LCD framebuffer driver

Hi All,

I want to write/test a basic framebuffer based driver for LCD on Beaglebone black
having an SPI interface.
My question is

1> which LCD should I order? I think I should order the LCD whose driver already there in the kernel, am I right? but which one.

2> Any TFT or STN LCD, please let me know. How I go about it, I basically want to
change some parameters and experiment and test…
I do not have a monitor
