Hi min

in general i.MX6Q has 2 IPU modules and 2 display panel via 24bpp RGB LCD can

be supported, provided there are external signals for these interfaces, please check

Table 4-1. Pin Assignments i.MX6DQ Reference Manual
https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf

May be useful to use PINS-TOOL :

Pins Tool for i.MX Application Processors|NXP

2 lvds also supported according to Table 39-3. LDB External Signals.

Best regards
igor
