OLED is ex­pen­sive… but there’s a rea­son for that. The ‘O’ stands for ‘or­ganic’, and each in­di­vid­ual OLED pixel emits its own light when you pass an elec­tri­cal cur­rent through it. LCDs re­quire a light source be­hind them in or­der to shine – and even if you di­vide that back­light into por­tions, it’ll never be as pre­cise. Plus, OLED pix­els can be turned off in­di­vid­u­ally, which is what gives you those deep blacks right next to daz­zling bright colours.
