We all know the effect: Wherever you encounter a display, you almost automatically assume it has a touch screen. This is obvious, because nowadays new TFT solutions are very rarely equipped without a touch panel. From resistive touch panel (RTP, via pressure) to capacitive touch panel (PCAP, via conductivity), there are various possibilities.

There are basically two different types of cover lens material: glass and plastic. The decisive factor in deciding between the two materials is usually the desired hardness. Nowadays, glass cover lenses are mostly used due to various factors, which is why they are also called cover lenses.

LCD displays are found in many areas of everyday life, from smartphones and tablets to televisions and monitors. An important component of an LCD display is the cover lens, which protects an LCD from damage and improves colour reproduction. In recent years, two printing processes have become established for printing LCD cover lenses: organic printing and ceramic printing. In this blog post, these two printing methods will be described in detail and compared. The limitations of each printing process in terms of material, size and application area will also be considered.
