  • Patent number: 11972077
    Abstract: A resetting system includes a driver that controls a touchscreen, the driver including a driver communication interface that defines a bus for transferring a transfer signal; and an on-screen display (OSD) device that generates an OSD signal representing a predetermined reset image in response to a predetermined event, the OSD signal superimposing over pixels and graphics data to be rendered on the touchscreen; and a host that transfers the transfer signal to or from the driver, the host including a host communication interface that defines the bus for transferring the transfer signal to or from the driver.

  • Publication number: 20240111377
    Abstract: A touch detection circuitry includes an analog-to-digital converter (ADC), a controller, and a packet generator. The ADC is arranged to convert touch signals of a touch panel from analog form into digital form. The controller is electrically connected to the ADC, and is configured to calculate at least one coordinate point and at least one touch size respectively corresponding to at least one touch event on the touch panel based on the touch signals. The packet generator is electrically connected to the controller, and is configured to encapsulate the at least one coordinate point and the at least one touch size into a touch data packet.

  • Publication number: 20210327745
    Abstract: A pickup and contact device is adapted to be connected to a moving device to move a picked-up electronic element to an electrical testing zone. The moving device pressurizes the electronic element through the pickup and contact device, so that a contact point of the electronic element stably contacts a contact pad of the electrical testing zone. The pickup and contact device includes a main body including a base and a contact portion and a plurality of heat dissipation fins disposed at two opposite sides of the base. The contact portion is adapted to pick up the electronic element and to move the electronic element to the electrical testing zone along with the moving device. When the electronic element is tested in the electrical testing zone, heat emitted from the electronic element is adapted to be transmitted out through the heat dissipation fins of the main body.
