Fig. 4 is a schematic plan structure diagram of a display panel according to an embodiment of the present invention, fig. 5 is a schematic cross-sectional structure diagram of a display panel according to an embodiment of the present invention, and fig. 6 is a schematic structural diagram of a touch functional layer in an area 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, and the display area 11b includes a special-shaped display area A3, so that the whole display area 11b may be a special-shaped display area, or a partial area of the display area 11b is a special-shaped display area A3, and the rest is a display area with a conventional shape, and the size of the special-shaped display area A3 in the display area 11b is not limited in this embodiment.

The display panel includes a display functional layer 11 and a touch functional layer 12, the touch functional layer 12 is disposed on a light emitting side of the display functional layer 11, the display panel in this embodiment may be a liquid crystal display panel or an organic light emitting display panel, if the display panel is a liquid crystal display panel, the display functional layer 11 is a film layer formed by bonding a backlight, an array substrate and a color film substrate, sub-pixels arranged in an array are formed on the film layer, and each sub-pixel can be controlled individually to perform display. 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-emitting light, an auxiliary light emitting layer for assisting the organic light emitting material layer in emitting 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, which are 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 function layer 11 is disposed on the substrate 13, and the substrate 13 is provided with a driving circuit layer for driving the display function layer 11 to emit light, optionally, because the organic light emitting material layer needs to isolate the water-oxygen environment, a thin film encapsulation layer 14 is generally disposed on the light emitting side of the display function layer 11, and the thin film encapsulation 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 may be disposed by using the thin film encapsulation layer 14 as a substrate, and a glass substrate does not need to be disposed for the touch functional layer 12, so as to reduce the thickness of the entire display panel, which is beneficial to the light and thin configuration of the display panel.
With reference to fig. 4, the display area of the touch functional layer 12 includes a plurality of touch electrodes 124, each touch electrode 124 is formed by a metal grid wire 121, and the metal grid wires 121 are disposed in a gap area between adjacent sub-pixels, and with reference to fig. 6, an orthographic projection of the metal grid wires 121 on the display panel is not overlapped with the sub-pixels 111, so that light emitted from the sub-pixels 111 is not blocked. The touch functional layer 12 includes a single layer of metal grid traces 121, and adjacent touch electrodes 124 can 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 disposed between adjacent touch electrodes 124, and the space is uniformly distributed in the entire touch functional layer 12, so that the display brightness of the display panel is uniform, and the problem of visibility of the outline of the touch electrode 124 is avoided.
With continued reference to fig. 4 and fig. 6, in the touch functional layer 12, the metal connection lines 123 surrounding the metal grid lines 121 are disposed at the outer edges of the metal grid lines 121, because the edges of the irregular display area A3 are arc-shaped or non-linear, the metal connection lines 123 are not linear, in this embodiment, when the metal connection lines 123 are formed, although the metal connection lines 123 are not linear, the orthographic projection of the metal connection lines 123 on the display panel does not overlap with the orthographic projection of the sub-pixels 111 at the edges of the irregular display area A3 on the display panel. The embodiment avoids the problem that the non-linear metal connecting line 123 easily covers the sub-pixel 111 arranged along the edge of the special-shaped display area a3, so that the opening light emitting area of the sub-pixel 111 is not covered, 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, part of the sub-pixels 111 are shielded by the metal connecting line 123, and part of the sub-pixels 111 are not shielded by the metal connecting line 123, 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.
On the basis of the above embodiment, 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 shaped display area A3 includes a non-right angle is shown, and the shaped display area A3 may include one or more non-right angles, and for example, as shown in fig. 4, the shaped display area A3 of the display area 11b may include four non-right angles, that is, fig. 4 shows the display area 11b having a rounded rectangle, to improve the visual effect. Referring to fig. 7, fig. 7 is a schematic plan view illustrating another display panel according to an embodiment of the present invention, an edge of the special-shaped display area a3 may include at least one notch, and the notch is generally used for disposing a functional device, where the functional device may be an optical device such as a camera or an infrared sensor.

Alternatively, the non-right angle may be a rounded angle, an acute angle, or an obtuse angle. Fig. 4 shows a case where the non-right angle is a rounded angle, and in addition, the non-right angle may be an acute angle, an obtuse angle, or the like, and the present embodiment does not limit the specific form of the non-right angle.
Optionally, the notch may be a "U" shaped notch or a drop shaped notch. Fig. 7 and 8 both show a "U" shaped notch, as shown in fig. 9, fig. 9 is a schematic plan structure diagram of another display panel provided in the embodiment of the present invention, and the notch may also be a drop-shaped notch shown in fig. 9, and the drop-shaped notch can further increase 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 connecting line 123 on the display panel may be disposed around at least a portion of the sub-pixels 111 near the edge of the shaped display area a 3. In this embodiment, while it is ensured that the metal connection line 123 does not block the sub-pixel 111 at the edge of the special-shaped display area A3, the metal connection line 123 is disposed as close as possible to the sub-pixel 111 at the edge of the special-shaped display area A3, that is, the metal connection line 123 may be disposed around the edge of part of the sub-pixel 111. Specifically, referring to fig. 10, fig. 10 is a schematic structural diagram of the area a4 in fig. 6, where a sub-pixel 111a exists in a sub-pixel 111 existing near an edge of the irregular display area A3, and the metal connecting line 123 covers a part of the sub-pixel 111a according to an original extending trend of the metal connecting line 123, in this embodiment, the metal connecting line 123 is provided with a polygonal line portion 123a, the polygonal line portion 123a is disposed around the sub-pixel 111a, and the polygonal line portion 123a and a part of the metal grid wire 121 form a mesh 122 together.

Fig. 6 shows a case that the orthographic projection of one mesh 122 on the display panel surrounds one sub-pixel 111, so that the light emission of the whole display panel is more uniform without affecting the light emission of the sub-pixel 111, the metal mesh wires 121 are arranged more densely 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 mistaken touch is reduced. In addition, the orthographic projection of one mesh 122 on the display panel may also include a plurality of sub-pixels. 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 orthographic 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 red, green and blue sub-pixels R, G and B, the front projection of one mesh 122 on the display panel may surround the red, green and blue sub-pixels R, G and B in one pixel unit, and if the pixel unit includes the red, green, blue and white sub-pixels R, G and W, the front projection of one mesh 122 on the display panel may surround the red, green and blue sub-pixels R, G and B and 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 grid is increased, the arrangement density of the metal wires is reduced, the etching fineness of the metal wires is reduced, the process manufacturing difficulty of the grid is reduced, and the process progress is accelerated.

The adjacent two Sub-Pixel columns 112 are staggered, so that the Sub-pixels with the same color are staggered along the second direction Y, which is convenient for the display panel to realize higher Pixel resolution by means of a Pixel Rendering (SPR) technology, and improve the image display definition. The meshes 122 corresponding to the two adjacent sub-pixel rows 112 corresponding to the touch functional layer 12 are also staggered to form a delta-shaped arrangement as shown in fig. 6.
