With the wide application of capacitive touch screen in the fields of consumer electronics, industrial control, medical equipment and automotive electronics, different use scenarios have put forward diversified requirements for the performance of touch screen. As an important part of the touch screen, the composite coating can meet the specific needs of different users through customized design to improve the performance, durability and user experience of the device.
First, the basic function and design requirements of composite coating
The composite coating is a key element in touch screen technology, which determines the performance of the screen such as wear resistance, anti-fouling, light transmittance and touch sensitivity. In custom design, different coating combinations and material choices can be adapted to specific needs, common design requirements include:
Antireflection property
In direct sunlight or strong light, the anti-reflective coating can reduce the reflected light on the screen surface and improve the display clarity. Suitable for outdoor equipment, automotive navigation screens and industrial touch screens.
durability
The hardened coating enhances the scratch and impact resistance of the screen, ensuring the long life of the device in high-frequency use scenarios, such as self-service terminals and public display devices.
Anti-fingerprint and anti-fouling
Oleophobic hydrophobic coatings reduce the adhesion of fingerprints and stains, keep the screen clean and bright, especially in consumer electronics products is an important factor in improving the user experience.
Conductivity optimization
High sensitivity touch requirements require a uniform distribution of conductive coatings to ensure fast response and multi-touch accuracy for medical instruments and high-end display devices.
Antibacterial property
In the field of medical devices and food processing, antibacterial coatings are critical. By introducing silver ions or other antibacterial materials, the screen surface can effectively inhibit bacterial growth.
2. Technical realization of customized design
1. Multi-layer coating combination
Custom designs are often achieved through a combination of multiple layers of coating. For example, in industrial touch screens, anti-reflection, hardening and oil repellent layers can be combined to provide comprehensive performance support. Special technology is used between the different layers to ensure durability and functionality.
2. Flexibility in material selection
The material selection of the composite coating directly affects the performance. For example:
The anti-reflection layer can be made of nano-silica material, which has excellent optical properties.
The conductive layer uses nano-silver wire or graphene, which is both highly conductive and flexible.
The antibacterial coating can choose silver ion or copper based materials, effective bactericidal and environmentally friendly.
3. Adjustment of thickness and coating process
Adjusting the coating thickness and process according to the application scenario is an important part of the customized design. For example:
High transmittance screens require thinner anti-reflection layers to ensure the display effect.
In industrial environments, the coating needs to be thicker to enhance impact resistance.
4. Intelligent manufacturing and personalized design
With intelligent manufacturing technology, custom designs enable individual requirements in mass production by precisely controlling coating formulation, distribution and thickness. Ai algorithms can also optimize coating designs based on product usage data, improving efficiency and performance.
Third, the practical application of customized design of composite coating
