The flexible display layer mounting unit 110 attaches a flexible display layer unit to the front surface of the flexible display layer mounting unit 110,

It is constructed by selecting either the guide rail structure or the adhesive coating structure.

The magnetic contact part 120 serves to detachably attach the magnet to the N and S poles of the upper surface, the lower surface, the left surface, and the right side of the flexible display layer mounting part with another neighboring display layer support.

The sensing sensor unit 130 senses that another neighboring display layer support is coupled to one side of the magnetic contact unit.

It consists of a touch sensor.

The middle power supply unit 140 is disposed on one side of the rear side and receives power from the main power supply unit to supply power to the flexible display layer and the sensing sensor unit from the main power unit, .

The display layer support comprises a cylindrical box, a triangular box, a rectangular box, a square box, a square box, and an arcuate box, the size of which is 3 cm * 3 cm * 3 cm, 5 cm * 5 cm * 5 cm, * 10cm, 15cm * 15cm * 15cm, 20cm * 20cm * 20cm, 30 * 30cm * 30cm, 5cm * 3cm * 3cm, 10cm * 5cm * 5cm, 15cm * 5cm * 5cm, 20cm * 5cm * 5cm, .

The TFT backplane 220 is located on the PI substrate, and TFT elements, metal wires, and an insulating film for driving each pixel of the display are formed.

The organic light emitting layer 230 is positioned on a TFT backplane and when the holes and electrons are injected from a cathode and an anode,

The encapsulation layer 240 is positioned on the organic light emitting layer part to protect the organic light emitting layer part and the TFT backplane part and to prevent water from penetrating.

The manufacturing process of the flexible display layer portion is as follows.

That is, a PI substrate, a TFT backplane, an organic light emitting layer, and a coating layer are formed, and then a carrier glass is removed.

First, as shown in Fig. 7, a PI substrate is formed.

The core of flexible display production technology is to secure a substrate material that can be processed at a high temperature while having flexibility. Currently, PI material, which does not cause glass transition phenomenon even at a temperature of 300 ° C or higher among plastic materials, is used.

Here, the PI material is made of a PI material having a transmittance of 90%. Since the PI material is easily warped and shrinks and expands due to heat larger than the glass substrate, the substrate is fixed to the carrier glass.

Next, the liquid PI material is thinly coated on the carrier glass and then cured to form the TFT backplane and the organic light emitting layer on the substrate, and then the product is separated from the carrier glass by the laser lift off method.

Here, in order to form a TFT backplane, various processes such as vacuum deposition, exposure, and etching are performed. Among them, there is a high temperature process of 300 ° C or more, and a material having a low glass transition temperature is configured to be impossible to use.

Then, an encapsulating layer is formed.

The organic light emitting layer is vulnerable to moisture, and it is necessary to form an encapsulating layer to prevent moisture penetration. In the flexible display, TFE (Thin Film Encapsulation) technology which improves the water permeation prevention performance while securing flexibility is used.

Finally, a hard coated portion is formed.

The hard coating portion protects and supports the organic light emitting layer portion, the TFT backplane portion, and the PI substrate portion from external pressure.

The Bluetooth communication unit 410 performs low power wireless connection at a very short distance within 10 meters to exchange information.

It uses the Industrial Scientific and Medical (ISM) frequency band of 2400 to 2483.5 MHz. In order to prevent the interference of other systems that use the upper and lower frequencies, we use a total of 79 channels, ranging from 2400MHz to 2MHz and 2483.5MHz to 3.5MHz, except 2402 ~ 2480MHz.

In addition, in order to eliminate interference between systems, a frequency hopping scheme is used.

Frequency hopping is a technique for rapidly moving a large number of channels according to a specific pattern and transmitting packets (data) little by little. In the present invention, 79 channels are configured to hop 1600 times per second.

The Zigbee communication unit 420 provides a data rate of 250 kbps toward a smart device located near (10 m to 75 m) using a frequency band of 2.4 GHz.
