e/ eDP0_AUX-: embedded DisplayPort Channel #0 auxiliary channel
The signals for secondary channel are LVDS:
/ LVDS_B0- : LVDS Channel #B differential data pair #0
/ LVDS_B1-: LVDS Channel #B differential data pair #1
/LVDS_B2-: LVDS Channel #B differential data pair #2
/ LVDS_B3-: LVDS Channel #B differential data pair #3
LVD / LVDS_B_CLK-: LVDS Channel #B differential Clock
In addition, the following control signals are present:
LVDS_PPEN: +3.3V_RUN electrical level Output, Panel Power Enable signal. It can be used to turn On/Off the connected display.
LVDS_BLEN: +3.3V_RUN electrical level Output, Panel Backlight Enable signal. It can be used to turn On/Off the backlight s lamps of connected display.
LVDS_BLT_CTRL: this signal can be used to adjust the panel backlight brightness in displays supporting Pulse Width Modulated (PWM) regulations.
LVDS_DID_DAT: LCD I2C Data. This signal is used to read the LCD display EDID EEPROM. +3.3V_RUN electrical level Bidirectional
LVDS_DID_CLK: LCD I2C Clock: This signal is used to read the LCD display EDID EEPROM. +3.3V_RUN electrical level Output
compatible LVDS output bridge, connected from one channel of the four-lane MIPI-DSI of the
processor to the LVDS Channel #A and #B interfaces of the edge connector.
As a factory alternative, the module has a Texas Instrument
bridge, connected from one channel of the four-lane MIPI display serial
interface to eDP0 interface of the edge connector.

HDMI interface signals
The NXP i.MX 8M processor has an HD Display Transmitter Controller (HDMI TX), which offers multi-protocol support of standards such as HDMI, DisplayPort, eDP,
with one of these standards supported at a time. In case HDMI is selected, it provides an HDMI standard interface for HDMI 2.0a compliant displays. Supports HDCP
2.2 and HDCP 1.4
The signals are:
TMD / TMDS_LANE0-: HDMI Output Differential Pair #0
TMD / TMDS_LANE1-: HDMI Output Differential Pair #1
TMD / TMDS_LANE2-: HDMI Output Differential Pair #2
T / TMDS_CLK-: HDMI Differential Clock
