Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a display control method provided by an embodiment of the present application. The specific flow of the display control method may be as follows:

101. When it is detected that the device is powered on, read the screen parameter file of at least one driver chip in the display screen of the device in real time, and the screen parameter file includes real-time screen parameters when the device is powered on.

Among them, the screen parameters are output by the driver chip and act on the display screen to control the display of the display screen. The screen parameters include the basic width and height of the screen, refresh rate, brightness and resolution, etc.

Among them, the screen parameter file is used to store the screen parameters. The screen parameter file can be a file with an extension of .txt. The screen parameter file can be stored in the driver chip or in the device memory. After the driver chip loads the screen parameter file, The display screen can be controlled to display according to the screen parameters in the screen parameter file.

Among them, the driver chip includes microelectronic devices (IC, Integrated Circuit) or embedded multimedia card (EMMC, Embedded Multi Media Card).

Among them, in order to ensure the accuracy of the screen parameters in the screen parameter file, the manufacturer will rewrite the screen parameters in the device when the device is turned on, so as to ensure that the display screen can follow the standard and pre-defined screen parameters after each boot. Display, that is, after the device displays abnormally, in most cases, the display style of the display can be adjusted or restored by restarting the device;

Therefore, when the device is turned on, obtaining the screen parameters of the device can accurately obtain the display parameters displayed on the screen before the device is turned off, and by verifying this part of the display parameters, it can be determined whether this part of the display parameters has changed, for example, This part shows whether the parameters are out of order due to system reasons or software abnormalities.

Wherein, the screen parameter file can be read according to the loading path of the screen parameter file, that is, optionally, in some embodiments, the step "read the screen parameter file of at least one driver chip in the display screen of the device in real time", specifically Can include:

Obtain the screen parameter path of at least one driver chip in the display screen, where the screen parameter path is the configuration path of the screen parameter file for configuring the driver chip last time before the device is powered on;

Read the screen parameter file of the driver chip according to the screen parameter path.

Wherein, the screen parameter path is the path for the driver chip to load the screen parameter file, and the screen parameter file of the driver chip can be obtained according to the screen parameter path, wherein, the acquisition of the screen parameter path can be obtained according to a pre-stored path list, and according to the screen parameter path The obtained screen parameter file can improve the accuracy of obtaining the screen parameter file.

Among them, in order to ensure the accuracy of the screen parameters, a backup screen parameter file can be set in the device. After the screen parameter file of the driver chip is destroyed, the backup screen parameter file can be loaded as needed, and the screen parameters in the backup screen parameter file can be used. Controlling the display of the display screen, that is, optionally, in some embodiments, the step of "reading the screen parameter file of at least one driver chip in the display screen of the device in real time" may specifically include:

Obtain the backup screen parameter path of at least one driver chip in the display screen, the backup screen parameter path is the backup path of the last backup screen parameter file of the driver chip before the device leaves the factory;

The backup screen parameter file of at least one driver chip is respectively read according to the backup screen parameter path.

Among them, the backup screen parameter file can be a backup of the set screen parameter file. When the real-time screen parameter file loaded by the driver chip in real time is abnormal, the backup screen parameter file can be automatically loaded, and the screen parameters in the backup screen parameter file can be used to control the display. Therefore, when the backup screen parameter file dominates the display of the display screen, it is necessary to detect the screen parameters in the backup screen parameter file when starting up. Therefore, in the embodiment of this application, according to the backup screen parameter file The backup screen parameter path obtains the backup screen parameter file and obtains the backup screen parameter file, which is convenient for verifying the backup screen data in the backup screen parameter file, and the acquisition of the backup screen parameter path also realizes the backup screen parameter file accurate positioning.

102. Obtain the setting screen parameters of the driver chip when it leaves the factory.

Among them, setting the screen parameters is set by the manufacturer according to the size of the screen, the needs of users or the needs of the market before leaving the factory. Setting the screen parameters often makes the display of the screen achieve the best effect. The screen parameters in the screen parameter files that can be loaded should also be synchronized with the setting screen parameters.

Wherein, the setting screen parameters can be obtained according to the data released by the manufacturer, or according to the display parameters pasted on the device, or according to the instruction manual of the device.

103. When the real-time screen parameters of each driver chip are the same as the corresponding setting screen parameters, keep the real-time screen parameters in the screen parameter file unchanged.

Among them, when the real-time screen parameters of the driver chip are the same as the set screen parameters, it means that the screen parameters in the screen parameter file loaded by the driver chip have not been modified. In this case, the real-time screen parameters in the screen parameter file can be kept No change, that is, there is no need to rewrite the screen parameters during this boot, which reduces the number of writes to the driver chip and improves the service life of the driver chip.

Wherein, it is possible to verify whether the two screen parameters are the same according to the hash value of the real-time screen parameter and the set screen parameter, that is, optionally, in some embodiments, the step "when the real-time screen parameter of each driver chip When it is the same as the corresponding setting screen parameters, then keep the real-time screen parameters in the screen parameter file unchanged", the details can include:

Obtain the verification code file corresponding to the setting screen parameters, and obtain the setting hash value of the setting screen parameters;

performing a hash operation on the real-time screen parameters to obtain a real-time hash value of the real-time screen parameters;

According to the set hash value and the real-time hash value, it is determined whether the set screen parameter is the same as the real-time screen parameter.

Among them, the hash value comparison method is also called message digest algorithm (MD5, Message-Digest Algorithm) check, according to the comparison of the set hash value of the set screen parameters and the hash value of the real-time screen parameters, it can be accurately Verify that the setting screen parameters are the same as the real-time screen parameters.

Among them, in order to ensure the accuracy of the setting screen parameters, the manufacturer generally sends a check code file for the setting screen parameters at the same time as sending the setting screen parameters. According to the check code file, the setting screen parameters can be obtained. Set the hash value, when verifying the real-time screen parameters, the real-time hash value of the real-time screen parameters can be generated, and the comparison between the set hash value and the real-time hash value can improve the verification of the set screen parameters and Whether the real-time screen parameters have the same efficiency, wherein, the set hash value can also be directly hashed and generated according to the set screen parameters.

Wherein, when the real-time screen parameters of the target driver chip are different from the corresponding setting screen parameters, the screen parameter file of the target driver chip is updated according to the setting screen parameters.

Wherein, the real-time screen parameters are updated by setting screen parameters, so that the real-time screen parameters and the setting screen parameters can be kept in sync, so that the display screen can be displayed according to factory requirements.

Among them, when the device is turned on and it is detected that the set screen parameters are different from the real-time screen parameters, updating the real-time screen parameters can restore the normal display of the display screen after the device is powered on. For example, when the display screen of the device displays abnormally, you can By restarting the device, the display screen style of the device can be reloaded correctly.

Wherein, when updating the screen parameters of the driver chip, the corresponding method can be selected according to the number of the driver chips to update, that is, optionally, in some embodiments, the step "update the screen parameters of the target driver chip according to the set screen parameters reference file to be updated”, which may include:

Obtain the number of target chips of the target driver chip, and the number of target chips is at least one;

Determine the screen parameter file update method of the target driver chip according to the number of target chips;

Update the screen parameter file of the target driver chip according to the screen parameter file update method and set screen parameters.

Wherein, according to the quantity of the driving chips, different updating methods are selected to update the driving chips, which can improve the updating efficiency of the driving chips.

For example, when there is only one driver chip, the real-time screen parameters can be updated directly according to the set screen parameters. ways", which may specifically include:

The screen parameter file of the target driver chip is updated directly according to the setting screen parameters of the target driver chip.

Among them, there is no interaction between a single driver chip and other driver chips, and the device can complete the display control of the display screen according to a single driver chip. Therefore, the screen parameters for a single driver chip can be directly updated according to the set screen parameters, and the update efficiency higher.

For example, please refer to Figure 3. 4K HDTV is designed with a single driver chip. The driver chip for 4K HDTV can be updated directly according to the set screen parameters. The specific update process includes:

110. Load the screen parameter path of the driver chip;

111. Detect whether the 4K screen parameters need to be synchronized, that is, check whether the real-time screen parameters are consistent with the set screen parameters. When the real-time screen parameters are consistent with the set screen parameters, there is no need to update the real-time screen parameters. When the setting screen parameters are inconsistent, the real-time screen parameters need to be updated according to the setting screen parameters.

In addition, when there are two driver chips, there will be interaction between the two driver chips, and the two driver chips work together to control the display of the display screen. Therefore, for the situation of two driver chips, one of the One driver chip updates the screen parameters, and then uses the updated driver chip to update the screen parameters of the other driver chip, that is, optionally, in some embodiments, the step "determines the screen parameters of the target driver chip according to the number of target chips." "Refer to file update method", which may include:

Selecting the first target driver chip from the two target driver chips;

Update the first screen parameter file of the first target driver chip according to the setting screen parameters of the first target driver chip;

After the first screen parameter file is updated successfully, the second screen parameter file of the second target driver chip is updated according to the updated first screen parameter file and the setting screen parameters of the second target chip.

Among them, for the display control of the two driver chips, there is a process of data transmission and interaction between the two driver chips, so it is possible to update one of the driver chips first, and then use the updated driver chip to update the other non-updated driver chip. The driver chip can be updated, which can improve the update efficiency of the driver chip.

For example, please refer to Figure 4. An 8K UHD TV mounts an 8K driver chip on the basis of a 4K driver chip to complete the 8K display on the display screen. Therefore, the screen parameters driven by the 8K driver chip are transmitted from the 4K driver chip. Therefore, when updating the screen parameters of the 8K driver chip, the 4K driver chip can be updated first, and then the 8K driver chip can be updated by using the updated 4K driver chip to improve the screen parameter update of the driver chip. The specific process of updating the screen parameters of the 8K driver chip includes:

121. First check whether the screen parameter data of the 4K driver chip needs to be updated. When the real-time screen parameter data of the 4K driver chip is consistent with the set screen parameter data, there is no need to update the screen parameter data of the 4K driver chip. Otherwise, it needs to be updated. Update the screen parameter data of the 4K driver chip;

122. After the 4K screen parameter data is updated, check whether the screen parameter data of the 8K driver chip needs to be updated. When the screen parameter data of the 8K driver chip needs to be updated (that is, the real-time screen parameter data of the 8K driver chip and the corresponding setting screen parameter When the data is inconsistent), obtain the setting screen parameter data of the 8K driver chip from the 4K driver chip, and update the real-time screen parameter data of the 8K driver chip. Otherwise, the screen parameter data of the 8K driver chip does not need to be updated.

Among them, the setting screen parameters include setting parameter names and setting parameter values, and the real-time screen parameters include real-time parameter names and real-time parameter values. Therefore, according to the parameter names of the setting screen parameters and real-time screen parameters, The parameter value corresponding to the parameter name is updated, that is, optional, in some embodiments, the step "update the screen parameter file of the target driver chip according to the set screen parameters", specifically may include:

Obtain the screen parameter path of loading the screen parameter file in the target driver chip;

According to the screen parameter path, setting parameter name and real-time parameter name, replace the real-time parameter value in the target driver chip with the setting parameter value.

Among them, updating the parameter value corresponding to the parameter name according to the parameter name can improve the accuracy of parameter updating, and the accurate positioning of the screen parameter to be updated can be realized by using the screen parameter path.

Wherein, updating the screen parameters can be implemented by replacing the parameter values corresponding to the parameter names, that is, optionally, in some embodiments, the step "according to the screen parameter path, the setting parameter name and the real-time parameter name, set The real-time parameter value in the target driver chip is replaced with the set parameter value", which can specifically include:

Load the screen parameter path to get the screen parameter file of the target driver chip;

According to the setting parameter name and real-time parameter name, replace the real-time parameter value in the screen parameter file with the setting parameter value.

Among them, according to the screen parameter path of the screen parameter file, the screen parameter file is loaded, and the parameter value corresponding to the parameter name in the screen parameter file is replaced to realize the update of the real-time screen parameters, which is convenient and quick.

Among them, in order to ensure the normal display of the display parameters, the manufacturer will back up a screen parameter file in the device. When the display is abnormal, the backup screen parameter file can be loaded by the driver chip, and the backup screen parameter file can be used to control the display of the display screen. For control, backup screen parameters are stored in the backup screen parameter file, wherein the backup screen parameter file is a backup of the setting screen parameter file, therefore, the setting screen parameter can include the backup screen parameter, that is, optional, in some In the embodiment, the step "update the screen parameter file of the target driver chip according to the set screen parameters" may specifically include:

Obtain the screen parameter path of the screen parameter file for loading the target driver chip and obtain the backup screen parameter path for loading the backup screen parameter file;

Replace the screen parameter path with the backup screen parameter path.

Among them, according to the replacement of the screen parameter path, the driver chip directly loads the screen parameters in the backup screen parameter file. After uploading the file, the driver chip actually directly loads the setting screen parameters, which has the function of making the display screen display normally, and achieves the function of updating the display parameters of the display screen.

In addition, the screen parameters can be obtained directly from the backup screen parameter file, and the corresponding screen parameters can be updated, wherein, the backup screen parameters include backup parameter names and backup parameter values, and the real-time screen parameters include real-time parameter names and real-time parameter values, that is, Optionally, in some embodiments, the step "update the screen parameter file of the target driver chip according to the set screen parameters" may specifically include:

According to the screen parameter path, the backup parameter name and the real-time parameter name, replace the real-time parameter value in the target driver chip with the backup parameter value.

Among them, the screen parameters of the backup screen parameter file are the backup of the set screen parameters, therefore, the real-time screen parameters can also be updated directly according to the backup screen parameter file. The replacement of the parameter value can realize the updating of the real-time screen parameters loaded by the driver chip.

Among them, when the screen parameters are entered in the device for the first time, the real-time screen parameters loaded by the driver chip are not there, that is, the real-time screen parameters are empty. At this time, a new screen parameter path can be created. According to the screen parameter path and the setting screen parameters to create a screen parameter file so that the display screen can be displayed normally, that is, optional, in some embodiments, the step "update the screen parameter file of the target driver chip according to the set screen parameters" may specifically include:

Create a new screen parameter path loaded by the target driver chip;

Create a new screen parameter file according to the new screen parameter path and set screen parameters.

Wherein, according to the new screen parameter path, the loading of the newly created screen parameter file can be realized, and the display of the display screen can be controlled after the driver chip loads the screen parameters in the newly created screen parameter file.

Among them, please refer to Figure 5, the creation of the screen parameter path and screen parameter file is also applicable to the configuration of the screen parameters, for example:

131. First detect the screen parameter path file, the driver chip needs to load multiple screen parameter files to control the display of the display screen, and in the process of configuring the screen parameters, some screen parameter files are lost due to the influence of the system or software;

132. At this time, it is necessary to create a new screen parameter file and the corresponding screen parameter path, or, the screen parameter file of some devices needs to be reconfigured. For example, for export products, it is necessary to add screen parameters such as country, region, and language. For this In this case, it is necessary to check whether there are corresponding screen parameters in the existing screen parameter file. If there is no such screen parameter (the absence of corresponding screen parameter means that there is no corresponding screen parameter path and screen parameter file), a new screen parameter file needs to be created. and the corresponding screen parameter path, and then configure and load the corresponding screen parameters, and the configuration and loading process is similar to the update of the screen parameter file above, for example:

133. Write the screen parameter path into the driver chip;

134. Load the screen parameter path;

135. Detect whether the screen parameters need to be synchronized, and synchronize the screen parameter data according to the detection results. Among them, the information summary algorithm (MD5, Message-Digest Algorithm) verification method checks whether the real-time screen parameters and the set screen parameters are always verified. When the real-time screen parameters are consistent with the set screen parameters, there is no need to update the real-time screen parameters. When the real-time screen parameters If it is inconsistent with the setting screen parameters, it will be updated according to the setting screen parameters and real-time screen parameters.

Wherein, in the embodiment of the present application, the update of the screen parameters may also be driven by VBE, the data update process is converted into a script file, and the script file is executed to realize the update of the screen parameters.

In the embodiment of this application, in the process of updating the screen parameter file, the screen parameters in the screen parameter file can also be updated according to the debug mode (debug mode), read the flag of the debug mode, and set the flag to In the screen parameter file, use the VBE driver to write the identification bit into the corresponding directory, such as the bin directory.

104. Control the display screen to display according to the screen parameter file.

Among them, the driver chip is loaded into the screen parameter file, and the screen parameters in the screen parameter file are output to the display screen to control the display of the display screen. For example, according to the screen parameters in the screen parameter file, adjust the screen base width, height, Refresh rate, brightness and resolution, etc.

Wherein, the screen parameters are stored in the form of a screen parameter file, which facilitates the updating of the screen parameters in the screen parameter file and the adjustment of the display screen parameters.
