“… 9 The spreading thermal resistance will increase further with the increase of the injection level. 10 When the proximate μLEDs work together, such as the pixels in the high brightness micro-display, 11,12 the complexity of the lighting and the visible light communication (VLC), 1 the thermal transport will become more difficult, since the heating μLED will be surrounded by other heavily heating neighbors. In these cases, the design of current spreading, pixel size and geometry may be not effective to obtain the low junction temperature.…”
