Description

Blind type smart glass installed in the window frame of building or vehicle and control method according to its motion

The present invention relates to the field of blind type smart glass, for example, installed in a window frame of a building or a vehicle. More specifically, the present invention relates to a blind type smart glass and a method of controlling the same. It is about.

Currently, various kinds of smart glasses are being developed. Representatively, smart glass using a polymer dispersed liquid crystal (PDLC) or a suspended particle device (SPD) may be mentioned.

The smart glass using PDLC or SPD operates in a manner of scattering or absorbing light, blocking or transmitting light by a voltage applied from the outside.

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

That is, the basic structure of the smart glass is as shown in FIG. 1, liquid crystal (LC) + POLYMER or suspended particle device film (4) is arranged in the center of the drawing, each conductive film ( 3, 5) are coated.

PET films

2 and 6 and laminated

glass

1 and 7 are bonded to the outer side of the said

electroconductive films

3 and 5, respectively.

Such smart glass requires electricity for its driving. For this purpose, a method of attaching a copper mesh or a copper tape to a conductive film to make an electrode terminal and connecting the electrodes has been applied. However, when implementing the smart glass having a plurality of patterns by using the conventional technology, the application of the voltage is applied to each pattern is practically impossible because the high voltage and high current of 80V or more is required.

In addition, since the glass installed in a building or a vehicle has a large size, wiring that requires a high voltage of 80 V or more is not easy to apply, and it is also impossible to implement a fine pattern.

In addition, the wired switch or the wireless switch is used to control the smart glass, but in the case of the wireless switch, there is a risk of loss, and in the case of the wired switch, when a plurality of switches are installed, the switch must be found and operated one by one. It is inconvenient. In particular, when a plurality of smart glass is 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 Publication No. 10-2012-0092247 (published Aug. 21, 2012, the name “smart blind”) may be mentioned. In this publication, a separate switch is connected to each pattern to control each pattern independently. As described above, a cutting part is made for each pattern and a terminal is provided in the cutting part. In addition, the cumbersome task of connecting wires to individual switches is entailed. In addition, since the control of the Republic of Korea Patent Publication No. 10-2012-0092247 described above is made by a separate switch operation, operations similar to lowering or raising like a blind applied to the glass of the building are not possible.

In addition, as a method of independently controlling each pattern of smart glass, Korean Patent Publication No. 10-2005-0069535 (published on July 5, 2005, titled "Smart Window using a polymer dispersion liquid crystal and its manufacturing method) ") May be mentioned. In this patent document, a first electrode and a second electrode are alternately arranged on a transparent substrate, and a polymer dispersion liquid crystal layer is filled therebetween, and the cross-sectional shapes of the first electrode and the second electrode are manufactured in arbitrary shapes, respectively. The pattern is controlled independently. However, in such a pattern implementation method, each pattern depends only on the cross-sectional shapes of the first electrode and the second electrode, and thus the entire pattern cannot be arbitrarily controlled. In addition, there is a side that can not implement a fine pattern. In addition, in this publication, only each pattern is independently implemented within a predetermined range, and thus has nothing to do with the effect of lowering or raising the blinds applied to the glass of the building as described above.

The present invention has been made to solve the problems of the prior art, one object of the present invention is to provide a novel smart glass that can implement a fine pattern, for example 1mm to 5mm.

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

It is still another object of the present invention to provide a blind type novel smart glass which more easily connects the electrode terminal portion to the conductive film to simplify the overall manufacturing process.

It is still another object of the present invention to provide a smart glass control method for allowing a smart glass having a pattern to be implemented or not to be operated in sequence as a normal blind by motion or other means such as hand movement. .

In order to achieve the above and other objects, the present invention,

An electrochromic layer having a plurality of constant or irregular patterns and having a pattern formed by an electrical signal;

A thin film plastic film and laminated glass which are sequentially bonded to the outside of the electrochromic layer;

Conductive films are formed on both sides of the electrochromic layer, and any one of the conductive films is formed independently to form a plurality of regular or irregular patterns, and transfers control signals between the conductive films. To provide a blind type smart glass, characterized in that the bus bar (bus bar) is installed.

While resolving, the manipulation thereof is performed by the user's desired motion or motion, thereby inducing not only convenience but also interest for the user. In addition, from the user's point of view, there is an advantage that the intuitive operation by the action or the motion is made, rather than the operation of each switch can be facilitated.

Hereinafter, the present invention will be described in more detail with reference to the accompanying exemplary drawings. In the description of the present invention, descriptions of already known functions or configurations will be omitted to clarify the gist of the present invention. Also, like reference numerals denote like elements throughout the specification.

2 to 6 show the present invention. The smart glass of the present invention shown in Figures 2 to 6 is for electrically implementing any blind, it is applied to the window frame of a building or a vehicle.

First, referring to FIGS. 2 to 6 together with FIG. 1, a blind type smart glass according to one preferred embodiment of the present invention is an electrochromic layer in which a pattern is formed by an electrical signal and an outer side of the electrochromic layer. The formed thin film plastic film and laminated glass are included.

The electrochromic layer has a conductive film (3, 5) formed on both sides, the polymer dispersion liquid crystal that scatters or absorbs, blocks or transmits light by a voltage applied between the conductive films (3, 5), for example. (Polymer Dispersed Liquid Crystal, PDLC ) or Suspended Particle Device ( SPD ) is filled.

At this time, the upper conductive film 3 in the drawing is provided in a flat form without a pattern as shown in Figure 2, the lower conductive film 5 in the drawing is formed independently of each other a plurality of constant together Or irregular patterns are provided.

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 drawing, is configured to form a pattern individually and / or together per se. That is, the lower conductive film 5 which is one of the structures which comprise an electrochromic layer will have a pattern as needed.

A bus bar is provided between the upper conductive phase film 3 and the lower conductive film 5 for transmitting an electrical control signal, for example, as shown in FIG. 3. For this purpose, it is comprised so that it may be indirectly connected by a medium between a part of upper conductive film 3 and a part of lower conductive film 5.

Such bus bars may be installed in various forms. For example, the top bus bar 8 and the bottom bus bar 9 may be arranged in the same zone, or the top bus bar 8 and the bottom bus bar 9 may be arranged in another zone. Alternatively, an upper / lower board integrated bus bar may be arranged.

Hereinafter, the method of manufacturing the blind type smart glass of this invention is demonstrated.

FIG. 2 illustrates the shape of the conductive film 5 on one side and the shape of the conductive film 5, which is etched using an etching method or the like at the attachment position in order to attach the bus bar.

First, referring to FIG. 2, a conductive metal material is coated on two thin

film plastic films

2 and 6, such as PET, to form

conductive films

3 and 5 on each thin film plastic film. Thereafter, a plurality of constant or irregular patterns are formed on the conductive film of one of the two conductive films by, for example, etching.

Here, each of the patterns generated in the conductive film 5 is insulated from each other and becomes an independent conductor. One of the two conductive films made here is a conductive film whose entire surface is conductive, and one of the other conductive films is a conductive film in which a single or a plurality of regular or irregular patterns are independently conductive.

After integrating the liquid crystal (LC) + POLYMER or suspended particle device film 4 of the PDLC method or the SPD method, for example, on the pattern formed on the conductive film, a bus bar 9 such as FPCB is attached. And the bus bar 8, such as FPCB, is also attached to the other electroconductive film in which the pattern is not formed. Before attaching the

bus bars

8 and 9 to each conductive film, a material having good electrical conductivity such as silver paste may be coated or attached.

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

The bus bars can be configured simultaneously on one side of the smart glass or separately on the other side. 3 is an exemplary diagram in which the upper bus bar 8 and the lower bus bar 9 are located at a long distance. The upper bus bar 8 and the lower bus bar 9 should be insulated from each other.

The bus bar attached to the conductive film on which the pattern is formed transmits an electric signal independent of each pattern, and may be divided into several parts as necessary.

Then, two conductive films provided with the

bus bars

8 and 9 are attached to each other, and then inserted between the

laminated glass

1 and 7 as shown in FIG. 3.

Bus bars, such as FPCB, can also be insulated using the insulator 10 as needed or necessary. In addition, it is easy to install a bus bar, such as FPCB even in a regular pattern or irregular pattern can be used for various purposes.

In addition, a portion of the bus bar may be configured to be exposed to the outside of the laminated glass in order to connect the power.

The blind-type smart glass of the present invention manufactured as described above omits a method of escaping a conventional electrode terminal part by replacing an electrode terminal part for current flow applied in a driving circuit for driving the same with a bus bar such as an FPCB. It is possible to improve productivity and reduce electrode terminal connection defects.

In addition, by creating a plurality of regular patterns or irregular pattern shapes and driving them simultaneously or sequentially, they have the same effect as the blinds of general window products, and solve the problem of dust cleaning, which is a problem of the blinds of general window products. And representation of the figure.

In addition, the present invention as shown in Figures 6 to 8, includes a control unit for transmitting an electrical signal to the bus bar in response to the sensor response by the motion.

6 to 8 illustrate an operation process of the smart glass that is operated from the transparent state to the opaque state or from the transparent state to the sequentially opaque state or vice versa according to the operation of the person. In these figures, it is to be understood that the non-hatching portion represents a transparent state and the hatching portion represents an opaque state. Of course, the opposite can also be true.

As illustrated in FIGS. 6 and 7, according to a human operation, the transparent state of (a1) is changed to the opaque state of (a2) or vice versa from the opaque state of (a2) to the transparent state of (a1). You can change it. The motion and direction of the person may be different from that shown in the figure.

In addition, as illustrated in FIG. 7, a sequential opacity state of (b2), (b3), (b4), (b5), (b6), and (b7) is performed in the transparent state of (b1) according to a human operation. (B7), (b5), (b4), (b3), (b2), (b1) can be changed into a sequential transparent state.

Although not shown in the drawing, it is possible to change from the transparent state to the opaque state collectively, or vice versa from the opaque state to the collective state according to the motion of the person.

8 illustrates various positions at which the sensor is mounted. 8 shows the sensor position when in a single smart window. The type and location of the sensor can be changed to suit the installation environment. Here, the motion and direction of the person may be different from that shown.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.
