Description

TECHNICAL FIELD [0001] The present invention relates to a blind type smart glass installed in a window frame of a building or a vehicle, and a control method according to the motion of the blind type smart window,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smart glass field of a blind type, for example, installed in a building or a window frame of a vehicle, and more particularly, to a blind type smart glass having a simple manufacturing process, .

Several types of smart glasses are currently being developed. Typically, smart glass using Polymer Dispersed Liquid Crystal (PDLC) or Suspended Particle Device (SPD) can be mentioned.

Such a smart glass using PDLC or SPD operates in a manner of scattering, absorbing, intercepting or transmitting light by an externally applied voltage.

When PDLC or SPD is used in smart glass, a thin film of plastic film such as PET is usually coated on the conductive film and then inserted into the window frame while being inserted between the two laminated glasses.

That is, the basic structure of the smart glass is such that a liquid crystal (LC) + POLYMER or a suspended particle device film 4 is disposed in the middle of the drawing, as exemplarily shown in Fig. 1, 3, 5) are coated. PET films 2 and 6 and bonding glasses 1 and 7 are bonded to the outside of the conductive films 3 and 5.

Such a smart glass requires electricity for its operation. For this purpose, a copper mesh or copper tape is usually attached to a conductive film to form an electrode terminal and a method of connecting electrodes is applied. However, when a smart glass having a plurality of patterns is to be realized by utilizing the conventional technique, since the voltage applied to each pattern is practically required to be higher than 80 V and a high current, its application is practically impossible.

In addition, the glass installed in a building or a vehicle has a complicated wiring requiring a high voltage of 80 V or more because of its size, so that it is not easy to apply and it is also impossible to realize a fine pattern.

Conventionally, a wired switch or a wireless switch is used to control the smart glass, but there is a risk of loss of the wireless switch. In the case of a wired switch, when a plurality of switches are installed, There is an inconvenience. Especially, when a plurality of smart glasses are installed in one place, it is impossible to use a wired / wireless switch to drive only the desired smart glass.

As a representative example, Korean Patent Laid-Open No. 10-2012-0092247 (published on Aug. 21, 2012, entitled "Smart Blind") may be mentioned. In this patent document, a separate switch is connected to each pattern in order to independently control each pattern, so that a cutting portion is formed for each pattern and a terminal is installed in the cutting portion as described above And the cumbersome work of connecting the wires to individual switches. In addition, since the above-mentioned Korean Patent Laid-Open Publication No. 10-2012-0092247 is controlled by a separate switch operation, it is impossible to perform a similar operation as a blind applied to a glass of a building.

As one of the methods for independently controlling each pattern of smart glass, Korean Patent Publication No. 10-2005-0069535 (published on July 5, 2005, entitled "Smart Window Using Polymer Dispersed Liquid Crystal and Its Manufacturing Method Quot; can be mentioned. In this publication, the cross-sectional shapes of the first electrode and the second electrode are formed in an arbitrary shape while the first electrode and the second electrode are alternately arranged on the transparent substrate and the polymer dispersed liquid crystal layer is filled therebetween, And the pattern is controlled independently. However, in this pattern implementation method, each pattern depends on the cross-sectional shape of the predetermined first electrode and the second electrode, but the entire pattern can not be controlled arbitrarily. In addition, it is impossible to realize a fine pattern. In addition, in this patent document, since each pattern is independently implemented within a set range, it is completely independent of the effect of raising or lowering the blind as applied to the glass of the building as described above.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art, and one object of the present invention is to provide a novel smart glass which can realize a fine pattern of, for example, 1 mm to 5 mm.

Another object of the present invention is to provide a novel smart glass of a blind type which can give a blind effect without making any pattern in advance at a portion which is substantially discolored by an electrical signal, for example, a portion using PDLC or SPD .

It is still another object of the present invention to provide a novel smart glass of the blind type which makes it possible to more easily connect the electrode terminal portion to the conductive film, thereby simplifying the entire manufacturing process.

It is yet another object of the present invention to provide a smart glass control method that allows a smart glass in which a pattern is not implemented or implemented to be operated in sequence, such as a normal blind, by motion or other means such as hand movement .

In order to achieve the above and other objects,

In the present invention, the sensor may be an ultrasonic wave, a laser, an infrared ray, or a sensor for sensing sound.

According to the blind-type smart glass of the present invention, the escape process by cutting for each pattern of the electrochromic layer having a plurality of uniform or irregular patterns and forming a pattern by an electrical signal, , It is possible to prevent defective terminal and deformation of conductive film due to the connection of a plurality of terminals and power lines, and to prevent electric shock accidents and disconnection failures which may occur in smart glass by eliminating power lines directly connected to a plurality of terminal portions And the operation thereof is performed by the desired operation or motion of the user, thereby providing the user with convenience as well as interest. In addition, there is an advantage that the user can intuitively perform operations by acting or motion rather than manipulating the respective switches, thereby making it convenient.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the following illustrative drawings. In describing the present invention, a description of known functions or configurations will be omitted for the sake of clarity of the present invention. In addition, like reference numerals designate like elements throughout the specification.

2 to 10 show the present invention. The smart glass of the present invention shown in Figs. 2 to 10 is for electrically implementing any blind, and is applied to a window frame of a building or a vehicle.

2 and 10, a blind type smart glass according to one preferred embodiment of the present invention includes an electrochromic layer in which a pattern is formed by an electrical signal, And includes a formed thin film plastic film and a laminated glass.

The electrochromic layer has electroconductive films 3 and 5 formed on both sides thereof. The electrochromic layer 3 and the electroconductive films 3 and 5 are formed of a polymer dispersed liquid crystal material which scatters, absorbs, blocks, or transmits light by, (Polymer Dispersed Liquid Crystal, PDLC ) or Suspended Particle Device ( SPD ).

At this time, the upper conductive film 3 is provided in the form of a flat plate without a pattern as shown in FIG. 2, and the lower conductive films 5 are formed independently of each other, Or an irregular pattern is formed.

These conductive films 3 and 5 serve as electrodes, and any one of the conductive films, for example, the lower conductive film 5 in the figure itself is configured to form a pattern individually and / or together. That is, the underlying conductive film 5, which is one of the electrochromic layers, has a necessary pattern.

A bus bar for transmitting an electrical control signal is provided between the upper conductive film 3 and the lower conductive film 5, for example, as shown in FIG. To this end, a part of the upper conductive film 3 and a part of the lower conductive film 5 are indirectly connected by a medium.

These busbars may be installed in various forms. For example, the upper plate bus bar 8 and the lower plate bus bar 9 are disposed in the same space as shown in FIG. 3 (a) The lower plate bus bar 9 may be disposed. Alternatively, as shown in FIG. 3 (f), the bus bar 10 integrated with the upper and lower plates may be disposed. Figs. 3 (a) to 3 (i) show various aspects in which bus bars are arranged.

Hereinafter, a method of manufacturing a blind type smart glass of the present invention will be described.

In Fig. 2, a pattern is formed on the conductive film 5 on one side, and a shape escaped by etching or the like at the attachment position is shown for attaching the bus bar.

First, referring to FIG. 2, a conductive film is coated on each of two thin film plastic films 2 and 6 such as PET, and conductive films 3 and 5 are formed on the respective thin film plastic films to form a conductive film Thereafter, a plurality of uniform or irregular patterns are formed in the conductive film of one of the two conductive films by, for example, etching.

Here, each pattern produced in the conductive film 5 becomes an independent conductor by insulating the pattern boundary. One of the two conductive films formed here is a conductive film on which the entire surface is electrically conductive, and one conductive film is a conductive film in which a single or a plurality of uniform or irregular patterns are electrically insulated.

A liquid crystal (LC) + POLYMER or a suspended particle device film 4 of PDLC or SPD method is integrated on a pattern formed on the conductive film, and then a bus bar 9 such as FPCB is attached. Then, a bus bar 8 such as FPCB is attached to another conductive film on which no pattern is formed. Before the bus bars 8 and 9 are attached to each of the conductive films, a material having a good electrical conductivity such as a silver paste may be coated or adhered.

3 shows a state in which a bus bar such as FPCB is attached to the conductive film.

The bus bars can be configured simultaneously on one side of the smart glass or on the other (Figs. 3, 4, 5, 6, and 7). 3 (a), 3 (d) and 3 (g) are views showing the upper plate bus bar 8 and the lower plate bus bar 9 located close to each other, The bus bar 8 and the lower plate bus bar 9 are located remotely. 3 (c), 3 (f), and 3 (i) show examples of the integrated bus bar in which the upper plate bus bar and the lower plate bus bar are integrally formed. Here, the upper plate bus bar 8 and the lower plate bus bar 9 should be insulated from each other.

The bus bars attached to the conductive films on which the patterns are formed transmit electrical signals independent of each pattern, and can be connected to each other as needed (see FIG. 10).

Thereafter, two conductive films provided with the bus bars 8 and 9 are brought into contact with each other and then bonded to the bonded glass 1 and 2 as shown in Figs. 3 (g), 3 (h) and 3 7).

The bus bar such as the FPCB may be insulated by using the heat insulating member 11 according to the type and necessity. In addition, it is easy to install a bus bar such as FPCB in a certain pattern or an irregular pattern and can be used for various purposes (see Figs. 8 and 9).

In addition, a part of the bus bar can be configured to be exposed to the outside of the joint glass to connect the power source.

In the blind-type smart glass of the present invention manufactured in this way, a method of avoiding the conventional method for avoiding the electrode terminal portion by replacing the electrode terminal portion for current flow applied in the driving circuit for driving the same with a bus such as FPCB is omitted The productivity can be improved and the defective connection of the electrode terminal portion can be reduced.

In addition, by creating a plurality of uniform patterns or irregular pattern shapes and simultaneously or sequentially driving the patterns, the same effect as the blinds of general window products can be obtained, thereby solving the problem of dust cleaning, which was a problem of blinds of general window products, And the image representation.

Also, as shown in FIGS. 11 to 18, the present invention includes a controller for transmitting an electrical signal to a bus bar in response to a sensor response by motion.

Here, the operation and direction of a person may be different from that shown in the figure.

As illustrated in FIG. 13, the transparent state of (c1) changes from the transparent state of (c1) to the opaque state of (c2), or vice versa (c2) . At this time, the operation and direction of the person may be different from that shown in the figure.

As illustrated in Fig. 14, the transparent state of (d1) changes from (d2), (d3), (d4) and (d5) to a sequential opaque state or vice versa (d5) (d4), (d3), (d2), and (d1). At this time, the operation and direction of the person may be different from that shown in the figure.

As illustrated in Fig. 15, the transparent state of (e1) is changed from the transparent state of (e1) collectively to the opaque state of (e2) or vice versa (e2) . At this time, the operation and direction of the person may be different from that shown in the figure.
