Method for inputting information by keys and electronic device with keys

Abstract

The embodiment of the invention discloses a method for inputting information by keys and an electronic device with keys, which relate to the technical field of electron and solve the technical problem that in the prior art, the accuracy of information input by keys is poor. The method of the invention comprises the following steps: pressing down a key or a touch-key; when the key is pressed down or touched, sending a pressing signal corresponding to the pressed or touched key; when the key is uplifted or released, sending an uplifting signal corresponding to the uplifted or released key; and receiving the pressing signal and the uplifting signal, and when the time interval between the pressing signal and the uplifting signal corresponding to the same key is less than a preset effective time interval, according to a character corresponding to the key, completing the operation corresponding to the character. The electronic device with keys comprises keys, a touch module and a master control module. The invention is applied to the improvement of accuracy of information input by keys.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method for inputting information by using keys and an electronic device provided with keys applying the method for inputting information by using keys. Background technique [0002] With the continuous development of electronic technology, various electronic devices provided with keys, such as flat panel display devices with full capacitive touch keyboards, are more and more widely used. [0003] Existing electronic devices provided with buttons include a plurality of buttons, a touch chip, a main control chip, and a display screen. The sensing chip corresponding to the button is connected to the touch chip, and the touch chip is connected to the main control chip, wherein: [0004] The touch chip is used to send a pressing signal corresponding to the pressed or touched key when the key is pressed or touched; [0005] The main control chip is used to receive the pr...

AI Technical Summary

Problems solved by technology

[0009] In the prior art, when a key is pressed or touched, the touch chip will generate a pressing signal, and after receiving the pressing signal, the main control chip will directly control the display screen to display the characters on the key corresponding to the pressing signal. The character corresponding to the pressed or touched key. In the process of actually using the key, when the user presses or touches the key with his finger, it is often easy to unintentionally press or touch some irrelevant keys, resulting in the process of using the key. Misoperation is prone to occur in the computer, and the probability of such misoperation is higher when using a full capacitive touch keyboard that can be triggered with just one touch, resulting in poor accuracy of key input information
