一、整機穩定性（包括使用時間、抗干擾等）
液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)在(zai)構成數(shu)字告示系統時(shi)(shi)(shi)，通(tong)(tong)(tong)(tong)常需要天(tian)(tian)天(tian)(tian)24小(xiao)時(shi)(shi)(shi)，每(mei)年365天(tian)(tian)連續無中斷的(de)(de)(de)(de)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)使(shi)(shi)(shi)(shi)用(而(er)(er)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)(ji)通(tong)(tong)(tong)(tong)常天(tian)(tian)天(tian)(tian)僅工(gong)作幾小(xiao)時(shi)(shi)(shi))，并且某些拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)應用環(huan)(huan)境可能(neng)較為惡劣(lie)，這(zhe)就(jiu)要求液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)可靠(kao)性和穩定(ding)性更高(gao)(gao)。與(yu)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)(ji)相比而(er)(er)言，在(zai)設計上(shang)，液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)、功耗、溫(wen)(wen)度(du)及(ji)抗電(dian)(dian)(dian)(dian)(dian)干擾、電(dian)(dian)(dian)(dian)(dian)沖(chong)擊的(de)(de)(de)(de)能(neng)力和裕(yu)度(du)以及(ji)均(jun)勻無故障(zhang)使(shi)(shi)(shi)(shi)用時(shi)(shi)(shi)間均(jun)要遠大于電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)(ji)，同時(shi)(shi)(shi)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)還必須(xu)使(shi)(shi)(shi)(shi)用全屏(ping)(ping)(ping)蔽金屬外殼確保電(dian)(dian)(dian)(dian)(dian)磁兼容和干擾性能(neng)；在(zai)元器件(jian)(jian)的(de)(de)(de)(de)選型上(shang)，液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)使(shi)(shi)(shi)(shi)用的(de)(de)(de)(de)元器件(jian)(jian)的(de)(de)(de)(de)耐壓、電(dian)(dian)(dian)(dian)(dian)流(liu)、溫(wen)(wen)度(du)、濕度(du)等各方面特性都要高(gao)(gao)于電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)(ji)使(shi)(shi)(shi)(shi)用的(de)(de)(de)(de)元器件(jian)(jian)；而(er)(er)在(zai)安裝、調試尤其是元器件(jian)(jian)和整(zheng)(zheng)機(ji)(ji)(ji)(ji)老化(hua)的(de)(de)(de)(de)工(gong)藝要求上(shang)，液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)要求也更高(gao)(gao)，電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)(ji)制造時(shi)(shi)(shi)整(zheng)(zheng)機(ji)(ji)(ji)(ji)老化(hua)通(tong)(tong)(tong)(tong)常是在(zai)流(liu)水線上(shang)常溫(wen)(wen)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)8小(xiao)時(shi)(shi)(shi)左右，而(er)(er)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)整(zheng)(zheng)機(ji)(ji)(ji)(ji)老化(hua)則(ze)需要在(zai)高(gao)(gao)溫(wen)(wen)、高(gao)(gao)濕密閉(bi)環(huan)(huan)境的(de)(de)(de)(de)老化(hua)流(liu)水線上(shang)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)老化(hua)24小(xiao)時(shi)(shi)(shi)以上(shang)，以確保整(zheng)(zheng)機(ji)(ji)(ji)(ji)的(de)(de)(de)(de)穩定(ding)性。普通(tong)(tong)(tong)(tong)的(de)(de)(de)(de)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)使(shi)(shi)(shi)(shi)用的(de)(de)(de)(de)LCD液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)屏(ping)(ping)(ping)其背光源的(de)(de)(de)(de)使(shi)(shi)(shi)(shi)用壽命為1萬(wan)至3萬(wan)小(xiao)時(shi)(shi)(shi)，而(er)(er)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)背光源的(de)(de)(de)(de)使(shi)(shi)(shi)(shi)用壽命均(jun)可達6-7萬(wan)小(xiao)時(shi)(shi)(shi)以上(shang)。液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接屏(ping)(ping)(ping)廠家
二、圖像清楚度
液(ye)晶(jing)拼(pin)接(jie)顯(xian)示用具有直觀反映圖像(xiang)質量的(de)(de)(de)(de)功能(neng)，加之全1920*1080分辨率對于數(shu)字告示領域的(de)(de)(de)(de)顯(xian)示設備(bei)的(de)(de)(de)(de)選用，液(ye)晶(jing)拼(pin)接(jie)屏是優先選擇(ze)的(de)(de)(de)(de)拼(pin)接(jie)屏，專(zhuan)業拼(pin)接(jie)屏分辨率是根據顯(xian)示輸出自動調(diao)整(zheng)分辨率（不管橫豎都(dou)可(ke)以(yi)支(zhi)持）；其高可(ke)靠性和高清楚(chu)顯(xian)示能(neng)力將保證您可(ke)以(yi)將記錄(lu)編輯好的(de)(de)(de)(de)高清楚(chu)影音，視(shi)頻信號完整(zheng)的(de)(de)(de)(de)顯(xian)示在觀看(kan)者眼前。
反之，液晶(jing)電(dian)視(shi)(shi)(shi)只(zhi)支持(chi)說明書中規定的(de)幾(ji)種(zhong)電(dian)視(shi)(shi)(shi)常用(yong)(yong)分(fen)辨(bian)率。由于(yu)民用(yong)(yong)電(dian)視(shi)(shi)(shi)信號的(de)分(fen)辨(bian)率只(zhi)有幾(ji)種(zhong)，電(dian)視(shi)(shi)(shi)LCD只(zhi)要根據民用(yong)(yong)用(yong)(yong)戶使用(yong)(yong)的(de)常用(yong)(yong)幾(ji)個分(fen)辨(bian)率進行效果處理，特殊(shu)分(fen)辨(bian)率會導致花屏(ping)。
三、色彩還原度
假如(ru)說(shuo)清楚度(du)(du)主要是由視頻(pin)通(tong)道的(de)(de)幅(fu)頻(pin)特性決(jue)定的(de)(de)話，還原(yuan)度(du)(du)則主要由液(ye)晶拼接屏中有紅(R)、綠(G)、藍(B)三(san)基色(se)的(de)(de)色(se)度(du)(du)信號和(he)亮(liang)度(du)(du)信號的(de)(de)相(xiang)(xiang)位(wei)(wei)所決(jue)定。由于液(ye)晶拼接屏所觀察的(de)(de)通(tong)常為靜態圖像，因而對拼接屏色(se)彩還原(yuan)度(du)(du)的(de)(de)要求(qiu)比(bi)電(dian)視機更高，故(gu)專業拼接屏的(de)(de)視放通(tong)道在亮(liang)度(du)(du)、色(se)度(du)(du)處理和(he)R、G、B處理上應具備的(de)(de)補(bu)償電(dian)路和(he)延遲電(dian)路，以確保(bao)亮(liang)/色(se)信號和(he)R、G、B信號的(de)(de)相(xiang)(xiang)位(wei)(wei)同步。
反之(zhi)，液晶電(dian)視由(you)于使用環境要(yao)求(qiu)所至，圖象是經過潤色(se)處(chu)理后進行(xing)顯示。不能完全真實(shi)(shi)反映實(shi)(shi)際效果。
四、機器材料的使用
由于(yu)使(shi)用(yong)環(huan)(huan)境的(de)要求，液晶(jing)電(dian)視(shi)機(ji)器外殼材(cai)質部分采(cai)用(yong)金屬質地(di)。且內部板線都是(shi)產業化設(she)計(ji)，不輕(qing)易老化；節能(neng)環(huan)(huan)保(bao)(bao)理念的(de)體現：低能(neng)耗設(she)計(ji)；環(huan)(huan)保(bao)(bao)材(cai)料使(shi)用(yong)。規整(zheng)的(de)外觀，便于(yu)拼接，組合安裝等產業需要。
反(fan)之，液晶(jing)電視整(zheng)(zheng)機(ji)外(wai)殼全部為(wei)(wei)非金屬(shu)材質設(she)計(ji)。內部板線是(shi)采用民用設(she)計(ji)，長時間開機(ji)輕易造成(cheng)機(ji)件(jian)老化(hua)。另外(wai)民用電視外(wai)觀多是(shi)非規則(ze)外(wai)觀，附帶數字(zi)標牌(pai)拼(pin)接屏系統、外(wai)觀圓弧(hu)系統等作為(wei)(wei)聽覺(jue)和視覺(jue)的附屬(shu)設(she)施(shi)，施(shi)工起來整(zheng)(zheng)體美觀和效果都會大打折扣。
五、端口
液晶拼接(jie)屏(ping)多(duo)采用產(chan)業端口(kou)例(li)如RGBBNC的色(se)差帶自鎖機(ji)構的接(jie)口(kou)和專業的DVI-D視頻接(jie)口(kou)；
反之，液(ye)晶電視則沒有(you)BNC自鎖色差輸進接口和DVI-D接口；
六、控制接口
液晶拼(pin)接(jie)屏(ping)可采用S232串口控制，開(kai)放的控制口令多(duo)達(da)200多(duo)條，適應各種產(chan)業(ye)環(huan)境(jing)。方便(bian)多(duo)拼(pin)接(jie)屏(ping)使用時(shi)，不用通過遠控器(qi)就可以控制所有顯示設備，并(bing)能夠輔(fu)助，定時(shi)開(kai)機，延時(shi)開(kai)機、機器(qi)自檢等各種產(chan)業(ye)要求。
反之，液晶電視也可(ke)采用S232串口控制(zhi)(zhi)。但只(zhi)能實現遠控器所(suo)具備的控制(zhi)(zhi)指令。并不能實現產業控制(zhi)(zhi)。
七、無風扇架構
液晶拼接屏在設計上采(cai)用(yong)無機(ji)械(xie)排風(feng)扇來保持空(kong)氣流通和散熱，從而避(bi)免由于機(ji)械(xie)排風(feng)扇導致的灰塵和風(feng)扇噪(zao)音題目，當內(nei)部溫(wen)度(du)(du)由于不明原因而升高時(shi)，液晶拼接屏自動(dong)控制背光系統將溫(wen)度(du)(du)保持在比較高工作溫(wen)度(du)(du)之(zhi)下(xia)。
反之，液(ye)晶電視由于應(ying)用(yong)的環(huan)境所致，對此(ci)無嚴格要(yao)求。
八．亮度
普通的液晶電(dian)視(shi)亮度只有(you)200cd/m2,而拼接(jie)拼可以達(da)到450cd/m2或(huo)者(zhe)700cd/m2
