US 11,147,169 B2 · Impact absorbing element for display device

Abstract

A light-emitting device has improved impact resistance over conventional configurations. Such a light-emitting device includes a display panel layer, a housing layer, an impact absorbing layer adjacent the housing layer, a metal layer that is disposed between the impact absorbing layer and the display panel layer and that is deformable during an impact on the light-emitting device, and a compliant layer that is disposed between the metal layer and the display panel layer that enables a shape of the display panel layer to be maintained when the metal layer is deformed. Due to a compliance or low stiffness of the compliant layer, a permanent deformation of the metal layer due to an impact or device shape change is not discernibly transferred into the shape of the display panel layer, and the shape of the display panel layer is essentially maintained so that an impact or shape change does not adversely affect display performance.

Dependent claims

A light-emitting device comprising:

a display panel layer;
a housing layer;
an impact absorbing layer adjacent the housing layer;
a metal layer that is disposed between the impact absorbing layer and the display panel layer and that is permanently deformable during an impact on the light-emitting device;
and
a compliant layer that is disposed between the metal layer and the display panel layer and deforms by the permanent deformation of the metal layer, wherein when the metal layer is permanently deformed during the impact the compliant layer deforms such that the permanent deformation of the metal layer is not transferred to the display panel.
