Abstract:
To provide an LED (light emitting diode) module which is miniaturized and whose productivity is high and an LED display device.
This LED module with a microcomputer is provided with a printed circuit board 2, an LED lamp 3 which is mounted on the surface of the printed circuit board 2 and a microcomputer chip 4 which is mounted on the back of the printed circuit board 2 and has the built-in drive circuit of the LED lamp 3 to thereby control the lighting of the LED lamp 3.
