A tactile system for touch screen detection and adjustment

Abstract

The invention provides a tactile system for detecting and adjusting a touch screen. The tactile system includes a detection device, a moving device, a limit device, a transportation device, an adjustment device, a trigger device and a processor. The detection device is configured to detect the touch screen, move The device is configured to convert the position of the detection device; the limit device is configured to limit the touch screen on the transport device, and the adjustment device is configured to collect parameters of the touch screen and adjust the touch screen; the trigger device is configured to Simulates a touch on the touch screen. The present invention determines the touch coordinates of the passive touch object close to the sensing array by indicating the capacitive coupling of the trigger signal to multiple electrodes through the passive touch object, ensuring the accuracy of touch screen detection, and at the same time, determining the position of the detected coordinates Adjust the sensitivity to ensure that the touch screen can reliably detect and correct the touch during the detection process.

Description

technical field [0001] The invention relates to the technical field of touch screen production, in particular to a tactile system for touch screen detection and adjustment. Background technique [0002] Touch screens have been widely used in electronic products; touch screens provide a simple, light and inexpensive pointing device. Generally speaking, the capacitive touch screen has a planar structure. If it is applied to keyboard input, when the user touches the planar structure with his finger, he lacks the finger touch of pressing the button. [0003] For example, CN103135810B prior art discloses a method and system for adjusting the pressure sensitivity of a touch screen. The pressure sensitivity of the touch screen is a working parameter that reflects whether the touch screen is touched by a contact point. The mobile terminal has fixed the pressure sensitivity of the touch screen when it leaves the factory, and the user cannot modify it. For example, for the same mobil...

[0003] For example, CN103135810B prior art discloses a method and system for adjusting the pressure sensitivity of a touch screen. The pressure sensitivity of the touch screen is a working parameter that reflects whether the touch screen is touched by a contact point. The mobile terminal has fixed the pressure sensitivity of the touch screen when it leaves the factory, and the user cannot modify it. ; For example, the pressure sensitivity of the touch screen is the same for the same mobile phone regardless of whether the user is male, female, old or young, thus greatly reducing the user experience effect

Another typical prior art such as WO2015035546A9 discloses a touch display screen and electronic equipment, and a prior art such as WO2017045362A1 discloses a touch screen and its touch detection method. Capacitive touch screens have the disadvantage of being susceptible to environmental interference , it is difficult to accurately capture the touch behavior that occurs when wearing gloves and fingers with water for touch or when using outdoors in rainy, snowy and other weather

At the same time, the capacitive touch screen has the problem of touch misoperation when the finger is suspended above the touch screen due to its high sensitivity.

In addition, the capacitive touch screen only senses the touch position on the plane where the screen body is located, and it is difficult to support the sensing of touch parameters perpendicular to the plane of the screen body

[0004] In order to solve the common problems in the field that the sensitivity of the touch screen cannot be adjusted, the tactile experience is poor, the change of pressing cannot be detected, and the lack of adjustment can easily cause false touches, etc., the present invention is made
