[0037] The realization of matrix backlight requires a matrix backlight controller to control it. When the display terminal system is powered on, the display terminal main control chip needs to be initialized to a certain level before sending data to the matrix backlight controller. This will cause the display terminal to be unable to control the matrix backlight when it is turned on, causing the screen to flicker at the moment of startup, affecting the user experience.

[0038] A storage area is opened in the matrix backlight controller to store the matrix backlight data. When the display terminal system is fully initialized, the matrix backlight data of the current system startup image is calculated, and then the matrix backlight data is sent to the matrix backlight controller, which then stores the matrix backlight data in the storage area. The next time the system is turned on, before receiving a new matrix backlight control command, the matrix backlight controller uses the matrix backlight data in the storage area for display. This improves the user experience and solves the problem of screen flickering at the moment of startup.

[0070] If not, determine the matrix backlight data corresponding to the new preset startup picture based on the matrix backlight algorithm.

[0071] The embodiment of the present invention provides a matrix backlight control method for a display terminal. Refer to Figure 2 , Figure 2 It is a schematic flowchart of the first embodiment of a matrix backlight control method for a display terminal according to the present invention.

[0072] In this embodiment, the matrix backlight control method of the display terminal includes:

[0073] Step S10: After the display terminal is fully initialized, obtain the preset startup picture of the current display terminal system.

[0074] Matrix backlight, also known as dynamic backlight, can determine the lighting brightness of the LED light sources in the corresponding areas of the backlight panel according to the brightness of the input image. This can not only improve the contrast but also save energy, and is especially suitable for motion pictures with a relatively high switching rate.

[0075] The implementation of matrix backlight requires a matrix backlight controller to control. When powering on the display terminal system, the main control chip of the display terminal needs to be initialized to a certain extent before it can send data to the matrix backlight controller, which will cause the problem of screen flashing at the moment of startup and affect the user experience.

[0076] Therefore, after the display terminal system is fully initialized, obtain the preset startup picture of the current display terminal system. Before the display terminal system is fully initialized, perform startup display with the matrix backlight data of the preset startup picture to prevent screen flashing at startup. In a preferred embodiment, the display terminal is a television.

[0077] Step S20: Determine the matrix backlight data corresponding to the preset startup picture based on the matrix backlight algorithm.

[0078] After the display terminal system is fully initialized, use the matrix backlight algorithm originally available in the display terminal system to determine the matrix backlight data corresponding to the display of the preset startup picture, which reduces the development work and also helps the matrix backlight actions to be consistent. At the same time, calculate and save the matrix backlight display data corresponding to the startup picture without the user's perception, so that before the next startup when the system is not fully initialized or starts to be initialized, the matrix backlight function can be realized by the matrix backlight controller retrieving the matrix backlight data.

[0079] Step S30: At the next startup, control the matrix backlight based on the matrix backlight data to achieve the matrix backlight control when displaying the preset startup picture.

[0080] After calculating and storing the matrix backlight data corresponding to the preset startup picture, at the next startup, before receiving a new matrix backlight control command, the matrix backlight controller uses the matrix backlight data in the storage area for display to display the preset startup picture.

[0081] In this embodiment, after the display terminal is fully initialized, obtain the preset startup picture of the current display terminal system; determine the matrix backlight data corresponding to the preset startup picture based on the matrix backlight algorithm; at the next startup, control the matrix backlight based on the matrix backlight data to achieve the matrix backlight control when displaying the preset startup picture.

[0082] After the display terminal system is fully initialized, calculate and store the matrix backlight data of the preset startup picture of the current system. When starting up next time, before receiving a new matrix backlight control command, the matrix backlight controller calls the matrix backlight data for display. Thus, the matrix backlight control can be performed when the display terminal is powered on and initialized, and the function of preventing screen flashing of the display terminal can be realized without the user noticing.

[0083] Optionally, the matrix backlight control method of the display terminal further includes:

[0084] Determine a storage area in a preset memory;

[0085] Store the matrix backlight data in the storage area;

[0086] When starting up next time, retrieve the matrix backlight data from the storage area.

[0087] Open up a storage area in the preset memory related to the matrix backlight controller. This storage area may be a section in the Flash (flash memory) of the matrix backlight controller, or a section or all of the Flash externally connected to the matrix backlight controller, or a dedicated external storage device specifically connected to the matrix backlight controller. Or it can also be the memory related to the main control chip of the display terminal. After the main control chip of the display terminal calculates the matrix backlight data, it is directly stored in the memory related to the main control chip of the display terminal. When starting up next time, the matrix backlight controller reads the matrix backlight data from the memory related to the main control chip of the display terminal. In this embodiment, the position and type of the memory for storing the matrix backlight data are not limited, as long as the main control chip of the display terminal can write data and the matrix backlight controller can read data. The stored matrix backlight data is data such as the overall brightness value of the matrix backlight and the matrix backlight control data.

[0088] In this embodiment, open up a storage area in the matrix backlight controller for storing the matrix backlight data. After the display terminal system is fully initialized, calculate the matrix backlight data corresponding to the startup picture of the current system, and then send the matrix backlight data to the matrix backlight controller. The matrix backlight controller then stores the matrix backlight data in this storage area. When starting up next time, before receiving a new matrix backlight control command, the matrix backlight controller uses the matrix backlight data in the storage area for display control. Thus, the user experience is improved and the problem of screen flashing at the moment of startup is solved.

[0089] After the display terminal system is fully initialized, the matrix backlight data corresponding to the current system startup picture can be obtained through the matrix backlight control related interface, and then the matrix backlight data is sent to the matrix backlight control related interface, and this interface can output the corresponding matrix backlight control parameters, such as the matrix backlight control matrix, etc. The display terminal system sends the matrix backlight data to the matrix backlight controller through the interface related to the matrix backlight controller, and the matrix backlight controller stores the corresponding matrix backlight data in the preset storage area.

[0090] Optionally, before the step of determining the storage area in the preset memory, it further includes:

[0091] Obtain the number of partitions for matrix backlight control, and determine the size of the storage area based on the number of partitions.

[0092] Allocate a storage area in the matrix backlight controller to store the matrix backlight data. This is implemented on the matrix backlight controller of a certain display terminal: a region is divided on the matrix backlight controller IC to store the matrix backlight control data, and the size of this data is related to the number of matrix backlight partitions that the matrix backlight controller needs to control. For example, if the matrix backlight controller has 1024 partitions, then the size of this partition is also 1024 bytes. Each byte corresponds to the data of one partition.

[0093] Optionally, before the step of controlling the matrix backlight based on the matrix backlight data, it further includes:

[0094] Judge whether the display screen of the display terminal is initialized;

[0095] If the display screen is initialized, then execute the step of controlling the matrix backlight based on the matrix backlight data.

[0096] Optionally, after the step of judging whether the display screen is initialized, it further includes:

[0097] If the display screen is not initialized, then execute the step of judging whether the display screen of the display terminal is initialized.

[0098] At present, the main control chips of display terminals are all multi-core. When the display terminal is powered on, a CPU (central processing unit) will be started by default, and then this CPU will initialize the parameters and corresponding devices required for the work of other CPUs. After the initialization is completed, the system will start other CPUs. The matrix backlight controller is generally a simple MCU (Micro Controller Unit) with relatively simple functions. It can be initialized as soon as it is powered on, and then it will wait for the display terminal CPU to send it a control command. It can be seen that the matrix backlight controller should be initialized earlier than the display terminal CPU, so that it can start working normally before the display terminal system is fully started.

[0099] In one embodiment, the startup process of the display terminal is as follows:

[0100] 1. After power-on, the system first powers on the display terminal main control chip. After the display terminal main control chip is powered on, the display terminal main control chip first runs the uboot (boot loader) according to the configuration; after power-on, the system also powers on the matrix backlight controller, and the matrix backlight controller begins to initialize.

[0101] 2. Then uboot initializes each module of the system: such as screen display, related IO (input & output) port configuration, register configuration, EMMC (embedded MultiMedia Card) and other peripheral configurations; but at the same time, the matrix backlight controller has already completed initialization and is waiting for the screen display initialization to complete. After the screen displays the first frame of the picture, the backlight will be turned on to let the user see the image of the preset boot picture.

[0102] Therefore, before the matrix backlight controller retrieves the matrix backlight data from the storage area to perform matrix backlight control and display the preset startup image, it is necessary to determine whether the display screen has been initialized. If the display screen has been initialized, the matrix backlight is controlled based on the matrix backlight data, so that the corresponding matrix backlight data is used to perform matrix backlight control when the preset startup image is displayed at startup. If the display screen has not been initialized, the step of determining whether the display screen has been initialized is performed.

[0103] Optionally, after the step of controlling the matrix backlight based on the matrix backlight data to realize the matrix backlight control when displaying the preset startup picture, the method further includes:

[0104] Determining whether the initialization degree of the display terminal is greater than a preset threshold;

[0105] If the initialization degree of the display terminal is greater than a preset threshold, switch the preset startup picture to a startup animation or other content to be displayed.

[0106] The current matrix backlight needs the display terminal system to be initialized to a certain extent to complete tasks other than initialization. This is because the main control chip of the display terminal needs to continuously obtain information about the current display picture. However, when the display terminal is just powered on, the display terminal system is not fully initialized. Only a CPU is initialized, or even a CPU is not fully started. At this time, it is not sufficient to complete the function of continuously obtaining information about the current display picture.

[0107] When the display terminal is just powered on, a picture will be displayed until the display terminal system reaches a certain level before switching this picture to a startup animation or other display content. During this process, no other pictures will be switched. Therefore, after the matrix backlight controller retrieves matrix backlight data from the storage area for matrix backlight control and displays the preset startup picture, it is determined whether the initialization degree of the display terminal is greater than the preset threshold. If the initialization degree of the display terminal is greater than the preset threshold, it means that the initialization process of the display terminal can already support the display terminal system to display other pictures, startup animations or videos and other content to be displayed, and the preset startup picture can be switched to a startup animation or other content to be displayed. Thus, when the display terminal is powered on, different contents are displayed corresponding to the initialization degree of the display terminal, and the startup screen conversion is completed smoothly.

[0108] Optionally, the matrix backlight control method of the display terminal further includes:

[0109] When updating the current display terminal system, determine whether the new preset startup picture of the new current display terminal system is the same as the preset startup picture of the current display terminal system;

[0110] If not, determine the matrix backlight data corresponding to the new preset startup picture based on the matrix backlight algorithm.

[0111] In this embodiment, the current display terminal system may be updated, and the preset startup picture of the current display terminal system may also be replaced accordingly. Therefore, when updating the current display terminal system, it is necessary to determine whether the preset startup picture has been replaced, and it is necessary to determine whether the preset startup picture of the new display terminal system is the same as that of the current display terminal system. If they are different, when powering on for the first time after the update, the matrix backlight is controlled with the matrix backlight data pre-stored in the previous version of the display terminal system, and the preset startup picture of the previous display terminal system is displayed. After the current updated display terminal system is fully initialized, based on the matrix backlight algorithm, the new matrix backlight data corresponding to the new preset startup picture is determined, and the system version, startup picture, and matrix backlight data are replaced correspondingly. Similarly, even if the display terminal system is replaced, there will be no problem that the display terminal cannot control the matrix backlight during startup or the screen flashes instantly at startup. The function of preventing screen flashing of the display terminal is also realized without the user noticing, and the matrix backlight can be controlled when the display terminal is initialized when powered on.
