on Screen ® Hybrid Glass
Protective effect Hybrid glass
on Screen® Hybrid glass is a brand product of Neoxum GmbH
OnScreen® Hybrid Glass is an extremely resistant flexible composite of glass and special polymer with the flexibility of a film combined with the hard surface of glass. The hard surface of 7H according to ISO 15184 guarantees efficient scratch protection of sensitive displays and surfaces. OnScreen® hybrid glass is the perfect combination of the properties of transparent glass and the flexibility of plastic film. The result is a very flexible, bendable and transparent surface protection that has a glass-hard surface and is still elastic enough not to shatter like glass. Equipped with a thin silicone layer, hybrid glass foils adhere perfectly to all smooth surfaces made of plastic, glass or metal without leaving any residue on subsequent removal. Touch surfaces are effectively protected from scratches and mechanical damage. In our opinion, OnScreen® hybrid glass is superior to perfect scratch protection and fragile bulletproof glass.
High transparency onscreen ® Hybrid Glass
OnScreen ® hybrid glass is very strong with 0.216 mm and therefore extremely robust. Nevertheless, the flexible glass is highly transparent and crystal clear. Screen contents are displayed true to life.
If an application on the display in direct sunlight is no longer readable or can no longer be read at all, we recommend the use of the Robust anti-reflective hybrid glass with matt surface coating.
Measurement data Transparency
The light transmission was determined according to ASTM D 1003. The measurement data show a transparency of up to 95%, which means that the human eye can detect virtually no difference with or without hybrid glass in terms of light transmittance. Just Glass!
Optical properties OnScreen ® hybrid glass
The colour fastness of OnScreen® hybrid glass is enormously high. An essential property of glass is its light transmittance in the spectrum that is optically visible to humans, i.e. about 400 to 800 nanometers. In addition, glass has excellent colour fastness properties. Due to the amorphous structure of glass, which is combined with a highly transparent special polymer, an extremely high colour fidelity is achieved: colours of the screen or display or touch screen are completely retained and are not falsified or the colour spectrum shifted. Feedback from our customers in the field of photography or graphics confirms the outstanding optical properties. Customers from the industrial environment who use the very hard surface and flexibility of hybrid glass, for example in their production on touch screens, panels or terminals, are also convinced of the colour fastness.
-30 °C to 140 °C
High temperature resistance
Both the Antiblendfolie as well as the crystal clear display foil from Neoxum are extremely temperature resistant. OnScreen ® hybrid glass is also very temperature resistant. Tests have shown that the flexible and glass-hard display protection material is stable within a temperature range of -30 °C to +140 °C. OnScreen® industrial grade hybrid glass protects sensitive displays in cold areas, such as outdoor, as well as hot conditions, such as industrial panels in steel production or the printing industry. Neoxum OnScreen® hybrid glass remains absolutely dimensionally stable at high temperatures or low temperatures. The flexible and crystal-clear non-shattering alternative to bulletproof glass retains its high transparency and does not become cloudy even after many loads.
Extreme Test OnScreen ® Hybrid Glass
Heat test with a cut-off grinder (flex) that grinds off a metal block. The OnScreenhybrid glass can withstand extreme flying sparks. Subsequent extreme test with a hammer blow on the hybrid glass, which was applied to a Plexiglas carrier.

Adhesion Effect Display protection Neoxum
OnScreen ® hybrid glass adhesive effect
Analogous to our Anti-reflex screen protection films Or Crystal clear Screen Protection films OnScreen ® hybrid glasses adhere exclusively via physical adhesion forces. The siliconized underside of the hybrid glass adheres to smooth surfaces such as glass, plastics, polished metals and painted surfaces with the help of a kind of suction foot in the nanometer range. The absence of adhesive has the advantage that the adhesion is reversible and at the same time so strong that an applied hybrid glass never slips under normal conditions. Neither cold nor high temperatures reduce the adhesion on smooth surfaces. Aging, as with acrylate adhesives, is not observed. OnScreen ® hybrid glasses are perfectly suited for use in industry. But the flexible glass foils are also suitable as scratch protection for mobile phones, cameras and touch screens. Neoxum produces OnScreen ® hybrid glasses up to a size of 1000 x 800 mm (approx. 55 inch diagonal) in almost any shape (very tight radii have to be tested in advance) and quantity to customer specifications.
Adhesion/Adhesive Strength Neoxum Display protection
Adhesion forces on surfaces
Neoxum display protection films and our OnScreen ® hybrid glass adhere purely via physical adhesion, i.e. the films adhere to the display via a kind of "suction foot in the nanometer range", without using any adhesives. When Neoxum Display Protector films or hybrid glass are removed from the display, no residue remains on the display.
Physical chemical forces
More specifically, several physico-chemical forces play a role. Adhesion is a fundamental phenomenon in the molecular area caused by polar interactions at interfaces, in our case the interface surface of the display <–>–> Silicone adhesive layer of the Neoxum display film, or OnScreen ® hybrid glass, so-called Van-der-Waals bonds between molecules of the display surface and molecules of the adhesive layer (the very thin silicone adhesive layer). The decisive factor in adhesion is the spatial proximity of the two surfaces. The silicone adhesion layer of Neoxum display protection, or surface protection, is designed in such a way that our display films, as well as our hybrid glass, adhere very well to many smooth materials such as plastics, metals and glass. The adhesion film and the hybrid glass can be removed from all material types without leaving any residue.
Layer structure OnScreen ® Hybrid glass
Why is that
Commercially available simple adhesive films usually have an adhesive layer of acrylate adhesive or modified acrylate. This adhesive layer practises much stronger physical bonds, which are much stronger than the adhesive forces of the adhesive films. This type of acrylate adhesive film can usually NOT be removed after a few weeks or months of use without leaving any residue on the display.
The OnScreen ® hybrid glass can be easily removed from all substrates without leaving any residue.
