ELECTROLUMINESCENT DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18467485 titled 'ELECTROLUMINESCENT DISPLAY DEVICE
Simplified Explanation
An electroluminescent display device described in the patent application includes an anode, organic layer, cathode, encapsulation layer, foreign material, and barrier layer to prevent penetration of moisture and oxygen, thus repairing dark spot defects and pixel defects caused by foreign substances.
- Anode over a substrate
- Organic layer on the anode
- Cathode on the organic layer
- Encapsulation layer over the cathode
- Foreign material between the anode, organic layer, cathode, and encapsulation layer
- Barrier layer over the encapsulation layer to cover the foreign material
Potential Applications
The technology described in the patent application could be applied in various display devices such as OLED screens, electronic signage, and lighting panels.
Problems Solved
This technology solves the issue of dark spot defects and pixel defects caused by foreign substances penetrating the layers of the display device.
Benefits
The benefits of this technology include improved display quality, increased longevity of the display device, and enhanced resistance to environmental factors such as moisture and oxygen.
Potential Commercial Applications
The technology could be commercialized in the manufacturing of consumer electronics, automotive displays, medical devices, and industrial equipment.
Possible Prior Art
One possible prior art for this technology could be the use of barrier layers in display devices to prevent moisture and oxygen penetration, although the specific configuration described in the patent application may be novel.
Unanswered Questions
How does the presence of the foreign material affect the overall performance of the display device?
The patent application mentions the presence of a foreign material between the layers of the display device, but it does not elaborate on how this material impacts the functionality or efficiency of the device.
What specific types of organic materials are used in the organic layer of the display device?
The patent application mentions an organic layer in the display device, but it does not specify the exact composition or properties of the organic materials used in this layer.
Original Abstract Submitted
An electroluminescent display device according to an exemplary embodiment of the present disclosure includes an anode over a substrate, an organic layer on the anode, a cathode on the organic layer, an encapsulation layer over the cathode, a foreign material present between the anode and the organic layer, the cathode, and the encapsulation layer and a barrier layer over the encapsulation layer to cover the foreign material, so that penetration of moisture and oxygen is prevented and thus, dark spot defects and pixel defects caused by foreign substances can be repaired.
