GAMMA CURVE ADJUSTMENT METHOD AND GAMMA CURVE ADJUSTMENT APPARATUS |
摘要 |
A Gamma curve adjustment method and a Gamma curve adjustment apparatus for a display apparatus. The method includes: obtaining correspondence relationship between current grayscale voltages and first transmittances of the display apparatus, the first transmittances being the transmittances of the display apparatus driving by the current grayscale voltages; determining a target grayscale voltage corresponding to each gray scale based on the correspondence relationship between the current grayscale voltages and the first transmittances and an ideal Gamma curve; generating and outputting the target grayscale voltage corresponding to each gray scale to the display apparatus; and obtaining an actual Gamma curve of the display apparatus driven by the target grayscale voltages as a final Gamma curve. The Gamma curve adjustment method improves the speed and efficiency of adjusting the Gamma curve. |
