The composite sensing signal receiving unit 210 receives various sensing data (such as environmental change sensing data, human sensing data, and the like) sensed by various sensing sensors (not shown) installed on the surface of the environmentally friendly window device 100, And transmits the digital signal to the composite controller 260.

The light shielding controller 240 changes the arrangement of the liquid crystal 242 between the ITO films 241 by applying a voltage to the light shielding controller 240a and instantaneously changes the opaque state to the transparent state And it is possible to freely change the transparency according to the change of the voltage as shown in FIG. 4B.

For example, the bar-shaped liquid crystal 242 aligns along the inner wall of the capsule when no voltage is applied to the shading regulator 240a.

In this state, the light incident on the shading regulator 240a is refracted on the capsule surface or inside due to the difference in refractive index between the polymer and the liquid crystal and the birefringence of the liquid crystal. As a result, the light does not go straight and is scattered and appears opaque. (See FIG. 4A)

In contrast, when a voltage is applied to the light-shielding device 240a, the liquid crystal 242 is arranged in a direction perpendicular to the electrode due to the property of being parallel to the direction in which the voltage is applied.

When the liquid crystal having the refractive index coincides with the refractive index of the polymer in such an arrangement state is the same as the absence of the interface of the capsule, the light is straightened without scattering, so that the shading regulator 240a appears transparent.

4B, due to the structure and function of the light-shielding device 240a as described above, it is possible to divide the region of the window glass into a plurality of regions along the vertical direction and the lateral direction to implement selective control in a transparent or opaque state do.

The low radiation coating (c10) is a multilayer thin film structure based on a low radiation layer (c50) that selectively reflect far infrared rays among the solar radiation and has a low emissivity effect on the low radiation coating (c10) Thereby providing an excellent heat insulating performance.

For example, when a low-emission coating (c10) is applied to a window glass coating, it minimizes the movement of heat between indoor and outdoor by reflecting outdoor solar radiation in summer and preserving indoor heating radiation in winter. Bring it.

Herein, the term 'emissivity' means a rate at which an object absorbs, transmits, and reflects energy having a specific wavelength. In the present invention, the emissivity represents a degree of absorption of infrared energy in an infrared wavelength range, Specifically, it means the ratio of infrared energy absorbed to the applied infrared energy when a far infrared ray corresponding to a wavelength range of about 5 탆 to about 50 탆 is applied, which shows a strong heat action.

The thickness of the low emissivity layer (c50) may be, for example, from about 5 nm to about 25 nm, and the low emissivity layer (c50) having the thickness of the above range can simultaneously achieve low infrared emissivity and high visible light transmittance Suitable.

The low radiation protection layers c40 and c60 are made of a metal having excellent light absorption performance and function to adjust sunlight and control the color realized by the low radiation coating c10 by adjusting the material, .

The low radiation protection layers c40 and c60 absorb a certain portion of the visible light rays using the metal having the extinction coefficient of the visible light region in the above range so that the low radiation coating c10 has a predetermined color.

For example, the low radiation protection layer (c40, c60) may include at least one selected from the group consisting of Ni, Cr, an alloy of Ni and Cr, and combinations thereof, but is not limited thereto.

The dielectric layers c30 and c70 can function as an oxidation preventing layer of the low emission layer c50 because the metal used as the low emission layer c50 is generally well oxidized and the dielectric layers c30 and c70 can function as an anti- It also serves to increase the transmittance.

Also, the optical performance of the low spin coating (c10) can be controlled by suitably adjusting the material and physical properties of the dielectric layers (c30, c70).

The lowermost barrier layer (c20) can be used to protect the window glass from heat in the heat treatment process during the manufacturing process of the window glass, to protect it from a high temperature and high humidity environment when left in a hot and humid environment, For the purpose of protection against.

The lowermost barrier layer c20 is formed in a multi-layer structure including at least a first layer c21 and a second layer c22 in order to achieve the purpose of protecting the low radiation coating c10.

The first layer c21 may comprise a metal or a composite metal. More specifically, the metal may be Si, Zr or Ti, and the composite metal may be SiAl, ZrSi or TiZr.

The second layer c22 includes one selected from the group consisting of a metal oxide, a metal nitride, a metal oxynitride, a complex metal oxide, a complex metal nitride, a complex metal oxynitride, and combinations thereof.

The first layer c21 may be formed of a metal or a composite metal to mainly contribute to the prevention of diffusion of alkali ions and oxygen from the transparent glass substrate g10 and the second layer c22 may be an oxide of a metal or a composite metal, Oxynitride or nitride and can mainly contribute to the improvement of the interfacial adhesion between the transparent glass substrate g10 and the low-emission coating c10.

The first layer c21 and the second layer c22 may be formed to have a thickness suitable for each application. For example, the first layer c21 may be formed to a thickness of about 0.5 nm to about 5 nm , And the second layer (c22) may be formed to a thickness of about 0.5 nm to about 50 nm.

The current measuring unit 252 measures the current flowing through the heating glass 1 supplied with electric power from the power supply unit 256. The current measuring unit 252 can measure a current flowing through the heating glass 1, It is preferable to measure the current flowing through the heating glass 1 on one path of a wire to which the power supply unit 256 and the heating glass 1 are connected rather than being directly placed on or attached to the heating glass 1 .

The resistance measuring unit 253 is a component for measuring the internal resistance of the heating glass 1. The resistance measuring unit 253 receives the voltage value applied to the heating glass 1 from the power supply unit 256, The internal resistance of the heating glass 1 is calculated.

In this case, the value of the current can be calculated by the simple law of Ohm's law (I = V / R).

The temperature setting unit 254 calculates the dew point according to the humidity of the room from the temperature / humidity sensor 251a, and sets a target temperature range.
