View an LCD screen straight on, and it’ll look great. But look at the screen from an angle, and once-bright colours are likely to lose their lustre. One tech for tackling this problem: IPS (it stands for “in-plane switching”) LCD screens – a Hitachideveloped technology that has been around since 1996 but is gaining newfound prominence, thanks to its inclusion in the Apple iPad. These screens work by aligning their liquid crystals with the panel plane, instead of perpendicular to it. The result is a wider viewing angle with little to no colour shifting.
