Good afternoon,
We have a client that has implemented our i.MX 6DualPlus-based SOM on their product. Their user interface requires the use of an 1920x1200 LCD display connected to the SOM via a parallel 24-bit display port. So far this implementation is working correctly, but now they are looking to create an alternative version of this product using our i.MX 6DualLite-based SOM instead of the 6DualPlus, but they're not sure if that SOC supports the resolution of their LCD display. We currently don't have the hardware necessary to test this for ourselves, so it would be great to get an official statement on this.
According to the i.MX6/i.MX7 family comparison table, the maximum LCD display resolution supported by the 6DualLite is 1280x720: https://www.nxp.com/docs/en/brochure/FLYRIMXPRDCMPR.pdf
However, a colleague of mine found the following text in the i.MX 6Solo/6/DualLite Applications Processor Reference Manual (page 203):
Each i.MX 6Solo/6DualLite processor enables the following interfaces to external
devices (some of them are muxed and not available simultaneously):
• Displays—Total four interfaces available. Total raw pixel rate of all interfaces is up
to 266 Mpixels/sec, 24 bpp. Up to three interfaces may be active in parallel
(excluding EPDC).
• One Parallel 24-bit display port, up to 225 Mpixels/sec (for example, WUXGA at 60
Hz or dual HD1080 and WXGA at 60 Hz)
• LVDS serial ports—One port up to 170 Mpixels/sec or two ports up to 85 MP/sec
(for example, WUXGA at 60 Hz) each
• HDMI 1.4 port
• MIPI/DSI, two lanes at 1 Gbps
• EPDC, Color, and monochrome E-INK, up to 1650x2332 resolution and 5-bit
grayscale
It mentions that the 24-bit parallel display port could support WUXGA, but I assume this is just an example of a mode that can be achieved with the interface's bitrate, rather than an actual mode that is supported by the SOC.
In short: is the i.MX 6DualLite capable of using a resolution of 1920x1200 for an LCD display via a 24-bit parallel port?
Many thanks in advance and best regards,
Gabriel
