Spacer Dots

Spacer dots are microscopic spacers placed between layers of a touch panel, most commonly in air bonding technology, to maintain a consistent and even gap between the top cover (e.g., glass) and the lower sensor layer. Without spacer dots, panels may suffer from short circuits, false touches (ghost touches), or deformation under pressure. These nearly invisible structures, typically a few dozen micrometers in diameter, are made of transparent polymers or resins. Despite their tiny size, they are essential for ensuring touch panel stability, accuracy, and durability when layers are separated by an air gap.
