了解坏点测试
坏点测试是任何新旧显示器最基本、最重要的检查。像素缺陷会分散注意力，并且通常在制造商的保修范围内。我们的工具使您无需安装任何软件即可轻松发现这些问题。
您要找的是什么？
当您进行坏点测试时，您要寻找的是任何表现异常的像素。主要有三种类型的像素缺陷：
- 坏点：当所有三个子像素（红、绿、蓝）都永久关闭时发生。它们显示为一个小的黑色方块，在白色或亮色背景上最容易发现。
- 卡住的像素：当一个或两个子像素永久点亮时发生。这导致像素卡在一种颜色上——红色、绿色、蓝色、青色、品红色或黄色。在我们测试的所有纯色背景中循环切换最容易发现卡住的像素。
- 亮点：当所有子像素永久点亮时发生，使像素总是显示为白色。亮点在坏点测试的黑屏部分最明显。
