Stacked display unit and its fabrication method

Abstract

This invention discloses a stacked display unit and its fabrication method, belonging to the field of display technology. The stacked display unit includes: a driving backplane with a pixel driving array; a pixel layer comprising multiple sub-pixel layers stacked on a pixel region of the driving backplane, each sub-pixel layer including sub-pixel units, each sub-pixel unit electrically connected to the pixel driving array, the orthographic projections of each sub-pixel unit on the driving backplane not overlapping, and sub-pixel units in different layers emitting different colors of light; and a reflective structure formed within the pixel layer, used to reflect the lateral light emitted by each sub-pixel unit, causing the light emitted by each sub-pixel unit to be emitted towards the side away from the driving backplane. The stacked sub-pixel units do not obstruct each other in the light emission direction, and the upward propagation of light emitted from the bottom is not easily blocked; simultaneously, the reflective structure utilizes the lateral light emitted by each sub-pixel unit to achieve upward reflection, improving the light emission of the stacked full-color structure. none
