Sturdy, sturdy glass

We have already reported on Gorilla Glass in various blog posts. If you search for the term on the Internet, you will also notice that many suppliers excel in using Corning's Gorilla Glass in their products. It is no secret that many smartphones, tablet PCs or large flat screens attach the glass to protect it from the outside world. But what makes Gorilla Glass different from other glass?

We have written several times about the US company Corning, Inc., based in Corning, New York, which produces glass, ceramics and related materials for industrial and scientific applications. Among other things, one of Corning's best-known products is Gorilla Glass, which was launched in 2007. It is characterized by high resistance to breakage and scratches.

The car manufacturer Range Rover not only equips the center console of its cars with touchscreen technologies, but also uses touch displays for other functions. An app from the manufacturer now makes it possible for the touchscreen of a smartphone to act as a remote control for its new Range Rover Sport off-road vehicle.

Graphene is a chemical relative of diamonds, coal or the graphite of pencil leads. It is one of the hardest and most resilient materials in the world. With only one atomic layer (less than a millionth of a millimeter thick), it is also one of the thinnest materials in the universe.

Linear thermal expansion is a critical factor to consider in environments with wide temperature requirements, as it can cause problems due to different thermal expansion coefficients of touch screen materials or the bezel structure. Different coefficients of thermal expansion can be defined for a substance, such as linear thermal expansion (LTE), area thermal expansion (ATE), or volumetric thermal expansion (VTE). Some substances expand when cooled, such as freezing water, and have negative thermal expansion coefficients.

Glass is strengthened by two methods: heat treating and chemical strengthening, where the glass is subjected to a special heat treatment and cooled, and tempered glass, which is made by heating annealed glass uniformly and cooling it faster than heat-strengthened glass. The main reasons to strengthen glass are to increase wind load, increase impact resistance, and combat thermal stress.

This is an update to a former description, on how to rotate screen and touchscreen in raspiOS.
