Abstract
A method is presented for producing an optically transmissive layered structure for use as a display protector for electronic devices. The method comprises printing an ink pattern on a base layer, where said base layer is substantially optically transparent, and the base layer and ink are configured so that the ink reflects light with high incidence angle and transmits light with low incidence angle, when in use, thus displaying the pattern in the absence of light with high intensity and low incidence angle, the pattern becoming substantially undetectable otherwise.

A method for producing an optically transmissive layered structure for use as a display protector of a target entity, optionally electronic device, the method comprising:
- printing an optically transmissive ink pattern on a base layer, where said base layer is optically substantially transparent at predefined wavelengths preferably including visible light, and laminating the pattern-hosting base layer to a protective, preferably also optically substantially transparent, layer configured to face the environment of the electronic device, when installed thereon,
- wherein the base layer, protective layer and ink are configured so that the ink reflects, when in use, light with higher incidence angles more effectively, thus rendering the pattern more visible in the presence of light with higher incidence angles, and transmits light with lower incidence angles more effectively, thus displaying the pattern less clearly in the presence of light with lower incidence angles and preferably higher intensity.
An optical, optionally flexible, multilayer structure for use as a display protector for electronic devices, comprising a base layer, onto which an ink pattern has been provided, and a protective layer laminated thereon, where said base layer is substantially optically transparent, the base layer, protective layer and ink being configured so that said ink reflects, when in use, light with high incidence angle and transmits light with low incidence angle, thus displaying the pattern in the absence of light with high intensity and low incidence angle and presence of light with high intensity and high incidence angle, the pattern becoming substantially undetectable otherwise.
