一、整機穩定性(包括使用時間、抗干擾等)
液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)在(zai)構(gou)成數字告示系統時(shi)(shi),通(tong)(tong)(tong)常需(xu)要(yao)(yao)天(tian)天(tian)24小(xiao)時(shi)(shi),每年365天(tian)連(lian)續無中(zhong)斷的(de)(de)(de)(de)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)使(shi)用(yong)(yong)(而(er)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)通(tong)(tong)(tong)常天(tian)天(tian)僅(jin)工作(zuo)幾小(xiao)時(shi)(shi)),并且某(mou)些(xie)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)應用(yong)(yong)環境可(ke)能(neng)較為惡(e)劣,這就要(yao)(yao)求液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)可(ke)靠性(xing)(xing)(xing)和穩定性(xing)(xing)(xing)更高(gao)(gao)(gao)。與(yu)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)相(xiang)比而(er)言,在(zai)設計上(shang),液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)、功耗、溫度及抗電(dian)(dian)(dian)(dian)干擾(rao)、電(dian)(dian)(dian)(dian)沖擊的(de)(de)(de)(de)能(neng)力和裕度以(yi)及均勻無故(gu)障使(shi)用(yong)(yong)時(shi)(shi)間均要(yao)(yao)遠大于(yu)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji),同時(shi)(shi)液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)還(huan)必須使(shi)用(yong)(yong)全屏(ping)(ping)蔽金屬外殼確保(bao)電(dian)(dian)(dian)(dian)磁兼容和干擾(rao)性(xing)(xing)(xing)能(neng);在(zai)元(yuan)器(qi)件(jian)的(de)(de)(de)(de)選(xuan)型上(shang),液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)使(shi)用(yong)(yong)的(de)(de)(de)(de)元(yuan)器(qi)件(jian)的(de)(de)(de)(de)耐壓、電(dian)(dian)(dian)(dian)流(liu)、溫度、濕(shi)度等各方面(mian)特性(xing)(xing)(xing)都要(yao)(yao)高(gao)(gao)(gao)于(yu)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)使(shi)用(yong)(yong)的(de)(de)(de)(de)元(yuan)器(qi)件(jian);而(er)在(zai)安裝、調(diao)試尤其是(shi)元(yuan)器(qi)件(jian)和整機(ji)(ji)(ji)老(lao)化(hua)(hua)(hua)的(de)(de)(de)(de)工藝要(yao)(yao)求上(shang),液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)要(yao)(yao)求也更高(gao)(gao)(gao),電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)制造時(shi)(shi)整機(ji)(ji)(ji)老(lao)化(hua)(hua)(hua)通(tong)(tong)(tong)常是(shi)在(zai)流(liu)水線上(shang)常溫通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)8小(xiao)時(shi)(shi)左右,而(er)液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)整機(ji)(ji)(ji)老(lao)化(hua)(hua)(hua)則需(xu)要(yao)(yao)在(zai)高(gao)(gao)(gao)溫、高(gao)(gao)(gao)濕(shi)密閉環境的(de)(de)(de)(de)老(lao)化(hua)(hua)(hua)流(liu)水線上(shang)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)老(lao)化(hua)(hua)(hua)24小(xiao)時(shi)(shi)以(yi)上(shang),以(yi)確保(bao)整機(ji)(ji)(ji)的(de)(de)(de)(de)穩定性(xing)(xing)(xing)。普(pu)通(tong)(tong)(tong)的(de)(de)(de)(de)液晶(jing)(jing)(jing)電(dian)(dian)(dian)(dian)視(shi)(shi)使(shi)用(yong)(yong)的(de)(de)(de)(de)LCD液晶(jing)(jing)(jing)屏(ping)(ping)其背(bei)光源的(de)(de)(de)(de)使(shi)用(yong)(yong)壽命(ming)為1萬至3萬小(xiao)時(shi)(shi),而(er)液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)背(bei)光源的(de)(de)(de)(de)使(shi)用(yong)(yong)壽命(ming)均可(ke)達6-7萬小(xiao)時(shi)(shi)以(yi)上(shang)。液晶(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)屏(ping)(ping)廠家
二、圖像清楚度
液(ye)晶(jing)拼(pin)接顯(xian)示(shi)(shi)用具有直觀反映(ying)圖像質量(liang)的功能,加之全1920*1080分辨(bian)率對于數(shu)字告示(shi)(shi)領域的顯(xian)示(shi)(shi)設備(bei)的選用,液(ye)晶(jing)拼(pin)接屏(ping)是(shi)優(you)先選擇的拼(pin)接屏(ping),專業拼(pin)接屏(ping)分辨(bian)率是(shi)根據顯(xian)示(shi)(shi)輸(shu)出(chu)自動調整(zheng)分辨(bian)率(不管橫豎(shu)都可以支持);其高可靠性和高清楚(chu)顯(xian)示(shi)(shi)能力將(jiang)保證您可以將(jiang)記錄編輯(ji)好(hao)的高清楚(chu)影音,視頻信號(hao)完整(zheng)的顯(xian)示(shi)(shi)在觀看者(zhe)眼前。
反(fan)之,液晶電(dian)視(shi)只(zhi)支持(chi)說明書中規(gui)定的幾(ji)種電(dian)視(shi)常用(yong)分(fen)(fen)(fen)辨(bian)率(lv)。由(you)于民(min)(min)用(yong)電(dian)視(shi)信號(hao)的分(fen)(fen)(fen)辨(bian)率(lv)只(zhi)有幾(ji)種,電(dian)視(shi)LCD只(zhi)要根(gen)據(ju)民(min)(min)用(yong)用(yong)戶使用(yong)的常用(yong)幾(ji)個分(fen)(fen)(fen)辨(bian)率(lv)進行效果處理,特殊分(fen)(fen)(fen)辨(bian)率(lv)會導致花屏。
三、色彩還原度
假如(ru)說清楚度(du)主要是(shi)由視頻通(tong)(tong)道(dao)的(de)(de)幅頻特性(xing)決定的(de)(de)話,還原度(du)則(ze)主要由液(ye)晶拼(pin)接(jie)屏(ping)中有紅(R)、綠(G)、藍(lan)(B)三基色(se)的(de)(de)色(se)度(du)信(xin)號和亮(liang)度(du)信(xin)號的(de)(de)相(xiang)位所(suo)決定。由于液(ye)晶拼(pin)接(jie)屏(ping)所(suo)觀察的(de)(de)通(tong)(tong)常為靜(jing)態圖像(xiang),因而對拼(pin)接(jie)屏(ping)色(se)彩還原度(du)的(de)(de)要求(qiu)比電(dian)視機更高,故專業拼(pin)接(jie)屏(ping)的(de)(de)視放通(tong)(tong)道(dao)在亮(liang)度(du)、色(se)度(du)處理和R、G、B處理上(shang)應(ying)具備的(de)(de)補償電(dian)路(lu)和延遲(chi)電(dian)路(lu),以確保亮(liang)/色(se)信(xin)號和R、G、B信(xin)號的(de)(de)相(xiang)位同(tong)步(bu)。
反之,液晶(jing)電視由于使(shi)用環(huan)境要求所(suo)至,圖象是經過(guo)潤(run)色(se)處理(li)后進行(xing)顯示(shi)。不能完全真(zhen)實反映(ying)實際效果。
四、機器材料的使用
由于(yu)使用(yong)環(huan)境(jing)的要求,液晶電視(shi)機(ji)器外(wai)殼材質部(bu)分采用(yong)金屬質地。且(qie)內部(bu)板(ban)線都是產(chan)業化(hua)設計,不輕易老化(hua);節能環(huan)保(bao)理念的體現:低(di)能耗(hao)設計;環(huan)保(bao)材料使用(yong)。規整的外(wai)觀,便于(yu)拼(pin)接(jie),組合安(an)裝(zhuang)等(deng)產(chan)業需(xu)要。
反之,液晶電(dian)視(shi)(shi)整機(ji)外(wai)殼全部為非金(jin)屬材質設(she)計。內部板線是采用(yong)民用(yong)設(she)計,長時間開機(ji)輕(qing)易造(zao)成機(ji)件老化。另外(wai)民用(yong)電(dian)視(shi)(shi)外(wai)觀(guan)多是非規則外(wai)觀(guan),附帶數字(zi)標牌(pai)拼接(jie)屏系統、外(wai)觀(guan)圓弧(hu)系統等(deng)作(zuo)為聽(ting)覺和視(shi)(shi)覺的(de)附屬設(she)施,施工起來(lai)整體美觀(guan)和效果都(dou)會大打(da)折扣(kou)。
五、端口
液晶拼接(jie)屏多采用產業端口例(li)如(ru)RGBBNC的(de)色差(cha)帶自鎖機構的(de)接(jie)口和專業的(de)DVI-D視(shi)頻接(jie)口;
反之,液(ye)晶電視(shi)則沒有BNC自(zi)鎖(suo)色差輸進接口和DVI-D接口;
六、控制接口
液晶拼接屏(ping)可(ke)采用S232串(chuan)口控(kong)制(zhi),開放的控(kong)制(zhi)口令多(duo)達200多(duo)條,適(shi)應各種(zhong)產業環境。方便多(duo)拼接屏(ping)使用時,不用通過(guo)遠(yuan)控(kong)器就可(ke)以控(kong)制(zhi)所有顯示設備,并能夠輔助,定時開機,延時開機、機器自檢等(deng)各種(zhong)產業要求(qiu)。
反之,液晶電視也可采用(yong)S232串口控制(zhi)。但只能實(shi)現遠控器所具備的控制(zhi)指令。并不能實(shi)現產業控制(zhi)。
七、無風扇架構
液晶拼接(jie)屏(ping)在設(she)計上采用無機(ji)械排(pai)風扇來(lai)保持空氣流通和散熱,從而(er)避(bi)免由于機(ji)械排(pai)風扇導致(zhi)的灰塵和風扇噪音題目,當內部溫(wen)度由于不明原因而(er)升高時(shi),液晶拼接(jie)屏(ping)自動控制背光系(xi)統將溫(wen)度保持在比較高工作溫(wen)度之下(xia)。
反之,液晶電視由于應用的環境所致,對此無嚴(yan)格要(yao)求(qiu)。
八.亮度
普通的(de)液(ye)晶電視亮度只有200cd/m2,而拼接拼可以達到450cd/m2或者(zhe)700cd/m2
