了解壞點測試
壞點測試是任何新舊螢幕最基本、最重要的檢查。像素缺陷會分散注意力，並且通常在製造商的保固範圍內。我們的工具使您無需安裝任何軟體即可輕鬆發現這些問題。
您要找的是什麼？
當您進行壞点測試時，您要尋找的是任何表現異常的像素。主要有三種類型的像素缺陷：
- 壞點：當所有三個子像素（紅、綠、藍）都永久關閉時發生。它們顯示為一個小的黑色方塊，在白色或亮色背景上最容易發現。
- 卡住的像素：當一個或兩個子像素永久點亮時發生。這導致像素卡在某種顏色上——紅色、綠色、藍色、青色、品紅色或黃色。在我們測試的所有純色背景中循環切換最容易發現卡住的像素。
- 亮點：當所有子像素永久點亮時發生，使像素總是顯示為白色。亮點在壞點測試的黑螢幕部分最明顯。
