This LCD has indeed build-in SD card reader which I wanted partially use to store images, partially to permanent store data collected by arduino.
I would prefer to use SPI (so I will have more pins available for other extensions) but I also want LCD to refresh with decent speed, to not get some flickering images.
As for LCD manufacturer it is hard to determine but I can tell you few details of it:
LCD controller is LGDP 4531
Touch Screen controller ADS7843
Built-in SD card socket.
There is also place for AT45DBxxx memory, but I do not plan to use it in near future (instead I want to attach EEPROM to I2C bus with some other parts).
I don’t know if this is necessary but If you want to see it, here is some pics:
In this project arduino will have to collect some data form ‘external sources’ and then store data to SD card and display information about gathered data to LCD.
