Method of storing gamma data in a display device, display device and method of operating a display device

摘要

A method of storing gamma data in a display device is disclosed. First, a plurality of gamma curves for a plurality of pixels are provided. One of the plurality of gamma curves is stored as a reference gamma curve in a gamma table included in the display device. Among a plurality of gray levels, a portion of the plurality of gray levels are selected according to a gamma curve characteristic of the display device. With respect to at least one gamma curve of the plurality of gamma curves, differences between the at least one gamma curve and the reference gamma curve at the selected portion of the plurality of gray levels are stored in the gamma table.

1. A method of operating a display device, the method comprising:
providing a plurality of gamma curves for a plurality of pixels; storing one of the gamma curves as a reference gamma curve in a gamma table included in the display device; selecting, among a plurality of gray levels, a portion of the gray levels for storing offset data from the reference gamma curve, the portion of gray levels selected corresponding to inflection points of a gamma curve characteristic of the display device; with respect to at least one of the gamma curves, storing differences between the at least one gamma curve and the reference gamma curve at the selected portion of gray levels in the gamma table; and driving the plurality of pixels based on the stored difference.
