Methods to Improve Waterproof and Dustproof Performance of Mini Touch Screen Monitor
1.Widen the border sealing rubber ring and adopt a composite sealing ring consisting of double-layer silicone and foam. Achieve full-perimeter closure for joints between the panel and cover plate, FPC wire outlets, and housing splicing seams to prevent dust infiltration from the sides. For outdoor and construction-site models, add stepped dust retaining grooves to block direct airflow of dust into gaps.
2.Upgraded full lamination process: Adopt optical liquid adhesive with strong adhesion and excellent gap-filling performance to minimize microbubbles and tiny gaps inside the laminated layer. Eliminate frame lamination completely to remove open side gaps that trap dust, fully blocking the path for dust to reach the ITO conductive layer.
3.Potting sealing for FPC cable outlets: Fill the wire holes with three-proof epoxy resin to seal gaps between cables and the housing, preventing dust from penetrating into the touch module through cable slits.
4.Glue dispensing treatment for all housing seams: Apply weather-resistant polyurethane sealant at shell joints, suitable for construction sites with sandstorms and dusty outdoor environments. It resists extreme temperature fluctuations without cracking or forming leakage gaps.
5.The cover glass surface is coated with a ceramic sputtered anti-fouling, hydrophobic and oleophobic layer, which reduces electrostatic adsorption of dust. Sand and dust particles barely adhere to the surface and can be easily washed away by rainwater or wiping, preventing water from seeping into the lamination layer through gaps along the cover edge.
6.An insulating dust-proof protective film is added on the surface of the ITO conductive layer. All operations before lamination are carried out in a dust-free workshop to eliminate residual dust generated during production. Vacuum defoaming is performed after lamination to remove micro voids between layers.
7.Install a front transparent dustproof protective window that is detachable for cleaning, which blocks large sand particles from directly impacting the gaps of the panel frame. Dustproof sealing strips are fitted on four sides of the protective window.
8.The whole equipment is equipped with a rainproof and dustproof protective cover, which can be closed during non-operation hours to isolate road dust and persistent suspended dust on construction sites.
FAQ
1.Q: What measures are used to prevent dust from entering the touch ITO layer?
A: We adopt full lamination process instead of frame lamination, add an insulating dust-proof film on the ITO surface, and complete all laminating procedures in a dust-free workshop to cut off all dust access to the conductive layer.
2.Q: How does the sealing structure stop side dust infiltration?
A: We widen the border sealing ring and use double-layer silicone-foam composite sealing strips. All seams of panels, covers, FPC outlets and housings achieve full-perimeter closure, with stepped dust retaining grooves added for outdoor construction models.
3.Q: How to seal the gaps at FPC wiring outlets against dust?
A: The FPC wire holes are fully potted with three-proof epoxy resin, which tightly fills the gaps between cables and the housing and avoids dust seeping into the touch interior through wiring slits.
4.Q: Why sputter a ceramic anti-fouling coating on the cover glass?
A: The ceramic coating delivers hydrophobic and oleophobic performance, reducing electrostatic dust adsorption. Sand dust can be washed off easily, and water is prevented from seeping into the lamination layer via edge gaps.
5.Q: What auxiliary dustproof accessories are equipped for construction and outdoor use?
A: Detachable cleanable transparent front dust-proof windows with four-side sealing strips are provided, plus an overall rain and dust shield that can be closed when the device is not in use to block continuous suspended dust.
