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)接屏(ping)(ping)(ping)在(zai)(zai)構成數字告示系統(tong)時(shi)(shi),通(tong)(tong)(tong)常(chang)(chang)(chang)需要天(tian)(tian)天(tian)(tian)24小(xiao)時(shi)(shi),每年365天(tian)(tian)連續無中(zhong)斷的(de)(de)(de)(de)(de)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)使用(yong)(yong)(yong)(而電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)通(tong)(tong)(tong)常(chang)(chang)(chang)天(tian)(tian)天(tian)(tian)僅工(gong)作幾(ji)小(xiao)時(shi)(shi)),并且某些拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)應(ying)用(yong)(yong)(yong)環境可(ke)能較為(wei)惡劣,這(zhe)就(jiu)要求(qiu)液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)可(ke)靠性(xing)和穩(wen)(wen)定(ding)性(xing)更高(gao)。與電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)相比而言,在(zai)(zai)設計上,液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)、功耗、溫度(du)及抗電(dian)(dian)(dian)(dian)(dian)干(gan)擾(rao)、電(dian)(dian)(dian)(dian)(dian)沖擊(ji)的(de)(de)(de)(de)(de)能力(li)和裕度(du)以及均勻無故障使用(yong)(yong)(yong)時(shi)(shi)間均要遠大于(yu)電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji),同時(shi)(shi)液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)還必(bi)須使用(yong)(yong)(yong)全屏(ping)(ping)(ping)蔽金屬外殼確(que)保(bao)電(dian)(dian)(dian)(dian)(dian)磁(ci)兼容和干(gan)擾(rao)性(xing)能;在(zai)(zai)元(yuan)(yuan)(yuan)器(qi)件的(de)(de)(de)(de)(de)選(xuan)型上,液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)使用(yong)(yong)(yong)的(de)(de)(de)(de)(de)元(yuan)(yuan)(yuan)器(qi)件的(de)(de)(de)(de)(de)耐壓、電(dian)(dian)(dian)(dian)(dian)流(liu)、溫度(du)、濕(shi)度(du)等各(ge)方面特(te)性(xing)都要高(gao)于(yu)電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)使用(yong)(yong)(yong)的(de)(de)(de)(de)(de)元(yuan)(yuan)(yuan)器(qi)件;而在(zai)(zai)安裝、調試尤其是元(yuan)(yuan)(yuan)器(qi)件和整(zheng)機(ji)(ji)老化的(de)(de)(de)(de)(de)工(gong)藝要求(qiu)上,液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)要求(qiu)也更高(gao),電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)制造時(shi)(shi)整(zheng)機(ji)(ji)老化通(tong)(tong)(tong)常(chang)(chang)(chang)是在(zai)(zai)流(liu)水線上常(chang)(chang)(chang)溫通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)8小(xiao)時(shi)(shi)左右,而液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)整(zheng)機(ji)(ji)老化則需要在(zai)(zai)高(gao)溫、高(gao)濕(shi)密閉環境的(de)(de)(de)(de)(de)老化流(liu)水線上通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)老化24小(xiao)時(shi)(shi)以上,以確(que)保(bao)整(zheng)機(ji)(ji)的(de)(de)(de)(de)(de)穩(wen)(wen)定(ding)性(xing)。普通(tong)(tong)(tong)的(de)(de)(de)(de)(de)液(ye)(ye)(ye)(ye)晶(jing)(jing)電(dian)(dian)(dian)(dian)(dian)視使用(yong)(yong)(yong)的(de)(de)(de)(de)(de)LCD液(ye)(ye)(ye)(ye)晶(jing)(jing)屏(ping)(ping)(ping)其背光(guang)源的(de)(de)(de)(de)(de)使用(yong)(yong)(yong)壽命為(wei)1萬(wan)至3萬(wan)小(xiao)時(shi)(shi),而液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)背光(guang)源的(de)(de)(de)(de)(de)使用(yong)(yong)(yong)壽命均可(ke)達6-7萬(wan)小(xiao)時(shi)(shi)以上。液(ye)(ye)(ye)(ye)晶(jing)(jing)拼(pin)接屏(ping)(ping)(ping)廠家
二、圖像清楚度
液(ye)晶拼接(jie)顯(xian)(xian)示(shi)(shi)用具有直觀反映圖像質量的(de)(de)功(gong)能,加之全(quan)1920*1080分辨率(lv)對于(yu)數字告示(shi)(shi)領域的(de)(de)顯(xian)(xian)示(shi)(shi)設備的(de)(de)選(xuan)用,液(ye)晶拼接(jie)屏是優(you)先(xian)選(xuan)擇的(de)(de)拼接(jie)屏,專業拼接(jie)屏分辨率(lv)是根據顯(xian)(xian)示(shi)(shi)輸出自動調整(zheng)分辨率(lv)(不管橫豎(shu)都可以支持);其(qi)高(gao)可靠性和高(gao)清楚顯(xian)(xian)示(shi)(shi)能力將保證(zheng)您可以將記錄編輯好的(de)(de)高(gao)清楚影音,視頻信(xin)號完整(zheng)的(de)(de)顯(xian)(xian)示(shi)(shi)在(zai)觀看(kan)者眼前。
反之,液晶電視(shi)(shi)只(zhi)支持說明書中規定的幾種(zhong)電視(shi)(shi)常(chang)用(yong)(yong)分(fen)辨(bian)(bian)率(lv)。由于民用(yong)(yong)電視(shi)(shi)信號的分(fen)辨(bian)(bian)率(lv)只(zhi)有幾種(zhong),電視(shi)(shi)LCD只(zhi)要(yao)根據民用(yong)(yong)用(yong)(yong)戶使(shi)用(yong)(yong)的常(chang)用(yong)(yong)幾個分(fen)辨(bian)(bian)率(lv)進行效果處理,特殊分(fen)辨(bian)(bian)率(lv)會導致花(hua)屏(ping)。
三、色彩還原度
假(jia)如說清楚(chu)度(du)主要(yao)(yao)是由視(shi)頻通(tong)道的(de)幅頻特性決(jue)定(ding)的(de)話,還原度(du)則主要(yao)(yao)由液晶拼(pin)接屏中有(you)紅(R)、綠(G)、藍(B)三(san)基色(se)(se)的(de)色(se)(se)度(du)信號(hao)和(he)(he)亮(liang)度(du)信號(hao)的(de)相(xiang)位(wei)所(suo)決(jue)定(ding)。由于液晶拼(pin)接屏所(suo)觀察的(de)通(tong)常為靜態(tai)圖(tu)像(xiang),因而對拼(pin)接屏色(se)(se)彩還原度(du)的(de)要(yao)(yao)求比電視(shi)機(ji)更(geng)高,故專(zhuan)業拼(pin)接屏的(de)視(shi)放通(tong)道在亮(liang)度(du)、色(se)(se)度(du)處理和(he)(he)R、G、B處理上應(ying)具備的(de)補(bu)償電路(lu)和(he)(he)延遲電路(lu),以(yi)確保亮(liang)/色(se)(se)信號(hao)和(he)(he)R、G、B信號(hao)的(de)相(xiang)位(wei)同(tong)步。
反之,液晶電(dian)視(shi)由于(yu)使用(yong)環境(jing)要求(qiu)所至,圖象是經過潤色處理后進行顯(xian)示。不能完(wan)全真實反映實際(ji)效果。
四、機器材料的使用
由(you)于使(shi)用(yong)(yong)環(huan)境的要求(qiu),液晶電視機器外殼材質(zhi)部(bu)分采(cai)用(yong)(yong)金(jin)屬質(zhi)地。且內部(bu)板線都是(shi)產業化(hua)設(she)計,不輕易老化(hua);節能環(huan)保理(li)念的體現:低能耗(hao)設(she)計;環(huan)保材料(liao)使(shi)用(yong)(yong)。規整的外觀,便于拼接,組合安(an)裝等產業需要。
反(fan)之(zhi),液晶(jing)電視整(zheng)機外(wai)殼全部為非金(jin)屬(shu)材質設計。內部板線是(shi)采用民(min)用設計,長時間開(kai)機輕易造成機件(jian)老化。另外(wai)民(min)用電視外(wai)觀(guan)(guan)多是(shi)非規則外(wai)觀(guan)(guan),附帶(dai)數字標牌拼接屏系(xi)統、外(wai)觀(guan)(guan)圓弧系(xi)統等作(zuo)為聽覺和視覺的附屬(shu)設施,施工起來整(zheng)體美觀(guan)(guan)和效果都會(hui)大打折扣。
五、端口
液晶(jing)拼接屏多采用產業端口例如RGBBNC的(de)色差帶自鎖機(ji)構的(de)接口和專業的(de)DVI-D視頻接口;
反(fan)之(zhi),液晶(jing)電(dian)視則沒有BNC自(zi)鎖色(se)差輸進接口(kou)和DVI-D接口(kou);
六、控制接口
液晶拼接屏(ping)可(ke)采(cai)用S232串(chuan)口控制,開放的(de)控制口令多達200多條,適應(ying)各種產業環(huan)境。方便多拼接屏(ping)使用時(shi),不用通過遠控器(qi)就可(ke)以控制所有(you)顯示設備,并能夠輔(fu)助,定時(shi)開機,延時(shi)開機、機器(qi)自檢(jian)等(deng)各種產業要求。
反之,液晶電視也(ye)可采用S232串口控(kong)(kong)制。但只能實(shi)現遠控(kong)(kong)器所具備的控(kong)(kong)制指令。并(bing)不能實(shi)現產業(ye)控(kong)(kong)制。
七、無風扇架構
液晶拼接(jie)屏在(zai)設(she)計(ji)上采用無機(ji)(ji)械(xie)排風扇來保持空氣流通和(he)散(san)熱,從而(er)避免由(you)于(yu)機(ji)(ji)械(xie)排風扇導致的(de)灰塵和(he)風扇噪(zao)音題目,當內部溫(wen)度由(you)于(yu)不明原因而(er)升高時,液晶拼接(jie)屏自動控制背光系(xi)統(tong)將溫(wen)度保持在(zai)比較高工作溫(wen)度之下。
反之(zhi),液晶電視由(you)于應用的環(huan)境所致,對此無嚴格要求。
八.亮度
普通的(de)液晶電視亮度只有(you)200cd/m2,而拼接拼可以(yi)達到450cd/m2或(huo)者(zhe)700cd/m2
