Unless the context clearly dictates otherwise, expressions used in the singular form encompass expressions in the plural form. In the present specification, it will be understood that terms such as "including," "having," and "containing" are intended to specify the presence of the features, integers, steps, acts, or combinations thereof disclosed in the specification, and are not intended to preclude the presence or addition of one or more other features, integers, steps, acts, or combinations thereof.

As shown in fig. 1, the present application provides a flow chart of steps of a method for detecting a touch screen of a mobile terminal, including:
step S110: and acquiring a corresponding detection character string of the touch screen.
In this step, the detection character string is used to identify whether the touch screen matches the mobile terminal, and the detection character string includes a plurality of detection characters. The detection character string further comprises a start character and an end character, wherein the start character and the end character are arranged at two ends of the detection characters and are used for detecting a transitional state when the touch screen is not lightened or the detection is not started.
Step S120: when the touch screen is lightened, the pin voltage of the touch screen is obtained.
Step S130: whether the pin voltage is within a voltage range of a first level is judged according to the pin voltage.
In this step, the first level includes a high level and a low level. In order to automatically identify the switching between high and low levels of the mobile terminal, the detection of a first character is avoided when a pin of a touch screen of the mobile terminal is switched between the high and low levels. The difference between the upper and lower thresholds of the high level of the pin is typically set to 20% of the high level of the touch screen pin voltage.
Step S140: detecting whether the pin voltage is within a voltage range of a second level.
In this step, when the pin voltage is within the voltage range of the first level, it is further detected whether the pin voltage is within the voltage range of the second level.
Step S141: ceasing the detection of whether the pin voltage is within a voltage range of a second level.
In this step, when the pin voltage is determined to be outside the voltage range of the first level, the detection of whether the pin voltage is within the voltage range of the second level is stopped.
Step S150: the first character is output.
In this step, when the pin voltage is within the voltage range of the second level, the first character is output. Typically, 10% of the difference between the upper and lower thresholds of the high level is selected to be the voltage range of the second level, for example, if the high level voltage of the pin is 5 v, then the difference between the upper and lower thresholds of the high level is selected to be 0.5 v.
Step S151: and outputting the second character.
In this step, a second character is output when the pin voltage is outside the voltage range of the second level.
Step S152: and when the second character is output, determining that the touch screen is not matched with the mobile terminal.
Step S160: and when the output first character is the same as the detection character of the detection character string, the touch screen is matched with the mobile terminal.
In this step, when there are a plurality of pin voltages, a plurality of first characters are output in step S150, and when the plurality of first characters are the same as the plurality of detection characters of the detection character string, it indicates that the touch screen is matched with the mobile terminal. Of course, in some embodiments, when there is only one pin voltage, only one first character is output in step S150, and when the one first character is the same as a single detection character of the detection character string, it indicates that the touch screen is matched with the mobile terminal.
According to the detection method of the mobile terminal touch screen, whether the pin voltage is located in the voltage range of the first level or not is judged firstly according to the pin voltage, and 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, so that the influence of voltage instability on a detection result during high-low level switching can be avoided. When the pin voltage is in the voltage range of the second level, the first character is output, and when the output first character is the same as the detection character in the detection character string, the touch screen is matched with the mobile terminal, so that the mobile terminal can automatically and dynamically identify the connected touch screen, and further the problems of abnormal functions, even burning out and the like caused by the fact that a user installs the touch screen which is not produced by a mobile terminal manufacturer are avoided.
