A sintering method includes defining a closed pattern having at least one arcuate section. A substance is applied on a substrate along the closed pattern and is sintered along the closed pattern in a first rectilinear direction. The sintering is finished in a second rectilinear direction along the closed pattern. A display device packaging method includes defining a closed pattern having at least one arcuate section. Frit is applied on a substrate of a display device along the closed pattern. A cover plate is provided on the substrate. The frit is sintered along the closed pattern. The sintering is finished in a second rectilinear direction. Then, the cover plate and the substrate of the display device are packaged.

An organic light-emitting diode fluorescent device includes an anode layer, a hole injection layer, an emissive layer, an electron injection layer, and a cathode layer. A confinement layer is disposed on at least one of an upper face and a lower face of the emissive layer. The confinement layer has a triplet energy level higher than a triplet energy level of the emissive layer. A method for producing the organic light-emitting diode fluorescent device includes providing an anode substrate as an anode layer and disposing a hole injection layer, an emissive layer, an electron injection layer, and a cathode layer on the anode layer in sequence. A confinement layer is disposed on at least one of an upper face and a lower face of the emissive layer while producing the emissive layer. The confinement layer has a triplet energy level higher than a triplet energy level of the emissive layer.

Organic light-emitting diode fluorescent device and method for producing same

An inverted top emitting device includes an TIO/Ag/ITO substrate, a cathode layer, an electron transport layer, an emissive layer, a hole transport layer, and an anode layer. The TIO/Ag/ITO substrate, the cathode layer, the electron transport layer, the emissive layer, the hole transport layer, and the anode layer are stacked in sequence. The cathode layer is made of cesium carbonate. The inverted top emitting device and its producing method provided by the present invention change the current structure of ITO/Ag/ITO/HTL/EML/ETL/Mg:Ag of the device to ITO/Ag/ITO/CsCO/ETL/EML/HTL/MoO/Ag. This avoids use of low work function metals, such as magnesium. Thus, even if the encapsulation is not satisfactory, the device is less likely to be oxidized by water and oxygen, providing the device with a longer service life.
