Question about LCD-TFT controller

imarz.1
Associate III

I am new to STM32H7xx, and in the datasheet of these microcontrollers I read:

"...The LCD-TFT display controller provides a 24-bit parallel digital RGB (Red, Green, Blue) and delivers all signals to interface directly to a broad range of LCD and TFT panels up to XGA (1024x768) resolution..."

My question is: What do they mean by "TFT panels up to XGA (1024x768) resolution" ?

Do they mean the controller also has an internal framebuffer ? Or is it just a controller without framebuffer, and I need to provide the framebuffer ?

For 24-bit, XGA (1024x768) resolution, the framebuffer needs to be around 2.4Mbyte.

Thanks.

Closer to 19Mbit, 2.25 MByte

For parts without that much internal contiguous RAM, the expectation would be a frame buffer, or buffers, in SDRAM, the goal here being to drive it directly with the STM32 without involving a display with it's own controller/frame-buffer, in which case you'd typically have that hung off the FMC
