摘要： A liquid crystal display system which can accept input display data having a resolution which is larger (e.g. 1120×780 dots) or smaller (e.g. 640×480 dots) than a resolution of a liquid crystal panel (e.g. 1024×768 dots), and convert the input display data to reduced or enlarged display data for display on the liquid crystal panel. The system generates, for example, one new vertical or horizontal line based on two contiguous vertical or horizontal lines in the input display data. If the resolution of the input display data is larger than the resolution of the liquid crystal panel, the system replaces the two contiguous lines with the one new line. If the resolution of the input display data is smaller than the resolution of the liquid crystal panel, the system inserts the one new line between the two contiguous lines.

摘要： A liquid crystal display system which can accept display data having a resolution different from that of a screen for the liquid crystal display and display the display data. For example, a CPU outputs display data of 1120.times.780 dots and a liquid crystal panel has a 1024.times.768-dot resolution which is smaller than the display data resolution. The display screen of the liquid crystal panel comprises a linear arrangement of pixels. A data conversion section generates display data for a new horizontal or vertical line based on display data for two horizontal or vertical lines contiguous to each other and repeats replacement of display data of the two lines with the display data of the one line for reducing the number of horizontal lines of one screen and the number of dots of one line so as to match the resolution of the display data output by the CPU with the liquid crystal display. In contrast, if the resolution of the display data is smaller than the screen resolution of the liquid crystal panel, the data conversion section inserts the display data of the new one horizontal or vertical line between the two contiguous lines for enlarging the resolution of the display data.

摘要： The invention is concerned with a liquid crystal display apparatus which displays data by driving a liquid crystal panel in synchronism with horizontal synchronizing signals and vertical synchronizing signals. The driver for driving the liquid crystal panel is provided with timing signals maintaining a predetermined period, and with a voltage in synchronism therewith, irrespective of the horizontal and vertical synchronizing signals. Therefore, even when the horizontal and vertical synchronizing signals have not been applied, the liquid crystal panel is provided with an a-c voltage of which the polarity is alternatingly reversed by the timing signals. Therefore, electrolysis does not take place in the liquid crystal panel, and the quality of display is not degraded.
