| 摘要 |
A processing circuit coupled to a controlling circuit and including a first capacitor module, a second capacitor, a detection module, a first processing module, and a second processing module is disclosed. The first and the second capacitor modules are charged. The detection module generates a detection signal according to intensity of a light to charge the first and the second capacitor modules. The first processing module asserts a first output signal according to the time of charging the first capacitor module. The second processing module asserts a second output signal according to the time of charging the second capacitor module. The controlling circuit controls a backlight according to the asserted output signal.
