BB-View 7" LCD is NOT 24 Bit!!

qmiteam

 

Hi we are using the Beaglebone Black 7" BB-View LCD Package and it is advertised as a 24 bit LCD. According to the Innolux datasheet for the LCD on your website (AT070TN83) and the wiring on the LCD carrier board, it is only an 18 bit display. Please explain.

    well, what's the difference ? you will not be able to say if it's running RGB565, RGB666 or RGB888. also RGB888 will work with RGB666, you just get spare wires.

     

    Many times in advertisement they declare default things (like lcd is 24b) , but in reality they are not. i would be mad if resolution is different or screen is NT panel instead of IPS, but rgb format width  for me is not that important (if it goes over 16b, i am good)

    The difference is I paid for 16.8M colors, not 65k.  The stock original circuitco designed LCD and associated BSP's from Angstrom were all 16Bit RGB565 driving 18bit LCD's.  The BB-View and associated "special" BSP's are configured for RGB888, but the LCD and carrier board is only RGB666.  The reason we are developing on a 24 bit platform is due to not getting smooth gradients with 16/18bit, so we ordered this BB-View as it is clearly advertised as a 24Bit solution, but in fact it is not.
