There are already a few television display on the market with a 4k resolution (8 Mpixels). That is 4 times the resolution of present HDTV. The problem in increasing the screen resolution is that pixels have to become smaller and by getting smaller they lose brightness.
Now Samsung has shown a prototype of 4k screen using a new electronic backplane based on metal oxide semiconductors, improving on the performances of today’s amorphous silicon. The increase in performances does not correspond to an increase in price making this new technology particularly attractive.
Ultra definition television, with screen matching our eye resolution are getting nearer to our homes. Just wait a bit more for them and for the fiber to provide the required bandwidth.
