Besides, the LED driver with brightness control and the driving method thereof do not require that an operator adjusts the variation of the LED current in different operating current ranges in advance, thereby reducing the test time and cost and avoiding the operator from deciding a wrong ...
If an integrated display is detected, Windows will query the WDDM driver for the DXGK_BRIGHTNESS_INTERFACE_2 interface. This interface is mandatory for all WDDM 1.2 drivers. The presence of this interface indicates that the driver supports brightness control of the integrated display....
