Abstract
A gamma correction method adapted for a liquid crystal display panel is provided. The gamma correction method includes the following steps. A reference gamma curve is provided. The LCD panel is lighted up with at least one of primary-color frames. Gamma voltages of the primary-color frame are set for the LCD panel based on the reference gamma curve to obtain at least one primary-color gamma curve. The gamma correction is performed on the LCD panel based on the at least one primary-color gamma curve or a linear combination curve of the at least one primary-color gamma curve. By using the gamma correction method, the LCD panel could be allowed to provide good image quality.
