FAQs (Frequently Asked Questions)

问:静态矩阵 LCD 和动态矩阵 LCD 有何区别?

答: LCD 若非由静态矩阵 格即由动态矩阵 格制作。动态矩阵的晶体管放在 每一像素交接点上,需少量电流即能控制像素的亮度。因此,动态矩阵显示器的 电流能够更加频繁的开关,增进屏幕刷新时间(例如,你的鼠标似乎在屏幕上滑 得更加平稳)。静态矩阵 LCD 具有一种导体 格,其像素位于 格的每一交接 点。

问: 与 CDT 相比,TFT LCD 的优势何在?

答:CDT 显示器中,一个电子枪以撞击荧光玻璃上的偏光电子方式发射电子和一

光。因此,CDT 显示器基本上以模拟红绿蓝信号操作。TFT LCD显示器则是运用 液晶屏面显示输入图像的装置。TFT与CDT有根本不同的结构:其每一晶胞皆有动 态矩阵结构和独立的活性元素。TFT LCD 有两个玻璃屏面,其空间装满液晶。当 每一晶胞接上电极并通上电压时,液晶分子结构则受到改变,从而控制从里面射 向显示图像的光。TFT LCD 比 CDT有多重优势,因为它能变得特别薄,又没有闪 光,原因是它不使用扫描法。

问: LCD 显示器的垂直频率为何最大只有 60 赫兹?

答:与 CDT 显示器不同,TFT LCD 屏幕具有固定的分辨率。例如,XGA显示器只 有1024x3(红绿蓝)x768个像素,而更高分辨率若无更多的软件处理则不可得。 本屏幕则定为 65赫兹点脉冲最大显示,即 XGA 显示器的标准频率之一。既然此 点脉冲是 60Hz/48kHz,此显示器的最大频率则为 60 赫兹。

问:现有何种广角技术?其功能如何?

答: TFT LCD 屏幕是透过液晶双重折射放进内部光亮的元素控制器/显示器。它 利用内部光折射至液体元素主轴的这一特性,控制内部光的方向、将光显示出 来。由于液晶上内部光的折射比率随光的内部角度变化,TFT 的视角比 CDT 的 视角更窄。通常,视角指对比度为 10 的角度点。目前有许多扩大视角的开发途 径。最常用的方法为利用广视角片,透过变换折射比率来扩大视角。IPS(面内 开关)或 MVA(多项垂直校准)也被用来扩大视角。飞利浦 181AS 型使用的则 是先进的 IPS 技术。
