摘要： There are provided: a first logic operation circuit which performs a logic operation using a high-amplitude logic signal; a transmission system having a load capacitance; and a low-voltage signal generator which is a step-down level shifter transforming an incoming high-amplitude logic signal from the first logic operation circuit to a low-amplitude logic signal having a lower amplitude than the high-amplitude logic signal for output to the transmission system. In the configuration, the first logic operation circuit operates based on a high-amplitude logic signal, and is therefore free from malfunctions and performs operations at high speed. Further, the transmission system introducing a load capacitance transmits a low-amplitude logic signal and therefore restrains increases in electric power consumption and occurrence of unnecessary radiation.

摘要： A digital-to-analog converter includes a first converter stage 1 for converting the m most significant bits of a k bit input signal to upper and lower voltage limits VL and VH by selecting the appropriate low impedance reference voltages. A second converter stage 2 performs a linear conversion of the n least significant bits of the k bit input within the voltage range defined by the voltage limits VL and VH. A precharging circuit including switches SW1 and SW2 disconnects the stage 2 from the load CLOAD, which is charged to the voltage limit VL during the precharge phase. The load is subsequently disconnected from the voltage limit VL and connected to the output of the stage 2 to complete charging of the load CLOAD to the converter output voltage.

摘要： Each of a plurality of source lines is connected to a video signal line via an analog switch and a read-out switch, which are turned ON/OFF by a source line driving circuit. When the analog switch of the source line is turned ON and the read-out switch thereof is turned OFF, the selected source line is connected to the video signal line, thereby writing a video signal to a storage capacitor of a picture element via a picture element transistor. When the analog switch of the source line is turned OFF and the read-out switch thereof is turned ON, a signal stored in a storage capacitor is read out from the source line to the read-out line via the picture element transistor. The read-out line is a single line shared by the plurality of source lines.
