1. 1. 1. 1. Unanswered Questions

1. 1. 1. How does the display device ensure accurate fingerprint recognition?

The display device uses photo-detecting units in the fingerprint sensing area to capture fingerprint patterns, which are then processed for authentication. However, the specific algorithms or technologies used for fingerprint recognition are not detailed in the abstract.

1. 1. 1. What impact does the integration of a fingerprint sensor have on the overall display performance?

While the abstract mentions the integration of a fingerprint sensor into the display panel, it does not provide information on any potential trade-offs in display performance or quality that may result from this integration. Further details on how the fingerprint sensing area affects the display's functionality would be beneficial for a comprehensive understanding of the technology.

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.
