Lumileds从EQE和光方向性上处理MicroLED效率问题
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">8月29日,外网<span style="color: black;">报告</span>,近年来,Lumileds实现了Micro LED<span style="color: black;">外边</span>量子效率(EQE)性能的<span style="color: black;">明显</span><span style="color: black;">提高</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">据说</span>,EQE是LED发出的光中所含能量与注入半导体材料的电子能量之间的比率。然而,<span style="color: black;">针对</span>Micro LED而言,尤其在<span style="color: black;">表示</span>应用上EQE并<span style="color: black;">不可</span>衡量Micro LED的性能。要正确<span style="color: black;">评定</span>Micro LED的效率,还必须<span style="color: black;">测绘</span>光的方向性,光的方向性<span style="color: black;">针对</span>Micro LED<span style="color: black;">表示</span>器至关重要,<span style="color: black;">一般</span>为衡量某个<span style="color: black;">方向</span>看到的辐射或发光强度。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Lumileds的Micro LED<span style="color: black;">研发</span>高级总监Brendan Moran<span style="color: black;">暗示</span>,大<span style="color: black;">都数</span>LED从其顶面发出大部分光,尤其是薄膜类LED。当缩小薄膜LED的尺寸为Micro LED时,侧发光则将会占据整体发光表面的很大一部分。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">很强</span>尺寸LED的薄膜厚度相<span style="color: black;">针对</span>Micro LED而言在长度和宽度上得相当大,这是Micro LED从侧面发射大部分光线的关键<span style="color: black;">原由</span>,从而<span style="color: black;">引起</span>视角分布宽,并降低从顶面发射的强度。<span style="color: black;">针对</span><span style="color: black;">表示</span>器应用,即使是高EQE的Micro LED<span style="color: black;">亦</span>可能具有相对较低的光强度。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Lumileds<span style="color: black;">开发</span>团队现已<span style="color: black;">研发</span>出<span style="color: black;">拥有</span>非常理想光分布的Micro LED,该光分布近似于朗伯分布,从而实现更亮的<span style="color: black;">表示</span>效果,以及更少的能量消耗。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">据说</span>,Lumileds<span style="color: black;">开发</span>团队将于9月3日在錼创Micro LED技术论坛上介绍Micro LED最新<span style="color: black;">发展</span>和效率。(LEDinside整理)</p>
