Problems solved by technology
However, due to the limitation of the number of input terminals of the touch chip, the touch chip often cannot meet the application of some specific products. At present, there are two main ways to solve this problem: modify product requirements and increase the number of touch chips
Among them, the method of modifying product requirements is often unacceptable, and increasing the number of touch chips will increase product costs

Embodiment Construction
[0017] An embodiment of the present invention provides a method for implementing a touch key, connecting each input terminal of the touch chip to N touch keys, so that all the touch keys are connected to the input terminals of the touch chip, where N is greater than or equal to zero , and an integer less than or equal to the total number of touch keys on the touch screen, and then accurately determine the effectively triggered touch keys by detecting the signal strength of the effectively triggered touch chip input terminal and the touch keys and calculating the distance between the touch keys. The embodiment of the present invention also provides a corresponding touch control module.
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the p...

The invention discloses a realization method of touch keys and a touch control device. The realization method comprises the following steps of: connecting each input end of a touch control chip with the N touch keys, wherein N is larger than or equal to zero and is less than or equal to an integer of a total number of the touch keys on the touch screen; and accurately positioning the currently and effectively-triggered touch keys by utilizing the touch control chip through detecting the effectively-triggered input ends, detecting the intensities of output signals of the touch keys and calculating the distances among the touch keys. The realization method and the touch control device have the beneficial effects that the purpose of inputting of the more touch keys is realized under the condition of same input end resources, and the touch control chip is not required to be additionally arranged, so that the cost of products is effectively reduced; and meanwhile, the shaking-eliminating and deburring treatments are carried out on an output signal of the touch control chip, so that the reliability and the stability of the products are improved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing a touch button and a touch control device. Background technique [0002] With the development of communication technology, the touch screen has developed into the simplest and most direct way of human-computer interaction. Because it combines input devices and real devices without input devices such as mouse or keyboard, it has become more and more widely used. applied in various fields. However, due to the limitation of the number of input terminals of the touch chip, the touch chip often cannot meet the application of some specific products. At present, there are two main ways to solve this problem: modifying product requirements and increasing the number of touch chips. Among them, the method of modifying product requirements is often unacceptable, and increasing the number of touch chips will increase product costs. Contents of the invention ...
