What is tandem OLED technology?

If you’ve been keeping an eye on screen tech, you might have seen the term tandem OLED floating around. It was in the headlines around Apple’s latest ipad. Apple calls its version an ultra retina XDR display, and it’s supposed to be “the world’s most advanced display”. But what exactly does that mean?

Tandem OLED isn’t your typical OLED panel. Instead of a single layer of organic light-emitting pixels, tandem OLED stacks two layers on top of each other. This doubles the amount of light being produced, resulting in a much brighter display. While OLEDs are known as the best TVs, they’ve had a historical struggle with peak brightness compared to LED and LCD screens.

A standard OLED display works by using self-emissive pixels that light up independently, allowing for deep blacks and vibrant colours. The catch? OLED screens aren’t the brightest, which can make them tricky to see in direct sunlight or very bright environments.

Tandem OLED solves this by stacking two layers of OLED pixels on top of each other, working in unison. This means:

Higher brightness across the entire screen rather than just in highlights

More power efficiency, since each layer operates at a lower intensity

Better longevity, reducing the risk of burn-in and screen degradation
