Abstract
An electronic device with fingerprint sensing function including a display panel, a fingerprint sensing module and a supporting frame are provided. The fingerprint sensing module includes a light source and an image sensor. The light source is configured to emit an illuminating light. The supporting frame is disposed between the display panel and the fingerprint sensing module for supporting the display panel. The supporting frame includes a first plane facing the display panel, a second plane facing the fingerprint sensing module, and an oblique through hole between the first plane and the second plane. The illuminating light is guided toward a sensing object above the display panel through the oblique through hole.

An electronic device with fingerprint sensing function comprising:
- a display panel;
- a fingerprint sensing module, comprising a light source configured to emit an illuminating light and an image sensor;
- and
- a supporting frame, disposed between the display panel and the fingerprint sensing module for supporting the display panel, and comprising a first plane facing the display panel, a second plane facing the fingerprint sensing module, and an oblique through hole between the first plane and the second plane, and
- wherein the illuminating light is guided toward a sensing object above the display panel through the oblique through hole,
- wherein the oblique through hole comprises a first opening area at the first plane and a second opening area at the second plane, and a first distance between a center of the first opening area and a first projection center of the image sensor at the first plane is larger than a second distance between a center of the second opening area and a second projection center of the image sensor at the second plane.
A fingerprint sensing module installed in an electronic device, wherein the electronic device comprising a display panel and a supporting frame supporting the display panel, the supporting frame having a plurality of oblique through holes for light guiding, and the fingerprint sensing module comprising:
- a substrate;
- a plurality of light sources disposed on the substrate;
- an image sensor disposed on the substrate;
- a lens for concentrating lights diffused by a sensing object positioned above the display panel;
- and
- a lens holder fixed on the substrate, for supporting the lens;
- wherein the fingerprint sensing module is installed below the supporting frame, and lights illuminating by the light sources are guided through the oblique through holes of the supporting frame and pass through the display panel to a sensing object,
- wherein each of the oblique through holes comprises a first opening area exposed to a first plane of the supporting frame facing to the display panel and a second opening area exposed to a second plane of the supporting frame facing to the fingerprint sensing module, and a first distance between a center of the first opening area and a first projection center of the image sensor at the first plane is larger than a second distance between a center of the second opening area and a second projection center of the image sensor at the second plane.
