发明名称 CIRCUITRY FOR INDEPENDENT GAMMA ADJUSTMENT POINTS
摘要 A display architecture providing independent adjustment of gamma with respect to each color channel of a display is provided. In one embodiment, gamma adjustment circuitry may utilize separate resistor strings for each color channel of the display. Gamma adjustment voltage taps for each resistor string may each be coupled to a respective switching logic block that includes a plurality of switches, each of which may be coupled to different respective locations of the resistor string. Based upon a gamma correction profile defining optimal gamma adjustment points for a particular color channel based at least partially upon its transmittance sensitivity characteristics, appropriate control signals may be provided to each of the switching logic blocks to facilitate the connection of the gamma adjustment voltage taps to desired adjustment points on a respective resistor string in order to optimize gamma correction and provide for increased accuracy in color output.
