一、整機穩定性(包括使用時間、抗干擾等)
液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)在(zai)構(gou)成數字告示系統時(shi),通(tong)(tong)常(chang)需要(yao)(yao)天天24小(xiao)(xiao)(xiao)(xiao)時(shi),每年365天連續無中斷的(de)(de)(de)(de)(de)通(tong)(tong)電(dian)(dian)(dian)使(shi)(shi)用(yong)(yong)(yong)(而(er)電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)通(tong)(tong)常(chang)天天僅工作幾小(xiao)(xiao)(xiao)(xiao)時(shi)),并且某些(xie)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)(de)應用(yong)(yong)(yong)環(huan)境可能(neng)較為(wei)惡(e)劣,這(zhe)就要(yao)(yao)求液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)(de)可靠(kao)性(xing)和(he)(he)穩定性(xing)更高。與電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)相比而(er)言,在(zai)設計上(shang)(shang)(shang),液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)、功(gong)耗(hao)、溫(wen)(wen)(wen)度(du)及抗電(dian)(dian)(dian)干擾、電(dian)(dian)(dian)沖(chong)擊(ji)的(de)(de)(de)(de)(de)能(neng)力和(he)(he)裕(yu)度(du)以(yi)(yi)及均(jun)勻無故障使(shi)(shi)用(yong)(yong)(yong)時(shi)間均(jun)要(yao)(yao)遠(yuan)大于電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji),同(tong)時(shi)液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)還必須使(shi)(shi)用(yong)(yong)(yong)全(quan)屏(ping)(ping)蔽(bi)金(jin)屬外殼確(que)保(bao)電(dian)(dian)(dian)磁兼(jian)容(rong)和(he)(he)干擾性(xing)能(neng);在(zai)元(yuan)(yuan)器件(jian)(jian)(jian)的(de)(de)(de)(de)(de)選(xuan)型上(shang)(shang)(shang),液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)(de)元(yuan)(yuan)器件(jian)(jian)(jian)的(de)(de)(de)(de)(de)耐壓、電(dian)(dian)(dian)流(liu)、溫(wen)(wen)(wen)度(du)、濕度(du)等(deng)各方面特性(xing)都要(yao)(yao)高于電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)(de)元(yuan)(yuan)器件(jian)(jian)(jian);而(er)在(zai)安裝、調試尤其是元(yuan)(yuan)器件(jian)(jian)(jian)和(he)(he)整(zheng)機(ji)(ji)(ji)老化的(de)(de)(de)(de)(de)工藝要(yao)(yao)求上(shang)(shang)(shang),液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)(de)要(yao)(yao)求也更高,電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)制造(zao)時(shi)整(zheng)機(ji)(ji)(ji)老化通(tong)(tong)常(chang)是在(zai)流(liu)水(shui)線(xian)上(shang)(shang)(shang)常(chang)溫(wen)(wen)(wen)通(tong)(tong)電(dian)(dian)(dian)8小(xiao)(xiao)(xiao)(xiao)時(shi)左(zuo)右,而(er)液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)的(de)(de)(de)(de)(de)整(zheng)機(ji)(ji)(ji)老化則需要(yao)(yao)在(zai)高溫(wen)(wen)(wen)、高濕密(mi)閉環(huan)境的(de)(de)(de)(de)(de)老化流(liu)水(shui)線(xian)上(shang)(shang)(shang)通(tong)(tong)電(dian)(dian)(dian)老化24小(xiao)(xiao)(xiao)(xiao)時(shi)以(yi)(yi)上(shang)(shang)(shang),以(yi)(yi)確(que)保(bao)整(zheng)機(ji)(ji)(ji)的(de)(de)(de)(de)(de)穩定性(xing)。普通(tong)(tong)的(de)(de)(de)(de)(de)液(ye)(ye)晶(jing)(jing)(jing)電(dian)(dian)(dian)視(shi)(shi)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)(de)LCD液(ye)(ye)晶(jing)(jing)(jing)屏(ping)(ping)其背(bei)(bei)光(guang)源的(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命為(wei)1萬至(zhi)3萬小(xiao)(xiao)(xiao)(xiao)時(shi),而(er)液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)背(bei)(bei)光(guang)源的(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命均(jun)可達6-7萬小(xiao)(xiao)(xiao)(xiao)時(shi)以(yi)(yi)上(shang)(shang)(shang)。液(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)接(jie)(jie)(jie)(jie)(jie)屏(ping)(ping)廠(chang)家
二、圖像清楚度
液晶拼(pin)接顯(xian)(xian)示用(yong)具有(you)直觀反(fan)映圖(tu)像(xiang)質(zhi)量(liang)的功(gong)能,加之(zhi)全1920*1080分辨率對(dui)于數字告示領(ling)域的顯(xian)(xian)示設(she)備的選用(yong),液晶拼(pin)接屏是(shi)(shi)優(you)先選擇的拼(pin)接屏,專業拼(pin)接屏分辨率是(shi)(shi)根據(ju)顯(xian)(xian)示輸出自動(dong)調整分辨率(不管(guan)橫豎(shu)都可以支持);其高可靠性和高清楚顯(xian)(xian)示能力將保證您可以將記錄編輯(ji)好(hao)的高清楚影(ying)音,視頻信號完整的顯(xian)(xian)示在觀看(kan)者眼前。
反之,液晶電(dian)(dian)(dian)視只支(zhi)持(chi)說明(ming)書中規定的幾(ji)種電(dian)(dian)(dian)視常(chang)(chang)用(yong)(yong)分辨(bian)率。由于民用(yong)(yong)電(dian)(dian)(dian)視信號(hao)的分辨(bian)率只有幾(ji)種,電(dian)(dian)(dian)視LCD只要根據(ju)民用(yong)(yong)用(yong)(yong)戶使用(yong)(yong)的常(chang)(chang)用(yong)(yong)幾(ji)個分辨(bian)率進行效果(guo)處理,特殊分辨(bian)率會導致(zhi)花屏(ping)。
三、色彩還原度
假如(ru)說清楚度(du)(du)(du)主要是由視頻通(tong)道的(de)(de)(de)幅頻特性(xing)決(jue)定(ding)的(de)(de)(de)話,還原度(du)(du)(du)則(ze)主要由液(ye)(ye)晶拼接屏(ping)(ping)中有紅(R)、綠(lv)(G)、藍(B)三基色(se)的(de)(de)(de)色(se)度(du)(du)(du)信號和(he)亮(liang)度(du)(du)(du)信號的(de)(de)(de)相位所決(jue)定(ding)。由于液(ye)(ye)晶拼接屏(ping)(ping)所觀察(cha)的(de)(de)(de)通(tong)常為(wei)靜態圖像(xiang),因(yin)而對拼接屏(ping)(ping)色(se)彩(cai)還原度(du)(du)(du)的(de)(de)(de)要求比電(dian)視機更高(gao),故專業拼接屏(ping)(ping)的(de)(de)(de)視放通(tong)道在亮(liang)度(du)(du)(du)、色(se)度(du)(du)(du)處理和(he)R、G、B處理上應具備的(de)(de)(de)補償電(dian)路(lu)和(he)延(yan)遲電(dian)路(lu),以確保亮(liang)/色(se)信號和(he)R、G、B信號的(de)(de)(de)相位同步。
反(fan)之,液晶電視(shi)由于使用環境要求(qiu)所至,圖(tu)象是經(jing)過潤(run)色(se)處理后(hou)進行顯示。不能完全真實(shi)(shi)反(fan)映實(shi)(shi)際效果。
四、機器材料的使用
由于使(shi)用(yong)環境的要(yao)求,液晶(jing)電視機(ji)器外(wai)殼材質(zhi)部分(fen)采用(yong)金(jin)屬質(zhi)地(di)。且內部板線(xian)都是產業(ye)化設(she)計,不輕易老化;節能環保理念的體現:低能耗(hao)設(she)計;環保材料使(shi)用(yong)。規整(zheng)的外(wai)觀,便于拼接,組合安裝等產業(ye)需要(yao)。
反之,液(ye)晶電視(shi)(shi)整(zheng)(zheng)機外(wai)殼全(quan)部為非(fei)金屬材質設(she)計(ji)(ji)。內部板線(xian)是采用民用設(she)計(ji)(ji),長(chang)時間開機輕易造成機件老化。另外(wai)民用電視(shi)(shi)外(wai)觀(guan)多是非(fei)規(gui)則外(wai)觀(guan),附帶數(shu)字(zi)標牌拼接屏系(xi)統、外(wai)觀(guan)圓弧系(xi)統等(deng)作為聽覺(jue)和視(shi)(shi)覺(jue)的附屬設(she)施,施工起來整(zheng)(zheng)體(ti)美觀(guan)和效果都會大打(da)折扣。
五、端口
液晶(jing)拼(pin)接(jie)屏多采用產業端口例如RGBBNC的(de)(de)色差(cha)帶自鎖機構的(de)(de)接(jie)口和專業的(de)(de)DVI-D視頻接(jie)口;
反之(zhi),液晶(jing)電視則沒有BNC自鎖色(se)差輸(shu)進接口和DVI-D接口;
六、控制接口
液晶(jing)拼接屏可(ke)采用(yong)S232串口控(kong)制(zhi),開放(fang)的(de)控(kong)制(zhi)口令多達200多條,適應各種產(chan)業環境。方便多拼接屏使(shi)用(yong)時,不用(yong)通(tong)過(guo)遠控(kong)器(qi)就(jiu)可(ke)以(yi)控(kong)制(zhi)所有顯(xian)示設備,并能夠輔助,定時開機(ji),延時開機(ji)、機(ji)器(qi)自檢等(deng)各種產(chan)業要求。
反(fan)之,液(ye)晶電視也可采用S232串口(kou)控制(zhi)。但(dan)只能實(shi)現遠(yuan)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(ye)晶(jing)拼(pin)接屏在設(she)計上采(cai)用(yong)無機械(xie)排(pai)風扇來保持(chi)空氣流通和散熱,從而(er)避(bi)免(mian)由于機械(xie)排(pai)風扇導致的灰塵和風扇噪音(yin)題目,當內部(bu)溫度由于不明原因而(er)升高時(shi),液(ye)晶(jing)拼(pin)接屏自動控制背(bei)光系(xi)統將溫度保持(chi)在比較高工作(zuo)溫度之下。
反之,液(ye)晶電視由于應用的環境所致,對此(ci)無(wu)嚴格要求。
八.亮度
普(pu)通的液晶電視亮度只有200cd/m2,而拼(pin)接拼(pin)可(ke)以達到450cd/m2或(huo)者700cd/m2
