DM365 LCD Interface

Niranjan Gupta

Hi, 

We are using a leopard board from leopardimaging based on DM365. We would like it to display images on an LCD. The board has a 50 pin connector for LCD interface. The specification says its a 16-bit LCD interface (which I assume is 565). Can I hook it with a 18-bit LCD?  In particular I am considering Sharp LCD LQ043T3DX02. 

Please let me know if this LCD will be compatible with DM365 LCD output?

 

Thanks, 

Niranjan

    Niranjan,

    You can connect the 16 bit output from DM365 to an 18 bit (or higher) LCD by ensuring that you connect the highest data bits from each source color channel to the highest data bits of the corresponding LCD color channels.

    Any unused data inputs to the LCD can either be connected to '0', to '1' or to MSBs of their respective color outputs.

    Connecting to '0' means that you can truly achieve black, but will not be able to achieve truly full white.

    Connecting to '1' means that you can truly achieve white, but will not be able to achieve truly full black.

    Connecting to the MSB of the corresponding color channel means you can truly achieve full white and full black but there will be a very slight non-linearity in the color in the mid point.

    BR,
