Computer display driving system

摘要

An image display system includes an LCD (liquid crystal display) or other display driven by alternating current and driven in an inverted manner by a predetermined driving method on a pixel basis, and an LCD driving device for generating a Frame Rate Control (FRC) pattern which is the same as the pattern utilized by the predetermined driving method. The display is thereby driven so as to allow the display to make an expression in gradations higher (for example, 256 gradations) than gradations (for example, 64 gradations) natively supported by the display.

主权项

1. An apparatus for driving a computer system display at a first number of pixel gradations where the display supports a second number of gradations lower than the first number, the apparatus comprising:
pattern generating means for generating a Frame Rate Control (FRC) pattern by allocating, for each pixel, an A-th gradation and a B-th gradation, where A and B are sequential integers equal to or greater than zero and contained within the second number; and shifting means for shifting adjacent lines in different directions reverse to each other, the lines being lines of the FRC pattern generated by the pattern generating means.
