DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240298464 titled 'DISPLAY DEVICE

The abstract of the patent application describes a display device with a unique capping layer structure for thin film encapsulation.

• The display device includes a substrate, a display element, a capping layer, and a thin film encapsulation layer.
• The capping layer consists of a first, second, and third capping layer, with the second layer having a higher refractive index than the first layer.
• The second capping layer is 30nm to 60nm thick, providing specific optical properties to the device.

Potential Applications: - This technology can be used in the manufacturing of high-quality display devices such as OLED screens. - It can enhance the durability and performance of electronic displays in various consumer electronics.

Problems Solved: - The capping layer structure addresses issues related to moisture and oxygen permeation, which can degrade display performance over time. - It improves the overall longevity and reliability of display devices.

Benefits: - Enhanced display quality and longevity. - Improved resistance to environmental factors. - Potential cost savings in device maintenance and replacements.

Commercial Applications: - This technology can be applied in the production of smartphones, tablets, TVs, and other electronic devices with display screens.

Questions about the technology: 1. How does the unique capping layer structure improve the performance of display devices?

  - The capping layer structure provides enhanced protection against environmental factors, leading to improved display longevity and quality.

2. What are the specific benefits of using a multi-layer capping structure in thin film encapsulation?

  - The multi-layer capping structure offers superior barrier properties, reducing the impact of moisture and oxygen on display performance.

Original Abstract Submitted

a display device includes: a substrate; a display element on the substrate; a capping layer on the display element; and a thin film encapsulation layer on the capping layer, wherein the capping layer includes: a first capping layer on the display element; a second capping layer on the first capping layer, the second capping layer having a refractive index greater than that of the first capping layer; and a third capping layer on the second capping layer, the third capping layer having a refractive index smaller than that of the second capping layer, wherein the second capping layer has a thickness of 30 nanometers (nm) to 60 nm.
