Detailed ways

The gist of the present invention is to overcome the deficiencies of the prior art and provide a method for solving the problem of abnormal display on the display screen, especially when the product appearance and structure of the handheld device are determined. There is a huge advantage in showing the probability of an anomaly.

A handheld device with a display screen is snapped onto the surface of an object, ie the distance between the display screen and the surface of the object being touched is very small. At this time, if electrostatic contact discharge or air discharge is performed on the surface conductive interface of the whole machine, such as volume plus and minus keys, power button, camera button, USB interface, earphone jack, etc., there will be a certain probability that the display screen will display abnormally. the

The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

As shown in Figures 1 and 2, an implementation method for solving abnormal electrostatic display of a display screen, the display screen is a display screen of a handheld device, and the implementation method is based on a detection and judgment circuit, and the detection and judgment circuit includes a main chip and The electrostatic sensitive device and the LCD display screen are respectively connected with the main chip, and the steps of the realization method are as follows:

Step 1, setting the electrostatic sensitive device software of the handheld device to realize the threshold value for detecting the presence of static electricity;

Step 2. Detect whether there is static electricity, if yes, then perform step 3, otherwise, step 2 loop detection;

Step 3, the electrostatic sensitive device sends an interrupt signal to the main chip of the handheld device;

Step 4. The main chip detects whether there is any abnormality in the display register, if yes, execute step 5, otherwise return to step 2;
