The transparent display panel 1120 may be implemented in various forms such as a transparent liquid crystal display (LCD) type, an organic light-emitting diode (OLED) type, a transparent thin-film electroluminescent panel (TFEL) type, a projection type, and the like. The transparent LCD type is a transparent display device implemented by using a pair of polarizing plates, an optical film, a transparent thin film transistor, a transparent electrode, and the like, by removing a backlight unit from an LCD device currently used. The transparent TFEL type is a device using an AC type inorganic thin film EL display (AC-TFEL) composed of a transparent electrode, an inorganic phosphor, and an insulating film. AC-TFEL is a display that emits light by exciting the phosphor as the accelerated electron passes inside the inorganic phosphor.

When the transparent display panel 1120 is implemented in a transparent TFEL type, the controller 4010 may adjust the information display position by adjusting an electron to be projected to an appropriate position. Since the inorganic phosphor and the insulating film have transparent characteristics, a very transparent display can be realized. In addition, the transparent OLED type is a transparent display device using an OLED capable of self-emission. Since the organic light emitting layer is transparent, when both electrodes are used as the transparent electrode, the organic light emitting layer can be implemented as a transparent display device.

When the transparent display panel 1120 is implemented in an LCD type, the transparent display panel 1120 may include a liquid crystal panel, a front polarizing film, and / or a rear polarizing film. The liquid crystal panel includes a pair of front and back substrates parallel and transparent to each other, and a liquid crystal layer formed therebetween. An electrode for applying an electrical signal in units of pixels is formed on the front substrate. When an electrical signal is applied to a specific pixel through an electrode, the liquid crystal that is twisted according to the liquid crystal type is unwound or vice versa. The front polarizing film and the rear polarizing film are attached to the front and back of the liquid crystal panel, respectively. The liquid crystal panel is configured to transmit various electrical information into visual information by using a change in liquid crystal transmittance according to an applied voltage. The liquid crystal panel is a color for displaying a bottom plate and a color in which a transparent thin film (TFT) transistor and a pixel electrode are arranged. It may be composed of a top plate composed of a filter and a transparent common electrode, and a liquid crystal filled between the two glass substrates. On both sides of the two glass substrates, polarizing plates which linearly display visible light (natural light) are attached. Due to the liquid crystal between the upper and lower electrodes, a capacitor and an auxiliary capacitor are formed to represent image information. The transparent thin film transistor is a transistor manufactured by replacing the opaque silicon of the conventional thin film transistor with a transparent material such as a transparent zinc oxide or titanium oxide, and forms a layer of a liquid crystal panel. Sources, gates, and drains may be provided in the transparent thin film transistor layer, and a plurality of transparent transistors are evenly distributed over the entire area of the display surface. Each of the transparent electrodes includes a plurality of line electrodes, and the alignment direction of the line electrodes is formed perpendicular to each other. For example, if the line electrodes of the first transparent electrode are arranged in the horizontal direction, the line electrodes of the second transparent electrode are arranged in the longitudinal direction. Accordingly, a plurality of intersecting regions are formed between the first transparent electrode and the second transparent electrode. Transparent thin film transistors are connected to each crossing area. Indium tin oxide (ITO) may be used as the transparent electrode, or a new material such as graphene may be used.

The backlight module 4020 may project light onto the transparent display panel 1120 such that the transparent display panel 1120 displays an image. In this case, when the transparent display panel 1120 does not emit light by itself, for example, an LCD, when the transparent display panel 1120 does not use the backlight module 4020, it is necessary to use ambient light such as natural light. This is a significant drop. The backlight module 4020 will be described in detail later.

The electromagnetic wave blocking module 4030 blocks electromagnetic waves generated from the transparent display panel 1120, thereby preventing electromagnetic waves from flowing into the crest 1010 and deteriorating the remains of the deceased. Detailed description of the electromagnetic wave blocking module 4030 will be described later.

The voice output unit 1080 may output a voice when the multimedia data received by the communication unit 1070 or stored in the data storage unit 4040 includes food data. The voice output unit 1080 may include a directional speaker. A directional speaker is a speaker that delivers sound only in a certain direction, and is classified into an array speaker, an ultrasonic speaker, and a dome speaker speaker according to an implementation method. In the array-type speaker, several omni speakers are arranged in series or in parallel, and the phase value of the acoustic signal inputted to each speaker is adjusted differently, thereby causing reinforcement and destructive interference between sound waves in the process of spreading sound waves into the air. To do that. This allows the acoustic signal to be heard only in certain directions, and in other areas or at very low sound pressure. In addition, this technique has the advantage of freely adjusting the direction of sound transmission by controlling the phase independently for individual speakers. The voice output unit 1080 may be arranged in a straight line by spacing the micro speakers at a predetermined distance to implement the directivity function by the dipole characteristic. Furthermore, by controlling the phase control and the sound pressure of two micro speakers arranged in a straight line differently from each other A directional speaker module having increased frontal directivity can be provided.

At this time, the settlement time information may represent the time at which the settlement of the ashes began. In addition, the communication unit 1070 may receive appropriate reference information regarding appropriate temperature, humidity, and illuminance according to the settling period of the ashes placed inside the ossuary 1010. At this time, the appropriate reference information indicates the information on the optimum temperature, humidity and roughness for preventing the deterioration of the ashes, the appropriate reference information may vary depending on the settlement period of the bones. At this time, the settlement period of the ashes may represent a period from the time when the ashes are cremated and contained in the ashes.

A detailed description of the operation of the power supply 1110 will be described later.

6 is a flowchart illustrating an operation of a power supply unit according to an embodiment of the present invention.

Referring to FIG. 6, the power controller 5040 may preset a first threshold power value, a second threshold power value, a first threshold voltage value, and / or a second threshold voltage value. When a radio wave signal is received through the radio wave signal reception module 5010 and the signal is converted into direct current power through the conversion module 5020, the reception power detection unit adjusts the magnitude (amount) of the converted received power (direct current power). In operation S6010, the charge amount detector detects the magnitude of the charging voltage of the power storage module 5030 to detect the amount of power charged in the power storage module 5030.

If the received power detected by the received power detector is greater than the first threshold power value, the power controller 5040 may supply the received power to both the transparent display device 1040 and the power storage module 5030 in operation S6020 and S6030. , S6040). However, if the received power is smaller than the first threshold power value, the received power may be compared with the second threshold power value (S6050). If the received power is greater than the second threshold power value, the power controller 5040 may supply the received power only to the transparent display device 1040 (S6060 and S6070). Furthermore, when the received power is smaller than the second threshold power value, the charging voltage detected by the charge amount detector may be compared with the first threshold voltage value (S6080).

If the charging voltage is greater than the first threshold voltage value, the power controller 5040 may supply the received power to the transparent display device 1040 and supply the charged power charged in the power storage module 5030 to the transparent display device 1040. There is (S6080, S6090, S6100). In addition, the power controller 5040 may compare the charging voltage with the second threshold voltage value from time to time, and when the charging voltage is greater than the second threshold voltage value, the power control unit 5040 may charge charging power charged in the power storage module 5030 to the transparent display device 1040. If the charging voltage is lower than the second threshold voltage value, the power controller 5040 stops supplying the charging power to the transparent display device 1040 and does not supply the received power to the transparent display device 1040. Instead, the power storage module 5030 may be charged by supplying only to the power storage module 5030 (S6110 and S6120). On the other hand, if the charging voltage is less than the first threshold voltage value, the power controller 5040 does not supply the received power to the transparent display device 1040 to supply only to the power storage module 5030 to charge the power storage module 5030. It can be made (S6130, S6140).

The first threshold power value and the second threshold power value set by the power controller 5040 may be set in consideration of the amount of operating power required for the transparent display device 1040 to operate. Accordingly, when the detected received power is sufficient to drive the transparent display device 1040 and charge the power storage module 5030, the power controller 5040 stores the received power in the transparent display device 1040 and the power storage. All may be supplied to the module 5030. At this time, by turning on both the switch 1 and the switch 2 in the circuit constituting the power supply 1110, the received power can be supplied to both the transparent display device 1040 and the power storage module 5030.

If the detected received power is sufficient to drive the transparent display device 1040 but insufficient to proceed to charging, the power controller 5040 may supply the received power only to the transparent display device 1040. In this case, by turning off the switch 1 and turning on the switch 2 in the circuit constituting the power supply 1110, the reception power may be supplied only to the transparent display device 1040.
