Description

Black Frame Structure of Plasma Display Pane of Filter and Method of making therof}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel, and more particularly, to a black frame structure of a plasma display panel filter and a method of forming the same for enhancing the luminous effect on portions other than an effective screen on the filter of the plasma display panel.

In general, a plasma display panel (PDP) is an image display device using plasma discharge of an inert gas in a micro space having a length of about 0.1 mm to 1 mm, and is easy to manufacture due to its simple structure, and is thin in shape and low in consumption. It is a trend that is attracting attention because of its features such as power.

1 is a perspective view schematically illustrating a structure of a general plasma display panel. As shown in the drawing, the PDP first includes a case 100 for determining an appearance, a driving circuit board 200 accommodated in the case 100, and a panel module 300 in which plasma discharge occurs on the driving circuit board 200. ) And a filter 400 formed by attaching a film to a transparent glass substrate (not shown) at a predetermined distance to the front surface of the panel module 300.

Since the plasma display panel having such a structure implements an image by applying a high voltage and a high frequency for plasma discharge, the electromagnetic wave is emitted from the panel front panel 400 more than a color cathode ray tube (CRT) or a liquid crystal display panel (LCD). There is a need for means with better electromagnetic shielding capabilities. In addition, the plasma display panel emits near-infrared (NIR) induced from an inert gas such as Ne and Xe to the front. This near-infrared ray is very close to the wavelength of a remote controller of a home appliance, which may cause a malfunction. Therefore, there is a need for a means having a function of blocking the near infrared. In addition, there is a need for means having an anti-reflection function in order to prevent glare from external light as in a CRT or LCD.

For this reason, in a typical plasma display panel, a functional filter having a predetermined function is formed on the front surface of the panel.

2 is a schematic diagram showing the structure of a functional filter of a conventional plasma display panel. As illustrated, a first functional film, that is, an antireflection film layer (AR Film) 410 is formed on the transparent glass substrate 420 formed at a predetermined distance from the panel module 300, and the transparent glass substrate ( A second functional film that controls near-infrared (NIR) shielding and color adjacent to 420, that is, a color die film layer (Color-dye, 440), a third functional film, that is, an electromagnetic wave shielding film layer (EMI Film, 450) ) Are formed sequentially to form the filter 400. When the viewer looks at the screen, the filter formed in this way forms a ruler by treating a portion of the transparent glass substrate 420 other than the effective screen in black in order to increase the viewing effect. It is referred to as (430).

Unlike the plasma display panel in which the black frame is formed on the glass substrate at a predetermined distance from the panel assembly as shown in FIGS. 1 and 2, in the case of the module-integrated plasma display panel in which the filter is directly attached to the front panel of the plasma display module, the film is black. It was common for the frame to be attached directly to the plasma display front panel.

3 is a schematic view showing the structure of a conventional module integrated plasma display panel. As shown, the module integrated plasma display panel has a black frame 430 directly attached to the front panel 310, and a third functional film, that is, an electromagnetic shielding film layer 450, on the upper surface of the black frame 430. ), A second functional film, that is, a color die film layer 440, and a first functional film, that is, an antireflection film layer 410, are formed.

In such a conventional module-integrated plasma display panel, a predetermined process is required separately to form a black frame. In addition, due to a separate process, there was a problem that the work process time is delayed.

Accordingly, the present invention provides a black frame structure of a plasma display panel filter that can distinguish between an effective screen and an invalid screen, improve viewers' visibility, and improve workability of a black frame in order to solve the above problems. The purpose is to provide a formation method.

In order to solve the above technical problem, the present invention is a black frame structure of a plasma display panel filter having a functional filter including at least one functional film and a base film on the front panel of the plasma display module, the functional film and the base film A black frame structure of a plasma display panel filter is provided, wherein a black frame is formed on at least one unit filter among the stacked unit filters.

Another feature of the present invention is a plasma display panel filter having a filter bonded by an adhesive by stacking a plurality of film layers having a predetermined functional film attached to an upper surface of a base film, wherein at least one of the layers formed by the base film or the adhesive is formed. The present invention provides a method for forming a black frame of a plasma display panel filter, wherein the black frame is formed by irradiating ultraviolet light to one layer.

In still another aspect of the present invention, there is provided a method for manufacturing a black frame of a plasma display panel filter having a functional filter including at least one functional film and a base film on a front surface of the plasma display module, wherein the first functional film is disposed on an upper surface of the first matrix film. Forming a first unit filter by coating a second unit film, and forming a second unit filter by applying a second functional film on an upper surface of the second base film, wherein the first unit filter and the second unit filter are black. A method of manufacturing a black frame of a plasma display panel filter comprising attaching each other through an adhesive including a pigment to form a filter, and exposing the filter to which the first unit filter and the second unit filter are attached. to provide.
