Abstract
The present invention relates to display adjustment and balance methods for liquid crystal displays, LCDs. A wide-range display position adjustment method is described. Compared with the prior art liquid crystal display controllers, the embodiments of this invention are not limited by the width of the vertical and horizontal front and back porch regions of the timing diagrams. These porch values are a function of the display chip technology. The display location control of this invention is independent of the limits of the front and back porch times. The embodiments of this invention facilitate the design of a display position control circuit which allows the image display to be rolled around anywhere on the panel.
