UNDER-DISPLAY ULTRASONIC FINGERPRINT SENSORS FOR FOLDABLE DISPLAYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18486914 titled 'UNDER-DISPLAY ULTRASONIC FINGERPRINT SENSORS FOR FOLDABLE DISPLAYS
Simplified Explanation
The patent application describes an apparatus that includes an ultrasonic sensor stack, a foldable display stack, and a transmission enhancement layer. The foldable display stack consists of a display stiffener and display stack layers, which form one or more display stack resonators. These resonators are designed to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in a specific frequency range. The transmission enhancement resonator may include the display stiffener and the transmission enhancement layer, and in some cases, it may also include a portion of the ultrasonic sensor stack.
- The apparatus includes an ultrasonic sensor stack, a foldable display stack, and a transmission enhancement layer.
- The foldable display stack consists of a display stiffener and display stack layers.
- The display stack layers form one or more display stack resonators.
- The resonators are configured to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in a specific frequency range.
- The transmission enhancement resonator may include the display stiffener and the transmission enhancement layer.
- In some cases, the transmission enhancement resonator may also include a portion of the ultrasonic sensor stack.
- The purpose of the invention is to improve the transmission of ultrasonic waves in a specific frequency range.
Potential Applications:
- Mobile devices with foldable displays that utilize ultrasonic sensors for various functions.
- Medical devices that require precise ultrasonic sensing and display capabilities.
- Industrial applications where ultrasonic sensing and display integration is needed.
Problems Solved:
- Enhances the transmission of ultrasonic waves in a specific frequency range.
- Improves the performance and accuracy of ultrasonic sensing in devices with foldable displays.
Benefits:
- Improved functionality and accuracy of ultrasonic sensing in devices with foldable displays.
- Enhanced user experience through better performance of ultrasonic sensing technology.
- Enables the integration of ultrasonic sensing and display capabilities in a single device.
Original Abstract Submitted
An apparatus may include an ultrasonic sensor stack, a foldable display stack and a transmission enhancement layer. The foldable display stack may include a display stiffener and display stack layers. The display stack layers may form one or more display stack resonators configured to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in a first ultrasonic frequency range. In some implementations, a transmission enhancement resonator may include the display stiffener and the transmission enhancement layer. In some examples, the transmission enhancement resonator may include at least a portion of the ultrasonic sensor stack. The transmission enhancement resonator may be configured to enhance the ultrasonic waves transmitted by the ultrasonic sensor stack in the first ultrasonic frequency range.
