     今天,小编将要给大家分享的是显示器的知识以及显示器的清理技巧。如今液晶显示器已经成为主流,CRT显示器已经逐渐退出历史舞台。那么,关于液晶显示器大家了解多少呢?请看下面的详细介绍,希望对电脑爱好者朋友有所参考。

  一、液晶显示器--目前可分为LCD与LED液晶显示器 LED显示器与LCD显示器    1)液晶显示器比较薄,占用的空间小省电,对眼睛刺激较小,(电脑配置网)缺点是显示的图像画面较暗;   2)显示器上有两条线,线比较粗两头有一个圆疙瘩的是信号线,接头是梯形的,颜色是蓝色,另外一条是电源线,是三相插头;   3)显示器的开关一般在屏幕右下角,最大的一个就是,另外几个是调节亮度对比度的;   4)在桌面点右键-属性-设置,进入显示器的分辨率,一般系统会自动调节,有1200×800、1024×768等,刷新率一般是60或75;   5)分辨率越大,屏幕显示的内容也越多,但是字体也会越小,刷新率越高屏幕就越不闪,但过高会损害显示器,产生黑屏;      LED显示器是指采用白光LED背光的显示器产品,和普通液晶显示器的区别是背光源的改变。其实说的简单点,商家所说的LED显示器就是LED背光显示器,真正的LED显示器暂时还没有应用到桌面显示器上。相对于CCFL背光显示器,只是改变背光源而已。总的来说LED背光显示器和CCFL背光显示器都是LCD,所以厂商和商家所说的LED和LCD两个概念,是错误的。   二、CRT 显示器--以前的显示器   1)CRT 显示器使用阴极射线管,跟电视机挺相似,耗电量高,对眼睛刺激较大,优点是屏幕颜色显示丰富,显示速度快刷新率高;   2)CRT 显示器在图像处理,玩一些大型游戏上比较好,常用的还是液晶较多;   3)CRT 显示器的分辨率也是1024×768、1280×1024等,刷新率一般在85以上;   三、显示器维护 CRT 显示器    1)清洁 CRT 显示器可以用软布,湿润后尽量拧干,轻轻擦拭显示器外壳和屏幕;   2)CRT 显示器附近不能有磁铁、音箱、喇叭等磁性物体,以免造成颜色紊乱,面板上一般有消磁按钮,开启时也会自动消磁;   3)CRT 显示器上有散热孔,开机的时候注意通风散热,显示器背后的辐射较多,不要离太近;   4)液晶显示器屏幕上一般有塑料保护膜,可以阻挡灰尘,如果屏幕上落有灰尘,可以用吹气球吹去,操作要轻柔。       需要注意的问题是,清洗一定要在关机状态下进行。清洗剂及清洗抹布我们可以到卖电脑的商店去购买,也很便宜!买电脑的地方一般都有整套的清洗工具,使用很方便,大家可以买来用下试试看。希望这篇教程对大家有所帮助!(责任编辑:admin)
