Aside from the cool techy factor, the reasoning behind these devices is much reduced eye strain and headaches. Originally they tried using white or blue leds and this helped but it washed out the picture, enter some genius that color matched the bleeding edges. Another benefit from these leds is the perception of a 5-10 inch larger screen.

It really is a neat concept and can be done with a raspberry pi, rgb led strips and some 7th grade level soldering. If you aren't up for spending large sums of cash and are in need of a fun weekend project.
