OnScreen ® Hybrid glass anti-reflective surface
Protection Hybrid glass with matt surface
on Screen® Hybrid glass is a brand product of Neoxum GmbH
Antireflective hybrid glass is as hard as glass and yet as flexible as foil. OnScreen® hybrid glass with antireflective surface coating is an extremely resistant flexible composite of glass and special polymer. The glass-hard surface with anti-glare coating is combined with the flexibility of a film. The hard surface of 7H according to ISO 15184 guarantees efficient scratch protection of sensitive displays and surfaces. The flexibility to ensure that OnScreen ® hybrid glass does not splinter or break. Even mounting on smooth surfaces such as displays, glass, plastic or metal is child's play thanks to the homogeneous adhesive silicone adhesive layer. Bubble-free application is guaranteed. OnScreen ® hybrid glass can be removed at any time without leaving any residue. The adhesive effect is nevertheless enormously high, so that the flexible yet hard protective layer does not slip. Surfaces are protected from scratches and mechanical damage by means of a glass-hard anti-reflective layer. In our opinion, OnScreen® hybrid glass is superior to perfect scratch protection and fragile bulletproof glass. In addition to the anti-reflective version (designation MHG for frosted hybrid glass), there is our hybrid glass foil material as crystal clear variant (designation CHG for clear hybrid glass).
-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 even more 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® hybrid glass with anti-glare effect protects displays (and touchdisaplays!) from damage and scratches in cold to cold areas, e.g. outdoors in winter or in the frozen food industry. Under extremely hot conditions, such as industrial panels in heavy industry or surfaces that are permanently exposed to high temperatures, such as photovoltaic panels, OnScreen hybrid glass from Neoxum remains absolutely dimensionally stable. Also crystal clear hybrid glass shows an identical high temperature resistance.
Extreme Test OnScreen ® Hybrid Glass
In the following test (nothing was faked, retouched or manipulated!) we have a transparent hybrid glass The material is exposed to extreme flying sparks (heat) and subsequent mechanical stress (hammer blow). We could just as easily have used a matt anti-reflective hybrid glass.

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 advantage of not using an adhesive is that the adhesion is reversible and at the same time so strong that an applied hybrid glass - regardless of whether it is frosted or crystal clear - never slips or falls off under normal conditions. Neither cold nor high temperatures reduce the adhesion on smooth surfaces. Aging, as with acrylate adhesives, is not observed. OnScreen ® hybrid glass is perfectly suited for use in industry. Our hybrid glass does not splinter or break, so that even very special requirements, e.g. from the food industry or medical technology, can be met. We believe that our hybrid glass is superior to bulletproof glass.
But the flexible glass foils - in clear or anti-reflective versions - are also ideal as scratch protection for mobile phones, cameras and touch screens. Neoxum produces OnScreen ® hybrid glass 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. Individual engravings such as inventory numbers, names, logos or lettering are possible on top.
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.
OnScreen ® hybrid glass can be easily removed from all substrates without leaving any residue.
