All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without making any inventive effort are intended to fall within the scope of the present invention.
Fig. 4 is a schematic plan view of a display panel according to an embodiment of the present invention, fig. 5 is a schematic cross-sectional view of the display panel according to an embodiment of the present invention, and fig. 6 is a schematic structural view of a touch functional layer of a region A3 in fig. 4. As shown in fig. 4, the display panel includes a display area 11b and a non-display area 11a disposed around the display area 11b, where the display area 11b includes a special-shaped display area A3, and then the entire display area 11b may be a special-shaped display area, or a part of the display area 11b may be a special-shaped display area A3, and the rest may be a display area with a conventional shape, and in this embodiment, the proportion of the special-shaped display area A3 to the display area 11b is not limited. The special-shaped display area A3 is an area with a nonlinear edge shape or an area with a corner being a non-right angle, and the edge of the special-shaped display area A3 is arc-shaped or the edge of the special-shaped display area A3 is provided with a notch.
The display panel includes a display functional layer 11 and a touch functional layer 12, where the touch functional layer 12 is disposed on the light emitting side of the display functional layer 11, in this embodiment, the display panel may be a liquid crystal display panel or an organic light emitting display panel, and if the display panel is a liquid crystal display panel, the display functional layer 11 is a film layer formed by bonding a backlight source, an array substrate and a color film substrate, and sub-pixels arranged in an array are formed on the film layer, and each sub-pixel can be controlled to display independently. If the display panel is an organic light-emitting display panel, the display function layer 11 includes an organic light-emitting material layer capable of self-light emission, an auxiliary light-emitting layer for assisting the organic light-emitting material layer to emit light, and the like. And the organic light emitting material layer includes a plurality of block structures such that the display function layer 11 forms a plurality of sub-pixels, the sub-pixels being located in a display region of the display function layer 11. In addition, referring to fig. 5, if the display panel is an organic light emitting display panel, the display functional layer 11 is disposed on the substrate 13, and a driving circuit layer is disposed on the substrate 13 for driving the display functional layer 11 to emit light, and optionally, because the organic light emitting material layer needs to isolate the water oxygen environment, a thin film packaging layer 14 is generally disposed on the light emitting side of the display functional layer 11, and the thin film packaging layer 14 is formed by alternately stacking organic materials and inorganic materials, so that the water oxygen element can be effectively isolated. In this embodiment, the touch functional layer 12 can be disposed with the thin film packaging layer 14 as a substrate, and no glass substrate is required to be disposed for the touch functional layer 12, so that the thickness of the entire display panel is reduced, and the light and thin arrangement of the display panel is facilitated.
With continued reference to fig. 4, the display area of the touch functional layer 12 includes a plurality of touch electrodes 124, the touch electrodes 124 are formed by metal grid wires 121, and the metal grid wires 121 are disposed in a gap area between adjacent sub-pixels, and referring to fig. 6, the front projection of the metal grid wires 121 on the display panel does not overlap with the sub-pixels 111, and does not shade the light emitted from the sub-pixels 111. The touch functional layer 12 includes a single metal grid trace 121, and adjacent touch electrodes 124 may be disconnected by a gap 125. In addition, the space 125 is also included in one touch electrode 124, so that the space is prevented from being only arranged between adjacent touch electrodes 124, and the space is uniformly distributed in the whole touch functional layer 12, so that the brightness of the display panel is uniform all over, and the problem of visible outline of the touch electrode 124 is avoided.
With continued reference to fig. 4 and 6, in the touch functional layer 12, the outer edge of the metal grid trace 121 is provided with a metal connection line 123 surrounding the metal grid trace 121, and since the edge of the special-shaped display area A3 is arc-shaped or non-linear, the metal connection line 123 is also not linear, in this embodiment, when the metal connection line 123 is formed, although the metal connection line 123 is not linear, the front projection of the metal connection line 123 on the display panel does not overlap with the front projection of the sub-pixel 111 at the edge of the special-shaped display area A3 on the display panel. The present embodiment avoids the problem that the non-linear metal connection line 123 easily covers the sub-pixel 111 disposed along the edge of the special-shaped display area A3, so that the open light-emitting area of the sub-pixel 111 is uncovered, and the display brightness of the display panel is enhanced. In addition, in the sub-pixels 111 arranged along the edge of the special-shaped display area A3, the situation that part of the sub-pixels 111 are shielded by the metal connecting lines 123 and part of the sub-pixels 111 are not shielded by the metal connecting lines 123 does not exist, so that the display brightness of the edge of the special-shaped display area A3 is uniform, and the display effect of the edge of the display panel is improved.
Based on the above embodiments, the edge of the shaped display area A3 may include at least one non-right angle and/or at least one notch. As shown in fig. 4, the case where the edge of the special-shaped display area A3 includes a non-right angle is shown in fig. 4, the special-shaped display area A3 may include one or more non-right angles, and as an example, as shown in fig. 4, the special-shaped display area A3 of the display area 11b may include four non-right angles, that is, fig. 4 shows the display area 11b as a rounded rectangle to improve visual effect. Referring to fig. 7, fig. 7 is a schematic plan view of another display panel according to an embodiment of the present invention, where an edge of the special-shaped display area A3 may include at least one notch, and the notch is generally used to set a functional device, and the functional device may be an optical device such as a camera, an infrared sensor, or the like. The arrangement of the notch can further increase the screen occupation ratio of the display screen, increase the area of the display area and realize the narrow frame design of the special-shaped display panel. Fig. 8 is a schematic plan view of another display panel according to an embodiment of the present invention, and referring to fig. 8, an edge of the special-shaped display area A3 may include a non-right angle and a notch at the same time, so as to further enhance the viewing experience of a user, where the setting situation of the edge of the special-shaped display area A3 is not limited.
Alternatively, the non-right angle may be a rounded, acute or obtuse angle. Fig. 4 shows a case where the non-right angle is rounded, and in addition, the non-right angle may be an acute angle or an obtuse angle, etc., and the specific form of the non-right angle is not limited in this embodiment.
Alternatively, the notch may be a "U" notch or a drop-shaped notch. The "U" shaped notch is shown in fig. 7 and fig. 8, as shown in fig. 9, fig. 9 is a schematic plan view of another display panel provided by the embodiment of the present invention, and the notch may also be a water drop shaped notch shown in fig. 9, where the water drop shaped notch is capable of further increasing the area of the display area compared with the "U" shaped notch, so as to implement a narrow frame design of the special-shaped display panel.
Alternatively, with continued reference to fig. 6, the orthographic projection of the metal connection line 123 on the display panel may be disposed around at least a portion of the subpixels 111 near the edge of the shaped display area A3. In this embodiment, the metal connection line 123 is disposed as close to the sub-pixel 111 at the edge of the special-shaped display area A3 as possible while ensuring that the metal connection line 123 does not block the sub-pixel 111 at the edge of the special-shaped display area A3, i.e., the metal connection line 123 may be disposed around a part of the edges of the sub-pixel 111. Specifically, referring to fig. 10, fig. 10 is a schematic structural diagram of an area A4 in fig. 6, in which a sub-pixel 111a exists in a sub-pixel 111 existing near an edge of a special-shaped display area A3, according to an original extending trend of a metal connection line 123, the metal connection line 123 covers a part of the sub-pixel 111a, in this embodiment, the metal connection line 123 is provided with a fold line portion 123a, the fold line portion 123a is disposed around the sub-pixel 111a, and the fold line portion 123a and a part of the metal grid trace 121 form a mesh 122 together. The metal connection 123 occupies a small space, which is beneficial to realizing the narrow frame design of the special-shaped display panel.
Alternatively, with continued reference to fig. 6, the vertical projection of each mesh 122 of the metal grid trace 121 onto the display panel may surround a corresponding one of the sub-pixels. Fig. 6 shows that the orthographic projection of one mesh 122 on the display panel surrounds one sub-pixel 111, so that the light emitted by the whole display panel is more uniform under the condition that the light emitted by the sub-pixel 111 is not influenced, the metal mesh wires 121 are more densely arranged on the display panel, the detection precision of the touch electrode is higher, the measurement precision of the touch function is improved, and the probability of false touch is reduced. In addition, the front projection of one mesh 122 on the display panel may further include a plurality of subpixels. Illustratively, the display area 11b of the display function layer 11 includes a plurality of pixel units, each pixel unit includes a plurality of sub-pixels of different colors, and the front projection of one mesh 122 on the display panel may surround one pixel unit. For example, if the pixel unit of the display function layer 11 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, the front projection of one mesh 122 on the display panel may enclose the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B in one pixel unit, and if the pixel unit includes a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a white sub-pixel W, the front projection of one mesh 122 on the display panel may enclose the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B, and the white sub-pixel W in one pixel unit. If the orthographic projection of one mesh 122 on the display panel surrounds one pixel unit, the size of the mesh is increased, the setting density of the metal wires is reduced, the etching fineness of the metal wires is reduced, the process manufacturing difficulty of the mesh is reduced, and the process progress is accelerated.
Alternatively, referring to fig. 6, the sub-pixel 111 may include a plurality of sub-pixel columns 112 extending in the second direction Y, each column of sub-pixels 112 including sub-pixels of different colors; the sub-pixel columns 112 are sequentially arranged along the first direction X, and sub-pixels of the same color between two adjacent sub-pixel columns 112 are offset in the second direction Y. As shown in fig. 6, the present embodiment defines that a plurality of sub-pixels 111 sequentially arranged in the second direction Y constitute one sub-pixel column 112, and the plurality of sub-pixel columns 112 are sequentially arranged in the first direction X. Misalignment exists between two adjacent sub-pixel columns 112, so that sub-pixels with the same color are misaligned in the second direction Y, which is convenient for the display panel to realize higher pixel resolution by means of pixel rendering technology (Sub Pixel Rendering, SPR) and improves the picture display definition. Then, corresponding to the touch functional layer 12, the meshes 122 corresponding to the two adjacent sub-pixel columns 112 are also staggered to form a delta arrangement shown in fig. 6. It should be noted that in this embodiment, the first direction X and the second direction Y intersect, and preferably, the first direction X and the second direction Y are perpendicular to each other.
