Electronic display screen system based on remote control

Abstract

The invention relates to an electronic display system based on remote control, which is characterized in that it includes a first computer, a second computer, a communication network, a single-chip microcomputer, a clock control module, a brightness adjustment module, a keyboard input module, a memory, and a row drive module , a column drive module, a vehicle-mounted LED dot-matrix display, a communication module, and a voice unit, the first computer is connected to a second computer, the second computer is connected to a single-chip microcomputer through a communication network, and the control end of the single-chip microcomputer is respectively connected to a row drive module, Column drive module, the row drive module and the column drive module are connected to the vehicle-mounted LED dot matrix display, the single-chip microcomputer is respectively connected to the brightness adjustment module, keyboard input module, memory, and voice unit, and the brightness adjustment module is connected to the vehicle-mounted LED dot matrix display Screen. The beneficial effect of the invention is that it can be controlled remotely, and each computer can control multiple LDE display screens, which reduces the use cost and is more convenient and practical.

Description

technical field [0001] The invention relates to the technical field of electronic display screens, in particular to an electronic display screen system based on remote control. Background technique [0002] The LED display screen is divided into a graphic display screen and a video display screen, both of which are composed of LED matrix blocks. The graphic display screen can display Chinese characters, English text and graphics synchronously with the computer; the video display screen is controlled by a microcomputer, with both graphic text and images, and plays various information in a real-time, synchronous and clear information dissemination method, and can also display two Dimensional, 3D animation, video, TV, VCD programs and on-site live. There is a certain distance (generally no more than 10 meters) between the controlling computer and the LDE screen; each computer can generally only control one LDE display. All of these greatly limit the development of LED display...

AI Technical Summary

Problems solved by technology

There is a certain distance (generally no more than 10 meters) between the controlling computer and the LDE screen; each computer can generally only control one LDE display

All this greatly limits the development of LED display

It is more difficult to achieve if the user requires remote control or multiple control

In addition, since each system must be controlled by a computer, the single investment of the system is relatively large, and the maintenance and management costs are also relatively high, all of which greatly restrict the development of LDE display screens
