An optical fingerprint sensing module includes an image sensing device, a light source and a light shielding structure. The image sensing device is configured to sense light transmitted from a fingerprint of a finger on a display panel. The image sensing device includes a light sensing plane having a first geometric center. The light source includes a light emitting plane having a second geometric center. The first geometric center is separated from the second geometric center by a distance from 2 mm to 20 mm. The light shielding structure is disposed between the image sensing device and the light source. In examples, the optical fingerprint sensing module further includes a field angle controller to constrain light pass there through with a field angle of 5-60 degrees. A display device including an optical fingerprint sensing module is disclosed herein as well.

Optical fingerprint sensing module and display device with optical fingerprint detection

An optical device including a first substrate, a light source, a second substrate, an image capturing device, a lens module and a lens holder is provided. The light source outputs a first light beam. The second substrate includes a first surface and a second surface opposite to the first surface and closer to the first substrate. A scattered light beam which is generated by the first light beam entering an object touching the first surface of the second substrate and scattered in the object is a second light beam. The image capturing device receives a third light beam. The third light beam is the second light beam normally incident to the second surface and transmitted to the image capturing device. The lens module focuses the third light beam to be captured by the image capturing device. The lens holder is located between the light source and the image capturing device.

Optical device for fingerprint collection

An optical device including a first substrate, a light source, a second substrate, an image capturing device, a microstructure layer, and an infrared pass layer is provided. The light source is disposed on the first substrate. The second substrate is disposed above the first substrate. The second substrate includes a first surface and a second surface opposite to the first surface. The image capturing device is disposed on the first substrate to receive a light beam, which is originated from scattered light beams scattered by an object touching the first surface of the second substrate. The microstructure layer is disposed on the first surface of the second substrate. The microstructure layer is adapted to increase a light beam, which is scattered by the object and transmitted to the image capturing device. The infrared pass layer is adapted to pass the infrared light.

A control method for a first device of an inter-integrated circuit (IC) system including a microcontroller unit (MCU), includes receiving a first indication from the MCU of the IC system, wherein the first indication configures the first device from a slave mode to a master mode; polling the first device itself for status information of the first device when the first device is in the master mode; determining whether the status information of the first device matches a target status after polling; and determining to perform a parameter adjustment on a second device of the IC system when determining that the status information of the first device matches the target status.
