| 发明名称 | Gamma correction system and method for display device | ||
| 摘要 | A gamma correction system and method for a display device are disclosed. According to one aspect, the gamma correction system includes a display panel configured to display an image, a measuring unit configured to acquire optical characteristic information from the image displayed on the display panel, and a display panel driver configured to convert a gamma data result value obtained after performing optical compensation for at least two sample gray values among a plurality of reference luminance values into a corresponding data voltage and calculate a data voltage for the rest of the luminance values for which optical compensation is not performed. | ||

| 主权项 | 1. A gamma correction system for a display device, comprising: a display panel configured to display an image; a measuring unit configured to acquire optical characteristic information from the image displayed on the display panel; and a display panel driver configured to convert a gamma data result value obtained after performing optical compensation for at least two sample gray values among a plurality of reference luminance values into a corresponding data voltage and calculate a data voltage for the rest of the luminance values for which optical compensation is not performed; wherein the optical compensation compensates deviation from standard target values of luminance, a color coordinate, and a gamma curve corresponding to the sample gray value for the displayed image on the display panel. | ||
