Abstract
The present disclosure discloses a backlight control circuit for adjusting a current of an LED module of an electronic device including a driving chip having a feedback terminal and a reference voltage terminal, a feedback voltage regulating unit, and a power supply regulating unit; the feedback voltage regulating unit is also connected to the 2D/3D signal terminal, the feedback terminal voltage is controlled so that the feedback terminal voltage of the feedback terminal of the driving chip is lower than the reference voltage of the reference voltage terminal when receiving the three-dimensional signal generated at the 2D/3D signal terminal. The present application also provides an electronic device. With the scheme of the present application, the current of the LED module can be increased when the electronic device is in the three-dimensional mode.
