TLDR
In this paper, a light-emitting device consisting of a plurality of light sources, an optical plate, a concave structure and at least one light emitting structure was proposed.Abstract:
The invention relates to a light-emitting device, comprising a plurality of light sources, an optical plate, a plurality of concave structures and at least one light-emitting structure, wherein the optical plate is arranged above the light sources and provided with an upper surface and a lower surface The concave structures extend towards the inside of the optical plate from the upper surface of the optical plate, each concave structure is correspondingly arranged above one light source, and the lateral surface of each concave structure has at least two inclined angles The light-emitting structures are arranged on at least one of the upper surface and the lower surface of the optical plate, wherein light generated by the light sources positioned below each concave structure generates total reflection on the side surface of the concave structure and continuously carries out at least one total reflection in the optical plate and emits light out of the optical plate until coming across the light emergent structureread more

Light Emitting Device
TL;DR: By doping an organic compound functioning as an electron donor (hereinafter referred to as donor molecules) into an organics layer contacting a cathode, donor levels can be formed between respective LUMO (lowest unoccupied molecular orbital) levels between the cathode and the organic compound layer, and therefore electrons can be injected from the cathodes, and transmission of the injected electrons can also be performed with good efficiency as discussed by the authors.
