OLED 烧屏是由像素退化不均引起的永久性图像残留。这在静态 UI 元素（如任务栏或新闻滚动条）中最为常见。我们的 50% 灰阶模式是检测早期烧屏的行业标准。
OLED 的少数弱点之一是“压碎”近黑细节。高质量的 OLED 应该能显示 0% 和 1% 黑色之间的差异。使用我们的黑电平工具来校准您的伽马设置。
OLED burn-in is permanent image retention caused by uneven degradation of organic light-emitting diodes. When static content (like taskbars, HUDs, or channel logos) remains on screen for extended periods, those subpixels degrade faster, leaving a faint shadow or ghost image.
Our tool generates full-screen 5%, 20%, and 50% neutral gray patterns, pure primary colors, and near-black gradients. Gray and solid color slides reveal subtle uneven pixel aging and banding that are invisible during normal video playback.
Temporary image retention can often be resolved using pixel refresh / pixel cleaning cycles built into your monitor. True permanent burn-in cannot be undone by software, but can be prevented with dark mode, auto-hiding taskbars, and regular pixel shifting.
Black crush occurs when near-black dark gray shades (levels 1-5%) are clipped into absolute pure black (0%), causing shadow details in movies or games to disappear. Our Black Level test pattern helps you calibrate brightness and gamma to preserve dark details.
