[0015] The application provides an IP68 dustproof and waterproof serial port screen, which effectively solves the protection of the dustproof and waterproof of the liquid crystal display screen of the existing device, so that the display abnormality or failure of the liquid crystal screen caused by water entering the inside of the liquid crystal screen is avoided.

[0016] EMBODIMENT

[0017] As Figure 1As shown, the technical scheme in the embodiment of the application effectively solves the technical problem that the existing device protects the liquid crystal display screen from dust and water, thereby causing the display abnormality or failure of the liquid crystal screen due to water entering, and the general idea is as follows: an IP68 dustproof and waterproof serial port screen, comprising a CG cover plate 5, a touch screen sensor 6 arranged above the CG cover plate 5, the CG cover plate 5 and the touch screen sensor 6 being in a pasting state, a liquid crystal display module 7 adhered on the CG cover plate 5 and the touch screen sensor 6, a metal part 4 installed on the CG cover plate 5 and the touch screen sensor 6, a structural adhesive 1 filled in the gap between the metal part 4, the CG cover plate 5 and the touch screen sensor 6, a printed circuit board 2 installed on the metal part 4, a uniform spacing being kept between the printed circuit board 2 and the liquid crystal display module 7, a potting adhesive 3 filled between the liquid crystal display module 7 and the printed circuit board 2, the potting adhesive 3 completely covering the components on the printed circuit board 2, a waterproof terminal 8 installed on the printed circuit board 2, and the CG cover plate 5, the touch screen sensor 6 and the liquid crystal display module 7 all being connected with the printed circuit board 2 through a flat cable and exceeding the upper surface of the highest component by a certain thickness.
