The invention discloses a detection method and device for a touch screen of a mobile terminal, a storage medium and the mobile terminal. According to the detection method for the touch screen of the mobile terminal, whether the pin voltage is located in the voltage range of the first level or not is judged according to the pin voltage; when the pin voltage is located in the voltage range of the first level, whether the pin voltage is located in the voltage range of the second level or not is further detected; therefore, the influence of unstable voltage on the detection result during high-lowlevel switching can be prevented. When the pin voltage is within the voltage range of the second level, a first character is output; when the output first character is the same as a detection character in a detection character string, the touch screen is matched with the mobile terminal, and therefore the mobile terminal can automatically perform dynamic identification on the connected touch screen; furthermore, the problems of abnormal functions, even burnout and the like caused by the fact that a user installs a touch screen produced by a non-mobile terminal manufacturer are prevented.
Description
technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a detection method, device, storage medium and mobile terminal for a touch screen of a mobile terminal. Background technique [0002] At present, all mobile terminals use the entire touch screen, so that users can have more operating space on the smaller mobile terminal. If it is damaged by falling, water ingress, etc., the replaced touch screen at this time may not be produced by the mobile terminal manufacturer, and the corresponding parameters do not match, causing some problems in the user's use process. [0003] Therefore, there is an urgent need for a new detection method to solve the problems in the prior art. Contents of the invention [0004] The embodiment of the present application provides a detection method, device, storage medium and mobile terminal for a touch screen of a mobile terminal, which are used to solve the problem of unstable de...
