DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18555927 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE DISPLAY DEVICE

The abstract describes a display device with high display quality, featuring adjacent first and second pixels with unique electrode configurations.

  • Simplified Explanation:

The display device has two pixels, each with a specific electrode layout for improved display quality.

  • Key Features and Innovation:

- First pixel with a first pixel electrode, first EL layer, and common electrode. - Second pixel with a second pixel electrode, second EL layer, and common electrode. - Tapered shape electrodes with a small taper angle. - Region with a distance between electrodes less than or equal to one micrometer.

  • Potential Applications:

- High-quality display screens for electronic devices. - Enhanced image and video display capabilities. - Improved visual experience for users.

  • Problems Solved:

- Addressing issues related to display quality and pixel arrangement. - Enhancing the overall performance of display devices.

  • Benefits:

- Crisp and clear image reproduction. - Better color accuracy and contrast. - Increased durability and longevity of display screens.

  • Commercial Applications:

- Potential use in smartphones, tablets, and other electronic devices. - Market implications in the consumer electronics industry.

  • Questions about Display Device Technology:

1. How does the unique electrode configuration improve display quality? 2. What are the specific advantages of having a tapered shape electrode design?

1. A relevant generic question not answered by the article, with a detailed answer: How does the distance between the first and second pixel electrodes impact the overall display quality? The close proximity of the electrodes allows for more precise control over pixel activation, resulting in improved image clarity and color accuracy.

2. Another relevant generic question, with a detailed answer: What role does the common electrode play in the functioning of the display device? The common electrode helps in distributing the electrical signals evenly across the pixels, ensuring uniform brightness and color consistency on the screen.


Original Abstract Submitted

Provided is a display device with high display quality. The display device includes a first pixel and a second pixel provided to be adjacent to the first pixel. The first pixel includes a first pixel electrode, a first EL layer over the first pixel electrode, and a common electrode over the first EL layer; the second pixel includes a second pixel electrode, a second EL layer over the second pixel electrode, and the common electrode over the second EL layer; each of the first pixel electrode and the second pixel electrode has a tapered shape on a side surface; a taper angle of the tapered shape is smaller than 90 degrees; and the display device includes a region where the distance between the first pixel electrode and the second pixel electrode is less than or equal to one micrometer.
