Dynamic imaging device of LED lampstandards and application of same in tunnel advertisements

Abstract

The invention discloses a dynamic imaging device for an LED lamppost, which consists of a plurality of LED lamps arranged to form an LED lamppost, and a plurality of LED lampposts form an array as a display device; a PC controls the main control module of the display device through a network, wherein the main control The module has an information storage function, and the PC can replace its stored information through the network. The main control module realizes the asynchronous display function with the PC; the main controller inputs the signal to the scanning control module to scan the image, and the display driver module drives the LED lamp post Make it display information; the main control module is connected to the synchronous control module for generating a synchronous clock, so that the main control and the LED lamp post display device keep scanning synchronously; multiple LED lamp post arrays keep scanning synchronously, so that regardless of the observer The display of the complete picture can be realized whenever the picture is observed. The present invention can be directly applied to related animation display of subways and railway tunnels, to roller advertising display devices and various dynamic display devices, and to various toys and decorations with dynamic display functions.

Description

technical field [0001] The invention relates to a dynamic imaging technology based on the principle of visual persistence and motion imaging, in particular to a dynamic imaging device for LED lampposts and its application in tunnel advertisements. Background technique [0002] Along with the development of LED technology, the display technology composed of LED dot matrix has been vigorously developed accordingly. Due to the advantages of high brightness, low power consumption, and large size of LED display technology, it has been widely used in advertising display. [0003] In the existing technology, the dynamic imaging technology is relatively mature. For example, the dynamic imaging technology used in tunnel advertising mainly includes the following types: [0004] First, install a projector on the train carriage, and directly project the picture on the tunnel wall. Technical features: clear picture, good synchronization, playback speed has nothing to do with vehicle s...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to overcome the problems of high operating cost of the existing dynamic imaging technology, inconvenient information replacement of advertising light boxes, poor synchronization of electronic display screens and monotonous colors, and provide a Dynamic imaging device for LED lampposts
