1.We adopt industrial-grade capacitive touch IC designed for thick glove operation. By increasing charge sampling gain and lowering the touch trigger threshold, the screen supports direct operation with cotton gloves, nitrile rubber gloves and standard labor leather gloves without the need to take off gloves.
2.Optimize the design of the ITO touch layer: adopt high-conductivity and low-impedance ITO circuits with a thickened conductive ITO layer to enhance the ability to capture weak capacitive signals and reduce signal attenuation, ensuring stable acquisition of touch signals even under glove pressing.
3.The touch FPC is designed with an additional shielding layer to mitigate electromagnetic interference generated by on-site inverters, motors and high-power equipment. It prevents touch drift and ghost touches under high-gain mode, making it suitable for heavy electromagnetic working conditions such as machine tools and heavy industry machinery.
4.
OCA full lamination process is prioritized to eliminate signal attenuation caused by the air layer in frame bonding, delivering stronger touch sensing penetration. It enables compatibility with thicker safety gloves under the same gain setting. The air layer in frame-bonded structures weakens the electric field, which often leads to touch failure when operating with thick gloves.
5.The cover glass adopts ultra-thin aluminosilicate tempered glass. While meeting IK08/IK10 explosion-proof and impact resistance standards, the glass thickness is properly optimized to reduce the attenuation of the touch electric field caused by the glass medium, greatly improving the touch sensitivity for glove operation.
6.Adopting AG anti-glare + AF hydrophobic dual coating on the cover glass does not affect electric field penetration. It delivers excellent visibility under strong outdoor light as well as water repellency and false touch prevention, perfectly adapting to assembly lines and humid workshop environments.
How to reduce the corrosion of FPC caused by moisture under extreme weather conditions?1.The mating surfaces between the front screen, front frame and front & rear housings adopt dual sealing with continuous silicone dispensing plus high-temperature resistant silicone sealing foam to eliminate gaps caused by intermittent glue application or missing glue. Waterproof washers are fitted to all fixing screws to prevent water vapor ingress through gaps generated by thermal expansion and contraction.
2.The FPC cable outlet adopts sealing methods including cable gland locking, integrated injection vulcanization sealing for FPC, or double-layer potting sealing with epoxy resin and silicone. It completely seals the gaps around leads to prevent moist air from being sucked in under negative pressure.
3.High and low temperature resistant waterproof breathable valves are installed on the rain-shielded, non-direct-sunlight side walls of the equipment to balance the internal and external air pressure of the cavity. This prevents moist air from being drawn in under negative pressure or the sealing layer from being damaged under positive pressure caused by temperature differences between day and night. While maintaining the cavity’s dustproof and waterproof sealing performance, the valves enable gas exchange, fundamentally reducing the occurrence of internal condensation.
4.The optical adhesive fully fills the air gap between the cover glass and LCD to eliminate enclosed air inside the interlayer, preventing condensation caused by temperature difference from corroding the ITO touch electrodes. Meanwhile, it improves touch stability, supports operation with thick gloves and restrains ghost touches triggered by water film.
5.The touch drive board, backlight drive board and main control board are coated with thickened polyurethane three-proof paint, which fully covers the FPC golden fingers, ITO lead solder joints and component pins. It improves moisture resistance, corrosion resistance and insulation performance, and prevents electric leakage and circuit corrosion caused by condensation.
6.High-power heat-generating components and touch ICs are placed in an elevated layout, keeping them away from water-prone areas at the bottom of the cavity. Hydrophilic flow-guiding structures are reserved along the board edges. If a tiny amount of water vapor seeps in, it will flow down along the guide ribs to the bottom area, far away from circuits and electrodes.
7.High-efficiency molecular sieve desiccants are placed inside the sealed cavity to absorb residual moisture and control the relative humidity within the enclosure, preventing water vapor saturation and condensation. For mass-produced equipment, a detachable desiccant compartment can be designed to facilitate regular replacement and maintenance.
FAQ1.Q: How to avoid FPC and internal circuit corrosion caused by moisture and condensation in extreme weather?A: We adopt multiple protective measures. The FPC connector pads are gold-plated and the whole circuit board is sprayed with thick polyurethane conformal coating to isolate water vapor and corrosive substances. Meanwhile, waterproof sealing structures are used for FPC outlets and housing joints to stop humid air from entering the equipment cavity.
2.Q: What designs can balance internal and external air pressure to reduce condensation?A: High and low temperature resistant waterproof breathable valves are installed on the shaded side wall of the device. They realize gas exchange inside and outside the sealed cavity, avoid negative pressure or positive pressure generated by day-night temperature differences, prevent moist air inhalation and sealing damage, and fundamentally reduce internal condensation.
3.Q: Why is OCA full lamination helpful for moisture-proof protection of touch electrodes?A: Optical adhesive completely fills the air layer between cover glass and LCD, eliminating closed air inside the interlayer. It avoids condensation formed by temperature differences from corroding ITO touch electrodes, also optimizes touch stability for thick glove operation and effectively eliminates ghost touches caused by water film.
4.Q: What layout designs prevent circuit damage from accidental water seepage inside the device?A: Heat-generating power components and touch ICs are arranged at elevated positions away from the easily waterlogged bottom of the cavity. Flow guide ribs are reserved on the edge of the circuit board to guide tiny seeped water to the bottom drainage area, keeping liquid away from sensitive circuits and electrodes.
5.Q: How to continuously control humidity inside sealed equipment for long-term anti-condensation performance?A: High-efficiency molecular sieve desiccants are placed inside the sealed cavity to continuously absorb residual moisture and control internal relative humidity. Detachable desiccant bins can be reserved for mass-produced equipment, enabling regular replacement to maintain long-term moisture-proof and anti-corrosion effects.
6.Q:What glove types are supported by your industrial capacitive HDMI touch display?A:Our industrial touch screen is fully compatible with various glove types, including cotton, nitrile, and leather. We optimize the ITO touch layer and use industrial-grade ICs to ensure precise multi-touch response even when operators wear gloves during industrial operations.
7.Q:Can you customize the capacitive touch display size or features for specific industrial applications?A:Yes, we provide flexible customization options. Our R&D team supports in-depth design changes, and we can adjust sizes, interfaces, and coatings per your project needs. We cater to industrial touch panel manufacturers seeking tailored solutions for specialized environments.
8.Q:How do you ensure the durability and reliability of your HDMI touch screen in harsh industrial environments?A:We apply ultra-thin aluminosilicate tempered glass with IK07 impact resistance and anti-glare, hydrophobic coatings for moisture and visibility. Full lamination optical bonding prevents condensation, while EMC shielding reduces interference, ensuring our industrial touch screen maintains consistent accuracy.
9.Q:What are the shipping and warranty terms for your capacitive HDMI touch display?A:Our touch screen display manufacturers offer a minimum order quantity of one unit. Every product includes a 3-year warranty covering manufacturing defects. We ensure efficient delivery and provide technical support to help you integrate our HDMI touch screen into your industrial systems.
