Embodiment 1

[0015] Embodiment 1: The first thing in this embodiment is to design the video data conversion on the special-shaped LED screen. It is necessary to extract the video data, read it through the control system and light up the special-shaped LED screen.

[0016] In order for the special-shaped LED screen to be able to display video images, it is necessary to provide video files and data related to the special-shaped screen circuit. The data generally includes the following information:

[0017]1. Line number: Because multiple LED lines need to be controlled, the data must contain the line number to determine which line the information should go to. In actual engineering, the number of lines is generally several or more than a dozen.

[0018] 2.RGB data: each LED color pixel on the special-shaped screen contains three colors of red, green, and blue (R, G, B), and each color is divided into 256 according to its gray level, that is, 0-255, so , Through the color mixing of RGB three...

Embodiment 2

[0028] Embodiment 2: The LED matrix display screen is displayed by X-Y addressing mode, and its reading video data follows the rule of reading by row or by column.

[0029] LED special-shaped display screen refers to a special-shaped LED display screen, and its shape, size and dimension can be customized according to user requirements. When extracting video data, since the special-shaped screen lines are not regularly arranged in rows or columns, the direction of the lines is designed according to the actual application environment. The pixels on each line are arranged sequentially. At a certain moment, the pixel RGB data of the line goes from one end of the line to the other end through the serial port of the display control system. The data must be arranged in sequence according to the position of the pixels in the line. Therefore, Completely different from the traditional LED matrix screen, the pixel data corresponding to the video file must be extracted according to the sp...

Abstract

The invention relates to a path planning method for an LED special-shaped screen, which comprises three steps that firstly, two layers of coordinates are set for two pixel points; secondly, specific scanning is performed on each path; and thirdly, processing is performed on intersected paths. According to the invention, path planning is performed through extraction for pixels, and data of corresponding pixel points in the video can be extracted according to the line direction of the special-shaped screen, thereby facilitating data extraction in the LED special-shaped screen, and breaking through limitations of data extraction in the traditional LED display screen.

Description

technical field [0001] The invention relates to data extraction in LED display screens, and is a path planning method for LED special-shaped screens. Background technique [0002] At present, LED display screens are widely used. There are many kinds of LED display control systems and supporting systems on the market. The first control method is to use video decoding to obtain video data, and the data is completely in the form of the original video file. Arrangement, the second control method is developed and designed according to the characteristics of LED matrix display. The data output by the two control methods cannot be arranged randomly according to the special requirements of LED special-shaped screens, and are only suitable for LED rectangular dot matrix displays. Moreover, when using a video card for video processing, the video card must also be connected to a PC, and offline control cannot be realized, which limits the application occasions of the LED display. The...
