DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17887973 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes a display panel, scan lines, sensing lines, pixels, and photo sensors. It also includes a scan driver, a timing controller, and a readout circuit.
- The display panel consists of scan lines, sensing lines, pixels, and photo sensors.
- The scan driver outputs scan signals to the scan lines based on a scan control signal.
- The timing controller generates the scan control signal and sends it to the scan driver.
- The readout circuit receives light sensing signals from the photo sensors through the sensing lines.
The patent application explains that the timing controller can adjust the frame frequency of the scan control signal based on the mode of operation:
- In the first mode, when the display panel is used to display an image, the frame frequency is set to a first value.
- In the second mode, when the photo sensors are used to sense a fingerprint, the frame frequency is set to a different value.
Potential applications of this technology:
- Mobile devices with fingerprint sensors integrated into the display panel.
- Biometric authentication systems that use the display panel to both display information and capture fingerprints.
Problems solved by this technology:
- Simplifies the integration of fingerprint sensors into display devices.
- Allows for more efficient use of the display panel by dynamically adjusting the frame frequency.
Benefits of this technology:
- Improved user experience with seamless integration of fingerprint sensing and display functionality.
- Enhanced security with biometric authentication capabilities.
- Cost savings by eliminating the need for separate fingerprint sensors.
Original Abstract Submitted
A display device comprises a display panel which comprises scan lines, sensing lines, pixels electrically connected to each of the scan lines, and photo sensors electrically to each of the scan lines and the sensing lines, a scan driver which outputs scan signals to the scan lines according to a scan control signal, a timing controller which outputs the scan control signal to the scan driver, and a readout circuit which receives light sensing signals of the photo sensors from the sensing lines. The timing controller sets a frame frequency of the scan control signal to a first frame frequency in a first mode in which the display panel displays an image. The timing controller sets the frame frequency of the scan control signal to a second frame frequency in a second mode in which the photo sensors sense a fingerprint.
