Problems solved by technology

Since the luminous pixels of the display screen are all set on an opaque planar structure, the application of the display screen in some occasions is limited or cannot play a better effect
For example, installing a large-area conventional LED display outside or inside the glass curtain wall of a building will seriously affect the lighting inside the building and the visual range of people in the building, or affect the visual range viewed from the outside of the building.
[0004] Alternatively, there are also LED displays in which the LED display is set to be transparent, which greatly improves the transparency and heat dissipation of the opaque flat plate structure, but the distance between each pixel of the LED display is still set according to the traditional method. The transparency of the display screen is still not high enough, it still affects part of the visual range of people in the building, and it is difficult to withstand huge temperature differences and hurricanes

Embodiment 1

[0024] like figure 1 As shown, this embodiment provides an LED display screen 101 , and the LED display screen 101 includes one panel or multiple panels, and several LED lighting units 103 .

[0025] Wherein, the panel is set as a grid-shaped PCB panel, that is, it is integrally formed by mutually perpendicular horizontal PCB strips 102 and vertical PCB strips 104; The constituent elements are square holes; the distance between two adjacent horizontal PCB strips is 5 cm to 500 cm; or, the distance between two adjacent vertical PCB strips is 5 cm to 500 cm; or, the adjacent The distance between two horizontal PCB strips is 5 cm to 500 cm, and the distance between two adjacent vertical PCB strips is also 5 cm to 500 cm.

[0026] For example, for each horizontal PCB strip, the spacing between adjacent horizontal PCB strips is the same, and for each vertical PCB strip, the spacing between adjacent vertical PCB strips is the same.

[0027] For example, set a defined range that in...

Embodiment 2

[0047] On the basis of the above examples, the distance between two adjacent horizontal PCB strips can be set to 10 cm to 300 cm; or, the distance between two adjacent vertical PCB strips can be set to 10 cm to 300 cm; Alternatively, the distance between two adjacent horizontal PCB strips and the distance between two adjacent vertical PCB strips can both be set to 10 cm to 300 cm.

[0048] Therefore, there is a minimum of 10 cm x 10 cm = 100 square centimeters between each PCB strip, and a maximum of 300 cm x 300 cm = 90,000 square centimeters of space, compared to setting the spacing between adjacent PCB strips to 5 cm to 500 cm, the space between the PCB strips is more rationalized, so that the distance of the LED display screen can be optimized within the scope of not affecting human vision.

[0049] Further, the space between the PCB strips is more rationalized, so that the LED display screen can be used without affecting the visual range of the people in the building, and...

Embodiment 3

[0051] like figure 2 As shown, on the basis of the above examples, one or more rigid support bars 201 are provided on each horizontal PCB strip 102 , or one or more rigid support bars 202 are also provided on each vertical PCB strip 104 .

[0052] Wherein, the rigid support bar 201 and the rigid support bar 202 are made of rigid materials, have good strength, and can support and bear the weight of each horizontal PCB bar 102 and vertical PCB bar 104, so that the The installation of the PCB panel is more stable. For example, the rigid support bar 201 and the rigid support bar 202 are made of rigid metal material, or the rigid support bar 201 and the rigid support bar 202 are made of hard resin material.

[0053] Each rigid support bar can be integrally formed with the horizontal PCB bar 102 and the vertical PCB bar 104, or can be fixed on the horizontal PCB bar 102 or the vertical PCB bar 104 by a fixing device, for example, can be fixed by fixing screws, rivets, latches, buck...

Abstract

The invention discloses an LED display screen, comprising at least a panel and a plurality of LED light-emitting units, wherein, the panel is a gridding PCB panel and is integrally formed by horizontal PCB bars and vertical PCB bars, which are vertical to each other; the space between two adjacent horizontal PCB bars or vertical PCB bars is 5cm to 500cm; corresponding to each LED light-emitting unit, an installation position is arranged on the surface of the horizontal PCB bar or vertical PCB bar and is used for correspondingly installing and fixing each LED light-emitting unit. The LED display screen is high in transparency, good in heat dissipation effect, strong in wind resistance and convenient and flexible in assembly and disassembly.

Description

technical field [0001] The invention relates to an LED illuminating device, in particular to an LED display screen. Background technique [0002] LED has been widely valued for its high luminous efficiency, long service life, safety, reliability, environmental protection and energy saving. As an important means of information dissemination, LED display has become a symbol of urban information modernization. With the continuous progress of social economy and the continuous improvement of LED display technology, people's understanding of LED display will become more and more in-depth. , and its application fields will become wider and wider. [0003] In the prior art, the LED display screen is generally on an opaque flat plate structure, and a pixel is composed of light-emitting diodes or LEDs, and each pixel is arranged in a matrix at a certain interval to form a unit board with patterns and text information, which is controlled by a control device. , so as to display rich-...
