In general, in order to provide a unique design to other articles such as wigs, clothes, jewelry, and devices, and to fingernails of the body, another device capable of emitting light by applying nail polish or the like is attached to other marks or fingernails, thereby highlighting the corresponding portion.

In addition, the jewelry includes a ring, an earring, a necklace, a bracelet, a glove, a watch, a headband, an artificial nail, a wig, a hat, etc., and the jewelry used as a portable article includes an umbrella, a parasol, a beauty product, a fan, a bag (a bag), a towel, a belt, etc.

Further, in the case of conventional jewelry, specific devices, parts of the body, interior articles, and other devices constituting LEDs emitting light, since the technology of displaying a plurality of colors is generally performed by a single color, there are problems that a plurality of Light Emitting Diodes (LEDs) are required to display a plurality of colors, and that frequent replacement of batteries or charging is required due to a large power loss, and that economical efficiency is very low, and that a large amount of batteries are consumed.

In view of this problem, recently, a light emitting system using a micro light emitting diode having high power consumption and high light brightness has a high call sound, and the micro light emitting diode is applied to various fields and is configured in various articles and devices.

The wireless transmission/reception method between the main device unit 400 and the smart phone 600 can also use a visible light wireless communication (Li-Fi) technology that uses the wavelength of light emitted from the light emitting diode to realize a fast communication speed, and particularly, when the micro light emitting diode technology of the present invention is applied, the effects of miniaturization and weight reduction of parts are improved.

That is, in the smartphone 600 of the present invention, the design and the color change are controlled and changed by the short-range remote control between the transparent micro-display skin 300 and the smartphone 600 in any one of the structures of the specific device 10, the specific article 20, and the body part 30, and the main element unit 400 is wirelessly connected to the smartphone 600 by the short-range wireless communication method such as bluetooth communication, WIFI communication, NFC communication, IR communication, and visible light wireless communication, and when the user selectively controls the application program included in the smartphone 600, the transparent micro-light-emitting diode display skin 300 is made to show various colors by the control command.

In addition, when the transparent micro-led display skin 300 is run by the application program of the smart phone 600 controlling the master unit 400 and the remote slave unit 500 according to the present invention, the master unit 400 runs the transparent micro-led display skin 300 when the initial control command is transmitted to the master unit 400, and when the distance between the master unit 400 and the specific transparent micro-led display skin 300 becomes longer, the control command is transmitted to the remote slave unit 500, and the remote slave unit 500 runs the corresponding transparent micro-led display skin 300.

That is, when the specific transparent micro-led display skin 300 is initially operated by the smartphone 600, the master unit 400 or the remote slave unit 500, which is close to the specific transparent micro-led display skin 300 in distance, operates the specific transparent micro-led display skin 300, which has an advantage of being able to control quickly and accurately.

According to the selectively controllable micro light emitting diode system of the present invention, it is possible to easily attach and form a micro light emitting diode display skin to a specific device, a specific article, a part of a body, etc., and it is possible to apply the system to various fields, thereby providing variety of use, and in addition, it is convenient to control through a smart phone which a user often holds, thereby providing convenience of use, and it is easy to change overall or local multi-colors and flashing according to the purpose of use, thereby being capable of instantly responding to a field situation, arousing interest and satisfaction of the user, and having an effect of enabling long-term use through a low-power and charged battery and overall power supply.
