href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>,国内所有的LED TV面板来源全部进口,其中有部分opencell的模式,但是背光模组仍是采用指定购买的方式。从中国大陆地区LED面板供应来源来看,以2010年第一季度为例,主要供货来源为LGDisplay,AMLCD,AUO,CPT,其中CPT供货多数为小尺寸。而从全球LED面板产值来看,日本厂商目前为市场领导者,台湾和韩国厂商积极扩大产值。由此来看,LEDTV面板产业市场集中度非常高,未来的LEDTV市场的竞争格局主要受限于厂商的资源分配情况。<br /> <br /> LED作为LCDTV背光源的关键零组件,占据了LCD电视面板总成本的20%,其本身拥有完善而错综复杂的供应链,并且核心<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>属于长交货周期<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>,LED的稳定供应不免成为面板和整机厂商头痛的事情。从LED背光源产业链的结构看,主要有外延制程,芯片制程,芯片封装三个阶段,分属产业上中下游。而扩散片,光学膜和芯片为三大关键组件。由于市场集中度高,在市场需求旺季和需求爆发期,往往出现材料紧缺的状况。目前扩散片和晶粒都呈现不同程度的缺货状况。<br /> <br /> 芯片方面,预估全球MOCVD数量逐步增加,其中以韩国和台湾厂商最为积极,Samsung,LGInnotek以及AUO旗下的Lextar都将增加MOCVD机台数量至目前的2~3倍。到2010年底,预计全球高亮度 LED晶粒月产能将接近200亿,但目前市场应用仍以移动终端产品和汽车<a href="http://light.oecr.com" target="_blank" class="relatedlink">照明</a>用为主,前两者的应用比重高达55%,但TV用背光源应用比重总体仍将难突破 20%,因此背光源缺货状况的缓解将需要较长时间。[/link]</td></tr></table> </div> <div id="comment_804969" class="cm"> </div> <div
