摘要： The liquid crystal display device (1) includes a liquid crystal panel (69) having, for each of pixels (60), a digital memory element (68) for holding an electric potential according to image data and a liquid crystal cell (64) for displaying an image by receiving the electric potential from the digital memory element (68); and a liquid crystal driver circuit (10) having an AC control section (22) for reversing a polarity of an AC voltage applied to the liquid crystal cell (64) on a given cycle and an image transmission control section (21) for issuing instruction on outputting of image data to the liquid crystal panel (69). In a case where an image data transmission period contains a period during which a voltage in the liquid crystal cell (64) is reversed in response to a polarity reversal of the AC voltage applied to the liquid crystal cell (64), the image transmission control section (21) causes image data to be outputted to the liquid crystal panel (69) after the polarity reversal of the voltage in the liquid crystal cell (64) is completed. This makes it possible to (i) prevent a decrease in reliability of liquid crystal, (ii) update, without rewriting data, an image to be displayed, and (iii) prevent a deterioration in quality of a displayed image.

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.
摘要翻译：根据本发明的图像显示器包括执行脉宽调制驱动的驱动装置，抑制功耗，并产生良好的多色调显示。图像显示使扫描线电压和信号线电压之间的差异在正极性写入和负极性写入中相等，通过该驱动将像素交替驱动，以使晶体管的导通电阻相等。这允许首先确定最大脉冲宽度，开关元件的尺寸等，使得它们匹配开关元件的电阻值上升的正极性写入。不需要高频时钟来产生负极性写入中的电荷比的微妙差异，其中开关元件的电阻下降。取决于时钟频率的功耗也会下降。

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. The main panel 200, sharing the source driver 15 with the first liquid crystal panel 10, is less frequently used for display than the first liquid crystal panel 10, and is disconnected by the switching TFT 17 when only the sub panel 100 is used. This makes it possible to device a twin-panel display device low in electric power consumption.
