Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a flexible display panel according to an embodiment of the present invention, and referring to fig. 1, the flexible display panel includes a display area 100 and a telescopic transition area 200, and under the same stress, a deformation of the telescopic transition area 200 is greater than a deformation of the display area 100; the display area 100 includes a central display area 110 and at least one annular display area 120, the at least one annular display area 120 surrounding the central display area 110; the telescopic transition region 200 includes at least one annular telescopic region 210, the at least one annular telescopic region 210 surrounds the central display region 110 and is concentric with the central display region 110, in the radial direction of the central display region 110, adjacent central display regions 110 and annular display regions 120 are connected by one annular telescopic region 210, and two adjacent annular display regions 120 are connected by one annular telescopic region 210.
The flexible display panel can be used for manufacturing a display device with a stereoscopic or other structure, and has a certain deformation capability, that is, the form of the flexible display panel can be properly adjusted by applying an external force during the manufacturing process of the display device. Illustratively, the flexible display panel shown in fig. 1 has a circular shape, and when a spherical stereoscopic display device is manufactured, the display panel may be stretched to form a spherical surface by protruding a central region. The structure that adopts display area 100 and flexible transition area 200 is set up, can utilize the stronger deformability of flexible transition area 200 to alleviate the atress of display area 100 to avoid the display area 100 atress to concentrate and produce the damage. Specifically, the flexible display panel adopts the annular display area and the annular flexible area with sequentially increased sizes to realize splicing with the central display area, and the adjacent annular display areas 120 are connected through the annular flexible area 210, so that the better flexible capacity of the annular flexible area 210 can be utilized, the tensile force generated in the stretching process is more concentrated in the annular flexible area 210, and the tensile force borne by the annular display area 120 is reduced.
It should be noted that the shape of each annular display area 120 and each annular transition area 210 can be adaptively set according to the shape of the central display area 110. Generally, as shown in the figure, when the central display area 110 is circular, the shapes of the annular display area 120 and the annular transition area 210 also need to be circular, so that the edge where the annular display area 120 and the annular transition area 210 are connected can be uniformly stressed, and the display is prevented from being damaged due to concentrated local stress. Of course, the central display area 110, the annular display area 120 and the annular transition area 210 may be configured as a polygon with rounded corners, etc., and the shape thereof is not limited herein, and those skilled in the art can select and design the display device according to the structure of the actual display device.
According to the flexible display panel provided by the embodiment of the invention, the display area and the telescopic transition area are arranged, under the same stress, the deformation of the telescopic transition area is larger than that of the display area, the display area comprises the central display area and at least one annular display area, the telescopic transition area comprises at least one annular telescopic area, the at least one annular telescopic area surrounds the central display area and is concentric with the central display area, and in the radial direction of the central display area, the adjacent annular display area and the two adjacent annular display areas are connected through the annular telescopic areas, so that the flexible display panel is spliced into a whole. The flexible display panel provided by the embodiment of the invention solves the problem that the existing display panel is easy to break or fracture under stress when being prepared into a three-dimensional display device, realizes stress buffering of a display area, can avoid damage of different positions of the display panel due to stress, is beneficial to preparation of the three-dimensional display device and improves the yield of the three-dimensional display device.
As in the foregoing embodiment, the outermost region of the flexible display panel is set as the annular display region, which is only one embodiment of the present invention, and in another embodiment, the outermost region of the flexible display panel may be set as the annular expansion region, so as to avoid the damage of the display region in the edge region due to a large force during the stretching process. Fig. 2 is a schematic structural diagram of another flexible display panel according to an embodiment of the present invention, and referring to fig. 2, unlike the flexible display panel shown in fig. 1, an annular expansion region 210 is further connected to an outer side of the outermost annular display region 120 in a radial direction of the central display region 110.
When the annular telescopic area 210 is arranged at the outermost edge of the flexible display panel, the flexible display panel can provide large deformation in the outermost area, and the flexible display panel is guaranteed to complete the preparation of three-dimensional display structures such as a spherical surface. For the flexible display panel shown in fig. 1, the non-display frame of the display panel can be ensured to be narrower, thereby increasing the screen occupation ratio of the display device.
Because in the radial direction of central display area, annular display area and annular flexible district set up in turn, and its deformability has been decided to a certain extent to the width in annular flexible district, also can influence the area proportion of display area in the whole flexible display panel simultaneously. When the annular telescopic area is arranged, the deformation capacity and the area of the annular telescopic area need to be considered. With continued reference to fig. 1 and fig. 2, on the basis of the flexible display panel provided in the above embodiment, the widths of the annular expansion areas 210 in the radial direction of the central display area may be set to be the same. The same width of each annular expansion region 210 can ensure the consistent interval between the annular display regions 120, avoid the overlong or undersize interval between the annular display regions 120, and ensure the uniformity and continuity of the picture when displaying the picture.
It should be noted that the same width of each annular expansion region 210 in the radial direction means that each annular expansion region 210 has the same deformation capability. In comparison, the edge area of the flexible display panel is stressed more than the middle area in the stretching process, so that in order to meet the stretching requirements of different positions, the width of the annular telescopic area 210 needs to be set to at least meet the stretching requirements of the edge area, and at the moment, the annular telescopic area 210 at each position can meet the stretching requirements, so that the display areas at each position can be protected, and the flexible display panel can be guaranteed to be manufactured into a spherical and other three-dimensional display structure.
Fig. 3 and 4 are schematic structural diagrams of two flexible display panels provided by an embodiment of the present invention, and referring to fig. 3 and 4, in the flexible display panel, the widths of the annular expansion areas 210 increase sequentially in a radial direction of the central display area 110. The increasing width of each annular expansion region 210 means that the deformation capacity of each annular expansion region 210 increases. By reasonably setting the width of each annular telescopic zone 210, each annular telescopic zone 210 can meet the stretching requirement at the position. Moreover, the narrow annular telescopic region 210 is correspondingly arranged in the middle region with smaller stretching requirement in the stretching preparation process, and the occupation ratio of the telescopic transition region in the flexible display panel can be reduced, so that the occupation ratio of the display region is improved, the area of the display region is increased, and the display effect of the flexible display panel is improved.
As can be seen from the flexible display panels shown in fig. 1 and 2, compared with the flexible display panel shown in fig. 3, the flexible display panel shown in fig. 4 is different only in that the outermost side of the flexible display panel is the annular stretching region 210, and the outermost side of the flexible display panel shown in fig. 3 is the annular display region 120.
The deformability of the annular telescopic area can be made of a material with a flexible characteristic, and can also be realized by combining a structure capable of deforming. The following embodiments of the present invention will describe the annular expansion region in combination with a specific structure capable of deforming. Fig. 5 is a partially enlarged schematic view of the flexible display panel in fig. 1, referring to fig. 5, wherein the flexible display panel 210 includes a plurality of islands 11, a plurality of connecting bridges 12, and a plurality of openings 13; the connection bridge 12 is used to connect adjacent islands 11 or to connect the islands 11 with the display area 100; under the connection of the connecting bridges 12, the connecting bridges 12 and the islands 11 form a plurality of openings 13; the opening 13 is respectively adjacent to the connecting bridge 12 and the island 11 and is positioned between the adjacent connecting bridge 12 and the adjacent island 11; when the telescopic transition area 200 is stressed, the connecting bridge 12 and the opening 13 deform, so that the telescopic transition area 200 is telescopic.
Wherein, flexible transition zone 210 can stretch out and draw back the deformation, mainly depends on the hollow out construction that island 11 and connecting bridge 12 formed, under the connection of connecting bridge 12 promptly, a plurality of trompil 13 structures that form. The hollowed-out opening 13 formed by the interconnection of the island 11 and the connecting bridge 12 can deform to a certain extent when stressed, so that the whole telescopic transition area 210 deforms in a telescopic manner. Certainly, the island 11 and the connecting bridge 12 may be made of flexible or elastic materials, and when the telescopic transition region 210 is stressed, the island 11 and the connecting bridge 12 also deform to some extent, and the deformation of the opening 13 is matched to realize the integral stretching. It should be noted that the island 11 may be understood as a node where the connecting bridges 12 are connected to each other, and may have a certain area or a smaller area. The size of the area of the island 11 depends on the one hand on the shape and size of the connecting bridges 12 and on the number of connecting bridges 12 connected to the same island 11.
When the whole flexible display panel is manufactured into a spherical and other three-dimensional display device, stretching is realized mainly by means of deformation of the telescopic transition area 210, and certain stretching deformation capacity can be set for the display area. Therefore, the display area of the flexible display panel provided by the embodiment of the invention can also be formed by a hollow structure adopting a telescopic transition area. Fig. 6 is a partially enlarged schematic view of the display area of the flexible display panel shown in fig. 1, and referring to fig. 1, 5 and 6, the display area 100 is provided with a plurality of pixel units 10, the display area 100 and the telescopic transition area 200 are provided with a plurality of signal traces 20, and the signal traces 20 provide display driving signals to the pixel units 10;
the display area 100 includes a plurality of islands 11, a plurality of connecting bridges 12 and a plurality of openings 13, the pixel units 10 are disposed on the islands 11, and the signal traces 20 are disposed on the connecting bridges 12; the connection bridge 12 is used to connect adjacent islands 11 or to connect the islands 11 with the display area 100; under the connection of the connecting bridges 12, the connecting bridges 12 and the islands 11 form a plurality of openings 13; the opening 13 is respectively adjacent to the connecting bridge 12 and the island 11 and is positioned between the adjacent connecting bridge 12 and the adjacent island 11; when the display area 100 is stressed, the connecting bridges 12 and the openings 13 are deformed, so that the display area 100 is stretched.
The central display area 110 and the annular display area 120 of the display area 100 are all of the structure of the island 11, the connecting bridge 12 and the opening 13, the display area 100 can be buffered when stressed by utilizing the deformation of the opening 13, and meanwhile, certain deformation capacity can help the flexible display panel to stretch, so that the display area is prevented from breaking due to stress concentration. The pixel unit 10 and the signal wiring 20 are respectively arranged on the island 11 and the connecting bridge 12, so that the characteristic that the island 11 and the connecting bridge 12 are not deformed or have small deformation degree in the stretching process can be utilized, the damage such as breakage is avoided, and the normal work of a display area is ensured.
In the telescopic structure provided in the telescopic transition area 200 and the display area 100, the shape, size and density of the openings not only determine the deformation capability, but also affect the shape and size of the connecting bridge, thereby limiting the wiring of signal routing. In the flexible display panel provided in the embodiment of the present invention, the shapes of the openings of the flexible transition area 200 and the display area 100 may be at least one of a circle, an ellipse, a polygon, a cross, a flange, or a dumbbell. Since the islands 11 and the connecting bridges 12 in the telescopic transition area and the display area form the openings 13, the shapes of the islands 11 and the connecting bridges 12 are not regular circles and long strips in general, and the shapes of the islands 11 and the connecting bridges 12 are substantially complementary to the shape of the openings 13. Fig. 7-9 are partial enlarged views of three flexible display panel telescopic transition areas provided by the embodiment of the present invention, and referring to fig. 7-9, the opening 13 in the telescopic transition area can be configured as a quadrangle, a cross, and a dumbbell, for example. Obviously, when the openings 13 are irregular in shape, the corresponding islands 11 and connecting bridges 12 are also irregular in shape.
Further, considering that the main use for the telescopic deformation is the telescopic transition area 200, the deformation capability thereof should be larger than that of the display area, and generally, the material of the telescopic transition area 200 can be set to have better elastic capability. Of course, from the structural point of view, the shape-changing capability of the telescopic transition area and the display area can be changed by reasonably setting the shape, size, density and the like of the openings in the telescopic transition area and the display area. Comparing fig. 5 and fig. 6, on the basis of adopting the deformation structures of the islands and the connecting bridges in the flexible display panel provided in the above embodiment, the size of the opening 13 in the telescopic transition region 200 may be set to be larger than the size of the opening 13 in the display region 100. Fig. 10 is a partial enlarged view of another flexible display panel provided by an embodiment of the present invention, and referring to fig. 5 and 10, the density of the openings 13 in the telescopic transition region 200 may also be set to be greater than the density of the openings 13 in the display region 100. It can be understood that, in the hollow deformation structure, the larger the size of the opening 13 is, the higher the setting density is, and the larger the overall deformation capacity is. The open holes 13 with different sizes and/or different densities are respectively arranged in the telescopic transition area 200 and the display area 100, so that the telescopic effect of the display area 100 can be limited, and the deformation capacity of the telescopic transition area 200 can be enlarged, so that the flexible display panel can concentrate tensile stress on the telescopic transition area 200 when the three-dimensional display device is manufactured, and the display area is prevented from being damaged due to concentrated stress.
Further, the embodiment of the invention also provides a specific circuit layout design of the flexible display panel. Fig. 11 is a schematic structural diagram of another flexible display panel provided in an embodiment of the present invention, and referring to fig. 11, a plurality of pixel units 10 form a plurality of pixel unit rings 101 surrounding a central display area 110; the signal trace 20 includes a first signal trace 21 and a second signal trace 22; each first signal wire 21 is sequentially connected with a plurality of pixel units 10 in the same pixel unit ring 101, and the first signal wire 21 is located in the display area 100; each second signal trace 22 is sequentially connected to adjacent pixel units 10 in different pixel unit rings 101, the second signal trace 22 extends along the radial direction of the central display area 110, and the second signal trace 22 is located in the display area 100 and the telescopic transition area 200.
The first signal trace 21 is configured to provide a display driving signal to the plurality of pixel units 10 in the radial direction, and the second signal trace 21 is configured to provide a display driving signal to the plurality of pixel units 10 in the circumferential direction, so that the extending directions of the first signal trace 21 and the second signal trace 22 are the radial direction and the circumferential direction along the center of the flexible display panel, respectively. It should be noted that each ring-shaped display area 120 includes a ring of pixel units 101, which is only used to illustrate the distribution and routing of the first signal traces 21 and the second signal traces 22. In the actual flexible display panel annular display area 120, a plurality of pixel unit rings 101 may be provided to secure the number of pixel units 10, thereby securing the resolution of the annular display area 120. Moreover, in practice, the first signal trace 21 and the second signal trace 22 need to provide a plurality of driving signals to the pixel unit 10 through the driving chip, and therefore, the first signal trace 21 and the second signal trace 22 should be connected to the driving chip respectively, so that in the non-display area of the flexible display panel, the first signal trace 21 and the second signal trace 22 need to be reasonably wired and a connection structure needs to be set, so as to be bound and connected to the flexible circuit board or the driving chip.
In addition, because the connecting bridge in flexible transition district and the display area all need to have certain deformability, the signal that sets up on it walks the line and also avoids the deformation in-process to produce the scheduling problem of broken string. Therefore, the signal routing lines can be arranged to have certain bending resistance in the embodiment of the invention, namely, when the connecting bridge deforms, the signal routing lines on the connecting bridge can adaptively perform stress buffering. Alternatively, as can be seen from the partially enlarged views of the flexible display panel shown in fig. 5 to 10, the signal traces 20 may be disposed in a curved or folded shape. At this time, the curved or zigzag signal trace 20 can have a certain capability of reducing the risk of wire breakage when deformed, so that damage in the preparation process of the stereoscopic display device can be avoided, and the display function of the display panel is ensured.
An embodiment of the present invention further provides a display device, and fig. 12 is a schematic structural diagram of the display device provided in the embodiment of the present invention, and referring to fig. 12, the display device has the flexible display panel 1 provided in the above embodiment. The display device is made of the flexible display panel 1 provided by the above embodiment through stretching deformation, and the display device is made of the flexible display panel 1, so that the same beneficial effects as those of the flexible display panel provided by the above embodiment are achieved.
Further, referring to fig. 12, the display device further includes a spherical support structure 2, and the flexible display panel 1 is attached to a surface of the spherical support structure 2. The spherical support structure 2 itself has a spherical surface, and the flexible display panel 1 is attached to the spherical surface, so that the three-dimensional display of the spherical surface can be realized, that is, the display device is substantially a spherical three-dimensional display device. In particular, during the manufacturing process, a spherical support structure 2 and any one of the flexible display panels 1 provided in the above embodiments may be provided, where the flexible display panel 1 is a planar structure. The back of the flexible display panel 1 is abutted by the spherical supporting structure 2, the flexible display screen 1 is attached to the surface of the spherical supporting structure at the moment, and the flexible display panel is stretched into a spherical display panel at the moment.
