Abstract

The invention provides a display and an organic light-emitting diode device thereof. The organic light-emitting diode device comprises a glass substrate, an anode layer, an organic layer and a cathode layer, which are sequentially laminated, wherein the refractive index of the anode layer is greater than that of the glass substrate; and the cathode layer comprises a through hole, so that partial light emitted from the organic layer directly enters the glass substrate through the through hole to reduce the total reflection phenomenon of the contact surface of the anode layer and the glass substrate. Therefore, the light extracting rate of the organic light-emitting diode device is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic light emitting diode device and a display using the organic light emitting diode device. Background technique [0002] An organic light emitting diode device generally consists of a cathode layer, an anode layer and a light emitting layer. The cathode layer is generally made of metal materials such as Al (aluminum) and the anode is made of ITO (indium tin oxide) and other materials. Electrons and holes are respectively injected from the cathode and the anode to form excitons in the organic light-emitting layer and excite the material of the light-emitting layer to emit light. At present, most of the products in the laboratory are based on transparent anode ITO. At this time, the device structure presents a state of top emission, and the production line often places it at the bottom due to the damage of ITO evaporation to organic materials, thus adopting a botto...
