APPARATUS AND METHOD FOR MANUFACTURING DISPLAY DEVICE, AND MASK ASSEMBLY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240324435 titled 'APPARATUS AND METHOD FOR MANUFACTURING DISPLAY DEVICE, AND MASK ASSEMBLY
The apparatus described in the patent application is a device for manufacturing a display device. It includes a mask assembly, a magnetic force portion, and a deposition source inside a chamber.
- The mask assembly faces the display substrate and consists of a first mask layer with a mask opening and a second mask layer with a metal layer and an inorganic layer.
- The magnetic force portion applies a magnetic force to the mask assembly.
- The deposition source supplies a deposition material that passes through the mask assembly and is deposited on the display substrate.
Potential Applications: - This technology can be used in the manufacturing of display devices such as OLED screens. - It can also be applied in the production of touchscreens and other electronic displays.
Problems Solved: - The apparatus provides a precise and efficient way to deposit materials on display substrates. - It ensures accurate patterning and alignment of the deposition material.
Benefits: - Improved manufacturing process for display devices. - Enhanced quality and performance of display screens. - Cost-effective production method for electronic displays.
Commercial Applications: Commercial applications of this technology include the mass production of high-quality display devices for consumer electronics, automotive displays, and medical equipment.
Questions about the technology: 1. How does the magnetic force portion enhance the manufacturing process of display devices? 2. What are the specific advantages of using a mask assembly with multiple layers in this apparatus?
Original Abstract Submitted
an apparatus for manufacturing a display device includes a mask assembly arranged inside a chamber and facing a display substrate, a magnetic force portion arranged inside the chamber and applying a magnetic force to the mask assembly, and a deposition source which is arranged inside the chamber, faces the mask assembly, and supplies a deposition material that passes through the mask assembly and is deposited on the display substrate. the mask assembly includes a first mask layer including a first mask opening, and a second mask layer disposed on the first mask layer. the second mask layer includes a metal layer including a metal opening corresponding to the first mask opening, and an inorganic layer including an inorganic opening corresponding to the first mask opening and the metal opening. in a plan view, a width of the metal opening is greater than a width of the inorganic opening.
