Mistaken touch prevention method of touch panel

Abstract

The invention provides a mistaken touch prevention method of a touch panel. The mistaken touch prevention method specifically comprises the following steps: S1, monitoring and recording pressing states of a panel touch key and other panel control keys in real time; s2, when it is detected that one panel touch key is touched, waiting for a second preset time period after touch lifting; and S3, judging whether the touched panel touch key is mistakenly touched or not according to the touch states of the panel touch key and other panel control keys in the period from the first preset time period before the panel touch key is touched to the second preset time period after the panel touch key is touched and lifted. The invention provides a mistaken touch prevention method of a touch panel, whichcan effectively solve the problem of mistaken touch of the touch air conditioner panel, does not influence the normal use of a user, not only can reduce the driving interference to a driver or a passenger caused by mistaken touch of a touch screen, but also can improve the quality of the touch air conditioner panel.

Description

technical field [0001] The invention relates to the field of smart device interaction, in particular to a method for preventing false touches on a touch panel. Background technique [0002] With the development of electronic technology, touch panels have become a common input device for electronic equipment in people's lives, and touch panels for automotive air conditioners are gradually emerging. like figure 1 As shown, the main principle of the air conditioner touch panel is: the X channel of the Touch IC chip (not shown in the figure) sends the measurement pulse, and after passing through the coupling capacitance formed by the X and Y lines of the diaphragm, it returns to the chip through the Y channel. Internally, the Touch IC calculates the size of the coupling capacitance formed by the X and Y lines of the diaphragm by detecting the signal input from the Y channel. When the human hand touches the touch panel, the coupling capacitance of the diaphragm becomes smaller ...

Problems solved by technology

[0003] Compared with traditional physical buttons, touch buttons can improve the life of the buttons, and do not need to be pressed hard, and the operation is more convenient. However, it is easy for users to trigger the touch buttons unintentionally during practical use, such as when cleaning and wiping the dust on the touch panel.

In addition, the center console of a car has densely packed buttons. Generally, there are control keys for audio navigation, instrument panel, emergency alarm switch, air-conditioning outlet, and air-conditioning panel. Users may accidentally touch the air-conditioning panel when operating equipment other than the air-conditioning button

[0004] Unintentional triggering of air-conditioning buttons for different reasons will greatly reduce the user's driving experience, distract the user's driving attention, and cause driving safety problems
