Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an organic light emitting display panel 100 according to an embodiment of the present invention includes a plurality of effective display regions 110 and a plurality of bending circuit regions 120.
The effective display Area 110 (i.e., AA Area, active Area) is an Area of the organic light emitting display panel 100 where an image is displayed. That is, the pixel points (not shown) are distributed within the effective display area 110.
In the present embodiment, the number of the effective display areas 110 is 6, and the effective display areas are separated from each other. That is, no pixel point is disposed in the portion between the effective display regions 110.
The lead wires for lighting the pixel points in the effective display area 110 are distributed in the bent circuit area 120, and the pixel points are controlled to emit light by giving different electric signals to the lead wires, so that the effective display area 110 is controlled to display different images.
In the organic light emitting display panel 100 of the present invention, the bending circuit area 120 is connected between two adjacent effective display areas 110, that is, the bending circuit area 120 also has a function of isolating two adjacent effective display areas 110. In addition, the portion of the bent line region 120 is flexible and can be bent. This can change the angle of the dihedral angle between two adjacent effective display areas 110.
In the present embodiment, the number of the bending line regions 120 is 5.
Since the bent line region 120 may be bent, the organic light emitting display panel 100 can be folded into a polyhedral shape by bending the bent line region 120 from a flat state. In the folded polyhedron, each effective display area 110 is located on a face of the polyhedron, that is, each effective display area 110 constitutes a face of the polyhedron; meanwhile, each of the bending line regions 120 is a polyhedron, that is, each of the bending line regions 120 constitutes an edge of a polyhedron.
In the present embodiment, the polyhedron into which the organic light emitting display panel 100 is folded is a rectangular parallelepiped. Correspondingly, the 6 effective display areas 110 are all rectangular, and the 5 bending connection areas 120 are also rectangular.
In the present embodiment, the width of the bending line region 120 is 1 to 5 mm. This facilitates the bending of the bending circuit area 120 and effectively increases the area of the effective display area 110.
For convenience of description, the 6 effective display areas 110 are respectively numbered as an effective display area 111, an effective display area 112, an effective display area 113, an effective display area 114, an effective display area 115, and an effective display area 116.
In the present embodiment, the distribution of the effective display area 110 and the bending connection area 120 is as shown in fig. 1. The method specifically comprises the following steps: the front effective display area 114 and the rear effective display area 112 are connected to the upper effective display area 111 by a bent connection area 120. Of course, it is understood that the present invention is not limited to the above-mentioned forms, and may be in other distribution forms that can be folded into a rectangular parallelepiped, for example, the front left, back right effective display areas are sequentially connected by the bending connection area, the top effective display area is connected to the left effective display area by the bending connection area, and the bottom effective display area is connected to the back effective display area by the bending connection area.
In the present embodiment, the other effective display regions 110 are transparent display regions except the effective display region 116 located on the bottom surface of the polyhedron. The human eye can see the products behind the transparent display area through the transparent display area and can also see the images (including graphics, characters and the like) displayed on the transparent display area. For example, when the product is displayed, the product is placed behind the transparent display area, so that the product can be seen by human eyes, and meanwhile, the introduction about the product can be seen on the transparent display area.
Of course, it is understood that different effective display areas 110 may be selected as the transparent display areas according to different actual requirements, or different numbers of effective display areas 110 may be selected as the transparent display areas. For example, the active display areas of the bottom and back surfaces are non-transparent, and the other active display areas are transparent; for another example, only the front active display area is transparent, while the other active display areas are non-transparent. Of course, it is also understood that the active display area 110 of the present invention may be non-transparent.
Of course, it can be understood that each effective display area 110, i.e. each face of the polyhedron, can display the same image or different images according to the requirements of the actual situation. For example, when the product is displayed, each effective display area correspondingly displays the view of the direction of the product and the product introduction content.
Generally, the organic light emitting display panel 100 further includes a bonding area 140, and the main function of the bonding area 140 is to bond the organic light emitting display panel 100 to an FPC (not shown) so as to obtain signal control. In this embodiment, the number of the bonding areas 140 is one, and the bonding area 140 is connected to the active display area 110 through the bonding area 130. That is, the bonding area 130 is connected between the bonding area 140 and an active display area 110.
In this embodiment, bonding area 130 is also flexible and can be bent. This may change the angle of the dihedral angle between the bonding area and the active display area 116 connected thereto.
Of course, it is understood that the polyhedron of the present invention is not limited to a rectangular parallelepiped, but may be other polyhedrons such as a regular tetrahedron, a regular octahedron, a truncated pyramid, and the like. Correspondingly, the shape of the effective display area is not limited to a square, and can also be a diamond, a trapezoid, a triangle, and the like. The shapes of the respective effective display areas may be the same or different.
Referring to fig. 2, fig. 2 is a diagram illustrating an organic light emitting display 200 according to another embodiment of the present invention.
