LCD屏幕技术

问: 何为液晶显示器?

答:液晶显示器(LCD)是一种光学装置,通常用在数字物件上显示 ASCII 字符和 图形,例如手表、计算器、携带式游戏控制仪,等等。LCD便是使用于手提电脑 和其它小型电脑的技术。与发光二极管和气体-等离子技术相仿,LCD 较之阴极 射线管技术,能使显示器变得更薄。LCD 比大型电子显示器(LED)和气体显示器 更加节省能源,因为它的使用原则是蔽光而不是发光。

问:静态矩阵 LCD 和动态矩阵 LCD 有何区别?

答: LCD 若非由静态矩阵栅格即由动态矩阵栅格制作。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 具有一种导体栅格,其像素位于栅格的每一交接 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 般光。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CRT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?
