Abstract

The invention discloses an LED display screen with moisture-proof and dust-proof functions, which comprises: an electronic display module, which is provided with an LED light-emitting array and vent holes arranged in an array, and the vent holes are formed on the electronic display module a hollow structure to allow airflow to pass through the electronic display module; a transparent plate; a box shell, which includes a front shell and a rear shell, and the electronic display module separates the box shell to form a first cavity and a second cavity, the second A cavity communicates with the second cavity through an air flow hole; a moisture-proof, dust-proof and cooling system, which realizes rapid moisture-proof, dust-proof and cooling of the system through an air heating device and a gas driving device. The display screen of the invention has the characteristics of high heat dissipation efficiency, moisture-proof and dust-proof, and the like.

Description

technical field [0001] The invention relates to the technical field of electronic display screens, in particular to an LED display screen with moisture-proof and dust-proof functions. Background technique [0002] LED is a solid-state semiconductor device that can directly convert electrical energy into light energy. Like traditional light sources, LEDs also generate a lot of heat during operation. LED has the advantages of energy saving, long service life, and no heavy metal mercury inside, so that LED is widely used in life. The electronic display screen prepared with LED as the light source can be used to display text, graphics, images, animations, market prices, video, video signals and other information display screens. LED display screens can be used not only in indoor environments, but also in indoor environments, with a wide range of uses. In a humid environment, if the LED display is not subjected to moisture-proof treatment, it will affect the normal operation o...
