    摘要: A liquid crystal halftone display system including a tone generator which, for pixels having P tones of K tones (1≦P≦K), alternately outputs first N-bit tone display data and second N-bit tone display data in successive frames at one of a first phase and a second phase. Within a block of pixels, the tone generator alternately inverts the phase of the N-bit tone display data at successive first pixels having different ones of the P tones within the block of pixels beginning at a left side of the block of pixels, and alternately inverts the phase of the N-bit tone display data at successive pixels having a same one of the P tones within the block of pixels beginning at the left side of the block of pixels.

    摘要: A liquid-crystal display system includes a data driver, a scan driver, a liquid-crystal panel, a line memory (204 in FIG. 2) in which input display data (101) for representing any of display-ON, display-OFF and halftone every pixel are stored for, at least, one line, and a halftone pattern generator (200) by which liquid-crystal display data (106) to be applied to the data driver are generated using the contents of the line memory and the input display data. The halftone pattern generator generates ON data in response to the input display data representing the display-ON of the pixel; it generates OFF data in response to the input display data representing the display-OFF of the pixel; and it generates the ON data and the OFF data alternately in successive frames as halftone data in response to the input display data representing the halftone display of the pixel, and it also compares the input display data of a pertinent line and those of a preceding line every line so as to invert a phase of changing-over the ON data and the OFF data in accordance with a result of the comparison. Since the number of ON pixels (or pixels for either of first and second data) for the halftone display is substantially equalized every frame, flickering can be reduced irrespective of display patterns.

    摘要: A display unit which can detect the X coordinate of a position with which a pen is in contact more efficiently. In a non-display period, X-electrodes are grouped into N regions according to the X-electrode arrangement, each region is divided into two parts according to the X-electrode arrangement, and selection voltage is applied to the X-electrodes belonging to each part having larger X coordinates. The process is repeated in order while N is doubled from one to the half value of the number of the X-electrodes of a liquid crystal panel. If a pen coming in contact with the liquid crystal panel and detecting X-electrode selection voltage detects selection voltage with respect to each N value, the Nth most significant bit of the X coordinate of the position with which the pen is in contact is set to `1.` If the pen does not detect selection voltage, the bit is set to `0.` Thus, the X-electrode of the position with which the pen is in contact can be detected at the number of selection voltage application times equal to the minimum number of bits that can represent each of the X-electrodes.
