Display Stack with Integrated Photodetectors - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240284752 titled 'Display Stack with Integrated Photodetectors
The abstract describes an electronic device with a frame and a display stack, including OLEDs and organic photodetectors (OPDs) arranged in a specific configuration.
- The device has a frame that defines an interior volume, with a cover attached to the frame.
- The display stack includes an array of OLEDs with emissive EL regions and at least one OPD placed between the cover and an emissive EL region.
- The emissive EL regions emit light through the OPDs, allowing for efficient display functionality.
- In alternative embodiments, the OLEDs and OPDs may be stacked or interspersed with each other in the display stack.
Potential Applications: - This technology can be used in smartphones, tablets, and other electronic devices requiring high-quality displays. - It can also be applied in wearable technology, such as smartwatches, to enhance display performance.
Problems Solved: - The technology addresses the need for improved display quality and efficiency in electronic devices. - It offers a solution for integrating OLEDs and OPDs in a compact and effective manner.
Benefits: - Enhanced display performance with efficient light emission through OPDs. - Improved energy efficiency and overall device functionality.
Commercial Applications: - This technology has significant commercial potential in the consumer electronics market, particularly in the development of advanced display technologies for various devices.
Questions about the Technology: 1. How does the placement of OPDs between OLEDs improve display performance?
- The OPDs allow for efficient light emission from the OLEDs, enhancing overall display quality.
2. What are the key advantages of using OLEDs and OPDs in conjunction with each other?
- The combination of OLEDs and OPDs offers improved energy efficiency and display functionality.
Original Abstract Submitted
an electronic device includes a frame and a display stack. the frame defines a first part of an interior volume. the display stack includes a cover attached to the frame. the cover may define a second part of the interior volume. the display stack also includes an array of organic light-emitting diodes (oleds) including an array of emissive electroluminescent (el) regions, and at least one organic photodetector (opd) disposed between the cover and at least one emissive el region in the array of emissive electroluminescent regions. the at least one emissive el region emits light through the at least one opd. in alternative embodiments, the oleds may be stacked on the opds, or the oleds and opds may be interspersed with each other instead of stacked.
