一、整機穩定性(包括使用時間、抗干擾等)
液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)在構成數(shu)字告示系統時(shi)(shi),通(tong)(tong)(tong)常需要天天24小(xiao)時(shi)(shi),每年365天連續無中斷的(de)(de)(de)(de)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)使(shi)(shi)用(yong)(yong)(yong)(而電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)通(tong)(tong)(tong)常天天僅工作幾小(xiao)時(shi)(shi)),并(bing)且某些拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)(de)應用(yong)(yong)(yong)環境可能較為惡劣,這就要求(qiu)液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)(de)可靠性和穩定(ding)性更高。與電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)相比而言,在設計(ji)上(shang)(shang),液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流、功耗、溫(wen)度及(ji)抗電(dian)(dian)(dian)(dian)干(gan)擾、電(dian)(dian)(dian)(dian)沖(chong)擊的(de)(de)(de)(de)能力和裕(yu)度以(yi)(yi)(yi)及(ji)均勻無故障使(shi)(shi)用(yong)(yong)(yong)時(shi)(shi)間均要遠大于(yu)(yu)電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji),同時(shi)(shi)液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)還必須使(shi)(shi)用(yong)(yong)(yong)全屏(ping)(ping)(ping)(ping)蔽金屬外殼(ke)確保(bao)電(dian)(dian)(dian)(dian)磁兼容和干(gan)擾性能;在元(yuan)器(qi)(qi)件(jian)的(de)(de)(de)(de)選(xuan)型上(shang)(shang),液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)元(yuan)器(qi)(qi)件(jian)的(de)(de)(de)(de)耐壓、電(dian)(dian)(dian)(dian)流、溫(wen)度、濕(shi)度等各方面特性都要高于(yu)(yu)電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)元(yuan)器(qi)(qi)件(jian);而在安裝、調試尤(you)其是(shi)元(yuan)器(qi)(qi)件(jian)和整(zheng)機(ji)(ji)老(lao)化(hua)(hua)的(de)(de)(de)(de)工藝要求(qiu)上(shang)(shang),液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)(de)要求(qiu)也更高,電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)制造時(shi)(shi)整(zheng)機(ji)(ji)老(lao)化(hua)(hua)通(tong)(tong)(tong)常是(shi)在流水線上(shang)(shang)常溫(wen)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)8小(xiao)時(shi)(shi)左右,而液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)(de)整(zheng)機(ji)(ji)老(lao)化(hua)(hua)則需要在高溫(wen)、高濕(shi)密閉環境的(de)(de)(de)(de)老(lao)化(hua)(hua)流水線上(shang)(shang)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)老(lao)化(hua)(hua)24小(xiao)時(shi)(shi)以(yi)(yi)(yi)上(shang)(shang),以(yi)(yi)(yi)確保(bao)整(zheng)機(ji)(ji)的(de)(de)(de)(de)穩定(ding)性。普(pu)通(tong)(tong)(tong)的(de)(de)(de)(de)液(ye)(ye)晶(jing)(jing)(jing)(jing)電(dian)(dian)(dian)(dian)視(shi)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)LCD液(ye)(ye)晶(jing)(jing)(jing)(jing)屏(ping)(ping)(ping)(ping)其背光源的(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命(ming)為1萬(wan)至3萬(wan)小(xiao)時(shi)(shi),而液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)背光源的(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命(ming)均可達6-7萬(wan)小(xiao)時(shi)(shi)以(yi)(yi)(yi)上(shang)(shang)。液(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)接(jie)(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)廠家
二、圖像清楚度
液(ye)晶拼(pin)(pin)接顯示用具有直觀反映(ying)圖像(xiang)質量(liang)的功能,加之全1920*1080分(fen)辨率對于數字告示領域(yu)的顯示設(she)備的選用,液(ye)晶拼(pin)(pin)接屏是優先(xian)選擇的拼(pin)(pin)接屏,專業拼(pin)(pin)接屏分(fen)辨率是根據顯示輸出自動調整分(fen)辨率(不(bu)管橫豎都可(ke)以支持(chi));其高可(ke)靠性和高清楚顯示能力將保證(zheng)您可(ke)以將記錄編(bian)輯好的高清楚影(ying)音,視頻信號(hao)完整的顯示在(zai)觀看(kan)者眼前。
反之,液晶(jing)電視只(zhi)(zhi)支(zhi)持說明書中規定的幾種電視常(chang)(chang)用(yong)(yong)分辨率。由(you)于民用(yong)(yong)電視信號的分辨率只(zhi)(zhi)有幾種,電視LCD只(zhi)(zhi)要根據民用(yong)(yong)用(yong)(yong)戶(hu)使用(yong)(yong)的常(chang)(chang)用(yong)(yong)幾個分辨率進行效果處理,特殊(shu)分辨率會(hui)導致(zhi)花屏。
三、色彩還原度
假如說清楚度主要是由視(shi)頻通(tong)(tong)道的幅(fu)頻特性決(jue)定(ding)的話,還(huan)原度則主要由液(ye)晶拼(pin)(pin)接(jie)屏中有(you)紅(R)、綠(lv)(G)、藍(B)三基色(se)的色(se)度信號(hao)和亮(liang)(liang)度信號(hao)的相(xiang)位(wei)所決(jue)定(ding)。由于液(ye)晶拼(pin)(pin)接(jie)屏所觀察的通(tong)(tong)常為靜(jing)態圖像,因而對(dui)拼(pin)(pin)接(jie)屏色(se)彩還(huan)原度的要求比電視(shi)機(ji)更高,故專業拼(pin)(pin)接(jie)屏的視(shi)放通(tong)(tong)道在亮(liang)(liang)度、色(se)度處理(li)(li)和R、G、B處理(li)(li)上應(ying)具備(bei)的補(bu)償電路和延遲電路,以確(que)保亮(liang)(liang)/色(se)信號(hao)和R、G、B信號(hao)的相(xiang)位(wei)同步。
反(fan)之,液晶電視(shi)由于使用環境要求(qiu)所至(zhi),圖象是經過(guo)潤色處理后進(jin)行(xing)顯示。不能完全真(zhen)實反(fan)映實際效果。
四、機器材料的使用
由于使用環境的要求,液晶電視機器外(wai)殼材質部分(fen)采用金(jin)屬質地。且內部板線都(dou)是產(chan)業(ye)(ye)化設計,不輕易老化;節(jie)能(neng)環保理念的體現:低能(neng)耗設計;環保材料使用。規整的外(wai)觀,便(bian)于拼接,組(zu)合安裝等產(chan)業(ye)(ye)需要。
反之,液晶(jing)電視整機外殼全部(bu)為非金屬材質設(she)計。內部(bu)板線(xian)是采(cai)用民(min)用設(she)計,長時間開機輕易造成機件(jian)老化(hua)。另外民(min)用電視外觀(guan)多是非規則外觀(guan),附帶數字(zi)標牌拼接(jie)屏系統(tong)、外觀(guan)圓(yuan)弧系統(tong)等作為聽覺(jue)和視覺(jue)的附屬設(she)施,施工(gong)起來(lai)整體美觀(guan)和效(xiao)果(guo)都會大打(da)折扣。
五、端口
液(ye)晶(jing)拼接(jie)屏多采用產業(ye)端口例如RGBBNC的(de)色差(cha)帶自(zi)鎖機構的(de)接(jie)口和(he)專業(ye)的(de)DVI-D視(shi)頻接(jie)口;
反之(zhi),液晶電視則沒有BNC自鎖色差輸進接口(kou)和DVI-D接口(kou);
六、控制接口
液晶拼接屏可采用S232串口(kou)控(kong)制(zhi),開放的控(kong)制(zhi)口(kou)令多(duo)達200多(duo)條,適應各種產(chan)業(ye)環境。方便多(duo)拼接屏使用時(shi),不用通過(guo)遠控(kong)器就可以控(kong)制(zhi)所有顯示(shi)設備,并能夠輔(fu)助,定時(shi)開機(ji)(ji),延時(shi)開機(ji)(ji)、機(ji)(ji)器自(zi)檢(jian)等各種產(chan)業(ye)要(yao)求。
反(fan)之,液晶(jing)電視也可采(cai)用(yong)S232串口控(kong)制。但只(zhi)能實(shi)(shi)現遠控(kong)器所具備的(de)控(kong)制指令。并不能實(shi)(shi)現產業(ye)控(kong)制。
七、無風扇架構
液(ye)晶(jing)拼接屏在(zai)設計上采(cai)用無機(ji)(ji)械排風(feng)(feng)扇(shan)來保持空氣流通和散(san)熱,從而避(bi)免由于機(ji)(ji)械排風(feng)(feng)扇(shan)導致的灰塵和風(feng)(feng)扇(shan)噪(zao)音題目(mu),當內部(bu)溫(wen)度(du)由于不明原因而升高時,液(ye)晶(jing)拼接屏自(zi)動控制背光系統將溫(wen)度(du)保持在(zai)比較高工(gong)作溫(wen)度(du)之下。
反之,液(ye)晶(jing)電視由于應用的環境(jing)所致,對此無嚴格要求。
八.亮度
普通的液晶(jing)電(dian)視亮度(du)只有200cd/m2,而拼接拼可以達到(dao)450cd/m2或者700cd/m2
