Patent ID: 8427414

Claim:
A method comprising: adjusting in a liquid crystal display a second voltage relative to a first voltage, the liquid crystal display comprising a liquid crystal layer and a common electrode, the liquid crystal layer having a first side and an opposing second side, the common electrode disposed on the first side of the liquid crystal layer, the common electrode arranged to receive a common voltage, wherein the liquid crystal display comprises a plurality of pixels and at least some of the pixels comprise a first area and a second area, the first area comprising a first electrode disposed on the second side of the liquid crystal layer, the second area comprising a second electrode disposed on the second side of the liquid crystal layer adjacent to the first electrode, wherein the first electrode is arranged to receive the first voltage to achieve a first optical transmissivity through the liquid crystal layer in the first area in response to the first voltage, and the second electrode is arranged to receive the second voltage to achieve a second optical transmissivity through the second area in response to the second voltage, wherein the first optical transmissivity comprises a lower transmissivity curve section and a higher transmissivity curve section and the second optical transmissivity comprises a lower transmissivity curve section and a higher transmissivity curve section, and wherein the second voltage is adjusted for substantially matching the higher transmissivity curve section of the second optical transmissivity to the higher transmissivity curve section of the first optical transmissivity, leaving a discrepancy between the lower transmissivity curve section of the second optical transmissivity and the lower transmissivity curve section of the first optical transmissivity; and providing a third voltage different from the common voltage to the second electrode via a charge storage device so as to reduce the discrepancy between the lower transmissivity curve section of the second optical transmissivity and the lower transmissivity curve section of the first optical transmissivity.
