1.The driving voltage is increased to 12V～18V (only 5V for ordinary consumer touch screens), which greatly enhances electric field penetration capacity. It supports stable touch operation through 1–3 mm thick labor gloves made of rubber, cotton yarn or nitrile materials.
2.The channel sampling frequency is raised and the signal-to-noise ratio is amplified to filter clutter generated by glove fibers and rubber, eliminating discontinuous touch and intermittent unresponsive issues.
3.The conductive cross-sectional area of sensing electrodes is enlarged to reduce sheet resistance and boost electric field radiation intensity, enabling the electric field to penetrate thick insulating glove media. Ordinary single-layer thin ITO delivers weak electric fields, which get fully blocked by thick gloves and lead to signal loss.
4.Boost the intensity of sensing signals to prevent signal attenuation below the recognition threshold when thick gloves are in contact. The electrodes are arranged in an encrypted grid layout to balance penetration performance and touch accuracy.
5.Dual-layer sensing generates superimposed electric fields for maximum penetration capability, compatible with 3 mm extra-thick rubber shockproof gloves and multi-layer cotton labor gloves.
6.Full lamination with low-dielectric-constant OCA optical adhesive reduces electric field attenuation inside the adhesive layer, delivering over 40% higher penetration performance compared to bare screens with air gaps.
Solutions to Unresponsive Touch Caused by Surface Stains1.The water contact angle reaches ≥110° and oil contact angle ≥70°. Cutting fluid, machine oil and water droplets will quickly shrink into spheres and roll off the glass surface instead of spreading out to form a conductive liquid film.
2.The coating remains intact and free of haze after 10,000 reciprocating rubs with steel wool, and withstands repeated wiping with alcohol, cutting fluid and rust remover.
3.
Low surface energy prevents grease and cutting fluid from adhering firmly; stains can be wiped off effortlessly without residual oil film.
4.Etched matte AG substrate paired with double-layer AF coating is applied for mining and heavy processing scenarios featuring intense strong light and splashing emulsified fluid.
It effectively eliminates glare for clear parameter viewing while maintaining superior hydrophobic and oleophobic performance, preventing the matte layer from whitening upon oil contact and liquids from spreading into continuous films.
5.Plasma cleaning is performed on the glass surface before coating to remove release agents and dust, preventing coating peeling and partial performance failure after long-term immersion in oil contaminants.
6.High-density fine-grid ITO sensing electrodes enable finer partitioned single-point capacitance sampling. Local liquid interference only affects a tiny area and will not cause full-screen coordinate drift.
FAQQ1: Why do oil, water and cutting fluid cause touch drift or unresponsiveness on ordinary touch screens?A1: Water, oil and emulsified liquid spread into a continuous conductive film on glass, shielding the ITO electric field and interfering with capacitance sampling, resulting in coordinate drift, broken touch or complete failure of the whole screen.
Q2: What coating design prevents liquid from spreading into a conductive film?A2: We adopt double-layer AF coating with water contact angle ≥110° and oil contact angle ≥70°. Water, machine oil and cutting fluid shrink into spherical droplets and roll off without spreading into a connected liquid film. The glass substrate is etched matte AG to avoid glare in bright heavy industry environments.
Q3: Is the anti-fouling coating wear-resistant under frequent wiping and friction?A3: Yes. The coating stays intact and haze-free after 10,000 reciprocating steel wool abrasion. It also resists repeated wiping with alcohol, cutting fluid and rust remover. Plasma cleaning before coating eliminates release agents and dust to stop coating peeling after long-term oil exposure.
Q4: How to avoid full-screen touch drift when splashed by emulsified liquid in workshops?A4: Equipped with high-density fine-grid ITO electrodes for refined partition capacitance sampling. Local liquid interference only covers a tiny range and will not trigger full-screen coordinate drift. Matching stain suppression algorithm further filters liquid clutter signals.
Q5: What advantages does etched AG + double-layer AF bring for mining and heavy processing?A5: The matte AG substrate eliminates strong outdoor/equipment glare for clear parameter reading. The double-layer AF retains strong hydrophobic-oleophobic properties, solving the common problem that matte layers turn white after contacting oil and liquid spreading across the screen. Low surface energy also makes oil and emulsion easy to wipe without residual oil film.
