Abstract: An electronic circuit including a plurality of common terminals, a first circuit, a second circuit, and a plurality of switch units is provided. The first circuit is configured to output display driving signals to data lines of a display panel via the common terminals. The second circuit is configured to receive fingerprint sensing signals from fingerprint sensing lines of the display panel via the common terminals. Each of the switch units includes a first terminal coupled to one of the common terminals and a plurality of second terminals coupled to the first circuit and the second circuit. The switch units are grouped into a plurality of groups, and each group corresponds to a fingerprint sensing channel of the second circuit.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An electronic circuit for operating with a display panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a first circuit, a second circuit, a third circuit, a first switch circuit and a control circuit. The first circuit generates display driving signals for driving the display panel. The second circuit receives fingerprint sensing signals from the fingerprint sensors. The third circuit determines a touch information according to touch sensing signals from the touch sensors. The first switch circuit includes a plurality of first switch units, each of the first switch units includes a first switch element and a second switch element. The control circuit controls the first switch circuit to transmit the display driving signals in a first time interval, controls the first switch circuit to transmit the fingerprint sensing signals in a second time interval, and controls the third circuit to receive the fingerprint sensing signals in a third time interval.

Abstract: A tailstock device for a lathe includes a carrier defining an accommodation space for accommodating a hub mount. The hub mount is turnable relative to the carrier and has two angularly displaced stage posts extending radially and outwardly for mounting first and second holders, respectively. By turning of the hub mount, a selected one of the holders is moved to a working position to aligned with a longitudinal axis of a workpiece held thereby. The tailstock device can hold a variety of workpieces, and allow adjustment of the angle and position of a workpiece held thereby.
