Embodiment Construction

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0028] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. According to the working principle and transmission information medium of the touch screen, it can be divided into many categories, including resistive touch screen, capacitive touch screen, infrared touch screen and surface acoustic wave touch screen, etc. Among them, capacitive touch screen is the most widely used touch scree...

Abstract

The embodiment of the invention discloses an anomaly detection method and device, a storage medium and terminal equipment. The method can comprise the steps that a touch signal acting on a touch screen is detected; judging whether a trigger event corresponding to the touch signal belongs to a first state or not based on the detected touch signal; wherein the first state represents that a touch point on the touch screen is in a pressed state; and if the trigger event belongs to a first state and the trigger event meets a preset exception strategy, determining that the touch signal is an exception signal, and triggering exception handling of the touch screen according to the exception signal.

Description

technical field [0001] The present application relates to the technical field of intelligent terminals, and in particular to an anomaly detection method, device, storage medium and terminal equipment. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. Among them, the capacitive touch screen is one of the most widely used types of touch screens in terminal equipment. It uses the capacitive sensing principle of the touch screen to work, and can judge whether objects such as fingers and stylus touch the touch screen, and the event status after touching the touch screen, such as Press (down) state, lift (up) state and moving state, etc. [0003] At present, under fluorescent lamps, water mist and other scenarios, the capacitive signal of the touch screen will be interfered by external signals such as current and water vapor, resulting in abnorma...
