1.The OCA full lamination combined with UV edge sealing technology delivers seamless bonding between the cover glass and LCD panel, eliminating frame gaps and preventing salt spray, moisture and dust from seeping into the lamination layer through the side edges.
The front side of the whole module adopts dispensing sealing treatment together with EPDM weather-resistant sealing gaskets, achieving IP65 front-side protection against dust, salt spray and water ingress.
2.Potting sealing and hot-pressing protective structure are adopted at the FPC outlet position. The cable outlet is sealed with salt-spray resistant polyurethane sealant to prevent salt spray from penetrating into the interior along gaps of the flexible cable and corroding the circuits.
3.The FPC gold fingers adopt an enhanced gold plating process with thick gold plating for superior salt spray resistance. A three-proof coating (moisture-proof, salt spray-proof and mildew-proof) is sprayed on the surface to fully cover all exposed circuit areas and isolate corrosion caused by chloride ions and dust. All unused circuit contacts are insulated and sealed with adhesive.
4.A transparent three-proof protective coating is sprayed on the ITO conductive area and drive circuit surface of the LCD screen to prevent leakage, open circuits and touch drift failure caused by salt spray deposition. Weather-resistant shielding and insulating adhesive is attached to the outer side of the FPC, which provides both dustproof performance and protection against electrochemical corrosion.
5.High-alumina silicon tempered cover glass is adopted and processed with two rounds of chemical strengthening to improve surface hardness and resist scratches caused by wind-blown sand friction.
6.Based on fine-frost AG and AR coatings, a long-lasting hard AF anti-fingerprint hydrophobic and oleophobic coating is applied. Compared with conventional soft AF coatings, it features several times higher abrasion resistance and is not prone to peeling off under wind-sand friction.
7.The edges of the cover glass are processed with precision CNC chamfering and polishing to eliminate sharp corners. This reduces stress abrasion on the edges caused by wind and sand, and prevents tiny cracks from edge collisions that would otherwise lead to coating damage and moisture ingress.
How to Improve Touch Accuracy of Touch Modules When Wearing Gloves in Practical Applications
1.High-sensitivity industrial capacitive touch IC is adopted to increase the driving transmission voltage and optimize the signal sampling algorithm. It supports direct touch operations with thin rubber gloves, thick cotton labor gloves and leather gloves. Users can achieve accurate tapping and sliding without taking off gloves, featuring stable touch response and no touch point loss.
2.A multi-channel touch circuit layout with high signal-to-noise ratio is adopted to reduce environmental interference. It can stably identify weak induced signals from gloved operations under humid conditions and electromagnetic interference working scenarios, eliminating touch failure and intermittent touch issues.
3.The touch panel is equipped with a waterproof touch algorithm featuring large-area water stain suppression. When rainwater or continuous water stains appear on the screen surface, the system automatically shields global false touch signals and only identifies valid local single-finger touch points, eliminating multi-point drift, coordinate jumping and misoperation caused by flowing rainwater.
4.The cover glass is coated with a durable hard AF hydrophobic and oleophobic coating. Raindrops quickly condense into water beads and slide off the screen instead of forming a continuous water film on the touch surface, which physically reduces touch abnormalities triggered by large-area water stains.
5.The screen adopts OCA full lamination plus UV edge sealing process, together with an IP65 sealing structure for the whole module. It prevents rainwater and moisture from penetrating into the touch layer through frame gaps, avoids leakage of electricity on FPC circuits and ITO conductive layers caused by dampness, and fundamentally resolves touch drift and malfunction resulting from humid conditions.
6.Three-proof coating with moisture-proof, mildew-proof and salt-spray resistant properties is applied to the FPC touch cables and drive mainboard area. It ensures stable circuit insulation in humid outdoor environments and prevents disordered touch signals caused by water vapor.
FAQ
Q1: Can this touch module support stable operation when wearing various industrial gloves?
A1: Yes. We adopt high-sensitivity industrial capacitive touch IC with boosted driving voltage and optimized signal sampling algorithm. It enables precise tapping and sliding with thin rubber gloves, thick cotton labor gloves and leather gloves, delivering steady touch response without missing touch points. Besides, the large-channel, high-SNR circuit layout restrains electromagnetic and humid environmental interference to stably capture weak touch signals from gloved fingers and avoid no response or intermittent touch failures.
Q2: Why won’t continuous rainwater cause touch misoperation on your touch screen?
A2: The touch panel is embedded with a professional waterproof touch algorithm supporting large-area water stain suppression. When there are rain drops or connected water films on the screen, the system will automatically filter global false touch signals and only identify valid single-point touches, preventing coordinate drift and random misoperations caused by flowing rainwater. Meanwhile, the durable hard AF hydrophobic and oleophobic coating on the cover glass makes raindrops bead up and slide off rapidly, effectively avoiding the formation of continuous water films on the touch surface.
Q3: What structural designs are used to prevent touch failure caused by moisture ingress?
A3: We apply OCA full lamination combined with UV edge sealing technology, together with the overall IP65 sealed structure. This blocks rainwater and moisture from seeping into the touch layer via frame gaps, thus protecting FPC wires and ITO conductive layers from damp-induced electric leakage and fundamentally eliminating touch drift and malfunction due to humidity.
Q4: How do you protect internal circuits from humid and corrosive outdoor environments?
A4: The FPC touch flexible cables and drive mainboard are fully sprayed with three-proof coating that features moisture-proof, mildew-proof and salt-spray resistant performance. It maintains reliable circuit insulation under humid outdoor conditions and effectively avoids chaotic touch signals triggered by water vapor infiltration and circuit corrosion.
Q5: In complex industrial scenes with strong electromagnetic interference and high humidity, can gloved touch still keep high accuracy?
A5: Absolutely. Our touch module uses a large-channel and high signal-to-noise ratio touch circuit layout to suppress external environmental interference. Even under high humidity and severe electromagnetic interference, it can accurately recognize weak induction signals from gloved touches, thoroughly solving common faults such as touch no response, intermittent touch and touch point offset.
