Abstract
In one embodiment, a driving method for a liquid crystal display device having a backlight is provided. Input digital video data is analyzed and an adaptive brightness control signal is generated based on a brightness analysis of the input digital video data. An external brightness control signal is received via a user interface. A plurality of brightness control voltages is generated based on the adaptive brightness control signal. The plurality of brightness control voltages represents different brightness levels. One of the brightness control voltages is selected in response to the external brightness control signal. The backlight operates according to the selected brightness control voltage.
