一、整機穩定性(包括使用時間、抗干擾等)
液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)在(zai)(zai)(zai)構成數(shu)字告示系統時(shi)(shi),通常需要(yao)(yao)天(tian)(tian)天(tian)(tian)24小(xiao)時(shi)(shi),每年(nian)365天(tian)(tian)連(lian)續無(wu)中(zhong)斷的(de)(de)(de)通電(dian)(dian)(dian)(dian)(dian)(dian)使(shi)用(yong)(yong)(而(er)電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)通常天(tian)(tian)天(tian)(tian)僅工(gong)作幾小(xiao)時(shi)(shi)),并(bing)且某(mou)些拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)應用(yong)(yong)環(huan)境(jing)可能(neng)較為惡劣,這就(jiu)要(yao)(yao)求液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)可靠性(xing)和(he)穩(wen)定性(xing)更高(gao)。與電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)相比而(er)言,在(zai)(zai)(zai)設計(ji)上(shang),液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)、功耗、溫(wen)度(du)及抗(kang)電(dian)(dian)(dian)(dian)(dian)(dian)干擾、電(dian)(dian)(dian)(dian)(dian)(dian)沖擊的(de)(de)(de)能(neng)力和(he)裕度(du)以及均(jun)勻無(wu)故障使(shi)用(yong)(yong)時(shi)(shi)間(jian)均(jun)要(yao)(yao)遠大于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji),同(tong)時(shi)(shi)液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)還必須使(shi)用(yong)(yong)全(quan)屏(ping)(ping)(ping)(ping)蔽(bi)金屬外殼確保電(dian)(dian)(dian)(dian)(dian)(dian)磁兼容(rong)和(he)干擾性(xing)能(neng);在(zai)(zai)(zai)元(yuan)(yuan)器(qi)件(jian)的(de)(de)(de)選型上(shang),液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)使(shi)用(yong)(yong)的(de)(de)(de)元(yuan)(yuan)器(qi)件(jian)的(de)(de)(de)耐壓、電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)、溫(wen)度(du)、濕度(du)等(deng)各(ge)方面特性(xing)都要(yao)(yao)高(gao)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)使(shi)用(yong)(yong)的(de)(de)(de)元(yuan)(yuan)器(qi)件(jian);而(er)在(zai)(zai)(zai)安裝、調試(shi)尤其(qi)是元(yuan)(yuan)器(qi)件(jian)和(he)整機(ji)(ji)(ji)老(lao)化(hua)的(de)(de)(de)工(gong)藝要(yao)(yao)求上(shang),液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)要(yao)(yao)求也更高(gao),電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)制造時(shi)(shi)整機(ji)(ji)(ji)老(lao)化(hua)通常是在(zai)(zai)(zai)流(liu)水(shui)線上(shang)常溫(wen)通電(dian)(dian)(dian)(dian)(dian)(dian)8小(xiao)時(shi)(shi)左右,而(er)液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)的(de)(de)(de)整機(ji)(ji)(ji)老(lao)化(hua)則需要(yao)(yao)在(zai)(zai)(zai)高(gao)溫(wen)、高(gao)濕密閉環(huan)境(jing)的(de)(de)(de)老(lao)化(hua)流(liu)水(shui)線上(shang)通電(dian)(dian)(dian)(dian)(dian)(dian)老(lao)化(hua)24小(xiao)時(shi)(shi)以上(shang),以確保整機(ji)(ji)(ji)的(de)(de)(de)穩(wen)定性(xing)。普通的(de)(de)(de)液(ye)(ye)(ye)晶(jing)(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)視使(shi)用(yong)(yong)的(de)(de)(de)LCD液(ye)(ye)(ye)晶(jing)(jing)(jing)屏(ping)(ping)(ping)(ping)其(qi)背光源(yuan)的(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(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)背光源(yuan)的(de)(de)(de)使(shi)用(yong)(yong)壽命(ming)均(jun)可達6-7萬小(xiao)時(shi)(shi)以上(shang)。液(ye)(ye)(ye)晶(jing)(jing)(jing)拼(pin)(pin)(pin)接(jie)(jie)(jie)屏(ping)(ping)(ping)(ping)廠家
二、圖像清楚度
液晶(jing)拼(pin)(pin)接(jie)顯(xian)(xian)示用具有(you)直觀(guan)反(fan)映圖像質量的功(gong)能(neng),加之(zhi)全1920*1080分(fen)辨(bian)率對于(yu)數字告示領域的顯(xian)(xian)示設備的選用,液晶(jing)拼(pin)(pin)接(jie)屏是優(you)先選擇的拼(pin)(pin)接(jie)屏,專業拼(pin)(pin)接(jie)屏分(fen)辨(bian)率是根據(ju)顯(xian)(xian)示輸出自動調整分(fen)辨(bian)率(不管橫豎都可(ke)(ke)以支(zhi)持);其(qi)高可(ke)(ke)靠性和高清(qing)楚(chu)顯(xian)(xian)示能(neng)力(li)將(jiang)保(bao)證您可(ke)(ke)以將(jiang)記錄(lu)編輯好的高清(qing)楚(chu)影(ying)音,視頻信號完整的顯(xian)(xian)示在(zai)觀(guan)看者眼前。
反之,液晶電視(shi)(shi)只(zhi)支(zhi)持說明(ming)書(shu)中規(gui)定的幾種(zhong)(zhong)電視(shi)(shi)常用(yong)分辨(bian)(bian)率(lv)。由于民(min)用(yong)電視(shi)(shi)信(xin)號(hao)的分辨(bian)(bian)率(lv)只(zhi)有幾種(zhong)(zhong),電視(shi)(shi)LCD只(zhi)要根據民(min)用(yong)用(yong)戶(hu)使用(yong)的常用(yong)幾個(ge)分辨(bian)(bian)率(lv)進(jin)行效果處理,特殊分辨(bian)(bian)率(lv)會導致(zhi)花屏。
三、色彩還原度
假如(ru)說清(qing)楚度(du)主(zhu)要(yao)是(shi)由(you)(you)視頻通道的(de)(de)(de)(de)(de)幅頻特性(xing)決(jue)定(ding)的(de)(de)(de)(de)(de)話,還原(yuan)度(du)則主(zhu)要(yao)由(you)(you)液晶(jing)拼(pin)(pin)接(jie)(jie)屏中有紅(R)、綠(G)、藍(lan)(B)三基色(se)(se)的(de)(de)(de)(de)(de)色(se)(se)度(du)信(xin)號和(he)亮度(du)信(xin)號的(de)(de)(de)(de)(de)相位所(suo)(suo)決(jue)定(ding)。由(you)(you)于(yu)液晶(jing)拼(pin)(pin)接(jie)(jie)屏所(suo)(suo)觀察(cha)的(de)(de)(de)(de)(de)通常為(wei)靜(jing)態圖像,因而對拼(pin)(pin)接(jie)(jie)屏色(se)(se)彩還原(yuan)度(du)的(de)(de)(de)(de)(de)要(yao)求比電視機更高(gao),故專業拼(pin)(pin)接(jie)(jie)屏的(de)(de)(de)(de)(de)視放通道在亮度(du)、色(se)(se)度(du)處(chu)理(li)和(he)R、G、B處(chu)理(li)上應具備的(de)(de)(de)(de)(de)補償(chang)電路和(he)延遲電路,以(yi)確保亮/色(se)(se)信(xin)號和(he)R、G、B信(xin)號的(de)(de)(de)(de)(de)相位同步(bu)。
反之,液晶電視由于使用(yong)環境要求(qiu)所至,圖象是經過潤色處理后進行顯示(shi)。不能完全(quan)真實反映實際效果。
四、機器材料的使用
由(you)于使用環境的要求,液晶電視(shi)機器外殼材質(zhi)部分(fen)采用金屬質(zhi)地。且內部板線都(dou)是產業(ye)化設計,不輕易老化;節能(neng)環保理(li)念的體(ti)現:低能(neng)耗設計;環保材料使用。規整的外觀,便于拼接,組合安裝等產業(ye)需要。
反之,液晶電視(shi)整(zheng)機外(wai)殼全(quan)部(bu)為非(fei)金屬材質(zhi)設(she)計。內部(bu)板(ban)線是采用(yong)民用(yong)設(she)計,長(chang)時(shi)間開機輕易造成機件老化。另(ling)外(wai)民用(yong)電視(shi)外(wai)觀多(duo)是非(fei)規則(ze)外(wai)觀,附帶數字(zi)標牌拼(pin)接屏系統、外(wai)觀圓弧系統等作為聽覺(jue)和視(shi)覺(jue)的附屬設(she)施(shi),施(shi)工起(qi)來整(zheng)體(ti)美(mei)觀和效果(guo)都會大(da)打折扣(kou)。
五、端口
液晶拼接屏多采用(yong)產(chan)業端口(kou)(kou)(kou)例如RGBBNC的色差帶自(zi)鎖(suo)機構的接口(kou)(kou)(kou)和專業的DVI-D視頻接口(kou)(kou)(kou);
反之,液晶電(dian)視則沒有BNC自鎖(suo)色(se)差(cha)輸進接口和DVI-D接口;
六、控制接口
液(ye)晶(jing)拼接(jie)(jie)屏(ping)(ping)可采用(yong)S232串口控制(zhi)(zhi),開(kai)(kai)放的控制(zhi)(zhi)口令多達200多條(tiao),適應各種(zhong)(zhong)產業(ye)環境(jing)。方便(bian)多拼接(jie)(jie)屏(ping)(ping)使用(yong)時,不用(yong)通過遠(yuan)控器(qi)就(jiu)可以(yi)控制(zhi)(zhi)所有(you)顯(xian)示設(she)備(bei),并能夠輔(fu)助,定(ding)時開(kai)(kai)機(ji),延時開(kai)(kai)機(ji)、機(ji)器(qi)自檢等各種(zhong)(zhong)產業(ye)要求。
反(fan)之,液晶(jing)電視也可采用(yong)S232串(chuan)口控制(zhi)。但只能實(shi)現遠控器所具備的控制(zhi)指令(ling)。并不能實(shi)現產(chan)業(ye)控制(zhi)。
七、無風扇架構
液晶(jing)拼接屏在(zai)設(she)計上采用(yong)無機械排(pai)風扇來保持空(kong)氣(qi)流通和散熱,從(cong)而(er)避免由于(yu)機械排(pai)風扇導致(zhi)的灰塵和風扇噪音題目(mu),當內部溫(wen)度由于(yu)不明原因而(er)升高時,液晶(jing)拼接屏自(zi)動控制背光系統將溫(wen)度保持在(zai)比較高工作溫(wen)度之下。
反之,液晶電視由于應用的環境所致,對此無嚴格要(yao)求(qiu)。
八.亮度
普(pu)通的液晶電視亮度(du)只有200cd/m2,而拼接拼可以達到(dao)450cd/m2或者(zhe)700cd/m2
