Problems solved by technology

[0004] However, as people become more familiar with the use of LED display systems and pursue display effects, more and more large-scale display data such as pictures are added to the display data. getting bigger and bigger, and the communication time is getting longer and longer
However, due to the need to control the hardware cost at a relatively low level, the memory capacity of the small LED display system is usually very small, so when the LED display system using the existing data transmission method transmits a large amount of display data, the transmission speed and usage The performance will be significantly reduced, which will greatly affect the market competitiveness of the LED display system

Embodiment Construction

[0040] The present invention will be further described in detail below through specific embodiments and accompanying drawings.

[0041] The core technical solution of the data transmission processing method described in the present invention is: adopt compression technology to compress the data, and make adaptive processing at both ends of the communication, that is: compress the data at the data sending end, and compare the size of the compressed data and the original data , if the compressed data is smaller than the original data, the compressed data is sent, otherwise the original data is sent; at the data receiving end, the received original data is directly stored, and the received compressed data is first decompressed and then stored.

[0042]The compression rate of the compression algorithm depends on the correlation of the data before and after, so the data after the data sender performs compression processing cannot fully guarantee the reduction of the data volume. In...

Abstract

The invention discloses a data transmission processing method and system. The method comprises: A, data is compressed at a data transmitting terminal, the size of the compressed data is compared with the size of the original data, if the size of the compressed data is less than that of the original data, the compressed data is sent, otherwise the original data is sent; and B, at a data receiving terminal, the received original data is directly stored, and the received compressed data is decompressed and then stored. The system comprises the data transmitting terminal and the data receiving terminal, wherein the transmitting terminal is used for executing the step A, and the receiving terminal is used for executing the step B. The invention also discloses a light-emitting diode (LED) display system, comprising a display control module, an LED control panel, a memorizer and an LED display screen, wherein the display control module is taken as the data transmitting terminal in the methoddisclosed by the invention, and the LED control panel is taken as the data receiving terminal in the method disclosed by the invention. According to the invention, the transmission speed for displaying data in a low-cost display system and the operational performance can be improved.

Description

technical field [0001] The present invention relates to the technical field of electronic display data transmission processing, in particular to a data transmission processing method, system and a light emitting diode (LED, Light Emitting Diode) display system applying the data transmission processing method. Background technique [0002] The LED display screen is also called an electronic display screen or a floating word screen. Its principle is to display information such as text, pictures, animations, and videos through the dimming of LED dot matrix lamp beads. LED display has the characteristics of high brightness, uniform luminescence, low power consumption, long life, strong weather resistance, and good reliability. Information display fields such as public display screens. [0003] At present, the usual structural components of small LED display systems used in the industry include: display control equipment such as computers, LED control boards and LED display scre...
