and S1, when the acceleration Z-axis data of the terminal equipment is larger than or equal to a first preset value and the distance detection data is smaller than a second preset value, detecting whether the display screen of the terminal equipment is in a screen-off display state.

Specifically, in this embodiment, taking the mobile terminal as an example for explanation, when the mobile terminal is in the normal operation mode, the acceleration Z axis data Accz is monitored, when the mobile terminal detects that the acceleration Z axis data Accz is less than-9.6, the mobile terminal operating system starts to start the countdown, and when the countdown duration reaches 2s, the mobile terminal acquires the acceleration Z axis data Accz again. When the acceleration Z-axis data of the mobile terminal still meets Accz < -9.6, the mobile terminal starts to monitor the distance sensor data Ps, the mobile terminal detects that the distance sensor data Ps is less than or equal to 5cm, a mobile terminal operating system judges the current display screen display mode, the display screen display mode of the mobile terminal is a non-AOD mode, the mobile terminal acquires a display screen demura E7 register, the display screen demura E7 register of the mobile terminal is 0x40, and the mobile terminal resets the display screen.
It can be seen that, in this embodiment, the abnormal polling detection of the display screen is started in combination with the static state of the mobile terminal, which not only does not affect the user experience, but also solves the problem of screen blackness caused by ESD. Further, if abnormal display occurs under a specific condition, the display screen is powered off and powered on in sequence to enable the display screen to recover normal display. Therefore, system resources are saved, the performance of the display screen is guaranteed, the power consumption of the system is reduced, and the user experience is improved.
The method has the advantages that whether the display screen of the terminal equipment is in the screen-off display state or not is detected when the acceleration Z-axis data of the terminal equipment is larger than or equal to a first preset value and the distance detection data is smaller than a second preset value; if the display screen is not in the screen-off display state, and the acceleration Z-axis data is continuously detected to be smaller than the first preset value, or if the display screen is in the screen-off display state, whether a demura E7 register of the display screen is 0x40 is detected; if the demura E7 register is 0x40, resetting the display screen; and if the demura E7 register is not 0x40, continuing to execute the detection and judgment operation of the acceleration Z-axis data and the distance detection data. The efficient display screen black screen processing scheme is realized, so that the equipment performs polling detection in a static state, and performs reset operation according to a detection result, system processing resources are saved, display performance is guaranteed, and user experience is improved.
