Why should a capacitive touch screen be covered with something?

Today, let's talk about why our capacitive touch screen needs to be covered immediately after vacuum defoaming. Because our capacitive touch screen is a cover plate of glass structure and a functional piece of glass structure, the layer of optical adhesive we use for bonding before bonding is referred to as hot melt adhesive, and this layer of hot melt adhesive generally cannot be removed after UV irradiation, which means that it will solidify after exposure to light.
Therefore, in general, the capacitive touch screen we vacuum out will cover it to block out the light, to prevent any defects found during cleaning. We can better handle reverse disassembly and re fitting.
