Method and system for solving abnormal display of display screen

Abstract

The invention relates to a method and a system for solving abnormal display of a display screen. The display screen is a display screen of a handheld device, and the method is based on a detection and judgment circuit which comprises a main control module and a display screen connected with the main control module. The method includes that a general purpose input output (GIPO) port capable of being configured into an interruption port of the main control module is selected to be connected with a termination equipment (TE) signal end of the display screen; the main control module is initialized, and the GIPO port is configured into the interruption port; the TE signal end of the display screen outputs TE signals to be sent to the GIPO port of the main control module; the main control module counts pulse signals of the GIPO port; the main control module compares recorded data with a preset threshold value in preset time, wherein if the recorded data are smaller than the preset threshold value, the display screen is abnormal and a next step is performed; and the display screen is reset. According to the method and the system for solving abnormal display of the display screen, whether the display screen is rest is determined by judging the state of the current display screen, the operation is rapid, and the user experience is improved.

Description

technical field [0001] The invention relates to a display screen technology of a handheld device, and more specifically, relates to a method and system for solving abnormal display of a display screen. Background technique [0002] At present, the display screen will appear black screen abnormality due to static electricity or other interference. For example, mobile phones that are widely used now have a high probability of black screen when the mobile phone is affected by static electricity. At this time, it is necessary to unplug the battery and restart, or to switch the screen. can be restored afterwards. At present, the way to deal with the abnormal black screen of the display is basically to reduce the influence of static electricity as much as possible by improving the grounding of the display, and reduce the probability of a black screen. There is another way to process the display screen by reading the registers related to the display screen and judging whether the ...
