Problems solved by technology

However, the working principle of the current mainstream capacitive pen includes the step of applying a driving voltage to the capacitive pen. Since the capacitive pen is driven by a higher voltage, it will inevitably generate a signal to the touch screen when it is close to the touch screen. Interference, and even cause the touch screen to falsely detect non-existing contact operations

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Reference attached figure 1 , the pressure-type capacitance pen includes two parts: a pen body 1 and a pen core 2. The pen body 1 is generally cylindrical. In a preferred embodiment, the pen body 1 is made of an insulating material (such as plastic) At least one end is open, and two conductor blocks 11 and 12 are arranged inside the pen body. The conductor blocks 11 and 12 are disc-shaped, connected with the plastic pen body around, and have holes in the middle; in addition, the conductor blocks 11 and 12 Two wires 13 and 14 are correspondingly connected respectively, and the wires 13 and 14 pass through the pen body 1 . A blocking element 24 can also be provided in the pen body, which is connected with the pen body 1 and cannot be separated or moved. The pen core 2 is placed inside the pen body 1 , and a part of the pen core 2 protrudes from the openin...

Abstract

A pressure capacitive pen comprises a pen body and a pen core placed in the pen body, two conductor blocks are arranged in the pen body, the pen core is provided with a contact element which is arranged between the two conductor blocks, and the pen core is partially exposed outside the pen body to form a pen point. The pressure capacitive pen is a capacitive touch pen. When the capacitive pen does not contact a touch device substantively, the capacitive pen almost has no affect on the capacitance of the touch device, but when the capacitive pen contacts the touch device, the capacitive pen can obviously change the capacitance of the touch device.

Description

technical field [0001] The invention relates to a capacitive pen for writing on a capacitive touch screen, in particular to a pressure-type capacitive pen that produces different use effects by sensing the pressure on the pen tip. Background technique [0002] Touch screen is one of the most common electronic applications in today's society. Mobile phones, tablet computers, game consoles, and notebook computers on the market today generally use touch screen devices. Recently, capacitive touch screens are widely loved by consumers. Screen is widely used. Capacitive touch screens are not only suitable for daily and entertainment applications, but also have penetrated into major application fields such as education, business, and medical care. . [0003] The increasing popularity of capacitive stylus provides more convenience for clicking and writing on the touch screen, and can achieve more delicate clicking operations, because the diameter of the tip of the capacitive stylu...
