Abstract
The display device comprises: a display panel displaying an image, a light blocking layer disposed under the display panel and comprising a plurality of holes, a fingerprint sensing layer disposed under the light blocking layer and comprising a plurality of fingerprint sensors receiving reflected light passing through the plurality of hole and generating a sensing signal, and a sensor driver controlling operations of the plurality of fingerprint sensors. The sensor driver compares fingerprint data generated based on a sensing signal generated from reflected light by a user's fingerprint with prestored reference data to generate a fingerprint image.
Claims16
A display device, comprising:
- a display panel displaying an image;
- a light blocking layer disposed under the display panel and comprising a plurality of holes;
- a fingerprint sensing layer with sensing areas comprising a plurality of fingerprint sensors receiving reflected light passing through the plurality of holes and generating a sensing signal, wherein each of the sensing areas includes a central area with concentrated information about the user's fingerprint;
- and a peripheral area surrounding the central area;
- and
- a sensor driver controlling operations of the plurality of fingerprint sensors,
- wherein the sensor driver compares fingerprint data generated based on the sensing signal with prestored reference data to generate a fingerprint image,
- wherein the sensor driver receives the sensing signal corresponding to the user's fingerprint, and merges data of the peripheral area of each of the sensing areas and data of the central area of another sensing area adjacent to the corresponding sensing area to generate the fingerprint data.
