Abstract

A transparent light emitting diode (LED) panel with a 16 × 16 multicolor LED array for a signage application is proposed and studied based on experimental and simulation results. As a transparent electrode, oxide/metal/oxide (OMO) trilayers with various Al interlayer thicknesses were fabricated and characterized using an established a simulation model. Using commercial ray tracing optical and SPICE simulation tools, we designed the LED panel and investigated in its optical and electrical properties. Moreover, in order to resolve the waveguide effect and voltage drop issue across the panel, we integrated additional optical structures and various OMO width into the design. The results show that the OMO electrode interconnects and proposed design considerations are pivotal aspects toward achieving transparent LED digital signage applications.
