The three main display manufacturers NEC, Samsung and LG have all invested in the LED space. The newest kid in town is OLED: With self-lighting pixels OLED displays can be paper-thin. Even double-sided displays, curved in various directions will complement LCD and LED in the near future.

LG seems to be most advanced with their plans in launching an OLED professional product next year. Consumer TVs are already available since 2015. Selected digital signage experts have already seen prototypes of professional digital signage solutions and they are very excited.
