LCD HEATING CONTROL SYSTEM AND METHOD THEREOF

摘要

A LCD heating control system and method enable a backlight module in a LCD to heat a LCD panel in the LCD. The LCD heating control system includes a heat-conducting element and a micro control temperature sensing circuit. The micro control temperature sensing circuit determines whether the sensed LCD temperature meets a heating requirement and, when the determination is affirmative, enables the backlight module to operate at a high power mode and heat to be transferred from the backlight module to the LCD panel through the heat-conducting element.

主权项

1. A LCD heating control system, adapted to control a backlight module in a LCD and thereby heat a LCD panel in the LCD, the LCD heating control system comprising:
a heat-conducting element for connecting the LCD panel and the backlight module so as to transfer heat from the backlight module to the LCD panel; and a micro control temperature sensing circuit disposed in the LCD to sense a temperature of the LCD, enable the backlight module to operate at a high power mode when the sensed temperature meets a predetermined heating requirement, and enable the backlight module to operate at a low power mode having a power lower than the high power mode when the sensed temperature does not meet the heating requirement.
