DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240233435 titled 'DISPLAY DEVICE
The abstract describes a display device with a display panel that includes an image display area and a non-display area. The image display area contains display pixels with light-emitting elements and pixel driving units, as well as light-sensing pixels with photo-detecting units in a fingerprint sensing area.
Key Features and Innovation:
- Display panel with image display and non-display areas
- Display pixels with light-emitting elements and pixel driving units
- Light-sensing pixels with photo-detecting units in a fingerprint sensing area
- Light-sensing reset driver supplying reset signals to sense driving units
- Fingerprint scan driver sequentially supplying fingerprint scan signals to sense driving units
Potential Applications: This technology could be used in devices requiring fingerprint sensing capabilities integrated into display panels, such as smartphones, tablets, and laptops.
Problems Solved: The technology addresses the need for seamless integration of fingerprint sensing functionality within display panels, eliminating the need for separate fingerprint sensors.
Benefits:
- Enhanced security with integrated fingerprint sensing
- Streamlined design without the need for additional sensors
- Improved user experience with convenient fingerprint authentication
Commercial Applications: This technology could be highly valuable in the consumer electronics market, particularly for manufacturers looking to enhance the security features of their devices.
Prior Art: Readers interested in prior art related to this technology could explore patents or research papers on integrated fingerprint sensors in display panels.
Frequently Updated Research: Researchers in the field of display technology and biometric authentication may be conducting studies on improving the efficiency and accuracy of integrated fingerprint sensors in display panels.
Questions about Integrated Fingerprint Sensing in Display Panels: 1. How does the technology ensure the accuracy and reliability of fingerprint authentication? 2. What are the potential challenges in implementing integrated fingerprint sensors in display panels?
Original Abstract Submitted
a display device comprises a display panel comprising an image display area and a non-display area, display pixels comprising light-emitting elements in the image display area and pixel driving units connected to the light-emitting elements, light-sensing pixels comprising photo-detecting units in a fingerprint sensing area in the image display area, and sense driving units connected to the photo-detecting units, a light-sensing reset driver configured to supply reset signals to the sense driving units of the light-sensing pixels for at least each horizontal line among the light-sensing pixels in response to a line select signal from a display driving circuit; and a fingerprint scan driver configured to sequentially supply a fingerprint scan signal to the sense driving units of the light-sensing pixels in response to a fingerprint scan control signal from the display driving circuit.
