Abstract

The invention discloses a receiving card, a data storage scheduling method and an LED display control system, comprising a control module, a receiving card memory and a receiving card microprocessor respectively connected with the control module, and a receiving card nonvolatile memory connected with the receiving card microprocessor. The control module is used for identifying and parsing the local data packet and executing the control instruction of the receiving card. The four Banks in the memory of the receiving card are divided into two Bank video streams, a correction coefficient channelcontaining one Bank and an online upgrade data channel containing one Bank , which are respectively used for storing the video data, the correction coefficient and the online upgrade data obtained byparsing. The receiver card microprocessor is used to realize the online upgrade of the system. The receiving card nonvolatile memory is used to cure the correction factor. The invention can realize video data processing, white balance correction, on-line upgrading and intelligent setting in the limited bandwidth, and improve the stability, flexibility and reliability of the display control.

Description

technical field [0001] The invention belongs to the technical field of LED display control, and more specifically relates to a receiving card, a data storage scheduling method and an LED display control system. Background technique [0002] As an important medium for modern information release, the full-color LED large screen adopts nonlinear correction technology, which has the characteristics of clearer image, stronger layering, no reflection and suitable for viewing from multiple angles. It is widely used in industry, transportation, commerce, advertising , finance, sports competitions, simulated military exercises, electronic landscapes and other fields. The current LED lamp bead production and manufacturing technology is not perfect. Due to the deviation of the manufacturing process and packaging problems, even for LED lamp beads produced in the same batch, there may still be considerable differences in the luminous intensity and dominant wavelength between individuals,...
