DISPLAY SUBSTRATE AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18632520 titled 'DISPLAY SUBSTRATE AND DISPLAY DEVICE

The abstract describes a display substrate and method for manufacturing it, as well as a display device, all related to the display technology field. The display substrate consists of a base substrate, an electroluminescent device layer, and a light-absorbing layer. The electroluminescent device layer emits initial light of a first color, which transforms into target light after passing through the light-absorbing layer. The emission spectrum of the initial light is wider than that of the target light, resulting in a display device with a wider color gamut.

Display substrate with electroluminescent device layer and light-absorbing layer
Initial light emitted by the electroluminescent device transforms into target light after passing through the light-absorbing layer
Emission spectrum of initial light is wider than that of target light
Wider color gamut in the display device
Improved color performance and visual experience

Potential Applications: - High-quality displays for smartphones, tablets, and TVs - Enhanced color accuracy for professional monitors and medical imaging devices - Improved color reproduction for digital signage and advertising displays

Problems Solved: - Limited color gamut in traditional display devices - Inaccurate color representation in certain applications - Reduced visual experience due to narrow emission spectra

Benefits: - Enhanced color performance and accuracy - Improved visual experience for users - Greater flexibility in display design and applications

Commercial Applications: Title: Enhanced Color Gamut Display Substrates for High-End Devices This technology can be utilized in various commercial applications such as high-end smartphones, professional monitors, and digital signage displays. The wider color gamut and improved color accuracy provided by this display substrate can attract customers looking for superior visual experiences in their devices.

Questions about Display Substrates: 1. How does the wider color gamut in display substrates impact user experience? The wider color gamut enhances color accuracy and vibrancy, providing users with a more visually appealing display.

2. What are the potential market implications of using display substrates with improved color performance? Display substrates with improved color performance can cater to a wider range of industries, including entertainment, design, and medical imaging, where color accuracy is crucial.

Original Abstract Submitted

Disclosed are a display substrate and a method for manufacturing the same, and a display device, belonging to the technical field of display. The display substrate includes: a base substrate, an electroluminescent device layer on the base substrate, and a light-absorbing layer on a light-emitting side of the electroluminescent device layer, wherein the electroluminescent device layer is configured to emit initial light of a first color, wherein the initial light forms target light after passing through the light-absorbing layer, and a full width at half maximum of an emission spectrum of the initial light is greater than a full width at half maximum of an emission spectrum of the target light. According to the present disclosure, the display device is provided with a wider color gamut.
