Abstract

Provided in the present application is an active stylus. The active stylus comprises a stylus point mechanism, and a conductive member that is arranged around the stylus point mechanism, wherein the stylus point mechanism comprises a conductive refill that is used for transmitting a signal, and an isolation member that is sleeved outside the conductive refill.

In addition, since the conductive refill is made of a soft conductive material, the conductive refill does not scratch the touch-control panel during a contact process with the foldable touch-control panel, thereby avoiding generating scratches on the foldable touch-control panel. Further provided in the present application are a touch-control system provided with an active stylus, and an interaction method of a touch-control system.

FIG. 1 is a schematic three-dimensional structure diagram of the active stylus 100 according to the first embodiment of the present application, and FIG. 2 is the tip of the active stylus 100 in FIG. 1 . 3 is a schematic exploded perspective view of the active stylus 100 in FIG. 2; FIG. 4 is a schematic perspective view of the active stylus 100 in FIG. 3; FIG. 3 is a further exploded perspective view of the active stylus 100 ; FIG. 6 is a further exploded perspective view of the active stylus 100 in FIG. 4 . The active stylus 100 provided by the first embodiment of the present application includes a casing 20 , a main board 30 arranged in the inner cavity of the casing 20 , a pen tip mechanism 40 , and a conductive member 50 arranged around the pen tip mechanism 40 . , and a positioning mechanism 60; the pen tip mechanism 40 includes a conductive pen core 42 for sending signals and a spacer 44 set outside the conductive pen core 42, and the conductive pen core 42 is made of soft conductive material ; The conductive member 50 is used to receive signals, and the conductive member 50 is sleeved outside the isolation member 42, so that the conductive refill 42 is isolated from the conductive member 50, that is, the conductive refill 42 It is not conductive with the conductive member 50 . The positioning mechanism 60 is used for installing the pen tip mechanism 40 to the inner cavity of the casing 20, and the conductive pen core 40 is electrically connected to the main board 30 in the casing 20 through the positioning mechanism 60; The component 50 is electrically connected to the main board 30 through wires 501 .

When the active stylus 100 is used in conjunction with an electronic device such as a touch panel, the conductive member 50 receives the uplink signal sent by the touch panel, and conducts it to the main board 30 through the wire 501 , and the main board 30 The downlink signal is generated according to the scanning frequency program code stored in the memory module; the top of the conductive refill 42 contacts the touch panel, and the downlink signal generated by the motherboard 30 is transmitted to the touch panel through the conductive refill 42. control panel, so that the active stylus 100 performs a touch operation on the touch panel, that is, the handshake information between the conductive refill 42 of the active stylus 100 and the touch panel is completed.

Signal.

In other embodiments, the touch panel may also be, but not limited to, a screen of an electronic device such as a foldable tablet computer and a foldable display screen.

When the active stylus and the foldable touch panel in the prior art are configured and used, the rigidity of the cover film covering the light-emitting surface of the foldable touch panel is relatively low. The metal refill is in direct contact with the foldable touch panel, and the metal refill is easy to scratch the foldable touch panel. In order to prevent the foldable touch panel from being scratched, the active touch panel is generally The outside of the metal refill of the pen is covered with a soft cover; however, the soft cover attenuates the downlink signal amount of the metal refill, which affects the handshake between the active stylus and the flexible screen. The pairing of the active stylus and the foldable touch panel may fail. The active stylus 100 in the present application includes a conductive refill 42 made of a soft conductive material, and the conductive refill 42 is electrically connected to the main board 30 . Therefore, the end of the conductive refill 42 can directly Touch the foldable touch panel to perform touch operations. Since the conductive refill 42 directly contacts the foldable touch panel, under the same pen tip driving voltage, the downlink signal of the conductive refill 42 is relatively strong, which can satisfy the requirements of the active stylus 100 and all other devices.

The conductive refill 42 in this application is made of a conductive polymer, and the hardness of the conductive refill 42 can be adjusted as required. Specifically, the hardness of the conductive refill 42 is based on the hardness of the soft conductive material. The ratio of each component is adjusted, for example, when the conductive refill 42 is made of conductive plastic, the softness and hardness are adjusted by the composition ratio of the resin in the conductive plastic and conductive substances such as gold, silver, copper, nickel and other fine powders; such as When the conductive refill 42 is made of conductive plastic, the hardness is adjusted by the composition ratio of raw rubber such as silicone rubber, neoprene rubber, nitrile rubber, etc. and conductive material such as gold, silver, copper, nickel and other fine powders. The hardness of the conductive refill 42 is adjusted according to its corresponding different types of touch panels; specifically, if the conductive refill 42 is matched with a hard-screen touch panel, the hardness of the conductive refill 42 can be higher; if the conductive refill 42 is matched with the foldable touch panel, the hardness of the conductive refill 42 is relatively low to prevent the conductive refill 42 from scratching the foldable touch panel.

When writing on the layer, the resistance is relatively large, which causes the soft sleeve set on the outside of the metal refill to be easily worn, so that the metal refill is easily exposed and scratches are generated on the cover film layer. The conductive refill 42 of the present application is made of a conductive material whose hardness can be adjusted, and the conductive refill 42 can be adjusted to a suitable hardness, so that the conductive refill 42 is not easily worn, and will not be covered in the Scratches are generated on the film layer, and the conductive refill 42 is in direct contact with the cover film layer, so that the downlink signal of the conductive refill 42 is strong.

In this embodiment, the spacer 44 is made of insulating polymer, and the hardness of the spacer 44 can be adjusted as required, that is, according to the spacer 44 corresponding to different types of screens. Preferably, the insulating material made of the spacer 44 may be, but not limited to, insulating rubber, insulating resin, insulating silicone, insulating plastic, and the like.

Preferably, the conductive refill 42 and the spacer 44 are integrally formed by two-color injection molding, that is, the conductive refill 42 and the spacer 44 are respectively injection-molded into the same set of molds using soft conductive materials and insulating materials. The conductive refill 42 after injection molding is integrated with the spacer 44, and the conductive refill 42 is made of a flexible conductive material, and the spacer 44 is made of an insulating material. During the two-color injection molding process, the hardness of the conductive refill 42 and the spacer 44 can be adjusted as required, and the shapes of the conductive refill 42 and the spacer 44 can also be designed as needed.
