In the display background light system of some embodiments, the cloud server 40 stores a corresponding relationship between RGB color values and light control commands, that is, each RGB color value has a corresponding light control command. The cloud server 40 analyzes the real-time display image after receiving the real-time display image to obtain RGB color values, and searches for light control instructions corresponding to the RGB color values according to the correspondence. This implementation utilizes the powerful data processing ability of cloud server 40 to resolve the real-time display picture and obtains light control command, greatly reduced communication module 30's hardware requirement to greatly reduced finished product cost.
In the display screen backlight system of some embodiments, referring to fig. 4, the display screen backlight system further includes a management terminal 60 in communication connection with the cloud server 40, the management terminal 60 sends the update content to the cloud server 40, and the cloud server 40 updates the corresponding relationship according to the update content. After the cloud server 40 updates the corresponding relationship between the RGB color values and the lighting control instructions, the control strategy of the backlight 10 is correspondingly changed, so that the display effect of the backlight 10 is better. While such changes do not require changes to the user side backlight 10, camera 20 and communication module 30, the backlight control algorithm of the prior art is fixed in the local hardware, and once purchased, the user cannot change the backlight control algorithm, and the user cannot enjoy the upgrading experience. This embodiment can continuously upgrade the update to RGB color value and light control command's corresponding relation, strengthens product competitiveness.
In some embodiments of the display backlight system, the backlight 10 is a light strip including beads with at least two colors, such as an LED light strip, and the light strip receives the light control command and then adjusts the color and brightness of the backlight 10 according to the light control command to emit light matching the real-time display image of the display 50.
In some embodiments of the display screen backlight system, the network environment in which the communication module 30 is located is dynamically changed, and the response time of the cloud server 40 is prolonged in the case of network speed reduction or network congestion. The communication module 30 of this embodiment determines whether the response time of the cloud server 40 exceeds a first preset time, and if the response time exceeds the first preset time, it indicates that the network speed is reduced or the network is congested. In order to reduce the response time, the resolution of the real-time display picture can be actively reduced, the transmission data volume is reduced after the resolution of the real-time display picture is reduced, and the response speed can be properly increased. Alternatively, when the resolution of the real-time display screen is reduced, the resolution may be reduced when the camera 20 captures the real-time display screen, and the resolution of the captured real-time display screen may also be reduced using the communication module 30. The present embodiment improves the response speed by reducing the resolution of the display screen, ensuring that the backlight 10 can change as the screen content of the display screen 50 changes.
In the display screen backlight system of some embodiments, in the process of detecting the real-time image, if the cloud server 40 detects that the real-time display image is a preset shutdown image, such as a lock screen image or a black screen image, the cloud server 40 generates a shutdown instruction, and sends the shutdown instruction to the backlight 10 and the camera 20 through the communication module 30, so that the backlight 10 and the camera 20 enter a shutdown state. Alternatively, to prevent false triggering, timing is started after the cloud server 40 detects that the real-time display image is the preset shutdown image, and if the real-time display image detected after the second preset time is still the preset shutdown image, the cloud server 40 generates a shutdown instruction. According to the embodiment, the backlight 10 and the camera 20 are automatically turned off after the user shuts down or locks the screen, the user does not need to manually turn off the backlight, the user experience is improved, and electric energy is saved.
In the display screen backlight system of some embodiments, if the cloud server 40 detects that the real-time display image is a preset standby image, the cloud server 40 generates a standby instruction, and sends the standby instruction to the backlight 10 through the communication module 30, so that the backlight 10 enters a standby state. Further, if the cloud server 40 detects that the real-time display image is a working image, the backlight 10 is restarted, where the images other than the preset shutdown image and the preset standby image are both working images. That is, when the cloud server 40 detects that the real-time display screen is not the preset shutdown screen or the preset standby screen, it considers that the working screen is detected. This embodiment allows the backlight 10 to enter a standby state when the user is not using the display screen, and power can be saved.
In some embodiments of the display screen backlight system, the backlight 10 has a plurality of backlight types, each backlight type having a different number and configuration of lamp sets, resulting in different light control commands for different backlight types for the same real-time display. In order to generate a light control instruction corresponding to each type of backlight, the communication module 30 of this embodiment stores the type of backlight, the cloud server 40 stores an instruction coding algorithm corresponding to each type of backlight, the instruction coding algorithm is used for generating the light control instruction according to the RGB color value, and the instruction coding algorithms corresponding to different types of backlights are different. It can be understood that for the same real-time display picture, the light control instructions generated by the instruction coding algorithms corresponding to different backlight models are different. The communication module 30 sends the background light model to the cloud server 40, and the cloud server 40 generates the light control command according to the real-time display picture and by using the command coding algorithm corresponding to the background light model. That is, the cloud server 40 firstly analyzes the real-time display image to obtain RGB color values, and then generates the light control commands corresponding to the RGB color values by using the command encoding algorithm corresponding to the background light model. In this embodiment, only the types of the backlights need to be stored in the communication module 30 purchased by the user, and the instruction encoding algorithms of different types of backlights run on the cloud server 40, so that the requirements of hardware purchased by the user are greatly reduced, and the cost of finished products is greatly reduced.
In the display screen backlight system of some embodiments, the existing instruction encoding algorithm of the cloud server 40 may be updated, and the specific updating process is as follows: the management terminal 60 sends the algorithm update object and the algorithm update content to the cloud server 40, and the cloud server 40 searches for the instruction encoding algorithm specified by the algorithm update object and then updates the instruction encoding algorithm using the algorithm update content. The embodiment keeps updating the instruction encoding algorithm, so that the user can continuously improve the use experience.
In the display screen backlight system of some embodiments, a command encoding algorithm of the cloud server 40 may be added, that is, a command encoding algorithm that the cloud server 40 does not have is added, and the specific addition process is as follows: the management terminal 60 sends the new command encoding algorithm and the new backlight model to the cloud server 40, and the cloud server 40 stores the command encoding algorithm, the new backlight model, and the corresponding relationship between the command encoding algorithm and the new backlight model. It can be seen that only the backlight 10 needs to be developed when a new product is developed, and meanwhile, the type of the backlight in the communication module 30 needs to be modified, so that the development difficulty is greatly reduced, and the research and development cost is reduced.
In the display screen backlight system of some embodiments, the existing instruction encoding algorithm of the cloud server 40 may be deleted, and the specific deletion process is as follows: the management terminal 60 sends the algorithm deletion object to the cloud server 40, and the cloud server 40 searches for the instruction encoding algorithm specified by the algorithm deletion object and then deletes the algorithm.
