DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240203351 titled 'DISPLAY DEVICE AND METHOD OF DRIVING THE SAME
The abstract describes a display device with a unique pixel that includes both a light emitting element and a light sensing element, along with a scan driver, panel driving circuit, and readout circuit.
- The display panel contains a pixel with a light emitting element and a sensor with a light sensing element.
- The scan driver sends a scan signal to drive both the pixel and the sensor in response to a scan control signal.
- The panel driving circuit outputs the scan control signal.
- The readout circuit generates switching signals based on the scan control signal and outputs a fingerprint sensing signal corresponding to the sensor's signal in response to the switching signals.
Potential Applications: - Biometric security systems - Touchscreen devices with enhanced functionality - Medical devices for monitoring vital signs
Problems Solved: - Improved security through biometric authentication - Enhanced user interaction with touchscreens - More accurate and reliable sensor readings in medical devices
Benefits: - Increased security and privacy protection - Enhanced user experience with responsive touchscreens - Improved accuracy and reliability in sensor readings
Commercial Applications: Title: "Advanced Biometric Display Technology for Enhanced Security" This technology could be used in smartphones, tablets, laptops, and other devices requiring secure access control and user authentication.
Questions about the technology: 1. How does this display device improve security measures compared to traditional methods? - This technology enhances security by combining a light emitting element and a light sensing element in each pixel, allowing for more accurate and reliable biometric authentication. 2. What are the potential challenges in implementing this technology on a large scale? - The main challenges could include cost of production, compatibility with existing devices, and ensuring seamless integration with different operating systems and software platforms.
Original Abstract Submitted
a display device is disclosed that includes a display panel, a scan driver, a panel driving circuit, and a readout circuit. the display panel includes a pixel that includes a light emitting element and a sensor that includes a light sensing element. the scan driver outputs a scan signal for driving the pixel and the sensor in response to a scan control signal. the panel driving circuit outputs the scan control signal. the readout circuit generates switching signals based on the scan control signal and outputs a fingerprint sensing signal corresponding to a sensing signal received from the sensor in response to the switching signals.
