摘要： An inverter includes an input inverter having a high-resistance load and a first transistor and an output buffer including second and third transistors coupled in series. A power supply voltage is provided to satisfy an inequality VDD1>VDD2+Vth where VDD1 is the power supply voltage of the input inverter, VDD2 is the power supply voltage of the output buffer, and Vth is the threshold voltage of the transistors. Use of the high-resistance load allows an output waveform to rise and fall quickly, as well as reduces current consumption.

摘要： The present invention provides a display device which is used in a miniaturized portable information device, wherein the display device requires a small mounting area for a driving circuit thus realizing free mounting of the driving circuit and also can perform driving thereof with a low-voltage power source such as a battery. In a display device which includes a display panel and a driving circuit on the same substrate, a booster circuit is formed on one side of a display panel together with the driving circuit and is formed by steps substantially equal to steps for pixel transistors. The booster circuit includes a circuit which compensates for the lowering of voltage of a switching element used in the booster circuit attributed to a threshold value of a switching element.

摘要： A display device has pixels, signal lines coupled to the pixels, and a video signal drive circuit for supplying signals to the signal lines in parallel, based upon data transferred serially from an external system. The video signal drive circuit includes plural stages each formed by a column of switching elements. The switching elements of each stage double successively in number as a final stage is approached. Each of the switching elements of each stage excluding the final stage is connected to a pair of switching elements in a succeeding stage. Each of the pair of switching elements is repeatedly and alternately switched ON with the other of the pair of switching elements being switched OFF, and a frequency of the ON-OFF switching of the pair of switching elements of each stage is successively halved as the final stage is approached.
