Abstract

Disclosed is a new structure of a protection sheet for a touch panel. The protection sheet consists of a PET film with non-glared hard coat and spacers printed by screen printing.(Figure 1) This structure prevents from wrong responses caused by dust,and allows users to choose thick of protection sheets. The conventional technology prevents from this problem by using a thin film,but it is vulnerable to damage.(Figure 2) Since this strucure compulsorily makes an air layer between the touch panel and the protection sheet(Figure 3),the protection sheet does not stick on the touch panel. Even if there is dust between them ,the touch panel responds correctly despite of the thickness of the protection sheet. N ew structure protection sheet
