As the demand for personal privacy protection increases, various products are being developed for privacy protection of electronic products.

Electronics that need to ensure personal privacy include cell phones, laptops, and tablet PCs. These products can be easily used in a public place, and the contents displayed on the screen may include private contents.

Therefore, a monitor control panel is mounted on the monitors of such electronic products. In other words, the control panel is attached to a monitor (output window) of a mobile phone, a notebook computer, a tablet PC, etc., and shields the privacy of the user by blocking the lateral transmission of light and narrowing the viewing angle.

On the other hand, the recently developed wide-area control panel can selectively control the viewing angle depending on whether an electrical signal is applied or not. Therefore, the user can freely select the viewing angle by changing the electrical signal applied to the coarse adjustment control panel according to whether or not the privacy protection is required.

In the liquid crystal display device to which the conventional coarse control panel configured as described above is applied, when the electric field applied to the coarse adjustment control panel 20 is cut off, the user can view the image in the wide viewing angle mode. On the contrary, , The user can view the image in the narrow field mode.

On the other hand, the conventional optical coherence control panel 20 uses a lower glass substrate 22 and an upper glass substrate 21, and a liquid crystal layer is formed therebetween. Further, spacers are scattered in the liquid crystal layer in order to keep the distance between the two glass substrates 21, 22.

In order to manufacture the conventional optical coherence control panel 20, two green glass substrates are cleaned, a liquid crystal is applied to a glass substrate, a seal is printed on one of the two glass substrates, And finally, a process of cutting the ledge glass substrate according to the size of the coarse control panel must be performed.

As described above, since the conventional optical coherence control panel 20 uses two green glass substrates, the manufacturing cost is high.

Further, in the conventional climate control panel 20, the upper glass substrate and the lower glass substrate are manufactured using the two raw glass substrates, and then the two glass substrates are bonded together through the seal, Therefore, the manufacturing process is complicated and the manufacturing cost is also increased.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a view illustrating a manufacturing method of a climate control panel according to the present invention, and FIG. 3 is a flowchart illustrating a manufacturing method of a climate control panel according to the present invention.

Referring to FIG. 2 (a), the surface of the raw film 211, 221 to be used as the upper film or the lower film is cleaned (S102). The raw-material films 211 and 221, which have been transferred to the cleaning device while being wound on the rollers, are released from the rollers and can be cleaned.

Next, referring to FIG. 2B, the alignment film materials 212 and 222 for forming an alignment film are printed on the opposite sides of the cleaning films 211 and 221, respectively (S104). The alignment film materials 212 and 222 printed on the surfaces of the raw film films 211 and 221 are formed as alignment films 213 and 223 on the surface of the raw film through a rubbing process after being baked. The alignment films 213 and 223 function to align the liquid crystal in a predetermined direction.

On the other hand, prior to the formation of the alignment film, a transparent electrode (ITO) is deposited on the surfaces of the raw film films 211 and 221. The transparent electrode ITO functions to apply a voltage to the upper film and the lower film. The voltage applied to the transparent electrode changes the state of the liquid crystal mixture formed between the upper film and the lower film, Mode or a narrow field mode can be implemented.

2 (c), a seal 214 or a spacer 224 is formed on the alignment films 213 and 223 (S106). The seal 214 or the spacer 224 may be formed on either one of the raw film 211 or 221, but may be formed on each of the two raw films. 2C, a process of forming the seal 214 on the upper raw film 211 to be used as an upper film and a process of forming a spacer 224 on the lower raw film 221 to be used as the lower film Are formed.

However, the process (S106) of forming the seal 214 or the spacer 224 may be omitted. That is, since the seal is formed for the purpose of attaching the two raw film films 211 and 221, and the spacer is formed for the purpose of keeping the interval of the two raw film films constant, The process of forming the seal or the spacer may be omitted.

For example, the liquid crystal mixture to be described below is a material in which an ultraviolet curing resin is mixed with a liquid crystal which is generally applied to a liquid crystal display. When such a liquid crystal mixture is cured with ultraviolet rays, the ultraviolet curing resin is hardened, It is possible to maintain a constant interval between them. Further, the orientation film or the raw film may be stuck to each other while the ultraviolet curable resin is cured. Therefore, when a liquid crystal mixture that performs the above-described functions is applied, the step of forming a seal or a spacer (S106) may be omitted.

2 (d), a first liquid crystal mixture 230a is applied to a first lower film 220a having an orientation film 223 formed on a lower raw sheet film 211, and a first liquid crystal mixture 230a The first lower film 220a coated with the adhesive layer 220a is adhered to the first upper film 210a having the orientation film 213 formed on the upper raw film 211 by the adhesion roller 300 in step S108. Such a process is called a lamination process.

That is, in the present invention, the first upper film 210a and the first lower film 220a, which are separately formed, are bonded together via the liquid crystal mixture 230a.

As described above, the first liquid crystal mixture 230a used in the above process is formed by mixing ultraviolet curable resin and liquid crystal generally used in a liquid crystal display device. In addition, the first liquid crystal mixture 230a contains a photo-initiator.

Liquid crystal is a material that can control birefringence and is also applied to panels of liquid crystal display devices.

The ultraviolet ray hardening resin is a resin that is cured by ultraviolet rays, for example, can be a UV epoxy, and various kinds of monomers (monomers) which are cured by ultraviolet rays can be applied. That is, various kinds of monomers that can be cured to ultraviolet light and can be mixed with liquid crystal can be applied to the present invention.

The photoinitiator refers to a material which, when mixed with an ultraviolet curable resin, absorbs energy from an ultraviolet lamp to initiate a polymerization reaction. That is, when exposed to ultraviolet rays, the photoinitiator emits energy necessary for initiating photopolymerization of the monomer, which is an ultraviolet curable resin, so that the monomer is changed into a polymer (polymer) state. That is, the photoinitiator performs a function of initiating a process (a photopolymerization process) in which a monomer (monomer) as an ultraviolet curable resin is cured with a polymer (polymer).

Next, referring to FIG. 2E, the first upper film 210a and the first lower film 220a are bonded together through the first liquid crystal mixture 230a through the laminating step (S108) And the first control panel 200a are formed.

The first liquid crystal mixture 230a in the state of the first climate control panel 200a is a liquid material in which the above three materials, liquid crystal, ultraviolet curable resin and photoinitiator are mixed. Since the first liquid crystal mixture 230a in such a state is mixed with the liquid crystal, the ultraviolet curable resin and the photoinitiator, the viscosity is lower than that of a general liquid crystal. Accordingly, even when the laminating step (S108) is performed, the first liquid crystal mixture 230a can be bonded to the first upper film 210a in a state in which the first liquid crystal mixture 230a is applied between the first lower films 220a.

That is, since the viscosity of the first liquid crystal mixture 230a is low, the liquidity is low. Accordingly, the first liquid crystal mixture 230a does not escape from between the first upper substrate 210a and the first lower substrate 220a even when the first upper substrate 210a and the first lower substrate 220a are bonded together .

2 (f), a first liquid crystal mixture 230a is formed on the upper side of the first condensation control panel 200a formed between the first upper substrate 210a and the first lower substrate 220a, Ultraviolet rays are irradiated to the first control panel 200a using an ultraviolet lamp to cure a part of the first liquid crystal mixture at step S110.

In the mask 260, a plurality of open holes are formed in the form of a matrix to form barrier ribs in the liquid crystal mixture. When the ultraviolet ray passing through the open hole of the mask 260 is irradiated on the first liquid crystal mixture 230a, the photoinitiator in the first liquid crystal mixture corresponding to the open hole starts the photo polymerization process by ultraviolet rays.

That is, the ultraviolet ray hardening resin is caused to undergo polymerization reaction around the photoinitiator at the position corresponding to the opening hole of the mask 260, and is changed to a solid state. Accordingly, a part of the first liquid crystal mixture 230a formed between the first upper film 210a and the first lower film 220a is solidified and changed into the second liquid crystal mixture 230b. The control panel of the second liquid crystal mixture 230b is referred to as a second control panel 200b.

Next, referring to FIG. 2 (g), if the ultraviolet (UV) curing process as described above for the second climate control panel 200b is continuously performed, The ultraviolet curable resins that are present are completely cured to form barrier ribs 231. The space enclosed by the barrier ribs 231 is called a cell, and the cell is filled with liquid crystal.

That is, as described above, the photoinitiator is activated by ultraviolet rays to initiate the polymerization reaction of the ultraviolet curable resin. The ultraviolet curing resin in the monomer (monomer) state is transformed into a polymer (polymer) by the polymerization reaction and becomes a solid. These solid state polymers form partition walls 231 inside the third liquid crystal mixture 230c.

Since the mask 260 has an opening in the form of a matrix, the partition 231 is formed in the third liquid crystal mixture 230c at a position corresponding to the opening of the matrix.

The barrier ribs 231 formed in the third liquid crystal mixture 230c function to maintain a gap between the first upper substrate 210a and the first lower substrate 220a and to have a function of holding the first upper substrate and the first lower substrate .

Further, the barrier ribs 231 function to separate the third liquid crystal mixture 230c into respective cells. That is, when the voltage is applied to the transparent electrodes formed on the first upper substrate 210a and the first lower substrate 220a by separating the third liquid crystal mixture 230c into the respective cells by the barrier ribs 231 , The liquid crystals in each cell may be individually operated to implement a wide viewing mode or a narrow viewing mode.

Finally, although not shown in the drawings, the third light control panel 200c, which is continuously formed on the two raw film films 211 and 221, is cut in accordance with the size of the liquid crystal panel, The control panel is completed.

That is, in the present invention, the two raw film films 211 and 221 wound on the rollers are used, and the two raw film films 211 and 221 are processed by the roll-to-roll process . Therefore, the third control panel 200c can be continuously formed on the two raw film films. In this case, the control panel can be finally formed through the cutting process.

However, the present invention is not necessarily formed by a roll-to-roll process. Accordingly, the cut laminated film according to the size of the individual co-op control panel may be completed with the coarse control panel through the above process. In the same manner as in the manufacturing process using the glass substrate, a plurality of third control panels 200c are fabricated through the above process, with the laser cut films cut to a size capable of manufacturing a plurality of control panels, After that, the raw film can be cut to complete the control panel.

The above-mentioned process will be briefly summarized as follows.

The present invention as described above makes use of a film to manufacture an upper substrate or a lower substrate that forms a coherence control panel. Particularly, a method of painting a liquid crystal mixture on a film (P-LC: Painting LC) . Therefore, the present invention can lower the cost of the climate control panel and simplify the manufacturing process.

In order to apply the above-described P-LC method, the present invention firstly polishes the green films 211 and 212 (S102), forms a transparent electrode, Followed by baking / rubbing to form alignment films 213 and 223 (S104)

A first liquid crystal mixture (230a) in which a liquid crystal, an ultraviolet curable resin (monomer) and a photo-initiator are mixed is coated on the alignment film of the lower raw film 221 to be used as a lower substrate.

The first upper substrate 210a is covered with the first lower substrate 220a coated with the LC mixture to laminate two films (S108).

UV light exposure is performed using a mask 260 to form a polymer wall 231 by separating the liquid crystal and an ultraviolet curable material (S110). That is, according to the present invention, ultraviolet rays are passed through an opening hole formed in the mask 260 in the form of a partition wall, thereby forming a partition wall 231 having a shape corresponding to the opening hole.

The polymer wall thus manufactured functions to hold the gap between the upper substrate and the lower substrate while attaching the upper substrate and the lower substrate together.

FIG. 4 is a cross-sectional view illustrating an embodiment of a liquid crystal display device using the unidirectional control panel according to the first embodiment of the present invention, FIG. 5 is a plan view of a liquid crystal display device using the unidirectional control panel according to the second embodiment of the present invention. Fig.

As shown in FIG. 4, a liquid crystal display device using a climate control panel according to a first embodiment of the present invention includes a liquid crystal panel 100 in which a liquid crystal layer is formed between an array substrate and a color filter substrate, A first polarizing film 300 attached to the lower end surface of the panel 100, a second polarizing film 400 attached to the upper surface of the liquid crystal panel, a light source unit 400 disposed at the lower end of the liquid crystal panel, An optical member 700 disposed between the light source unit and the liquid crystal panel to convert the light emitted from the light source unit into a state perpendicular to the liquid crystal panel and applying the converted light to the liquid crystal panel, And a third polarizing film 500 attached to the upper surface of the coarse control panel.

The liquid crystal panel 100 drives the liquid crystal injected between the array substrate and the color filter substrate to a voltage applied to the array substrate and outputs an image by controlling the amount of light emitted from the light source unit 800.

The first polarizing film 300 and the second polarizing film 400 are vibrating in the same direction as the polarization axis formed on the first polarizing film 300 and the second polarizing film 400 among the light emitted from the light source unit 800 And transmits the light only. That is, the light polarized by the first polarizing film 300 passes through the second polarizing film 400 in a state in which the transmission amount thereof is changed while passing through the liquid crystal whose arrangement is changed according to the electric field for each pixel, , Different brightness may be expressed for each pixel. That is, the first and second polarizing films are attached to the upper surface or the lower surface of the liquid crystal panel, and function to pass only components in a specific direction among components of light transmitted from the light source unit 800 .

The light source unit 800 is for outputting light to be applied to the liquid crystal panel 100, and may be composed of various kinds of light sources. In recent years, a light emitting diode (LED) has been widely used as a light source for forming the light source unit 800.

The optical member 700 functions to vertically convert the light emitted from the light source to the liquid crystal panel and apply it to the liquid crystal panel. The optical member 700 may include various sheets including a diffuser sheet, a prism sheet, Lt; / RTI > If the liquid crystal display device according to the present invention is of the meteorological type, a light guide panel (LGP) may be added in addition to the above-mentioned sheets. In the case of a direct light type, a diffusion plate may be further added.

The control panel 200 is manufactured through a process as described with reference to FIGS. 2 and 3. The control panel 200 is mixed with the liquid crystal mixture according to the voltage applied to the upper film 210 and the lower film 220 The alignment direction of the liquid crystal is changed to perform a function of changing the viewing angle.

The liquid crystal mixed in the liquid crystal mixture 230 is oriented so as to be aligned in the vertical direction between the upper film 210 and the lower film 220. That is, the liquid crystal is formed between the upper film 210 and the lower film 220 in an ECB (Electrically Controlled Birefringence) mode or an OCB mode.

When a voltage is applied to the unidirectional control panel 200 according to the present invention, the liquid crystal moves between the upper film 210 and the lower film 220 in a direction perpendicular to the upper film 210 and the lower film 220 .

In this case, if the user looks at the front face of the PD control panel 200, the light passing through the liquid crystal is normally incident on the eye of the user.

However, if the user is looking at the co-op control panel on the side of the co-op control panel 200, the user will not be able to see the light blocked or refracted by the side of the liquid crystal. Therefore, the user can see only a part of the light.

That is, when a voltage is applied to the unidirectional control panel 2000 according to the present invention, a user viewing the unidirectional control panel on the side of the unidirectional control panel 200 can see only a part of the light. .

When no voltage is applied to the unidirectional control panel 200 according to the present invention, the liquid crystal moves between the upper film 210 and the lower film 220 in a direction horizontal to the upper film 210 and the lower film 220 .

In this case, the user on the front face of the panoramic control panel 200 and the user on the side of the panoramic air panel 200 view the liquid crystal panel under the same conditions. Thus, the user on the side of the coarse control panel 200 can also see the same light as the user on the front of the coarse control panel 200. Such a mode is referred to as a wide viewing mode.

Since the functions of the universe control panel 200 according to the present invention are the same as those of the general universe control panel, a detailed description thereof will be omitted.

The third polarizing film 500 functions to transmit only the light that oscillates in the same direction as the polarization axis formed on the third polarizing film 500 among the light passing through the coarse control panel 200. That is, the second polarizing film 400 and the third polarizing film 500 are attached to the lower end surface or the upper end surface of the unidirectional control panel 200, And passes only the components.

5, the liquid crystal display device using the unidirectional control panel according to the second embodiment of the present invention includes a liquid crystal panel 100 in which a liquid crystal layer is formed between an array substrate and a color filter substrate, A first polarizing film 300 attached to the lower end surface of the panel 100, a light source unit 800 disposed at the lower end of the liquid crystal panel to irradiate light to the liquid crystal panel, a light source unit 800 disposed between the light source unit and the liquid crystal panel, An optical member 700 for converting light into a state vertical to the liquid crystal panel and applying the light to the liquid crystal panel, and a clutter control panel 200 according to the present invention attached to the upper end of the liquid crystal panel.

Except for the difference that there is no second polarizing film 400 and third polarizing film 500, the configuration of the liquid crystal display device using the coarse control panel according to the second embodiment of the present invention is the same as the first embodiment Is the same as the configuration of the liquid crystal display device using the coarse adjustment control panel according to the example. That is, in the first embodiment of the present invention, the second polarizing film 400 is attached to the upper end face of the liquid crystal panel, the optical coherence control panel 200 is attached to the upper end face thereof, A polarizing film 500 is attached.

However, in the second embodiment of the present invention, the optical coherence control panel 200 is attached directly to the upper surface of the liquid crystal panel 100.

In the second embodiment of the present invention, the reason why no separate polarizing film is attached between the liquid crystal panel 100 and the coarse control panel 200 is that the coarse control panel The upper raw film film 211 and the lower raw film 221 of the liquid crystal display panel 200 are constituted by polarizing films.

That is, in the present invention, by using a polarizing film as the upper raw film film 211 and the lower raw film 221, the liquid crystal panel 100 and the liquid crystal panel 100, The step of attaching the polarizing film can be omitted. Therefore, the present invention can reduce manufacturing cost and process.

That is, since the process of forming the alignment films 214 and 224 and the polymer wall 231 can be performed at a low temperature of 80 ° C or less, the polarizing film (POL ) Can be used as a raw film to manufacture the climate control panel 200.

FIG. 9 is an exemplary view showing response characteristics of the climate control panel according to the present invention. FIG.

As described above, the nematic liquid crystal and the monomer (RM), which is an ultraviolet ray hardening resin, are mixed to form the viscous liquid crystal mixture 230a, and then the liquid crystal mixture 230a is coated on the orientation film And the first upper film 210a and the first lower film 220a coated with the liquid crystal mixture are laminated. When the ultraviolet rays are irradiated to the first clustering control panel 200a using a mask, liquid crystal / polymer phase separation induction occurs at intervals of several tens to several hundreds of micrometers, and the partition wall 231 is formed in the liquid crystal mixture 200c, The cell is completed.

The inventive clathrate control panel manufactured by the above process can be operated at a low voltage (<10 V) due to the degree of freedom of switching the phase-separated liquid crystal mixture, haze can be reduced, By the phase-separated polymer (polymer), it is possible to maintain a gap between two films.

Meanwhile, FIG. 6 shows the partition 231 and the cell 232 generated by induction of phase separation between the liquid crystal and the polymer. The liquid crystal cells formed in the cells 232 surrounded by the barrier ribs 231 are changed in the arrangement state by the voltage as described above, so that the wide viewing angle mode and the narrow viewing angle mode can be formed.

7 is a diagram illustrating a simulation result of the optical coherence control panel according to the present invention. As shown in FIG. 7, the wide viewing angle characteristic is excellent even in a range of 0 to 50 degrees in the wide viewing angle mode (a) In the mode (b), the viewing angle characteristic is remarkably deteriorated.

8 and 9 are graphs showing electro-optical characteristics of the optical coherence control panel according to the present invention. As shown in FIG. 8, it can be seen that the VT curve characteristic is excellent even when the driving voltage is 10 V or less, As shown in Fig. 9, the response characteristic is also excellent.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
