Visual persistence motion display screen conducted by liquid metal

Abstract

The invention discloses a liquid metal conduction visual persistence motion display screen which comprises an annular structure, a plurality of straight rods arranged on the annular structure, lamp strips arranged on the straight rods, a power unit connected with the annular structure and a control and power supply circuit connected with the annular structure and the power unit. The annular structure is provided with a connecting structure, the control and power supply circuit is provided with a connecting port, the connecting structure is electrically connected with the connecting port, and the contact surface of the connecting structure and the connecting port is coated with liquid metal. The liquid metal is coated on the contact surface of the connecting structure and the connecting port, so that the transmission of electric energy and electric signals is met, the situation of unstable connection caused by heating and temperature rise of the annular structure in a high-speed rotating state is avoided, the stability of electrical connection is improved, and the situation that the visual effect is influenced due to disconnection is avoided.

Description

technical field [0001] The invention relates to the technical field of LED motion display screens, in particular to a motion display screen with persistence of vision conducted by liquid metal. Background technique [0002] When the human eye observes the scene, the light signal is transmitted to the brain nerve, and it takes a short period of time. After the effect of light is over, the visual image does not disappear immediately. This residual vision is called "after image". This phenomenon of vision It is called "persistence of vision". At present, the sports display screens on the market are based on the principle of visual persistence. When the light strip is moving at a high speed, it can quickly switch the LED light bead on and off, as well as parameters such as color temperature and light intensity, so as to display the display on the naked eye. The specified screen can be used as a display screen. Commonly used sports display screens include rotary sports display ...

AI Technical Summary

Problems solved by technology

Because the center position of the rotating body is the setting position of the motor, a non-luminous black spot will be left in the center of the screen when rotating, which will affect the overall display effect

If the bias power method is adopted, there is a problem that the connection effect between the light bar and the power supply and control circuit is unstable
