The side of the pixel layer 12 facing the cover plate 17 is provided with a molding layer 25.

As shown in fig. 11, fig. 11 is a cross-sectional view of the display panel shown in fig. 8 along a direction B-B', and based on the above embodiment, in the manner shown in fig. 11, the pixel layer 12 includes a plurality of dummy sub-pixels 123, and a vertical projection of the dummy sub-pixels 123 on the array substrate 11 is located within a vertical projection of the light shielding structure 13 on the array substrate 11.

The dummy sub-pixel 123 is covered by the shielding structure 13, and does not need to display an image and is not connected to a driving circuit. Since the pixel defining layer 124 is not provided with a pixel groove in a region corresponding to the dummy sub-pixel 123, the dummy organic light emitting layer 128 can be insulated and disconnected from the corresponding dummy anode 126 by the pixel defining layer 124.

In the method, the anode metal layer of the OLED is reused to prepare the reflection layer 21, the display sub-pixel 121 covered by the light shielding structure 13 is disconnected from the driving circuit to serve as the dummy sub-pixel 123, only the mask patterns of the pixel definition layer 124 and the anode metal layer corresponding to the position of the dummy sub-pixel 123 need to be changed, the structure of the panel film layer does not need to be added, and the manufacturing process is simple.

In order to increase the compatibility with the existing process flow without changing the layout of the via holes under the anode layer, the via holes (not shown in fig. 11) that are provided for the dummy sub-pixels 123 and connected to the driving circuit 115 are reserved for each dummy sub-pixel 123 corresponding to the pixel definition layer 124, and the pixel definition layer 124 is provided between the dummy sub-pixels 123 and the via holes 123 under. Since the OLED thickness is thin and the flatness needs to be adjusted by the planarization layer, the staggered arrangement of the dummy sub-pixel 123 and the display sub-pixel 121 does not affect the uniformity of the panel thickness.

The pixel layer 12 includes a plurality of dummy sub-pixels 123. The vertical projection of the dummy sub-pixel 123 on the array substrate 11 is located within the vertical projection of the light shielding structure 13 on the array substrate 11; the dummy sub-pixel 123 includes a dummy anode 126 of the same metal layer as the anode 122, the reflective layer 21 is integrally connected to the dummy anode 126, and the dummy anode 126 is insulated from the driving circuit 115. In the manner shown in fig. 11, the dummy sub-pixel 123 may be insulated from the driving circuit 115 by the pixel defining layer 124.

In other embodiments, the mask of the pixel defining layer 124 may not be changed, so that the corresponding dummy sub-pixel 123 also has a pixel recess, and the via hole 24 communicating with the driving circuit 115 is not disposed below the pixel recess corresponding to the dummy sub-pixel 123, that is, the insulating layer 114 is disposed between the dummy anode of the dummy sub-pixel 123 and the driving circuit 115, so as to realize the open circuit between the dummy sub-pixel 123 and the driving circuit 115.

The side of the pixel layer 12 facing the cover plate 17 is provided with a transparent conducting layer, and the transparent conducting layer is a common cathode of the display sub-pixels; the surface provided with the transparent conductive layer is provided with the reflecting layer. The light shielding structure 13 is located in the transparent conductive layer at a position of vertical projection of the plane of the transparent conductive layer. In this way, the common cathode can be reused as a substrate to form the reflective layer 21, the manufacturing process is simple, and the common cathode has a full-face electrode structure and is provided with the reflective layer 21 with a shape and a size enough for spatial layout.

It is also possible to provide that the touch layer 27 comprises the reflective layer 21, the reflective layer 21 having a gap with the ring of conductors 19. At this time, the touch layer 27 is reused to manufacture the reflective layer 21, the touch electrode 27 can manufacture the touch electrode 271 with a set metal pattern, and the metal patterning process has high precision and can accurately form the reflective layer 21 with a required size at a required position.

As shown in fig. 12 and 13, fig. 12 is a top view of another display panel provided in the present embodiment, and fig. 13 is a cross-sectional view of the display panel shown in fig. 12 along a-a', based on the above embodiment, in the manner shown in fig. 12 and 13, a touch layer 27 is disposed between the pixel layer 12 and the cover 17, where the touch layer 27 includes: a touch electrode 271 and the conductor loop 19. The conductor ring 19 is made through the touch layer 27 without separately adding a metal layer. The vertical projection of the touch electrode 271 on the array substrate 11 and the vertical projection of the conductor ring 19 on the array substrate 11 have a gap greater than 0, and the gap has a width X. To avoid light leakage and capacitance compensation effect during touch control, the width X is small, and the patterning process of the metal layer 27 can meet the requirement of the small width X.

The ink layer 18 has a circular arc outer edge surrounding the hollow area, and a vertical projection of the circular arc outer edge on the array substrate 11 is located in a vertical projection of the corresponding conductor ring 19 on the array substrate 11; the touch layer 27 has windows 272 corresponding to the hollow-out areas one by one, the windows 272 surround the corresponding hollow-out areas 14, and a gap is formed between the window 272 and the corresponding arc-shaped outer edge, and the width of the gap is Y. Since the ink layer 18 is formed after the touch layer 27 is formed, the width Y is large because the printing accuracy of the ink layer 18 is low

The circular arc outer edge has a gap with the outer circular ring edge of the conductor ring 19, and the gap has a width Z. On the premise of high screen ratio design, based on the precision of the current manufacturing process, it is necessary to have a gap with a width of X, Y, Z. The greater width Z results because the greater width Y, the lesser width X, and the greater width Z is approximately equal to Y-X.

The display panel is generally provided with a polarizer, which may be disposed on a side of the cover plate 17 facing the array substrate 11 or a side facing away from the array substrate 11. When the mirror reflection is under the polarizer, the color is darker, and the color is relatively less black when diffuse scattering.

As shown in fig. 14, fig. 14 is a schematic view of a display effect of a display panel according to an embodiment of the present application. As shown in fig. 12, 13 and 14, the conductive ring 19 is exposed at the upper and lower portions of the conductive ring 19 in fig. 12, and has a mirror reflection of the conductive ring 19, so that a darker display effect is formed, if the reflective layer 21 is not provided, the area corresponding to the reflective layer 21 is a normal display area, the touch electrodes 271 of the grid metal are sparse metal wires, so that the mirror reflection cannot be formed, and normal display is possible, and the area corresponding to the reflective layer 21 cannot have the same darker non-display effect, so that the non-display area shown in fig. 14 has a narrower area with a non-smooth connection in the middle. If the scheme of the embodiment of the application is adopted, the reflective layer is arranged, so that the middle of the non-display area can be in smooth transition, and the display effect as shown in the right diagram in fig. 14 is formed.

The above embodiment is described by taking only two hollow-out areas 14 as an example. It should be noted that the centers of all the hollow areas 14 may be located on the same straight line.

N hollow-out areas 14 can also be arranged, wherein N is a positive integer greater than 2, and a central connecting line of the hollow-out areas 14 forms an N-shaped polygon.
