Problems solved by technology
The point-by-point correction data generated by the computer is generally transmitted to the LED screen through the serial port. Due to the large amount of LED point-by-point correction data, and the serial port transmission rate is low and the error rate is high, complex circuit structures and computing systems are required to ensure data. Correct, so the serial port transmission link becomes the bottleneck link of the entire LED screen point-by-point calibration process, and it takes a long time

The invention discloses a high-speed mass data transfer system and an implementation method thereof, aiming to solve the technical problem of improving the transmission speed of color correction data of a display screen and the efficiency of single-point color correction of the display screen. The system comprises a computer, a display card, a video receiver, a video transmitter and a display screen, wherein the display card is connected with the computer through a PCI bus; the display card and the computer are respectively connected with the video transmitter; the video transmitter is connected with the video receiver; and the video receiver is connected with the display screen. The implementation method comprises the following steps: data preparation, state conversion, data read-in, data transfer, data receiving, receiving conformation, judgment ending and state restoring. Compared with the prior art, the invention transmits mass point correction data into the video transmitter and the display screen by adopting a video data communication link with a bandwidth being higher than 1G, thereby greatly improving the transmission speed of the mass data and greatly improving the efficiency of the single-point color correction of the display screen.
Description
Technical field [0001] The invention relates to a data transmission system and an implementation method thereof. Background technique [0002] Due to the inconsistency of brightness and wavelength in the production of LED chips in the prior art full-color LED display, the red, green, and blue LED lights must be first classified according to brightness and chromaticity and then supplied according to different grades, thereby increasing The cost of the product. Even so, there are still some errors in the brightness and chromaticity of the red, green, and blue LED lights, causing the display to have a color difference and blurring. On the other hand, after the display has been used for a period of time, the aging of the LED tubes is inconsistent, resulting in a blurry display on the LED screen. Or uneven colors. The method to solve the appeal problem is mainly to use point-by-point color correction technology, that is, a correction system composed of a computer and a camera is use...
