The next phase in display technology will hit the market soon. Sony recently showcased a 3mm thick OLED HDTV. Granted, this one was only 11" big, but this is going to be the wave of the future. The other real improvement is that these screens will be completely wireless and run only on battery power. This could make them perfect computer screens or home theater screens.
Organic light-emitting diodes use organic compounds for their electroluminescent layer. The layer contains some form of polymer. They are lain down in rows and columns by a simple printing process. OLEDs typically emit less light per area than inorganic LEDs, however OLEDs do not require a backlight function. This means that they consume a lot less power and can be used a lot longer when run from battery power. Since OLEDs don't need a backlight, they can be much thinner than LCD panels.
