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] As shown in Figure 1, the present embodiment provides a light and thin LED display screen, which includes two or more PCB strips, such as PCB strips 101 and PCB strips 102, and each PCB strip can be fixed on 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 It is fixed on the installation medium to form a light and thin LED display screen, and each formed light and light LED display screen can be used to display text, graphics, letters and animations, etc.

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

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

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 can be a kind of color thin film chip including red thin film chip, green thin film chip and blue thin film chip, or any two. different color thin film chips, or include three color thin film chips; and the thin film chips of the same color are LED thin film chips of the same or adjacent wavelengths, so that the thin and light LED display screen of this embodiment can be displayed evenly and display The effect is good.

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

Embodiment 3

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

[0045] For example, one or more support bars are set 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 The supporting 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 thin and light LED display screen is more stable.

[0046] The material of each support bar can be set to be metal, hard plastic, etc., to play a role of support, fixation, shaping and other reinforcement for the thin and light LED display screen.

[0047] Moreover, each support bar and its corresponding support body can be integrally injectio...
