Quality control is vital for monitors.
顯示器的品質能保持不便嗎?
顯示的品質取決於亮度，灰階和亮度的均勻度會隨著時間而有些微的變化。
---------------------------------------------------------------------------------
當顯示器品值改變時會有什麼情況?
在醫院，在診斷時使用兩台以上不同的螢幕觀看同樣圖片時，在每個螢幕下的任何改變或是彼 此之間不同都會造成嚴重的問題。
---------------------------------------------------------------------------------
如何維持顯示器的品質?
顯示器的品質管理(QC)昰被要求作檢驗的和針對顯示器的 特性的些微改變來做校正，讓品質維持ㄧ致的穩定性。
