Abstract
An LED display module contains a substrate, and an array of light emitting devices arranged in rows and columns on a substrate. Each light emitting device has a LED chip electrically connected to contact pads on the substrate, a black resin portion covering around the contact pad, and a transparent resin portion molded around the LED chip and the black resin portion. By forming the black resin portion around each metal pad, the LED display module provides an increased contrast ratio for the display surface.
