  • Publication number: 20220147183
    Abstract: The present disclosure discloses a touch panel (103), including a base (10) and an electrode unit (30) arranged on the base (10), where the electrode unit (30) includes a first sub-electrode (31) and a second sub-electrode (33) that are oppositely arranged at an interval. When the electrode unit (30) is stressed, a distance or a relative area between the first sub-electrode (31) and the second sub-electrode (33) changes and causes a change in a capacitance between the first sub-electrode (31) and the second sub-electrode (33), so that pressure-sensitive touch control is implemented, ensuring touch control performance of the touch panel and lowering process control requirements. The present disclosure further provides a touch detection method.

  • Publication number: 20220100296
    Abstract: Flexible touch sensor electrode includes substrate layer metal wire layer, protective layer and lead structure. Substrate layer is made of flexible insulating material; metal wire layer is flexible film layer made of nano-metal wire, covers at least part of surface of substrate layer and is used for sensing external touch operation and generating a corresponding electrical signal; protective layer is made of flexible insulating material and covers at least part of surface of metal wire layer away from substrate layer; metal wire layer is provided with contact area for establishing electrical connection to outside; within range of contact area protective layer is all or partially removed; lead structure includes covering portion and leading-out portion, covering portion covers and directly contacts contact area to establish electrical connection and leading-out portion extends from covering portion and is used to electrically connect metal wire layer to outside.

  • Publication number: 20210321513
    Abstract: An electronic assembly includes an elastic substrate, a stretchable conductor layer, an electronic element and a compressible elastic conductor. The stretchable conductor layer is arranged on the elastic substrate, the electronic element is located on one side of the stretchable conductor layer facing away from the elastic substrate, and the stretchable conductor layer is electrically connected to the electronic element. The compressible elastic conductor is at least partially located between the stretchable conductor layer and the electronic element.

  • Publication number: 20210255717
    Abstract: The present disclosure provides a touch panel. The touch panel includes a first touch panel body (100). The first touch panel body (100) includes a substrate layer (10), a conductive layer (20), and a shielding layer (30). The conductive layer (20) is disposed on the substrate layer (10), and includes an outer side surface (201). The shielding layer (30) covers the outer side surface (201) of the conductive layer (20) to insulate the conductive layer (20) from an external environment.

  • Patent number: 7804278
    Abstract: In one embodiment, a battery management system includes a charger controller for controlling a charging current of a battery according to a status of a load which is powered by the battery, and a counter coupled to the charger controller for determining a charging time according to such status. Advantageously, a first charging current is selected when the load is off. A second charging current that is less than the first charging current is selected when the load is on. Furthermore, a frequency of the counter is set to a first frequency when the load is off. The frequency is set to a second frequency that is less than the first frequency when the load is on.
