BACKLIGHT DRIVING CIRCUIT, DRIVING METHOD AND BACKLIGHT MODULE

摘要

A backlight driving circuit is disclosed. The backlight driving circuit includes a temperature sensing module, a comparing module and a backlight driving module. The temperature sensing module is for monitoring a temperature of different areas of a loading and is for outputting a plurality of sensing signals. The comparing module is for comparing the plurality of sensing signals generated from the temperature sensing module and for outputting control signals. The control signals are for controlling an amount of the driving current outputted from the backlight module. The backlight driving module is for converting an input voltage to a needed driving current and for providing the driving current to the loading. By configuring the temperature sensing module in the proximity of the backlight source, the backlight driving circuit monitors the working temperature of different areas of the backlight source and provides the working temperature to the backlight driving module.
