Abstract: A minimum electric potential of electric potentials (source waveforms (VS)), which are applied, in accordance with image data, to source terminals of respective switching elements each being a thin film transistor provided in a corresponding picture element, is set to be lower than a ground electric potential. This makes it possible to provide a liquid crystal display device in which each picture element is difficult to accumulate an electric charge when a power supply is turned off.

Abstract: While a power supply to a liquid crystal display device (100) is being turned off, a control circuit (2) sets a switching cycle of a gate bus line, via which writing is carried out, shorter than that during image display and carries out power-off processing in which a given voltage for power-off processing is applied to each source bus line. This makes it possible to provide, without greatly increasing a device cost, a liquid crystal display device capable of preventing a voltage from continuing to be applied to a pixel while the power supply is being turned off.

Abstract: The driving circuit of the liquid crystal display device according to the present invention classifies a combination of a displayed gray-scale level of a previous vertical scanning period and a regular gray-scale level corresponding to an input image signal in a current vertical scanning period into either a first group or a second group. The driving circuit is capable of supplying the gray-scale voltage corresponding to the regular gray-scale level for any combination belonging to the first group, and supplying a gray-scale voltage corresponding to an alternative gray-scale level which is different from the regular gray-scale level for any combination belonging to the second group.

Abstract: In one embodiment of the present invention, a display apparatus includes a liquid crystal display panel including: video signal lines to supply a data signal; scanning signal lines provided so as to intersect the video signal lines; and pixel electrodes provided at intersections of the video signal lines and the scanning signal lines via switching elements, respectively; and a scanning signal line drive circuit for supplying a scanning signal to each of the scanning signal lines. The display apparatus further includes a slope generating circuit which generates a falling slope signal in accordance with the signal delay transfer characteristic of the scanning signal lines, determined by the length of the display panel. The falling slope signal controls a scanning signal so that the scanning signal has a substantially equal slope at its fall regardless of its position on each scanning signal line. The falling slope signal is supplied to the scanning signal line drive circuit.

Abstract: A liquid crystal display device according to one embodiment of the present invention includes a display controller for outputting an image to each panel independently so that the images displayed on a first panel and a second panel are stacked with each other to form one image corresponding to an image source. The display controller includes a luminance ratio adjusting section which adjusts the gray scales of the image outputted, to each liquid crystal panel so that a display response period becomes shorter than a standard predetermined display response period in combining the gray scales, when one combined gray scale is obtained by combining the gray scales of the image outputted to each panel. This allows enhancement in contrast and moving image performance so as to realize a liquid crystal display device having high quality in displaying not only still images but also moving images.

Abstract: In one embodiment of the present invention, a liquid crystal display of the present invention contains an LCD (1) and an LCD (2). Adjacent pairs of polarizers form crossed Nicols. When the LCD (1) produces a display from a first display signal, the LCD (2) produces a display from a second display signal obtained from the first display signal. The gate driver for the LCD (1) and the gate driver for the LCD (2) producing a display from the second display signal are disposed symmetric. Accordingly, flickering is reduced which otherwise would be clearly visible when the two liquid crystal panels are stacked. A liquid crystal display with high display quality is thus realized.

Abstract: A liquid crystal display is driven at, for example, a frame frequency of 100 Hz or higher. There are provided a base-4 frame counter 2 and a source control signal generator section controlling the polarity of the liquid crystal in pixels so as to alternately repeat, for each frame, a horizontal reversal once every m lines (m is 2 or a greater positive integer) and a horizontal reversal once every m lines after shifting the polarity of the lines in the preceding frame by n lines (n is a positive integer equal to a half or less of m). The provision achieves a liquid crystal display and a method of driving the display, addresses insufficient charging at higher frame frequencies and accomplishing higher display quality.

With this arrangement, it is possible to freely switch on the display screen of the liquid crystal panel between a wide viewing angle display and a narrow viewing angle display.
