Embodiment 1

[0075] This embodiment provides a device capable of reducing the probability of occurrence of false alarm point events on the touch screen, and the device is provided with a full-screen fingerprint device. The full-screen fingerprint device is usually superimposed with the touch screen, or directly constitutes a part of the touch screen, and can obtain the user's fingerprint information when the user clicks on the touch screen. When the user touches the touch screen of the device, the device can obtain the position of the touch point, and use the full-screen fingerprint device on the device to collect the touch parameters of the touch subject. When the collected touch parameters meet certain conditions, the touch point is a valid touch point. Using this solution can effectively judge whether the position of the touch point is correct before the device reports the touch point to the system. Using the full-screen fingerprint device on the device to collect touch parameters can i...

Embodiment 2

[0098] see Image 6 , this embodiment shows a device for reducing touch screen false positives, including: a controller 61 and a user input unit 62 , wherein the user input unit 62 includes a touch screen module 621 and a full-screen fingerprint module 622 . The touch screen module 621 can be implemented by an existing touch screen, and the full-screen fingerprint module 622 can be superimposed on the touch screen to identify the skin texture of the user touching the touch screen. Wherein, the touch screen module 621 and the full-screen fingerprint module 622 of the user input unit 62 are connected to the controller 61 , and can access the data collected by itself to the controller 61 .

[0099] Wherein, the touch screen module 621 is used to obtain the touch point position of the touch main body on the touch screen when touching the touch screen of the main body touch device;

[0100] The full-screen fingerprint module 622 is used to collect touch parameters of the touch sub...

Embodiment 3

[0119] See eg Figure 7 , this embodiment shows a method for reducing touch screen false alarm points, including

[0120] S701. When touching the touch screen of the main body touch device, acquire the touch point position of the touch main body on the touch screen;

[0121] S702. Use the full-screen fingerprint device to collect touch parameters of the touch subject; the touch parameters include the skin texture of the touch subject within a preset position range;

[0122] S703. If the relationship between the touch parameter and the position of the touch point satisfies the preset touch condition, determine that the position of the touch point is valid.

[0123] In this embodiment, the device for reducing touch screen false alarm points can be any device equipped with a touch screen and a full-screen fingerprint device. Further, the device can be an existing terminal, including a fixed terminal, such as a touch screen Smart TV; the terminal can also be a mobile terminal, s...

Abstract

The invention discloses a device and method for reducing false alarm points of a touch screen. When the touch screen of the touch device of the main body is touched, the position of the touch point of the touch main body on the touch screen is acquired; Collection; the touch parameters include the skin texture of the touching subject and the collection position of the skin texture; if the relationship between the collection position and the touch point position and the skin texture meet the preset touch conditions, it is determined that the touch point position is valid. With the solution proposed by the present invention, when a user touches a device such as a mobile phone, the full-screen fingerprint device is used to verify whether the screen reporting point is the user's real touch point, thereby reducing false positive points on the touch screen. When there is no need to choose a higher-cost touch screen, the goal of improving the accuracy of touch reporting is achieved.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a device and method for reducing touch screen false alarm points. Background technique [0002] At present, with the use of mobile terminals such as mobile phones and computers, users rely more and more on terminals to complete affairs such as basic necessities of life. Users spend more and more time using terminals. [0003] Generally, during the operation of the terminal, when the user clicks on the touch screen, the touch screen will collect the touch point clicked by the user, and then report the touch point to the system of the terminal. However, during this process, sometimes the touch screen falsely reports a point. For example, the user wants to click point A on the screen, but the touch point reported by the touch screen is not point A. This false positive point will bring the user very bad experience, making the terminal product have a poor experience in the user's ...
