Laser displays have a wider color reproduction compared with OLED, and Mitshubishi have one.
Some LCD have led back-light, and have similar gamut with OLED. These displays are a little bit short of contrast ratio, but is compensated with local dimming of LEDs. Practically offer same image quality.
With similar quality LCD compared with OLED, and apparition of superior technology (laser TV), i don’t see future in OLED technology.
