[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0040] It should be noted that if there is no conflict, the various features in the embodiments of the present application can be combined with each other, and all are within the protection scope of the present application. In addition, although functional module division is performed in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device or the flowchart. Furthermore, the terms "first", "second", "third", etc. used in the present application do not limit the data and the execution order, but are only used to distinguish the same items or similar items with basically the same functions and effects.
[0041] As Figure 1 shown, the embodiments of the present application provide a method for improving the data accuracy of an LED display screen, and the method includes:
[0042] Step 110: Obtain video data.
[0043] Step 120: Perform bit-width reduction compensation on the video data.
[0044] In the embodiments of the present application, first, video data needs to be obtained, and then bit-width reduction compensation is performed on the video data. Specifically, a target bit-width is determined, where the target bit-width is less than the bit-width of the video data, and the video data is segmented; using interpolation technology, the data in each segment is reduced to the target bit-width; each segment with the reduced bit-width is recombined to generate video data with bit-width reduction compensation.
[0045] First, determine the target bit-width. According to actual requirements and system limitations, a target bit-width is determined, and this target bit-width is less than the bit-width of the video data. For example, the target bit-width can be 64 pixels.
[0046] Next, segment the video data. The video data is segmented according to the target bit-width to obtain a series of sub-images or sub-video segments.
[0047] Then, using interpolation technology, the data in each segment is reduced to the target bit-width. For the data points in each sub-image or sub-video segment, if their number of bits is less than the target bit-width, an interpolation algorithm is used to estimate and fill in the missing data points. The interpolation algorithm can predict and infer based on adjacent data points to generate new data points.
[0048] Finally, each segment with the reduced bit-width is recombined to generate video data with bit-width reduction compensation. Each segment with the reduced bit-width is recombined in a certain order and rule to form video data with bit-width reduction compensation. For example, multiple sub-images or sub-video segments can be merged into a large image or large video.
[0049] Step 130: Obtain the reduced video data and the remainder.
[0050] Step 140: Select the video data to be output for the next X frames according to the remainder.
[0051] In the embodiments of the present application, by obtaining the reduced video data and the remainder, and selecting the video data to be output for the next X frames according to the remainder. Exemplarily, obtain the video data P1 after reducing the video data from 25 bits to 16 bits, and the remainder P2. Determine the video data Pa, Pb, Pc for the next 3 frames according to P2, where
[0052]
[0053]
[0054]
[0055] In the next three frames, drive the pixel output according to Pa, Pb, and Pc respectively.
[0056] The method for improving the data accuracy of the LED display screen provided by the embodiment of the present application obtains video data, then performs bit-width reduction compensation on the video data, then obtains the reduced video data and the remainder, and finally selects the video data to be output in the next X frames according to the remainder, thereby reducing the influence brought by the error generated by the bit-width reduction and making the display screen color more accurate.
