threshold voltage of the second inverter circuit. Therefore, false writing of the image signal data into the retaining circuit can be prevented, leading to an accurate display the image signal retained in the retaining circuit.
