METHOD AND APPARATUS FOR MANUFACTURING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240324433 titled 'METHOD AND APPARATUS FOR MANUFACTURING DISPLAY DEVICE
The patent application describes an apparatus for manufacturing a display device using a mask assembly, magnetic force, and a deposition source.
- The apparatus includes a chamber where the process takes place.
- A mask assembly is positioned in the chamber facing the display substrate.
- A magnetic force portion applies magnetic force to the mask assembly.
- A deposition source supplies a deposition material through the mask assembly onto the display substrate.
- The mask assembly consists of a first mask layer with a mask opening and a second mask layer with an overlapping mask opening.
- The second mask layer includes a 2-1 mask portion and a 2-2 mask portion protruding towards the display substrate.
Potential Applications: - Manufacturing of display devices such as OLED screens. - Semiconductor industry for precise deposition processes.
Problems Solved: - Achieving accurate and controlled deposition on display substrates. - Enhancing the efficiency of manufacturing processes.
Benefits: - Improved quality and resolution of display devices. - Cost-effective manufacturing processes.
Commercial Applications: Title: Advanced Display Device Manufacturing Apparatus This technology can be utilized in the production of high-quality display devices for consumer electronics, medical equipment, and automotive displays. The market implications include increased demand for advanced display technologies in various industries.
Questions about the technology: 1. How does the magnetic force portion contribute to the deposition process? 2. What are the advantages of using a mask assembly in display device manufacturing?
Original Abstract Submitted
an apparatus for manufacturing a display device includes a chamber, a mask assembly disposed in the chamber and facing a display substrate, a magnetic force portion which is disposed in the chamber and applies magnetic force to the mask assembly, and a deposition source which is disposed in the chamber, faces the mask assembly and supplies a deposition material so that the deposition material passes through the mask assembly and is deposited on the display substrate, where the mask assembly includes a first mask layer in which a first mask opening is defined, and a second mask layer which is disposed on the first mask layer and in which a second mask opening overlapping the first mask opening is defined, where the second mask layer includes a 2-1mask portion, and a 2-2mask portion protruding from the 2-1mask portion toward the display substrate.
