一、整機穩定性(包括使用時間、抗干擾等)
液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)在(zai)構成數(shu)字告示(shi)系統(tong)時(shi),通(tong)(tong)常需要(yao)天(tian)天(tian)24小(xiao)時(shi),每年(nian)365天(tian)連續無(wu)中(zhong)斷的(de)(de)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)使用(yong)(yong)(而電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)(ji)通(tong)(tong)常天(tian)天(tian)僅(jin)工(gong)作(zuo)幾小(xiao)時(shi)),并且某些拼(pin)接(jie)屏(ping)(ping)(ping)(ping)的(de)(de)應用(yong)(yong)環境(jing)可能較為惡劣,這就要(yao)求液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)的(de)(de)可靠(kao)性(xing)和穩(wen)定(ding)性(xing)更高(gao)。與電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)(ji)相比(bi)而言,在(zai)設計上(shang)(shang),液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流、功(gong)耗、溫度(du)(du)(du)及抗電(dian)(dian)(dian)(dian)(dian)(dian)干(gan)擾(rao)、電(dian)(dian)(dian)(dian)(dian)(dian)沖擊的(de)(de)能力和裕(yu)度(du)(du)(du)以(yi)及均勻無(wu)故障使用(yong)(yong)時(shi)間均要(yao)遠大于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)(ji),同(tong)時(shi)液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)還必須使用(yong)(yong)全(quan)屏(ping)(ping)(ping)(ping)蔽金屬(shu)外殼確保(bao)電(dian)(dian)(dian)(dian)(dian)(dian)磁兼(jian)容(rong)和干(gan)擾(rao)性(xing)能;在(zai)元(yuan)(yuan)器(qi)(qi)件的(de)(de)選(xuan)型上(shang)(shang),液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)使用(yong)(yong)的(de)(de)元(yuan)(yuan)器(qi)(qi)件的(de)(de)耐壓、電(dian)(dian)(dian)(dian)(dian)(dian)流、溫度(du)(du)(du)、濕(shi)度(du)(du)(du)等各方(fang)面特性(xing)都要(yao)高(gao)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)(ji)使用(yong)(yong)的(de)(de)元(yuan)(yuan)器(qi)(qi)件;而在(zai)安(an)裝、調試尤其(qi)是(shi)元(yuan)(yuan)器(qi)(qi)件和整機(ji)(ji)(ji)(ji)老(lao)化的(de)(de)工(gong)藝要(yao)求上(shang)(shang),液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)的(de)(de)要(yao)求也更高(gao),電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)(ji)制造時(shi)整機(ji)(ji)(ji)(ji)老(lao)化通(tong)(tong)常是(shi)在(zai)流水線上(shang)(shang)常溫通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)8小(xiao)時(shi)左(zuo)右,而液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)的(de)(de)整機(ji)(ji)(ji)(ji)老(lao)化則(ze)需要(yao)在(zai)高(gao)溫、高(gao)濕(shi)密(mi)閉環境(jing)的(de)(de)老(lao)化流水線上(shang)(shang)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)老(lao)化24小(xiao)時(shi)以(yi)上(shang)(shang),以(yi)確保(bao)整機(ji)(ji)(ji)(ji)的(de)(de)穩(wen)定(ding)性(xing)。普通(tong)(tong)的(de)(de)液(ye)(ye)(ye)(ye)晶(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)使用(yong)(yong)的(de)(de)LCD液(ye)(ye)(ye)(ye)晶(jing)(jing)屏(ping)(ping)(ping)(ping)其(qi)背光(guang)源的(de)(de)使用(yong)(yong)壽命為1萬至3萬小(xiao)時(shi),而液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)背光(guang)源的(de)(de)使用(yong)(yong)壽命均可達6-7萬小(xiao)時(shi)以(yi)上(shang)(shang)。液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接(jie)屏(ping)(ping)(ping)(ping)廠家
二、圖像清楚度
液晶拼(pin)(pin)接顯(xian)示(shi)(shi)用(yong)具(ju)有直觀(guan)反映(ying)圖像質(zhi)量的(de)功能,加之全1920*1080分(fen)辨(bian)率對(dui)于數字告示(shi)(shi)領域的(de)顯(xian)示(shi)(shi)設備(bei)的(de)選(xuan)用(yong),液晶拼(pin)(pin)接屏是優先選(xuan)擇(ze)的(de)拼(pin)(pin)接屏,專業(ye)拼(pin)(pin)接屏分(fen)辨(bian)率是根據顯(xian)示(shi)(shi)輸出(chu)自動調(diao)整分(fen)辨(bian)率(不管橫(heng)豎都可以(yi)支持);其高可靠性和高清楚顯(xian)示(shi)(shi)能力將(jiang)(jiang)保證(zheng)您可以(yi)將(jiang)(jiang)記錄編輯好的(de)高清楚影音(yin),視頻(pin)信號完整的(de)顯(xian)示(shi)(shi)在觀(guan)看者眼前。
反之,液晶電視(shi)只支(zhi)持說明書中規定的(de)幾種電視(shi)常用分(fen)辨(bian)率(lv)(lv)。由于民(min)用電視(shi)信號的(de)分(fen)辨(bian)率(lv)(lv)只有幾種,電視(shi)LCD只要根據民(min)用用戶使用的(de)常用幾個分(fen)辨(bian)率(lv)(lv)進(jin)行效果處理,特殊分(fen)辨(bian)率(lv)(lv)會(hui)導致花屏。
三、色彩還原度
假如(ru)說(shuo)清(qing)楚度(du)主(zhu)要(yao)(yao)是(shi)由視頻通道的(de)(de)幅頻特性(xing)決定的(de)(de)話,還原度(du)則(ze)主(zhu)要(yao)(yao)由液(ye)晶(jing)拼(pin)(pin)接(jie)屏中有紅(R)、綠(G)、藍(B)三基(ji)色(se)(se)的(de)(de)色(se)(se)度(du)信(xin)號和(he)亮度(du)信(xin)號的(de)(de)相(xiang)位(wei)所(suo)決定。由于液(ye)晶(jing)拼(pin)(pin)接(jie)屏所(suo)觀察的(de)(de)通常為靜(jing)態圖像,因而對拼(pin)(pin)接(jie)屏色(se)(se)彩還原度(du)的(de)(de)要(yao)(yao)求比(bi)電視機更高,故(gu)專業拼(pin)(pin)接(jie)屏的(de)(de)視放(fang)通道在亮度(du)、色(se)(se)度(du)處理和(he)R、G、B處理上(shang)應具備的(de)(de)補償電路和(he)延遲電路,以確保亮/色(se)(se)信(xin)號和(he)R、G、B信(xin)號的(de)(de)相(xiang)位(wei)同步。
反(fan)之,液晶電視由于使用(yong)環境要求所至,圖象(xiang)是(shi)經(jing)過潤色(se)處理后進行(xing)顯示。不能完全真實反(fan)映實際效果。
四、機器材料的使用
由于使(shi)用環(huan)境的要求,液晶電視機器(qi)外(wai)殼材(cai)質(zhi)部(bu)(bu)分采用金屬質(zhi)地。且(qie)內部(bu)(bu)板線都是(shi)產業化設(she)計,不(bu)輕易老化;節能環(huan)保(bao)理念的體現(xian):低能耗設(she)計;環(huan)保(bao)材(cai)料使(shi)用。規(gui)整的外(wai)觀(guan),便(bian)于拼接,組合安裝等(deng)產業需(xu)要。
反之,液晶電視(shi)整(zheng)機(ji)外(wai)殼(ke)全部(bu)為(wei)非(fei)金屬(shu)材(cai)質設(she)計。內部(bu)板線是采(cai)用(yong)民用(yong)設(she)計,長時(shi)間開機(ji)輕易造成機(ji)件老化。另外(wai)民用(yong)電視(shi)外(wai)觀(guan)(guan)多是非(fei)規則外(wai)觀(guan)(guan),附(fu)帶數字標牌拼接屏(ping)系(xi)統、外(wai)觀(guan)(guan)圓弧(hu)系(xi)統等作為(wei)聽覺(jue)和(he)視(shi)覺(jue)的(de)附(fu)屬(shu)設(she)施,施工起來整(zheng)體美觀(guan)(guan)和(he)效果都會大(da)打折扣。
五、端口
液晶拼接(jie)屏多采用(yong)產業端(duan)口(kou)(kou)例如RGBBNC的色(se)差帶自(zi)鎖機構的接(jie)口(kou)(kou)和(he)專業的DVI-D視頻(pin)接(jie)口(kou)(kou);
反之,液晶(jing)電視則沒有BNC自(zi)鎖色(se)差輸進接口和DVI-D接口;
六、控制接口
液(ye)晶拼接屏(ping)可采用S232串(chuan)口(kou)控(kong)(kong)制(zhi)(zhi),開(kai)放的控(kong)(kong)制(zhi)(zhi)口(kou)令多(duo)(duo)達200多(duo)(duo)條(tiao),適應各種產業(ye)(ye)環境。方(fang)便多(duo)(duo)拼接屏(ping)使用時(shi),不用通(tong)過遠控(kong)(kong)器(qi)就可以控(kong)(kong)制(zhi)(zhi)所(suo)有顯(xian)示(shi)設(she)備,并能夠輔助,定時(shi)開(kai)機(ji),延(yan)時(shi)開(kai)機(ji)、機(ji)器(qi)自檢(jian)等各種產業(ye)(ye)要(yao)求。
反之,液(ye)晶(jing)電視也可采用S232串口控(kong)制。但只能實現遠控(kong)器所具備(bei)的控(kong)制指令。并不能實現產業控(kong)制。
七、無風扇架構
液(ye)(ye)晶拼接屏在設計上采(cai)用無(wu)機(ji)械排風(feng)扇(shan)來保持(chi)空氣流通(tong)和散熱,從而(er)避免由于(yu)機(ji)械排風(feng)扇(shan)導致的灰塵(chen)和風(feng)扇(shan)噪音題目(mu),當(dang)內部溫度由于(yu)不明原因而(er)升高時(shi),液(ye)(ye)晶拼接屏自(zi)動控制背光系統將(jiang)溫度保持(chi)在比較高工作溫度之下。
反之(zhi),液晶電視(shi)由于(yu)應用的環境所致,對此(ci)無嚴格要求。
八.亮度
普通(tong)的(de)液晶電視亮度只有200cd/m2,而拼接拼可以達到450cd/m2或者700cd/m2
