九口科技提出關于tcl監視器選購與工程應用的幾個問題
目前，tcl監視器<>憑借其本身的優勢，逐漸成為主流產品，大有取代CRT監視器的趨勢。隨著tcl監視器生產廠家也越來越多，產品的質量也就呈現出參差不齊的現象。而工程商對tcl監視器<>的認識還不是很深入，在購買tcl監視器<>時沒有正確的評判。因此，本刊編輯特地搜集了tcl監視器<>與工程相關的問題，以供讀者朋友們分享。
液晶電視機可以當作tcl監視器<>用嗎？
tcl監視器<>在(zai)(zai)功能(neng)上(shang)比電(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機(ji)(ji)簡單，但在(zai)(zai)性能(neng)上(shang)，卻比電(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機(ji)(ji)要求高(gao)。LCD監(jian)視(shi)(shi)(shi)(shi)器(qi)(qi)的(de)(de)(de)(de)核(he)心部件是(shi)專(zhuan)業的(de)(de)(de)(de)圖像處理方(fang)案和液(ye)晶面板(ban)。與液(ye)晶電(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機(ji)(ji)不(bu)同的(de)(de)(de)(de)是(shi)，它采用的(de)(de)(de)(de)圖像處理方(fang)案比液(ye)晶電(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機(ji)(ji)的(de)(de)(de)(de)要高(gao)。如果(guo)用液(ye)晶電(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機(ji)(ji)當監(jian)視(shi)(shi)(shi)(shi)器(qi)(qi)用，在(zai)(zai)信(xin)號(hao)比較好的(de)(de)(de)(de)情況(kuang)下，其(qi)效(xiao)果(guo)可(ke)能(neng)和LCD監(jian)視(shi)(shi)(shi)(shi)器(qi)(qi)的(de)(de)(de)(de)效(xiao)果(guo)差(cha)異不(bu)大，但是(shi)當信(xin)號(hao)不(bu)好的(de)(de)(de)(de)時候，效(xiao)果(guo)就(jiu)要明(ming)顯差(cha)很多。
