Abstract:
1. An overvoltage protection method for backlight drive circuit of 2D/3D mode, comprising the following steps: (1) providing a liquid crystal display, the liquid crystal display having a 2D mode and a 3D mode, the liquid crystal display comprising a backlight drive circuit; (2) the backlight drive circuit using the first overvoltage protection voltage level as an overvoltage protection voltage level when the liquid crystal display is set in the 2D mode; and (3) the backlight drive circuit using the second the overvoltage protection voltage level as an overvoltage protection voltage level when the liquid crystal display is set in the 3D mode, the second the overvoltage protection voltage level being greater than the first overvoltage protection voltage level.
