End-wall frame for led alphanumeric display |
摘要 |
An end-wall frame for an LED alphanumeric display circuit board provides full-length accurate standoffs for the display to prevent cracking and crazing of the epoxy coating of the encapsulated device, eliminates the need to apply black paint to the non-display portions of the lens, and provides a device for accurately aligning the printed circuit board in the lensed area.
