DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240244892 titled 'DISPLAY DEVICE

The display device described in the patent application consists of multiple light emitting devices arranged on a substrate, each comprising a first electrode, an emission layer, and a second electrode.

• The device includes a pixel defining layer with multiple openings that overlap the first electrode in a plan view.
• An encapsulation layer covers the light emitting devices and has multiple first openings that overlap the pixel defining layer in a plan view.
• A bank is placed on the encapsulation layer, overlapping the first openings in a plan view, and includes multiple second openings that overlap the light emitting devices in a plan view.
• Inside the second openings, there are a first color conversion layer, a second color conversion layer, and a transmission layer.
• A spacer, containing a colored material, is positioned on the bank.

Potential Applications: - This technology can be used in the development of high-resolution displays for electronic devices. - It can be applied in the manufacturing of OLED screens for televisions, smartphones, and other gadgets.

Problems Solved: - The technology addresses the need for improved color accuracy and brightness in display devices. - It helps in reducing light leakage and enhancing the overall performance of the display.

Benefits: - Enhanced color reproduction and brightness in display screens. - Improved efficiency and performance of light emitting devices. - Reduction in light leakage and better overall display quality.

Commercial Applications: "Advanced Display Technology for High-Resolution Screens: Market Implications and Commercial Uses"

Questions about the technology: 1. How does the placement of the color conversion layers inside the second openings contribute to the overall display quality? 2. What are the potential cost implications of implementing this technology in mass-produced electronic devices?
