Multi-point touch device and control method

Abstract

The invention relates to the field of multi-point touch screens, in particular to a multi-point touch device and a control method. A multi-point touch device comprises a supporting body, a first insulating layer covering a handheld part of the supporting body, and a plurality of conductive points arranged on the contact surface of the supporting body, wherein a conductive layer is arranged betweenthe first insulating layer and the supporting main body, and the conductive points are connected with the conductive layer. According to the multi-point touch device, multi-point touch is conducted on the capacitive touch equipment through the multi-point touch device, a human body does not need to make direct contact with the electric conductor, meanwhile, the electric conductor is wrapped and does not make contact with the outside such as the human body or the capacitive touch equipment, and the safety and durability of the multi-point touch device are improved; and the problem that the sanitation and safety of a user are affected due to falling of carbon powder from conductive silica gel is solved.

Description

technical field [0001] The invention relates to the field of multi-point touch screens, in particular to a multi-point touch device and a control method. Background technique [0002] Multi-touch technology is also called multi-touch technology. Different from the traditional single-point touch screen, the biggest feature of the multi-point touch screen is that two hands, multiple fingers or even multiple people can operate the content of the screen at the same time, which is more humane. [0003] For example, capacitive touch screen technology is used to realize multi-touch technology. Touch screen technology is a new type of human-computer interaction input method. Compared with traditional keyboard and mouse input methods, touch screen input is more intuitive. With recognition software, the touch screen can also realize handwriting input. [0004] Especially in application software that can obtain corresponding instructions according to the multi-point position of multi...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a multi-touch device and a control method for the above-mentioned defects of the prior art, so as to solve the problem that the existing multi-touch device requires the human body to directly contact the conductor, resulting in limited material appearance, The conductive contacts protrude from the bottom plane of the hardware, which affects the safety, durability and design limitations of the hardware; it also solves the problem that the conductive silicone will be directly exposed, such as contact with the human body, or contact with touch screen equipment, which often leads to conductive silicone. Falling toner will affect the health and safety of users
