Description

Multi-Screen Plasma Display Device {Plasma display Device for Multi-screen}

The present invention relates to a multi-screen plasma display device, and more particularly, to improve the structure of the seam area, thereby minimizing the appearance of the seam area on the screen by refracting an image of an adjacent panel above the seam area. The present invention relates to a plasma display device.

Recently, various flat panel display panels have been developed and commercialized. Among them, a plasma display panel, a liquid crystal display panel, an organic EL, and the like are representative.

However, these flat panel display panels are limited in implementing a large screen as a single panel. Therefore, a method of composing one multi-screen by combining several unit panels has been proposed.

In particular, the plasma display panel has a structure in which an upper substrate on which X electrodes and Y electrodes are formed and a lower substrate on which address electrodes are formed are sealed, and four panels 10, 12, 14, and 16 are formed as shown in FIG. 1 to form a multi-screen. This can be assembled.

The panels of FIG. 1 are manufactured by a separate manufacturing process in which the upper and lower substrates 20 and 22 are manufactured, respectively, and then the sealing is made by the sealing part 24, and the cutting is performed. In particular, the side adjacent to the other panel is cut along the line where the sealing is made, the side of which is protected by the buffer member (26).

When the panels are assembled by the above-described configuration, as shown in FIG. 2, an area between adjacent panels, that is, a region in which the buffer member 26 is in contact, forms a core region 30 in which an image is not formed.

The core region 30 that divides each panel in a state where a plurality of panels are assembled divides the screen, and even if one screen is formed with multiple screens, the screen is divided by the core region on a human perspective. do.

As a result, there is a problem that the core region acts as a decisive factor in making the screen look natural by this phenomenon.

An object of the present invention is to minimize the appearance of the core region by refracting an image of a cell adjacent to the core region into the core region in a state where the plurality of plasma display panels are assembled.

In the multi-screen plasma display device according to the present invention, a plurality of plasma display panels are assembled into one, and a photorefraction member is installed on an upper portion of a core region formed in the assembled state, and the image is refracted by the upper portion of the core region. It is configured to reduce the appearance of the area.

The refractive member of the transparent material may be variously implemented, but the cross section may be formed by combining the first refraction portion and the second refraction portion, each of which has a trapezoidal or equilibrium shape. In addition, by changing the structure of the upper substrate constituting the panel can be configured to display the screen refractively above the core region.

Hereinafter, exemplary embodiments of a multi-screen plasma display device according to the present invention will be described in detail with reference to the accompanying drawings.

An embodiment according to the invention discloses an improved structure in the shim region of a panel assembled as in FIG. 1.

First, as shown in the first embodiment (FIG. 3) and the second embodiment (FIG. 4) above the shim region 30 between the adjacent panels, a screen displayed on the edge of the adjacent panel is formed by installing a light refractive member of transparent material. Refractive transmission through the seam region can minimize the appearance of the seam region.

That is, as in the first embodiment, the optical refraction member includes a first refraction portion 40 and a second refraction portion 42 each having a trapezoidal cross section, and the first refraction portion 40 and the second refraction portion One side of the 42 is adhered to each other, and the other side of the first refraction portion 40 and the second refraction portion 42 is adhered to the edge of the panel.

In this case, it is preferable that the widths of the side surfaces of the first refraction portion 40 and the second refraction portion 42 adhered to correspond to a region where at least one or more cells of the panel are displayed are determined.

Sides of the first refracting portion 40 and the second refracting portion 42 adhered to the panel form a bottom surface of the optical refraction member, and form a path through which the screen displayed on the panel is incident.

That is, the screen displayed on the panel is incident on the first refraction unit 40 and the second refraction unit 42, respectively, and the incident screen is refracted and is then refracted and transmitted upward.

In this case, the degree of refraction of the screen is determined by the interface characteristics and the inclination angle of the refraction unit 40, which is preferably determined to be determined as the optimal state according to the intention of the manufacturer.

In the present invention, as shown in the second embodiment, the first refraction unit 50 and the second refraction unit 52 may be formed as shown in FIG. 4.

Although the second embodiment has a different shape of the optical refraction member, the mechanism for refracting the screen to the upper portion of the core region of the first embodiment has the same effect.

That is, as shown in FIG. 4 according to the second embodiment, the optical refraction member has a first refraction portion 50 and a second refraction portion 52 each having a cross-sectional equilibrium shape and a first refraction portion ( 50 and one side of the upper surface of the second refractive portion 52 abut each other, and the bottom surface of the first refractive portion 50 and the second refractive portion 52 is bonded to the side of the panel, respectively.

Accordingly, the screen displayed on the panel is incident on the first refraction unit 50 and the second refraction unit 52, respectively, and the incident screen is refracted and then is refracted and transmitted upward.

In addition, a third embodiment according to the present invention may be configured as shown in FIG.

That is, a plurality of panels in which the upper substrate 60 and the lower substrate 62 are sealed by the sealing unit 64 are assembled to form a single screen, and the inclined surface 70 is disposed below the edge of the upper substrate 60 of the adjacent panels. ) Is formed. In addition, end portions of the upper substrates 60 of adjacent panels are in contact with each other, and the side shock absorbing members 66 for each panel are formed under the inclined surface 70.

Therefore, in the third embodiment, the screen adjacent to the seam region where the buffer member 66 is in contact is refracted through the inclined surface.

As a result, in the embodiments of the present invention as in the first to third embodiments, the screen of the panel adjacent to the core region is refracted and transmitted through the core region, thereby minimizing or preventing the core region from being exposed.

Therefore, according to the present invention, the screen is refracted and transmitted through the upper portion of the core region, thereby minimizing the display of the core region in a state where a plurality of panels are combined to form a single screen, so that the screen looks natural.
