Abstract
A method is provided for adjusting color temperature in a PDP device. The method includes setting a desired color temperature of the PDP as the RGB ratio which shows the level ratio of each of the RGB signals, setting each light emitting frequency of the PDP corresponding to the level of each of the A/D converted RGB signals, and selecting a subfield of gradation frequency corresponding to the set light emitting frequency to control the light emitting of the PDP. According to the method, the color temperature can be adjusted without lowering the gradation in the PDP.
