摘要:
A switching circuit selects a display control circuit in an image display period, and selects a detection control circuit in an x-coordinate detection period. A row electrode drive circuit outputs row electrode scanning pulses in the image display period to sequentially scan row electrodes. A column electrode drive circuit outputs column electrode scanning pulses in the x-coordinate detection period to sequentially scan column electrodes. A coordinate detection circuit detects coordinates at a tip end of a detection pen based on an induction voltage induced at a tip electrode of the detection pen due to the scanning pulses. Accordingly, by detecting a y-coordinate at the tip end of the electronic pen in the image display period and detecting the x-coordinate in the x-coordinate detection period, a display-integrated type tablet device can achieve an increase in area of its display screen, high productivity, cost reduction, and high coordinate detection accuracy.

A liquid crystal display panel is so constructed that a plurality of pixels are arranged in a matrix form having the number of lines twice that of horizontal scanning lines for one field of interlaced scanning video signals obtained by scanning an original image every other line, the arrangement of the pixels being shifted horizontally by one-half of a pixel between adjacent upper and lower lines. A row driving circuit applies, to the pixels in the upper line of the two adjacent upper and lower lines, data voltages obtained by sampling a video signal representing one horizontal scanning line by a clock signal of the timing that matches the number of pixels in the upper line and the arrangement of the pixels, and applies, to the pixels in the lower line, data voltages obtained by sampling the above video signal representing one horizontal scanning line by a clock signal of the timing shifted by 1/2 cycle from the above clock signal. Thus, one horizontal scanning line represented by the video signal is displayed using the two upper and lower lines of pixels, thereby enhancing the display quality of the produced image.

The invention relates to a drive apparatus for a liquid crystal display device. The voltage, to be applied to longitudinally and latitudinally arranged liquid crystal cells of the liquid crystal display device, is altered in polarity from field to field and from frame to frame, whereby the occurrence of flicker is prevented. The field discriminating device counts the numbers of lines in first and second fields by synchronizing a vertical synchronizing signal at a leading point of a field time. Thereafter the difference in the number of lines between the first and second fields is detected, the field times being thereby discriminated. When a video signal is erroneous, the field discriminating device provides a field discriminating signal, the level of which is changed alternately from field time to field time.

摘要:
A liquid crystal panel having pixel-forming portions that are assigned dispersedly to two mutually adjacent rows of pixels sandwiching the scanning signal line Lg from above and below, in a horizontally periodical pattern having a cycle of “up down, up” or “down, up, down” as to which of the up row and the down row is selected in the assignment of three pixel electrodes. This staggered structure provides a quasi dot inversion driving method while reducing vertical shadow when displaying e.g. the “checker back”.
摘要:
In a matrix display device, when cells of first to third colors composing one pixel are first to third cells, the second cell is disposed on one side of the first cell in a signal line alignment direction while disposing the third cell on the other side of the first cell in a scanning line alignment direction, and the first to third cells form the shape of a letter L. One pixel and another pixel adjacent to either side of the former pixel in the scanning line alignment direction are a first pixel in the shape of the letter L and a second pixel in the shape of the letter L and in a state rotating by 180° with respect to the first pixel, respectively. The first and second pixels are paired with each other and a combination of these pixels form the shape of a square, where all the first pixels and all the second pixels respectively have the same combination of colors of the first to third cells, and the first and second pixels have a difference in disposition of colors, thus realizing high-definition display with a low-cost arrangement.
