The embodiments of the present invention are provided to enable those skilled in the art to more fully understand the present invention. Also, in the figures, the thicknesses of the films (layers, patterns) and regions may be exaggerated for clarity. Further, when it is mentioned that the film (layer, pattern) is in the "upper", "upper", "lower", "one side" of another film (layer, pattern) Or a different film (layer, pattern) may be interposed therebetween.

Embodiments of the present invention disclose a removable display device that satisfies aesthetic desires of a consumer by interfacing the design of the screen with the design of the bezel area and providing the thin film printing layer and the hidden layer in the bezel area. A detachable display device having a thin printing layer and a concealing layer in a bezel region will be described in detail with reference to a technical idea of interlocking the design of the screen with the design of the bezel region. Furthermore, a manufacturing method of a removable display device having a digital printing layer and a concealing layer in a bezel region will be described in detail.

The detachable display device of the present invention is limited to being detachably attached to a touch screen and a display, and is clearly distinguished from a conventional window protective film detachably attached to a window. That is, a device consisting of a display without a window or a touch screen is not a complete display device. The display device is completed only when a window or a touch screen is attached. By the way, the window protective film is attached on the window of the present invention, and the window protective film is attached to the already completed display. Accordingly, the window or touch screen of the present invention is an essential component of the display device, but the conventional window protective film corresponds to a supplementary component that can be selectively applied to the display device. Accordingly, window protective films are excluded from the scope of the present invention.

The display device according to the embodiment of the present invention refers to all image processing devices such as a mobile device, an information processing terminal, and a television. The mobile device includes a mobile phone, a smart phone, a tablet, and the like. The information processing terminal includes an ATM, a kiosk, and the like. The display of the display device may be flat or curved, and may be flexible. The image processing apparatus includes a window, a touch screen, and a display. Accordingly, the window generally refers to a window of a mobile device, a window of an information processing terminal, or a window of all image processing devices such as a television. Similarly, the touch screen and the display also refer to a touch screen and a display that are applied to all image processing apparatuses.

FIG. 1 is a view illustrating a display device according to an embodiment of the present invention in a screen direction.

Referring to FIG. 1, the apparatus of the present invention is divided into a screen A and a bezel area B. When the first device 100 is turned off, no design appears on the screen A. The screen design D1 of the screen A and the bezel design D2 of the bezel area B interlock with each other to become the unit design D in the ON state of the screen. Here, interlocking means that the screen design D1 is continuously extended to the bezel area B, so that the screen design D1 is interlocked with the bezel design D2, so that the screen A and the bezel area B are unit- D).

The unit design (D) is expressed using black and white and color colors such as photograph, oil painting, watercolor, ink painting, and drawing, and is treated as one work. Here, one work means that a screen design D1 and a bezel design D2 are interlocked to implement one design, as shown in the figure. In the apparatus of the present invention, when the screen A is turned off, the bezel design D2, which is a part of the unit design D, remains only in the bezel area B.

In some cases, when the screen A is turned off, the concealed design C that is concealed when the screen A is ON can be displayed. As described above, the concealment design C is displayed when the screen A is turned off, and is hidden when the screen A is turned on. The cloaking design (C) may be a logo, a name, a product specification, or the like, such as a letter or a figure. The brightness and saturation of the concealment design can be adjusted so that the concealment design C does not appear in the ON state. The concealment design C of the screen A may be interlocked with the bezel area B when the screen is in the ON state. Thus, the concealment design C can be a unit concealment design (C) like the unit design D.

The screen design D1 is an uploaded download through an application or the like, or uploaded to the display device. That is, the user downloads the screen design D1 expressed by utilizing various colors such as photographs, oil paintings, watercolors, ink paintings, drawings, and the like using the application or the like. The display device of the present invention includes a bezel design D2 interlocked with the screen design D1 to implement the unit design D as a whole.

Hereinafter, the display device of the present invention will be described with reference to the bezel area B of FIG. Specifically, the first device 100 is detachably attached to the touch screen, and the second device 200 is detachably attached to the display. Embodiments of the present invention provide examples of first and

second devices

100 and 200, but may also be applied to other types of display devices within the scope of the present invention. At this time, the process of attaching and detaching can be performed manually.

2 is a cross-sectional view showing a first bezel region B1 of a first device 100 according to an embodiment of the present invention. However, the first device 100 in the strict sense is not represented, and for convenience of explanation, there may be elements not shown in the drawings.

2, the first bezel region B1 includes a transparent sheet 10, a thin film printed layer 11, an adhesive layer 12, a hiding layer 13, a scattering prevention film 14, a removable layer 15, The adhesion reducing layer 16, the touch screen 17 and the display 18 are sequentially stacked. At this time, the positions of the attachment / detachment layer 15 and the adhesion reduction layer 16 may be mutually changed. The adhesion reducing layer 16 is located on the anti-scattering film 14, and the adhesion-removing layer 15 is located on the touch screen 17.

The transparent sheet 10 can be used without restrictions as long as it is made of a transparent material, and serves as a window in the first device 100. For example, a glass substrate or a plastic substrate. Specifically, the glass substrate may be tempered glass, and the plastic substrate is made of a thermoplastic resin. Preferably, the plastic substrate is made of PET (PolyEthylene Terephthalate), PEN (PolyEthylene Naphthalate), PES (Polyether Sulfone) ), PC (PolyCarbonate), PMMA (PolyMethyl Methacrylate), PU (Polyurethane), TAC (Tri-Acrylic-Cellulose) or COC (Cycloolefin Copolymer). Tempered glass is more preferable. The transparent sheet may be a laminated structure in which the reinforcing glass and the plastic substrate are formed in multiple layers.

On the transparent sheet 10, properties such as prevention of fingerprints, prevention of reflection, blocking of blue light, blocking of electromagnetic waves, privacy, and antibacterial property can be given. For example, a fluorine-based coating liquid may be wet-coated, or may be dry-coated by vacuum deposition to form a fingerprint-preventing coating layer that provides a fingerprint-proofing function. The coating layer of the transparent sheet 10 may be a glass substrate which has been subjected to anti-fingerprinting or anti-fingerprinting and antibacterial treatment, or a plastic substrate which has anti-fingerprinting or anti- As such, the coating allows the transparent sheet 10 to exhibit various functions. Alternatively, the transparent sheet may employ a slim tempered glass having a thickness of approximately 10 mu m to 150 mu m. The slim tempered glass has a breakage mechanism that causes cracks that do not involve debris. Since there are no scattered fragments and no sharp edges, there is no debris that injures or injures the user or is sucked into the human body. The slim tempered glass is free from warpage, and is more efficient especially when applied to the screen area of the second type.

The thin film printing layer 11 is printed on the transparent sheet 10 with the bezel design D2 printed with the screen design D1 interlocked. The screen design D1 and the bezel design D2 combine to form a unit design D. The unit design (D) is expressed using black and white and color colors such as photographs, oil paintings, watercolors, ink paintings, and drawing.

Printing of the thin film printing layer 11 can be performed in various manners. For example, it is preferable to print by a silk screen method, an offset printing method, a lithographic printing method or the like, or a digital printing method. The digital printing is a method in which ink containing various colors is ejected at one time and printed on the transparent sheet 10. On the other hand, the silkscreen method and offset printing have to be performed several times, and the lithography printing uses masks. The thin film printed layer 11 additionally serves to prevent scattering of the transparent sheet 10 when the transparent sheet 10 is broken.

Substantially, the silk screen method, offset printing, and lithographic printing are relatively thick in the thin-film printing layer 11, but digital printing is relatively thin and suitable for the thin-film printing layer 11 of the present invention. This is because the thickness of the thin film printing layer 11 is preferably 5 to 100 占 퐉 in consideration of the total thickness of the first device 100 and the sharpness of the design. If the thickness is less than 5 탆, the bezel design becomes poor in sharpness. If it is more than 100 탆, the thickness of the thin-film printed layer 11 is excessively large. The use of silkscreen process, offset printing, lithographic printing may complicate the process, thicken the first device 100, and may substantially degrade the sharpness of the bezel design. Accordingly, the use of a silk screen method, offset printing, or lithographic printing is not excluded, but a digital printing layer by digital printing is more preferable.

The adhesive layer 12 may be any one selected from, for example, a thermosetting resin which is an acrylic resin, a silicone resin or a urethane resin or a pressure-sensitive adhesive in which a crosslinking agent is mixed with an ultraviolet curing resin, a mixture thereof or a copolymer thereof. The concealing layer 13 improves the concealability of the thin-film printed layer 11 so that the image of the thin-film printed layer 11 is clearly displayed. The shielding layer 13 may be a white ink layer coated with a white ink or a metal thin film deposited with a metal material having excellent reflectivity. The whiteness of the white ink layer can be controlled by adding a trace amount of a pigment other than white.

The white ink may be any ink including a binder, a pigment, a dispersant, and a solvent. At this time, the binder is for fixing the pigment in the white ink to the anti-scattering film 14 and may include an acrylic resin. The pigment may be a white colorant such as titanium dioxide, talc, clay and the like. The dispersant disperses the pigment uniformly, and the solvent is composed of a component that dissolves the solute to form a solution. The white ink may further include a thickener, and the thickener serves to increase the viscosity of the ink, and the white ink may be adjusted to have a viscosity similar to that of the white gravure ink.

The metal thin film is formed by physical vapor deposition or chemical vapor deposition, and preferably physical vapor deposition is preferable. The physical vapor deposition may use various methods such as electron-beam, ion-beam, sputtering, and excimer laser. The metal may be at least one layer selected from the group consisting of Al, Ag, Cu, Au, Pt, Pd, Rh, Ni, W, Mo, Cr, Sn and Ti or a composite layer thereof. Suitably, it is made of either Ag or Al or an Ag-Al alloy. The metal thin film may be directly deposited on the anti-scattering film 14 or may be transferred by transferring the metal thin film.

The metal thin film of the present invention preferably has a reflectance of 70% or more at a wavelength of 350 nm to 400 nm including a visible light region. Substantially Ag and Al have a reflectance of 80% or more in the visible light region. However, if the thickness (T _d ) of the metal thin film is too small, the light transmittance may become large, so that the relationship between the reflectance and the thickness (T _d ) of the metal thin film can be appropriately set. Preferably, the thickness (T _d ) of the metal foil may range from several hundreds to several thousands of angstroms. Since the relationship between the reflectance and the thickness is known, a detailed description thereof will be omitted.

The first bezel area B1 according to the embodiment of the present invention improves the sharpness of the bezel design D1 by combining the thin film printing layer 11 and the concealment layer 13. [ If there is no concealing layer 13, the bezel design D1 is implemented only with the thin-film printing layer 11. The thin film printing layer 11 is not concealed so that the color and shape of the lower touch screen 17 and the display 18 are transmitted and the image of the bezel design D1 is not clear. The shielding layer 13 shields the color and the shape of the lower touch screen 17 and the display 18 from being transmitted so that the image of the bezel design D1 is clearly displayed.

The shatterproof film 14 is preferably a film of a thermoplastic resin and may be formed of a material such as PET (PolyEthylene Terephthalate), PEN (PolyEthyleneNaphthalate), PES (PolyetherSulfone), PI (Polyimide), PAR (Polyarylate) And may be made of at least one selected from PMMA (PolyMethylMethAcrylate), PU (PolyUrethane), TPU (Thermal PU), PE (PolyEthylene), PP (PolyPropylene), TAC (Tri- Acyltyl-Cellulose) or COC (Cycloolefin Copolymer) .

Adhesive strength of the detachable layer 15 is preferably about 0.1 gf / 25 mm to 500 gf / 25 mm, more preferably 0.2 gf / 25 mm to 50 gf / 25 mm. This is smaller than the conventional adhesive force of 1,500 gf / 25 mm of the conventional adhesive layer, and thus is distinguished from the conventional adhesive layer. Here, the adhesive layer 15 of the present invention is an optically transparent adhesive which is cured by heat treatment or UV (ultraviolet ray). The adhesive is cured to a semi-solid state by heat treatment or UV treatment at a predetermined temperature and time. The adhesive method can be easily hand-woven by the user without air bubbles.

The adhesive layer 15 may be variously used within the technical spirit of the present invention, but it is preferable to use an acrylic polymer, a silicone polymer, a urethane polymer, an adhesive mixed with a UV curing resin and a crosslinking agent, or a mixture thereof or a copolymer thereof. In some cases, a functional material such as silica gel, nanoparticles, and an antistatic agent may be mixed with the release / release layer 15 to improve the physical properties of the release / release layer 15. Furthermore, the quantum dots may be added to the release layer 15 to improve optical characteristics.

To facilitate detachment and attachment, an adhesion reducing layer 16 may be added. The adhesion reducing layer 16 lowers the frictional force and increases the slip property. By the adhesion reducing layer 16, the detachable layer 15 is easily detached and attached. As the adhesion reducing layer 16, a coating material of a fluorine resin or a silicone resin can be used. The adhesion reducing layer 16 may be formed by depositing titania (TiO ₂ ) or silica (SiO ₂ ) on the touch screen 17 and then coating a fluorine resin or a silicone resin on the deposited touch screen 17 . At this time, the fluororesin or silicone resin can be formed by an ECC (Easy Cleaning Coating) method. When the adhesion reducing layer 16 is applied, generation of bubbles can be more effectively suppressed when the attachment / detachment layer 15 is attached. In addition, the adhesion reducing layer 16 allows the consumer to easily attach and detach without any additional tool.

The adhesion reducing layer 16 may be formed on all or part of the fine irregularities. The formation of the fine irregularities in a part is referred to as an adhesion reduction layer pattern. In addition, the adhesion reducing layer 16 may include patterns made of fine irregularities. The fine irregularities are not transparent compared to the portions without fine irregularities. However, when the adhesion reducing layer 16 adheres to the detachable layer 15, the detachable layer 15 fills the space between the fine irregularities Transparency is restored. That is, the fine irregularities are regularly or irregularly wholly or locally contained in the adhesion reducing layer 16.

The touch screen 17 has a conductive pattern formed on one side or both sides of an insulating layer made of metal oxide or plastic. Metal oxide is mainly used for the conductive pattern, and metal oxides include ITO, ATO, ZnO, Cu, conductive polymer, or silver nanowire. The display 18 is applied to the above-described display device, and includes a liquid crystal display (LCD), an organic light emitting diode (OLED), an electrophoretic display (EPD), and the like.

On the other hand, at least one of the thin film printing layer 11 or the hiding layer 13 may include at least one of a light emitting body such as a phosphor and a phosphorescent body. When the energy is received by the external light, the electric field, the electron beam, the heat, the physical force, etc., the electrons are excited and transition to a high energy level. When the electron falls from a high energy level to a low energy level, . Such luminous bodies include various materials such as nitride, titanate and the like.

The phosphorescent material absorbs light having a relatively high energy level, such as sunlight, and then reduces the visible light to a low-level visible light. The phosphorescent material has a property of emitting light even in a dark place for a long time. Examples of the phosphors include various kinds of alkaline earth metal aluminate based sulphides such as ZnS: Cu, CaS: Bi, (Ca, Sr) S: Cu, (Zn, Cd) S: Cu, In particular, utilization of oxides based phosphors which are chemically and environmentally stable is increasing. The oxide system is, for example, a strontium-aluminum oxide system (Sr-Al-O system) phosphorescence material to which a rare earth material is added as an activator. The Sr-Al-O-based phosphorescent material can exhibit light emission characteristics of various wavelength ranges through the inherent excitation characteristics of the activator. By mixing the phosphors, light is absorbed during the day, and then emitted as visible light at night, thereby emitting light.

Mixing at least one of the thin film printing layer 11 or the concealing layer 13 with any one of a phosphor or a phosphorescent material or a mixture thereof to serve as a marker in a dark place by luminescence and add a sense of aesthetics. This is because it is difficult to confirm the position of the first device 100 in a dark place. However, the position of the first device 100 can be accurately confirmed even in a dark place by any one of the luminous body or the luminous body of the present invention or a mixture thereof. Of course, the content in which the luminous body or the phosphorescent material is mixed is determined within a range that does not impair the sharpness of the bezel design (D2) of the present invention.

The source of the unit design (D) according to an embodiment of the present invention may be provided by a platform, a consumer, a designer, or the like. That is, the source may allow a consumer or a designer to upload a design such as his or her photograph to the platform. Accordingly, the design source according to the embodiment of the present invention is not limited.

6 is a flowchart illustrating a process in which a display device according to an embodiment of the present invention is sold to a consumer. In this example, the consumer is using the platform.

Referring to FIG. 6, a consumer selects a desired design source in a platform using a classification scheme or a classification scheme provided by a platform (S10). At this time, the design source may be provided by a platform, a consumer, or a designer. Then, when a design source is selected, the design source can be corrected if necessary (S12).
