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.

Embodiment 1

[0023] Such as figure 1 As shown, the present embodiment provides an LED display screen 101, and the LED display screen 101 includes two or more installation strips, one or more power lines, one or more signal lines and several LED lighting units; for example, includes There are two installation strips 102a, 102b, one power supply positive line, one power supply negative line, one signal line and several LED lighting units 104 .

[0024] The mounting strips can be arranged parallel to each other or vertically, and are fixed to each other at intersections.

[0025] It can also be integrally formed, and on this basis, several reinforcing ribs are set.

[0026] Each installation bar is used for installing each LED light-emitting unit 104, thus constitutes the LED display screen 101 of this embodiment; Building walls, installation panels, etc., are installed and fixed by installing and fixing each installation strip, thereby forming a stable LED display screen. By installing ea...

Embodiment 2

[0052] Such as figure 2 As shown, on the basis of the above examples, the side of the installation position is provided with a power line interface and a signal line interface, wherein the power line interface may include a power supply positive line interface and a power supply negative line interface; the signal line interface It includes a signal line input interface and an output interface; and, the power supply positive line interface is fixedly electrically connected to the power supply positive line 201, the power supply negative line interface is fixedly electrically connected to the power supply negative line 203, and the signal line input interface and output interface They are fixedly connected to signal lines 202 respectively.

[0053] Each power line interface and each signal line interface are used to electrically connect the correspondingly installed LED light emitting unit 104 with the positive power line 201 and the negative power line 203 when installing eac...

Embodiment 3

[0066] On the basis of the above examples, any LED lighting unit includes one or more LED chips and its control module, the control module is connected to each signal line signal, and the LED control signal is input through the signal line input interface , to control each LED chip to emit light, so that the LED display screen composed of each LED light-emitting unit can display various graphics, text, letters and animations.

[0067] Moreover, each LED chip and its control module are integrated and packaged; that is, each LED chip and the control module are placed in the same package shell, and the package shell has a certain degree of waterproof, dustproof, and electric shock protection for each LED chip and the control module. Protective function; each LED chip includes one of red LED chips, green LED chips and blue LED chips, or any two of them, or three of them; the control module can be fixedly electrically connected to each LED chip, It can also be integrally formed. Fo...

Abstract

The invention disclose an LED display screen comprising at least two installation bars, at least one power circuit, at least one signal circuit and a plurality of LED luminous units. The minimum distance among the installation bars is 5cm; correspondingly to the each LED luminous unit, the each installation bar is provided with at least one installation position for correspondingly installing andfixing the each LED luminous unit; the minimum distance among the each installation position is 5 cm; and any one of the LED luminous units comprises at least one of LED light-emitting diodes with atleast one color, and the each LED light-emitting diode with the same color is the LED light-emitting diode of the same sorting file and the adjoining sorting files thereof. The LED display screen hashigh transparency, good heat dissipation effect and strong wind resistance, and convenient and flexible assembling and disassembling.

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-...
