With the rapid development of smart phones and tablet computers, touch screens are widely applied in daily life. At present, a mobile terminal (such as a mobile phone and a tablet device) generally has a handwriting function, for example, a tablet device for students to learn, the tablet device can complete a series of functions related to drawing, such as calligraphy practicing, dictation, drawing, and the like, through a handwriting pen, but due to the characteristics that a user group has special physical characteristics (a student has a small body size) and the tablet device is larger than a mobile phone screen, in the writing process, the situation that other parts (such as fingers, palms, and the like) touch the screen cannot be avoided except the handwriting pen, so that the situations that the writing process is not smooth, the false triggering is easy, and the writing result is not ideal exist.
For the above situation, at present, the problem of false triggering of the mobile terminal is mainly avoided through an interactive design, for example, modes such as reducing a writing area and giving a prompt on a screen are adopted, but these modes cannot completely avoid the problem of false triggering, such as:
1. in the writing process, the hand holding the pen can touch the writing area by mistake;
2. if the program is a drawing program, the drawing area is limited to be unreasonable;
3. the user does not necessarily have to be aware of the prompt given on the screen and there is still a possibility of false triggering.
In summary, the conventional method is difficult to effectively reduce the probability of false triggering of the mobile terminal in writing. When people use the stylus pen on the touch screen, poor writing experience is easily caused because fingers or wrists touch the screen to be out of order.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
As shown in fig. 1, the present invention provides a method for preventing a touch screen from being touched by mistake, which includes:
step S1, arranging a plurality of touch points 101 in the touch screen 100, wherein the touch points 101 are distributed in an array manner, and the area of each touch point 101 is smaller than a set value;
and step S2, acquiring touch information on each touch point 101 in each unit time, where the touch information is used to indicate whether the touch point 101 is clicked, the touch screen 100 displays a mark on the individually clicked touch point 101, and the touch screen 100 does not display a mark on at least two adjacent touch points 101 that are clicked at the same time.
Specifically, the touch screen 100 may be a touch screen 100 of any terminal, and the touch screen 100 may start a handwriting function. As shown in fig. 2, step S1 is executed, when the touch screen 100 enters the handwriting mode, a plurality of touch points 101 are disposed in the touch screen 100, and the plurality of touch points 101 are distributed in an array to form an array of touch points 101 arranged in rows and columns like pixels. The contacts 101 are overlaid on the touch screen 100 next to each other, and the spacing (within an error tolerance) between every two adjacent contacts 101 in the row direction and the column direction is 0.
Further, the color of the touch point 101 may be lighter, such as white or gray, and the touch point 101 may be hidden (or nearly hidden) in the touch screen 100, so that the touch screen 100 is more beautiful in the handwriting mode.
In this embodiment, the area of each contact 101 is smaller than a predetermined value. When the screen 100 is touched by a finger, the area of the contact surface must be larger than 4 square millimeters to manipulate the screen. In this embodiment, the set value is less than or equal to 4 square millimeters (the contact 101 is square, and the side length of the contact 101 is less than or equal to 2 millimeters), so that when a finger or an elbow touches the touch screen 100, a single contact 101 cannot be clicked, and at least two or more contacts 101 are clicked, specifically, as shown in fig. 3, a black contact 101 in fig. 3 represents a simultaneously clicked contact 101.
Further, the touch screen 100 is clicked with a stylus pen. The touch screen 100 in this embodiment is a capacitive screen, such as a capacitive pen. The existing capacitance pens can be divided into two types, one type is called a passive capacitance pen, and the other type is called an active capacitance pen. The principle of the passive capacitance pen is that the pen point is made of a conductive material, and the passive capacitance pen has the same touch effect as a finger, and has the defect that the pen point cannot be made to be too thin, otherwise, the screen is delayed or fails when the touch is clicked, and therefore, the problem of mistaken touch is easily caused by a thick pen point. In this embodiment, an active capacitance pen is used as a stylus pen to click the contact 101, an area of a pen tip of the active capacitance pen may be smaller than or equal to 1 square millimeter, when the active capacitance pen clicks the touch screen 100, only one contact 101 may be clicked alone, specifically, as shown in fig. 4, a black contact 101 in fig. 4 represents the independently clicked contact 101. And moreover, a sensor is arranged in the refill of the active capacitance pen, so that the click precision of the active capacitance pen is higher.
Next, step S2 is executed to acquire touch information on each touch point 101 in each unit time, where the touch information is used to indicate whether the touch point 101 is clicked. The unit time is determined by the refresh frequency of the touch screen 100, and is, for example, 10 ms, 1 ms, or 10 ns.
After the touch information on each touch point 101 is obtained, it is known whether each touch point 101 is clicked. When the touch screen 100 is clicked by a stylus pen, only a single contact point 101 is clicked, and when a finger or a wrist touches the touch screen 100, two or more adjacent contact points 101 are clicked. In this embodiment, the touch screen 100 displays a mark on the touch point 101 that is clicked alone, and does not display a mark on at least two adjacent touch points 101 that are clicked simultaneously. That is, the touch screen 100 does not react to two or more adjacent touch points 101 that are clicked at the same time, thereby avoiding the problem of a false touch.
It should be understood that if a single touch point 101 and adjacent touch points 101 are clicked in the same unit time, the touch screen 100 will display a mark on the single clicked touch point 101, and the adjacent touch points 101 will not react to the touch screen 100, so that the normal operation will not be affected.
Further, as long as the touch information on each touch point 101 is acquired in each unit time, and then a mark is displayed on the touch point 101 clicked by the stylus pen, in the continuous unit time, the touch screen 100 generates a mark according to the track of the sliding of the pen tip of the stylus pen, and the continuous mark can display the handwritten information.
Based on the above method, as shown in fig. 5, the embodiment further provides a touch screen for preventing false touch, where the touch screen for preventing false touch may be a display screen used in any terminal, such as a liquid crystal display screen and an OLED display screen, and the touch screen includes:
the touch screen comprises a display module, a touch screen and a touch screen, wherein a plurality of contacts are arranged in the display module, the contacts are distributed in an array manner, the area of each contact is smaller than a set value, and the set value is smaller than or equal to 4 square millimeters;
the signal acquisition module is used for acquiring touch information on each contact in each unit time, and the touch information is used for indicating whether the contact is clicked or not;
the judging module is used for judging whether the contact is singly clicked or not according to the touch information; and
the control module is used for controlling the display module to display a mark on the independently clicked contact point when the contact point is independently clicked; when at least two adjacent touch points are clicked at the same time, controlling the display module not to display marks on the at least two adjacent touch points clicked at the same time.
The embodiment further provides a computing device, including:
one or more processors;
a memory for storing one or more programs;
when the one or more programs are executed by the one or more processors, the one or more processors are enabled to realize the touch screen false touch prevention method.
The computing device in this embodiment may be a PC, or may also be a terminal device with a touch screen display function, such as a smart phone, a tablet computer, an e-book reader, an MP4(Moving Picture Experts Group Audio Layer IV) player, a portable computer, and the like.
The computing device may include: a processor, e.g. a CPU, a network interface, a user interface, a memory, a communication bus. Wherein, the communication bus is used for realizing the connection communication between the components. The user interface may comprise a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface may also comprise a standard wired interface, a wireless interface. The network interface may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The memory may be a high-speed RAM memory or a non-volatile memory, such as a disk memory. The memory may alternatively be a memory separate from the aforementioned processor. Optionally, the computing device may further include a camera, RF (radio frequency) circuitry, audio circuitry, a WiFi module, and so on.
The processor may call a touch screen false touch prevention program stored in the memory to execute the touch screen false touch prevention method.
The embodiment also provides a computer readable storage medium, on which a computer program is stored, which when executed by a processor implements the touch screen false touch prevention method.
In summary, the invention provides a touch screen false touch prevention method, a touch screen, a computing device and a medium, wherein a plurality of contacts distributed in an array are arranged on the touch screen, the area of each contact is controlled to be smaller than a set value, one contact cannot be clicked independently due to too large finger area, only a sharp pen point can click one contact independently, touch information on each contact is obtained within each unit time, when one contact is single, the touch screen displays marks on the independently clicked contact, and when at least two adjacent contacts are clicked simultaneously, the touch screen does not react, so that false touch of fingers or wrists on the touch screen is prevented, and the problem of false touch response of the touch screen caused by touching the touch screen with fingers or wrists when a stylus pen is used for operating the touch screen is solved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
