中國(guó)屏配中國(guó)芯利亞德自主知識(shí)產(chǎn)權(quán)MicroLED驅(qū)動(dòng)芯片投入使用2019年3月，利亞德**際**面板驅(qū)動(dòng)廠家開(kāi)發(fā)新一代MicroLED驅(qū)動(dòng)芯片；2020年5月，驅(qū)動(dòng)芯片研制成功并進(jìn)行了小批量生產(chǎn)驗(yàn)證，技術(shù)水平國(guó)際**，目前已應(yīng)用于利亞德實(shí)現(xiàn)量產(chǎn)的系列MicroLED商顯產(chǎn)品中。那么，利亞德自主研發(fā)的MicroLED驅(qū)動(dòng)芯片有哪些突出優(yōu)勢(shì)？其一，高質(zhì)量顯示效果，充分發(fā)揮MicroLED的性能。該款驅(qū)動(dòng)芯片采用了“16bit+9bit”處理模式，支持DCI-P3，實(shí)現(xiàn)，顏色處理能力理論上可達(dá)370萬(wàn)億億（2的75次方），對(duì)比度提高2倍。其二，降低功耗，節(jié)能環(huán)保。該款驅(qū)動(dòng)芯片采用利亞德自主知識(shí)產(chǎn)權(quán)的共陰節(jié)能技術(shù)，對(duì)R/G/B三基色LED使用不同的電壓驅(qū)動(dòng)，使MicroLED顯示單元在功耗、封裝、散熱上取得明顯進(jìn)步。與傳統(tǒng)芯片相比，產(chǎn)品的比較大亮度功耗節(jié)省40%，平均功耗節(jié)省50%，黑屏功耗節(jié)省50%。

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）。金昌LED顯示屏公司</p><p
