According to recent research from NHK and Sony, current high definition displays lack the capability to display fast moving images thus causing them to blur, but Field Emission Technologies is developing their nano-Spindt Field Emission Display (FED) monitors which is already equipped for the future of High Definition Images.

Blurred images are caused by two factors: the hold type drive system used by LCDs and PDPs and the responsiveness of liquid crystal elements in LCDs and decay characteristics of phosphors in PDPs. Nano-Spindt FEDs are the first flat panel monitors with high speed capability and never produce a blurred image thanks to the use of a line-sequential impulse drive system which has been tested at 240Hz and a newly developed phosphor with short decay time and a luminous efficacy higher than 25 percent. This new phosphor also contributes to the superior color reproduction and avoids the light leakage of LCDs and PDP's excessive emission to produce true black.

The FEDs combine the space saving and easy to use qualities of flat panel displays and the image quality of CRT monitors and is currently targeted for commercial work.
Unlike other flat panel displays, FEDs can provide equal brightness and color uniformity when viewed from all angles. They also have a gamma curve which is similar to broadcast signals thus allowing easy color matching.
