APPARATUS FOR MANUFACTURING DISPLAY APPARATUS AND METHOD OF MANUFACTURING DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240324281 titled 'APPARATUS FOR MANUFACTURING DISPLAY APPARATUS AND METHOD OF MANUFACTURING DISPLAY APPARATUS

The patent application describes an apparatus for manufacturing a display apparatus, which includes a mask assembly and a deposition source.

  • The mask assembly consists of a mask frame with an opening area, a first mask with a first opening, and a second mask with multiple second openings overlapping the first opening.
  • Each of the second openings has a corner curvature radius of 6 μm or less, ensuring precise deposition on the display substrate.

Potential Applications:

  • This technology can be used in the production of high-resolution displays for electronic devices.
  • It can also be applied in the manufacturing of OLED screens and other advanced display technologies.

Problems Solved:

  • The apparatus addresses the challenge of achieving accurate and uniform deposition on display substrates.
  • It ensures the production of displays with sharp images and vibrant colors.

Benefits:

  • Improved display quality and resolution.
  • Enhanced manufacturing efficiency and consistency in display production.

Commercial Applications:

  • This technology can be valuable for display manufacturers looking to enhance the quality and performance of their products.
  • It has the potential to impact the consumer electronics market by enabling the production of cutting-edge displays.

Questions about the technology: 1. How does the corner curvature radius of the second openings contribute to the precision of deposition? 2. What are the specific advantages of using a multi-layered mask assembly in display manufacturing processes?


Original Abstract Submitted

an apparatus for manufacturing a display apparatus includes: a mask assembly facing a display substrate; and a deposition source facing the mask assembly on a side opposite the display substrate. the mask assembly includes: a mask frame having an opening area; a first mask on the mask frame and having a first opening; and a second mask on the first mask and having a plurality of second openings overlapping with the first opening and positioned within a circumference of the first opening in a plan view. a corner curvature radius of each of the second openings is 6 �m or less.
