一、整機穩定性（包括使用時間、抗干擾等）
液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)在(zai)構成數字(zi)告(gao)示系統時(shi)(shi)(shi)，通(tong)(tong)(tong)(tong)常(chang)需要(yao)(yao)(yao)(yao)天(tian)(tian)天(tian)(tian)24小(xiao)時(shi)(shi)(shi)，每年365天(tian)(tian)連(lian)續無(wu)中斷的(de)(de)(de)(de)(de)(de)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)使(shi)用(yong)(而電(dian)(dian)(dian)視機(ji)(ji)(ji)(ji)通(tong)(tong)(tong)(tong)常(chang)天(tian)(tian)天(tian)(tian)僅(jin)工(gong)作幾小(xiao)時(shi)(shi)(shi))，并(bing)且某些拼(pin)接(jie)(jie)(jie)屏(ping)的(de)(de)(de)(de)(de)(de)應(ying)用(yong)環境可(ke)能(neng)(neng)較為惡劣，這就要(yao)(yao)(yao)(yao)求液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)的(de)(de)(de)(de)(de)(de)可(ke)靠性和(he)穩定性更(geng)高。與電(dian)(dian)(dian)視機(ji)(ji)(ji)(ji)相比而言，在(zai)設計(ji)上(shang)，液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)流、功耗、溫(wen)度(du)(du)(du)及抗電(dian)(dian)(dian)干(gan)擾(rao)、電(dian)(dian)(dian)沖擊的(de)(de)(de)(de)(de)(de)能(neng)(neng)力和(he)裕度(du)(du)(du)以(yi)(yi)及均(jun)勻無(wu)故障使(shi)用(yong)時(shi)(shi)(shi)間(jian)均(jun)要(yao)(yao)(yao)(yao)遠大于電(dian)(dian)(dian)視機(ji)(ji)(ji)(ji)，同時(shi)(shi)(shi)液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)還必須使(shi)用(yong)全屏(ping)蔽金屬外殼(ke)確保電(dian)(dian)(dian)磁(ci)兼容和(he)干(gan)擾(rao)性能(neng)(neng)；在(zai)元器件的(de)(de)(de)(de)(de)(de)選型上(shang)，液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)使(shi)用(yong)的(de)(de)(de)(de)(de)(de)元器件的(de)(de)(de)(de)(de)(de)耐壓、電(dian)(dian)(dian)流、溫(wen)度(du)(du)(du)、濕度(du)(du)(du)等各方(fang)面特(te)性都要(yao)(yao)(yao)(yao)高于電(dian)(dian)(dian)視機(ji)(ji)(ji)(ji)使(shi)用(yong)的(de)(de)(de)(de)(de)(de)元器件；而在(zai)安裝、調(diao)試(shi)尤(you)其是元器件和(he)整(zheng)(zheng)機(ji)(ji)(ji)(ji)老(lao)(lao)化的(de)(de)(de)(de)(de)(de)工(gong)藝要(yao)(yao)(yao)(yao)求上(shang)，液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)的(de)(de)(de)(de)(de)(de)要(yao)(yao)(yao)(yao)求也更(geng)高，電(dian)(dian)(dian)視機(ji)(ji)(ji)(ji)制造(zao)時(shi)(shi)(shi)整(zheng)(zheng)機(ji)(ji)(ji)(ji)老(lao)(lao)化通(tong)(tong)(tong)(tong)常(chang)是在(zai)流水線上(shang)常(chang)溫(wen)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)8小(xiao)時(shi)(shi)(shi)左右，而液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)的(de)(de)(de)(de)(de)(de)整(zheng)(zheng)機(ji)(ji)(ji)(ji)老(lao)(lao)化則需要(yao)(yao)(yao)(yao)在(zai)高溫(wen)、高濕密閉環境的(de)(de)(de)(de)(de)(de)老(lao)(lao)化流水線上(shang)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)老(lao)(lao)化24小(xiao)時(shi)(shi)(shi)以(yi)(yi)上(shang)，以(yi)(yi)確保整(zheng)(zheng)機(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)穩定性。普通(tong)(tong)(tong)(tong)的(de)(de)(de)(de)(de)(de)液(ye)(ye)晶(jing)電(dian)(dian)(dian)視使(shi)用(yong)的(de)(de)(de)(de)(de)(de)LCD液(ye)(ye)晶(jing)屏(ping)其背(bei)光(guang)源的(de)(de)(de)(de)(de)(de)使(shi)用(yong)壽命為1萬至3萬小(xiao)時(shi)(shi)(shi)，而液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)背(bei)光(guang)源的(de)(de)(de)(de)(de)(de)使(shi)用(yong)壽命均(jun)可(ke)達(da)6-7萬小(xiao)時(shi)(shi)(shi)以(yi)(yi)上(shang)。液(ye)(ye)晶(jing)拼(pin)接(jie)(jie)(jie)屏(ping)廠家
二、圖像清楚度
液晶(jing)拼接(jie)顯(xian)(xian)示用具有直觀(guan)反(fan)映(ying)圖像(xiang)質(zhi)量(liang)的(de)(de)功能(neng)，加(jia)之全1920*1080分(fen)辨率對于數(shu)字告示領域的(de)(de)顯(xian)(xian)示設(she)備的(de)(de)選用，液晶(jing)拼接(jie)屏是優先選擇的(de)(de)拼接(jie)屏，專(zhuan)業拼接(jie)屏分(fen)辨率是根據顯(xian)(xian)示輸出(chu)自(zi)動調整分(fen)辨率（不管(guan)橫豎都(dou)可(ke)以支持）；其(qi)高可(ke)靠性和高清(qing)楚(chu)顯(xian)(xian)示能(neng)力將保證(zheng)您可(ke)以將記錄編輯好(hao)的(de)(de)高清(qing)楚(chu)影音，視頻信號完整的(de)(de)顯(xian)(xian)示在觀(guan)看(kan)者眼前。
反之，液(ye)晶電(dian)(dian)(dian)視(shi)只(zhi)(zhi)支持說明書(shu)中(zhong)規定的(de)幾(ji)(ji)種(zhong)電(dian)(dian)(dian)視(shi)常(chang)用(yong)(yong)(yong)(yong)分(fen)辨(bian)率(lv)。由于民(min)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)視(shi)信號的(de)分(fen)辨(bian)率(lv)只(zhi)(zhi)有幾(ji)(ji)種(zhong)，電(dian)(dian)(dian)視(shi)LCD只(zhi)(zhi)要根據民(min)用(yong)(yong)(yong)(yong)用(yong)(yong)(yong)(yong)戶使用(yong)(yong)(yong)(yong)的(de)常(chang)用(yong)(yong)(yong)(yong)幾(ji)(ji)個分(fen)辨(bian)率(lv)進行效果處理，特殊分(fen)辨(bian)率(lv)會導致花(hua)屏。
三、色彩還原度
假如說清楚度(du)(du)(du)主(zhu)要是由視(shi)頻(pin)通道的(de)(de)幅頻(pin)特(te)性決定(ding)的(de)(de)話(hua)，還原(yuan)(yuan)度(du)(du)(du)則主(zhu)要由液晶拼接(jie)屏(ping)中有紅(R)、綠(lv)(G)、藍(lan)(B)三基(ji)色(se)(se)(se)(se)的(de)(de)色(se)(se)(se)(se)度(du)(du)(du)信號和亮度(du)(du)(du)信號的(de)(de)相位(wei)所決定(ding)。由于液晶拼接(jie)屏(ping)所觀察的(de)(de)通常為靜態圖(tu)像，因而(er)對拼接(jie)屏(ping)色(se)(se)(se)(se)彩(cai)還原(yuan)(yuan)度(du)(du)(du)的(de)(de)要求比電(dian)視(shi)機更高，故(gu)專業拼接(jie)屏(ping)的(de)(de)視(shi)放通道在(zai)亮度(du)(du)(du)、色(se)(se)(se)(se)度(du)(du)(du)處理(li)和R、G、B處理(li)上應(ying)具備(bei)的(de)(de)補償(chang)電(dian)路(lu)(lu)和延遲(chi)電(dian)路(lu)(lu)，以確保(bao)亮/色(se)(se)(se)(se)信號和R、G、B信號的(de)(de)相位(wei)同步(bu)。
反(fan)之，液晶電視由于(yu)使用(yong)環境要求(qiu)所至，圖象(xiang)是經過潤(run)色處理后進行顯(xian)示。不能完全真實反(fan)映實際(ji)效果。
四、機器材料的使用
由于(yu)使(shi)用(yong)環(huan)境的要(yao)求，液晶(jing)電視機(ji)器外(wai)(wai)殼材質部分采用(yong)金屬質地。且內部板(ban)線都是產業化設(she)(she)計(ji)，不輕易老化；節能(neng)環(huan)保理念的體現：低能(neng)耗設(she)(she)計(ji)；環(huan)保材料使(shi)用(yong)。規整的外(wai)(wai)觀，便于(yu)拼接，組合安裝(zhuang)等產業需要(yao)。
反之(zhi)，液晶電(dian)視整機外(wai)(wai)殼全部為非(fei)(fei)金屬(shu)材質設計。內部板(ban)線(xian)是采(cai)用(yong)民用(yong)設計，長(chang)時間開機輕(qing)易造成機件老化。另外(wai)(wai)民用(yong)電(dian)視外(wai)(wai)觀(guan)(guan)多(duo)是非(fei)(fei)規則外(wai)(wai)觀(guan)(guan)，附帶數(shu)字標(biao)牌拼接屏系統、外(wai)(wai)觀(guan)(guan)圓弧系統等作為聽覺和視覺的附屬(shu)設施，施工起來整體美觀(guan)(guan)和效果都會大打(da)折(zhe)扣。
五、端口
液晶(jing)拼接屏多采用產業端口(kou)(kou)(kou)例(li)如RGBBNC的(de)(de)色差帶自鎖機構的(de)(de)接口(kou)(kou)(kou)和專業的(de)(de)DVI-D視(shi)頻接口(kou)(kou)(kou)；
反之(zhi)，液晶(jing)電視則(ze)沒有(you)BNC自鎖色差輸進接(jie)(jie)口和DVI-D接(jie)(jie)口；
六、控制接口
液(ye)晶拼(pin)接屏可(ke)采用S232串口控(kong)制，開(kai)(kai)放的控(kong)制口令(ling)多達200多條，適應(ying)各(ge)種產業環境(jing)。方便多拼(pin)接屏使用時，不用通過遠控(kong)器(qi)就可(ke)以控(kong)制所有顯示設備(bei)，并能夠(gou)輔助，定時開(kai)(kai)機，延時開(kai)(kai)機、機器(qi)自檢(jian)等(deng)各(ge)種產業要求。
反(fan)之，液晶電視也可采用S232串口控(kong)(kong)(kong)制(zhi)。但只(zhi)能實(shi)現遠控(kong)(kong)(kong)器所具備的控(kong)(kong)(kong)制(zhi)指令。并(bing)不能實(shi)現產(chan)業控(kong)(kong)(kong)制(zhi)。
七、無風扇架構
液(ye)晶(jing)拼接屏在設計上(shang)采用無(wu)機械排風扇(shan)來(lai)保持(chi)空氣流通和散熱(re)，從而避免由(you)(you)于機械排風扇(shan)導致的灰塵和風扇(shan)噪音題目，當內部溫度由(you)(you)于不明原因而升高時，液(ye)晶(jing)拼接屏自動控制背(bei)光(guang)系(xi)統將溫度保持(chi)在比較高工(gong)作溫度之(zhi)下。
反之(zhi)，液晶電視(shi)由于應用(yong)的環境所致，對此(ci)無嚴格要求。
八．亮度
普(pu)通的液晶電(dian)視亮度只有200cd/m2,而拼(pin)接拼(pin)可(ke)以達到450cd/m2或者700cd/m2
