摘要： A smart card with a fingerprint sensing system, includes a controller and a fingerprint sensing device. When the fingerprint sensing device senses a fingerprint to generate a fingerprint frame data, the controller enters a sleep mode, and when the controller reads the fingerprint frame data, the fingerprint sensing device stops sensing the fingerprint. Since operations of sensing the fingerprint and reading the fingerprint frame data do not occur at the same time, the high current condition can be avoided so as to decrease power consumption.

摘要： A lighting touchpad includes a circuit board and a light-emitting element. The circuit board has a touch sensing area, and a plurality of first sensor cells and at least one second sensor cell are formed in the touch sensing area. Each of the first sensor cells has the same first areas, and each of the at least one second sensor cell has a second area smaller than the first area. The light-emitting element is disposed in the touch sensing area and adjacent to the at least one second sensor cell. The configuration of the present invention is helpful to reduce a touch dead zone (also be called an inactive area) of the lighting touchpad.

摘要： A touch sensing method for a display with touch device having an image display period, which includes multiple execution time sections. Each execution time section has a display time division and a blank time division. A display procedure is executed in each display time division. A communicating procedure is executed in one of the blank time division. In the communicating procedure, an uplink signal is provided by the common electrodes for a first object to receive. Thus, the display with touch device has more time to detect more different kinds of touch objects.

摘要： A screen control module of a mobile electronic device has at least one controller formed on a circuit board. The circuit board has multiple solder pads formed on the circuit board and respectively aligning along a first direction and a second direction. An amount of the solder pads along the first direction is greater than that along the second direction. The controller is formed by an integrated circuit with a package, and the aspect ratio of the package is not less than 2. The package has multiple electrical contacts respectively aligning along a length direction and a width direction. Each electrical contact aligns with and is electrically connected to a corresponding solder pad. Accordingly, the screen control module mounted within a side frame of a display of the mobile electronic device can increase the aspect ratio to meet the demand for narrowing the side frame of the display.
