Abstract

The invention discloses a radiation protection LED (light emitting diode) panel, which comprises a display unit, a control unit and a power supply unit, wherein the display unit comprises a box body and modules, the box body is provided with a plurality of modules, each module comprises a PCB (printed circuit board), an LED lamp and a driving chip, the control unit comprises a receiving card, a sending card and a controller, and the power supply unit comprises an AC / DC power supply arranged in the box body and a power supply cascade wire. The PCB comprises multiple layers which are sequentially arranged. The multiple layers of the PCB are two component layers, a power supply layer, at least one ground layer and at least one wiring layer, wherein the obverse side and the reverse side of the PCB are the component layers, the ground layer is below the obverse side and / or the reverse side of the PCB, the wiring layer is arranged between the power supply layer and the ground layer or is arranged between the ground layers. The PCB is provided with the independent and integral ground layer, thereby being capable of playing an effect of absorbing signal clutter, preventing electromagnetic radiation from spreading around, and avoiding influences imposed on operations of electronic equipment around.

Description

technical field [0001] The invention belongs to the application field of LED display screens, and in particular relates to a radiation-proof LED display screen. Background technique [0002] In the rapid development of today's modern information society, large-screen display has penetrated from commercial applications such as public information display to consumer multimedia applications. With the development of broadband networks, digital multimedia content will occupy the mainstream in the information world, and new large-screen display devices will replace traditional TV sets as the center for people to enjoy information and multimedia content. [0003] LED display (LED panel): LED is light emitting diode, the English abbreviation of light-emitting diode, referred to as LED. It is a display method by controlling semiconductor light-emitting diodes. Its general appearance is composed of many light-emitting diodes, usually red, and characters are displayed by turning on an...
