像素位移：OLED屏幕如何避免烧屏

OLED displays create light directly in each red, green, or blue sub-pixel, unlike LCDs.
But static images—like navigation bars or logos—cause some pixels to age faster than others.
This uneven wear leads to permanent ghost images known as burn-in.
To prevent it, modern OLED TVs and phones subtly shift the entire screen image by one or two pixels every few minutes.
The movement is too small for users to notice, yet it spreads wear across neighboring pixels.
Advanced algorithms track which areas stay fixed longest and prioritize shifting those zones.
Some devices combine pixel shifting with automatic brightness reduction for static content.
Together, these strategies extend display lifespan by up to 40% under heavy use.
Manufacturers now guarantee zero visible burn-in for at least three years of normal viewing.
It’s a clever software-hardware dance that protects your screen invisibly.

It’s a clever software-hardware dance that protects your screen invisibly. 这是一场软硬件默契配合的隐形护屏之舞。
This uneven wear leads to permanent ghost images known as burn-in. 这种不均匀老化会形成永久性残影，即‘烧屏’。
Some devices combine pixel shifting with automatic brightness reduction for static content. 部分设备还将像素位移与静态内容自动降亮相结合。
