Need a ready to use SPI controlled LCD or TFT display 800x480 or a little less..

I have a new PIC project coming up..
An electronic calendar...
This project would use some kind of display that would
show a complete calendar page on the screen (very static, no speed code)
with a grid of 7 columns and 7 rows showing all the days of the month
with one highlighted (today).
To do so I need a display that would do 800x480 (or less if necessary)
and that would be controlled by SPI and a PIC micro.
The PIC does not need to be fast at all since the display
will update only once a day !
I've seen many displays on sale at eBay like this one:
https://ebay.us/mEIM73
But they sometimes seem to need a kind of 'controller board' with memory
to be paralell controlled or by SPI in my case.
So I need your help to find a 'ready to use' display
that would do 800x480 or a little less with SPI control.
Waiting your reply..

    Maybe you could google "spi lcd graphic panel 800 x 480"

    >Maybe you could google "spi lcd graphic panel 800 x 480"
    I already did that since yesterday...
    The large graphic display world is kind of unclear to me sorry..
    I'm used with small LCD display like 16X2 or 32X4..
    Again this display could do
    https://ebay.us/mEIM73
    but there is a lack of information,
    or the specs are hard to understand..
    Still searching..

    so you are all set then
    you found an SPI Lcd and they tell you which controller is used
    download the controller documentation and start coding.

    Yeah, the controller (chip ??) is a FTDI FT810 and I have the documentation
    but these 'on sale' displays do not show details about their connectors
    and way to interconnect to outside world (paralell or SPI).
    That is why this topic. I need a 'hardware specs detailed' display.

    maybe you could ask the supplier for the mating connector details for his display ?

    For Chinese Screen manufacturers you can almost never get datasheet (at least in English) all you do is look at what the controller chip is.
     
    For https://ebay.us/mEIM73
    The controller is FT810 Embedded Video Engine
    This is the datasheet
    https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT81x.pdf
     
    That one is fairly straight forward to drive

    For that sort of application, you're probably better off looking at an "e-Paper" display.
    e.g. https://www.ebay.com/itm/4-2inch-e-Paper-Module-for-Raspberry-Pi-400x300-E-lnk-Display-SPI-2-Grey-level/26315323009
