Apple's new iPad Pro screen technology analysis: Double-layer OLED brings a visual feast, but extreme use still requires caution

Apple recently released its new generation iPad Pro (M4), equipped with ultra-precise Retina XDR display technology. This display has attracted a lot of attention for its excellent visual performance.

Apple describes that the Super Retina XDR display uses advanced OLED technology to provide excellent high dynamic range (HDR) effects. This technology brings users a more realistic visual experience through high contrast and high brightness performance. Unlike traditional LCD screens, each pixel of an OLED screen can emit light independently without the need for a backlight, making the screen purer.

In order to achieve high brightness performance on a large screen, iPad Pro uses a unique double-layer OLED design, namely Tandem OLED. This design allows the light from the two-layer OLED panels to be superimposed and fused, thereby achieving an SDR brightness of up to 1,000 nits, and an HDR brightness of 1,600 nits.

However, long-term use of OLED screens may cause "image retention" or "screen burn". Apple has taken several precautionary measures. According to the editor’s understanding, Apple claims that its Super Retina XDR display has the best anti-burning technology in the industry. The technology monitors the usage of each pixel through a special algorithm, generates display calibration data, and automatically adjusts the brightness level of each pixel based on this. This innovative move not only reduces the visual effect of screen burn-in, but also ensures that users can enjoy a consistent viewing experience.
