Abstract
A light emitting diode (LED) display module includes an array of surface-mount devices (SMDs) arranged in rows and columns on a substrate. Each SMD has red, green, and blue LED chips connected to the substrate and a first transparent resin portion molded around the LED chips; a black resin portion molded around each SMD in a manner to fill spaces between SMDs so as to block light emitted from a sidewall of each SMD; and a second transparent resin portion molded on the first transparent resin portion and the black resin portion.

A light emitting diode (LED) display module, comprising:
- an array of surface-mount devices (SMDs) arranged in rows and columns on a substrate, each SMD comprising red, green, and blue LED chips connected to the substrate, and a first transparent resin portion molded around the LED chips;
- a black resin portion molded around each SMD in a manner to fill spaces between SMDs so as to block light emitted from a sidewall of each SMD;
- and
- a second transparent resin portion molded on the first transparent resin portion and the black resin portion.
A light emitting diode (LED) display module, comprising:
- an array of surface-mount devices (SMDs) arranged in a matrix on a substrate, each SMD comprising red, green and blue LED chips, a black side wall defining a cavity, and a first transparent resin portion molded in the cavity;
- and
- a second transparent resin portion molded on the first transparent resin portion and molded around each SMD in a manner to fill spaces between SMDs.
A method for fabricating a light emitting diode (LED) display module, the method comprising:
- providing an array of surface-mount devices (SMDs) arranged in a matrix on a substrate, each SMD comprising red, green and blue LED chips connected to the substrate and a first transparent resin portion molded around the LED chips;
- forming a black resin portion molded around each SMD in a manner to fill spaces between SMDs so as to block light emitted from a sidewall of each SMD;
- and
- forming a second transparent resin portion on the first transparent resin portion and the black resin portion.
