    • The circuit is to provide a type of level shift circuit that operates correctly even when the input timings of voltages from multiple power sources are different. :evel shift circuit 10 that outputs the output signal of the high voltage source as a response to the input signal of the low voltage source has the following attribute: When feeding of the low voltage source is delayed with respect to feeding of the high voltage source, on the basis of the high voltage source, power-on-reset circuit 20 generates power-on-reset signal PWR.

    • A drive circuit, for example a gate line drive circuit for a TFT liquid-crystal display, having a circuit size smaller than in the past. A TFT drive circuit has the shifting direction of drive data sequentially shifted through shift registers (SR116-R60) and is further inverted by a control signal (SEL_SFT), and the data are shifted in the opposite direction, from the first shift register (SR61) to the second shift register (SR116). At this time, the upper group of switching circuits (SW1-SW56) or the lower group of switching circuits (SW116-SW61) is enabled and the other group is disabled by control signals (SEL_UP, SEL_LO). Once the drive data are shifted to the bits of the shift registers, a voltage selection signal generated by a decoder (DEn) is inputted to an output circuit via an effective switching circuit, and a drive signal for a TFT gate is outputted. The number of circuits is reduced because the shift registers (SR61-SR116) and decoders (DE61-DE116) are shared by two outputs.
    • 驱动电路,例如TFT液晶显示器的栅极线驱动电路,其电路尺寸比以往小。 TFT驱动电路具有通过移位寄存器(SR116-R60)顺序移位的驱动数据的移位方向,并且由控制信号(SEL_SFT)进一步反转,并且数据沿相反方向从第一移位寄存器(SR61 )到第二移位寄存器(SR116)。 此时,开关电路(SW1-SW56)或下组开关电路(SW116-SW61)被使能,另一组被控制信号(SEL_UP,SEL_LO)禁止。 一旦驱动数据被移位到移位寄存器的位,由解码器(DEn)产生的电压选择信号通过有效的开关电路被输入到输出电路,并且输出用于TFT栅极的驱动信号。 由于移位寄存器(SR61-SR116)和解码器(DE61-DE116)由两个输出共享,所以电路数量减少。

    • A thin-film transistor circuit, which is used as a driving circuit for driving pixels in an image display, is constituted of a plurality of thin-film transistors that are formed on an insulating substrate. In each thin-film transistor, a conductive electrode is placed so as to face a gate electrode with a channel region of a polycrystal silicon thin-film that forms an active layer located in between. Here, a constant voltage is applied to the conductive electrode. When threshold voltage is shifted by applying a voltage to the conductive electrode, it is possible to allow the absolute value of the threshold voltage of n-channel-type transistors and the absolute value of the threshold voltage of p-channel-type transistors to become virtually equal to each other. Moreover, it is possible to properly set the threshold voltage in accordance with factors such as the channel length of the thin-film transistors, the types of circuits that are constituted of the thin-film transistors and voltages to be applied to the thin-film transistors. Thus, it becomes possible to remarkably improve the characteristics of thin-film transistor circuits, such as operation speeds and holding characteristics.
