磷质烙印 Screen burn-in

(重定向自Screen Burn)
出现在琥珀色的单色阴极射线管(CRT)电脑显示器上的磷质烙印。

磷质烙印也就是俗称的屏幕灼伤烧印,是一种出现在阴极射线管显示屏上的、永久性的区域损伤。其表现为一些原先影像在显示屏上留下长久不褪的残影。磷质烙印是由长时间显示静止的文本或图像而导致。

现代LCD、LED和等离子显示屏也有可能出现烙印现象,故此电脑、新款的电视机也设有定时关机的保护功能。现在的映像管屏幕比起以前较不受到磷质烙印的影响,这要归功于对磷光薄膜的改良和如今电脑图像的低对比度,而早期的图像大多为黑白的。液晶显示器不会有磷质烙印的问题因为影像不是直接靠磷光体产生的(但有可能产生暂时的烙印现象)。
