Description

Technical Field

Background
A mobile terminal (e.g., a smart phone, a tablet computer, etc.) often encounters a display screen failure in an Electro-Static discharge (ESD) test. In the ESD test process, the display screen of the mobile terminal faces downwards (faces towards the desktop of the experiment table), so that the problems of screen blackness or screen splash and the like in the ESD test process are easily caused. The specific reason is that when the display screen of the mobile terminal faces downwards, the metal in the mobile terminal and the metal plate (generally an aluminum alloy plate) of the experiment table top form two electrodes of an electrostatic field, and the display screen of the mobile terminal is clamped in the middle, so that a driver IC (driver IC) of the display screen is interfered during an ESD test.
The ESD problem is mostly caused by insufficient anti-interference capability of the display module of the mobile terminal, and the modification period of the display module of the mobile terminal is long, and in the prior art, the display screen of the mobile terminal is mostly optimized through a software test optimization (for example, ESDcheck). The software testing optimization mechanism can regularly read the state of a driving chip of the display screen of the mobile terminal and optimize the display module in the abnormal state of the display module.
However, when the display module displays images at a high frame rate, if the software testing optimization mechanism regularly monitors and queries the state of the driver chip, system tasks are accumulated, and problems that the user experience is affected, such as display screen jamming, are caused.

Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a method for detecting electrostatic discharge according to an embodiment of the present invention, where the method is applied to a mobile terminal, where the mobile terminal includes at least one display screen, and as shown in fig. 3, the method includes:
step 301, judging whether a target display screen with a downward direction exists in at least one display screen of the mobile terminal.
In this step, the method determines whether a target display screen with a downward direction exists in at least one display screen of the mobile terminal, and if the target display screen with the downward direction exists in the at least one display screen of the mobile terminal, step 302 is executed; on the contrary, if there is no target display screen with a downward direction in at least one display screen of the mobile terminal, the process is ended.
The method for determining whether the target display screen with the downward direction exists in the at least one display screen of the mobile terminal may be determined by acceleration data detected by an acceleration sensor disposed in the mobile terminal, or by detecting an environment brightness value by a light sensor disposed on the mobile terminal, or by combining the acceleration data detected by the acceleration sensor disposed in the mobile terminal and the environment brightness value detected by the light sensor disposed on the mobile terminal, which is not specifically limited in this embodiment of the present invention.
The mobile terminalThe method can acquire acceleration data detected by the acceleration sensor and then judge whether the display screen of the mobile terminal faces downwards according to the acceleration data detected by the acceleration sensor. Specifically, the method may acquire a Z-axis acceleration value detected by the acceleration sensor, and then determine whether the Z-axis acceleration value is a preset acceleration value, and if the Z-axis acceleration value is the preset acceleration value, the method determines that the direction of the display screen of the mobile terminal is downward; conversely, if the Z-axis acceleration value is not the preset acceleration value, the method determines that the direction of the display screen of the mobile terminal does not face downwards. The preset acceleration value is the inverse of the gravity acceleration value, namely-9.8 m/s2
The method comprises the steps of obtaining an environment brightness value detected by the light sensor, and then judging whether the display screen of the mobile terminal faces downwards or not according to the environment brightness value detected by the light sensor. Specifically, the method obtains an environment brightness value detected by the light sensor, then judges whether the environment brightness value detected by the light sensor is smaller than a preset brightness value, and if the environment brightness value detected by the light sensor is smaller than the preset brightness value, the method determines that the direction of the display screen of the mobile terminal faces downwards; on the contrary, if the ambient brightness value detected by the light sensor is not less than the preset brightness value, the method determines that the direction of the display screen of the mobile terminal does not face downwards.
It is understood that, in some embodiments of the present invention, the method may also determine whether the display screen of the mobile terminal is oriented downward according to a combination of the two data. For example, the method may determine that the display screen of the mobile terminal faces downward when the Z-axis acceleration value detected by the acceleration sensor is the preset acceleration value and the environment brightness value detected by the light sensor is less than the preset brightness value.
The mobile terminal can also comprise two display screens, in this case, an acceleration sensor can be arranged in the mobile terminal, the method obtains acceleration data detected by the acceleration sensor, and then judges whether the direction of one of the two display screens of the mobile terminal is downward according to the acceleration data detected by the acceleration sensor. Specifically, the method may acquire a Z-axis acceleration value detected by an acceleration sensor of the mobile terminal, then determine whether the Z-axis acceleration value is a first preset acceleration value or a second preset acceleration value, and if the Z-axis acceleration value is the first preset acceleration value, determine that a first display screen of the mobile terminal is a target display screen with a downward direction; and if the Z-axis acceleration value is the second preset acceleration value, the method determines that the second display screen of the mobile terminal is a target display screen with a downward direction. For example, the first preset acceleration value may be 9.8m/s2Correspondingly, the second preset acceleration value may be-9.8 m/s2(ii) a The first preset acceleration value can also be-9.8 m/s2Correspondingly, the second preset acceleration value can be 9.8m/s2. The specific setting of the first preset acceleration value and the second preset acceleration value is related to the setting directions of the first display screen, the second display screen and the acceleration sensor, and the invention is not described in detail.
The method includes that light sensors can be respectively arranged on the front side and the rear side of the mobile terminal, for example, a first light sensor is arranged on one side of a first display screen, a second light sensor is arranged on one side of a second display screen, the method obtains environment brightness values respectively detected by the first light sensor and the second light sensor, then whether the obtained environment brightness values have environment brightness values smaller than a preset brightness value is judged, and if the environment brightness values detected by the first light sensor are smaller than the preset brightness value, the method determines that the first display screen of the mobile terminal is a target display screen with a downward direction; if the ambient brightness value detected by the second light sensor is smaller than the preset brightness value, the method determines that the second display screen of the mobile terminal is a target display screen with a downward direction. It can be understood that, for the case that the brightness detected by the first light sensor and the brightness detected by the second light sensor are both less than the preset brightness value, the method may further determine which display screen is in the on state to determine the target display screen, that is, determine the display screen in the on state as the target display screen.
It is understood that, in some embodiments of the present invention, the method may also determine the display screen of the mobile terminal facing downwards according to a combination of the two data. For example, the method may determine that the first display screen of the mobile terminal faces downward when the Z-axis acceleration value detected by the acceleration sensor is the first preset acceleration value and the environmental brightness value detected by the first light sensor is less than the preset brightness value. Correspondingly, the method may determine that the direction of the second display screen of the mobile terminal is downward when the Z-axis acceleration value detected by the acceleration sensor is the second preset acceleration value and the environmental brightness value detected by the second light sensor is less than the preset brightness value.
Step 302, judging whether the target display screen is in an open state.
In this step, if a target display screen with a downward direction exists in at least one display screen of the mobile terminal, the method judges whether the target display screen is in an open state; if the target display screen is in the open state, executing step 303; conversely, if the target display screen is in the closed state, the process ends.
And step 303, detecting whether the electrostatic discharge of the driving chip of the target display screen is abnormal.
In this step, if the target display screen is in an on state, the method detects whether electrostatic discharge of a driving chip of the target display screen is abnormal, and if the electrostatic discharge of the driving chip of the target display screen is abnormal, step 304 is executed; and conversely, if the static electricity of the driving chip of the target display screen is normally discharged, the process is ended.
The method for detecting whether the electrostatic discharge of the driving chip of the target display screen is abnormal may specifically be reading a status register of the driving chip of the target display screen, and then judging whether the driving chip is abnormal according to a value of the status register, or monitoring whether a frame synchronization signal of the driving chip of the target display screen is abnormal.
