Title:
MICRO-DISPLAY CHIP AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/093615
Kind Code:
A1
Abstract:
The present disclosure relates to the field of optical films, and in particular to a micro-display chip and a manufacturing method therefor. The micro-display chip comprises: a self-emitting layer, emitting first color light; a wavelength conversion layer, at least comprising a first wavelength conversion unit, which is superimposed with a light-emitting unit to emit second color light; and a first transmissive/reflective layer and/or a second transmissive/reflective layer, wherein the first transmissive/reflective layer is arranged between the self-emitting layer and the wavelength conversion layer; the second transmissive/reflective layer is arranged on the other surface of the wavelength conversion layer; the first transmissive/reflective layer is configured to have low reflectivity and high transmittance for the first color light and have high reflectivity and low transmittance for the second color light, and the second transmissive/reflective layer is configured to have high reflectivity and low transmittance for the first color light and have low reflectivity and high transmittance for the second color light. The micro-display chip of the present disclosure can effectively improve the absorbance and the color purity of converted light, and then thus obtain a brighter and more pure conversion spectrum.
