Touch screens have become the core technology of modern human-computer interaction. From mobile phones to industrial equipment, their high flexibility, efficient operation, convenient interaction and intelligent features have significantly improved user experience and work efficiency. In the future, with the development of flexible display, AI and tactile feedback, touch screens will be more seamlessly integrated into life and production scenarios. However, with the development of technology, different industries have different requirements for touch control. We have dealt with this as follows:
Anti-reflection (AR)
Anti-reflection, in English Anti-Refection, referred to as AR, is to coat a layer of anti-reflection film on the surface of the LCD display touch screen substrate to form some interfaces, so that the light waves reflected back through each interface will produce destructive interference with each other, increase the transmittance, reduce the reflectivity, thereby increasing the clear image quality of the LCD display touch screen to reduce the glare phenomenon.
1. For a single-sided single-layer AR architecture, the transmittance can be increased to 92%, and for a double-sided double-layer structure, it can be increased to 94%.
2. Fingerprints can easily damage the AR coating, so an additional layer of anti-fingerprint film (AF) is usually added.
Coating
Single coatingT=91-92%
Double CoatingT=92-94%
Anti-fingerprint (AF)
Anti-fingerprint, in English Anti-Finger, referred to as: AF, mainly uses the lotus leaf principle to coat a layer of low surface energy tension film on the surface of the LCD display touch screen substrate. Generally, it is a fluorine-containing coating to reduce the surface tension of the substrate to the minimum, making it have strong hydrophobic and oleophobic and anti-fingerprint capabilities; thereby reducing the surface free energy of the LCD touch screen (usually <30mN/m), making it difficult for grease to adhere.
1. Stains are not easy to adhere and easy to clean. Contact angle: usually >105° (about 70° for ordinary glass) Oleic acid contact angle: >80°;
2. Good wear resistance, not easy to scratch, steel wool friction test (500g load, contact angle remains >95° after 500 times)
Artificial sweat immersion test (performance decay <10% after 24 hours),
3. Small dynamic friction coefficient, smooth surface, comfortable feel:
4. Form a transparent antifouling film without affecting the appearance of the product
Anti-glare (AG)
Anti-glare, in English Anti-Glare, referred to as AG, is a key technology to improve the visibility of touch screens in strong light environments. It improves the display clarity by controlling the surface light reflection and scattering characteristics. It is to achieve the effect of multi-angle diffuse reflection after the surface of the ICd display touch screen substrate is specially treated on one or both sides, thereby improving the ICd display touch screen film. Anti-fingerprint effect can also be added to the coating to further optimize the surface feel. Through the scattering and diffuse reflection of light, the reflection is reduced to achieve the purpose of anti-dizziness and anti-glare, so as to create a clear and transparent visual space, so that the ICd display touch screen has a better visual enjoyment.
After these treatments, the probability of interface failure caused by oil stains was greatly reduced, and it was also easier to clean. The order processing capacity during peak hours increased by 3 times, and 30% of customers also increased their consumption due to this personalized recommendation, and received faster and more convenient service.
