Description

Stylus, mobile terminal and method for operating on mobile terminal by using stylus

The present invention relates to the field of communication technologies, and in particular, to a stylus, a mobile terminal, and a method for operating on a mobile terminal using a stylus. Background technique

In the field of handwriting input of mobile terminals, two schemes are currently the most common, one is a resistive screen input, and the other is a capacitive screen input.

The principle of the resistance screen input mode is: When the stylus is written on the touch screen, the contact portion of the screen is deformed due to the change of the contact pressure, thereby changing the resistance value of the point, and further detecting the writing position. Normally, the detection point is generally the four vertices of the screen, and the current handwritten position is calculated by the resistance change of the four vertices. The resistive screen input method is currently widely used on a large number of low-end touch screen mobile phones. The characteristic of the resistive screen is that it has no special requirements for the input device and is relatively inexpensive. However, it cannot support multi-touch recognition, and the screen is relatively soft and has limited effect under strong light.

The principle of capacitive screen input mode is as follows: The built-in device in the screen has high-frequency induced current. When a charged object approaches close enough to form a capacitance with the screen, the corresponding position will generate induced charge from the formed capacitor to the close. On the object, the position of the operation is judged by detecting the row in which the induced charge is located. Due to its principle, multi-touch control can be supported. Capacitive screens have certain requirements for input media. Generally, substances that must have a charge can be input. The common method is human finger input. At present, there are some background technologies that use a special stylus for input.

When people read, write, and input on a mobile terminal, it is often necessary to perform related operations on the content displayed on the mobile terminal, for example: page up or page scrolling of the picture or text displayed on the mobile terminal, or left Right-click to perform operations such as locking and unlocking. When using a touch screen mobile terminal, this requirement is usually achieved by sliding the stylus or finger. If you use the stylus to slide over the screen, the hand may be too heavy, which may damage the touch screen. The way the finger slides is not only inconvenient to operate, but also leaves a line of finger marks on the screen, and the user's experience is not high. If there is a stylus, it can make the user conveniently turn up and down and left and right when using the mouse wheel, which will be welcomed by many users. Summary of the invention

a power unit 101, configured to supply power to each stylus of the stylus;

The stylus used in the present invention is an active stylus, that is, it must have a certain internal driving operating current. The power supply unit 101 can be an internal power supply or an external power supply.

An operation input unit 102, configured to input operation information;

The function of the operation input unit 102 is: providing an interface for user input, providing the user with The user inputs the input structure of the operation information. For example, the operation input unit 102 can be a page turning operation button in four directions of up, down, left, and right, or other forms of buttons; or other forms such as a ball, a roller, an acceleration sensor, an infrared sensor input, and the like. The operation information is information that the user wants (the mobile terminal) to perform corresponding operations, for example, performing page turning operations in the up, down, left, and right directions, performing a lock screen, an unlocking operation, a left and right button operation, and the like.

a control circuit unit, configured to output an electromagnetic field signal corresponding to the operation information; in other words, the control circuit unit is configured to convert different operation information into different electromagnetic field signals, so that when the stylus outputs the electromagnetic field signal to the mobile terminal body Different electromagnetic field signals represent different operation information, and the mobile terminal body can obtain the operation information corresponding to the electromagnetic field signal by analyzing the induced electromagnetic field signal, thereby implementing related operations according to the operation information. purpose.
