5 practical guidelines for selecting touch screen functional film processes

As a touch screen manufacturer, Xinlilai Optoelectronics is well aware that process selection directly affects the success or failure of products. Starting from practical production experience, this article shares 5 key decision-making factors to help you avoid pitfalls.
 

Guide 1: First, look at the product positioning
Consumer electronics (mobile phones/tablets): Yellow light technology must be selected, otherwise it cannot meet the requirements of narrow borders and high touch precision
Home appliances/industrial equipment: silk screen printing is more cost-effective, such as air conditioning control panels, elevator button screens
 

Guide 2: Pay attention to environmental adaptability
High temperature and high humidity environment (such as car touch screen): ITO layer with yellow light technology is more resistant to aging
Outdoor equipment: Silk screen silver paste requires additional anti oxidation treatment
 

Guideline 3: Flexible requirements determine the process
Flexible substrate (PET/PI) can only be processed with yellow light technology, and the silk screen printing paste is prone to cracking
Both hard glass substrates are acceptable, but curved glass has a preference for yellow light
 

Guide 4: Delivery Time and Capacity Balance
Urgent orders (<2 weeks): silk screen printing is faster
Long term stable orders: Yellow light technology has a higher yield and may result in lower total costs
 

Guide 5: Certification and Compliance Requirements
Medical/automotive grade certified products: yellow light process is usually mandatory
Ordinary civilian products: silk screen printing can meet the requirements
