對(duì)于方案的選擇，利亞德給出原因。COB方案當(dāng)前面臨的**主要問(wèn)題還是墨色一致性和拼接模塊化的問(wèn)題。就間距方面而言，COB受限的是芯片尺寸和基板材料，比如采用FR4基板及0408的LED芯片，比較低可實(shí)現(xiàn)；但如果采用BT板和更小的LED，則可突破該間距；但BT板價(jià)格卻是普通FR4材料的3-6倍。而SMD當(dāng)前比較低可實(shí)現(xiàn)，燈珠尺寸和貼片良率是限制這一尺寸往下走的主因。行家說(shuō)產(chǎn)業(yè)研究中心認(rèn)為，多合一方案是承接了分立器件外觀和顯示一致性好的優(yōu)點(diǎn)，適應(yīng)分立器件的成熟分選技術(shù)，讓?xiě)?yīng)用端貼片后保證色差一致性。而從產(chǎn)業(yè)鏈協(xié)作效益上看，切實(shí)解決了在短期內(nèi)快速量產(chǎn)的問(wèn)題，且大部分設(shè)備可直接沿用傳統(tǒng)分立器件1010的機(jī)臺(tái)，制程工藝大多相近。下游顯示屏廠也依然保留了SMT工序，且貼片成本更低、PCB布線更經(jīng)濟(jì)簡(jiǎn)單。青海LED顯示屏銷售西藏LED顯示屏_甘肅LED顯示屏生產(chǎn)廠家-蘭州菲凡電子科技有限公司。</p><div

揭曉：利亞德MicroLED顯示屏技術(shù)路線：近期，利亞德***在國(guó)內(nèi)專業(yè)展會(huì)上，展出了MicroLED顯示屏，是目前業(yè)界可量產(chǎn)點(diǎn)密度/分辨率比較高的**產(chǎn)品之一。而在線下實(shí)品展出之前，業(yè)界早已對(duì)該款產(chǎn)品的量產(chǎn)有所耳聞，并且對(duì)于利亞德作為L(zhǎng)ED顯示屏**，會(huì)選擇何種技術(shù)路線來(lái)實(shí)現(xiàn)LED顯示屏極為好奇。？芯片是正裝還是倒裝？基板采用PCB還是玻璃？封裝是SMD、四合一還是COB方案？驅(qū)動(dòng)IC直接采購(gòu)還是自主研發(fā)？巨量轉(zhuǎn)移層面效率和良率如何？……接下來(lái)我們一一揭曉。倒裝芯片據(jù)利亞德展會(huì)現(xiàn)場(chǎng)人員介紹，目前利亞德LED產(chǎn)品全部采用倒裝芯片，芯片尺寸均＜100μm（89*150μm，）。從目前LED芯片結(jié)構(gòu)上，主要有三種流派，**常見(jiàn)的是正裝結(jié)構(gòu)，此外，還有垂直結(jié)構(gòu)和倒裝結(jié)構(gòu)。
