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

Abstract

The invention discloses a dynamic imaging device of LED lampstandards. A plurality of LED lamps are arranged in order so as to form one LED lampstandard, and an array is formed by the plurality of LED lampstandards so as to play the role of a display device; and a main control module of the display device is controlled by a PC (personal computer) through a network, wherein the main control modulehas the function of storing information, the information stored in the main control module can be replaced by the PC through the network, and the main control module can achieve the function of asynchronous display with the PC; a main controller is used for inputting signals into a scanning control module so as to scan images, a display driving module is used for driving the LED lampstandards to display the information; the main control module is connected with a synchronous control module used for generating a synchronous clock so that synchronous scanning can be maintained between the main control module and the LED lampstandard display device; and the synchronous scanning is maintained among a plurality of LED lampstandard arrays so as to achieve the purpose of completely displaying pictures seen by viewers at any time. The invention can be directly applied to the display of corresponding cartoons in metros and railway tunnels, as well as to roller advertisement display devices, various dynamic display devices, and various toys and ornaments 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] 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 speed,...

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
