Description

Pen stylus

The invention relates to a pen capacitor stylus, in particular to a pen stylus that triggers a touch pen by a pen capacitor, and changes a device for changing the charge of the touch device by a human body capacitive touch method.

At present, the touch of the resistive and capacitive touch panels on the market is achieved by means of a finger and a stylus. The operation principle is to change the charge of the touch panel by a direct human body capacitance or a capacitive pen indirectly relying on a human body capacitance. Trigger panel function. However, with a finger or a capacitive pen, it often feels that the resolution is insufficient, and the triggering effect cannot be triggered correctly.

In view of this, the inventor of the present invention developed a pen-capacitive stylus which can effectively improve the defects mentioned in the above-mentioned prior art based on his own creativity and continuous experimentation.

The main purpose of the present invention is to provide a pen-capacitive stylus that triggers a panel in a pen-capacitor manner, which can improve the touch resolution of the finger and the capacitive pen. The system includes: a capacitor head, the pen capacitor provides the function of triggering the touch panel; a step-down circuit module is a step-down circuit module to reduce the voltage to the working voltage; and a shell carries the pen capacitor and the step-down circuit module group.

The first figure is a schematic structural view of a pen stylus of the present invention; The second figure is a circuit block diagram of the present invention.

In order to more clearly describe a specific capacitive stylus proposed by the present invention, a preferred embodiment of the present invention will be described in detail below with reference to the drawings. Please also refer to the first picture. They are respectively a schematic structural view of a pen capacitor stylus of the present invention. The capacitive stylus pen comprises: a capacitor head 1, a pressing circuit module 2 and a sheath 3; the capacitor head 1 can selectively use a polymer conductive to make it have a function of capacitance; The voltage circuit module 2 is connected to the capacitor head 1 and is stepped down to the working voltage required for the capacitance of the pen capacitor head. The connection mode is a battery 21, a connection voltage circuit 22, and a capacitor 23, a capacitor; The pen case 3 is a module that carries a pen capacitor and a step-down circuit. The step-down circuit module 2 connects the battery 21 to the step-down circuit 22, and then connects the capacitor 23 to reduce the battery voltage to the working voltage to the pen capacitor head 1, so that the pen capacitor head 1 can work to change the charge of the touch device. Triggered by distribution.

However, the detailed description of the present invention is intended to be illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention. The patent scope of this case.
