OMAP-L137 Display Interface

Other Parts Discussed in Thread: OMAP-L137

Why doesn't the OMAP-L137 display interface support 18-bit LCDs?  It seems to me that this is the most common color depth on most small VGA displays... (ie 5.7")

    Likely becuase this part was not targeted at the broad video market; the strenghts is this part are its low power (video take more processing power and in turn power consumption) and it floating point capability (among other things).  These features make it ideal for high-end audio applications (floating-point) and hand-held industrial applications perhaps requring floating point accuracy with low-end display capabilities (QVGA, QCIF, or simpler)....

    We do have other parts targeted at the video market that can handle up to 24-bit video output data bus (enough for 24-bit RGB if necessary); as you may guess, with video application requiring more processing power, these parts comsume a bit more power than OMAP-L1.

    If you are not sold on OMAP-L1 yet and want advice on potential opions, feel free to describe your end-application and we will try pointing you in the right direction..

    Juan is right, the OMAP-L137 was never really targeting video applications that would use higher end LCDs, in the end it is a matter of lowering the cost of the device to cater to the intended audience (high end audio) as best as possible. At the moment there is not even a way to demo the LCD display as this was not originally thought to be a priority to the broad market, though I believe this is changing and there will be a daughterboard with LCD for the EVM from Spectrum Digital.
