Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] refer to Figure 1a , 1b , the present invention provides a touch recognition method based on a capacitive touch panel, which includes the following steps:

[0032] The system sets the key value of each single key and key combination, and sets the range of key value combinations allowed for a single function;

[0033] Define the key-value permission array of different types of keys, the purpose of which is to determine the tolerable range of each function during short press and long press according to the physical configuration and priority of the key. For example, some fingers are big. When pressing the middle button, one of the up, down, left, and right buttons may be triggered for a short time. The software can recognize it and intelligently ignore this short-term operation without increasing th...

Abstract

The invention discloses a touch recognition method based on a capacitive touch panel, which comprises the following steps: the system sets the key value of each single key and combination key, and sets the key value combination range permitted by a single function; the system records respectively The state of each button, set the rising edge flag and falling edge flag of each button; the system records the duration of the long button press, and sets the corresponding button long press flag; the system defines the ranking order of each button according to the above settings, and Generate short key value and long key value; the system receives the key command input by the user, and performs corresponding operations according to the allowable range of the key value. A touch recognition system based on a capacitive touch panel, which includes: a key value setting module, a key state setting module, a key determination module, and a key execution module. It not only ensures the recognition accuracy, but also does not increase the recognition time and does not affect the sensitivity. Widely used in the touch field.

Description

technical field [0001] The invention relates to the field of touch control, in particular to a touch recognition method and system based on a capacitive touch panel. Background technique [0002] Capacitive touch buttons are superior to traditional mechanical buttons in terms of beautiful appearance and service life. Therefore, the application fields of capacitive touch buttons are becoming more and more extensive, including home appliances, consumer electronics, industrial control and mobile devices. [0003] However, with the increase of touch function requirements, the size of the touch buttons is required to be smaller and more crowded, which brings problems such as difficult manipulation, slow button recognition, and high false recognition rate. The distance between each button is small, and many buttons have different functions of long and short pressing, and special functions of long and short pressing of two or three buttons. Using the commonly used anti-shake proce...
