Fig. 1 is a flow chart of an electrostatic protection method of a liquid crystal panel according to an embodiment of the disclosure. The static electricity protection method of the liquid crystal panel in the embodiment can be executed by the static electricity protection device of the liquid crystal panel, or can be executed by electronic equipment, and when the static electricity protection method is executed by the electronic equipment, the static electricity protection device is executed by a main control chip in the electronic equipment, wherein the electronic equipment can be a mobile phone, a tablet personal computer, a notebook computer, a wearable device and other devices with the liquid crystal panel. The following embodiments explain the present application by taking as an example the electrostatic protection method of the liquid crystal panel of the present embodiment performed by the electrostatic protection device of the liquid crystal panel of the present embodiment, but are not limiting to the present application.
As shown in fig. 1, the electrostatic protection method of the liquid crystal panel may include the steps of:
step 101, reading a register address from a preset monitoring list, and reading a register value corresponding to the register address.
The preset monitoring list may be preset, and the addresses of the registers with readable attributes are stored in the monitoring list, that is, the registers corresponding to the addresses of the registers stored in the monitoring list are readable registers.
The liquid crystal panel is correspondingly provided with a plurality of registers, each register has a unique register address, and in this embodiment, after the initialization of the liquid crystal panel is completed, the addresses of the registers which are configured in the initialization process and have readable attributes can be saved to obtain a monitoring list, and the monitoring list is stored.
In this embodiment, the electrostatic protection device of the liquid crystal panel may periodically read the register address from the monitor list, and obtain the register value corresponding to the register address according to the read register address.
Because the registers of the liquid crystal panel are many, the register addresses stored in the monitoring list are also corresponding to many, and if all the register addresses are read from the monitoring list each time and then the register values corresponding to the register addresses are obtained, more liquid crystal panel resources are occupied. Therefore, in one possible implementation manner of the embodiment of the application, several register addresses can be read each time, and only the register values corresponding to the register addresses are obtained, so that the resource occupation of the liquid crystal panel is reduced.
Specifically, reading the register address from the preset monitoring list may include:
and reading N register addresses from the monitoring list according to a preset time interval, wherein N is a positive integer, and N is smaller than the total number of the register addresses stored in the monitoring list.
Further, to ensure that all register addresses in the monitor list are traversed over a period of time, in one possible implementation of the embodiments of the present application, different register addresses may be read each time a register address in the monitor list is read. For example, N register addresses may be sequentially read according to the arrangement order of the register addresses in the monitor list, for example, when the register addresses in the monitor list are arranged in the order from top to bottom, N register addresses may be read each time according to the order from top to bottom, N register addresses before the first reading, N register addresses after the reading after the preset time interval, and so on, until the liquid crystal panel is reset, and then the register addresses are sequentially read again.
In this embodiment, after the register address is read, the register value corresponding to the register address can be obtained.
Daemon threads are a special kind of process running in the background, independent of the control terminal and periodically performing certain tasks or waiting to process certain occurring events. Thus, in this embodiment, as a possible implementation manner, a daemon thread may be preset, and the electrostatic protection device of the liquid crystal panel may start the daemon thread, read the register address from the monitor list through the daemon thread, and access the register of the liquid crystal panel through the read command, to obtain the register value corresponding to the read register address.
Step 102, according to the register address, obtaining a register initial value corresponding to the register address from a preset register initialization list.
In this embodiment, after the register address is read from the monitor list, the initial value of the register corresponding to the register address may be obtained from the preset register initialization list according to the read register address. The register initialization list stores a mapping relationship between each register address and a corresponding register initial value, where the register initial value is used for initializing the liquid crystal panel, that is, after initializing the liquid crystal panel, the value of the register is configured as the corresponding register initial value.
Step 103, comparing whether the initial value of the register is consistent with the value of the register.
In this embodiment, after the register initial value and the register value corresponding to each register address are obtained, the register initial value and the register value of each register address may be compared, whether the register initial value and the register value are consistent is determined, and if the register initial value and the register value are consistent, the flow is ended; if not, step 104 is performed.
Step 104, if it is known that the register initial value corresponding to the register address is inconsistent with the register value, resetting the liquid crystal panel.
In this embodiment, for each read register address, the register initial value and the register value corresponding to the read register address are compared, and if the register value corresponding to any register address is inconsistent with the register initial value, the liquid crystal panel is considered to be affected by static electricity, so that the liquid crystal panel is reset, and the purpose of static electricity protection is achieved.
It can be understood that the control chip is arranged on the liquid crystal panel, when the control chip of the liquid crystal panel is affected by static electricity, the control chip senses work failure, and the value of the register of the liquid crystal panel is changed, so that the value of the register is not the initial value of the register. Therefore, in this embodiment, by acquiring the register value and comparing the register value with the corresponding initial value, it can be determined whether the liquid crystal panel is affected by static electricity, and reset when the liquid crystal panel is affected by static electricity.
In one possible implementation manner of the embodiment of the present application, when the liquid crystal panel is reset, a reset instruction may be sent to a reset pin of the liquid crystal panel, so that the reset pin sends a reset pulse according to the reset instruction to reset the liquid crystal panel.
Typically, the reset pulse is low for a period of time. In this embodiment, when the reset is required, the electrostatic protection device of the liquid crystal panel controls the reset pin of the liquid crystal panel to send a reset pulse by sending a reset instruction, and starts the hardware reset of the liquid crystal panel, so as to improve the electrostatic protection performance of the liquid crystal panel.
In one possible implementation manner of the embodiment of the present application, after the electrostatic protection device of the liquid crystal panel reads the register address from the monitoring list, if the register corresponding to any one of the register addresses fails to be read, the liquid crystal panel is reset.
According to the static electricity protection method of the liquid crystal panel, the register address is read from the preset monitoring list, the register value corresponding to the register address is read, the register initial value corresponding to the register address is obtained from the preset register initialization list according to the register address, whether the register initial value is consistent with the register value is further compared, and when the fact that the register initial value corresponding to the register address is inconsistent with the register value is obtained, the liquid crystal panel is reset. Therefore, the purpose of static electricity protection is achieved by controlling the reset of the liquid crystal panel, the static electricity protection is achieved in a software mode, the hardware design is not required to be changed, and the static electricity protection performance of the liquid crystal panel is improved.
In order not to influence the normal use of the user, the user experience is improved, and the working state of the liquid crystal panel before the reset can be restored. Therefore, another method for protecting an electrostatic discharge protection device of a liquid crystal panel is provided in the embodiment of the present application, and fig. 2 is a schematic flow chart of the method for protecting an electrostatic discharge protection device of a liquid crystal panel according to another embodiment of the present application.
As shown in fig. 2, the electrostatic protection method of the liquid crystal panel may include the following steps:
step 201, reading a register address from a preset monitoring list, and reading a register value corresponding to the register address.
Step 202, according to the register address, obtaining a register initial value corresponding to the register address from a preset register initialization list.
In step 203, the register initial value and the register value are compared to determine whether they are consistent.
In this embodiment, the descriptions of the steps 201 to 203 may be referred to the descriptions of the steps 101 to 103 in the foregoing embodiments, and are not repeated here.
Step 204, if it is known that the register initial value corresponding to the register address is inconsistent with the register value, the current working state of the liquid crystal panel is recorded.
In this embodiment, for each read register address, the corresponding register initial value and the register value are compared, if the register value corresponding to any register address is not consistent with the register initial value, the liquid crystal panel is considered to need to be reset to realize electrostatic protection, so as to ensure that the use of the user is not affected before and after the reset, and the current working state of the liquid crystal panel can be recorded before the reset.
It can be understood that the different liquid crystal panels provide different functions, and thus different operating states. For example, for a touch screen, its operating state includes, but is not limited to, firmware upgrade state, factory mode, touch coordinate processing, etc.; for a liquid crystal display, its operating state includes image output.
In this embodiment, when the register value corresponding to a certain register address is not consistent with the register initial value, the current working state of the liquid crystal panel is recorded, for example, when the current touch screen is performing touch coordinate processing, the corresponding touch coordinate is recorded, and the touch coordinate processing is suspended.
Step 205, resetting the liquid crystal panel.
And 206, controlling the liquid crystal panel to work according to the working state.
In this embodiment, after the liquid crystal panel is reset, the liquid crystal panel is initialized again, the register value of the liquid crystal panel is reconfigured to be the corresponding register initial value, the working environment is restored according to the working state of the liquid crystal panel recorded before the reset, and the liquid crystal panel is controlled to work according to the recorded working state. For example, restarting the factory mode of the touch screen, restarting the reporting of touch coordinates, starting the image output of the liquid crystal display, etc.
According to the static electricity protection method of the liquid crystal panel, the register address is read from the preset monitoring list, the register value corresponding to the register address is read, the register initial value corresponding to the register address is obtained from the preset register initialization list according to the register address, whether the register initial value is consistent with the register value is further compared, when the fact that the register initial value corresponding to the register address is inconsistent with the register value is obtained, the current working state of the liquid crystal panel is recorded, and after the liquid crystal panel is reset, the liquid crystal panel is controlled to work according to the working state. Therefore, the purpose of static protection is achieved by controlling the reset of the liquid crystal panel, static protection is achieved through a software mode, hardware design is not required to be changed, the static protection performance of the liquid crystal panel is improved, the working state of the liquid crystal panel before reset is recorded, the working state is recovered after reset, normal use of a user is guaranteed, and user experience is improved.

As shown in fig. 3, the electrostatic protection method of the liquid crystal panel may include the steps of:
step 301, reading a register address from a preset monitoring list.
In step 302, a register corresponding to the register address is accessed through a read command to obtain a register value.
Step 303, determining whether a register value is obtained.
In this embodiment, when the register corresponding to the register address is read, the reading may fail, or the reading may succeed, and when the register corresponding to each register address is read, the reading is judged to succeed, and step 304 is executed; when the register value corresponding to the at least one register address is not read, it is determined that the reading fails, and step 306 is performed.

For example, the reading of the register address may be started when a preset time interval is reached.
