一、整機穩定性(包括使用時間、抗干擾等)
液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)在構成數字告示系統時(shi),通(tong)(tong)常(chang)(chang)需要(yao)天天24小(xiao)時(shi),每年365天連續無(wu)中斷的(de)(de)(de)通(tong)(tong)電(dian)(dian)(dian)使(shi)用(yong)(yong)(yong)(而(er)電(dian)(dian)(dian)視(shi)機(ji)通(tong)(tong)常(chang)(chang)天天僅工(gong)(gong)作幾小(xiao)時(shi)),并(bing)且某些拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)應用(yong)(yong)(yong)環境可能較為惡劣,這就(jiu)要(yao)求(qiu)液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)可靠性(xing)(xing)和(he)穩(wen)定(ding)性(xing)(xing)更高。與(yu)電(dian)(dian)(dian)視(shi)機(ji)相比而(er)言,在設計上(shang)(shang),液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)電(dian)(dian)(dian)流(liu)、功(gong)耗、溫(wen)度(du)(du)及抗電(dian)(dian)(dian)干擾、電(dian)(dian)(dian)沖擊的(de)(de)(de)能力(li)和(he)裕(yu)度(du)(du)以及均(jun)勻無(wu)故障使(shi)用(yong)(yong)(yong)時(shi)間均(jun)要(yao)遠大于電(dian)(dian)(dian)視(shi)機(ji),同時(shi)液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)還(huan)必須使(shi)用(yong)(yong)(yong)全屏(ping)(ping)蔽(bi)金(jin)屬(shu)外殼確保(bao)電(dian)(dian)(dian)磁兼容和(he)干擾性(xing)(xing)能;在元(yuan)器(qi)件(jian)的(de)(de)(de)選(xuan)型上(shang)(shang),液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)使(shi)用(yong)(yong)(yong)的(de)(de)(de)元(yuan)器(qi)件(jian)的(de)(de)(de)耐壓(ya)、電(dian)(dian)(dian)流(liu)、溫(wen)度(du)(du)、濕度(du)(du)等各方面特性(xing)(xing)都要(yao)高于電(dian)(dian)(dian)視(shi)機(ji)使(shi)用(yong)(yong)(yong)的(de)(de)(de)元(yuan)器(qi)件(jian);而(er)在安裝(zhuang)、調(diao)試尤其是(shi)元(yuan)器(qi)件(jian)和(he)整機(ji)老化(hua)(hua)的(de)(de)(de)工(gong)(gong)藝要(yao)求(qiu)上(shang)(shang),液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)要(yao)求(qiu)也(ye)更高,電(dian)(dian)(dian)視(shi)機(ji)制造時(shi)整機(ji)老化(hua)(hua)通(tong)(tong)常(chang)(chang)是(shi)在流(liu)水(shui)(shui)線(xian)上(shang)(shang)常(chang)(chang)溫(wen)通(tong)(tong)電(dian)(dian)(dian)8小(xiao)時(shi)左右(you),而(er)液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)整機(ji)老化(hua)(hua)則需要(yao)在高溫(wen)、高濕密閉環境的(de)(de)(de)老化(hua)(hua)流(liu)水(shui)(shui)線(xian)上(shang)(shang)通(tong)(tong)電(dian)(dian)(dian)老化(hua)(hua)24小(xiao)時(shi)以上(shang)(shang),以確保(bao)整機(ji)的(de)(de)(de)穩(wen)定(ding)性(xing)(xing)。普通(tong)(tong)的(de)(de)(de)液(ye)晶(jing)(jing)(jing)(jing)電(dian)(dian)(dian)視(shi)使(shi)用(yong)(yong)(yong)的(de)(de)(de)LCD液(ye)晶(jing)(jing)(jing)(jing)屏(ping)(ping)其背光源(yuan)(yuan)的(de)(de)(de)使(shi)用(yong)(yong)(yong)壽(shou)命為1萬(wan)至(zhi)3萬(wan)小(xiao)時(shi),而(er)液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)背光源(yuan)(yuan)的(de)(de)(de)使(shi)用(yong)(yong)(yong)壽(shou)命均(jun)可達6-7萬(wan)小(xiao)時(shi)以上(shang)(shang)。液(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)廠家
二、圖像清楚度
液(ye)晶(jing)拼(pin)(pin)接顯(xian)(xian)示(shi)(shi)用(yong)具有直觀反映圖像質量的(de)(de)功(gong)能,加之全1920*1080分辨率對于(yu)數字告(gao)示(shi)(shi)領域的(de)(de)顯(xian)(xian)示(shi)(shi)設備(bei)的(de)(de)選用(yong),液(ye)晶(jing)拼(pin)(pin)接屏是優先選擇(ze)的(de)(de)拼(pin)(pin)接屏,專業(ye)拼(pin)(pin)接屏分辨率是根據顯(xian)(xian)示(shi)(shi)輸出自動調(diao)整分辨率(不管(guan)橫(heng)豎(shu)都可(ke)(ke)以支(zhi)持);其(qi)高(gao)可(ke)(ke)靠性(xing)和高(gao)清楚顯(xian)(xian)示(shi)(shi)能力將(jiang)保證您可(ke)(ke)以將(jiang)記錄編(bian)輯好的(de)(de)高(gao)清楚影音,視頻信號(hao)完整的(de)(de)顯(xian)(xian)示(shi)(shi)在觀看者眼前。
反之,液(ye)晶電(dian)視(shi)只(zhi)(zhi)支持(chi)說明書中(zhong)規定(ding)的幾(ji)種電(dian)視(shi)常用(yong)分(fen)(fen)辨(bian)(bian)率(lv)。由(you)于(yu)民用(yong)電(dian)視(shi)信號的分(fen)(fen)辨(bian)(bian)率(lv)只(zhi)(zhi)有(you)幾(ji)種,電(dian)視(shi)LCD只(zhi)(zhi)要根據民用(yong)用(yong)戶使用(yong)的常用(yong)幾(ji)個分(fen)(fen)辨(bian)(bian)率(lv)進行效果處理,特(te)殊(shu)分(fen)(fen)辨(bian)(bian)率(lv)會(hui)導致花屏。
三、色彩還原度
假如說清楚度(du)(du)主(zhu)要(yao)(yao)是由(you)視頻通(tong)道的(de)(de)(de)幅頻特性決(jue)(jue)定的(de)(de)(de)話,還(huan)原度(du)(du)則(ze)主(zhu)要(yao)(yao)由(you)液晶(jing)拼接(jie)(jie)屏中有紅(R)、綠(lv)(G)、藍(B)三(san)基色(se)的(de)(de)(de)色(se)度(du)(du)信號(hao)和(he)亮(liang)度(du)(du)信號(hao)的(de)(de)(de)相位所(suo)決(jue)(jue)定。由(you)于液晶(jing)拼接(jie)(jie)屏所(suo)觀察的(de)(de)(de)通(tong)常(chang)為靜態圖像,因而對拼接(jie)(jie)屏色(se)彩還(huan)原度(du)(du)的(de)(de)(de)要(yao)(yao)求比電(dian)視機更高,故專業拼接(jie)(jie)屏的(de)(de)(de)視放(fang)通(tong)道在亮(liang)度(du)(du)、色(se)度(du)(du)處(chu)理和(he)R、G、B處(chu)理上應具備的(de)(de)(de)補償電(dian)路和(he)延遲(chi)電(dian)路,以確保亮(liang)/色(se)信號(hao)和(he)R、G、B信號(hao)的(de)(de)(de)相位同步(bu)。
反(fan)之,液晶電視由于(yu)使用環(huan)境要(yao)求所至(zhi),圖象是經(jing)過潤色處理后進行顯示。不能完全真實反(fan)映實際效果。
四、機器材料的使用
由于使用(yong)環(huan)境的(de)(de)要(yao)(yao)求(qiu),液晶電視(shi)機(ji)器外(wai)殼(ke)材(cai)質部分(fen)采用(yong)金屬質地(di)。且內部板線都是產(chan)業化設(she)計,不輕易老化;節能環(huan)保(bao)理念(nian)的(de)(de)體現(xian):低能耗設(she)計;環(huan)保(bao)材(cai)料使用(yong)。規整的(de)(de)外(wai)觀,便于拼接,組合安裝等產(chan)業需要(yao)(yao)。
反(fan)之,液晶電視(shi)整機(ji)外(wai)殼全部(bu)為非(fei)金屬(shu)(shu)材質設(she)(she)計(ji)。內部(bu)板線是(shi)采用(yong)民用(yong)設(she)(she)計(ji),長(chang)時(shi)間(jian)開機(ji)輕易造成機(ji)件老化。另(ling)外(wai)民用(yong)電視(shi)外(wai)觀多是(shi)非(fei)規則外(wai)觀,附(fu)帶數(shu)字(zi)標(biao)牌(pai)拼接屏系(xi)統(tong)、外(wai)觀圓(yuan)弧系(xi)統(tong)等作為聽覺和視(shi)覺的附(fu)屬(shu)(shu)設(she)(she)施,施工起(qi)來(lai)整體美觀和效果都(dou)會大打(da)折扣。
五、端口
液晶拼接(jie)屏多采用產業(ye)端口(kou)例如RGBBNC的色(se)差帶自鎖機構的接(jie)口(kou)和專業(ye)的DVI-D視頻(pin)接(jie)口(kou);
反之,液晶電視則(ze)沒(mei)有BNC自鎖色差輸進接口和DVI-D接口;
六、控制接口
液晶拼接屏可采用(yong)S232串口控制(zhi),開(kai)(kai)放(fang)的控制(zhi)口令多達200多條(tiao),適應各種產業環(huan)境。方便多拼接屏使(shi)用(yong)時,不用(yong)通過遠控器就(jiu)可以控制(zhi)所有(you)顯(xian)示設備,并能夠輔助,定時開(kai)(kai)機,延時開(kai)(kai)機、機器自檢(jian)等各種產業要求(qiu)。
反之,液(ye)晶電視也(ye)可采用(yong)S232串口控(kong)制(zhi)。但只(zhi)能實現(xian)遠控(kong)器所具備的控(kong)制(zhi)指令。并不能實現(xian)產業控(kong)制(zhi)。
七、無風扇架構
液晶拼接屏(ping)在設計(ji)上采用無機械(xie)排風扇(shan)來保(bao)持(chi)空氣流通和(he)散(san)熱(re),從而避免由(you)于機械(xie)排風扇(shan)導致(zhi)的灰塵和(he)風扇(shan)噪音題目,當內部溫(wen)度由(you)于不明原因而升高時,液晶拼接屏(ping)自動控(kong)制背光系統將(jiang)溫(wen)度保(bao)持(chi)在比較(jiao)高工作溫(wen)度之(zhi)下。
反之,液晶電(dian)視由(you)于應(ying)用的環境所致,對(dui)此無嚴格要求(qiu)。
八.亮度
普通(tong)的液晶(jing)電視亮度只有200cd/m2,而拼接拼可以達到450cd/m2或者700cd/m2
