LED backlit displays tend to display a truer colour gamut than their bulb counterparts, as well as having a backlight lifespan more superior as well.
There are also LCD display methods, such as TN, IPS, S-IPS, PVA (?) etc.
As mentioned, OLED emit the coloured light itself, as opposed to LCD which is more like a "light filter".
There were also other viable technologies that would have been interesting to see, such as Laser and SED.
