Modern displays use a liquid crystal display (lcd) panel & light emitting diodes (leds) to produce image on screen. Accurate reproduction of fast moving images (e. g. , gaming) Colours appear distorted when viewed from off-centre angles. Better reproduction of colours, especially when viewed from angles.
