DISPLAY SUBSTRATE AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240284690 titled 'DISPLAY SUBSTRATE AND DISPLAY DEVICE
The patent application relates to display substrates and display devices in the field of display technology. It addresses the issue of unstable performance of the light-emitting layer of the optical sensor in existing display substrates, as well as the light-absorbing layer becoming insensitive to light over time.
- The display substrate includes a substrate, light-emitting devices, and an optical sensor between adjacent light-emitting devices.
- The optical sensor consists of a p-type organic material layer and an n-type organic material layer stacked together.
- The energy level difference between the highest occupied molecular orbital of the p-type layer and the lowest unoccupied molecular orbital of the n-type layer is crucial, being less than 2.0 eV or greater than 2.7 eV.
Potential Applications: - OLED displays - Electronic devices with optical sensors - Lighting applications
Problems Solved: - Unstable performance of light-emitting layers - Insensitivity of light-absorbing layers over time
Benefits: - Improved stability and sensitivity of optical sensors - Enhanced performance of display substrates
Commercial Applications: Title: Enhanced Display Substrates for Optimal Performance in Electronic Devices This technology can be used in various electronic devices, such as smartphones, tablets, and televisions, to improve display quality and longevity.
Questions about the technology: 1. How does the energy level difference between the organic material layers impact the performance of the optical sensor? - The energy level difference affects the efficiency and sensitivity of the optical sensor, ensuring optimal performance in detecting light. 2. What are the key advantages of using organic material layers in display substrates? - Organic material layers offer flexibility, efficiency, and improved performance in display technology.
