Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It is to be understood that equivalents and modifications are possible.

2 is a view for explaining a configuration of a large area display device using a tilted display according to the first embodiment of the present invention.

2, a large area display device using a tilted display according to the present invention includes a panel 100 in which a plurality of displays 110 are arranged in a plane, a screen 100 disposed in a predetermined distance from the front surface of the panel 100, And a plurality of lenses 300 arranged between the panel 100 and the screen 200 and projecting an image applied from the panel 100 onto the screen 200 .

In the display panel 100, a plurality of displays 110 are arranged in a plane, and the bezel is overlapped with the adjacent display 110.

3, the display 110 includes a screen portion 111 for displaying and outputting an image, and a bezel portion 112 including an outer frame region of the screen portion 111. [

At this time, the bezel areas corresponding to the same axis are overlapped with each other so that the display 110 is tilted in one direction. FIG. 3 shows a configuration in which a bezel area formed in one direction, that is, an X-axis direction, is superimposed on the display 110. In FIG. 3, the first display 110a and the second display 110b disposed adjacent to the first display 110a overlap the bezel portion formed in the X-axis direction.

In addition, the bezel portion disposed on the lower side and the bezel portion disposed on the upper side are tilted so as to have the same inclination angle in one direction with respect to the overlapping target bezel portions on both sides of the displays. 3, the right superimposed bezel portion of the first display 110a is disposed above the superimposed bezel portion of the adjacent second display 110b, and the upper superimposed bezel portion of the first display 110a is disposed below the adjacent display Shape.

At this time, wirings such as FFC (Flexible Flat Cable) for driving the display are arranged on the lower side of the adjacent display in which the bezel part is superimposed. 3 illustrates a configuration in which the wiring F of the second display 110b is disposed on the lower side of the first display 110a which is superimposed on the left side.

The non-display area due to the bezel 112 of the display 110 constituting the display panel 100 is reduced and the wiring such as a flexible flat cable (FFC) , It is possible to reduce the resolution loss due to this.

On the other hand, the lens 300 rotates the light projected from the panel 100 by 180 degrees and enlarges the image on the screen 200 at a predetermined ratio. Accordingly, the panel 100 displays and outputs a 180 ° rotated image corresponding thereto.

The lens 300 includes at least one lens 300 corresponding to each of the displays 110 constituting the display panel 100. The number of lenses 300 disposed in one display 110 may be appropriately set in consideration of the distance between the display 110 and the screen 200 according to the optical characteristics of the lens 300. For example, the display 110 may be configured as a cellular phone and eight lenses arranged in a 2 x 8 structure (X axis x Y axis) may be arranged.

In addition, the lens 300 enlarges an image provided from a corresponding region of the display 110 at a predetermined ratio and projects the image on the screen 200. That is, the position of the lens 300 is set so that the image of one display 110 is enlarged by the bezel size and projected on the screen 200. [ At this time, the position of the lens 300 is set to a position where the size of the enlarged area of the image enlarged with respect to the arrangement direction of the overlapping bellies of the display 110 is set to 1 / N (N is the number of lenses) Respectively. For example, in FIG. 4, when two lenses are arranged in the arrangement direction of the overlapping bevel portion of the display 110, the sizes of the image enlargement regions of the first and second lenses 310 and 320 are respectively 1 / 2 (D / 2).

As shown in FIG. 3, a plurality of displays 110 are arranged in a plane so as to overlap the bezel portions 112, so that one of the bezel regions to be superposed on both sides of the display 100 is positioned on the lower side and the other side is arranged on the upper side The display 100 is arranged in a slanting manner so as to have a predetermined slope.

In this case, the direction of light projected toward the screen 200 through the lens 300 changes according to the oblique arrangement of the display 110, and the light from the display 110 passes through the lens 300 to the screen 200 The resolution of the image displayed and outputted through the screen 200 may be lowered due to the change of the focus of the light to be formed.

In consideration of this, in the present invention, each lens focuses entirely on the image projected from the display 110 to the screen 200 in a state in which the arrangement position is set between the panel 100 and the screen 200 corresponding to the focal distance And is configured to newly set the inclination axis to be aligned, and thus to position the lens 300. [

That is, when the display 110 is disposed at an angle to the screen 200 at an angle as shown in FIG. 5, the display arrangement line extension line 110L and the lens arrangement line extension line (not shown) according to the scheimpflug theory (Lens array line extension line 300L) is set so as to satisfy the intersection of the screen layout line extension lines 300L and 300L, that is, the scan plug intersection SI.

Also, in the present invention, when a plurality of lenses 300 are disposed for one display 110, the lens 300 may be arranged to have the same inclination axis for at least two lenses in the same axial direction.

5A, the display arrangement line extension line 110L is inclined with respect to the screen arrangement line extension line 200L and the first and second lenses 110R, (B) is a graph in which the lens arrangement line extension line 300L for the first and second lenses 310 and 320 is taken as the X axis in a state where the lenses 310 and 320 are arranged.

The distance u and v between the display arrangement line extension line 110L and the screen arrangement line extension line 200L with respect to the lens arrangement line extension line 300L is set to be t When solved by applying to the lens formula of Equation (1), a relational expression as shown in Equation (2) is derived.

Here, f is the focal length.

The distance between the lens 300 and the display 110 with respect to an arbitrary point t when the screen arrangement line extension line 200L is "y = ax" and the display arrangement line extension line 110 is "y = bx" quot; u = bt ", the distance between the lens 300 and the screen 200 is "v = at ". This is applied to Equation (1) to calculate Equation (2).

Here, since the display 110 is generally a flat display and its size (length or width) is small, the inclination [theta] of the display 110 with respect to the screen 200 when the bezel portion 112 is overlapped is approximately 1 To 2 [deg.].

Accordingly, in the present invention, the maximum inclination of the display is set to "2 DEG" to calculate "b = 0.0349 ", and" t " ), The distance between the display 110 and the screen 200 is calculated as "5605 to 5726 mm ". At this time, the inclination angle? Of the display 110 with respect to the screen 200 is calculated as "0.6875" and "0.6646". That is, it can be seen that the change of the angle is relatively small compared to a fairly large distance value between the screen 200 and the display 110. Here, the process of calculating the distance between the display 110 and the screen 200 according to the inclination and the inclination angle? Of the display 110 with respect to the screen 200 is performed by a known calculation process, and the detailed calculation formula thereof is omitted .

As a result, it can be seen that the first and second lenses 310 and 320 adjacent to one display 110 do not affect the resolution even if they are arranged to have the same inclination axis.

In the case where a plurality of lenses 300 are disposed on the upper side of the panel 100, the lenses 300 may invade the optical area of the adjacent other lens 300, Noise can be generated.

Accordingly, in the present invention, the lens 300 may be configured to form the barrier rib 400, as shown in FIG. 2, in order to project only the image of the region 300 to the screen.

6, the barrier rib 400 may have a barrel shape having a predetermined length, for example, a barrel shape corresponding to the outer rim of the lens 300. FIG. 6 shows a structure of a barrel 400 having a barrel shape corresponding to a lens array of a 2 × 4 structure for the display 110.

The end of the barrier rib 400 is spaced apart from the screen 100 by a predetermined distance. This is to prevent the partition wall 400 from being visually recognized through the screen 100, and also to cause the image projected through the lens 300 to be projected on the entire screen. That is, the distance between the barrier ribs 400 and the screen 100 can be properly set to a distance at which a desired enlarged image is projected on the entire screen without causing image noise between adjacent lenses 300.

Meanwhile, in the present invention, the slit member 500 may be provided to reduce the distortion caused by the curvature of the lens.

7, the slit member 500 includes a support plate 510 and a slit 520 formed to correspond to the center point of the lens 300. 7 shows a slit member 500 corresponding to a 2x4 lens array for the display 110. In FIG. The slit member 500 is disposed adjacent to the lens 300 and is disposed between the display 110 and the lens 300, that is, below the lens 300, or between the lens 300 and the screen 200 , That is, on the upper side of the lens 300. Further, the slit member 500 may be provided on both the upper side and the lower side of the lens 300. FIG. 1 shows a structure in which a slit member 500 is disposed on the lower side of the lens 300.

That is, according to the embodiment, the bezel portions of the display are overlapped to form the panel, and the lens is inclined corresponding to the tilting between the screen and the panel, thereby improving the resolution per area.
