Why ITO traces become visible on frame-bonded touch screens under high humidity
This article mainly elaborates two core parts: root causes for visible ITO circuits on frame-laminated touch panels in high-humidity environments and corresponding countermeasures against this defect. Different from full lamination, the frame bonding (edge bonding) process for touch screens retains an air gap between the touch layer and display layer; the screen periphery is fixed and sealed with double-sided adhesive or foam tape only. When stored long-term or powered on und

How to Choose Anti-Glare (AG) and Anti-Reflection (AR)
When selecting display enhancement coatings such as anti-glare (AG) and anti-reflection (AR), it is important to understand not only what they do individually, but also how they behave in real application environments. Many customers choose based on “what sounds better,” but in practice, the right choice depends on lighting conditions, viewing requirements, image clarity expectations, and even user interaction distance. Choosing correctly can significantly improve user experi

Why Does Touch Sensitivity Decrease After Touch Screen Laminated With LCD?
Introduction: Why does a single touch screen perform normally in bare testing, but after full lamination with an LCD display, it suffers from touch delay, discontinuous touch, insensitive pressing, touch drift, and edge touch failure? These issues are not caused by poor quality of the touch IC. Instead, they result from interference brought by interlayer structure, material superposition and internal stress. Meanwhile, how can we distinguish full lamination modules from air
