Abstract
An LED display module having features for improvement over prior art devices by providing novel features for improved LED visibility, improved weather and climatological sealing, improved electromagnetic interference (EMI) suppression, improved heat dissipation, and improved airflow.
Claims19
An LED display module comprising:
- at least one display assembly, the at least one display assembly including:
- a printed circuit board having a plurality of spaced LED packages, each LED package including one or more LEDS, coupled on a first major surface of said printed circuit board,
- a louver panel adjacent the plurality of LED packages, the louver panel including a support grid having a plurality of overmold cavity view ports projecting from the support grid, each of the plurality of overmold cavity view ports is in respective alignment with each of the plurality of LED packages and each overmold cavity viewport covers and isolates a respective LED package and allows viewing of the respective covered LED package through the overmold cavity view port, and
- a frame sealed to the louver panel with the printed circuit board and plurality of LED packages correspondingly sealed therebetween.
