style="text-indent:25px">發(fā)光二極管的中心部分是由P型半導(dǎo)體和N型半導(dǎo)體組成的晶片，在P型半導(dǎo)體和N型半導(dǎo)體之間有一個(gè)過(guò)渡層，稱為PN結(jié)。在某些半導(dǎo)體材料的PN結(jié)中，注入的少數(shù)載流子與多數(shù)載流子復(fù)合時(shí)會(huì)把多余的能量以光的形式釋放出來(lái)，從而把電能直接轉(zhuǎn)換為光能。PN結(jié)加反向電壓，少數(shù)載流子難以注入，故不發(fā)光。當(dāng)它處于正向工作狀態(tài)時(shí)（即兩端加上正向電壓），電流從LED陽(yáng)極流向陰極時(shí)，半導(dǎo)體晶體就發(fā)出從紫外到紅外不同顏色的光線，光的強(qiáng)弱與電流有關(guān)。</p><p style="text-indent:25px">LED表面平整度：顯示屏的表面平整度要在±1mm以內(nèi)，以保證顯示圖像不發(fā)生扭曲，局部凸起或凹進(jìn)會(huì)導(dǎo)致顯示屏的可視角度出現(xiàn)死角。平整度的好壞主要由生產(chǎn)工藝決定。性能參數(shù)：灰度：灰度也就是所謂的色階或灰階，是指亮度的明暗程度。對(duì)于LED數(shù)字化的顯示技術(shù)而言，灰度是顯示色彩數(shù)的決定因素。一般而言灰度越高，顯示的色彩越豐富，畫(huà)面也越細(xì)膩，更易表現(xiàn)豐富的細(xì)節(jié)。高刷新率：是指電子束對(duì)屏幕上的圖像重復(fù)掃描的次數(shù)較高。刷新率越高，所顯示的圖象(畫(huà)面)穩(wěn)定性就越好。刷新率高低將直接決定其價(jià)格，但是由于刷新率與分辨率兩者相互制約，因此只有在高分辨率下達(dá)到高刷新率這樣的顯示器才能稱其為性能較優(yōu)。目前市面上普通LED顯示屏的刷新率為800至1500HZ左右，超過(guò)4000HZ的為高刷新率。發(fā)光二級(jí)管這種電子元件早在1962年出現(xiàn)。</p><div
