Can Prevent Black Border of Cover Glass from Fading in the Direct Sunlight?

Is the colored border of your touchscreen fading in the direct sunlight？

Is the colored border of your touch screen turning yellow in the direct sunlight?

Is the ink printed on your touchscreen border falling off in the direct sunlight?

Above-mentioned situations often happen on touch screens; especially those touch screens placed outdoors long-time in the direct sunlight. Such situations are caused by the ultraviolet (UV) light in the sunlight. Usually, there are 4 methods to solve this issue:

Method #1: using UV resistant ink by silk printing process

Method #2: using clear UV coating to protect it by silk printing process

Method #3: using high-temperature ink to protect it

Method #4: using high-temperature ink and sintering the ink into the glass by heat

LB takes method #4 to meet the requirement of assembling the cover glass on an outdoor touch screen. The first 3 methods are all considering preventing the UR ray and the key point is on the ink or coating. Method #4 is working on the ink adhesive force on the glass. This is the safest method, as the ink has already been sintered into the glass, not only on the surface. When the temperature is close to the melting point of glass, the ink is sintered into the glass. You can even use a knife to scratch the ink. The ink and the glass are melting together, just like the ink poured in the water.
