Problems solved by technology

However, for small-pitch LED displays, due to the high resolution and the dense division of LED light-emitting diodes, the space for fixing the mask becomes very small, so the installation and fixing of the mask is also difficult.

Embodiment 1

[0025] refer to Figure 1~6 , the fixing structure of an outdoor small-pitch LED display module mask provided by the present invention includes a bottom shell 1, an LED panel 2 fixed on the bottom shell 1, a mask 4 fastened to the LED panel 2 and a face shield for fixing the mask. 4 multiple cylinders 3 . The cylinder 3 is a stepped cylinder, including a first step 31 and a second step 32, the diameter of the first step 31 is greater than the diameter of the second step 32, wherein the first step 31 is a straight-toothed cylinder, and the end of the second step 32 is straight Tooth cylinder. Wherein, the first step of the cylinder 3 is integrally formed with the bottom case 1 through injection molding. The LED panel 2 is provided with a through hole 21 corresponding to the cylinder 3, and the mask 4 is provided with a mounting hole 41 corresponding to the cylinder 3, and a small cylinder 42 is provided on the back thereof, and the small cylinder 42 is injected together with ...

Embodiment 2

[0028] refer to Figure 7 When the mask 4 is installed, a glue bonding layer is pre-set on the back, and then the mounting hole 41 of the mask 4 corresponds to the second step 32 of the cylinder, and the end of the second step 32 is squeezed into the mounting hole 41, and the process is completed. Installation of mask 4. The rest of the parts are the same as those in Embodiment 1, and will not be repeated again.

[0029] Due to the interference fit between the second step 32 and the mounting hole 41 of the mask 4 and the effect of glue, the installation of the mask 4 is more firm. The column body 3 of the stepped structure not only ensures better bearing capacity, but also effectively solves the problem of small fixing space for the small-pitch LED display screen.

Abstract

The invention relates to a fixing structure for an outdoor small spacing LED (Light Emitting Diode) display screen module mask. The fixing structure comprises a bottom shell, an LED panel fixed on the bottom shell and a mask buckled on the LED panel, and is characterized in that the bottom shell is provided with a plurality of cylinders; through holes are formed in the positions, which correspond to the cylinders, of the LED panel and the mask; one end of each cylinder is fixed in the bottom shell, and the other end of each cylinder passes through one through hole of the LED panel and is fixed in an installation hole of the mask. In the fixing structure, one end, which has a large diameter, of each cylinder of a step structure is fixed in a preset bottom hole of the bottom shell, and one end with a small diameter can pass through one through hole in the LED panel and is fixed on one installation hole in a corresponding position of the mask through glue, good bearing capacity is guaranteed, and the problem of fixing difficulty of the small spacing LED display screen mask is effectively solved. Meanwhile, by interference fit between second steps and the installation holes and the function of glue, the mask can be more firmly installed.

Description

technical field [0001] The invention relates to the field of LED display screens, and relates to a fixing structure for an outdoor small-pitch LED display screen module mask. Background technique [0002] LED display is a display method by controlling semiconductor light-emitting diodes. It has high brightness, low power consumption, superior and stable performance, and long life. It is widely used in outdoor light box advertisements, stage backgrounds, and indoor TV walls. With the development of technology, people have higher and higher requirements for LED display screens in terms of resolution and contrast, so the use of small-pitch LED display screens is becoming more and more common. In the outdoors with strong light, in order to display better, the LED display needs to have a higher contrast, and in order to improve the contrast, a mask is often added to the LED panel. However, for small-pitch LED displays, due to the high resolution and the dense division of LED lig...
