eDP Connector
SC61 offers, as a factory alternative to LVDS interface,
a dedicated embedded Display Port interface, which
is obtained by using a DSI-to-eDP bridge type TI
SN65DSI86. Maximum supported resolution is
1920x1200 @ 60Hz.
For the connection of this kind of displays, on-board there is a VESA
®
certified connectors for
embedded Display Port interface, type STARCONN p/n 300E40-0110RA-G3 or equivalent
(microcoaxial cable connector, 0.5mm pitch, 40 positions).
BKLT_PWR and LCD_PWR values can be set by using dedicated jumpers CN34 and CN35,
as described in the previous paragraph 3.3.4.
Here following the signals involved in eDP management:
eDP_ML0P/eDP_ML0N: embedded DP differential data pair #0.
eDP_ML3P/eDP_ML1N: embedded DP differential data pair #1.
eDP_ML3P/eDP_ML2N: embedded DP differential data pair #2.
eDP_ML3P/eDP_ML3N: embedded DP differential data pair #3.
eDP_AUX_P/eDP_AUX_N: embedded DP auxiliary channel differential data pair.
BKLT_EN: LCD_PWR electrical level Output with a 10k
Ω
pull-up resistor, Backlight Enable
signal. It can be used to turn On/Off the backlight
’
s lamps of connected displays.
BKLT_PWM: this signal can be used to adjust the backlight brightness in displays supporting
Pulse Width Modulated (PWM) regulations (LCD_PWR electrical level).
