1.High-damping silicone pads and rubber dampers are installed between the screen and equipment housing to absorb vibration within 50~200Hz and cut down resonance transmission. The floating mounting structure avoids rigid hard connections.
2.Even buffer gaps and positioning ribs around the screen prevent shifting and squeezing under vibration. All fastening screws are fitted with lock washers and thread locker to avoid loosening during long-term vibration.
3.The touch display module is physically separated from strong vibration sources such as motors, transmission parts and working arms with increased spacing to reduce resonance superposition.
4.Adopt high-strength vibration-resistant optical adhesive to enhance the toughness and adhesion of the glue layer, resisting repeated stretching and shearing forces. Strictly control lamination pressure, temperature and defoaming parameters to ensure zero bubbles and incomplete bonding.
5.The module is fully sealed with special edge sealant around the perimeter to secure the layered structure, preventing edge glue separation and delamination caused by vibration and moisture. The basic dot gluing process is eliminated.
6.After lamination and edge sealing, the modules undergo constant-temperature aging and static standing treatment to thoroughly release internal process stress, preventing delamination accelerated by superposition of vibration and residual stress.
7.
8.All pads are reinforced with tin stacking and glue encapsulation, adopting high-temperature resistant and high-stability solder. Redundant pads are added for key signal points to eliminate cold solder joints and solder detachment completely.
9.Apply fixing glue to the bottom of both high and low components on the PCB to prevent component falling off under vibration. Adopt locking-type industrial connectors instead of common sockets to avoid accidental disconnection.
10.Adopt anti-vibration industrial touch IC with enhanced hardware filtering. Differential signal sampling is applied to suppress signal noise caused by mechanical vibration and reduce coordinate drift.
11.Route touch signal lines independently and keep them away from power cables and high-vibration components. Add magnetic beads and capacitors for filtering on key circuits to reduce vibration-coupled interference.
How to improve anti-false touch performance in humid environments such as rainy days?1.The cover glass is coated with high-performance AF hydrophobic and anti-fingerprint coating as standard. It increases the water contact angle, enabling rainwater and dew to form droplets and slide off quickly. This prevents water film from spreading across the surface and physically eliminates continuous false touches.
2.Enable liquid interference recognition algorithm. It identifies noise signals generated by large-area continuous water films and scattered water droplets to accurately shield false touches.
3.Lower the trigger weight of contiguous areas to distinguish manual operations from liquid interference. It maintains normal touch response and suppresses full-screen random touches.
4.Add delay judgment logic to filter transient touch signals caused by water droplets.
5.The touch and display module adopts full lamination plus full peripheral edge sealing to block gaps between layers and prevent moisture ingress from edges. A waterproof gasket is installed around the module to achieve first-level water resistance for the panel.
6.The equipment housing features IP67 or higher waterproof rating. Foamed waterproof strips are fitted at joints, and dedicated waterproof plugs or gaskets are used for screw holes and openings to prevent rainwater from seeping into the enclosure.
7.Install the screen with a downward tilt to avoid water pooling on flat or upward-tilted surfaces. Diversion grooves and edges around the panel guide rainwater to drain quickly and prevent water accumulation at corners.
FAQ
1.Q: Will rain and dew cause false touches on the screen?
A: No. The screen is coated with high-performance AF hydrophobic coating and equipped with liquid interference algorithms, which can effectively avoid false touches caused by water.
2.Q: What waterproof level does the touch module support?
A: The panel reaches first-level water resistance. Matched with IP67-rated housing and sealing accessories, the whole device can resist splashing and short-term water immersion.
3.Q: Does the waterproof design affect normal touch operation?
A: It won’t. The system can accurately distinguish human touches from liquid interference, ensuring sensitive and stable normal clicking.
4.Q: How to prevent water from seeping into the module interior?
A: We adopt full lamination and full-perimeter edge sealing to block gaps. Waterproof gaskets are also added around the module for double protection.
5.Q: Are there any installation requirements for outdoor use on rainy days?
A: It is recommended to install the screen with a downward tilt. The built-in diversion grooves can guide rainwater to drain quickly and prevent water accumulation.
