Electronic pen, touch control screen, chargeable electronic pen system and charging method thereof

Abstract

The invention relates to charging technologies, and discloses an electronic pen, a touch control screen, a chargeable electronic pen system and a charging method thereof. In the system and the method, the chargeable electronic pen system contains the electronic pen and the touch control screen; a first antenna arranged in the electronic pen sends a first electromagnetic signal to the touch control screen, and a second antenna arranged in the touch control screen receives the first electromagnetic signal; the electronic pen further comprises a power source unit; the power source unit is connected with the first antenna; the second antenna is further used to send a second electromagnetic signal; the first antenna receives the second electromagnetic signal, and outputs the signal to the power source unit, so as to charge the power source unit. Therefore, the abrasion of the electronic pen is reduced, the electronic pen can also be used during charging, and a user can have good experience.

Description

technical field [0001] The invention relates to charging technology, in particular to electronic pen charging technology. Background technique [0002] A touchscreen portfolio typically consists of a touchscreen and an electronic pen. Wherein, the touch screen includes a second antenna to receive the electromagnetic signal emitted by the first antenna built in the electronic pen, and the touch screen displays the operation of the electronic pen on the touch screen according to the received electromagnetic signal. [0003] Electronic pens include: battery-powered electronic pens and battery-free electronic pens. For battery-type electronic pens, currently used batteries are dry batteries or other replaceable rechargeable batteries. However, dry cells have a limited service life and need to be replaced when they are depleted; other replaceable rechargeable batteries also need to be removed and recharged when they are depleted. [0004] However, on the one hand, replacing th...

Problems solved by technology

However, dry batteries have a limited lifespan and need to be replaced when depleted; other replaceable rechargeable batteries also need to be removed and recharged when depleted

[0004] However, on the one hand, replacing the battery increases the wear and tear of the electronic pen; on the other hand, other replaceable rechargeable batteries cannot use the electronic pen while charging, that is, the electronic pen cannot be charged.
