      一、LED显示屏概述
      现代社会已进入信息时代,信息传播占有越来越重要的地位,同时人们对视觉媒体的要求也愈来愈高,要求传播媒体反映迅速、现实(实时性)、醒目(色彩丰富、栩栩如生),画面超大型化,具有震撼力,近几年,随着微电子技术、自动化技术、计算机技术的迅速发展,半导体制作工艺日趋成熟,导致LED显示点尺寸越来越小,解析度越来越高,并可将显示光的三基色(红、绿、蓝)集成化为一体,达到全彩色效果,使得LED显示屏的应用范围日益扩大。

     

      二、LED显示屏的特点
      LED显示屏主要有下列特点:
      1、屏幕尺寸可大可小,全部采用模块化无缝拼接,LED箱体设计的标准化使显示屏安装更为方便,独特的防水设计,符合IP65的防护等级,可直接在户外安装使用,最大可以做到2000㎡。
      2、视角大,亮度高,寿命长LED寿命长达100,000小时以上,室外屏亮度高于6000cd/㎡,室内屏亮度高于2000 cd/㎡,室内屏视角大于±120℃,室外屏视角大于±110℃,适用于不同的安装环境,可自行根据不同环境亮度来调整屏幕亮度。
      3、视距可通过选择不同直径与不同点距的产品来调整,小到几十厘米,大到几百米均可满足要求,目前最小直径可做到2mm。
      4、软件分区功能可以实现整屏的多窗口显示,可同时显示图像,实时显示,文本,时钟,支持远程无线和有线方式的集中管理,一个监控中心可以实现对多块LED显示屏的控制。

 

      三、LED显示屏使用环境
LED 显示屏按使用环境分为室内LED显示屏、半室外LED显示屏、室外LED显示屏
      1、户内屏面积一般从不到一平米到几十平米 , 点密度较高,在非阳光直射或灯光照明环境使用,观看距离在几米以外,屏体不具备密封防水能力。
      2、半户外屏介于户外及户内两者之间 , 具有较高的发光亮度 , 可在非阳光直射户外下使用,屏体有一定的密封,一般在屋檐下或橱窗内。
      3、户外屏面积一般从几平米到几十甚至上百平米,点密度较稀 ( 多为 1000-10000 点/㎡ ), 发光亮度在 3000-6000cd/㎡ ( 朝向不同,亮度要求不同 ) ,可在阳光直射条件下使用,观看距离在几十米以外,屏体具有良好的防风抗雨及防雷能力,LED显示屏可在全世界不同气候区使用,使用温度范围在-30℃-60℃,机箱具备良好的防潮耐腐蚀性能。
