Display Device And Electronic Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 18671295 titled 'Display Device And Electronic Device

The patent application aims to enhance color reproduction in a display device with light-emitting elements by utilizing specific chromaticity coordinates in the CIE-XY chromaticity diagram for different pixels.

• Each picture element in the display region consists of first and second pixels with a chromaticity x-coordinate of 0.50 or more, third and fourth pixels with a chromaticity y-coordinate of 0.55 or more, and fifth and sixth pixels with chromaticity coordinates of 0.20 or less and 0.25 or less, respectively.
• The light-emitting elements in the pixels have different emission spectrums from each other, contributing to improved color accuracy and reproduction.
• By strategically selecting light-emitting elements with specific chromaticity coordinates, the display device can achieve a wider color gamut and more accurate color representation.

Potential Applications: This technology can be applied in various display devices such as TVs, monitors, smartphones, and tablets to enhance color accuracy and reproduction for a better viewing experience.

Problems Solved: The technology addresses the challenge of achieving accurate color reproduction in display devices with light-emitting elements by optimizing the chromaticity coordinates of the pixels.

Benefits: Improved color accuracy, wider color gamut, enhanced color reproduction, and better overall visual experience for users of display devices.

Commercial Applications: This technology can be utilized in the consumer electronics industry for the development of high-quality displays with superior color performance, catering to the demands of users who prioritize color accuracy in their viewing experience.

Questions about the technology: 1. How does the use of specific chromaticity coordinates in the CIE-XY chromaticity diagram improve color reproduction in display devices? 2. What are the potential implications of this technology for the consumer electronics market?

Original Abstract Submitted

To improve color reproduction areas in a display device having light-emitting elements. A display region has a plurality of picture elements. Each picture element includes: first and second pixels each including a light-emitting element which has a chromaticity whose x-coordinate in a CIE-XY chromaticity diagram is 0.50 or more; third and fourth pixels each including a light-emitting element which has a chromaticity whose y-coordinate in the diagram is 0.55 or more; and fifth and sixth pixels each including a light-emitting element which has a chromaticity whose x-coordinate and y-coordinate in the diagram are 0.20 or less and 0.25 or less, respectively. The light-emitting elements in the first and second pixels have different emission spectrums from each other; the light-emitting elements in the third and fourth pixels have different emission spectrums from each other; and the light-emitting elements in the fifth and sixth pixels have different emission spectrums from each other.
