 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
