摘要： With regard to a display device having an SRAM incorporated in a pixel, a technology is disclosed, which is capable of reducing manufacturing costs by simplifying a constitution of a driver. A write voltage equivalent to white or black represented by a tone level of a normal display area is converted into a write voltage corresponding to a brightest white display or a darkest black display in the pixel, and is held in the SRAM of each pixel. In the case of normal display, display is carried out with the write voltage represented by the tone level of the normal display area. In the case of static image display, display is carried out with the write voltage corresponding to the brightest white display or the darkest black display in the pixel, the write voltage being held in the SRAM. Since the normal display and the static image display can be carried out with a write voltage supplied from one driver, the constitution of the driver can be simplified.

摘要： A liquid crystal display realizes high resolution without enlarging a frame area of an array substrate in the display. The display connects analog switch pairs each consisting of a p-TFT and an n-TFT to signal lines, respectively. Among the TFTs, those having the same polarity and connected to adjacent signal lines are provided with drain electrodes that are connected to a video bus through a common contact hole. Sharing the contact holes among the TFTs enables the switch pairs to be juxtaposed at fine pixel pitches.

摘要： A signal line drive circuit according to the present invention has: a latch circuit which latches digital pixel data; a D/A converter which converts a latch output from the latch circuit into an analog video signal; an AMP which amplifies the analog video signal converted by the D/A converter; and a signal selection circuit which selects a signal line to which the analog video signal amplified by the AMP is supplied. The AMP has: an odd number of inverters which are cascade-connected; capacitor elements which are respectively connected between stages of the inverters and between an input terminal of the inverter on a first stage and an output terminal of the inverter on a last stage; a first power supply line which supplies a power supply voltage to the inverter on the first stage; and a second power supply line which supplies a power supply voltage to inverters other than the inverter on the first stage. The accuracy of the AMP can be improved by separating the power supply line for only the inverter on the first stage.

摘要： In order to reduce the scale of drive ICs and to prevent uneven display in signal line selective drive, in this liquid crystal display device, for each group in which one video output line corresponds to N signal lines, the signal line is switched and connected to the video output line via an analog switch ASW. Thus, the number of the video output lines is reduced to 1/N. Moreover, as to an Lth scan line, for each of the groups, a signal line to which a video signal having its polarity inverted between an L-1th scan line and the Lth scan line is supplied is selected first and a signal line to which a video signal having its polarity not inverted is supplied is selected later. Thus, a video signal in which a polarity is not inverted and no potential change occurs is supplied to the signal line later.

摘要： In forward direction pulse shift, by turning off a sixteenth transistor, a through-current is prevented from flowing between the fifth transistor and the seventh transistor. In backward direction pulse shift, by turning off the fifteenth transistor, a through-current is prevented from flowing between the fifth and sixth transistors. Thus, a potential variation in an output signal of a shift register between the forward direction pulse shift and the backward direction pulse shift is prevented.
