How to Solve the Problems of Easy Bending Deformation and Poor Flatness for Long Strip Touch Modules?
1.Screws are fastened through a diagonal staged locking process, which involves gradual tightening in 2 to 3 steps with standardized torque applied each time. This prevents warping deformation caused by one-sided fastening and unbalanced torque.

2.The installation method that directly compresses the glass surface with screws is replaced by full-perimeter compression bonding via the front frame and highly elastic fluororubber buffer foam. The compression ratio of the foam is controlled within 30% to evenly distribute fastening pressure and prevent glass bending resulting from excessive local torque.

3.A mounting clearance of 0.2~0.3mm is reserved around the front frame to prevent mutual extrusion between the glass and housing under high-temperature thermal expansion, which would generate compressive stress and cause the glass to arch and bend. For long-strip modules, multi-point elastic support is adopted on the back instead of large-area rigid hard lamination.

4.Galvanized sheet metal parts with high flatness are selected for the backlight and iron frame, with the flatness tolerance of the backplane controlled within 0.1 mm per meter. If the backplane itself is uneven, it will directly pull the long-strip glass to deform after lamination. Any backplane exceeding the flatness tolerance must be leveled before assembly.

5.OCA adhesive with a thermal shrinkage coefficient matching that of glass and ITO film is selected. The adhesive layer shrinks evenly during high and low temperature cycling, avoiding glass warpage caused by local pulling or extrusion. Long-strip panels adopting the frame bonding solution are prone to deformation due to cavity air pressure and temperature fluctuations, so the full lamination process is prioritized.

6.Full flatness inspection is carried out on long-strip glass, ITO films and backlights before lamination, and raw materials with excessive warpage are directly rejected. Segmented vacuum lamination is adopted during the bonding process with slow pressure relief to prevent glass bending and local lamination bubbles caused by instantaneous uneven pressure over a large area.

7.High-temperature and high-pressure defoaming is performed after lamination to fully release the internal stress of the adhesive layer. The module is kept standing at room temperature for aging treatment for more than 24 hours before touch calibration, which enables complete release of material stress and prevents the shift of touch sensitivity caused by gradual deformation during later application.

How to Improve Sealing Performance
1.An integral full-perimeter foamed fluororubber sealing gasket is adopted, and four-segment spliced foam is prohibited to completely eliminate the risk of leakage from splicing gaps at the joints of segmented materials. The selected fluororubber features oil resistance, hydrolysis resistance and compression set no more than 15%, delivering superior compression consistency under long-strip working conditions and resisting rebound failure after high and low temperature aging.

2.The sealing groove adopts a continuous closed-loop milling design with the groove depth tolerance strictly controlled at ±0.05 mm, ensuring the compression ratio of the full-circle foam is uniformly maintained between 25% and 30%. This avoids uneven compression issues such as insufficient compression at both ends and over-compression in the middle for long-strip products. Large-radius transitional corners are adopted for the groove to prevent sealing leakage caused by extruded folds of the foam at corner positions.

3.The panel adopts a recessed mounting structure, with the cover glass embedded into the sealing groove of the front frame. Lateral limiting restrains changes in sealing clearance caused by slight warpage of the long-strip glass, so as to eliminate local sealing failure induced by minor glass bending deformation.

4.Dual redundant protection combining sealing strip compression sealing and continuous polyurethane dot bonding on the backside is adopted. Even if tiny gaps occur due to uneven compression of a certain section of the sealing strip, the continuous sealant can fully block the gaps to prevent the infiltration of water vapor and oil contaminants at single points. A high-thixotropy fast-curing sealant is selected for dispensing, and a high-speed long-strip dispensing equipment is used for constant-speed glue application to ensure consistent glue width and thickness throughout the entire path, with no glue shortage or breakage at corners.

5.Dot sealing is applied to the four edges of the glass to block tiny capillary gaps on the bonding sides between the cover glass and the ITO film, preventing liquid from seeping along interlayer capillary channels and corroding the edge wiring of the long-strip FPC.

6.For long-strip screens, the FPC outgoing position is preferably arranged on the short side to avoid the long sealing surface of the long side, so as to prevent the continuous sealing structure from being damaged by openings on the long side. If wiring from the long side is unavoidable, an integrated injection-molded sealed connector together with a waterproof cable gland with potting sealing shall be adopted.

FAQ
