Abstract

The invention relates to an electronic display unit. The electronic display unit comprises an electronic display module and also comprises a heat dissipation supporting plate, a frame strip, a vertical supporting strip, a horizontal supporting strip as well as a first connector, a second connector and a third connector for improving heat dissipation effect, wherein the frame strip is arranged at the rear side of the heat dissipation supporting plate; the first connector, the second connector and the third connector are fixedly arranged at the rear side of the heat dissipation supporting plate and used for fixing the frame strip, the vertical supporting strip and the horizontal supporting strip; a heat conducting block on the display module is arranged at the rear side of the electronic display module, and the electronic display module is arranged at the front side of the heat dissipation supporting plate in an array, so that the heat conducting block on the display module clings to the front side surface of the heat dissipation supporting plate. According to the technical scheme, an electronic display screen composed of the electronic display unit provided by the invention can achieve good heat dissipation effect by only keeping the rear side of a screen body ventilative; and the electronic display unit has the advantages of simple structure, convenience in mounting, good heat dissipation and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of electronic information display, in particular to an electronic display unit. Background technique [0002] Electronic display screens have been widely used in various public places indoors and outdoors. As we all know, electronic display screens are composed of large-scale light-emitting devices, integrated circuits and peripheral electronic components; waterproof specifications and heat dissipation conditions are key technical elements of outdoor electronic display screens. At present, most of the electronic display units used in outdoor electronic display screens adopt a box-type structure, and then the electronic display units are assembled into a display screen body in arrays. In order to meet the outdoor waterproof requirements, a fully enclosed outer box is formed around and on the back of the screen of the electronic display; Usually, the refrigeration and air conditioner is installed in a closed screen bo...
