Solutions to Improve Anti-Aging Performance Under Long-Term Sun Exposure
1.The substrate is doped with UV-blocking ions, which can block over 99% of ultraviolet rays below 380 nm, minimizing UV penetration into the module at the source.

2.It adopts an inorganic silicon base layer combined with a long-lasting fluorinated top layer, remaining stable without decomposition after 500 hours of UV accelerated aging test.

3.The water contact angle remains ≥110° for a long time and will not turn hydrophilic after sun exposure, eliminating false touches caused by condensed water film formed by sunlight combined with day-night temperature difference.

4.Exposed glass edges are weak points for UV penetration. UV-resistant black insulating ink is coated on the sides to block ultraviolet rays from infiltrating the OCA and sensor layers through the edges.

5.UV-resistant silicone rubber is selected for frame sealing on models with air interlayers; ordinary foamed double-sided tape is not adopted, as it will powder, crack and cause water leakage after short-term sun exposure.

6.Dual-sided borosilicate glass ITO sensor features an inorganic glass substrate resistant to UV degradation. The ITO conductive layer avoids oxidation and sheet resistance rise, delivering stable touch baselines without point loss or drift even under year-round sun exposure.

7.UV-stabilized ITO-PET is adopted: UV absorbers are blended into the substrate, and a UV-resistant hardened HC coating is laminated on the surface.

How to Improve Touch Accuracy with Gloves
1.Enlarge the sensing electrode area and optimize large electrode layouts in rhombus or hexagonal shapes to increase the receiving area of coupling capacitance.

2.Reduce the resistance of silver traces to minimize signal transmission attenuation, ensuring faint signals from thick gloves are not lost.

3.Suitably narrow electrode gaps to boost overall sensing sensitivity, while suppressing water film interference via algorithms.

4.Prioritize standard tempered cover glass of 1.1mm / 1.5mm thickness; overly thick cover glass will drastically attenuate glove touch signals. If customers specify thicker cover glass, the IC driving power will be increased synchronously for compensation.

5.Adopt high-conductivity AF hydrophobic coating to prevent thick insulating films formed by oil stains and coolant on the screen, which would otherwise result in complete signal loss when wearing gloves. Oil residues can be easily wiped off without impairing touch sensing performance.

6.Matched wide-temperature resistant materials: OCA and glass sensors with temperature resistance ranging from -40℃ to 85℃, so there is no sensitivity attenuation under low-temperature cold chain environments.

FAQ
Q1. How to improve the recognition sensitivity of thick work gloves?
A1. Multiple hardware optimizations work together: enlarge the area of rhombus/hexagonal sensing electrodes and narrow electrode gaps to boost coupling capacitance reception; reduce silver line resistance to cut signal transmission loss. Standard 1.1mm / 1.5mm thin tempered cover glass is preferred. For thick cover glass solutions, the driving power of touch IC will be raised synchronously for compensation to avoid loss of weak capacitive signals.

Q2. Touch fails easily with gloves when oil or cutting fluid covers the screen, how to fix it?
A2. High-conductivity AF hydrophobic coating is standard equipped. It prevents oil stains and coolant from forming insulating films that cause total signal loss when wearing gloves. Contaminants can be wiped off easily without weakening capacitive sensing, stable for industrial oily environments and glove operation.

Q3. Touch response becomes slow with gloves in cold chain low-temperature environments, what is the solution?
A3. Ordinary adhesives and sensors suffer sensitivity attenuation at low temperatures. Our product adopts fully matched wide-temperature OCA and glass sensors supporting -40℃~85℃. The sensing performance remains stable under low temperatures without lag or disconnection when operating with thin or thick gloves.

Q4. Higher electrode sensitivity leads to random false touches caused by condensed water film, how to solve this?
A4. Electrode gaps are narrowed to enhance basic sensing sensitivity, while dedicated touch algorithms are applied to suppress water film interference. The module can identify weak glove signals and filter capacitive noise from condensed water and stains to eliminate false touch and coordinate drift.

Q5. Why is cover glass thicker than 2mm not recommended for glove touch?
A5. Thick cover glass greatly attenuates the weak coupling capacitive signals generated by gloves, resulting in no response to taps or broken lines during sliding. Standard 1.1mm / 1.5mm tempered cover glass is prioritized for general working conditions. If thick cover glass is required by customers, IC driving power will be increased to compensate signals and guarantee glove touch accuracy.
