[0003] Some existing backlit display devices can recognize screen colors and control the color changes of different LED strips in the backlight display device based on the screen color. Conventional backlit display devices generally also include Field Programmable Gate Array (FPGA), Universal Serial Bus (USB) interface, or High Definition Multimedia Interface (HDMI) components.

[0019] If the pluggable interface module has GPIO functionality, the process of obtaining the screenshot area corresponding to the target display cycle from the pluggable interface module is stopped.

[0020] Optionally, the screenshot area corresponding to the target display period is determined based on the latest received screenshot size and latest screenshot position, where the latest screenshot size and latest screenshot position refer to the last received screenshot size and latest screenshot position that are adjacent to the target display period.

[0025] Optionally, the pluggable interface module is in an active state and supports general-purpose input / output (GPIO) functions, including:

[0036] According to an embodiment of the present invention, a backlight display method is applied to a backlight display device, the backlight display device including a pluggable interface module and an LED strip.

[0037] As can be seen, the backlight display method proposed in this embodiment of the invention eliminates the need to determine the light strip to be lit by scaling the video signal image. Instead, it creates a virtual screen and extracts the video frame data corresponding to the edges of the virtual screen. This not only reduces the amount of data processing but also improves processing efficiency and shortens latency. Furthermore, it eliminates the need for FPGA and interface components such as USB or HDMI, thus reducing the device size. In addition, by providing data transmission and light strip lighting functions through a pluggable interface module, the need to deploy interface devices in the device is eliminated, further reducing its size.

[0049] This invention relates to display technology, specifically to a display method based on a backlight display device that supports displaying colors that correspond to video colors. During the execution of this method, the backlight display device can create a virtual screen associated with the video to be matched using a virtual display. Then, it acquires video frame data corresponding to the edges of the virtual screen to determine the color data corresponding to the video frame data, thereby controlling the backlight display device to display light that matches the color of the video frame data. The display method described in this invention creates a virtual screen using a virtual display, acquires video frame data based on the virtual screen, and then determines the color of the light strip to be illuminated based on the video frame data, thereby illuminating the corresponding light strip. It is evident that this invention eliminates the need to scale the video signal to determine the light strip to be illuminated; instead, it creates a virtual screen and extracts video frame data corresponding to the edges of the virtual screen. This not only reduces the amount of data processed but also improves processing efficiency and shortens the delay for screenshotting.

[0050] The backlight display device according to embodiments of the present invention provides an effect rendering means for video playback through a display method. The backlight display device includes a pluggable interface module and a light strip. The pluggable interface module can be used to connect to a USB device with general-purpose input / output (GPIO) functionality, and then transmit video frame data through the GPIO function of the USB device, so that the light strip of the backlight display device responds to the color of the video frame data for display. Therefore, the backlight display device provided by the embodiments of the present invention does not require the inclusion of an FPGA and interface components such as USB or HDMI, thus reducing the device size. Furthermore, by providing data transmission and light strip illumination functions through the pluggable interface module, the need for deploying interface devices in the device is eliminated, further reducing the size.

[0051] The following describes the technology of the embodiments of the present invention through examples.

[0052] See Figure 1 , Figure 1 A flowchart of a backlight display method according to an embodiment of the present invention is shown. This backlight display method can be applied to the aforementioned backlight display device. The method includes:

[0053] Step S101: When the pluggable interface module and the backlight display device are connected, the screenshot area corresponding to the target display period is obtained from the pluggable interface module according to the preset display period.

[0054] The most basic condition for obtaining the screenshot area corresponding to the target display period is that the pluggable interface module and the backlight display device are connected. The screenshot area corresponding to the target display period is the screen range determined based on the received screenshot size and position within a certain time period.

[0055] Optionally, both the screenshot size and the screenshot position can be fixed values ​​or dynamically adjustable.

[0056] Optionally, to detect whether the pluggable interface module and the backlight display device have a connection relationship, the status of the pluggable interface module can be monitored.

[0057] In some implementations, if the pluggable interface module establishes a connection with the backlight display device, it continues to detect whether the pluggable interface module supports GPIO function. If the pluggable interface module supports GPIO function, then the screenshot operation can be started, that is, according to the preset display cycle, the screenshot area corresponding to the target display cycle is obtained from the pluggable interface module.

[0058] In other implementations, if the pluggable interface module is disconnected from the backlight display device, the system continues to check whether the pluggable interface module supports GPIO functionality. If the pluggable interface module has GPIO functionality, the system stops processing the acquisition of the screenshot area corresponding to the target display cycle from the pluggable interface module, i.e., stops the screenshot service.

[0059] For example, the screenshot size and the screenshot position can be adjusted by an external adjustment component, which may include at least one of the following: a knob, an infrared sensor, or a button. The USB device uses GPIO to detect the status of the external adjustment knob, infrared sensor, button, etc., and adjusts its stored screenshot size and position in real time.

[0060] Step S102: Create a virtual screen according to the screenshot area.

[0061] The virtual screen is created by the virtual display based on the screenshot area corresponding to the target display period. The screenshot area corresponding to the target display period is determined based on the latest screenshot size and the latest screenshot position received. The latest screenshot size and the latest screenshot position refer to the last screenshot size and the latest screenshot position that are adjacent to the target display period.

[0062] In some implementations, the latest screenshot position and the latest screenshot size are first received. Then, it is checked whether the screenshot position of the current screenshot area is the same as the latest screenshot position, and whether the screenshot size of the current screenshot area is the same as the latest screenshot size. If the screenshot position of the current screenshot area is different from the latest screenshot position, or the screenshot size of the current screenshot area is different from the latest screenshot size, it indicates that the screenshot area has changed. At this time, the screenshot area corresponding to the previous cycle of the target display cycle needs to be changed to obtain the screenshot area corresponding to the target display cycle. That is, the latest screenshot position and the latest screenshot size are taken as the screenshot area corresponding to the target display cycle.

[0063] Step S103: Obtain the data of the video frame corresponding to the edge of the virtual screen to obtain the target video frame data.

[0064] The video frame data corresponding to the edge of the virtual screen refers to the video frame data at the edge of the screenshot area. This target video frame data serves as the basis for illuminating the light strip.

[0065] In step S104, if it is determined that the pluggable interface module supports the target transmission function, the pluggable interface module is called to control the light strip to light up. The color of the light strip after it is lit up matches the target video frame data so as to cooperate with the video frame for backlight display.

[0066] The pluggable interface module supports target transmission function, that is, the pluggable module contains an interface that can transmit data. Calling the pluggable interface module to control the light strip to light up means that the light strip lights up accordingly based on the target video frame data.

[0067] For example, a pluggable interface module supporting GPIO functionality can establish a connection between the pluggable interface module and a USB device module with GPIO functionality.

[0068] Corresponding to the above implementation steps, embodiments of the present invention also provide software, hardware, or a combination of software and hardware modules / units for performing the above implementation steps.

[0069] This invention also provides a backlight display device for implementing the above-described display method.

[0070] See Figure 2 , Figure 2 The present invention illustrates a backlight display device (hereinafter referred to as the device) according to an embodiment of the present invention, which can be used to implement... Figure 1 A schematic diagram of a backlight display method.

[0071] like Figure 2 As shown, the device may include: host device 21, USB device 22 and light strip 23.

[0072] Understandable Figure 2 This is merely an illustrative description and does not constitute a limitation on the embodiments of the present invention. In actual implementation, the backlight display device of the embodiments of the present invention may include more or fewer components, and the connection relationships between the components may also be different. For example, in some other embodiments, the backlight display device may also include a power supply component, etc. The embodiments of the present invention will not be described in detail here.

[0073] The host device 21 and the USB device 22 are components of the pluggable interface module. The host device 21 can be used to capture and process video frame data involved in steps S101 to S103, as well as control the lighting and extinguishing of the light strip 23. The USB device 22 can be used to store the data involved in steps S101 to S104, including the video frame data. In some implementations, the USB device 22 is a USB device with GPIO function, which establishes a connection with the light strip 23 through the GPIO function. The light strip 23 can be lit or extinguished in response to the instructions transmitted by the host device 21 through GPIO. The instructions of the host device 21 are generated by processing the data stored in the USB device 22.

[0074] The host device 21 is used to obtain the screenshot area, create a virtual screen based on the screenshot area, and obtain the video frame data corresponding to the edge of the virtual screen. The USB device 22 is used to store the screenshot position and screenshot size that constitute the screenshot area, and also to store the video frame data corresponding to the edge of the virtual screen. The light strip 23 is used to light up according to the video frame data corresponding to the edge of the virtual screen stored in the USB device 22.

[0075] The following section describes each part of the backlight display device in conjunction with the specific implementation process.

[0076] When the host device 21 determines that it has a connection with the backlight display device, it obtains the screenshot area from the USB device 22. Based on the obtained screenshot area, it creates a virtual screen through a virtual display. Then, it obtains the video frame data corresponding to the edge of the virtual screen and sends the video frame data to the USB device 22 for storage through the human interface device (HID) included in the host device 21. Based on the stored video frame data, the USB device 22 lights up the light strip 23 through its own GPIO function. The color of the light strip 23 after it is lit matches the video frame data.

[0077] Furthermore, the screenshot area stored in the USB device 22 is variable. When the USB device 22 detects a change or adjustment in at least one component such as an external adjustment knob, infrared sensor, or button via GPIO, it will adjust the stored screenshot position and size in real time. Then, within a period of time, the host device 21 obtains the current screenshot position and size stored in the USB device 22 and compares them with the screenshot position and size obtained in the previous period. If the screenshot position and size in the two periods are different, the current screenshot position and size are used to redetermine the screenshot area.

[0078] As can be seen, the backlight display device proposed in this embodiment of the invention uses a virtual display. A virtual screen is created based on the screenshot area, thereby acquiring video frame data corresponding to the edge of the virtual screen. This video frame data is then sent to a USB device for storage via HID. The USB device then outputs the video frame data to the LED strip via its GPIO, thereby illuminating the LED strip that matches the video frame data, achieving a corresponding backlight display effect during video playback. Furthermore, by adjusting the screenshot position and size, the screenshot area can be changed, thereby altering the video frame data acquired from the edge of the virtual screen, thus achieving a change in the LED strip display.

[0079] Figure 3 A schematic diagram of a backlight display device according to an embodiment of the present invention is shown. (Refer to...) Figure 3 A backlight display device, characterized in that it is applied to a backlight display equipment and includes: an acquisition module 31 and an execution module 32. Each unit module is used for execution... Figure 1 Some or all of the steps of the backlight display method shown.

[0080] Figure 3 The illustrated backlight display device can be understood as... Figure 2 The schematic backlight display device is implemented at the logic level. For example, some functions of the acquisition module 31 can be deployed in the host device 21, and other functions can be deployed in the USB device. Some functions of the execution module 32 can be deployed in the USB device.

[0081] For example, the acquisition module 31 is used to acquire a screenshot area corresponding to a target display period from the pluggable interface module according to a preset display period when the pluggable interface module and the backlight display device are connected; it is also used to acquire data of video frames corresponding to the edge of the virtual screen to obtain target video frame data; the execution module 32 is used to create a virtual screen according to the screenshot area; and it is also used to call the pluggable interface module to control the light strip to light up when it is determined that the pluggable interface module supports the target transmission function, wherein the color of the light strip after it is lit up matches the target video frame data to cooperate with the video frame for backlight display.
