| 摘要 |
The present invention relates to an LCD technology. A circuit used for correcting a shift of the gamma curve because of light emitting diode (LED) temperature rise and a device thereof are proposed. The circuit includes at least one temperature sense resistor, an analog-to-digital converter (ADC), and a lookup table. One end of the temperature sense resistor is connected to the ADC which is connected to the lookup table. The present invention can improve image quality rapidly. The structure of the circuit proposed by the present invention is simple, making it easy to be performed, which is good for energy saving and environmental protection.
