Embedded DisplayPort* (eDP*) Backlight Control Signals

Signal Name Type Description
VDDEN O Primary eDP Panel power Enable : Panel power control enable. This signal is used to control the VDC source of the panel logic.
eDP_​BKLTCTL O Primary eDP Backlight Enable : Panel backlight enable control for eDP This signal is used to gate power into the backlight circuitry.
eDP_​BKLTEN O Primary eDP Panel Backlight Brightness control : Panel brightness control for eDP. This signal `is used as the PWM Clock input signal.
GPP_​A17/DISP_​MISCC O Secondary eDP Panel power Enable : Panel power control enable. This signal is used to control the VDC source of the panel logic.
GPP_​A21/DDPC_​CTRLCLK O Secondary eDP Backlight Enable : Panel backlight enable control for eDP This signal is used to gate power into the backlight circuitry.
GPP_​A22/DDPC_​CTRLDATA O Secondary eDP Panel Backlight Brightness control : Panel brightness control for eDP. This signal `is used as the PWM Clock input signal.
Note:VDDEN, eDP_​BKLTEN, eDP_​BKLTCTL, DISP_​MISCC, DDPC_​CTRLCLK, DDPC_​CTRLDATA can be left as no connect if eDP* is not used.
