Embodiment 1

[0037] Such as figure 1 As shown, the hardware includes three parts: a PC, a mobile control platform, and a display screen. In the PC, the content to be displayed is converted into a digital signal. The mobile control platform is mainly responsible for receiving data from the PC software, adding control characters and saving it. At the same time, the mobile control platform can also send specific control commands to the display screen, switch the display content, and change the display effect. The display part mainly uses the motor to control the speed and the single-chip microcomputer to control the LED to display text, graphics or animation.

[0038] The mobile control platform is mainly responsible for receiving digital signals transmitted from the PC, adding control commands and saving them, and adopts a unique design to ensure that data will not be lost due to power failure. When it needs to be displayed, the data can be called out and wirelessly transmitted to the display s...

Embodiment 2

[0081] Using the display system of the present invention, when the distance between the PC and the display screen part is relatively short, the hardware does not need to use a mobile control platform, and the data transmission between the PC and the display screen part is realized by wire. In this embodiment, the serial port of the PC is wiredly connected to the control circuit of the single-chip microcomputer in the display part, and the display part receives data from the PC in a wired manner, and the display content or display mode can be changed on the display by operating in the PC. . The rest is the same as the first embodiment.

Abstract

The display system for persistence of vision includes PC, mobile control platform and display screen device. The display method includes converting the text or graph to be displayed into digital signal in the PC; transmitting the digital signal in wired or wireless mode to the display screen device and controlling the LEDs' on-off state with the monolithic computer in the display screen device; and driving the LED line to rotate or oscillate with the driving mechanism so as to form annular or planar display screen smartly by means of the vision persistence of human eyes. The present invention has the features of simple structure, unique visual angle, novel design, convenient use, etc. and has display content changeable at will.

Description

Technical field [0001] The invention relates to an electronic display screen, in particular to a display screen that uses the persistence effect of human eyes to generate continuous vision on discontinuous light. Background technique [0002] As a new type of display material, LED dot matrix has developed rapidly in recent years and has a good market prospect. Among them, LED large-screen displays are widely used in industries, transportation, commercial advertising, news releases, sports games, electronic scene simulation and other fields. However, the existing large LED screen requires a large number of LEDs and driver chips, and the control is complicated, which makes the display expensive and difficult to operate. [0003] The Chinese utility model with patent number 03257185.2 discloses a "multi-layer array light source mobile imaging display device", which is characterized by installing electronic control circuits on a displaceable bracket and setting it in the normal direc...
