Combined display unit of energy-saving and innovative light-emitting diode (LED) display screen

Abstract

The invention relates to a combined display unit of an energy-saving and innovative light-emitting diode (LED) display screen,. The combined display unit comprisinges a module mounting strip combination unit, LED display modules, a first electrical box and a lower frame, wherein the module mounting strip combination unit is formed by N module mounting strips which are parallel to one another and are arranged vertically; the LED display modules are arranged at the front sides of the module mounting strips; the first electrical box is arranged at the upper side of the module mounting strip combination unit and is also used as an upper frame; the lower frame is positioned at the lower side of the module mounting strip combination unit; the first electrical box is internally provided with alternating current (AC) / direct current (DC) conversion power supplies and a signal receiving system. In order to solve the problem of difficult power configuration of a high-power combined display unit, the lower frame of the combined display unit is also used as a second electrical box, and the second electrical box is provided with AC / DC conversion power supplies; aiming at a low-power combined display unit, the lower frame is a simple type lower frame. Compared with the prior art, the combined display unit is modularized, and can normally work only by ventilating a screen body or installing a ventilation device without being cooled by an air conditioner. The combined display unit of the energy-saving and innovative LED display screen has the advantages of being light in weight, low in cost, high in accuracy, easy to manufacture as well as simple and attractive in appearance, and increases manufacturing efficiency and installation efficiency.

Description

technical field [0001] The invention relates to the field of LED display terminals, in particular to a combined display unit of an energy-saving and innovative LED display screen. Background technique [0002] With the continuous progress of the society and the rapid development of the economy, urban construction has entered a new era of development.

AI Technical Summary

Problems solved by technology

However, there are still the following disadvantages: one is that the process requirements for long-strip LED display modules are relatively high when they are installed on site, and the efficiency of on-site construction is not high; the other is that LED displays are made to order. The length of the bar-shaped LED display module is along with the standardization of the LED display, which is not suitable for automatic assembly line operations, and the production efficiency of the factory is not high; the third is that the AC / DC conversion power supply and signal receiving system on the LED display is a kind of The independent shell located on the back side of the screen cannot be connected to the LED display module in the factory, which increases the difficulty of on-site installation
