Problems solved by technology

[0002] The existing double-sided LED display usually splices two conventional single-sided LED display units back-to-back so that the display surfaces of the two LED display units face opposite directions to realize the double-sided display of the LED display. The cabinet of the two-sided LED display needs to install the LED display units on the opposite sides, so the thickness of the cabinet is relatively large, and the LED display is bulky as a whole, which makes it inconvenient to carry and install the LED display. Large installation space is required, which limits the application occasions of double-sided LED displays and is not conducive to the development of double-sided LED displays

Embodiment 1

[0040] Please refer to Figure 1 to Figure 4 , Embodiment 1 of the present invention is: a display screen unit for assembling a display screen, and several display screen units can be spliced ​​into a display screen with a required area.

[0041] Such as figure 1 As shown, the display screen unit includes a PCB board 1 and a power supply box 3 arranged on the PCB board 1, the power supply box 3 contains a power supply device for supplying power to the PCB board 1, and the power supply box 3 It is electrically connected with the PCB board 1, and a plurality of lamp driving integration devices 2 are respectively provided on opposite sides of the PCB board 1, and the lamp driving integration devices 2 are electrically connected with the PCB board 1 , the direction of the light output of the lamp driver integrated device 2 located on different sides of the PCB board 1 is opposite, so that the display unit can realize double-sided display without using single-sided display splicin...

Embodiment 2

[0049] Please refer to Figure 5 to Figure 7 , Embodiment 2 of the present invention is: a double-sided display screen, including at least one display unit described in Embodiment 1, which is applied to scenarios including but not limited to advertising machines, light pole screens, and all-in-one machines.

[0050] Please combine Figure 5 and Figure 6 , in this embodiment, the double-sided display screen is formed by splicing two display screen units, wherein two PCB boards 1 are arranged side by side, and the opposite sides of the PCB board 1 are respectively provided with a first mask 6 and a The second mask 7, the structure of the first mask 6 and the second mask 7 is the same as the structure of the mask described in Embodiment 1, at least one group of the first mask 6 covers the two PCB boards 1 The gap between, at least one set of the second face shield 7 covers the gap between the two PCB boards 1 from the side opposite to the first face shield 6, the first face sh...

Embodiment 3

[0054] Please refer to Figure 8 and Figure 9 , Embodiment 3 of the present invention is another technical solution proposed for the structure of PCB board 1 on the basis of Embodiment 2. The difference from Embodiment 2 is only in the structure of PCB board 1 .

[0055] Such as Figure 8 and Figure 9 As shown, in this embodiment, the light driving integrated device 2 is arranged in a matrix on the PCB board 1, and the PCB board 1 is provided with a hollowed out part 12 that runs through the PCB board 1, and the hollowed out part 12 Arranged between any two adjacent rows or two columns of the lamp driver integration device 2, further reducing the overall weight of the double-sided display screen, and at the same time, a transparent display screen can be formed by setting the hollow part 12 , to improve the display effect of the double-sided display screen, the double-sided display screen in this embodiment can also be applied in scenes such as building facades of glass cu...

Abstract

The invention discloses a display screen unit and a double-sided display screen. The display screen unit includes a PCB, the two opposite side faces of the PCB are each provided with a plurality of lamp drive integrated devices. Each of the lamp drive integrated devices comprises a drive IC, an R chip, a G chip and a B chip which are packaged into an integrated structure, the drive IC is electrically connected with the R chip, the G chip, the B chip and the PCB, and the light emitting directions of the lamp drive integrated devices located on different side faces of the PCB are opposite. According to the double-sided display screen provided by the invention, the double-sided display can be realized by using one layer of PCB; the overall thickness of the double-sided display screen is greatly reduced; and the lamp driver integrated devices are packaged into an integrated structure, so that the distance between the lamp driver integrated devices is reduced, the display effect of the double-sided display screen is improved, the double-sided display screen is lighter and thinner, the mounting space required by the double-sided display screen is reduced, the double-sided display screenis convenient to transport and mount, and the application range of the double-sided display screen is widened.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a display screen unit and a double-sided display screen with the display screen unit. Background technique [0002] The existing double-sided LED display usually splices two conventional single-sided LED display units back-to-back so that the display surfaces of the two LED display units face opposite directions to realize the double-sided display of the LED display. The cabinet of the two-sided LED display needs to install the LED display units on the opposite sides, so the thickness of the cabinet is relatively large, and the LED display is bulky as a whole, which makes it inconvenient to carry and install the LED display. Large installation space is required, which limits the application occasions of double-sided LED display screens and is not conducive to the development of double-sided LED display screens. Contents of the invention [0003] The technical problem t...
