摘要： A level shift circuit basically has a configuration connecting two CMOS inverter circuits in parallel, furnishes an input signal to a control terminal of the inverter circuit, obtains an output signal from an output terminal of the inverter circuit, and has a function for level shifting the voltage amplitude of the input signal to the voltage amplitude of the supply voltage of the inverter circuit. The signal that is input by the gate terminal of an n-channel transistor arranged in each of two current paths forming the level shift circuit is not a direct input signal but a signal that is supplied by adding an offset corresponding to the threshold of each n-channel transistor with respect to the voltage amplitude of the input signal via the input voltage converter circuit.

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： When a switching TFT is switched on, a data voltage on a data line is stored in a storage capacitor as a gate voltage of a driver TFT. In this state, a voltage on a pulse drive line is caused to fall. AMOS type capacity element having a second electrode connected to a reference voltage is connected to a gate of the driver TFT. The MOS type capacity element is in an ON state before a fall of the pulse drive line and becomes an OFF state during the fall, and a capacitance changes at the switching of ON state to the OFF state. Therefore, the slope of fall of the gate voltage changes, and the gate voltage after the fall on the pulse drive line can be corrected corresponding to the variation in the threshold values among driver TFTs.
