一、整機穩定性(包括使用時間、抗干擾等)
液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)在(zai)構成數字告示系統時(shi)(shi)(shi),通(tong)(tong)常需要(yao)(yao)天(tian)(tian)(tian)天(tian)(tian)(tian)24小(xiao)時(shi)(shi)(shi),每年365天(tian)(tian)(tian)連續無(wu)中斷(duan)的(de)(de)(de)通(tong)(tong)電(dian)(dian)使(shi)(shi)用(yong)(yong)(yong)(而(er)(er)電(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)通(tong)(tong)常天(tian)(tian)(tian)天(tian)(tian)(tian)僅(jin)工作幾小(xiao)時(shi)(shi)(shi)),并(bing)且某些拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)的(de)(de)(de)應用(yong)(yong)(yong)環(huan)境可能較為(wei)惡劣,這(zhe)就要(yao)(yao)求(qiu)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)的(de)(de)(de)可靠性(xing)(xing)和(he)(he)穩定性(xing)(xing)更高(gao)(gao)(gao)(gao)(gao)。與電(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)相比而(er)(er)言,在(zai)設(she)計上(shang)(shang)(shang),液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)的(de)(de)(de)電(dian)(dian)流(liu)(liu)、功耗、溫(wen)度(du)及抗電(dian)(dian)干擾、電(dian)(dian)沖擊的(de)(de)(de)能力和(he)(he)裕度(du)以(yi)及均(jun)勻(yun)無(wu)故(gu)障使(shi)(shi)用(yong)(yong)(yong)時(shi)(shi)(shi)間均(jun)要(yao)(yao)遠大于(yu)電(dian)(dian)視(shi)(shi)機(ji)(ji)(ji),同(tong)時(shi)(shi)(shi)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)還必須使(shi)(shi)用(yong)(yong)(yong)全屏(ping)(ping)(ping)(ping)(ping)蔽金(jin)屬外殼確保電(dian)(dian)磁兼容和(he)(he)干擾性(xing)(xing)能;在(zai)元(yuan)器(qi)(qi)件的(de)(de)(de)選(xuan)型上(shang)(shang)(shang),液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)元(yuan)器(qi)(qi)件的(de)(de)(de)耐壓、電(dian)(dian)流(liu)(liu)、溫(wen)度(du)、濕度(du)等各(ge)方面特性(xing)(xing)都要(yao)(yao)高(gao)(gao)(gao)(gao)(gao)于(yu)電(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)元(yuan)器(qi)(qi)件;而(er)(er)在(zai)安裝(zhuang)、調試尤其是元(yuan)器(qi)(qi)件和(he)(he)整(zheng)(zheng)(zheng)機(ji)(ji)(ji)老(lao)化(hua)的(de)(de)(de)工藝要(yao)(yao)求(qiu)上(shang)(shang)(shang),液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)的(de)(de)(de)要(yao)(yao)求(qiu)也更高(gao)(gao)(gao)(gao)(gao),電(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)制造時(shi)(shi)(shi)整(zheng)(zheng)(zheng)機(ji)(ji)(ji)老(lao)化(hua)通(tong)(tong)常是在(zai)流(liu)(liu)水(shui)(shui)線上(shang)(shang)(shang)常溫(wen)通(tong)(tong)電(dian)(dian)8小(xiao)時(shi)(shi)(shi)左(zuo)右,而(er)(er)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)的(de)(de)(de)整(zheng)(zheng)(zheng)機(ji)(ji)(ji)老(lao)化(hua)則(ze)需要(yao)(yao)在(zai)高(gao)(gao)(gao)(gao)(gao)溫(wen)、高(gao)(gao)(gao)(gao)(gao)濕密閉環(huan)境的(de)(de)(de)老(lao)化(hua)流(liu)(liu)水(shui)(shui)線上(shang)(shang)(shang)通(tong)(tong)電(dian)(dian)老(lao)化(hua)24小(xiao)時(shi)(shi)(shi)以(yi)上(shang)(shang)(shang),以(yi)確保整(zheng)(zheng)(zheng)機(ji)(ji)(ji)的(de)(de)(de)穩定性(xing)(xing)。普通(tong)(tong)的(de)(de)(de)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)電(dian)(dian)視(shi)(shi)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)LCD液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)屏(ping)(ping)(ping)(ping)(ping)其背光(guang)源的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命(ming)為(wei)1萬(wan)(wan)至3萬(wan)(wan)小(xiao)時(shi)(shi)(shi),而(er)(er)液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)背光(guang)源的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命(ming)均(jun)可達6-7萬(wan)(wan)小(xiao)時(shi)(shi)(shi)以(yi)上(shang)(shang)(shang)。液(ye)(ye)(ye)晶(jing)(jing)(jing)(jing)拼(pin)(pin)接屏(ping)(ping)(ping)(ping)(ping)廠家
二、圖像清楚度
液晶拼接顯(xian)(xian)示(shi)(shi)(shi)用具(ju)有直(zhi)觀反映圖像(xiang)質量的(de)功能(neng),加之全1920*1080分(fen)(fen)辨率對于數字告示(shi)(shi)(shi)領(ling)域的(de)顯(xian)(xian)示(shi)(shi)(shi)設備的(de)選用,液晶拼接屏(ping)是(shi)(shi)優(you)先(xian)選擇的(de)拼接屏(ping),專(zhuan)業(ye)拼接屏(ping)分(fen)(fen)辨率是(shi)(shi)根據顯(xian)(xian)示(shi)(shi)(shi)輸出自動(dong)調整分(fen)(fen)辨率(不管橫豎都(dou)可以支持);其高(gao)可靠性(xing)和高(gao)清楚顯(xian)(xian)示(shi)(shi)(shi)能(neng)力(li)將保證您可以將記(ji)錄編輯好的(de)高(gao)清楚影音,視頻信(xin)號完(wan)整的(de)顯(xian)(xian)示(shi)(shi)(shi)在觀看者眼前(qian)。
反(fan)之(zhi),液(ye)晶電視(shi)(shi)只支(zhi)持說明書中規定(ding)的(de)幾(ji)種電視(shi)(shi)常用(yong)(yong)分辨率(lv)(lv)。由于民(min)用(yong)(yong)電視(shi)(shi)信號的(de)分辨率(lv)(lv)只有(you)幾(ji)種,電視(shi)(shi)LCD只要根據民(min)用(yong)(yong)用(yong)(yong)戶使用(yong)(yong)的(de)常用(yong)(yong)幾(ji)個分辨率(lv)(lv)進行效果處理,特殊分辨率(lv)(lv)會導致花屏。
三、色彩還原度
假(jia)如(ru)說清(qing)楚度(du)(du)主(zhu)(zhu)要(yao)(yao)是由視頻通(tong)道的(de)幅頻特性決(jue)定的(de)話,還原(yuan)(yuan)度(du)(du)則主(zhu)(zhu)要(yao)(yao)由液晶(jing)拼(pin)接屏中有紅(R)、綠(G)、藍(lan)(B)三基色(se)的(de)色(se)度(du)(du)信(xin)(xin)(xin)號(hao)和(he)(he)亮(liang)度(du)(du)信(xin)(xin)(xin)號(hao)的(de)相(xiang)位所決(jue)定。由于液晶(jing)拼(pin)接屏所觀察(cha)的(de)通(tong)常為(wei)靜態圖像(xiang),因(yin)而(er)對拼(pin)接屏色(se)彩還原(yuan)(yuan)度(du)(du)的(de)要(yao)(yao)求(qiu)比電視機更高,故專業拼(pin)接屏的(de)視放通(tong)道在(zai)亮(liang)度(du)(du)、色(se)度(du)(du)處(chu)理和(he)(he)R、G、B處(chu)理上應具備的(de)補償電路和(he)(he)延(yan)遲電路,以確保亮(liang)/色(se)信(xin)(xin)(xin)號(hao)和(he)(he)R、G、B信(xin)(xin)(xin)號(hao)的(de)相(xiang)位同步。
反之,液晶電(dian)視由于(yu)使(shi)用環境要求所至,圖象是(shi)經過潤色處理后進(jin)行(xing)顯示。不能完全真實反映實際效果。
四、機器材料的使用
由于(yu)使(shi)用環境(jing)的要求(qiu),液晶電視機器外(wai)殼材(cai)質(zhi)部(bu)分采用金屬(shu)質(zhi)地。且內部(bu)板線都(dou)是產業(ye)(ye)化設計,不輕易老化;節能環保(bao)理(li)念的體現(xian):低(di)能耗(hao)設計;環保(bao)材(cai)料使(shi)用。規整的外(wai)觀,便于(yu)拼接(jie),組合安裝等產業(ye)(ye)需(xu)要。
反(fan)之(zhi),液晶電(dian)視整機外(wai)(wai)殼全(quan)部為(wei)非金屬材質設計。內部板線是(shi)采(cai)用(yong)民用(yong)設計,長(chang)時間開(kai)機輕易造成機件老化。另(ling)外(wai)(wai)民用(yong)電(dian)視外(wai)(wai)觀(guan)(guan)多是(shi)非規則外(wai)(wai)觀(guan)(guan),附帶數字標牌拼接屏系(xi)統(tong)、外(wai)(wai)觀(guan)(guan)圓弧系(xi)統(tong)等作為(wei)聽覺和視覺的(de)附屬設施,施工起(qi)來整體美觀(guan)(guan)和效果都會大打折扣。
五、端口
液晶拼接(jie)屏多采用產業(ye)端口例如RGBBNC的色差帶自鎖機構的接(jie)口和專(zhuan)業(ye)的DVI-D視頻接(jie)口;
反(fan)之,液(ye)晶電視則沒有BNC自鎖色差輸(shu)進接口和DVI-D接口;
六、控制接口
液晶拼接(jie)(jie)屏可(ke)采用S232串口控(kong)制(zhi),開(kai)放的控(kong)制(zhi)口令多達200多條,適應各種產業環境(jing)。方(fang)便多拼接(jie)(jie)屏使用時,不用通過遠控(kong)器就(jiu)可(ke)以控(kong)制(zhi)所(suo)有顯示設備,并能(neng)夠輔助,定時開(kai)機,延時開(kai)機、機器自檢等各種產業要求。
反之(zhi),液(ye)晶電視也可采用S232串口(kou)控(kong)制。但只能實現遠控(kong)器所具備的(de)控(kong)制指(zhi)令。并不能實現產業(ye)控(kong)制。
七、無風扇架構
液晶拼接屏在設計上采用無機(ji)械(xie)排風(feng)扇(shan)來保(bao)持空氣(qi)流通和散(san)熱,從而避免由(you)于機(ji)械(xie)排風(feng)扇(shan)導致(zhi)的灰(hui)塵和風(feng)扇(shan)噪音題目,當(dang)內部溫度(du)由(you)于不明原因而升高(gao)時,液晶拼接屏自動控制(zhi)背光系(xi)統將溫度(du)保(bao)持在比較高(gao)工(gong)作(zuo)溫度(du)之下。
反之,液晶電視由于(yu)應用(yong)的環境(jing)所(suo)致(zhi),對此無嚴(yan)格要求。
八.亮度
普通(tong)的液晶電視亮(liang)度(du)只有200cd/m2,而拼接拼可以(yi)達(da)到(dao)450cd/m2或者700cd/m2
