Abstract
The utility model discloses a waterproof LED display screen, which comprises a unit circuit board including electronic components and connecting wires. The front surface of the unit circuit board is stained with waterproof glue; a waterproof glue layer with fine heat dissipation performance is arranged on the outer back surface of the unit circuit board; and the electronic components and the connecting wires on the back surface of the unit circuit board are covered completely by the waterproof glue layer. By adopting the double-surface gluing waterproof technology of the unit circuit board, an extremely thin glue film is formed on the outer surface of the unit circuit board, the waterproof LED display screen has fine waterproof, heat dissipation, anti-static and anti-corrosion performances, and can be directly operated without being disassembled and assembled when in maintenance. When the waterproof LED display screen is installed, no box or rubber band is needed, a module can be directly installed on a steel frame, cost is reduced, and the service life of the LED display screen is prolonged by more than 90%.
Description
[technical field]
The utility model relates to LED display, relates in particular to a kind of Waterproof LED display screen.
[background technology]
LED display: be electronic display again or the word screen that wafts.Be made up of the LED dot matrix, the light on and off by redness or green light pearl come display text, picture, animation, video, and content can be changed at any time, and the each several part assembly all is the display device of modular construction.What present known LED display was used is that the single face casing is crossed the glue waterproof, and weak point is its waterproof comprehensively, and it is bad that colloid is sealed the heat dispersion of electronic component partly, causes electronic chip to burn, the glue-line poor flatness, and colloid easily is corroded and wears out.
[summary of the invention]
The technical problems to be solved in the utility model provides the perfect LED display of a kind of water resistance.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of Waterproof LED display screen, comprise the element circuit plate, comprise electronic devices and components and connecting line on the element circuit plate, the front of element circuit plate is soaked with marine glue, and the back side skin of element circuit plate is a heat dispersion excellent waterproof glue-line, and Waterproof glue line all covers the electronic devices and components and the connecting line of element circuit backboard face.
Above-mentioned marine glue is an acrylic acid glue.
The beneficial effects of the utility model are, adopt the two-sided glue waterproof technique of crossing of element circuit plate, surface at the element circuit plate forms the very thin glued membrane of one deck, have excellent waterproof, heat radiation and antistatic performance, can directly change the bulb without dismounting during maintenance, need not to use casing during installation, directly the welding steel frame is contained on the module faceplate, cost reduces, and prolong more than 90% the serviceable life of LED display.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model Waterproof LED display screen example structure synoptic diagram.
Among the figure, 1-element circuit plate, 2-LED element, 3-integrated circuit block, 4-back side Waterproof glue line, 5-front Waterproof glue line.
[embodiment]
Fig. 1 is a kind of Waterproof LED display screen, comprise element circuit plate 1, comprise electronic devices and components on the element circuit plate 1, as electronic component and connecting lines such as LED element 2, integrated circuit blocks 3, the front of element circuit plate 1 is a Waterproof glue line 5, the back side skin of element circuit plate is a heat dispersion excellent waterproof glue-line 4, and back side Waterproof glue line 4 all covers the electronic devices and components and the connecting line of element circuit backboard face.
The employed marine glue of present embodiment is the acrylic acid glue with excellent waterproof heat dispersion, can guarantee the electronic component adorned on the unit circuit board 1, can operate as normal as bigger electronic components of thermal value such as integrated circuit blocks 3.
Specific practice:
Began glue under the intact situation of the electronic component on the determining unit circuit board 1, earlier marine glue is poured into receptacle, dilution is being poured into, and be blended together by a certain percentage, stirring got final product glue in general five minutes later on.Earlier the positive tiling of element circuit plate is immersed in the marine glue, by the time marine glue covers the various piece of wiring board electronic component and forms front glue-line 5 also after drying, and then cross glue and drying for equally the back side of element circuit plate 1, the skin at the back side (comprising components and parts and connecting line) of element circuit plate 1 has formed very thin one deck Waterproof glue line 4 too at last.
Claims (2)
1. Waterproof LED display screen, comprise the element circuit plate, comprise electronic devices and components and connecting line on the described element circuit plate, the front of element circuit plate is soaked with marine glue, it is characterized in that, the back side skin of described element circuit plate is a heat dispersion excellent waterproof glue-line, and Waterproof glue line all covers the electronic devices and components and the connecting line of element circuit backboard face.
2. Waterproof LED display screen according to claim 1 is characterized in that, described marine glue is an acrylic acid glue.
