屏幕坏点测试.
以全屏纯色检测屏幕坏点和亮点。支持手动或自动切换颜色，无闪烁。
清洁屏幕，进入全屏，仔细查看每种纯色上是否有异常的点。
在所有颜色下都保持黑色的点是坏点；始终显示同一种颜色的点是亮点（卡住的像素）。擦拭屏幕时灰尘会移动。本测试不会修复像素，也不使用快速闪烁。

英语技术说明
Visual inspection only: the browser cannot detect defective pixels automatically, and this tool does not repair stuck pixels. Full screen depends on browser support; where it is unavailable, such as on iPhone, the colors fill the page instead.
Each color fills the whole display at full intensity. Automatic mode changes color every 3 seconds; there is no rapid flashing. The cursor and instructions hide after a moment so they are not mistaken for a defect.
A dot that stays black on white and colored screens is a dead pixel; a dot that remains bright red on black is a stuck subpixel.
