A touch control method

Abstract

The invention relates to a touch control method. Two detection units are set in the touch screen unit to detect the vibration caused by the user touching the function or program selection operation area on the touch screen, and the vibration waves at the vibration points are respectively transmitted to the two detection units. The propagation time or propagation distance of each detection unit, and at the same time send the detected value to the control unit; after the control unit receives the value sent by the two detection units, it compares with the standard value pre-stored in the storage unit. By comparison, find the coordinate information corresponding to the vibration point, so as to determine the specific position of the user's operation point and the corresponding function or program, and respond accordingly to realize the function or program setting. This method fully realizes the touch mode of vibration detection, avoids the influence of interference such as electric field, has high detection accuracy, and is very convenient to use.

Description

technical field [0001] The invention relates to a touch control method and belongs to the technical field of touch screen control. Background technique [0002] At present, touch screens are generally used as display and operating devices in various fields such as household appliances. The touch screen is basically divided into a function selection touch area and a program selection touch area. The touch screen is connected to the control unit. The required function or program, and then complete all required operations. According to different touch control methods, currently generally used touch screens are basically divided into two types, one is a capacitive touch screen, and the other is a resistive touch screen. [0003] For a capacitive touch screen, when a finger touches the screen, due to the electric field of the human body, a coupling capacitor is formed between the user and the surface of the touch screen. For high-frequency current, the capacitor is a direct cond...

AI Technical Summary

Problems solved by technology

[0005] Whether it is a capacitive touch screen or a resistive touch screen, it is more susceptible to interference from electric fields, which in turn affects its use effect and detection accuracy

In addition, for the capacitive touch screen, since the human body becomes a part of the circuit, the drift phenomenon is more serious, and it will no longer work after wearing gloves, so the use is greatly restricted.
