Abstract
A display panel including a translucent carrier element that has an inner side, an outer side, and a display area is provided. At least one display element is arranged within the display area, the display element being formed by geometric structures realized as protrusions and/or depressions on both of the inner side and the outer side of the translucent carrier element. The display panel can be used in an information display that in particular comprises at least a light emitting element for backlighting the display element. The information display can be used in an appliance such as an electric toothbrush, wherein the protrusions and/or depressions integrally formed with the translucent carrier element.
Claims19
A display panel for a hand-held electronic appliance, comprising:
- a translucent carrier element that has an inner side, an outer side and a display area, wherein the translucent carrier element is configured to comprise a housing part of the hand-held electronic appliance having at least one light-emitting element arranged inside the hand-held electronic appliance;
- and
- at least one display element arranged within the display area to be lit during selective activation of the at least one light-emitting element to allow a user to visualize various operating states of the hand-held electronic appliance, the display element being formed by geometric structures realized as protrusions and/or depressions on both of the inner side and the outer side of the translucent carrier element, wherein the protrusions and/or depressions are integrally formed with the translucent carrier element to cause variations in light intensity within the geometric structures, the geometric structures having differential thicknesses such that a portion of a relatively low thickness within the geometric structures causes a relatively higher illumination of the translucent carrier element within the geometric structures, and a portion of relatively high thickness within the geometric structures causes a relatively lower illumination of the translucent carrier element within the geometric structures, wherein at least some of the protrusions and/or depressions on both of the inner side and the outer side of the translucent carrier element are essentially congruent, wherein at least one of said congruent protrusions and/or depressions on one of said inner and outer sides is slightly smaller than the corresponding protrusion and/or depression on the other side, so that when the at least one light-emitting element arranged inside the hand-held electronic appliance is lit, light scattering in said congruent protrusions and/or depressions occur, which leads to a halo effect therein.
