Abstract

Disclosed are 3-dimensional (3D) glasses using an electrically reacting polarizing film. The polarizing film according to the present invention is coated on each lens of a pair of glasses and has an initial light transmittance. Also, when a voltage from a power supply is applied to the polarizing film, the polarized arrangement of the polarizing film may be varied to reduce light transmittance and realize a 3D image. Thus, the electrically reacting polarizing film may be attached to a normal pair of glasses so that the normal glasses can be used as 3D glasses. In some cases, the normal glasses on which the electrically reacting polarizing film is attached may be used as sunglasses. Also, since the voltage from the power source is applied through a detachable power switch which is easily portable, a user does not need to separately carry a normal pair of glasses, a pair of sunglasses, and a pair of 3D glasses. Also, when the wearer of glasses views a 3D image, since it is unnecessary to wear two pairs of glasses, the user may view the 3D image in comfort.

Description

3D glasses using an electrically reactive polarizing film

The present invention relates to three-dimensional glasses, and more particularly to three-dimensional glasses using an electro-responsive polarizing film.

3D stereoscopic image technology has various applications such as information communication, broadcasting, medical, education and training, military, game, animation, virtual reality, CAD, industrial technology, etc. It is a core foundation technology of information and communication.

In general, the three-dimensional sense perceived by a person is caused by the degree of change in the thickness of the lens depending on the position of the object to be observed, the difference in angle between the two eyes and the object, the difference in the position and shape of the visible object in the left and right eyes, and the movement of the object. Lag and other effects such as various psychological and memory effects are produced in combination.

Among them, binocular disparity, which appears as the human eyes are positioned about 6 to 7 cm apart in the horizontal direction, can be said to be the most important factor of the three-dimensional effect. In other words, the binocular parallax makes us look at the angle with respect to the object, and because of this difference, the images coming into each eye have different images, and when these two images are transmitted to the brain through the retina, the brain receives these two pieces of information. You can feel the original three-dimensional stereoscopic image by fusion with each other exactly.

The stereoscopic image display apparatus is classified into a spectacle type using specially manufactured three-dimensional glasses and a non-glass type without using three-dimensional glasses.

Conventional 3D glasses are used as exclusive glasses for viewing 3D stereoscopic images regardless of the method used. In other words, the 3D glasses are unnecessary except for watching a 3D stereoscopic image.

And software.

1 shows an electroreactive polarizing film according to an example of the present invention, and FIG. 2 shows an example of the electroreactive polarizing film structure of FIG. 1.

The electrically reactive polarizer films PF1 and PF2 shown in FIG. 1 may be coated on lenses of three-dimensional glasses, and function as general polarizing films having initial transparency when a power supply voltage is not applied. However, when a power supply voltage is applied, it is a film in which polarization characteristics change. The polarization direction of the electrically reactive polarizing films PF1 and PF2 is changed when a power supply voltage is applied. That is, similar to the driving principle of the LCD, an electric field is generated between both sides of the film, and the alignment direction of the polarization rotates in response to the generated electric field.

In general LCD panels, a liquid crystal layer is disposed between two polarizing plates having perpendicular polarization directions, and is driven in such a manner that light transmittance is controlled by adjusting an arrangement direction of liquid crystals by applying an electric field to the liquid crystal layer. do. However, in the LCD panel, light is not transmitted by two polarizing plates having an orthogonal polarization direction unless an electric field is applied. In contrast, the electroreactive polarizing films PF1 and PF2 of the present invention shown in FIG. 2 include one polarizing plate and a liquid crystal layer. As in the LCD panel, an electric field is applied to the liquid crystal layer to adjust the alignment direction of the liquid crystals, thereby controlling light transmittance and polarization direction.

Unlike the LCD panel, the electro-responsive polarizing films PF1 and PF2 have only one polarizing plate, and thus have an initial light transmittance, that is, an initial transparency even when no electric field is applied to the liquid crystal layer. When a power supply voltage is applied, an electric field is applied to the liquid crystal layer as described above to adjust the arrangement direction of the liquid crystal, thereby adjusting the arrangement direction to a direction for viewing a 3D image of a polarization filter method. Although not shown, the electro-responsive polarizing films PF1 and PF2 are provided with ITO electrodes (Indium Tin Oxide electrodes) on both sides to generate an electric field by receiving a power supply voltage. ITO electrodes are materials commonly used as electrodes of display devices as transparent electrodes. FIG. 2 is an example of the electro-responsive polarizing films PF1 and PF2, and another polarizing film having an initial transparency and having a polarization direction adjustable as a power supply voltage is applied may be used.

The conventional three-dimensional glasses of the polarization filter type was set so that only the polarization of the specified direction is transmitted. However, in the present invention, the polarization direction of the electrically reactive polarizing films PF1 and PF2 may be adjusted according to the voltage level of the power voltage applied thereto. Accordingly, when the power supply voltage is not applied, the polarization characteristic is changed to have an initial polarization direction, but when the power supply voltage is applied, the polarization characteristic is changed to have a polarization direction corresponding to the voltage level of the applied power supply voltage.

And the initial transparency of the electro-responsive polarizing film (PF1, PF2) can be adjusted by the film manufacturer. The polarizing film basically does not have transparency or light transmittance like glass because it only passes light having a wavelength traveling in a certain direction. Recently, however, with the development of technology, polarizing films having high transmittance have been manufactured. Thus, a polarizing film having a level of transparency similar to that of ordinary transparent glass can be supplied.

Meanwhile, the power connection part CN is connected to one end of the electro-responsive polarizing films PF1 and PF2. The power connection CN has electrically conductive lines CL1 and CL2 that are applied or attached onto the insulator ISO. The electrically conductive lines CL1 and CL2 of the power connection unit CN are electrically connected to the separate power control switch for supplying the power voltage, so that the power voltage supplied from the separate power control switch is the electrically reactive polarizing films PF1 and PF2. To be applied to the ITO electrode disposed on both sides of the. In order to apply an electric field to the liquid crystal layers of the electro-responsive polarizing films PF1 and PF2, the first electrically conductive line CL1 of the power supply connection CN has a positive power supply on one surface of the electro-responsive polarizing films PF1 and PF2. The voltage may be applied, and the second electrically conductive line CL2 may apply a negative power supply voltage to the other surfaces of the electrically reactive polarizing films PF1 and PF2. That is, the power connection part CN receives two power supply lines CL1 and CL2 for applying the positive power supply voltage and the negative power supply voltage from the separate power supply control switch to the electroreactive polarizing films PF1 and PF2, respectively. Each is provided.

On the other hand, the power connection part CN is connected to the direction in which the bridges of the glasses are arranged in the electro-responsive polarizing films PF1 and PF2 when the electro-responsive polarizing films PF1 and PF2 are coated on the lenses of the glasses.

Referring to FIG. 3, the three-dimensional glasses have two lenses, and a bridge 11 is disposed between the two lenses L1 and L2. Then, the electroreactive polarizing films PF1 and PF2 of FIG. 1 are coated on the coated two lenses L1 and L2. When the electro-responsive polarizing films PF1 and PF2 are coated on the lenses L1 and L2, the power connection part CN of the electro-responsive polarizing film is coated so as to be in the direction of the bridge 11 of the glasses. The bridge 11 is connected to the nose support 13 of the glasses. And the opposite side of the bridge 11 in the two lenses (L1, L2) is coupled to one end of the spectacles leg hinge 15 for the spectacles legs 17 are connected. The other end of the eyeglass leg hinge 15 is coupled to the eyeglass leg 17.

In the present invention, the bridge 11 is coupled with the power connection CN of FIG. The power connection CN is coupled in a form surrounding the bridge 11 (ie, coating the bridge). In this case, the two electrically conductive lines CL1 and CL2 for receiving the positive power supply voltage and the negative power supply voltage, respectively, may be disposed on the front and rear surfaces of the bridge 11. The two electrically conductive lines CL1 and CL2 of the power connection CN are joined to face the outside of the bridge 11. The two electrically conductive lines may be disposed on both the front surface of the bridge 11 or both of the rear surfaces thereof. However, when the two electrically conductive lines CL1 and CL2 are disposed adjacent to each other, an electrical short may occur. Therefore, the two electrically conductive lines CL1 and CL2 are preferably disposed separately on the front and rear surfaces of the bridge 11 so as not to short-circuit each other.

3 is a view showing one type of general glasses generally referred to as rimless glasses. That is, the outer shape of the three-dimensional glasses 10 of FIG. 2 is the same as the general glasses. However, unlike the general glasses, the three-dimensional glasses 10 of FIG. 2 are coated with the lenses L1 and L2 of the electrically reactive polarizing films PF1 and PF2 of FIG. 1. The electroreactive polarizing films PF1 and PF2 are films in which the polarization direction is changed when a power supply voltage is applied as described above. In addition, a power supply voltage may be applied through two conductive lines CL1 and CL2 of the power connection part CN connected to the electrically reactive polarizing films PF1 and PF2.

In FIG. 3, the power connection part CN has a structure coupled to the bridge 11 of the 3D glasses 10. The power connection CN may be coupled in a structure surrounding the bridge 11. As described above, the two power connection portions CN connected to the electro-responsive polarizing films PF1 and PF2 each have two conductive lines CL1 and CL2, and the two conductive lines CL1 and CL2 are bridged. It is coupled to the front and back of each. That is, two power connection parts CN connected to the electro-responsive polarizing films PF1 and PF2 may be implemented to surround both ends of the bridge 11. When the power source connection CN has a structure separated from the bridge 11, the power source connection CN appears on the appearance of the three-dimensional glasses 10, which results in a deterioration of the appearance of the three-dimensional glasses. do. Therefore, in the present invention, a structure in which the power connection CN is coupled to the bridge 11 is illustrated. In addition, since the power connection CN is simply coated on the bridge, it may be provided in the form of a film. If the power connection CN is not coated on the bridge, other supporting means will be required for coupling with the separate power control switch PWS. However, in the case of the glasses having the spectacle frame instead of the frameless glasses illustrated in FIG. 2, the power supply connection CN may be coupled between the two lenses L1 and L2 of the spectacle frame rather than the bridge 11. However, since the power supply connection CN serves to transfer the applied power voltage to the electro-responsive polarizing films PF1 and PF2, the bridge 11 is connected to the bridge 11 in a structure in which the power supply connection CN is coupled with the bridge 11. If implemented with an electrically conductive material, an electrical short may occur. Although the power connection CN has an insulator ISO to insulate the two conductive lines CL1, CL2 and the bridge, the power connection CN may wear out due to contact with the separate power control switch PWS. . Therefore, in order to prevent the occurrence of an electrical short, the bridge 11 is preferably implemented with an electrical insulator. In addition, in the structure in which the power supply connection CN is coupled to the spectacle frame, the spectacle frame is preferably implemented as an electrical insulator. However, users with various tastes may prefer eyeglass frames or bridges made of an electrically conductive material. In this case, a transparent insulating material may be further coated on the outside of the spectacle frame or the bridge 11 in order to add electrical insulation to the spectacle frame or the bridge 11.

The separate power control switch PWS is a power supply device that applies a power supply voltage to the electrically reactive polarizing films PF1 and PF2. That is, the separate power control switch PWS may be implemented as a battery for supplying a power voltage to be applied to the electrically reactive polarizing films PF1 and PF2. The separate power control switch PWS is coupled to the outside of the bridge 11 surrounded by the power connection CN to supply a positive power voltage to the first conductive line CL1, and to the second conductive line CL2. Apply a negative supply voltage. As a result, an electric field is formed in the electro-responsive polarizing films PF1 and PF2 to change the polarization direction. As described above, the three-dimensional glasses according to the present invention have a three-dimensional image when the power supply voltage is supplied to the electro-responsive polarizing films PF1 and PF2 so that the polarization characteristics of the electro-responsive polarizing films PF1 and PF2 change. Since it can be viewed, the detachable power control switch (PWS) is not simply a power supply, but simultaneously performs a function as a switch for changing the use of the three-dimensional glasses.

That is, the 3D glasses according to the present invention are normally used as general glasses by removing the detachable power control switch (PWS), and when the user wants to view a 3D stereoscopic image, simply bridge the detachable power control switch (PWS). By binding to (11) the polarization direction of the electro-responsive polarizing film (PF1, PF2) is changed to allow to enjoy a three-dimensional image.

4 shows a detailed structure of the separate type power control switch of FIG.

As shown in FIG. 4, the detachable power control switch PWS has a U-shaped clip-like structure to be coupled to the bridge 11 of the three-dimensional glasses 10. The separate power control switch PWS is a battery, and is a polarity terminal for applying power voltages having different polarities to the first and second conductive lines CL1 and CL2 of the power connection part CN coated on the bridge 11. Is provided inside the clip shape. In FIG. 4, assuming that the first and second conductive lines CL1 and CL2 are disposed on the front and rear surfaces of the bridge 11, the polarity terminals of the separate power control switch PWS face each other inside the clip shape. However, if both of the first and second conductive lines CL1 and CL2 are disposed at the front of the bridge 11 or at the rear of the bridge 11, the first and second conductive lines CL1 and CL2 may be disposed on one surface inside the polarity terminal of the detachable power control switch PWS. They will be placed next to each other. The separate power control switch PWS may be implemented as a disposable battery, and in some cases, may be implemented as a rechargeable battery. In FIG. 4, the detachable power control switch PWS is coupled to the bridge 11 in a clip shape. However, when the detachable power control switch PWS is coupled only to the bridge 11, there is a fear that the fixing property is weak. In other words, the fixed power control switch PWS is not stable and may swing back and forth. If the fixing of the separate power control switch PWS is not stable, the connection between the polarity terminal of the separate power control switch PWS and the first and second conductive lines CL1 and CL2 of the power connection part CN becomes unstable and short-circuited. Or problems such as disconnection may occur. Accordingly, the detachable power control switch PWS may be designed to be coupled not only to the bridge 11 but also to lenses L1 and L2 or glasses frames on both sides according to the design of the glasses. When the detachable power control switch PWS is coupled not only to the bridge 11 but also to the lenses L1 and L2 or the glasses frames on both sides, the detachable power control switch PWS is stably fixed to prevent problems such as short circuit and disconnection. Can be.

In FIG. 3, the electro-responsive polarizing films PF1 and PF2 are coated only on the front surfaces of the lenses L1 and L2. However, as illustrated in FIG. 5, the electrically reactive polarizing films PF1 and PF2 may be coated on the rear surfaces of the lenses L1 and L2. In addition, as illustrated in FIG. 6, the electrically reactive polarizing films PF1 and PF2 may be coated on both surfaces of the lenses L1 and L2. When the electro-responsive polarizing films PF1 and PF2 are coated on both surfaces of the lenses L1 and L2, the electro-responsive polarizing films PF1 and PF2 coated on the front side and the electro-responsive polarizing films PF1 coated on the rear surface , PF2) can be controlled individually.

And when the electro-responsive polarizing film (PF1, PF2) is coated on both surfaces of the lens (L1, L2), the electro-responsive polarizing film (PF1, PF2) is coated on the front and the electro-responsive polarizing film (coated on the back) PF1 and PF2) may not be the same polarizing film. For example, the front surface of the lens (L1, L2) is coated with an electro-responsive polarizing film (PF1, PF2) with a liquid crystal layer, as shown in Figure 2, while the rear of the lens is a general polarizing film without a liquid crystal layer This may be used. In addition, the polarization directions of the polarizing film of the polarizing film coated on both sides may be different from each other.

In addition, Korean Laid-Open Patent Publication No. 2001-0072703 (hereinafter referred to as Invention 1) discloses an electrically switchable composite film having a conical cavity using electrophoretic moving particles in a rheologically controllable suspension. Doing. Cited Invention 1 discloses an electric switching composite film whose transparency is adjusted according to an electric field. Accordingly, the three-dimensional glasses of the present invention may be used together with the electrically reactive polarizing films PF1 and PF2 together with the electrically switchable composite film of the invention. For example, the electro-responsive polarizing films PF1 and PF2 may be coated on the front surfaces of the lenses L1 and L2, and the electrically switchable composite film of the present invention 1 may be coated on the rear surfaces of the lenses L1 and L2. On the contrary, the electrically reactive polarizing films PF1 and PF2 may be coated on the rear surfaces of the lenses L1 and L2, and the electrically switchable composite film of the present invention 1 may be coated on the front surfaces of the lenses L1 and L2.

In addition, the electro-responsive polarizing films PF1 and PF2 and the electrically switchable composite film may be separately controlled by having a power supply connection CN separately.

As shown in FIG. 6, when the electro-responsive polarizing films PF1 and PF2 are coated on both surfaces of the lenses L1 and L2, or the electro-responsive polarizing films PF1 and PF2 and the electrically switchable composite film are coated. There may be provided with a plurality of polar terminals to individually control the film coated on both surfaces of the lens (L1, L2). The films coated on both surfaces of the lenses L1 and L2 are not necessarily controlled equally. Rather, if different electric fields can be applied to the films coated on both surfaces of the lens (L1, L2), it is possible to provide a more diverse three-dimensional glasses using environment. For example, by adjusting the voltage level of the power supply voltage applied to the electro-responsive polarizing films PF1 and PF2 coated on both surfaces of the lenses L1 and L2 differently, it is not only normal glasses and 3D glasses but also sunglasses. You can make it available. When using the three-dimensional glasses according to the invention as a sunglass can be used similarly to polarized sunglass currently on the market. Since polarized sunglass also uses a method of filtering light by polarization, in principle, polarized sunglass and three-dimensional glasses have the same structure. Therefore, the three-dimensional glasses according to the present invention can be used not only as a three-dimensional glasses for appreciating the three-dimensional image in the normal glasses, but also can be used by changing the ordinary glasses to sunglasses. In addition, as in the case of being used as a three-dimensional glasses, it is possible to change the use by using only a simple operation of combining the detachable power control switch (PWS), and do not have to carry a plurality of glasses for each use, very easy to use. In addition, when the electro-responsive polarizing films PF1 and PF2 and the electrically switchable composite film are coated on both surfaces of the lenses L1 and L2, respectively, only the electro-responsive polarizing films PF1 and PF2 are used as three-dimensional glasses. And only the electrically switchable composite film can be controlled and used as sunglass.

When the film is coated on both surfaces of the lenses L1 and L2, the film on both sides has a separate power supply connection CN in order to individually control the films on both sides, and the individual power connection connections CN each have a bridge 11. It can be placed on the front and back. For example, the first and second conductive lines CL1 and CL2 of the power connection portion CN of the film coated on the front surface are all disposed on the front surface of the bridge 11, and the power connection portion CN of the film coated on the back surface. Both first and second conductive lines CL1 and CL2 may be disposed on the rear surface of the bridge 11. As illustrated in FIG. 7, two polarity terminals are disposed on both inner surfaces of the detachable power control switch PWS, so that the first and second conductive lines CL1 and CL2 are disposed on the front surface of the bridge 11. And the first and second conductive lines CL1 and CL2 disposed on the rear surface of the bridge 11. In addition, the detachable power control switch PWS further includes a switch element including a silicon controlled rectifier (SCR), so that the film and the lenses L1 and L2 coated on the front surface of the lenses L1 and L2 are provided. Different voltages may be applied to the film coated on the rear surface. Similarly, even when the electro-responsive polarizing films PF1 and PF2 are coated on only one surface of the lenses L1 and L2, the voltage level applied to the electro-responsive polarizing films PF1 and PF2 may be adjusted using a switch element. .

As shown in FIG. 8, the three-dimensional glasses 10 of the present invention have a structure in which the detachable power control switch PWS is coupled to the bridge 11. It doesn't change much in appearance. That is, it is possible to maintain the shape of the existing glasses as it is.

In the case of the existing three-dimensional dedicated glasses are not provided to the individual user, it is not considered for each user's visual difference or facial contour. Therefore, the fit was not good. In addition, a user who originally wore glasses had to wear two glasses to watch a 3D stereoscopic image. In other words, it did not provide a comfortable environment for viewing 3D stereoscopic images. However, since the three-dimensional glasses according to the present invention can be provided by coating the electro-responsive polarizing films (PF1, PF2) to the lens of the general glasses, the electro-responsive polarizing films (PF1, PF2) is coated on the previously worn glasses You can convert it to 3D glasses and use it.

In addition, it can be selectively used as general glasses or three-dimensional glasses and sunglasses depending on the presence or absence of a separate power control switch (PWS). In addition, when the detachable power control switch PWS includes a switch, the application may be switched to general glasses or 3D glasses and sunglasses according to the switch operation.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
