Detailed Description
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a schematic view of an alternative embodiment of a display panel according to an embodiment of the present invention, and fig. 2 is a schematic view of the display panel in fig. 1 when a foldable portion is in a folded state. Fig. 3 is a schematic cross-sectional view at the position of the tangent line Q1 in fig. 2.
As shown in fig. 1, the display panel includes a foldable portion T, and the foldable portion T is bent toward a side away from the display surface of the display panel to form a notch K (see fig. 2). As shown in fig. 3, fig. 3 is a schematic cross-sectional view of the display panel when the foldable portion T is in a folded state, and the foldable portion T is located on a side of the display surface M away from the display panel after being folded. The display surface M is a surface of the display panel displaying a picture. When the display device is assembled, a camera, an inductor and other devices can be arranged at the position of the notch K.
With continued reference to fig. 1 and 2, the display panel further includes a display area AA, the display area AA includes a first display area AA1 located at two sides of the notch K in the first direction a, and the first display area AA1 includes a plurality of scan lines G extending along the first direction a; wherein, a VT test circuit S1 is arranged on the foldable part T; shift registers VSR are also provided in the foldable portion T, and one shift register VSR is electrically connected to at least one scanning line G. It is understood that a plurality of scan lines, not shown in fig. 1, are also included in other display areas of the display panel. In a conventional display panel, shift registers for driving scan lines are generally disposed in left and right borders of the display panel (i.e., in the non-display area BA1 in fig. 1). The central idea of the invention is to arrange at least part of the shift registers driving the scanning lines in the first display areas on both sides of the aperture in the foldable part.
It should be noted that the arrangement positions and the number of the shift registers VSR and VT test circuits S1 in fig. 1 are only schematic representations, and the number and the positions can be designed according to specific requirements in practice. One shift register VSR may be electrically connected to one scan line G, or one shift register VSR may be electrically connected to two scan lines G. The sizes of various parameters of the two first display areas positioned at the two sides of the notch in the display panel provided by the invention can be the same or different.
In the present invention, the driving method of the scan line in the first display region is not limited. The scan lines in the first display area may be driven by a single-side driving method (as shown in fig. 1), or two scan lines in two first display areas may be driven simultaneously by the same shift register disposed in the foldable portion. The number of shift registers can be reduced in the left and right borders of the display panel, i.e., the non-display area BA1 in fig. 1, so that the space of the non-display area is saved, and the borders are narrowed. In addition, in the conventional display panel, the VT test circuit is disposed at a lower frame position of the display panel, i.e., in the non-display area BA2 in fig. 1, while the present invention disposes the VT test circuit S1 at the foldable portion T and then bends to the back of the display panel along with the foldable portion T, so that the space of the non-display area BA2 can be saved, which is beneficial to narrowing the non-display area BA 2. A common voltage line, an electrostatic discharge circuit, and the like may also be provided in the foldable portion.
The display panel provided by the invention is provided with the foldable part which can be bent towards the side of the display surface away from the display panel, and the VT test circuit and part of the shift register are arranged in the foldable part, so that the space of a non-display area can be saved, and the narrowing of a frame is facilitated, and the screen occupation ratio is improved.
In one embodiment, the display panel may also include two foldable portions. Fig. 4 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present invention. Fig. 5 is a schematic view of the display panel provided in fig. 4 when the foldable portion is in a folded state. As shown in fig. 4, the display panel includes two foldable portions T, and the display panel forms an inverted triangular notch K (see fig. 5) after the two foldable portions T are simultaneously folded. With continued reference to fig. 4 and 5, the display panel further includes a display area AA, the display area AA includes a first display area AA1 located at two sides of the notch K in the first direction a, and the first display area AA1 includes a plurality of scan lines G extending along the first direction a; wherein, a VT test circuit S1 is arranged on the foldable part T; shift registers VSR are also provided in the foldable portion T, and one shift register VSR is electrically connected to at least one scanning line G. When the display device is assembled, a camera, an inductor and other devices can be arranged at the position of the notch K. The arrangement positions and the arrangement number of the shift registers VSR and VT test circuits S1 in fig. 4 are only schematically shown. The display panel provided by the embodiment is provided with two foldable parts which can be bent towards one side of the display surface deviating from the display panel, and the VT test circuit and part of the shift register are arranged in the foldable parts, so that the space of a non-display area can be saved, and the narrowing of a frame is facilitated, and the screen occupation ratio is improved.
In the display panel provided by the invention, the foldable part comprises a bending shaft, the length of the bending shaft in the extending direction of the bending shaft is d1, the notch is provided with a first edge extending in the extending direction of the bending shaft, and the length of the first edge is d2, wherein d1< d 2.
In one embodiment, the direction of extension of the bending axis is the same as the first direction. Taking the display panel illustrated in fig. 1 as an example, fig. 6 is a schematic cutting diagram of a display panel according to an alternative embodiment of the present invention during manufacturing. Fig. 7 is a schematic diagram illustrating a display panel cut in the related art. When the display panel is manufactured, the entire panel may be cut to form the foldable portion T, as shown in fig. 6, the display panel may be cut along cutting lines X, each of the two cutting lines X has a cutting cut-off point D along the first direction a, a portion between the two cutting cut-off points D forms a bending axis Z of the foldable portion T, a distance between the two cutting cut-off points D along the first direction a is a length D1 of the bending axis Z, and after the foldable portion T is bent, a distance between the two cutting lines X in the first direction a is a length D2 of a first edge (in combination with the first edge F illustrated in fig. 2) of the notch K extending in the first direction a (i.e., in an extending direction of the bending axis Z), and D1< D2. As shown in fig. 7, in the related art, the cut point of the display panel cutting line X ' is D ', and when the foldable portion T ' is bent along the bending axis Z ', the bending stress is concentrated on the corner region Y ', which may cause the tearing fracture in the region. According to the invention, the cutting line X is designed to have a corner (see the area Y in fig. 6), so that the area Y can be protected (namely the corner position of the notch is protected) when the foldable part T is bent, and the phenomenon that the bending stress is concentrated at the corner position to cause the fracture of the corner can be avoided, thereby avoiding the fracture of the routing and improving the reliability of the display performance.
In one embodiment, the direction of extension of the bending axis intersects the first direction. Taking the display panel illustrated in fig. 4 as an example, fig. 8 is a schematic view of a display panel according to another alternative embodiment provided in an embodiment of the present invention. As shown in fig. 8, the foldable part T includes a bending axis Z, and the length of the bending axis Z in the extending direction c of the bending axis Z is d1, and the notch K has a first edge (in combination with the first edge F illustrated in fig. 5) extending in the extending direction c of the bending axis Z, and the length of the first edge is d2, wherein d1< d 2. In the manufacturing process of the display panel provided by the embodiment, firstly, the cutting is performed along the straight line where the tangent line X3 is located, and then, a part is cut inwards along the direction c to form two mushroom-like foldable portions T, so as to reduce the length of the bending axis Z and facilitate the bending of the foldable portions T towards the back.
In an embodiment, fig. 9 is a schematic cut-away view of a display panel according to another alternative implementation manner provided by an embodiment of the present invention during manufacturing. As shown in fig. 9, a through hole W is provided in a bending region where the bending axis Z is located, and the through hole W penetrates the foldable portion T in a direction perpendicular to the display panel when the foldable portion T is in the unfolded state. In practice, under the condition that the routing setting is ensured to be satisfied, the length of the through hole W along the direction c can be sufficiently long, and in this embodiment, the length of the bending shaft can be further reduced, the control force applied to the foldable portion to help the foldable portion to bend can be reduced, the external force borne by the foldable portion is correspondingly reduced, and the foldable portion can be better bent to the back of the display panel. In an embodiment, fig. 10 is a partial schematic view of a display panel according to an embodiment of the invention.
