摘要:
A liquid crystal panel (10) includes an active matrix substrate on which a transistor (12), a pixel electrode (17), signal lines (15, 16) and backup wirings (8a, 8b) for recovering a defect in the signal line are formed; a color filter substrate on which a common electrode (counter electrode) is formed; and a liquid crystal material provided between the active matrix substrate and the color filter substrate. The backup wirings (8a, 8b) are (electrically) connected to the common electrode on the color filter substrate, through (i) a protection circuit (9) for discharging an undesired electric charge that occurs in the backup wirings (8a, 8b) and (ii) a sealing adhesive (6). With this configuration, it becomes possible to reduce problems (for instance, unexpected short-circuiting of the backup wiring and the signal line) caused by the undesired electric charge that occurs in the backup wirings.

The display device substrate according to the present invention is arranged so that: a source line is provided on an area on which a pixel electrode is not provided, and a gap is provided between the source line and the pixel electrode, and a black matrix (light shielding film) which covers a surface of the source line overlaps with the pixel electrode. Thus, it is possible to prevent parasitic capacitance (Csd) between the pixel electrode and the source line from becoming uneven in a display area, so that it is possible to reduce display unevenness of a liquid crystal display device using the present display device substrate.

A PDP apparatus, the peak luminance of which has been improved with little modification of the existing circuit structure, has been disclosed, in which a thinning process that shortens an address period by hiding part of display lines in a fixed subfield of a low luminance is performed, the saved time is increased by an amount corresponding to that from which the luminance weight (the number of sustain discharge pulses, that is, the length of the sustain discharge period) of the thinned subfield of a low luminance is subtracted, and the remaining time is allocated at the ratio of the luminance weights on completion of the first step in each subfield.

摘要:
In a display method of a PDP apparatus or the like, there is provided a technique for reducing or eliminating dynamic false contours in a display video image by determining and detecting an occurrence region of dynamic false contours in display data with good accuracy for coping. In a false-contour detection unit in a PDP apparatus, a carry detection unit detects, as a dynamic-false-contour occurrence region, a pixel region corresponding to carry in an SF on-cell pattern of adjacent pixels based on a video image signal in view of a predetermined condition. In a width control unit, a detection region is expanded according to a motion amount. A detection region is expanded according to a motion amount in a width control unit. A diffusion processing (actual gray-scale number restriction processing) based on dither or error diffusion is performed to the detection region. A detection condition of the carry is that an on-cell state of an SF with higher weighting is different between the adjacent gray scales sandwiching the carried gray scale therebetween.

A plasma display device is provided which expresses a video with gradations by selecting each of a plurality of subfields forming one field, each of the subfields having a weighted number of sustain pulses. A sustain pulse number calculation unit calculates a display load factor of an input video signal and calculates a total number of sustain pulses of one field according to the display load factor. A gradation number selection unit selects a gradation number being a sum of weights of all of the subfields according to the calculated total number of sustain pulses.

An active matrix substrate of the present invention includes a TFT and a substrate. The TFT formed on a substrate includes, when viewed in a normal direction of the substrate: a first region in which a gate electrode overlaps a source electrode via a semiconductor layer; a second region in which the gate electrode overlaps a drain electrode via the semiconductor layer; and a third region in which the semiconductor layer overlaps neither the gate electrode, source electrode, nor the drain electrode. The third region includes a portion adjoining the source electrode lying outside the first region and/or a portion adjoining the drain electrode lying outside the second region. The gate electrode includes: a main body, which includes a portion constituting the first region and the second region; and a protrusion from the main body. At least a part of the protrusion of the gate electrode is in between the drain electrode and the portion of the third region adjoining the source electrode, or between the source electrode and the portion of the third region adjoining the drain electrode.
