Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The potting device provided by the embodiment of the present invention has simple structure, simple preparation process, convenient operation, and low production cost. In actual use, only the potting glue needs to be injected into the potting cavity, and then the LED display screen needs to be filled. Just immerse the packaged part in the glue. The process of the entire potting operation is very simple, and no air bubbles will be generated, and subsequent vacuum or high-pressure degassing treatment is not required, which greatly simplifies the entire glue filling process and improves the glue...

Abstract

The invention is suitable for the technical field of photoelectricity, and provides a potting device, an LED display screen and a packaging method of the LED display screen. The potting device is simple in structure, simple in preparation process, low in production cost, suitable for batch production of potting products, and high in production efficiency; a dam colloid is applied between a first fitting layer and a second fitting layer, and the dam colloid is aligned and fitted to form a potting cavity with three closed sides and one opened side, so that the surface of the product is smooth, the overall thickness is consistent, the display effect is good, and the display distortion caused by non-uniform thickness of the potted product is avoided; besides, a height limiting strip with the height equal to the thickness of the potting cavity or the height of the dam colloid compressed after attachment is placed on the colloid applying surface of a certain attachment layer, the height uniformity of the potting cavity can be guaranteed, therefore it can be guaranteed that after encapsulation and potting, the surface of a product is smooth, the overall thickness is consistent, and the display effect is good.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to a potting device and a preparation method thereof, an LED display screen and a packaging method thereof. Background technique [0002] The LED display screen is an electronic display screen composed of LED dot matrix. A certain number of light-emitting diodes are arranged on the circuit board according to the rules, and the screen formed by the LED lamp bead dot matrix on the circuit board emits light. Transparent LED display is a new type of LED display technology that uses flexible circuit boards instead of hard printed circuit boards. Compared with conventional LED screens, transparent LED displays are more transparent, more beautiful, lighter, and more in line with the current market. For outdoor advertising needs. [0003] The LED lamp beads of the transparent LED display are relatively fragile, and they are prone to bump damage, solder pads falling off ...
