大陸搶進中小尺寸面板產能 華映、彩晶提高戒備
2011/12/07-郭靜蓉
大陸面板廠京東方與天馬微近來持續搶攻大陸中小尺寸面板市場,尤其是藉由低價策略進攻白牌手機市場,讓台廠在該市場的既有優勢遭到夾擊,同時亦導致手機面板報價下滑,此舉促使已轉型為中小尺寸面板廠的華映與彩晶,紛紛提高警覺戒備與因應。

台廠華映與彩晶分別以6代以及5.3代面板廠大量生產手機用面板,且取得一定成果,而大陸面板廠京東方與天馬維等,近期亦開始仿效,在4.5代以及5代面板產線上,生產3吋及較小尺寸面板,導致手機面板供應量增加,報價壓力也隨之大增。

近期品牌廠在美國黑色星期五大幅降低液晶電視價格,加上大陸彩電廠也為元春假期進行銷售備貨,同時品牌廠也在醞釀提前進行新機鋪貨,至於面板廠仍持續控管產能利用率,在多重因素加總下,讓12月上旬大尺寸面板報價持穩發展。

反觀手機面板報價則非如此,由於大陸面板廠加速投入手機面板產出,導致市場競爭轉趨激烈,近期的手機面板報價也跟著下滑,根據DisplaySearch報價統計,從2011年9月下半旬至12月上半旬這段期間來看,1.8吋手機面板價格下跌0.06美元,跌幅約1.3%;2.0吋手機面板價格也下跌0.06~0.07美元,跌幅約1%;至於2.2吋手機面板價格則下跌約0.06美元,跌幅也約1%。

由於手機面板尺寸小,面板廠以較高世代廠房進行切割,產量相當驚人,以2.6吋尺寸規格為例,在3代廠(550mm x 650mm)可切112片、玻璃基板切割率為88%,4.5代線(730mm x 920mm)則可切220片、切割率達92%,而以5代線(1,100mm x 1,300mm)切割,每片玻璃基板則可產出480片面板、經濟切割率為95%,5.3代廠(1,200mm x 1,300mm)每片玻璃基板可切520片、經濟切割率為94%,6代廠(1,500mm x 1,850mm)更可切出897片,經濟切割率亦為94%。即便手機面板市場每年出貨量約可上看20億片,以TFT LCD滲透率幾達8成比重來看,如此大量產出對中小尺寸面板廠而言,在報價上勢必造成一定壓力。

近幾年隨著手機市場持續發展,手機用TFT LCD面板市場也隨之成長,DIGITIMES Research預估,2012年全球手機用面板將佔整體中小尺寸TFT LCD出貨量78.2%,不過,未來隨著AMOLED技術持續提升,加上基期已高,未來手機用TFT LCD出貨成長將趨緩,估計2011~2014年手機用TFT LCD複合成長率將為4.4%,僅稍高於整體中小尺寸TFT LCD的3.9%。

隨著技術演進,手機面板解析度不斷提高,傳統QQVGA、QCIF解析度的低階手機,已逐漸被QVGA(320 x 240)解析度所取代,未來幾年內低階主機的規格應會介於2.4~2.6吋間,至於精細度估計約可介於154~167ppi。

而智慧型手機面板解析度亦朝多樣化發展,目前低階智慧型手機面板多已採HVGA(320 x 480)解析度,中階智慧型手機面板則朝向WVGA(480 x 800),高階的智慧型手機從2012年起,估計將陸續採用精細度超過300ppi的面板。

目前多數面板廠仍採用a-Si製程生產HVGA低解析度規格的手機面板,然而一旦面板精細度超過250ppi,即很難採用a-Si技術量產,估計面板廠未來將積極在精細度250~300ppi的顯示器上採用氧化物半導體TFT,而高解析度手機面板的需求,預期未來也將持續增加。
