Referring to fig. 2, fig. 2 is a flowchart of a method for locking and unlocking a display screen according to a first embodiment of the present invention.
In this embodiment, the method for locking and unlocking the display screen is suitable for a display terminal (hereinafter referred to as an OLED display terminal) equipped with an OLED (Organic Light-Emitting Diode) display screen, such as an OLED television, an OLED pad, and other Android large screens.
In order to avoid damage to the OLED display screen caused by hardware abnormity of the OLED display screen, the OLED display terminal is provided with a screen locking protection function of the OLED display screen during production. Based on the screen locking protection function of the OLED display screen, after the OLED display terminal is produced or leaves a factory, if the OLED display screen has abnormal conditions such as poor screen line plugging (such as plugging or incoming materials), poor T-CON (Timing Controller), poor glass or poor mainboard, the screen locking function of the OLED display screen can be automatically started, and the OLED display screen enters a screen locking state.
However, to unlock the OLED display screen in the screen-locked state, the screen can only be locked and unlocked by means of serial port printing through a terminal device such as a computer. The screen locking and unlocking mode is limited by terminal equipment such as a computer, so that the screen locking and unlocking operation of the OLED display screen is extremely inconvenient. Therefore, in order to improve the convenience of the screen locking and unlocking operation of the OLED display screen, the present embodiment provides a screen locking and unlocking method for a display screen, and the screen locking and unlocking of the OLED display screen can be completed without using a computer or other terminal devices. Specifically, the method for locking and unlocking the display screen comprises the following steps:
step S10: when the display screen is in a power-off state, receiving key operation corresponding to the display screen;
when the OLED display screen is in a shutdown state, the OLED display screen may be in a normal shutdown state (the display screen does not enter a screen locking state and the display screen is not damaged), or the OLED display screen may enter the screen locking state, or the OLED display screen may be damaged due to other reasons. At this time, if a key operation (a key operation corresponding to the OLED display) input by the user on the OLED display is received, the key operation may be a normal power-on key operation, or may be a target key operation corresponding to the screen-locking state, and the like, where the target key operation is particularly a key operation for triggering the OLED display to enter a pre-unlocking mode, and the pre-unlocking mode is particularly a preparation stage before entering the screen-locking unlocking mode. If the key operation is a startup key operation, a startup operation is executed in response to the startup key operation, and if the startup operation is executed, the OLED display screen still cannot be started, and the key operation corresponding to the screen locking state can be further triggered. Of course, the key operation corresponding to the screen locking state can also be directly triggered.
If the target key operation corresponding to the screen locking state is received, the screen locking and unlocking of the OLED display screen can be carried out after the target key operation is triggered, so that after the screen locking and unlocking of the OLED display screen are carried out, whether the OLED display screen is obviously abnormal or whether the OLED display screen enters the screen locking state again is further monitored, and whether the OLED display screen can be normally used after the screen locking and unlocking is further confirmed. If the OLED display screen is not abnormal and does not enter the screen locking state again after the screen locking and unlocking are carried out, the OLED display screen is shut down due to entering the screen locking state, and the OLED display screen can be continuously used after the hardware abnormity corresponding to the screen locking of the OLED display screen is checked; if the OLED display screen is abnormal or enters the screen locking state again after the screen locking is unlocked, the OLED display screen is possibly damaged, and the OLED display screen needs to be replaced or maintained.
The key operation input by the user on the OLED display screen may be a key operation triggered by directly operating a key on the OLED display screen, or a key operation triggered by operating a key on a control device of the OLED display screen. And the triggered key can be an independent function key or a combined key. For the single function key, the actual function of the function key can be distinguished from the screen locking and unlocking function through the key pressing times, the key pressing duration and the like based on the existing function key, for example, a menu key is pressed for a long time, or the menu key is continuously triggered twice within a preset time, and the like, namely, the screen locking and unlocking operation is triggered; or the function key for the screen locking state is specially developed on the OLED display screen or the control equipment (such as a remote controller) of the OLED display screen when the OLED display screen is produced. For the combined key, the functions can be distinguished by simultaneously triggering two or more keys on the OLED display screen, and simultaneously also by key-press times, key-press duration and the like, such as simultaneously triggering a power key and a menu key, or simultaneously triggering an add-subtract volume key within a preset time after the power key is pressed for a long time, namely triggering screen locking and unlocking operations. So, can trigger target button operation through the button on the controlgear of OLED display screen or OLED display screen for when OLED display screen is in the lock screen state, the user can independently trigger target button operation, so that in time unblock the OLED display screen, and need not to wait for fortune dimension personnel to go to the door operation, improved the convenience of OLED display screen lock screen unblock, and can guarantee the timely validity of OLED display screen lock screen unblock.
Step S20: if the key operation is a target key operation, responding to the target key operation, enabling the display screen to enter a pre-unlocking mode, and confirming the state information of the display screen when the display screen is in the pre-unlocking mode;
if the received key operation is the target key operation corresponding to the screen locking state, the OLED display screen can enter a pre-unlocking mode in response to the target key operation, namely, enter a preparation stage before the unlocking mode, so as to confirm whether the OLED display screen is in the screen locking state or not in the preparation stage. That is, when the OLED display screen is in the pre-unlocking mode, the state information of the OLED display screen can be acquired, and then whether the OLED display screen is in the screen-locking state or not is confirmed according to the state information, so that the OLED display screen enters the screen-locking unlocking mode when the OLED display screen is in the screen-locking state, and the screen-locking unlocking operation is performed on the OLED display screen.
When the OLED display screen cannot be started due to the abnormality, the system stores corresponding abnormal information into a preset system partition, and therefore after subsequent power-on, if the identification information of the OLED display screen lock screen is read from the preset system partition when a loading program is started in operation, the starting-up starting process is automatically terminated, and the OLED display screen enters a screen lock state.
Therefore, when the OLED display screen is in the pre-unlocking mode, the screen locking identification information can be obtained from the preset storage path, and whether the state information of the display screen is in the screen locking state or not is confirmed according to the screen locking identification information. That is, if the screen locking identification information is screen locking information of the OLED display screen and the screen locking information is a locked screen, it is determined that the state information of the OLED display screen is a screen locking state. If the screen locking identification information is not screen locking information of the OLED display screen or the screen locking information is not screen locking, the state information of the OLED display screen is determined to be a screen locking state, at the moment, hardware abnormity corresponding to the screen locking state of the OLED display screen can be eliminated, display screen faults caused by other reasons can be eliminated, and corresponding abnormity processing is carried out after the elimination.
Step S30: if the display screen is confirmed to be in the screen locking state according to the state information, controlling the display screen to enter a screen locking and unlocking mode, and executing screen locking and unlocking operations on the display screen;
when the OLED display screen is confirmed to be in the screen locking state, the OLED display screen can be controlled to enter a screen locking and unlocking mode, and a screen locking and unlocking program is started to execute screen locking and unlocking operations on the OLED display screen in the screen locking and unlocking mode so as to confirm that the OLED display screen can be normally used. After the screen locking and unlocking operation is performed on the OLED display screen, the OLED display screen may still have a problem or the OLED display screen may enter the screen locking state again (screen locking identification information of the OLED display screen in the screen locking state is read again under a preset storage path), and the like. Therefore, the corresponding screen locking and unlocking result may be that the screen locking and unlocking are failed or the screen locking and unlocking are successful. Different screen locking and unlocking results can be prompted through different prompting information.
If the screen locking and unlocking of the OLED display screen is successful, first prompt information can be output, the unlocking result of the screen locking and unlocking success of the OLED display screen is prompted, and meanwhile, the OLED display screen can be restarted to enable the OLED display screen to enter a normal operation state; if the screen locking and unlocking of the OLED display screen fails, second prompt information can be output, the unlocking result of the screen locking and unlocking failure of the OLED display screen is prompted, at the moment, the OLED display screen is restarted, and then the OLED display screen can enter the screen locking state again. The first prompt message and the second prompt message can be one or a combination of multiple prompt messages such as voice prompt message, text prompt message, display screen prompt message, indicator light prompt message or buzzer prompt message, and the combination is not specifically limited here, and can be selected by a user according to the use requirement of the user, so long as the screen locking result that the screen locking and unlocking are successful and the screen locking result that the screen locking and unlocking are failed can be effectively distinguished.
This embodiment is through when the display screen is in the shutdown state, receive the key operation that the display screen corresponds, and when the key operation is target key operation, respond to target key operation, make the display screen gets into lock screen unblock mode, and when the display screen is in the mode of preliminary unlocking, confirm the state information of display screen, if according to state information confirms the display screen is in the lock screen state, then control the display screen gets into lock screen unblock mode, right the display screen carries out lock screen unblock operation. That is, the display screen can enter the preparation state of screen locking and unlocking through the keys on the OLED display screen, and then the screen locking and unlocking operation is executed on the display screen when the display screen is confirmed to be in the screen locking state in the pre-unlocking mode, and screen locking and unlocking are not required to be performed in a serial port printing mode by means of the external terminal equipment of the computer. Because of need not external terminal equipment, can reduce risks such as system intrusion or information leakage, reduce the potential safety hazard, can be when the display screen leads to the lock screen because of the hardware is unusual moreover, the convenience of the improvement lock screen unblock of very big degree.
Based on the above embodiment, a second embodiment of the method for unlocking a lock screen of a display screen according to the present invention is provided, and referring to fig. 3, in this embodiment, the method for unlocking a lock screen of a display screen includes the following steps:
step S11: when the display screen is in a power-off state, receiving key operation corresponding to the display screen;
step S12: if the key operation is a target key operation, responding to the target key operation, enabling the display screen to enter a pre-unlocking mode, and confirming the state information of the display screen when the display screen is in the pre-unlocking mode;
step S13: if the display screen is confirmed to be in the screen locking state according to the state information, acquiring a starting parameter corresponding to the display screen;
step S14: generating a screen locking and unlocking instruction according to the starting parameters;
step S15: and responding to the screen locking and unlocking instruction, controlling the display screen to enter a screen locking and unlocking mode, and executing screen locking and unlocking operation on the display screen.
In this embodiment, when the OLED display screen enters the pre-unlocking mode and it is determined that the OLED display screen is in the screen locking state, a screen locking and unlocking instruction may be generated according to a start parameter required when the OLED display screen is started, so that the OLED display screen enters the screen locking and unlocking mode according to the screen locking and unlocking instruction, and the screen locking and unlocking operation is performed on the OLED display screen. That is, before the screen locking and unlocking operation is performed on the OLED display screen, the start parameters corresponding to the OLED display screen are acquired, so that a screen locking and unlocking instruction is generated according to the acquired start parameters. The start-up parameter may be a predetermined parameter, such as a parameter (OLED _ panel _ lock) for indicating that the OLED display is in a locked state.
The mode of generating the screen locking and unlocking instruction according to the acquired starting parameters may be as follows: and realizing the transmission and analysis of the starting parameters by means of a transfer function and an acquisition function in the starting loading program, and further generating a screen locking and unlocking instruction according to the analyzed starting parameters. Specifically, a transfer function (bootLoader) can be operated first to transfer the acquired start parameters to the acquisition parameters (getarges), then a real-time operating system (kernel) is started to operate a screen locking and unlocking program, the start parameters acquired by the acquisition function are analyzed to obtain analyzed start parameters, and then a screen locking and unlocking instruction is generated according to the analyzed start parameters.
Here, the process of analyzing the start parameter obtained by the obtaining function is actually a process of verifying the start parameter, and therefore, before generating the screen locking and unlocking instruction according to the analyzed start parameter, it is further necessary to determine whether the OLED display screen meets the screen locking and unlocking condition according to the analyzed start parameter. In an embodiment, whether the OLED display screen meets the screen locking and unlocking condition can be determined by comparing the analyzed starting parameter with a preset starting parameter (a preset starting parameter). If the analyzed starting parameter is inconsistent with the preset starting parameter, the OLED display screen does not meet the screen locking and unlocking condition; and if the analyzed starting parameters are consistent with the preset starting parameters, the OLED display screen meets the screen locking and unlocking conditions.
