  • Patent number: 11990845
    Abstract: A secondary controller applied to a secondary side of a power converter includes a control signal generation circuit and a gate control signal generation circuit. The gate control signal generation circuit generates a gate control signal, and generates an injection signal according to the gate control signal. When a superposition voltage is less than a reference voltage, the control signal generation circuit generates a gate pulse control signal, wherein the gate pulse control signal corresponds to an output voltage of the power converter and the injection signal, the gate control signal generation circuit is further used for generating a gate pulse signal according to the gate pulse control signal, and the gate pulse signal is used for making a primary side of the power converter turned on.

  • Publication number: 20240093357
    Abstract: A semiconductor device is manufactured by modifying an electromagnetic field within a deposition chamber. In embodiments in which the deposition process is a sputtering process, the electromagnetic field may be modified by adjusting a distance between a first coil and a mounting platform. In other embodiments, the electromagnetic field may be adjusted by applying or removing power from additional coils that are also present.

  • Patent number: 11791292
    Abstract: An embedded touch panel display device includes: a display unit having a display surface and a non-display surface opposite to the display surface; a touch-control unit disposed inside the display unit; a conductive frame disposed on one side of the display unit and facing the non-display surface thereof; an insulating ink and a first conductive ink disposed on at least one sidewall of the display unit and extended to the non-display surface, in which the first conductive ink overlaps the insulating ink; and a double-sided adhesive disposed between the display unit and the conductive frame to secure them. The first conductive ink and the conductive frame are electrically connected to each other to form an electrostatic discharge path. The present invention can prevent the peripheral area of the viewed area from a blackening phenomenon induced by excessively high electrostatic voltage.

  • Patent number: 11116082
    Abstract: An improved insulation protection structure comprises a sensor film, a chip outline, a protective film, and an insulating cement layer. The chip outline is on the sensor film, the protective film is on the chip outline, the insulating cement layer is between the chip outline and the protective film. The insulating cement layer comprises at least one surface facing inward the chip outline, retracted toward the direction of the chip outline and forms a retracted region along at least one side of the sensor film. Area of the proposed retracted region is preferably no more than 20% of that of the total insulating cement layer, and the conventional issues such as sulphide corrosion are solved. The proposed insulating cement layer can be cured merely at room temperature, and widely used for adhesive materials including both a gel and film, thus characterized by wider application range and better industrial applicability.
