In addition, the light bulb generates a lot of heat, power consumption also had a lot of disadvantages and switching speed was also a problem.

In order to solve such a problem, a display board in which light emitting diodes are arranged in a panel of a predetermined size is applied, but various colors are available, but manufacturing cost is high, manufacturing time is long, and a device for control has a complicated problem.

Therefore, the present invention is an all-optical display device, which arranges bulbs in which a plurality of light emitting diodes are combined to a predetermined standard, significantly reducing production period and cost while displaying various colors, and at the same time, various functions for various advertisements at the same time. An object of the present invention is to provide a display device using a light emitting diode capable of producing color light.

In addition, it is intended to replace the advertising signboard in a commercial district or residential district, or to be applied to various fields such as decoration or interior use.
