Embodiment 1

[0037] As shown in Figure 1, the hardware includes three parts: PC, mobile control platform and display screen. Convert the content to be displayed into a digital signal in the PC. The mobile control platform is mainly responsible for receiving the touch data from the PC-side software, adding control characters and saving them. At the same time, the mobile control platform can also send specific control commands to the display screen to switch the display content and change the display effect. The display part is mainly to control the speed of the motor 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 the digital signals transmitted from the PC, adding control instructions and saving them. The unique design ensures that the 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 di...

Embodiment 2

[0081] Using the display system of the present invention, when the distance between the PC and the display screen is relatively short, the mobile control platform may not be selected as the hardware, and the data transmission between the PC and the display screen is realized by wire. In this embodiment, the serial port of the PC is connected to the single-chip microcomputer control circuit of the display screen by wire, and the display screen receives data from the PC by wire, and the display content or display mode can be changed on the screen by operating in the PC . All the other are the same as embodiment one.

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 which utilizes the persistence of vision effect of human eyes to generate continuous images for 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 fields such as industry, transportation, commercial advertisements, press releases, sports competitions, and electronic scene simulation. However, the existing LED large screen requires a large number of LEDs and driver chips, and the control is complicated, which makes the display screen expensive and difficult to operate. [0003] The Chinese utility model patent No. 03257185.2 discloses a "multi-layer array light source mobile imaging display device", which is characterized in that an electronic control circuit is installed on a displaceable s...
