Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] The present invention is composed of a real-time multi-screen dynamic image controller 1 and a synchronous control display unit 2 (the present invention may have multiple synchronous control display units according to actual needs).

[0029] Multi-screen dynamic image real-time controller 1 receives external video signals of different formats (including high-definition / VGA / video signals) and superimposes them into one digital image signal in real time, and simultaneously transmits multiple synchronous control display units (different synchronous control display units) through the digital image transmission bus The composition and working principle of the unit are the same, and one of them will be selected below to explain). The synchronization control display unit 2 includes an image block capture unit 21 , a synchronization adjustment unit 22 , and an image coding o...

Abstract

The invention relates to a method and a device for simultaneously displaying multiple images in real time on a full color LED dot matrix. The method of the invention comprises the following steps: a multi-image dynamic image real-time control unit superposes external video signals with different formats (high definition/VGA/video signals) into one digital image signal in real time; the multi-image dynamic image real-time control unit receives the externally input video signals, completes superposing processing in real time, synthesizes one digital image signal and simultaneously transmits the digital image signal to different synchronization control display units through digital image transmission buses; the digital image signal superposed in real time is simultaneously transmitted to a plurality of the synchronization control display units through the digital image transmission buses; and complete synchronization of digital image signals output by the different synchronization control display units is realized by image block capturing, image synchronization adjusting and image coding output.

Description

technical field [0001] The invention is applied to simultaneously display multiple different real-time multi-picture signals on a full-color LED dot matrix supported by multiple sending cards. Background technique [0002] The price of full-color LED display keeps dropping, and the direct pitch of the dot matrix is ​​denser, from the original P12 to P6, P4. With the shrinking of the LED dot pitch, the number of LED dot matrix required for display per unit area is increasing. The larger the LED display, whether indoor or outdoor, is developing in the direction of ultra-long, ultra-wide, and ultra-large dot matrix. The LED display screen composed of small dot matrix boxes is gradually developing towards 2048×1536 or even higher dot matrix. , the horizontal dot matrix is ​​as high as 10000 points, and the vertical dot matrix is ​​also greater than 1536 dots. The display of LED full-color screen is mainly composed of four parts: LED display screen, sending card, several receivi...
