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.

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0023] In this embodiment, the touch control method of a washing machine is described in detail by taking the touch control screen of a washing machine as an example.

[0024] like figure 1 As shown, in the touch method of the present invention, the touch panel mainly includes: a touch screen unit, a storage unit and a control unit, and the touch screen unit further includes an operation area for function or program selection and two detection units.

[0025] Among them, such as figure 2 As shown, the two detection units respectively include two detection points A and B to detect the vibration caused by the user touching the function or program selection operation area on the touch screen. The vibration points detected by the two detection units are transmitted to the two detection points A and B. Time value and / or time difference value of ea...

Abstract

The invention relates to a touch control method. Two detection units are arranged 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 to detect the vibration point transmitted to the two detection units. time value and / or time difference, and send the detected value to the control unit at the same time; after the control unit receives the value sent by the two detection units, it compares it with the standard value pre-stored in the storage unit to 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. The method fully realizes the touch mode of vibration detection, avoids the influence of electric field and other disturbances, has high detection accuracy, and is very convenient for users 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...
