Patent ID: 7683878

Claim:
A system for providing dual resolution control of a display panel, said system comprising: a dual resolution control circuit comprising: first, second, third and fourth shift registers, each of the shift registers outputting a shifting signal; first, second, third and fourth logic gates; and a switching network, coupled among the shifting registers and the logic gates; wherein, in a low resolution mode, the switching network directs the shifting signals to the shift registers such that each of the first and the third shift registers outputs a first shifting signal and each of the second and the fourth shift registers outputs a second shifting signal, the switching network also directs the shifting signals to the logic gates such that each of the first and the second logic gates outputs a first panel control signal and each of the third and the fourth logic gates outputs a second panel control signal, and wherein pulses of the first and the second panel control signals do not overlap, wherein the phase of the shift signals of the first and the third shift registers are in-phase, the phase of the shift signals of the second and the fourth shift registers are in-phase, and wherein the first, the second, the third and the fourth shift registers are not cascaded successively.
