摘要: A simulation scheme was developed to explore the light distribution of full-color micron-scale light-emitting diode (LED) arrays. The influences substrate thickness, patterning, and cutting angle on several important features, such as field pattern, extraction efficiency, color variation, were evaluated numerically. An experiment conducted; results consistent with for a 225 × 125 µm2 miniLED those an 80 microLED. Based results, efficiency LED devices increases by 67.75% over without substrate. 113.55% when additional patterned design is used green blue chips. calculated large Δu′v′ can be low 0.015 devices.
