More particularly, the filter is directly attached to the front substrate of the plasma display device to improve interface characteristics and dual image phenomena, The present invention relates to a film filter for reducing manufacturing costs and a plasma display device having the same.

As is well known, plasma display panels can satisfy both size and thickness at the same time as CRTs representing conventional display apparatuses, and thus are attracting attention as next generation display apparatuses.

However, such a plasma display panel emits strong near infrared light due to its driving characteristics. The near infrared light may affect the operation of a cordless telephone or a remote controller and cause a malfunction.

In addition, the plasma display panel generates strong electromagnetic waves, and since these electromagnetic waves also affect the human body or other electronic devices, it is required to adjust them below the legal threshold.

To this end, the plasma display panel is provided with a front filter that can shield the near infrared rays and electromagnetic waves and reduce the reflected light caused by external lighting. Since the front filter is mounted on the front part of the PDP, transparency must be satisfied at the same time. All.

Meanwhile, conventional PDP filters developed to satisfy each of these characteristics may be classified into a metal mesh type and a transparent conductive film type. First of all, the mesh type PDP filter has excellent characteristics in shielding electromagnetic waves, but there is a problem that the transparency may be degraded or the screen may be distorted. Since the mesh itself is expensive, the overall price of the product increases. There is this.

In general, the surface treatment technology of the display film refers to a technology that processes the entire surface of the panel in various ways in order to minimize the deterioration of the glare and resolution due to external light reflection, and to prevent shock caused by static electricity.

In the conventional plasma display apparatus, there is a problem in that an image is reflected twice by a refractive phenomenon due to a difference in the material between the panel top glass and the tempered glass filter.

In addition, because the tempered glass filter maintains a certain thickness to withstand external shocks, there was a problem of increasing weight and unreasonable cost increase. In addition, the structure of the conventional tempered glass filter has a very complicated structure consisting of a complex of films to perform a variety of functions there was a problem that the manufacturing process is cumbersome and expensive.

Accordingly, the technical problem to be achieved by the present invention is to have all the functions of a tempered glass filter having a complex structure in a thin film, and thus, a direct-attach film filter for plasma display panel, which can be manufactured at a lighter thickness and at a lower cost than a conventional filter. To provide.

In addition, another technical problem to be achieved by the present invention is to improve the interfacial characteristics of the existing filter by applying a direct-attachment MRT film filter, thereby improving the dual image phenomenon, the direct-attachment MRT film applied MRT film with improved clear contrast To provide a filter.

The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. In the drawings, the size or thickness of films or regions is exaggerated for clarity.

Preferably, polycarbonate (PC), polyethylene terephthalate (PET, polyethyeleneterepthalate), cellulose tri acetate (TAC), polyethylene naphthalate (PEN, polyethyelenen napthalate).

In addition, the base film 3 may be characterized by being transparent, which does not mean completely transparent, but means a transmittance that can be seen as transparent in the art.

On the other hand, the conductive layer 5 is comprised in the lower surface of the base film 3.

The conductive layer 5 is used for shielding electromagnetic waves and blocking near infrared rays, which are harmful to a human body generated in the plasma display device. In particular, malfunctions of peripheral electronic devices are problematic due to near infrared rays. In order to solve this problem, near-infrared shielding is required.

In the drawing, the conductive layer 5 is illustrated as one layer, but in the exemplary embodiment of the present invention, the conductive layer 5 may be a structure in which at least two or more layers are stacked in multiple layers as well as the case where the conductive layer is formed as a single layer.

By laminating in multiple layers, the surface resistance value can be corrected and the visible light transmittance can be controlled.

In addition, the conductive layer 5 can employ | adopt a metal layer, a metal oxide, a conductive polymer, etc.

Metal layers include palladium, copper, platinum, rhodium, aluminum, iron, cobalt, nickel, zinc, ruthenium, tin, tungsten, and iridium ), Lead, silver (Ag) and the like can be employed respectively or in combination.

The metal oxide may include at least one of tin oxide, indium oxide, antimony oxide, zinc oxide, zirconium oxide, titanium oxide, magnesium oxide, silicon oxide, aluminum oxide, metal alkoxide, indium tin oxide, ATO, and the like.

Although the anti-reflection layer 1 is shown in one layer in the figure, it may be composed of a multilayer film laminated at least one or more layers.

In addition, as a method of laminating | stacking, the dry coating method (henceforth a dry method), the wet coating method (hereafter, a wet method), etc. can be used.

The dry method is a method of forming an antireflection layer on a substrate by vapor deposition, sputtering or the like. Since the drying method can produce a film made of a single material, the characteristics of the material (for example, refractive index, conductivity, hardness, etc.) can be effectively utilized. In addition, there is a feature that the thickness precision of the film is high.

On the other hand, the wet method is a method in which a liquid material is applied to a substrate and cured as necessary to form an antireflection layer. The wet method is easier to cope with higher productivity, lower cost, and large area than the dry method, and has a high degree of freedom of film material. On the other hand, there is an advantage in that the functionalization is relatively easy, while inferior in terms of characteristics.

In brief, the principle of antireflection is that the visible light reflected from the surface A of the antireflection layer 1 and the interface B between the antireflection layer 1 and the base film 3 has a phase on the A and B surfaces. It is a principle that causes the disappearance interference phenomenon by changing to reverse.

In the present embodiment, although the antireflection layer 1 composed of a single layer is provided, it is, of course, within the scope of the present invention within a range having an antireflection function even if the antireflection layer 1 is composed of two or more layers.
