Emergency processing method of broken touch screen of computer system and application of emergency processing method

Abstract

The invention relates to an emergency processing method of a broken touch screen of a computer system. The emergency processing method comprises the following steps of (1) detecting whether a touch screen is in failure or not by a touch control chip in real time; (2) sending an interrupt request to a computer main system by the touch control chip under the situation that the touch screen is in failure; (3) starting a touch screen failure emergency program by the computer main system after the interrupt request is received, wherein the touch screen failure emergency program can be at least used for setting the computer system into an external control mode and / or a key control mode. According to the emergency processing method disclosed by the invention, the touch screen can be detected in real time through the touch control chip, the touch screen failure emergency program can be started and can be at least used for setting the computer system into the external control mode under the situation that the touch screen is in failure, the touch screen can be at least subjected to emergency control by a user through the external control mode according to the emergency processing method when the touch screen breaks down, touch control operations such as input, data backup and data clear can be carried out, and the data loss can be avoided.

Description

Technical field [0001] The invention relates to a processing method for a touch screen, in particular to an emergency processing method for damage to a touch screen of a computer system and its application. Background technique [0002] Such as figure 1 As shown, at present, as a kind of intelligent terminal including a computer system, consumer electronic products such as mobile phones and tablet computers generally use touch screens for input. The computer system of this kind of intelligent terminal is generally as figure 1 As shown, it includes at least a central processing unit (CPU), which is respectively connected to a peripheral interface and a storage. The storage is generally loaded with a software system run by an intelligent terminal, which generally includes an operating system, various control modules, and application programs , And peripheral interfaces are generally connected with external ports (such as USB interfaces), wireless communication circuits, audio circui...

AI Technical Summary

Problems solved by technology

[0004] The touch screen is generally set in front of the display, so it is more prone to failure under the influence of external collisions, etc. In current consumer electronics products, since only this touch display system is used as an interactive device, when the touch screen fails, It will make the interactive function of the entire mobile phone completely invalid, making it impossible for the user to control the mobile phone at all. In particular, when the user stores important data on the consumer electronic product, the user can neither back up or clear the relevant data by himself, nor Rest assured that it will be handed over to others for maintenance, which often puts users in a desperate situation for information security
