Abstract

The invention discloses a light emitting diode (LED) assembled screen. The LED assembled screen comprises a control box, a framework and at least two LED display modules, wherein the control box at least comprises two independent paths of output interfaces; each output interface is connected with one LED display module; the at least two LED display modules are assembled and fixed on the framework; each of the LED display modules comprises a box body, a circuit board, a pouring sealant, a driving chip, an input interface and a plurality of LED chips; the driving chip and the plurality of are arranged on the circuit board; the driving chip is connected with the LED chips and the input interface respectively; the input interface is formed on the box body and connected with the corresponding output interface of the control box; the box body has a flat structure, and one face of the box body is provided with an opening; the circuit board is arranged in the box body; the pouring sealant is covered on the circuit board so as to seal the opening face of the box body; and the LED chips are arranged on one side, corresponding to the opening face of the box body, of the circuit board. Due tothe LED assembled screen, the assembling flexibility of an LED display screen is improved, and the LED assembled screen is convenient to install and maintain.

Description

technical field [0001] The invention relates to the field of LED display technology, in particular to an LED assembly screen. Background technique [0002] The LED electronic assembly screen currently used can display large-scale advertising patterns, advertisements, and promotional terms, and can control the LED to display different advertisements or changing colors through the circuit board, which is conducive to attracting consumers' attention, so it is very popular among users. . [0003] Existing LED displays include conventional displays and strip screens, among which: [0004] 1) Conventional display screens, including thick and heavy boxes, are large in size and heavy in weight, require high installation carriers, and take up a large maintenance space. In addition, installation and maintenance costs are high. [0005] 2) The screen is directly connected to the control box using a strip LED light bar, with a through hole connection in the middle, and the connection ...
