Abstract
A liquid crystal display (LCD) system comprising: an LCD panel having a plurality of pixels arranged in an array having a plurality of columns and a plurality of rows; a sensor configured to detect a position of an observer in relation to the LCD panel; pixel control circuitry configured supply electrical signals to drive the plurality of pixels; and gamma correction circuitry associated with the pixel control circuitry, the gamma correction circuitry configured to implement gamma correction upon the electrical signals that drive the plurality of pixels that is based on a detected position of the observer with relation to the LCD panel. Associated methods are also described.
