Description:

MicroLED is seen to be a promising technology for future display. However, traditional display technologies are making progress and are currently challenging the intrinsic performances of MicroLED for traditional display. One competitive advantage of MicroLED remains in its exceptional high radiance requiring less active light emitting surface. This unique property paves the way of disruptive display features such as embedding sensors in the same display plane to create multifunctional display. This paper tackles the question of technological co-integration of MicroLED and Organic PhotoDetector (OPD). Relying on measurement results on a custom co-integrated device, this paper provides performances of MicroLED (radiance, radiation pattern ) and OPD ( responsivity, dark-current ) to evaluate the effect of co-integration. We pay a specific attention to cross-talk coupling that remains a bottleneck of co-integration.
