Detailed Description

The following description of the embodiments of the present application is provided by way of specific examples, and other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein. The present application is capable of other and different embodiments and its several details are capable of modifications and/or changes in various respects, all without departing from the spirit of the present application. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings so that those skilled in the art to which the present application pertains can easily carry out the present application. The present application may be embodied in many different forms and is not limited to the embodiments described herein.

In order to clearly explain the present application, components that are not related to the description are omitted, and the same reference numerals are given to the same or similar components throughout the specification.

Throughout the specification, when a component is referred to as being "connected" to another component, this includes not only the case of being "directly connected" but also the case of being "indirectly connected" with another element interposed therebetween. In addition, when a component is referred to as "including" a certain constituent element, unless otherwise stated, it means that the component may include other constituent elements, without excluding other constituent elements.

When an element is referred to as being "on" another element, it can be directly on the other element, or intervening elements may also be present. When a component is referred to as being "directly on" another component, there are no intervening components present.

The existing LED product signal transmission adopts network cable transmission, the point distance is smaller and smaller along with the technical development, the number of wires for signal transmission is more and more due to the limitation of network cable transmission bandwidth, and the increase of the number of network cables not only increases the difficulty of engineering wiring, but also affects the attractiveness of the back of the box body. And the scheme of partially adopting built-in wiring increases the operation steps and the disassembly and assembly time.

For example, the existing LED display screen uses a gigabit cable to transmit signals. The maximum data volume that one gigabit network cable can transmit is 1000000000/60/24 ≈ 690000, that is to say, the maximum number of LED pixels that can be loaded on each network cable is 690000, and the maximum number of pixels loaded on each network cable is about 600000 except data volumes of other synchronization signals and the like. Data exceeding this value requires an increase in the number of transmission network lines. The LED display screen with the higher utilization rate in the market and the box size of 600mm 337.5mm is taken as an example. The number of pixels of each box is equal to the number of longitudinal pixels and the number of transverse pixels is equal to (box width/dot pitch) × (box height/dot pitch) ═(600/1.25) × (337.5/1.25) ═ 129600, and each screen can be loaded with 600000/129600 and approximately equal to 4 boxes at most according to the calculation of 600000 pixels loaded with each screen. Taking the box with the pitch of P0.9 as an example, the number of the pixels of each box is 230400, and the number of the boxes that can be loaded by each network cable is two.

Therefore, along with the reduction of the dot pitch of the small-pitch LED display screen, the data bearing capacity of a single box body can be increased, and the box body loading quantity of a single network cable can be reduced. Ultimately resulting in an increase in the number of transmission cables from the cabinet to the screen controller. The method of using the network cable to transmit signals is not suitable for the future ultra-small-space LED display screen. It is desirable to use a transmission scheme that can transmit a larger amount of data while reducing the use of transmission cables.

Therefore, the LED box body and the LED display screen system using the same are provided for solving the problem that the LED screen body needs a large number of network cables to transmit signals in the existing scheme. Briefly, this application changes to wireless transmission, reforms transform LED screen controller (sending card) and LED box through needs, and wireless output need be supported to LED screen controller's data output mouth, and wireless input needs be supported to the data input mouth of LED box to use wireless signal to carry out data transmission's LED screen controller (sending card) and use wireless signal to carry out signal transmission's LED box.
