Staggered line inversion and power reduction system and method for LCD panels
Abstract:
Systems and methods are disclosed for various inversion techniques for an LCD array, such as a staggered 2-line inversion, a staggered 1-line inversion, or a staggered N-line inversion. The staggered inversion may invert 2-lines, 1-line or N-lines of an array over the duration of a frame displayed on the array. Additional systems and methods may include a high impedance power reduction technique that may be applied alone or in combination with the various inversion techniques. Specifically, electrode drivers for “idle” lines of a staggered 1-line, 2-line, or N-line inversion may be switched to a high impedance state such that the corresponding drivers for the idle lines use reduced power during the inversion of the “active” lines.
