What is the resolution of MCIMX28LCD module?

[chunei]

I bought this module and could never find what is the resolution. There is place show WVGA that means 800*480 or 854*480. I also saw WQVGA and I assume it means 480*272 or xxx.

Does anyone know its resolution?

Thanks,

Chu

Hi Chu

Yes this is correct (as mentioned in RM and linux sources),

that the i.MX28 is able to drive LCD panel up to 800x480

resolution at 60Hz. Since both pixel pipeline and LCDIF do not impose any hard

maximum limit to 800x480, in general higher resolution LCD panel is allowed.

However, we do not recommend driving any panel with higher resolution than

800x480 due to limited internal bus bandwidth. In theory it is possible to run at a

higher resolution at lower frame rate (800x600 @ 48Hz is the same number of

pixels/sec as 800x480 @ 60Hz).

Best regards
