    In looking at the Sharp LH7400 User Guide, they only talk about bit-per-pixel modes 1, 2, 4,8 & 16 for the Color LCD Controller. I am assuming that this means that the on-board LCD controller cannot do more than 16 bpp. Is this correct?

    If you need to do greater than 16 bpp, what are the options? Do you need to bypass the on-board LCD controller and use an external controller chip to get better than 16 bpp?

    Thanks for the info in advance,
    Frank

    I realize this is an older post, but I thought I should get a response in.

    The LH7A400 internal LCD controller will support up to 16bpp, without any external hardware. If a bpp value greater of 16 is needed, it is recommened to use an external graphics controller.

    Logic has worked with customers to implement several different external controllers. Please contact the support team for design considerations.
