  • Publication number: 20240019741
    Abstract: An LCD display module uses an ingenious gradient flexible printed circuit to produce a larger and thinner display. The gradient flexible printed circuit connects a driver integrated circuit between a printed circuit board assembly and an ITO circuit on a glass substrate. The gradient flexible printed circuit has a narrow, minor end connected to the ITO circuit and a wider, major end connected to the printed circuit board assembly. Because the gradient flexible printed circuit has different end widths, the gradient flexible printed circuit permits reduced spacing of electronic components in proximity of the narrower minor end. Signaling between the electronic components is improved, and electromagnetic shielding is reduced. The gradient flexible printed circuit also has a smaller dimensional stack, thus allowing for a larger display viewing area and a thinner display.

  • Patent number: 11842003
    Abstract: A touch panel device includes a face plate, a bracket, and a PCB. The face plate receives a contact. The bracket includes a permanent magnet affixed to a surface of the bracket. The PCB is positioned proximate to the bracket such that a surface of the PCB is adjacent to the bracket. The PCB includes a Hall sensor collocated proximate to the permanent magnet. The touch panel circuit is coupled to the Hall sensor. When the contact is received at the face plate, the PCB moves closer to the bracket. In response, the touch panel circuit receives a voltage from the Hall sensor, determines a force associated with the contact based upon the voltage, and triggers a haptic feedback response in the bracket.

  • Publication number: 20230352808
    Abstract: An information handling system with a wireless charging system or wireless antenna may include a processor; a memory; a power management unit (PMU), an antenna controller to provide instructions to a radio to cause an antenna to transceive wirelessly with a network, or a wireless charging controller to schedule the wireless charging at a charging coil, where the antenna or charging coil are part of a twice-molded modular antenna including: the antenna a charging coil, an antenna holder onto which the antenna is insert molded, and an antenna cover that is molded onto the antenna or charging coil for interference at an antenna window edge surface of a chassis cover of the information handling system.

  • Patent number: 11720177
    Abstract: A touch panel device includes a face plate, a force-feedback device, and a touch panel circuit. The face plate receives at a first surface a contact with the face plate. The force-feedback device includes a PCB affixed by a first surface of the PCB to a second surface of the face plate. The PCB includes a first metallic ring on a second surface of the PCB. The piezo disc includes a piezoelectric wafer and a second metallic ring. The piezo disc is adjacent to the second surface of the PCB. The touch panel circuit is coupled to the first metallic ring, the second metallic ring, and the piezoelectric wafer. The touch panel circuit determines a capacitance between the first metallic ring and the second metallic ring, determines a force associated with the contact based upon the capacitance, and triggers a haptic feedback response in the piezoelectric wafer.
