Problems solved by technology

[0003] In the prior art, LED display screens generally adopt the form of a box body, and various drive unit modules, power supplies, fans, etc. are fixed in the box body. Modules, power supplies, fans, and other electronic components are all fixed in the box, so the box looks cumbersome, and since the LED unit boards are integrated with the box, it is very cumbersome during movement, transportation, installation, etc., increasing the movement , transportation, installation, etc.
[0004] In addition, the existing technology also sets the LED display as a transparent LED display, which greatly reduces the weight and volume of the LED display. However, due to technical limitations, the transparent LED display is not light enough, so that the LED display can There are still some difficulties in moving, transporting and installing

Embodiment 1

[0023] like figure 1 As shown, this embodiment provides a light and thin LED display screen, the light and thin LED display screen includes two or more PCB strips, for example, including a PCB strip 101 and a PCB strip 102, each PCB strip can be fixed in a frame to form a transparent thin LED display, or each PCB strip can also be fixed on two or more beams to form a transparent thin LED display, or each PCB strip can be directly fixed on the installation On the medium, a light and thin LED display screen is formed, and each formed light and thin LED display screen can be used to display text, graphics, letters and animations.

[0024] Two or more LED units 103 are arranged on each PCB strip. like figure 2 As shown, each LED unit includes two or more LED thin-film chips stacked on each other and a package body 203 .

[0025] Each LED thin film chip 204 is sealed and fixed in the package body 203, for example, sealed and fixed, or semi-sealed and fixed; and, by setting two ...

Embodiment 2

[0041] On the basis of the above examples, in the light and thin LED display screen provided by this embodiment, the LED thin film chip may be a color thin film chip including a red thin film chip, a green thin film chip and a blue thin film chip, or any two color thin film chips. In addition, the thin-film chips of the same color are LED thin-film chips of the same or adjacent wavelengths, so that the light and thin LED display screen of this embodiment can be displayed uniformly, and the display Works well.

[0042] Preferably, a red thin film chip, a green thin film chip and a blue thin film chip can be set in the light and thin LED display screen at the same time, including three colors of LED thin film chips, which can form any color that exists in nature, that is, a full Color light and thin LED display, according to the requirements of various occasions, as well as the type and brightness of each color thin film chip, the number ratio of red thin film chips, green thin ...

Embodiment 3

[0044] On the basis of the above examples, in the light and thin LED display screen described in this embodiment, one or more support bars are further provided, and each support bar is used to reinforce the light and thin LED display screen.

[0045] For example, one or more support bars are arranged between the first PCB bar and the second PCB bar, one end of any support bar is fixedly connected to the support body on the first PCB bar, and the other end of the support bar is connected to the support body on the first PCB bar. The support body of the second PCB strip is fixedly connected, so that the first PCB strip and the second PCB strip are relatively fixed, so that the light and thin LED display screen is more stable.

[0046] The material of each of the support bars can be set to be metal, rigid plastic, etc., to support, fix, and shape the light and thin LED display screen.

[0047] In addition, each support bar and its corresponding support body may be integrally inje...
