技術(shù)與成本的博弈MiniLED顯示屏如何突圍？▼▼然而，具備量產(chǎn)能力并不意味著有大規(guī)模商業(yè)化的能力，超小間距顯示屏要突圍商顯等新的應(yīng)用市場(chǎng)，技術(shù)、成本均需要進(jìn)一步考量。一方面，由于LED顯示屏模組點(diǎn)間距不斷縮小，其面臨著封裝工藝難度增大、良率降低等問(wèn)題，對(duì)封裝技術(shù)要求更高、更嚴(yán)格；另一方面，據(jù)LEDinside估算，2019年全球*為10-20億RMB之間，占所有顯示屏規(guī)模比重在5%以內(nèi)，廠商尚未大規(guī)模量產(chǎn)，價(jià)格昂貴是普及速度緩慢的主要原因。因此，成本與技術(shù)成為了MiniLED顯示屏能否進(jìn)入其他新應(yīng)用領(lǐng)域的重要考量，如何突圍，關(guān)鍵在于成本與技術(shù)兩方面所能提供的解決方案。MD封裝異軍突起技術(shù)與成本皆獲勝▼▼目前，市面上LED顯示屏產(chǎn)品的封裝方案主要有三種，分別為：SMD封裝方案、COB封裝方案和IMD封裝方案，那么，這三種封裝方案各有哪些特點(diǎn)？?SMD封裝方案SMD封裝方案是為了達(dá)到更小間距而衍生的方案，由單個(gè)或多個(gè)LED芯片焊在帶有塑膠“杯形”外框的金屬支架上，然后在塑膠外框內(nèi)灌封液態(tài)環(huán)氧樹(shù)脂或者有機(jī)硅膠，***高溫烘烤成型，完成后再切割分離成單個(gè)表貼封裝器件。但隨著器件尺寸越來(lái)越小，單顆SMD封裝技術(shù)對(duì)線路精度要求高（如PCB精度、切割精度）。甘肅蘭州LED顯示屏生產(chǎn)led顯示屏——蘭州菲凡電子科技有限公司_專業(yè)led顯示屏廠家。</p><div

COB封裝方案COB封裝方案采用的是集成封裝技術(shù)，是一種將裸芯片用導(dǎo)電或非導(dǎo)電膠粘附在互連基板上，然后進(jìn)行引線鍵合實(shí)現(xiàn)其電器連接。COB封裝技術(shù)具備可靠性高、整屏組裝效率高、面光源出光柔和等明顯優(yōu)勢(shì)，理論上可應(yīng)用于毫米級(jí)的任意間距，但是其所需的材料昂貴，此外為解決顯示和外觀一致性的問(wèn)題，需要付出更高的成本。IMD封裝方案IMD封裝方案，是一種根據(jù)LED顯示電路原理將相互關(guān)聯(lián)的多個(gè)像素集成封裝在一個(gè)封裝體中，全新的集成封裝技術(shù)。其既承接了單顆SMD封裝方案的低成本、色彩/外觀一致性好等優(yōu)點(diǎn)，又汲取了COB封裝方案的防磕碰、可靠性高的精華，有效解決了拼接縫、漏光、維修等問(wèn)題。**重要的是，IMD封裝方案可**降低顯示屏廠的使用成本，如，PCB只需6層2階，SMT效率是SMD的3倍以上。而且對(duì)于封裝廠而言，IMD封裝方案可以沿用常規(guī)小間距封裝產(chǎn)線的大多數(shù)設(shè)備，對(duì)資本投入的要求相對(duì)較低。綜合各種因素可得，IMD封裝方案可為L(zhǎng)ED微顯示產(chǎn)業(yè)探索路上提供**出色的封裝技術(shù)解決方案。

一、首先做邊框根據(jù)現(xiàn)有的一個(gè)正在制作的小屏舉例做一個(gè)結(jié)構(gòu)。從市場(chǎng)上買4*4的方鋼4根2*2的4根(6米長(zhǎng))，先用4*4的方鋼做一個(gè)田字架(可根據(jù)自己情況定制)，大邊框的尺寸為4850mm*1970mm，因?yàn)樾∵吙騼?nèi)的尺寸才是裝屏的尺寸，方鋼為40mm，所以是這個(gè)尺寸。焊的時(shí)候用鋼角尺盡可能的焊好90度角。中間那個(gè)尺寸不重要。田字架做好后，開(kāi)始在上面焊小方鋼，小方鋼的內(nèi)部尺寸為4810mm*1930mm四角及中部用剩下的4*4方鋼切成小段焊上去方便包不銹鋼。小連框做好后開(kāi)始焊背條，前兩塊用板量著焊，找到尺寸后一直往下焊就行了。背條是40mm寬的，長(zhǎng)度為1980mm左右，兩頭能夠著好焊就行。焊好后的邊框(照的是背面)邊框就可以拿到大廳內(nèi)安裝了。墻頂部做好兩個(gè)角鋼掛鉤。西藏

9．實(shí)際使用中，光強(qiáng)計(jì)算常常采用比較容易測(cè)繪的數(shù)據(jù)單位或變向使用。對(duì)于LED顯示屏這種主動(dòng)發(fā)光體一般采用CD/平方米作為發(fā)光強(qiáng)度單位，并配合觀察角度為輔助參數(shù)，其等效于屏體表面的照度單位勒克司；將此數(shù)值與屏體有效顯示面積相乘，得到整個(gè)屏體的在比較好視角上的發(fā)光強(qiáng)度，假設(shè)屏體中每個(gè)像素的發(fā)光強(qiáng)度在相應(yīng)空間內(nèi)恒定，則此數(shù)值可被認(rèn)為也是整個(gè)屏體的光通量。一般室外LED顯示屏須達(dá)到4000CD/平方米以上的亮度才可在日光下有比較理想的顯示效果。普通室內(nèi)LED，比較大亮度在700～2000CD/平方米左右。單個(gè)LED的發(fā)光強(qiáng)度以CD為單位，同時(shí)配有視角參數(shù)，發(fā)光強(qiáng)度與LED的色彩沒(méi)有關(guān)系。單管的發(fā)光強(qiáng)度從幾個(gè)mCD到五千mCD不等。LED生產(chǎn)廠商所給出的發(fā)光強(qiáng)度指LED在20mA電流下點(diǎn)亮，比較好視角上及中心位置上發(fā)光強(qiáng)度比較大的點(diǎn)。封裝LED時(shí)頂部透鏡的形狀和LED芯片距頂部透鏡的位置決定了LED視角和光強(qiáng)分布。一般來(lái)說(shuō)相同的LED視角越大，比較大發(fā)光強(qiáng)度越小，但在整個(gè)立體半球面上累計(jì)的光通量不變。10．當(dāng)多個(gè)LED較緊密規(guī)則排放，其發(fā)光球面相互疊加，導(dǎo)致整個(gè)發(fā)光平面發(fā)光強(qiáng)度分布比較均勻。在計(jì)算顯示屏發(fā)光強(qiáng)度時(shí)，需根據(jù)LED視角和LED的排放密度。西藏led電子顯示屏_蘭州菲凡電子科技有限公司_全彩LED顯示屏實(shí)惠廠家。甘肅蘭州LED顯示屏生產(chǎn)廠家</p><p
