DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240260360 titled 'DISPLAY DEVICE AND METHOD OF FABRICATING THE SAME

The patent application describes a display device with a pixel circuit layer and a light-emitting-element layer.

• The display device includes a pixel circuit layer with a base layer, a pixel circuit, and a passivation layer.
• The passivation layer has a well area and a protrusion area.
• The light-emitting-element layer is on top of the pixel circuit layer and contains a light-emitting element and a connecting electrode.
• The connecting electrode is located in the protrusion area and overlaps the well area without touching the passivation layer.
• The light-emitting element consists of a first electrode, a second electrode, and an emission part.
• The emission part comprises a hole layer, an electron layer, and an emission layer.
• The hole layer connects the first electrode to the emission layer, while the electron layer connects the second electrode to the emission layer.
• Both the hole layer and the second electrode have end portions on the connecting electrode.

Potential Applications: - This technology can be used in the manufacturing of high-quality display screens for electronic devices. - It can also be applied in the development of advanced lighting systems for various applications.

Problems Solved: - The technology addresses the need for improved display devices with enhanced pixel circuitry and light-emitting elements. - It solves the problem of ensuring proper connectivity and functionality of the emission part in the light-emitting element.

Benefits: - Enhanced display quality and performance. - Improved efficiency and reliability of light-emitting elements. - Potential for cost-effective production of display devices.

Commercial Applications: - This technology can be utilized in the production of smartphones, tablets, TVs, and other electronic devices requiring high-quality displays. - It can also be integrated into lighting systems for commercial and residential use.

Questions about the Technology: 1. How does the design of the connecting electrode improve the functionality of the light-emitting element? 2. What are the potential cost savings associated with implementing this technology in display devices?

Original Abstract Submitted
