Abstract
Method and apparatus for mode switching are provided in the disclosure. Aspects of the disclosure provide a method for switching a display mode of a device. The method includes receiving an intensity value of ambient light when the device is in a first control mode in which backlights of a liquid crystal display screen are controlled in order to control a display brightness of the liquid crystal display screen, determining whether the intensity value is less than a predetermined threshold, and when the intensity value is less than the predetermined threshold, controlling the device to enter a second control mode in which voltages provided to data lines of the liquid crystal display screen are scaled according to a ratio in order to control the display brightness of the liquid crystal display screen.
