Pixel Shifting: How OLED Screens Avoid Burn-In

课文

1. OLED displays create light directly in each red, green, or blue sub-pixel, unlike LCDs.

   OLED屏幕的每个红、绿、蓝子像素可自主发光，而LCD则不能。

2. But static images—like navigation bars or logos—cause some pixels to age faster than others.

   但静态图像（如导航栏或标志）会导致部分像素老化更快。

3. 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’。

4. To prevent it, modern OLED TVs and phones subtly shift the entire screen image by one or two pixels every few minutes.

   为防止烧屏，现代OLED电视和手机每隔几分钟便将整屏图像微移一至两个像素。

5. The movement is too small for users to notice, yet it spreads wear across neighboring pixels.

   位移幅度极小，用户难以察觉，却能将损耗分散到邻近像素。

6. Advanced algorithms track which areas stay fixed longest and prioritize shifting those zones.

   先进算法会追踪停留时间最长的区域，并优先移动这些区域。

7. 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。

8. Together, these strategies extend display lifespan by up to 40% under heavy use.

   这些策略协同作用，可在高强度使用下延长屏幕寿命达40%。

9. Manufacturers now guarantee zero visible burn-in for at least three years of normal viewing.

   厂商目前承诺：正常观看三年内屏幕无可见烧屏。

10. It’s a clever software-hardware dance that protects your screen invisibly.

    这是一场软硬件默契配合、悄然守护屏幕的精巧协作。
