Referring to fig. 1, fig. 1 is a schematic diagram of a display device 100 according to an embodiment of the invention. In one aspect, the present invention provides a display device 100, which includes a first panel 110 and a second panel 120, wherein the first panel 110 has an arc-shaped edge 112, the second panel 120 has an arc-shaped edge 122, the arc-shaped edges 112, 122 are disposed opposite to each other, and the first panel 110 and the second panel 120 are connected to each other by the arc-shaped edges 112, 122. The curved edges 112, 122 are shown as overlapping to represent a tight engagement of the first panel 110 and the second panel 120, but in practice there may be a slight gap between the curved edges 112, 122.

Referring to fig. 2, fig. 2 is an enlarged schematic view of a portion S2 of the display device 100 in fig. 1. The first panel 110 and the second panel 120 respectively include a plurality of pixels 114 and 124, and for convenience of description, only a portion of the pixels 114 and 124 are highlighted by a thick line, and the number of the pixels 114 and 124 should not be limited by the thick line. One portion of the pixels 114, 124 is adjacent to the curved edges 112, 122, and the other portion of the pixels 114, 124 is away from the curved edges 112, 122. The pixels 114, 124 adjacent the curved edges 112, 122 are not as full in shape (e.g., square in the figure) as the pixels 114, 124 distal from the curved edges 112, 122. The pixels 114, 124 adjacent to the curved edges 112, 122 have curved pixel edges 116, 126 near one end of the curved edges 112, 122, respectively, and these pixel edges 116, 126 are connected to each other to form the curved edges 112, 122.

In one or more embodiments of the present invention, the arc-shaped edges 112, 122 are periodic arc-shaped structures, and since the arc-shaped edges 112, 122 are disposed oppositely, the arc-shaped edges 112, 122 have the same period P. Here, although the arc-shaped edges 112 and 122 are arranged in a periodic arc-shaped structure, the period P is not necessarily an integral multiple of the period P.

In an ideal situation, the pixels 114, 124 that are away from the arc-shaped edges 112, 122 are the same size, and the pixels 114, 124 have a pixel width W1. The period P of the curved edges 112, 122 should be designed to be a prime multiple of the pixel width W1, such that the pixel width W1 and the period P have a larger least common multiple. For example, the period P may be designed to be equal to a prime number between 3 and 97 times the pixel width W1.

Taking the pixel size as 576 microns by 576 microns as an example, and the pixel width W1 as 576 microns, the period P of the curved edges 112, 122 can be designed to be equal to 4.032 mm, i.e., the period P is seven times the pixel width W1, as shown in the figure. Alternatively, the arcuate edges 112, 122 may be arranged to have a period P equal to 55.872 millimeters, i.e., the period P is ninety-seven times the pixel width W1.

The design period P is a prime multiple of the pixel width W1, and is mainly aimed at reducing the number of times the curved edges 112, 122 intersect with the pixels 114, 124, and reducing the number of periods of the curved edges 112, 122, so as to reduce the intensity of the high-frequency edge signals of the display device 100.

Although the pixels 114 of the first panel 110 and the pixels 124 of the second panel 120 are designed to be the same size, the invention is not limited thereto, and the pixels 114 of the first panel 110 and the pixels 124 of the second panel 120 may be different sizes, but it should be noted that the period P is preferably designed to be still a prime multiple of the width of the pixels 114 or the pixels 124.

Because the arcuate edges 112, 122 are oppositely disposed, the arcuate edges 112, 122 have the same amplitude a in addition to the same period P. For convenience of description, a center line C is defined between the first panel 110 and the second panel 120, and a distance from any point on the center line C to the center of the first panel 110 is equal to that of the second panel 120. The amplitude a is the maximum distance from the arc-shaped edges 112, 122 to the center line C, and is preferably smaller than the pixel width W1 of the pixels 114, 124.

In one or more embodiments of the present invention, each pixel 114, 124 includes a plurality of sub-pixels 118, 128, and the sub-pixels 118, 128 have a sub-pixel width W2. In the present embodiment, the pixels 114 and 124 are respectively composed of three sub-pixels 118 and 128 in a side-by-side manner, such that the pixel widths W1 of the pixels 114 and 124 are three times the sub-pixel widths W2 of the sub-pixels 118 and 128, respectively. As described above, since the set pixel 114 and the pixel 124 are the same size, the sub-pixel 118 and the sub-pixel 128 are the same size. For the convenience of manufacturing and effective achievement of the visual marginlessness of the tiled panel, the amplitude a should be designed to be between the sub-pixel width W2 and the pixel width W1.

For example, taking the pixel size as 576 microns by 576 microns as an example, the pixel width W1 of the pixels 114, 124 is 576 microns, and the sub-pixel width W2 of the sub-pixels 118, 128 is 192 microns, and the arc edges 112, 122 are designed such that the amplitude a is between 192 microns and 576 microns.

In the present embodiment, the first panel 110 and the second panel 120 are configured in the same manner, for example, the pixels 114 and 124 and the sub-pixels 118 and 128 are configured in the same manner, but this is not intended to limit the present invention, and although not shown in the embodiments, the configurations of the first panel 110 and the second panel 120 may be different, that is, the first panel 110 and the second panel 120 may have different resolutions.

Referring to fig. 3, fig. 3 is a schematic diagram of a display device 200 according to another embodiment of the invention. Another aspect of the present invention provides a display device 200, wherein the display device 200 is a large-scale display, the display device 200 includes a plurality of panels 210, the panels 210 are arranged in an array, each of the panels 210 has a plurality of arc-shaped edges 220 along a first direction D1, the arc-shaped edges 220 of any two adjacent panels 210 are disposed opposite to each other, such that any two adjacent panels 210 are connected to each other by the arc-shaped edges 220. In the embodiment, the number of panels 210 and the number of cycles of the arc-shaped edge 220 are only used as examples, and the scope of the invention should not be limited by the number of panels 210 and the number of cycles of the arc-shaped edge 220 in the figure.

In one or more embodiments of the present invention, the panels 210 also have a plurality of curved edges 230 in the second direction D2, wherein the first direction D1 is perpendicular to the second direction D2, and the curved edges 230 of any two adjacent panels 210 are disposed opposite to each other, such that any two adjacent panels 210 can be connected to each other by the curved edges 230.

Referring to fig. 4, fig. 4 is an enlarged schematic view of a portion S4 of the display device 200 in fig. 3. The panel 210 includes a plurality of pixels 212, and for convenience of illustration, only a portion of the pixels 212 are highlighted by a thick line, and the number of the pixels 212 is not limited by the thick line. Here, a portion of the pixels 212 are adjacent to the arc-shaped edges 220, 230, and another portion of the pixels 212 are away from the arc-shaped edges 220, 230. Pixels 212 adjacent to the arc edges 220, 230, not as far away from the arc edges 220, 230, have a full pixel shape. The pixels 212 adjacent to the arc-shaped edges 220, 230 have differently shaped arc-shaped pixel edges 214 near one end of the arc-shaped edges 220, 230, and the pixel edges 214 of the pixels 212 are connected to each other to form the arc-shaped edges 220, 230.

In one or more embodiments of the present invention, the arc-shaped edges 220, 230 are periodic arc-shaped structures, the arc-shaped edge 220 in the first direction D1 has a first period P1, and the arc-shaped edge 230 in the second direction D2 has a second period P2. The first period P1 may be equal to or not equal to the second period P2. In the present embodiment, for example, the first period P1 is set equal to the second period P2.

In one or more embodiments of the present invention, the pixel 212 has a pixel width W1, and the first period P1 and the second period P2 are prime multiples of the pixel width W1 of the pixel 212, respectively, such that the pixel width W1 has a larger least common multiple than the first period P1 or the second period P2. As mentioned above, the main purpose of this configuration is to reduce the number of cycles of the curved edges 220, 230 and reduce the number of intersections between the curved edges 220, 230 and the pixels 212, so as to reduce the intensity of the high frequency signals at the edges of the display device 200. For example, the first period P1 or the second period P2 may be designed to be equal to a prime number between 3 and 97 times the pixel width W1.

Referring back to fig. 4, in one or more embodiments of the present invention, the arc-shaped edges 220 respectively have a plurality of amplitudes a 1. Any two panels 210 adjacent to the curved edge 220 have a center line C1, the center line C1 extends in the first direction D1, and the amplitude a1 is the maximum distance from the curved edge 220 to the corresponding center line C1, and is designed such that the amplitude a1 is smaller than the pixel width W1. Similarly, the arc-shaped edges 230 also have a plurality of amplitudes a2, and any two panels 210 adjacent to the arc-shaped edges 230 have a center line C2, the center line C2 extends toward the second direction D2, the amplitude a2 is the maximum distance from the arc-shaped edge 230 to the corresponding center line C2, and the amplitude a2 should be smaller than the pixel width W1.

Here, since the pixel 212 can be subdivided into a plurality of sub-pixels 216, and the sub-pixels 216 have a sub-pixel width W2, for convenience of manufacturing, the arc-shaped edge 220 is designed such that the amplitude a1 or the amplitude a2 is between the sub-pixel width W2 and the pixel width W1. For example, in the present embodiment, the amplitude a1 and the amplitude a2 are designed to be equal to approximately twice the subpixel width W2 of the subpixel 216. Although the amplitude a1 is equal to the amplitude a2 in the embodiment, the amplitude a1 may be designed to be different from the amplitude a2 according to practical requirements, so that the edge hf signal intensities of the panel 210 in the first direction D1 are different from those in the second direction D2.

The invention provides a display device, which is formed by connecting a plurality of display panels to form a large-scale display device, and the display panels are designed to have arc-shaped edges, so that the problem that the edges of straight line shapes easily cause constructive interference and panel joints are brighter can be solved, a user is not easy to perceive joint gaps of the display panels, and the image quality is improved.

Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention.
