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

This abstract first appeared for US patent application 18022154 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 after prolonged use.

The display substrate consists of a substrate, light-emitting devices, and an optical sensor positioned between adjacent light-emitting devices.
The optical sensor comprises 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 less than 2.0 eV or greater than 2.7 eV.

Potential Applications: - This technology can be applied in various display devices such as smartphones, tablets, and televisions. - It can also be used in automotive displays, wearable technology, and augmented reality devices.

Problems Solved: - Addresses the issue of unstable performance in the light-emitting layer of optical sensors. - Prevents the light-absorbing layer from becoming insensitive to light over time.

Benefits: - Improved stability and performance of the light-emitting layer. - Enhanced sensitivity of the light-absorbing layer. - Extended lifespan of display substrates.

Commercial Applications: Title: Advanced Display Substrates for Enhanced Performance This technology can be commercially used in the manufacturing of high-quality display devices for consumer electronics, automotive industry, and wearable technology markets. It offers improved performance and longevity compared to traditional display substrates.

Questions about Display Substrates: 1. How does the energy level difference between the P-type and N-type organic material layers impact the performance of the optical sensor? 2. What are the potential implications of this technology on the display industry in terms of efficiency and cost-effectiveness?
