戶外LED顯示屏是一種非常常用的顯示屏幕類型，四川門頭LED顯示屏供應(yīng)商，不僅擁有靈活的安裝尺寸，同時(shí)在重量方面和傳統(tǒng)產(chǎn)品相比有了極大的改善，而且色彩更為清晰飽滿，能夠讓大家看到更為賞心悅目的視頻畫面。那么要想買到質(zhì)量好的戶外LED顯示屏，我們應(yīng)該注意哪些方面呢？以下就是選購(gòu)戶外LED顯示屏要注意的一些事項(xiàng)。為了保證顯示圖像不會(huì)發(fā)生扭曲，那么戶外LED顯示屏的表面平整度就一定要保持在±1mm以內(nèi)，如果達(dá)不到這個(gè)要求，并且局部出現(xiàn)凹凸的現(xiàn)象就會(huì)導(dǎo)致戶外LED顯示屏在播放視頻時(shí)出現(xiàn)可視角度有死角的問(wèn)題，四川門頭LED顯示屏供應(yīng)商。因此，可以說(shuō)平整度是判斷質(zhì)量戶外LED顯示屏的一個(gè)主要因素，四川門頭LED顯示屏供應(yīng)商。室外LED顯示屏在室外環(huán)境下使用，此類顯示屏亮度高、混色距離遠(yuǎn)、防護(hù)等級(jí)高、防水，適合遠(yuǎn)距離觀看。四川門頭LED顯示屏供應(yīng)商</p><div

所謂LED顯示屏像素失控率是指顯示屏**小成像單元不正常工作在整個(gè)過(guò)程中所站的比率。像素失控率表現(xiàn)為兩種模式，一種是盲點(diǎn)，即瞎點(diǎn)，就是打開(kāi)亮度開(kāi)關(guān)時(shí)它不顯示亮度；另一種是常亮點(diǎn)，就是在關(guān)閉亮度開(kāi)關(guān)時(shí)它一直在亮。像素由2顆紅燈、1顆綠燈和1顆藍(lán)燈組成，在同一個(gè)像素里，這幾個(gè)燈不會(huì)同時(shí)失控，但是只要有一個(gè)燈失控，我們就稱之為L(zhǎng)ED顯示屏像素的失控。像素的失控?cái)?shù)與全屏像素總數(shù)的比率，我們稱之為“整屏像素失控率”。相對(duì)應(yīng)的，還有“區(qū)域像素失控率”，即在在100×100像素區(qū)域內(nèi)，失控的像素?cái)?shù)占區(qū)域像素總數(shù)（即10000）的比率。
