LVDS Flat Panel signals
Embedded into NXP i.MX6 processor there is an LVDS Display Bridge, connected to the Image Processing Unit (IPU), that makes externally available two LVDS
channels, each one consisting of 1 clock pair and four data pairs.
It is possible to configure LVDS output so that it can be used as:
One single channel (18 or 24 bit) output, max resolution supported 1366 x 768 @ 60fps
One dual channel (18 or 24 bit) output, max resolution supported 1600 x 1200 @ 60fps
Two identical single channel outputs, max resolution supported 1366 x 768 @ 60fps
Two independent single channel outputs, max resolution supported 1366 x 768 @ 60fps on each channel
All of these possibilities come by opportunely configuring the O.S. installed on the module.
Here following the signals related to LVDS management:
/LVDS_A0-: LVDS Channel #0 differential data pair #0.
/LVDS_A1-: LVDS Channel #0 differential data pair #1.
/LVDS_A2-: LVDS Channel #0 differential data pair #2.
/LVDS_A3-: LVDS Channel #0 differential data pair #3.
LVD/LVDS_A_CLK-: LVDS Channel #0 differential Clock.
/LVDS_B0-: LVDS Channel #1 differential data pair #0.
/LVDS_B1-: LVDS Channel #1 differential data pair #1.
/LVDS_B2-: LVDS Channel #1 differential data pair #2.
/LVDS_B3-: LVDS Channel #1 differential data pair #3.
LVD/LVDS_B_CLK-: LVDS Channel #1 differential Clock
LVDS_PPEN: +3.3V_S electrical level Output, Panel Power Enable signal. It can be used to turn On/Off the connected LVDS display. This pin can also be used as
a Generic I/O pin, please check pin muxing table.
LVDS_BLEN: +3.3V_S electrical level Output, Panel Backlight Enable signal. It can be used to turn On/Off the backlight
’
s lamps of connected LVDS display. This
pin can also be used as a Generic I/O pin, please check pin muxing table.
LVDS_BLT_CTRL/GP_PWM_OUT0: this signal can be used to adjust the panel backlight brightness in displays supporting Pulse Width Modulated (PWM)
regulations. This pin can also be used differently, please check the pin-muxing table.
