  • Publication number: 20240045535
    Abstract: A force sensing processing method of a touchpad is provided. The comparison values obtained by subtracting the force induction quantities of different frames are used to determine whether the achievement conditions are met. If it is met, a processing step is executed to respond the event to be triggered by the changing trend of the user's force. When the force changes rapidly and the force sensing amount cannot be quickly returned to the originally set trigger threshold value, the force changing trend detected by the comparison values are be used to provide the processing steps in real time, so as to improve the user experience.

  • Publication number: 20230394269
    Abstract: A card having a fingerprint sensor and a manufacturing method of the same are provided. The fingerprint sensor is disposed between a substrate and a protection layer. The protection layer has a first area and a second area thereon. The roughness of the second area is smaller than the roughness of the first area. The second area corresponds to the sensing area of the fingerprint sensor. When the user's finger is wet, the second area may effectively keep the water from remaining on it. Thus, the water does not affect the effect of fingerprint sensing.

  • Patent number: 11836317
    Abstract: A touchpad and its force-sensing data correction method are provided. The touchpad has a force-sensing layer and a touch-sensing layer. The force-sensing layer has multiple force-sensing points. The touch-sensing layer has multiple touch-sensing points. One force-sensing point corresponds to n touch-sensing points. The force-sensing information received by the force-sensing layer is adjusted by using the touch-sensing information received by the touch-sensing layer, so that the resolution of the adjusted force-sensing information is higher than the resolution of the original received force-sensing information. In this way, the purpose of calibrating the force-sensing information is achieved, so as to improve the accuracy of determining the force applied by the object during the operation of the touchpad.

  • Patent number: 11837011
    Abstract: A button module with vibration feedback and fingerprint sensing, a fingerprint sensing module for the same, and a control method for the same are provided. The fingerprint sensing module has a fingerprint sensing unit stacked on a vibration unit. When the fingerprint sensing module detects a fingerprint, the control unit or a host of an electronic device determines whether the fingerprint is authenticated. If it is not authenticated, the vibration unit is activated, so that the user realizes that the authentication is not passed in real time through the vibration. Then the user may quickly change another finger or move the finger's position to speed up the authentication process. This can prevent users from waiting to improve user experience.

  • Patent number: 11328528
    Abstract: 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.

  • Publication number: 20220058359
    Abstract: A fingerprint sensing module has a fingerprint sensor and a cover. The main color layer and the pattern layer are arranged between the cover and the fingerprint sensor. The pattern layer constitutes a predetermined pattern that is used to present the pattern of the button. The both sides of the main color layer are flush with both sides of the pattern layer, so that the capacitance variations in the corresponding pattern layer and the main color layer pass through the medium with the same thickness, and have an approximate capacitance variation mode. Thus, the sensed fingerprint image truly reflect the detected fingerprint image without being affected by the preset pattern, and a pattern layer with a certain thickness is used to enhance the color saturation presented by the predetermined pattern.

  • Patent number: 11048954
    Abstract: The present invention relates to a fingerprint enrollment method and an electronic device for performing the fingerprint enrollment method. A fingerprint sensor of the electronic device senses the fingerprint to generate the fingerprint images. The processor of the electronic device determines if M qualified fingerprint images are acquired or the number of times the finger touches the fingerprint sensor reaches N. When any of the above conditions is satisfied, the operation of sensing fingerprint is stopped. After that, the processor uses the fingerprint images to generate fingerprint enrollment information to complete the fingerprint enrollment process. Based on the disclosure of the present invention, the user can complete the fingerprint enrollment process regardless of whether the user uses spiral enrollment or pressing enrollment.

  • Patent number: 10969912
    Abstract: A capacitive sensing and sampling circuit and method thereof are disclosed. The capacitive sensing and sampling circuit has a voltage source, a sensing unit and a detecting circuit. The detecting unit has a first sensing output unit, a second sensing output unit and a sampling unit. The first and second sensing output units are electrically connected to an output of the sensing unit and the sampling unit. Therefore, by increasing the number of alternatively sensing the capacitive sensing component to obtain more capacitive signals, the number of sampling the sensed capacitive signal is relatively increased. Therefore, the white noise interference for the capacitive sensing and sampling circuit is effectively suppressed, so the signal-to-noise ratio is increased and accuracy of detecting coordinates of the touch object is increased.

  • Publication number: 20210089163
    Abstract: A touch device and an operation method thereof is provided. By determining whether the operating event of the touch device or its touchpad satisfies an exclusion condition, the command triggered when the touchpad is pressed is determined to be ignored or not. Therefore, the corresponding command triggered by pressing the touchpad downward is automatically excluded when it does not want to be triggered. Therefore, the user can naturally disable the function of the corresponding command, which is executed when the pressing module is triggered, during use without using other controls, thereby improving the convenience of use.
