BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat panel display device, and more particularly, to a flat panel display device, a film filter, and a method of manufacturing the same for improving and protecting optical properties of a panel.

In general, a flat panel display panel is used for a display device having a thin structure, and representative examples thereof include a liquid crystal display (LCD), an organic light emitting diode (OLED) display, and a plasma display panel ( Plasma display panel (PDP) and field emission display (FED).

Among them, PDP is a type of light emitting device that displays an image by using a discharge phenomenon, and there is no need to mount an active device for each cell, so the manufacturing process is simple, the screen is easy to enlarge, and the response speed is fast. It is attracting attention as a display element of the image display apparatus which has a screen.

In the flat panel display panel such as the PDP, a filter for performing various functions is positioned on the front surface of the screen.

The function of the filter includes a color correction function for preventing reflection, improving contrast, and selectively absorbing such wavelengths when high visibility is observed at a specific wavelength.

Examples of such a filter include a glass filter disposed at regular intervals from the panel, a clear filter (film filter) attached to the front surface of the panel by an adhesive layer, and the like.

1 shows the structure of such a film filter. That is, the film filter is attached to the front glass 10 of the panel, and the anti-reflection layer 20 and the color correction layer 40, and the electromagnetic interference (EMI) to improve the optical characteristics ) May include an electromagnetic wave shielding layer 30.

The antireflective layer 20, as shown in Figure 2, on the PET film 21, a hard coating layer 22 for strength enhancement is located, on this hard coating layer 22, a high refractive index (23) layer And a low refrective index (24) layer in order to prevent reflection, and the PSA (pressure sensitive adhesive: 25) for adhesion below the PET film 21 is located.

In addition, as shown in FIG. 3, the electromagnetic wave shielding layer 30 has an adhesive layer 32 on the PET film 31, a copper mesh layer 33 on the adhesive layer 32, and the non-reflective layer. Like (20), a pressure sensitive adhesive (PSA) 34 for adhesion is located under the PET film 31.

As shown in FIG. 4, the color correction layer 40 has a coating layer 42 having a color correction function on the PET film 41, and a PSA for adhesion to the front surface of the panel below the PET film 41. (pressure sensitive adhesive: 43) is placed. At this time, since the PSA 43 surface is directly bonded to the panel, a PSA 43 that can be reworked is used.

As described above, the antireflective layer 20, the electromagnetic shielding layer 30, and the color correction layer 40 forming the filter of the display panel each have three to five layers, and thus, a total of 12 or more multi-layered layers. It consists of, the production of such a filter requires a number of processes.

In addition, the antireflective layer 20, the electromagnetic wave shielding layer 30, and the color correction layer 40 are all repeatedly used in common with the PET films 21, 31, 41 and PSAs 25, 34, 43. In addition, since these materials are expensive materials, the manufacturing cost increases accordingly.

In addition, a flat panel display panel using such a film filter has a disadvantage of being vulnerable to impact from the outside. In addition, as the display panel becomes larger, such an impact becomes more problematic.

In particular, since the front surface of the PDP and the like may be relatively firm as compared to a display panel such as an LCD, breakage due to carelessness of a user may occur frequently.

Such a film filter is used by directly attaching a film filter to the front of the display panel as described above, the impact can be absorbed by the PET film constituting such a film filter, but the effect is weak.

In addition, the surface of the film may be deformed or fine cracks may be generated in the process of adhering the filter, thereby reducing the smoothness of the screen.

On the other hand, as shown in FIG. 5, the glass filter is provided with the anti-reflective layer 20, the electromagnetic shielding layer 30, the color correction layer 40, and the like on a separate glass substrate 50. Likewise, each layer comprises a PET film and a PSA.

Since such a glass filter uses tempered glass as a substrate, the protection from an external impact can be excellent. However, due to the weight of the tempered glass as the protective film, not only the weight of the entire display device is greatly increased, but also the optical characteristics such as the occurrence of a double reflection image may be degraded.

As described above, the optical filter used in the flat panel display device uses expensive materials, requires a lot of processes for manufacturing, has a weak strength, and therefore, it is difficult to realize low cost and does not sufficiently protect the panel.

The technical problem of the present invention is to solve the problems as described above, it is possible to reduce the price by implementing the function of the filter in a small number of layers, and such a filter to perform a protective function of the panel and It is intended to provide a film filter and a method of manufacturing the same.

The flat panel display panel includes a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a plasma display panel (PDP), a field emission display (FED), and the like. This can all apply.

The light transmission control layer is formed of an organic material containing at least one of a near-infrared absorbing pigment, a near-ultraviolet absorbing pigment and a color correction pigment. desirable.

The light transmission control layer is preferably formed by applying directly to the entire surface of the panel using a resin.

In addition, the anti-reflection layer, and the adhesive layer attached on the light transmission control layer; A film positioned on the adhesive layer; A cured layer on the film; It is preferable to comprise at least any one or more of the high refractive index layer and the low refractive layer which are located on the said hardened layer.

As a second aspect for achieving the object of the present invention as described above, the present invention, a flat panel display panel; An electromagnetic shielding layer formed on the front surface of the panel; Located on the electromagnetic shielding layer, it is achieved by including a light transmission control layer for selectively adjusting the transmittance of the light emitted from the panel.

The electromagnetic shielding layer may be directly formed on the entire surface of the panel, and preferably, a net structure of a conductive material or a laminated structure of a metal layer and a transparent conductive layer.

As a third aspect for achieving the object of the present invention as described above, the present invention, a filter comprising an adhesive layer, and a light transmission control layer located on the adhesive layer; It is achieved by including a film attached to at least one side of the filter.

It is preferable that the film is usually made of a PET film available and removable so that it can be easily attached to the panel after removing the film.

The light transmission control layer of the filter may be formed of a resin containing at least one of a near infrared absorption pigment, a near ultraviolet absorption pigment, and a color correction pigment.

An electromagnetic wave shielding layer may be further included between the adhesive layer and the light transmission control layer of the filter, and may further include an antireflection layer on the light transmission control layer of the filter.

As a fourth aspect for achieving the object of the present invention as described above, the present invention, forming an electromagnetic shielding layer on the front surface of the flat panel display panel; Applying a light transmission control layer on the electromagnetic shielding layer; It is achieved by comprising a step of curing the applied light transmission control layer.

The light transmission control layer is preferably formed using a polymer containing at least one of a near infrared absorption pigment, a near ultraviolet absorption pigment, and a color correction pigment.

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

As shown in Fig. 6, the configuration of the flat panel display device of the present invention is largely as follows.

First, an electromagnetic shielding layer 400 is disposed on the front upper plate 110 of the flat panel display panel 100 to shield an electromagnetic interference (EMI) phenomenon caused by electromagnetic waves generated in the panel 100.

As described above, the flat panel display panel 100 is a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a plasma display panel (PDP), a field emission display (FED: field emission display) can be applied.

In particular, the electromagnetic shielding layer 400 may be directly formed on the front upper plate 110 of the panel 100.

In addition, the top plate 110 of the panel 100 may be a conventional glass surface, but may be a synthetic resin or other filter surface in some cases.

The electromagnetic shielding layer 400 may effectively shield electromagnetic waves generated by the driving of the panel 100. In this case, the electromagnetic shielding layer 400 needs to be grounded to a case of a display device.

In the above-described driving of the PDP, in order to maintain the light emission of the panel 100, a sustain discharge must occur at a frequency higher than or equal to a predetermined frequency. This happens.

Since a high voltage of approximately 180 V or more is applied to the discharge, electromagnetic waves generated by the high voltage discharge are removed from the electromagnetic shielding layer 400.

The electromagnetic wave shielding layer 400 can efficiently remove electromagnetic waves generated when the panel 100 is driven, and the upper plate 110 of the panel 100 without the need for a PET film as a mother and a PSA for adhesion. Since it can be formed directly on the top, it is possible to reduce the number of processes and costs, and to prevent the use of expensive materials such as PET film repeatedly.

The light transmission control layer 200 may be positioned on the electromagnetic shielding layer 400 to selectively adjust the transmittance of light emitted by the driving of the panel 100 or to adjust the color tone of the panel 100.

The light transmission control layer 200 may include a color correction function for correcting a specific color tone of the panel 100. That is, the color correction function is to allow the panel 100 to selectively absorb the light having the wavelength when the visibility is high at a specific wavelength.

As an example of the color correction function of the light transmission control layer 200 as described above, the light transmission control layer 200 may contain a dye that absorbs light in the wavelength range of 570 to 590 nm to block yellowing (Neon-cut). ), Or may contain a dye absorbing light in the wavelength range of 380 to 430 nm to block the blue-purple color tone.

In addition, display devices such as PDPs emit ultraviolet rays harmful to the human body, and may emit near infra-red (NIR), which may cause malfunctions of various electronic products operated by a remote controller. In addition, invisible light absorption functions such as near infrared absorption and near ultra-violet (NUV) absorption are included in the light transmission control layer 200.

The light transmission control layer 200 may be prepared by including the above-described pigment in an organic material, and may be formed as a single layer without the need for a PET film, PSA for adhesion, and the like. Therefore, it is possible to reduce the number of processes and costs, the thickness can be appropriately adjusted, and to prevent expensive PET film, PSA for adhesion is repeatedly used.

In addition, the pigment included in the light transmission control layer 200 may be appropriately selected and included as necessary. Therefore, in addition to the pigments for near-infrared blocking, near-ultraviolet blocking, and neon light blocking as described above, when the panel 100 has a specific color tone, it is also easily implemented in selectively including a pigment for removing such color tone. This is possible.

The light transmission control layer 200 may be formed by directly applying to the top plate 110 of the panel 100 by including the pigment as described above in the resin in the visible light band, or having a transmittance of at least 80% or more. It is.

In general, a matrix such as a PET film used in the prior art is expensive and difficult to form at any thickness, but the thickness of the organic material constituting the light transmission control layer 200 of the present invention is enough to protect the panel 100. It can be formed to a sufficient thickness.

The thicker the thickness of the light transmission control layer 200 is, the greater the function of protecting the panel 100 is, but the transparency of the panel 100, the smoothness of the light transmission control layer 200, and the thickness of the entire display device are increased. In consideration of the above, it is preferable to achieve a thickness of 100 μm to 10 mm.

That is, in order to have sufficient strength of the light transmission control layer 200, it is preferable to form a thickness of at least 100 μm or more, and preferably to be thick enough, but usually, when the thickness reaches about 10 mm, sufficient strength may be reached.

The light transmission control layer 200 as described above may be formed on the front top plate 110 of the panel 100 with an appropriate thickness, and has sufficient strength so that the top plate 110 of the panel 100 may be impacted or scratched. To protect against

The anti-reflection layer 300 is provided on the light transmission control layer 200 to prevent the panel 100 from being reflected by external light so that the image is not obscured.

The anti-reflection layer 300 may be formed directly or attached to the light transmission control layer 200.

The antireflection layer 300 includes at least a high refractive index layer and a low refractive layer, and the high refractive index layer and the low refractive layer may be alternately repeatedly positioned. The anti-reflection layer 300 prevents reflection of external light by the difference in reflectance between the interfaces of the high and low refractive layers.

In FIG. 12, a film 610 that can be removed on one or both sides of the filter 500 including at least one of the light transmission control layer 200, the antireflection layer 300, and the electromagnetic shielding layer 400 as described above. It is shown to form a film filter 600 having a (see Fig. 16).

Since the film filter 600 is protected by the film 610, it can be rolled and stored in a roll shape and can be stored and moved.

In order to attach the film filter 600 to the panel 100, the film 610 is removed and attached to the panel 100 to attach the light transmission control layer 200, the antireflection layer 300, and the electromagnetic wave as described above. The shielding layer 400 can be easily formed in the panel 100.

The electromagnetic wave shielding layer 400, the light transmission control layer 200, and the antireflection layer 300 constituting the filter 500 of the film filter 600 are flexible, and in particular, the light transmission control layer 200 is at an appropriate level. Since it is made of a hardened material, it can be used in the form of a roll.

At this time, the thickness of the light transmission control layer 200 of the filter 500 is preferably 500 to 2000㎛.

That is, since the film filter 600 is not formed directly on the panel 100 and must be separately stored or transported, the light transmission control layer 200 of the filter 500 preferably has a thickness of at least 500 μm or more. Since it is used in the form of a roll, the maximum thickness is preferably about 2000 μm (2 mm).

Since the light transmission control layer 200 has sufficient strength, the upper plate 110 of the panel 100 may be protected from external impact or scratches.
