Method for adjusting gamma curve and gamma voltage generator and display control system therof |
摘要 |
A method for adjusting a gamma curve used in a display control system of a display apparatus, and the method comprises steps of: analyzing each sub pixel gray value distribution of each color in a frame; and adjusting at least a gamma reference voltage according to the sub pixel gray value distribution of the color, such that a gray level voltage number corresponding to the sub pixel gray values in at least a predetermine region which has the relative large statistical number or ratio is increased, and a gray level voltage number corresponding to the sub pixel gray values in at least a predetermine region which has the relative low statistical number or ratio is decreased. |

1. A method for adjusting a gamma curve for a display control system of a display apparatus, comprising:
analyzing a pixel gray value distribution of each frame and a sub-pixel gray value distribution of each of a plurality colors; and dynamically adjusting at least a gamma reference voltage, a curvature and a function according to the pixel gray value distribution and the sub-pixel gray value distribution of each color, for increasing a gray level voltage number corresponding to pluralities of pixel gray values and sub-pixel gray values in at least a predetermined region which has a relatively larger statistical number or a relatively higher ratio, and decreasing a gray level voltage number corresponding to pluralities of pixel gray values and sub-pixel gray values in at least a predetermined region which has a relatively smaller statistical number or a relatively lower ratio. |
