一、整機穩定性(包括使用時間、抗干擾等)
液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)在(zai)構成數字告(gao)示系統(tong)時(shi)(shi),通(tong)(tong)常(chang)需要(yao)(yao)天(tian)(tian)天(tian)(tian)24小(xiao)時(shi)(shi),每(mei)年365天(tian)(tian)連續無中斷的(de)(de)(de)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)使(shi)(shi)(shi)(shi)用(yong)(而(er)(er)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機通(tong)(tong)常(chang)天(tian)(tian)天(tian)(tian)僅工(gong)作幾(ji)小(xiao)時(shi)(shi)),并(bing)且某(mou)些拼(pin)(pin)(pin)接(jie)屏(ping)(ping)的(de)(de)(de)應用(yong)環境可能(neng)較(jiao)為(wei)惡劣,這就要(yao)(yao)求液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)的(de)(de)(de)可靠性(xing)(xing)和(he)(he)穩定性(xing)(xing)更(geng)高(gao)(gao)。與電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機相比(bi)而(er)(er)言(yan),在(zai)設計上(shang),液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)、功耗、溫(wen)(wen)度(du)及(ji)抗(kang)電(dian)(dian)(dian)(dian)(dian)干擾、電(dian)(dian)(dian)(dian)(dian)沖擊(ji)的(de)(de)(de)能(neng)力和(he)(he)裕度(du)以(yi)及(ji)均(jun)勻無故障使(shi)(shi)(shi)(shi)用(yong)時(shi)(shi)間均(jun)要(yao)(yao)遠大于電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機,同(tong)時(shi)(shi)液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)還(huan)必須使(shi)(shi)(shi)(shi)用(yong)全(quan)屏(ping)(ping)蔽(bi)金屬外殼確(que)保(bao)電(dian)(dian)(dian)(dian)(dian)磁兼容和(he)(he)干擾性(xing)(xing)能(neng);在(zai)元器件(jian)的(de)(de)(de)選型上(shang),液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)使(shi)(shi)(shi)(shi)用(yong)的(de)(de)(de)元器件(jian)的(de)(de)(de)耐壓(ya)、電(dian)(dian)(dian)(dian)(dian)流(liu)、溫(wen)(wen)度(du)、濕度(du)等(deng)各方面特性(xing)(xing)都要(yao)(yao)高(gao)(gao)于電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機使(shi)(shi)(shi)(shi)用(yong)的(de)(de)(de)元器件(jian);而(er)(er)在(zai)安裝、調試尤其是元器件(jian)和(he)(he)整(zheng)機老(lao)(lao)化(hua)(hua)的(de)(de)(de)工(gong)藝(yi)要(yao)(yao)求上(shang),液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)的(de)(de)(de)要(yao)(yao)求也更(geng)高(gao)(gao),電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機制造時(shi)(shi)整(zheng)機老(lao)(lao)化(hua)(hua)通(tong)(tong)常(chang)是在(zai)流(liu)水線上(shang)常(chang)溫(wen)(wen)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)8小(xiao)時(shi)(shi)左(zuo)右,而(er)(er)液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)的(de)(de)(de)整(zheng)機老(lao)(lao)化(hua)(hua)則需要(yao)(yao)在(zai)高(gao)(gao)溫(wen)(wen)、高(gao)(gao)濕密(mi)閉環境的(de)(de)(de)老(lao)(lao)化(hua)(hua)流(liu)水線上(shang)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)老(lao)(lao)化(hua)(hua)24小(xiao)時(shi)(shi)以(yi)上(shang),以(yi)確(que)保(bao)整(zheng)機的(de)(de)(de)穩定性(xing)(xing)。普(pu)通(tong)(tong)的(de)(de)(de)液(ye)(ye)(ye)(ye)晶電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)使(shi)(shi)(shi)(shi)用(yong)的(de)(de)(de)LCD液(ye)(ye)(ye)(ye)晶屏(ping)(ping)其背(bei)光(guang)源的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)壽(shou)命為(wei)1萬至3萬小(xiao)時(shi)(shi),而(er)(er)液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)背(bei)光(guang)源的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)壽(shou)命均(jun)可達6-7萬小(xiao)時(shi)(shi)以(yi)上(shang)。液(ye)(ye)(ye)(ye)晶拼(pin)(pin)(pin)接(jie)屏(ping)(ping)廠家
二、圖像清楚度
液(ye)晶(jing)(jing)拼(pin)接(jie)顯(xian)示(shi)用(yong)具有直觀反映圖(tu)像質量的功能(neng),加之全1920*1080分(fen)辨(bian)率(lv)對于(yu)數字(zi)告示(shi)領域(yu)的顯(xian)示(shi)設備(bei)的選用(yong),液(ye)晶(jing)(jing)拼(pin)接(jie)屏是優先選擇的拼(pin)接(jie)屏,專業拼(pin)接(jie)屏分(fen)辨(bian)率(lv)是根據(ju)顯(xian)示(shi)輸出自動調整分(fen)辨(bian)率(lv)(不管橫(heng)豎都可以支持);其高(gao)可靠性和(he)高(gao)清楚(chu)顯(xian)示(shi)能(neng)力將保證您可以將記錄(lu)編輯好的高(gao)清楚(chu)影音,視頻信號完(wan)整的顯(xian)示(shi)在觀看者眼前。
反之,液晶電(dian)視只(zhi)支(zhi)持說明書中規定的幾(ji)種電(dian)視常(chang)用(yong)(yong)(yong)分(fen)辨(bian)(bian)率。由于民用(yong)(yong)(yong)電(dian)視信號的分(fen)辨(bian)(bian)率只(zhi)有幾(ji)種,電(dian)視LCD只(zhi)要(yao)根(gen)據民用(yong)(yong)(yong)用(yong)(yong)(yong)戶使用(yong)(yong)(yong)的常(chang)用(yong)(yong)(yong)幾(ji)個分(fen)辨(bian)(bian)率進行效果處理,特(te)殊(shu)分(fen)辨(bian)(bian)率會導致花屏。
三、色彩還原度
假如說清楚度(du)主要(yao)是由視頻(pin)通(tong)道(dao)的幅(fu)頻(pin)特性(xing)決(jue)定的話,還(huan)(huan)原度(du)則主要(yao)由液晶拼(pin)接(jie)屏(ping)中(zhong)有紅(hong)(R)、綠(G)、藍(B)三基(ji)色的色度(du)信號(hao)和(he)亮度(du)信號(hao)的相位(wei)(wei)所(suo)決(jue)定。由于液晶拼(pin)接(jie)屏(ping)所(suo)觀察的通(tong)常為(wei)靜態圖像,因而對拼(pin)接(jie)屏(ping)色彩(cai)還(huan)(huan)原度(du)的要(yao)求比電視機(ji)更高,故專業(ye)拼(pin)接(jie)屏(ping)的視放通(tong)道(dao)在亮度(du)、色度(du)處(chu)理(li)和(he)R、G、B處(chu)理(li)上應具備(bei)的補償電路和(he)延(yan)遲(chi)電路,以確保亮/色信號(hao)和(he)R、G、B信號(hao)的相位(wei)(wei)同步。
反(fan)之,液晶電視由于(yu)使用環境要(yao)求所至,圖(tu)象是經過潤色(se)處理(li)后進行顯示。不能完(wan)全真實反(fan)映實際(ji)效果。
四、機器材料的使用
由于使用環(huan)境的要(yao)求,液晶(jing)電視(shi)機器外殼材質部(bu)分(fen)采用金(jin)屬(shu)質地。且內部(bu)板線都是產業(ye)化設計(ji)(ji),不輕易老化;節能環(huan)保(bao)理念(nian)的體現:低能耗設計(ji)(ji);環(huan)保(bao)材料使用。規整的外觀,便于拼接,組合安裝等產業(ye)需要(yao)。
反之,液晶電(dian)視整(zheng)機外(wai)(wai)殼全部(bu)為非金(jin)屬材(cai)質設(she)計(ji)(ji)。內部(bu)板線(xian)是(shi)采用民用設(she)計(ji)(ji),長時間(jian)開機輕(qing)易造成機件老化。另外(wai)(wai)民用電(dian)視外(wai)(wai)觀(guan)多是(shi)非規則外(wai)(wai)觀(guan),附帶數字(zi)標牌(pai)拼接(jie)屏系統、外(wai)(wai)觀(guan)圓弧系統等作為聽覺(jue)和視覺(jue)的附屬設(she)施(shi),施(shi)工起來整(zheng)體美觀(guan)和效果都會大打折(zhe)扣。
五、端口
液晶拼接屏多采用(yong)產(chan)業端(duan)口(kou)例(li)如RGBBNC的色差(cha)帶自鎖機(ji)構的接口(kou)和專業的DVI-D視(shi)頻(pin)接口(kou);
反之,液晶電視則沒(mei)有BNC自(zi)鎖色差(cha)輸進(jin)接口和DVI-D接口;
六、控制接口
液晶拼接屏可采用(yong)S232串口(kou)控(kong)制(zhi),開(kai)(kai)(kai)放的控(kong)制(zhi)口(kou)令多達(da)200多條,適應各種產(chan)業環境。方便多拼接屏使用(yong)時,不用(yong)通(tong)過遠控(kong)器就(jiu)可以控(kong)制(zhi)所有顯示設備,并能夠輔(fu)助,定時開(kai)(kai)(kai)機,延時開(kai)(kai)(kai)機、機器自檢等各種產(chan)業要求。
反之,液晶電視也可采(cai)用(yong)S232串口控制(zhi)。但只能實現遠控器所(suo)具(ju)備的控制(zhi)指令。并不能實現產(chan)業(ye)控制(zhi)。
七、無風扇架構
液晶拼接(jie)屏在設計上采用無機械排風扇(shan)(shan)來保持空氣流通和散熱,從而避免(mian)由于機械排風扇(shan)(shan)導致的(de)灰塵和風扇(shan)(shan)噪(zao)音題目,當內部溫度由于不(bu)明原(yuan)因而升高時,液晶拼接(jie)屏自動控制背光系統將溫度保持在比較高工作溫度之下。
反之,液晶電視由于應用的(de)環境(jing)所(suo)致(zhi),對此無(wu)嚴格要求。
八.亮度
普通(tong)的液晶電視(shi)亮度(du)只有(you)200cd/m2,而拼(pin)接(jie)拼(pin)可(ke)以達到(dao)450cd/m2或者700cd/m2
