Display Stack with Integrated Photodetectors - A simplified explanation of the abstract
This abstract first appeared for US patent application 18653007 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 frame of the device defines an interior volume, with the display stack attached to it.
- The display stack consists of OLEDs with emissive EL regions and OPDs placed between the cover and the EL regions.
- The EL regions emit light through the OPDs, allowing for efficient light emission and detection.
- In alternative embodiments, the OLEDs and OPDs may be stacked or interspersed with each other.
Potential Applications: - This technology could be used in smartphones, tablets, and other electronic devices with displays. - It may also find applications in wearable technology, such as smartwatches and fitness trackers.
Problems Solved: - The technology addresses the need for efficient light emission and detection in electronic devices. - It provides a compact and integrated solution for OLED displays with photodetection capabilities.
Benefits: - Improved energy efficiency and performance in electronic devices. - Enhanced functionality with integrated photodetection capabilities.
Commercial Applications: - This technology could be valuable for consumer electronics manufacturers looking to enhance the performance of their devices. - It may also have applications in the healthcare industry for wearable health monitoring devices.
Questions about the technology: 1. How does the placement of OPDs between OLEDs improve the performance of the display? 2. What are the potential challenges in integrating OLEDs and OPDs in electronic devices?
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.
