摘要:
The initial color temperature setting can change when a plasma display panel (PDP) is driven for a long period of time. One cause is due to the non-uniform deterioration of red, green, and blue fluorescent materials due to the ultraviolet rays discharged during operation of the panel. Color temperature correction is performed by setting the numbers of discharge pulses for fluorescent materials in accordance with a discharge pulse number correction curve with respect to the cumulative elapsed driven time of the PDP.
