a liquid crystal display system which can accept input display data having a resolution which is larger or smaller than a resolution of a liquid crystal panel , 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 .
