摘要： The present invention provides an active matrix display device, including: a data signal line drive circuit mounted by COG (Chip On Glass) bonding; a photosensor, which is included in a display region, for (i) detecting light intensity and (ii) sending out an analog output serving as a signal indicative of the detected light intensity; and a common electrode (COM) to which a voltage being AC-driven is applied. The data signal line drive circuit includes an analog-to-digital conversion circuit which converts the analog output supplied from the photosensor into a digital output. The conversion is carried out during a first period, which overlaps none of (a) a time point at which each of the scanning signal lines starts being in a selected state, (b) a period during which data signals are sent out to respective data signal lines, and (c) a time point at which the voltage of the common electrode changes. Accordingly, it is possible to provide a display device employing a COG technique, which is capable of carrying out analog-to-digital conversion of the analog output supplied from the photosensor.

摘要： An image display according to the present invention includes a driving device which performs pulse width modulation drive, restrains power consumption, and produces a good multi-tone display. The image display makes the difference between the scan line voltage and the signal line voltage equal in positive polarity writing and negative polarity writing by which pixels are AC driven, so as to make the on-resistances of transistors equal. This allows a maximum pulse width, the size of switching elements, etc. to be determined first so that they match positive polarity writing in which the resistances value of the switching elements rise. No high frequency clock is required to produce subtle differences of charge ratio in negative polarity writing in which the resistances of the switching elements fall. Power consumption which depends on the clock frequency drops too.

摘要： The sub panel 100, having a plurality of gate bus lines 14, source bus lines 16, TFTs 25 and pixel electrodes, is provided with a source driver 15. The main panel 200 has a plurality of gate bus lines 24, source bus lines 16, TFTs 25 and pixel electrodes, each of the source bus lines 16 being connected to the corresponding source bus lines 16 of the first liquid crystal panel 10 through a switching TFT 17.

摘要： A matrix type display device capable of receiving more than one video signal, which displays an image based on a first video signal with a smaller aspect ratio than an aspect ratio of a screen in width by inputting a second video signal in sync with a first video signal to at least a part of column drivers corresponding to a remaining portion on the screen where the image based on the first video signal is not displayed, so that the processing of the first and second video signals is started at the same time and carried out at the same timing. Consequently, the present matrix type display device can readily display a natural image based on an input video signal with a smaller aspect ratio than the that of the screen.
