Wondering... I searched many in the internet as I can and not find...

I was asking why do the TFT LCD need SD?

  • Can without use SD?
  • Can use memory like RAM chip? because faster? if no because need SPI?

Thanks.

TFT LCD doesn't need SD. You probably saw a TFT LCD module with embedded system. Usually, the SD card is used for holding picture.
