因此，通過(guò)實(shí)踐我們的結(jié)論是：后續(xù)校正**是治表，而LED參數(shù)細(xì)分才是治本，才是LED顯示屏產(chǎn)業(yè)未來(lái)的主流。而論到顯示屏均勻性與清晰度的關(guān)系，業(yè)界則常常存在一個(gè)認(rèn)識(shí)上的誤區(qū)，即以分辨率替代清晰度。其實(shí)LED顯示屏清晰度是人眼對(duì)顯示屏分辨率、均勻性(信噪比)、亮度、對(duì)比度等多項(xiàng)因素綜合的主觀感受。單純縮小物理像素間距提高分辨率，而忽視均勻性，對(duì)提高清晰度是毫無(wú)疑義的。試想一個(gè)存有嚴(yán)重“灰塵效應(yīng)”和“馬賽克現(xiàn)象”的LED顯示屏，即使它的物理像素間距再小，分辨率再高，也不可能得到一個(gè)良好的圖像清晰度。在10%～65%RH的環(huán)境濕度下，LED示屏每天至少開(kāi)屏1次，每次確保正常工作4小時(shí)以上。</p><div

說(shuō)到LED顯示屏，這在我們?nèi)粘Ｉ钪袠O其常見(jiàn)。有時(shí)候，只是去商場(chǎng)轉(zhuǎn)一圈，就會(huì)看到在商場(chǎng)的外側(cè)墻面上放著大型廣告?？梢赃@樣說(shuō)，LED顯示屏存在于一些人員流動(dòng)較多的地方，另外，其在高速路上也比較常見(jiàn)。接下來(lái)，我想要跟大家介紹一下它的掃描方式，主要分為兩大方面。一、LED顯示屏掃描方式:1、動(dòng)態(tài)掃描。是指從驅(qū)動(dòng)IC的輸出到像素點(diǎn)之間實(shí)行“點(diǎn)對(duì)列”的控制,成本比靜態(tài)掃描要低,顯示效果較差；2、靜態(tài)掃描。其實(shí)行“點(diǎn)對(duì)點(diǎn)”的控制,本高于動(dòng)態(tài)掃描,但是它具有一個(gè)明顯的優(yōu)勢(shì)，其顯示效果更好,同時(shí)也更加穩(wěn)定。二、按照LED顯示屏類(lèi)型掃描方式分類(lèi)：1、室內(nèi)全彩LED電子顯示屏的掃描方式:P4、P5為恒流1/16,P6、；2、戶(hù)外全彩LED電子顯示屏的掃描方式:P10、P12為恒流1/2、1/4,P16、P20、P25為靜態(tài)；3、單雙色LED電子顯示屏的掃描方式主要是恒流1/4、恒流1/8掃、恒流1/16掃。我們平時(shí)只不過(guò)看到LED顯示屏的次數(shù)較多，實(shí)際上并不了解行業(yè)的深度知識(shí)。人活著就應(yīng)當(dāng)多學(xué)習(xí)，不求任何話題皆有談資，至少知道得越多也會(huì)越好。長(zhǎng)沙戶(hù)外LED顯示屏多少錢(qián)</p><p
