摘要
本文通过分析目前显示器用的高均匀宽角度灯珠的光学要求,采用新型非朗伯(non-Lambertian)分布封装Micro-LED芯片,实现了宽光束、高均匀性的微型LED芯片光珠。分析了在不同封装倾角、封装高度、封装材料、封装支架材料、蓝宝石厚度和图案化蓝宝石衬底尺寸下,使用由不同封装材料(铜、钛、铝和银)和材料类型(完全反射和完全吸收)组成的支架模拟固定灯珠的光输出效率和出光角度的变化情况。研究发现通过调整材料、芯片和封装参数,可以得到一个、两个或三个光束,具有贴片灯珠的宽角度、高均匀性的远场光分布特性,满足当前LED和LCD的显示要求。
Through analysing the optical requirements of wide beam and high uniformity light beads,which are currently used in displays,and packaging micro Light-Emitting Diode(LED)chips with a novel non-Lambertian distribution,we realized the production of wide beam and high uniformity micro-LED chip light beads.The light output efficiency and beam angle of fixed beads were simulated using brackets made of copper,titanium,aluminium and silver,as well as materials that were completely reflecting and absorbing.The simulations were conducted at various fixture angles,packaging heights,packaging materials,sapphire thicknesses,and patterned sapphire substrate sizes.By adjusting the chip and packaging parameters,we can obtain one,two,or three light beams with Surface Mounted Device(SMD)lamp beads characteristics that provide wide angles,high uniformity,and far-field light distribution.These characteristics can meet the current display requirements for LED and LCD.
