Things have picked up a bit since Sutherland. An LCD or DMD or OLED
has logic in it, there's soon no longer need to render stuff from
framebuffer: framebuffer could render itself. You can already have that, if
you consider a DMD as a SRAM. You could render very well via PWM, synching
RGB LED flashes with block copies.
I think this will happen first with OLED displays, because here each bit can
drive a primary color. But with semiconductors you can put 3d acceleration
onboard, and directly talk to the display via a high-speed connection.
