Method for manufacturing a color conversion optoelectronic device by localized deposition of photoluminescent particles on predefined conversion zones with structured surface potential

Abstract

The invention relates to a method for manufacturing an optoelectronic device (1) with a diode array (20), comprising the following steps: producing an electret layer (30) having conversion zones (Zc) separated in pairs by a spacing zone (Ze) with zero surface potential, where each conversion zone (Zc) is formed of a plurality of elementary zones, called polarized zones (32), with non-zero surface potential, separated in pairs by an elementary zone, called unpolarized zone (33), with zero surface potential, such that the conversion zone (Zc) has a structured surface potential; producing color conversion pads (P) by contacting the electret layer (30) with a colloidal solution (S) containing photoluminescent particles (p).
