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，遼寧小區(qū)LED，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，遼寧小區(qū)LED，所顯示的圖象(畫(huà)面)穩(wěn)定性就越好，遼寧小區(qū)LED。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)光二極管是一種常用的發(fā)光器件，通過(guò)電子與空穴復(fù)合釋放能量發(fā)光。遼寧小區(qū)LED</p><div

“干凈”。LED的光學(xué)參數(shù)中重要的幾個(gè)方面就是：光通量、發(fā)光效率、發(fā)光強(qiáng)度、光強(qiáng)分布、波長(zhǎng)。發(fā)光效率就是光通量與電功率之比，單位一般為lm/W。發(fā)光效率表示了光源的節(jié)能特性，這是衡量現(xiàn)代光源性能的一個(gè)重要指標(biāo)。遼寧小區(qū)LED目前采用LED的發(fā)光峰值波長(zhǎng)是紅色630nm，黃色590nm，綠色505nm。</p><div
