The invention discloses a method and device for adjusting
gray level transition and color of a
display device. The method includes the steps that when any debugging
gray level is adjusted, preferably, the target
chromaticity brightness, a target brightness coefficient group, the current brightness
chromaticity and a current brightness coefficient group which correspond to the debugging
gray level are acquired, an adjustment relative brightness group is calculated according to a current relative brightness group, the target brightness coefficient group and the current brightness coefficient group which correspond to the current
chromaticity brightness, a preset
database is searched so that a target set value group corresponding to the target relative brightness can be determined, the debugging gray level is adjusted through the target set value group, and therefore the purpose for adjusting gray level transition and color of the
display device is achieved. The technical scheme does not need to be manually adjusted and production efficiency is improved; in addition, the preset
database is searched so that the target set value group can be determined, time spent in adjusting gray level transition and color of the
display device is further shortened, and production efficiency is improved.
