Abstract

A video display module comprises a circuit board having a front face, a plurality of light-emitting elements electrically coupled to the front face of the circuit board, and a polymer encapsulating member adhered to the front face of the circuit board, the polymer encapsulating member substantially covering at least a portion of the circuit board and a portion of the plurality of light-emitting elements, the polymer encapsulating member substantially sealing the portion of the circuit board and the portion of the plurality of light-emitting elements.

Claims

1. A video display module comprising:
