Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

Abstract: A fingerprint identification module collimating light reflected by fingertip skin patterns defines a fingerprint identification area and a peripheral area, for identifying fingerprints. The module includes a first light-shielding layer, optical sensors, a second light-shielding layer, a supporting portion, and a gap portion. The first and second light-shielding layers each define through holes (first and second through holes). Each second through hole exposes one optical sensor and is aligned with one first through hole. The supporting portion in the peripheral area bonds the first and second substrates, maintaining a certain distance between the first and second light-shielding layers. The gap portion is in the fingerprint identification area. Light reflected by a fingerprint is collimated by the first through holes, the gap portion, and the second through holes and then received as optical signals by the sensors to realize fingerprint imaging.

Abstract: A method applied to a display device for displaying images divides the display device into a first display area and a second display area. The method drives the first display area and the second display area to display images during a first driving period, and during a second driving period drives the first display area to keep displaying a most recent image. During the second driving period at least a part of the second display area is driven to display a white image, and the overall second display area is driven to accept and recognize fingerprints if and when a recognition-start signal is received during the second driving period. The first and second display areas are driven to again display images when a recognition-end signal is received during a third driving period. The display device is also provided.
