20120281008 | COLOR CORRECTION METHOD AND APPARATUS FOR DISPLAYS - Method and apparatus for adjusting the display characteristics of an electronic display, such as a computer or television display. The display is color corrected, e.g., at the factory, to measure its white point correction, gamma and gray tracking correction, and the gain correction over time as the display warms up. Moreover the white point correction and the gamma correction are performed on a per unit basis for each individual display to be manufactured. The resulting correction parameters are stored in memory or firmware associated with the display. Thereby when the display is in use, it performs compensation for white point, gray tracking and gain correction as the display warms up, each time it is powered up or when its thermal operation conditions change. | 11-08-2012 |
