DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240276826 titled 'DISPLAY DEVICE

The patent application describes a display device with a pixel electrode layer, a light-emitting layer, a bank layer defining openings, a color conversion layer with quantum dots, and a scattering layer with scattering particles.

• Pixel electrode layer on substrate
• Light-emitting layer on pixel electrode layer
• Bank layer with openings
• Color conversion layer with quantum dots in one opening
• Scattering layer between pixel electrode and bank layer
• Scattering layer and part of color conversion layer cover exclusive parts of substrate
• Scattering layer made of base resin and scattering particles

Potential Applications: - High-quality display screens - Enhanced color accuracy in displays - Energy-efficient lighting solutions

Problems Solved: - Improved color reproduction - Reduced light leakage - Enhanced display brightness and clarity

Benefits: - Vivid and accurate color display - Energy-efficient lighting - Enhanced visual experience for users

Commercial Applications: Title: Advanced Display Technology for Enhanced Color Reproduction This technology can be used in: - High-definition televisions - Smartphone screens - Computer monitors - Advertising displays

Questions about Display Device Technology: 1. How does the scattering layer improve display quality? The scattering layer helps to reduce light leakage and enhance brightness and clarity in the display.

2. What is the role of quantum dots in the color conversion layer? Quantum dots in the color conversion layer help to improve color accuracy and vibrancy in the display.

Original Abstract Submitted

a display device includes: a pixel electrode layer disposed on a substrate, a light emitting layer disposed on the pixel electrode layer, a bank layer disposed on the light emitting layer and defining first, second, and third openings, a first color conversion layer disposed in the first opening and including first quantum dots, and a scattering layer disposed in a layer between the pixel electrode and the bank layer, such that the scattering layer and at least a part of the first color conversion layer cover mutually exclusive parts of the substrate, the scattering layer including a base resin and a plurality of scattering particles dispersed in the base resin.
