3.After lamination, the product undergoes high-pressure defoaming and high-temperature curing processes to eliminate internal bonding stress, preventing bubbling and edge warping caused by residual stress release after long-term vibration.

4.The screen is surrounded by a stainless steel bezel for even clamping, with symmetrical locking via four or six fixing points to avoid one-sided extrusion stress. The mechanical structure restricts displacement of the cover glass and shares the tensile force borne by the adhesive layer, physically preventing edge warping, shifting and delamination of the cover glass.

5.Highly elastic silicone buffer gaskets are fitted on the inner side of the metal bezel, which not only ensures uniform clamping pressure but also absorbs high-frequency vibration and impact. This avoids glass edge chipping and local stress-concentration-induced debonding caused by rigid compression from metal components.

6.The four corners of the cover glass are processed with rounded R-angle polishing to eliminate stress concentration at sharp corners, so edge debonding and warping rarely occur under vibration and impact.

7.The equipment casing reserves a stress buffer space inside the cavity, and interference fit between the screen module and the housing is prohibited. This avoids premature debonding failure caused by the superposition of assembly pre-stress and equipment vibration.

8.Thickened industrial-grade PI substrate FPC is adopted, with rolled copper foil instead of electrolytic copper. It can withstand tens of thousands of tiny reciprocating bends and boasts excellent fatigue resistance, so microcracks and open circuits of copper traces will hardly occur under long-term high-frequency vibration. A double-layer reinforcing steel sheet structure is added to reinforce the pad area and outgoing wire bending area, effectively preventing tensile fracture.

9.The FPC circuit adopts a redundant protection design, with dual redundant routing for key signal lines. A microcrack in a single circuit will not directly lead to a black screen or complete touch failure. The FPC surface is covered with an enhanced shielding layer, which delivers both EMI anti-interference performance and structural protection.

How to Improve the Impact Resistance of Touch Monitors in Application
1.High-alumina silicon cover glass is selected and treated via a secondary chemical strengthening process, forming a high-strength compressive stress layer on the glass surface with a surface compressive stress of ≥700MPa and a stress layer depth of ≥40μm. Compared with ordinary tempered glass, its resistance to impact, drop and hard object collision is more than tripled. It can withstand minor knocks and collisions from spanners, cutters and metal workpieces, greatly reducing the risk of glass breakage.

2.The four corners of the cover glass are polished with large-radius rounded chamfers to eliminate stress concentration at sharp edges and corners. Sharp corners are the most vulnerable positions prone to edge chipping and cracking upon impact. The large R-angle design evenly disperses instantaneous impact force and prevents direct cracking caused by collisions at the corners.

3.The screen is equipped with an aluminum alloy protective bezel and anti-collision metal surround, which protrudes 0.8~1.5 mm above the glass surface to form a physical anti-collision barrier. When tools or workpieces collide with the device, the impact first acts on the metal frame instead of the cover glass, fundamentally avoiding the risk of glass breakage from direct impact. The metal bezel undergoes passivation and plastic spraying treatment, delivering excellent anti-corrosion and wear-resistant properties.

4.The back of the module is fitted with highly elastic silicone buffer pads for flexible mounting. This prevents impact force from being rigidly transferred directly to the glass. The buffer structure absorbs impact energy to protect the cover glass from cracking under concentrated stress.
