Embodiment Construction
[0027] In order to further illustrate the technical means adopted by the present invention and its effects, the following is a detailed description in conjunction with preferred embodiments of the present invention.
[0028] A method for implementing vertical placement of light strip tubes, which is based on an LED display control system, the tube is a light bar interface, and the LED display control system includes an upper PC, a sending card, a receiving card and LED display, according to the LED display light bar wiring way, set the configuration information in the control software of the upper PC, and send the serial port command to the sending card through the serial port; the sending card is connected to the video source to receive its video data, and The serial port command and video data are packaged into network packets, the receiving card analyzes the data of the network packets, generates relevant configuration parameters, generates driving waveforms, and outputs the...

The invention provides a handling and implementing method for vertical placing of a line pipe of a lamp strip. The handling and implementing method specifically comprises the following steps that S11, frames of video data is cut and partitioned by a receiving card according to the loading height of each group of data of an actual LED module, so that the video frame position carried by each group of data is determined; S12, a lamp panel scanning number and a line breaking number are input into a formula 1 to calculate a storage address for storing; and S13, the cache data is read according to an address reading formula, so that the lamp strip with the line pipe being vertically placed is converted to a conventional lamp panel for hardware circuit scanning. According to the handling and implementing method, the loading area of the receiving card is increased, so that the number of the receiving card used by an LED large screen is greatly reduced, and hardware cost can be obviously lowered; the number of introduced empty points can be effectively reduced, and the maximum refresh rate of an LED screen is improved; a controlling software of an upper PC machine is universal so that different kinds of lamp panels can be flexibly supported, development time and development difficulty of the program of the controlling system are reduced; and meanwhile, the time for delivering to customers is greatly shortened for an LED screen factory.
Description
technical field [0001] The present invention relates to the technical field of LED display, in particular to a method for realizing the vertical placement of lamp strip tubes. Background technique [0002] LED screens are widely used in practice because of their flexible splicing of LED modules, arbitrary size, high brightness, wide visibility, and convenient disassembly and maintenance. A new type of LED screen: In order to increase the light transmittance, the light board is made into a light bar, that is, the light bar is placed vertically by the line tube, and the line tube is the light bar interface. This kind of light bar is very different from the hardware circuit scanning method of conventional light boards. [0003] As the core and soul of the LED display screen - LED control system, whether it can support and process this kind of special driving light board, and which processing method is adopted will directly determine whether the light board can display and play...
