The display panel 110 for entrance to a funeral hall having a natural light window effect according to an embodiment of the present invention is a display formed in the form of a window attached to the side of the entrance or the upper wall of the small entrance as shown in FIG. The unit 100 is formed in the form of a window on the display unit 100 and includes a display 110 that generates artificial natural light to irradiate the basement, and a control unit 200 that controls the display 110. .

The display unit 100 may further include a plate to which the display 110 is attached or a frame in the form of a frame surrounding to be positioned inside, and the frame is in any one of a square, a polygon including a rectangle, and a circle It is formed as, and is illustrated in a rectangular shape in FIG. 1, but this is not limited thereto. In addition, the frame is preferably made of wood or plastic.

The display 110 includes a Liquid Crystal Display, a Plasma Display Panel, an Electro Luminescent Display, Light Emitting Diodes (LEDs), and an organic light emitting diode ( Use any one of Organic Light Emitting Diodes, hereinafter, OLED). However, according to the recent development of light emitting device technology, it is preferable to use either the LED or the OLED.

LED is a semiconductor device that emits light when voltage is applied in the forward direction, and is a material that is replacing old-generation light bulbs and fluorescent lamps with longer lifespan and efficient power consumption than incandescent bulbs. In addition, the luminous color varies depending on the material used, and may include a device capable of emitting ultraviolet, visible, and infrared rays.

As an embodiment of combining the luminous colors of LEDs, white LEDs are manufactured by combining elements that emit red, green, and blue light, which are the three primary colors of light, to manufacture white LEDs, or by combining phosphors and blue LEDs, or zinc selenide (Zinc Selenide). selenide). If the LED is manufactured by targeting the wavelength layer of natural light using the same principle as described above, an artificial natural light LED having natural light as a luminous color can be manufactured.

OLEDs are similar to LEDs, but have a film of an emissive electroluminescent layer composed of organic molecules, and light is emitted when an electric current travels through the organic molecules.

In addition, OLED is a glass top plate, a cathode, which is an electrode charged to a cathode, an emission layer composed of organic molecules or polymers that transport electrons in the cathode layer, and holes in the anode layer. It is generally composed of a conductive layer, which is an organic molecule or a polymer that transports positive particles, an anode, which is a positive electrode, and a substrate, which is a glass bottom plate.

OLED emits light only when current is applied to the anode layer and the cathode layer. Electric current travels from the cathode layer through the emissive layer and the conductive layer, which is an organic material, to the anode layer, and the moving current provides electrons to the emissive layer and removes electrons from the conductive layer. As electrons are removed, the holes are formed in the conductive layer, and the holes jump from the conductive layer to the emission layer to recombine with electrons. When electrons combine with the holes, extra energy is released to emit light that can be seen through the substrate.

In addition, OLED is suitable for application to the display 110 of the present invention because it can combine all colors, has a wide viewing angle, low power consumption, and short response time.

The display unit 100 may create a cozy window atmosphere of a hanok by forming a grate 300, which is a pattern similar to the windows of a traditional hanok, on the front surface of the display unit 100 as shown in FIG. 2A or 2B. have.

The grate 300 is formed of wood, metal, paper, synthetic fiber, or synthetic resin, and when a sheet or the like is attached to the empty space between the grate 300 as a window paper, the display 110 emits sunlight. It is also possible to subtly illuminate through this window paper.

The LED module or OLED module constituting the display 110 is controlled by the control unit 200, and any one of visible light 350nm to 800nm, a short wavelength of 450nm to 480nm, and a color temperature of 3400K to 6800K. Emits a color corresponding to the range. Since the spectrum of natural light according to seasons or time zones is well dataized, by referring to this, inputting a set value to the control unit 200 and controlling it to be output to the display 110 can indicate a change in natural light on the ground from the basement.

More specifically, in the control unit 200 that controls the display 110, a solar power database is added to the control unit 200 so that the wavelength distribution of sunlight by season and time zone divided into 24 seasons, a short wavelength ratio, It is preferable to input color temperature information and set the display 110 to be controlled according to the season and time zone.

As an embodiment of simulating natural light in the display 110, blue light such as blue sky light is generated by adding a printed circuit board to which a thin nanoparticle coating simulating Rayleigh scattering is applied to an LED or OLED module forming the display 110. Can be copied.

In general, it is known that blue light is strongly emitted from a smartphone or computer screen, so it has been reported as an unhealthy light in the media. When the body is exposed to blue light, the secretion of serotonin, called the daytime hormone, is stimulated. Serotonin is a hormone that maintains the biological rhythms of the day and night, and is essential to the human body. When the human body is exposed to a smartphone or computer screen at night, the biological rhythm collapses and negatively affects the human body. Therefore, it should be understood that it is beneficial to the human body to simulate natural blue light in the display 110 that irradiates artificial natural light underground from sunrise to sunset.

As shown in Fig. 4, the present invention may further include a decoration part 400 in addition to the grate 300 formed in a pattern similar to a window of a traditional hanok in the display part 100, and the decoration part Alternatively, it may further include a water pipe 410 through which the stem of the plant can be inserted.

It consists of a vent 413 formed as a hole in. In more detail with respect to the shape of the water pipe 410, the insertion hole 411 is formed as a front portion formed of an arc, and the pedestal 412 is bent in a horizontal direction from the front portion of the insertion hole 411. It is formed, and the support 412 is formed in a form in which the other end of one end where the insertion hole 411 is located is in contact with the grate 300 and is attached thereto.

Flowers or plants inserted in the water tube 410 are exposed to artificial natural light irradiated from the display 110, as shown in FIG. 4B. Fluorescent lamps are installed in the basement of existing funeral homes, and it has been studied that photosynthesis of plants becomes more active under natural light than fluorescent lamps (Juyun Lee, Jongyoung Lee, Seungwon Han, Gyudong Song. (2007). Effect on the chlorophyll content. Journal of the Korean Institute of Architectural Environments, 1(1), 14-20.). Therefore, the flowers or plants arranged in the water pipe 410 can maintain their vitality for a long time, and can contribute to supplying oxygen in the basement even though it is a small amount.

In addition, since the pedestal 412 has a space capable of storing an appropriate amount of water, the pedestal 412 can maintain a certain water level in the pedestal 412 to keep flowers or plants fresh. In order to maintain a certain water level inside the pedestal 412, the material of the pedestal 412 is preferably a transparent plastic material.

As shown in Fig. 3, by using the display 110 as a monitor of a personal computer, and using the control unit 200 as a main body of the personal computer, natural light or a screen selected by the user is selected for the display 110. Can be sent out. In more detail, it is possible to install and execute an image program, a slide show program, or a moving picture program in the control unit 200, and reproduce an image or video desired by the survivors.

In another embodiment of the present invention, as shown in FIG. 5, a display panel for entrance to a funeral hall having a natural light effect of collecting natural light from the ground and transmitting it to the basement and irradiating natural light to the basement through the display 110 is provided.

In another configuration of the present invention as described above, a light collecting unit 1100 for collecting natural light from the ground, a reflecting unit 1200 for sending natural light collected from the light collecting unit 1100 to the basement, and a panel for receiving natural light and irradiating it to the basement Includes part 1300.

The condensing part 1100 is composed of a condensing member installed on the ground to condense natural light from the ground, and is installed on the upper end of the reflecting part 1200. The condensing unit 1100 may also use a fixed condensing plate, but it is preferable to be configured as a variable condensing plate so that the condensing position can be changed according to the altitude of natural light that changes according to seasons and time periods. To this end, a control device for controlling the condensing unit 1100 may be further included to control a rotating member included when the condensing unit 1100 is formed of a variable condensing plate to change the condensing position.

The reflective part 1200 is coupled to the lower surface of the light condensing part 1100 and is formed in the shape of a tube extending to the panel part 1300 located underground. It is preferable that the reflective member in the reflective part 1200 is formed of a reflective plate made of a mirror material capable of reflecting natural light.

The panel unit 1300 is composed of a panel 1400 having a function of selectively displaying natural light or a screen desired by a user, and the panel may be made of a panel 1410 having a variable transmittance. The variable transmittance panel 1410 is composed of a variable transmittance film 1412 and a transparent display 1411 having a shape in which objects from the rear can be seen because the area of the panel is transparent, and the transparent display 1411 includes a HUD, HMD, and LCD. Or it is composed of OLED, etc.

Among the transparent displays 1411, an OLED transparent display is an emissive type display, in which a light emitting layer is positioned between a cathode and an anode. Since the energy emitted by the organic material used in the light emitting layer exists in a region greater than the energy of visible light, it is formed to be generally transparent. Therefore, if the cathode and the anode are used as transparent materials, a transparent OLED display can be implemented. In general, it is manufactured by using ITO (Indium Tin Oxdie) for the positive electrode and aluminum for the negative electrode, but it is possible to secure transmittance by using thinly cast metal such as silver.

When the transparent display 1411 is set as a monitor of a personal computer, and the main body of the personal computer is connected as a control device capable of controlling the transparent display 1411, during a time period after sunset where natural light cannot be transmitted from the ground to the basement. It is possible to transmit any one of artificial natural light, an image, a slide show, and a video desired by the user to the transparent display 1411.

If the transmittance variable film 1412 is further included on the rear surface of the transparent display 1411 connected to the reflector 1200, artificial natural light and image desired by the user even in the time period between sunrise and sunset when natural light is transmitted from the ground to the basement. , Slideshow, and video can be transmitted.

It includes a micro space between the lower electrodes, the ink containing colored charged particles is accommodated in the micro space, and an ink receiving layer is further included between the upper electrode and the lower electrode.

The transmittance of the variable transmittance film 1412 is changed according to whether a voltage is applied to the upper electrode and the lower electrode. When a voltage is applied to the variable transmittance film 1412, an electric field is generated and the conductive material layer has an electric charge. In this case, when a voltage is applied, the colored charged particles have a charge opposite to that of the conductive material layer, thereby generating an electric attraction between the colored charged particles and the conductive material layer.

As the colored charged particles move to the top of the conductive material layer, the area occupied by the colored charged particles in a cross section perpendicular to the direction in which light is incident from the variable transmittance film 1412 is reduced, and thus the colored charged particles The light blockage by this decreases and the light transmittance increases.

As a material of a transparent film surrounding the outside of the variable transmittance film 1412, polyethylene terephthalate (PET), polyethylenenaphthalate (PEN), polyethersulfone (PES), polycarbonate (PC), polypropylene (PP), polyimide (PI), cycloolefin aerial It is preferable to prepare a resin containing any one or more of a coalescence and a norbornene-based resin. In addition, the thickness of the transparent film is preferably formed in the 50㎛ 500㎛.

The conductive material layer is preferably prepared by including at least one of indium tin oxide, zinc oxide, zinc oxide, graphene, carbon nanotubes, fluorine-doped tin oxide, silver nanowires, metals, and conductive polymers.

The colored charged particles are metal particles including elements such as aluminum, copper, silver, silicon, carbon, iron, nickel, gold, titanium, zinc, zirconium, tungsten, and combinations thereof, polystyrene, polypropylene, polyvinyl chloride, It is preferable to use a polymer particle such as polyethylene or polypropylene, and a metal or conductive material of any one of carbon black.

The variable transmittance film 1412 further includes a power supply unit to allow the user to directly supply or stop power, and may change a clear state with a transmittance of 40% to 70% or a dark state with a transmittance of 0%.

In addition, it is possible to further include a control unit of the transmittance variable film 1412 to control the clear state or the dark state at a time period selected by the user, and the user can control the panel unit 1300 to provide artificial natural light, images, slide shows, and When any one of the moving pictures is transmitted, it is also possible to set the variable transmittance film 1412 to be automatically converted to the dark state.

As shown in FIG. 6, a photovoltaic device for generating solar power may be further included in the condensing unit 1100 to supply power to the panel unit 1300. Since the light collecting unit 1100 is installed at a location with the highest amount of sunlight in a corresponding building, it has high power generation efficiency when the photovoltaic device is installed. The solar power generation device directly transmits power through a power cable 1210 that transmits power to the panel unit 1300, and when the panel unit 1300 does not use power, a battery that stores power It can be used as emergency power, including more.
