Dual-sided display panel and method of manufacturing same

A dual-sided display panel, comprising:

• a first organic light-emitting unit and a second organic light-emitting unit disposed in a stacked arrangement;
• wherein the first organic light-emitting unit comprises a plurality of first pixel definition layers and a plurality of blue pixel light-emitting layers, a first gap is defined between adjacent ones of the first pixel definition layers, and the blue pixel light-emitting layers are filled in the first gaps;
• wherein the second organic light-emitting unit comprises a plurality of second pixel definition layers, a plurality of red pixel light-emitting layers, and a plurality of green pixel light-emitting layers, a second gap is defined between adjacent ones of the second pixel definition layers, and the red pixel light-emitting layers and the green pixel light-emitting layers are filled in the second gaps and are sequentially disposed and spaced apart from each other in a direction from the blue pixel light-emitting layer to the first pixel definition layer, wherein each of the red pixel light-emitting layers comprises a first portion and a second portion adjoining each other, each of the green pixel light-emitting layers comprises a third portion and a fourth portion adjoining each other, the first portion and the third portion are disposed corresponding to the first pixel definition layers, and the second portion and the fourth portion are disposed corresponding to the blue pixel light-emitting layers;
• and
• wherein each of the first pixel definition layer and the second pixel definition layer is made of colorless polyimide, and each of the blue pixel light-emitting layer, the red pixel light-emitting layer, and the green pixel light-emitting layer has a length between 20 microns (μm) and 25 μm.

A method of manufacturing a dual-sided display panel, comprising:

• forming a first organic light-emitting unit, and the first organic light-emitting unit comprising a first surface and a second surface disposed opposite to each other, a plurality of first pixel definition layers, a plurality of blue pixel light-emitting layers, and a first gap defined between adjacent ones of the first pixel definition layers, wherein the blue pixel light-emitting layers are filled in the first gaps;
• forming a second organic light-emitting unit, and the second organic light-emitting unit comprising a plurality of second pixel definition layers, a plurality of red pixel light-emitting layers, a plurality of green pixel light-emitting layers, and a second gap defined between adjacent ones of the second pixel definition layers, wherein the red pixel light-emitting layers and the green pixel light-emitting layers are filled in the second gaps and are sequentially disposed and spaced apart from each other in a direction from the blue pixel light-emitting layer to the first pixel definition layer, wherein each of the red pixel light-emitting layers comprises a first portion and a second portion adjoining each other, and each of the green pixel light-emitting layers comprises a third portion and a fourth portion adjoining each other;
• and
• attaching the first organic light-emitting unit to the second organic light-emitting unit such that the first organic light-emitting unit and the second organic light-emitting unit are staggered, so that the first organic light-emitting unit and the second organic light-emitting unit are disposed in a stacked arrangement, the first portion and the third portion are disposed corresponding to the first pixel definition layers, and the second portion and the fourth portion are disposed corresponding to the blue pixel light-emitting layers.
