ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD FOR SETTING GAMMA REFERENCE VOLTAGE THEREOF |
| 摘要 |
An organic light emitting display device includes a gamma reference voltage setter to set a gamma reference voltage, a gamma reference voltage generator to generate a gamma reference voltage set by the gamma reference voltage setter, and a gamma voltage generator to generate a gamma voltage based on the gamma reference voltage. The gamma reference voltage setter sets the gamma reference voltage to a first temporary value, increases the first temporary value by a first delta value, searches a second temporary value at which luminance of the display panel is less than a preset value, and sets the gamma reference voltage based on the searched second temporary value. |

1. A method for setting a gamma reference voltage of an organic light emitting display device, the method comprising:
setting the gamma reference voltage to a first temporary value; searching a second temporary value while increasing the first temporary value by a first delta value, the second temporary value corresponding to a value at which luminance of the organic light emitting display device is less than a preset value; and setting the gamma reference voltage based on the searched second temporary value. |
