RESIN COMPOSITION, DISPLAY APPARATUS INCLUDING THE RESIN COMPOSITION, AND PORTABLE ELECTRONIC DEVICE INCLUDING THE RESIN COMPOSITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240319769 titled 'RESIN COMPOSITION, DISPLAY APPARATUS INCLUDING THE RESIN COMPOSITION, AND PORTABLE ELECTRONIC DEVICE INCLUDING THE RESIN COMPOSITION

The display apparatus described in the patent application consists of a display panel with a display element, a cover window, and an adhesive member between the display panel and the cover window.

• The adhesive member includes a first adhesive layer and a second adhesive layer, with the second adhesive layer containing a resin composition comprising various compounds such as acrylamide-based, ester-based, and acrylate-based compounds, along with an initiator.
• The ester-based compound in the second adhesive layer consists of a first ester-based compound with a heterocycloalkyl group and a second ester-based compound with an aryl group.
• The acrylate-based compound in the second adhesive layer includes a urethane acrylate-based compound, a first acrylate-based compound with a bicyclic structure, and a second acrylate-based compound with a linear alkyl group.

Potential Applications: - This technology can be used in the manufacturing of display devices such as smartphones, tablets, and monitors. - It can also be applied in the automotive industry for heads-up displays and infotainment systems.

Problems Solved: - Provides a strong and durable bond between the display panel and the cover window. - Ensures the protection of the display element from external elements such as dust and moisture.

Benefits: - Enhanced display device durability and longevity. - Improved display clarity and visibility. - Cost-effective manufacturing process for display devices.

Commercial Applications: - This technology can be utilized by electronics manufacturers to improve the quality and reliability of their display products, leading to increased customer satisfaction and brand loyalty.

Questions about the technology: 1. How does the resin composition in the adhesive member contribute to the overall performance of the display apparatus? 2. What are the specific advantages of using a two-layer adhesive system in this context?
