style="text-indent:25px">LED顯示屏，自20世紀(jì)80年代中期，就有單色和多色顯示屏問世，起初是文字屏或動(dòng)畫屏。90年代初，電子計(jì)算機(jī)技術(shù)和集成電路技術(shù)的發(fā)展，使得LED顯示屏的視頻技術(shù)得以實(shí)現(xiàn)，電視圖像直接上屏，特別是90年代中期，藍(lán)色和綠色超高亮度LED研制成功并迅速投產(chǎn)，使室外屏的應(yīng)用較大擴(kuò)展，面積在100—300m不等。目前LED顯示屏在體育場(chǎng)館、廣場(chǎng)、會(huì)場(chǎng)甚至街道、商場(chǎng)都已較廣應(yīng)用，美國時(shí)代廣場(chǎng)上的納斯達(dá)克全彩屏較為聞名，該屏面積為120英尺×90英尺，相當(dāng)于1005m，由1900萬只超高亮藍(lán)、綠、紅色LED制成。LED在照明領(lǐng)域應(yīng)用較廣。天津普通LED燈帶</p><p
