Abstract
A multi-segment display is disclosed. Specifically, a low height LED-based display is disclosed that includes a number of segments. The segment construction may include a Printed Circuit Board (PCB) layer, a first substrate, and a second substrate that are laminated or otherwise connected to one another. The first and second substrates may include windows which allow light generated by a light source mounted on the PCB to exit the display and one or more of the windows may be filled with an encapsulant.
Claims20
A display assembly, comprising:
- one or more display segments, the one or more display segments comprising:
- a light source mounted on a first major surface of a third substrate and configured to generate and emit light away from the third substrate;
- a second substrate comprising a first major surface and a second major surface, the second substrate having an opening window that extends from its first major to its second major surface, wherein the opening window is configured to surround the light source, and wherein the second major surface of the second substrate is positioned proximate to the first major surface of the third substrate;
- a first substrate comprising a first major surface and a second major surface, the first substrate having an opening window that extends from its first major surface to its second major surface, wherein the opening window of the first substrate is positioned to coincide with the opening window of the second substrate such that light emitted by the light source passes through the opening windows of both the first substrate and the second substrate, and wherein the second major surface of the first substrate is positioned proximate to the first major surface of the second substrate.
A multi-segment display, comprising:
- a plurality of segments, at least one of the plurality of segments comprising:
- a first substrate, a second substrate, and a third substrate, wherein the first and second substrates each comprise opening windows, wherein the opening window of the first substrate is filled with an encapsulant, wherein the opening window of the second substrate is empty, and wherein the first substrate, second substrate, and third substrate are bonded to one another such that a hermetically-sealed cavity is created between the third substrate, the encapsulant, and walls of the second substrate that surround the opening window of the second substrate.
A panel of multi-segment displays, comprising:
- a first substrate, a second substrate, and a third substrate, wherein the first and second substrates each comprise a plurality of opening windows, wherein the opening windows of the first substrate are filled with an encapsulant, wherein the opening windows of the second substrate are empty, and wherein the first substrate, second substrate, and third substrate are bonded to one another such that a plurality of hermetically-sealed cavities are created between the third substrate, the encapsulant, and walls of the second substrate that surround the opening windows of the second substrate.
