液晶面板(ban)(ban)生(sheng)產(chan)線世(shi)代(dai)的(de)劃(hua)分是根據(ju)玻璃基板(ban)(ban)的(de)大(da)小來劃(hua)分的(de)，世(shi)代(dai)的(de)不同(tong)其(qi)主力(li)切割的(de)產(chan)品尺(chi)寸不同(tong)，產(chan)品技術(shu)沒(mei)有區別，生(sheng)產(chan)工藝技術(shu)略有不同(tong)。

        所謂(wei)產品技(ji)(ji)術相(xiang)同(tong)：如(ru)32寸的電視，分辨不(bu)出是由6代線(xian)(xian)還是7代線(xian)(xian)還是其他代線(xian)(xian)生(sheng)產出來的，質量(liang)性能一樣(yang)；所謂(wei)生(sheng)產工(gong)藝技(ji)(ji)術不(bu)同(tong)：如(ru)4代線(xian)(xian)玻(bo)(bo)璃(li)基板在(zai)生(sheng)產流(liu)程中(zhong)是水平(ping)放置，8代線(xian)(xian)以上由于玻(bo)(bo)璃(li)基板巨大(da)，在(zai)生(sheng)產過程中(zhong)要垂直或傾斜式放置。

        我們經常在媒體上(shang)可以看到某某液晶面(mian)板廠幾代線(xian)投產之(zhi)類的新(xin)聞，在講TFT-LCD面(mian)板生(sheng)產線(xian)的進步之(zhi)前(qian)，我們有必要對各代面(mian)板生(sheng)產線(xian)進行一個了解(jie)。

        TFT-LCD基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)的(de)(de)切(qie)割(ge)片(pian)(pian)(pian)數有一個(ge)最佳經濟值(zhi)，達到這個(ge)值(zhi)以(yi)(yi)上(shang)意味著較高(gao)的(de)(de)生產(chan)(chan)效(xiao)率，業界公認的(de)(de)經濟切(qie)割(ge)片(pian)(pian)(pian)數是(shi)(shi)(shi)6。按照(zhao)玻(bo)璃基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)尺(chi)寸(cun)的(de)(de)大小劃分生產(chan)(chan)線(xian)屬(shu)于哪(na)一代(dai)(dai)(dai)，5代(dai)(dai)(dai)線(xian)最高(gao)階段的(de)(de)基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)尺(chi)寸(cun)是(shi)(shi)(shi)1200X1300mm，最多能切(qie)割(ge)6片(pian)(pian)(pian)27英寸(cun)寬屏LCD-TV用基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)，所以(yi)(yi)5代(dai)(dai)(dai)線(xian)的(de)(de)上(shang)限是(shi)(shi)(shi)27英寸(cun)寬屏電視機。6代(dai)(dai)(dai)線(xian)基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)尺(chi)寸(cun)為1500X1800mm，切(qie)割(ge)32英寸(cun)基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)可(ke)以(yi)(yi)切(qie)割(ge)8片(pian)(pian)(pian)，37英寸(cun)可(ke)以(yi)(yi)切(qie)割(ge)6片(pian)(pian)(pian)，所以(yi)(yi)6代(dai)(dai)(dai)線(xian)的(de)(de)上(shang)限是(shi)(shi)(shi)37英寸(cun)。7代(dai)(dai)(dai)線(xian)的(de)(de)基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)尺(chi)寸(cun)是(shi)(shi)(shi)1870X2200mm，切(qie)割(ge)42英寸(cun)基(ji)(ji)(ji)(ji)板(ban)(ban)(ban)可(ke)以(yi)(yi)切(qie)割(ge)8片(pian)(pian)(pian)，46英寸(cun)可(ke)以(yi)(yi)切(qie)割(ge)6片(pian)(pian)(pian)。所以(yi)(yi)7代(dai)(dai)(dai)線(xian)的(de)(de)上(shang)限是(shi)(shi)(shi)46英寸(cun)。

        生(sheng)(sheng)產(chan)(chan)TFT-LCD面板(ban)(ban)的(de)(de)(de)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)(xian)可(ke)以分(fen)為(wei)三代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)、四代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)、五代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)以及六(liu)代(dai)(dai)(dai)(dai)(dai)和(he)七(qi)代(dai)(dai)(dai)(dai)(dai)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)(xian)。第三代(dai)(dai)(dai)(dai)(dai)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)(xian)TFT玻(bo)璃基(ji)(ji)板(ban)(ban)尺寸(cun)(cun)(cun)為(wei)550mm×650mm，可(ke)切(qie)割成4片(pian)15寸(cun)(cun)(cun)液(ye)(ye)晶(jing)(jing)(jing)監視(shi)(shi)器面板(ban)(ban)，第四代(dai)(dai)(dai)(dai)(dai)的(de)(de)(de)玻(bo)璃基(ji)(ji)板(ban)(ban)尺寸(cun)(cun)(cun)為(wei)680mm×880mm，可(ke)切(qie)割成6片(pian)15寸(cun)(cun)(cun)面板(ban)(ban)，而(er)五代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)生(sheng)(sheng)產(chan)(chan)基(ji)(ji)板(ban)(ban)尺寸(cun)(cun)(cun)為(wei)1100×1250mm，可(ke)以切(qie)割12片(pian)17寸(cun)(cun)(cun)面板(ban)(ban)或6片(pian)24英寸(cun)(cun)(cun)面板(ban)(ban)。 建設(she)五代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)還是六(liu)代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)，主(zhu)要看企業的(de)(de)(de)產(chan)(chan)品定(ding)位。五代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)的(de)(de)(de)經濟(ji)(ji)切(qie)割尺寸(cun)(cun)(cun)一(yi)般認為(wei)定(ding)位為(wei)17～26英寸(cun)(cun)(cun)的(de)(de)(de)液(ye)(ye)晶(jing)(jing)(jing)顯(xian)示器和(he)液(ye)(ye)晶(jing)(jing)(jing)電視(shi)(shi)比較(jiao)合理(li)，六(liu)代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)產(chan)(chan)品定(ding)位為(wei)26～37英寸(cun)(cun)(cun)液(ye)(ye)晶(jing)(jing)(jing)電視(shi)(shi)，七(qi)代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)適于生(sheng)(sheng)產(chan)(chan)40英寸(cun)(cun)(cun)以上(shang)(shang)液(ye)(ye)晶(jing)(jing)(jing)電視(shi)(shi)。目前(qian)市場上(shang)(shang)銷量最好的(de)(de)(de)液(ye)(ye)晶(jing)(jing)(jing)電視(shi)(shi)是17～27英寸(cun)(cun)(cun)，在(zai)個性化的(de)(de)(de)時代(dai)(dai)(dai)(dai)(dai)，中(zhong)小尺寸(cun)(cun)(cun)電視(shi)(shi)將有可(ke)觀的(de)(de)(de)市場。六(liu)代(dai)(dai)(dai)(dai)(dai)以上(shang)(shang)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)(xian)如果切(qie)割小尺寸(cun)(cun)(cun)，不僅不經濟(ji)(ji)，良品率也不會高，在(zai)競(jing)爭中(zhong)會處于劣勢。事實上(shang)(shang)，一(yi)些上(shang)(shang)了六(liu)代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)的(de)(de)(de)廠(chang)商(shang)反(fan)過來把更(geng)多的(de)(de)(de)資金投在(zai)五代(dai)(dai)(dai)(dai)(dai)線(xian)(xian)(xian)上(shang)(shang)，其中(zhong)道理(li)可(ke)想而(er)知。

        高端彩(cai)(cai)電(dian)(dian)的(de)(de)(de)主流尺寸(cun)(cun)是(shi)(shi)32英(ying)(ying)(ying)寸(cun)(cun)以(yi)上，主要因為高端彩(cai)(cai)電(dian)(dian)都(dou)是(shi)(shi)16：9的(de)(de)(de)屏(ping)幕比例，只有32英(ying)(ying)(ying)寸(cun)(cun)才適應(ying)中等家庭的(de)(de)(de)最(zui)低(di)住房(fang)面積。27英(ying)(ying)(ying)寸(cun)(cun)顯得(de)太小，即(ji)便是(shi)(shi)價格低(di)一些，也(ye)不可(ke)能有太大銷量，更何況用6代線(xian)(xian)做(zuo)32英(ying)(ying)(ying)寸(cun)(cun)液(ye)晶彩(cai)(cai)電(dian)(dian)和(he)5代線(xian)(xian)做(zuo)27英(ying)(ying)(ying)寸(cun)(cun)液(ye)晶彩(cai)(cai)電(dian)(dian)的(de)(de)(de)成本差不多，甚至更低(di)。所(suo)以(yi)京東方和(he)SVA的(de)(de)(de)TFT-LCD5代線(xian)(xian)投(tou)產(chan)，也(ye)不大可(ke)能用于(yu)液(ye)晶電(dian)(dian)視(shi)的(de)(de)(de)制造，主要應(ying)該是(shi)(shi)生產(chan)17英(ying)(ying)(ying)寸(cun)(cun)的(de)(de)(de)電(dian)(dian)腦監視(shi)器(qi)(qi)面板(ban)(ban)(ban)，5代線(xian)(xian)基板(ban)(ban)(ban)可(ke)以(yi)切割12片17英(ying)(ying)(ying)寸(cun)(cun)監視(shi)器(qi)(qi)用面板(ban)(ban)(ban)。毫無疑問，大陸沒(mei)有能力(li)生產(chan)大屏(ping)幕（30英(ying)(ying)(ying)寸(cun)(cun)以(yi)上）液(ye)晶電(dian)(dian)視(shi)用的(de)(de)(de)TFT-LCD面板(ban)(ban)(ban)。因此大陸的(de)(de)(de)彩(cai)(cai)電(dian)(dian)企業注定(ding)要向外采(cai)購核心的(de)(de)(de)TFT-LCD面板(ban)(ban)(ban)
