With the rapid development of an AMOLED (Active Matrix Organic Light-Emitting Diode) display device, a full-screen, a narrow frame, high resolution, a flexible wearing, a folding, and the like become important development directions of the future AMOLED.

The technology of directly fabricating the touch structure on the package layer of the OLED (Organic Light-Emitting Diode) display panel can be used to fabricate a lighter and thinner touch panel, and the technology can be applied to a folded and curled OLED display device.

Based on the consideration of reducing resistance, improving touch sensitivity and the like, the touch electrode in the touch structure adopts a metal grid with the advantages of small resistance, small thickness, high response speed and the like. In the related art, the touch structure directly fabricated On the package Layer of the display panel includes two types, a Flexible multi-Layer cover surface type (FMLOC) and a Flexible Single-Layer cover surface type (FSLOC), wherein the FSLOC is more convenient for product thinning than the FMLOC.

The inventor of the present disclosure finds that, under light irradiation, the metal mesh of the touch structure located on the light exit side of the display substrate forms continuous reflected light in the same direction due to the metal reflection effect, and human eyes receiving the reflected light can easily recognize the metal mesh, thereby reducing the display effect.

Based on this, as shown in fig. 18, some embodiments of the present disclosure provide a display panel 900 applied to a touch display device, as shown in fig. 19 and 20. The touch display device may be an electroluminescent display device or a photoluminescent display device. In the case where the Display device is an electroluminescent Display device, the electroluminescent Display device may be an Organic Light-Emitting Display device (OLED), a Quantum Dot electroluminescent Display device (QLED), a Liquid Crystal Display device (LCD), or an Electrophoretic Display device (EPD). In the case that the touch display device is a photoluminescence display device, the photoluminescence display device may be a quantum dot photoluminescence display device.

The exemplary embodiments of the present disclosure are illustrated with OLED display devices, but should not be construed as being limited to the OLED display devices. In some embodiments, as shown in fig. 19 and fig. 20, the main structure of the touch display device includes a display panel 900, a touch structure 1000, an anti-reflection structure such as a polarizer 500, a first optical Adhesive (OCA) layer 600, and a cover plate 300, which are sequentially disposed. In some embodiments, the anti-reflective structure may include a color filter and a black matrix.

The display panel 900 includes a display substrate 200 and an encapsulation layer 250 for encapsulating the display substrate 200. Here, the encapsulation layer 250 may be an encapsulation film or an encapsulation substrate.

In some embodiments, as shown in fig. 14, the touch structure 1000 of the display panel 900 is directly disposed on the encapsulation layer 250, so that the display substrate 200 can be regarded as a substrate of the touch structure 1000, which is beneficial to realizing the lightness and thinness of the display device.

In some embodiments, the encapsulation layer 250 may include a first inorganic encapsulation layer, a first organic encapsulation layer, and a second inorganic encapsulation layer, and may also be a stacked structure of at least one organic layer and at least one inorganic layer. In some embodiments, an anti-reflection structure may be formed in the encapsulation layer 250 to play an anti-reflection role, and at the same time, the thickness of the display device may be further reduced.

In other embodiments, as shown in fig. 20, the touch structure 1000 of the display panel 900 is disposed on the substrate 910, and the substrate 910 is attached to the package layer 250 through the second optical adhesive layer 920. The material of the base substrate 910 may be, for example, Polyethylene terephthalate (PET), Polyimide (PI), Cyclic Olefin Polymer (COP), or the like.

As shown in fig. 18 to 20, each sub-pixel of the above-described display substrate 200 includes a light emitting device and a driving circuit disposed on a substrate 210, and the driving circuit includes a plurality of thin film transistors 270. The light emitting device includes an anode 222, a light emitting layer 223, and a cathode 224, and the anode 222 is electrically connected to a drain of a thin film transistor 270 as a driving transistor among a plurality of thin film transistors 270 of a driving circuit.

In some embodiments, the anode 222 is electrically connected to the drain of the thin film transistor 270 of the plurality of thin film transistors 270 of the driving circuit, which is used as the driving transistor, through a via electrode, and the via electrode is located between the layer where the drain is located and the layer where the anode is located.

The display substrate 200 further includes a pixel defining layer 225, the pixel defining layer 225 includes a plurality of light outlets 225A, and one light emitting device is disposed corresponding to one light outlet 225A.

In some embodiments, the display functional layer 220 includes a light emitting layer 223. In other embodiments, the display function Layer 220 includes one or more of an Electron Transport Layer (ETL), an Electron Injection Layer (EIL), a Hole Transport Layer (HTL), and a Hole Injection Layer (HIL) in addition to the light emitting Layer 223.

As shown in fig. 19 and 20, the display substrate 200 further includes at least one planarization layer 230 disposed between the thin film transistor 270 and the anode 222. In some embodiments, at least one passivation layer is further included on the planarization layer 230.

When the touch display device is an electroluminescent display device, the touch display device may be a top emission type display device, in which case the anode 222 near the substrate 210 is opaque and the cathode 224 far from the substrate 210 is transparent or translucent; the touch display device may also be a bottom emission type display device, in which case the anode 222 near the substrate 210 is transparent or semi-transparent and the cathode 224 far from the substrate 210 is opaque; the touch display device may also be a dual emission type display device, in which case the anode 222 near the substrate 210 and the cathode 224 far from the substrate 210 are transparent or translucent.

As shown in fig. 1, some embodiments of the present disclosure provide a touch structure 1000, including: metal grid 100, metal grid 100 includes a plurality of metal wires 110.

The metal grid 100 has a plurality of openings 100A, each opening 100A is surrounded by a plurality of metal wires 110, and the shape of each opening 100A is asymmetric.

The touch Area of the touch structure 1000 may overlap with a display Area AA (also called an Active Area) in the display substrate 200.

As shown in fig. 2A and 2B, the open arrows at the lower part of the figure represent incident light, and the black line arrows represent reflected light. As shown in fig. 2A, in the case that the openings are symmetrical, incident light in one direction is reflected by the openings, the direction of the obtained reflected light is small, and light rays in each reflection direction are concentrated, so that continuous reflected light is easily formed in the same direction, and the metal mesh is recognized by human eyes.

As shown in fig. 2B, when the openings are asymmetric, incident light in one direction is reflected by the openings, and the directions of the obtained reflected light are more, and light in each reflection direction is more dispersed, so that a quasi-scattering effect is achieved, human eyes cannot perceive the reflected light, and visibility of human eyes to the metal mesh is eliminated or reduced.

Therefore, by setting the shape of the opening 100A to be asymmetric, the extending direction of the metal wire 110 in the metal mesh 100 can be increased, so that the reflected light direction of the whole metal mesh 100 is increased, the effect of light scattering is achieved or approached, and the phenomenon that the metal mesh 100 forms continuous reflected light in the same direction is eliminated or reduced, thereby eliminating or reducing the visibility of human eyes to the metal mesh and improving the display effect.

In addition, when the external light is emitted to the display panel, the metal mesh 100 of the touch structure 1000 near the surface layer reflects the external light, which is a main cause of the Mura phenomenon (uneven brightness display, various traces display). Some embodiments of the present disclosure can achieve the scattering effect of the reflected light by the above-mentioned asymmetric shape design of the opening 100A, and can also eliminate or reduce the Mura phenomenon of the display panel 900, thereby improving the display effect of the display panel 900.

In some embodiments, at least one metal wire 110 of the plurality of metal wires 110 included in one opening 100A may include at least one discontinuity 110A, as shown in fig. 3. Wherein the shapes of the ends of the different interruptions 110A can be the same or different. Illustratively, the end shapes of the two interruptions 110A of the same metal wire 110 may be different; or, the end shapes of the fractures 110A of the same metal wire 110 are the same, and the end shapes of the fractures 110A of different metal wires 110 are different; alternatively, the shapes of the end portions of the interruptions 110A of the plurality of metal wires 110 are all the same; alternatively, the end portions of the interruptions 110A of the plurality of metal wires 110 are all different in shape.

The widths of the plurality of metal wires 110 included in one opening 100A may be the same or different. Illustratively, one opening 100A includes a plurality of metal wires 110 each having the same width; alternatively, one opening 100A includes a plurality of metal wires 110 having different widths; alternatively, one opening 100A includes a plurality of metal wires 110, wherein the width of one part of the metal wires 110 is the same, the width of the other part of the metal wires 110 is the same, and the widths of the two parts of the metal wires 110 are different.

It is to be noted that, in the case where two metal wires 110 have the discontinuity 110A of the same end shape, the end size of the discontinuity 110A is also different due to the difference in width of the two metal wires 110.

Due to the design of the fractures 110A, fig. 3 can reduce the metal reflecting light in the openings 100A compared with fig. 2B, thereby further reducing the reflected light of the metal grid 100 and eliminating or reducing the visibility of the metal grid to human eyes.

In some embodiments, the opening 100A is defined by N metal wires 110 connected end to end, where the N metal wires 110 have M different extending directions; n and M are integers, N is not less than 5, and M is not less than 3 and not more than N.

The two metal wires 110 having the same extending direction means that the two metal wires 110 are parallel to each other, and the two metal wires 110 having different extending directions means that the two metal wires 110 cross, or the extension lines of the two metal wires 110 cross. Illustratively, the number N of metal conductors surrounding the opening 100A may be 5, 7, 9, 10, or 15. For example, in the case where the number of the metal wires surrounding the opening 100A is 5, the extending directions of the 5 metal wires may be 3, 4, or 5. Under the condition that M is equal to N, the extending directions of N metal wires which enclose the opening are different; and under the condition that M is less than N, the extending directions of at least two metal wires are the same.

As shown in fig. 4, the point 1, the point 2, and the point 3 are located on the same straight line and are three position points on the metal wire, which in some implementations of the present disclosure is considered to include one straight metal wire having the point 1 and the point 2 as end points and another straight metal wire having the point 2 and the point 3 as end points.

Illustratively, opening 100A (I) is defined by line segment 12, line segment 23, line segment 34, line segment 45, line segment 56, line segment 67, and line segment 71, and opening 100A (II) is defined by line segment 23, line segment 38, line segment 89, line segment 90, and line segment 02. It should be noted that the line segments are all representative metal wires in the metal grid 100.

Under the condition that the number of the metal wires 110 enclosing the opening 100A is greater than or equal to 8 sides and the included angle between each side and the horizontal direction is greater than or equal to 4, the opening 100A can better realize the effect of scattering light.

Illustratively, as with the three openings 100A in fig. 1, the first type of opening 100A1 is bounded by 6 sides, the second type of opening 100A2 is bounded by 10 sides, and the third type of opening 100A3 is bounded by 14 sides. The metal wires 110 of the three openings 100A have 7 different included angles with the horizontal direction, so that the light can be well scattered.

The more N and M, the more the reflection light direction of the metal grid is, the more the effect of light scattering can be approached, and the phenomenon that the metal grid forms continuous reflection light in the same direction is eliminated or lightened, so that the visibility of human eyes to the metal grid is more conveniently eliminated or lightened, and the display effect is improved.

In some embodiments, any two metal wires 110 of the at least N metal wires 110 are not symmetrical to each other.

The two metal wires 110 are not symmetrical, and the extending directions of the two metal wires 110 are symmetrical and the extending lengths are different; or the extending directions of the two metal wires are asymmetric, and the extending lengths are the same; or the extending directions of the two metal wires are asymmetric, and the extending lengths are different.

Any two metal wires 110 in the N metal wires 110 that together enclose the opening 100A are not symmetrical to each other, and for the metal wires 110 that enclose the opening 100A include two symmetrical metal wires 110, the reflection direction of the metal wires 110 to incident light can be increased, and the amount of reflected light in each reflection direction is weakened, so that the light is further scattered. Therefore, the overall reflected light direction of the metal grid 100 can be further increased, so that the visibility of human eyes to the metal grid 100 can be eliminated or reduced, and the display effect can be improved.

In some embodiments, the metal grid 100 includes at least one type of openings 100A, each type of openings 100A includes a plurality of openings 100A having the same shape, and the openings 100A of different types have different shapes.

The metal mesh 100 includes one or more types of openings 100A, and illustratively, as shown in the enlarged view of fig. 1, the metal mesh 100 includes three types of openings 100A, a first type of openings 100A1 having a shape that is 6-sided asymmetric, a second type of openings 100A2 having a shape that is 10-sided asymmetric, and a third type of openings 100A3 having a shape that is 14-sided asymmetric. The number of sides of the different types of openings 100A may be the same but the shapes may be different, and the above description is given only by way of example of the different number of sides.

In a display device with pixel density of more than 500PPI (Pixel Per Inc.), touch electrodes arranged in an array with side length of less than 0.3mm which can not be recognized by human eyes can be formed through opening design of a metal grid, and the defect of visible display of the driving electrodes formed by the side length of 3-5 mm by the human eyes is eliminated. For a display device with a medium-size and large-size pixel density of less than 400PPI, the openings of the metal grid 100 are limited by the resistance-capacitance load due to the large area of the light emitting region of the sub-pixels, and the side length of the minimum touch electrode formed by designing the openings 100A is generally greater than 0.3mm, so that the visible display defect can be easily identified by human eyes.

The outline sides of the light emitting region 221A enclosing one sub-pixel 221 may be both straight outline sides, or both arc outline sides, or a part of the straight outline sides, and the rest of the arc outline sides. When the outline sides of the light-emitting regions 221A surrounding the sub-pixels 221 are all straight outline sides, the light-emitting regions 221A of the sub-pixels 221 are Asymmetric Polygon Pixels (APPs).

Illustratively, the number N of sides enclosing the light emitting region 221A may be 5, 7, 9, 10, or 15. For example, in the case where the number of the metal wires surrounding the opening 100A is 5, the extending directions of the 5 metal wires may be 3, 4, or 5. Under the condition that M is equal to N, the extending directions of N metal wires which enclose the opening are different; and under the condition that M is less than N, the extending directions of at least two metal wires are the same.

In some embodiments, any two of the N edges are asymmetric with respect to each other. The two sides are not symmetrical, and the extending directions of the two sides are symmetrical and the extending lengths are different; or the extending directions of the two edges are asymmetric, and the extending lengths are the same; alternatively, the extending directions of the two sides are asymmetric, and the extending lengths are different.

In some embodiments, the display function layer 220 includes a plurality of color sub-pixels 221, and the outline of the light emitting region 221A of at least one color sub-pixel 221 is surrounded by more than 8 lines in an end-to-end manner.

In some embodiments, the light emitting regions 221A of the sub-pixels 221 of different colors have different shapes and/or different areas.

The different shapes of the light-emitting regions 221A of the sub-pixels 221 of different colors mean that the shape of the light-emitting region 221A of one color of the sub-pixel 221 is different from the shape of the light-emitting regions 221A of the sub-pixels 221 of the other colors. Here, the shape of the light emitting region 221A of the sub-pixel 221 of one color may be one or more, and in the case where the shape of the light emitting region 221A of the sub-pixel 221 of one color is plural, the shape of the light emitting region 221A of the sub-pixel 221 of the other color is not the same as any of the plural shapes.

The different areas of the light-emitting regions 221A of the sub-pixels 221 of different colors mean that the area of the light-emitting region of the sub-pixel 221 of one color is different from the area of the light-emitting region 221A of the sub-pixel 221 of another color. Here, the area of the light emitting region 221A of the sub-pixel 221 of one color may be one or more, and in the case where the area of the light emitting region 221A of the sub-pixel 221 of one color is more than one, the areas of the light emitting regions 221A of the sub-pixels 221 of the other colors are not the same as any of the more than one area.

Illustratively, the areas of the light emitting regions 221A of the sub-pixels 221 of one color include an area 1 and an area 2, and the areas of the light emitting regions 221A of the sub-pixels 221 of the other colors are different from the areas of the area 1 and the area 2.

The light emitting regions 221A of the sub-pixels 221 of different colors may have different shapes and areas, may have the same shape but different areas, or may have different shapes but the same areas.

Illustratively, the shape of the light emitting region of the blue sub-pixel is the same as that of the light emitting region of the red sub-pixel, but the area of the light emitting region of the blue sub-pixel is different from that of the light emitting region of the red sub-pixel.

Illustratively, the shape of the light emitting region of the blue sub-pixel is different from the shape of the light emitting region of the white sub-pixel, but the area of the light emitting region of the blue sub-pixel is the same as the area of the light emitting region of the white sub-pixel.

In some embodiments, as shown in fig. 10, the display function layer includes: a pixel defining layer 225 provided with a plurality of light outlets 225A, each light outlet 225A defining a light emitting region 221A of a sub-pixel; the light outlet 225A has substantially the same shape as the light emitting region 221A of the sub-pixel 221.

The pixel defining layer 225 is similar to a grid structure, and a plurality of light outlets 225A are defined by the barriers, one light outlet 225A is arranged in one sub-pixel region, the light outlet 225A is configured to determine a light emitting region 221A of the sub-pixel 221, and light emitted by the light emitting layer 223 passes through the light outlet 225A to obtain the light emitting region 221A. Therefore, the shape of the light exit 225A is substantially the same as the shape of the light-emitting region 221A of the sub-pixel 221.

The plurality of light outlets 225A of the light emitting regions 221A of the sub-pixels 221 arranged in the same color in the pixel defining layer 225 may be in the same shape, and the light outlets 225A of the light emitting regions 221A of the sub-pixels 221 arranged in different colors may be in different shapes.

In some embodiments, as shown in fig. 11, the display function layer 220 includes a blue sub-pixel B, a red sub-pixel R, and a green sub-pixel G, wherein an area of the light emitting region 221A of the blue sub-pixel B is larger than an area of the light emitting region 221A of the red sub-pixel R, and an area of the light emitting region 221A of the red sub-pixel R is larger than an area of the light emitting region 221A of the green sub-pixel G;

the pixel defining layer 225 includes a first light outlet 225a1, a second light outlet 225a2, and a third light outlet 225 A3; the first light outlet 225a1 is configured to define the light-emitting region 221A of the blue sub-pixel B, the second light outlet 225a2 is configured to define the light-emitting region 221A of the red sub-pixel R, and the third light outlet 225A3 is configured to define the light-emitting region 221A of the green sub-pixel G;

the opening area of the first light outlet 225a1 is larger than that of the second light outlet 225a2, and the opening area of the second light outlet 225a2 is larger than that of the third light outlet 225 A3.

The display function layer 220 includes a blue sub-pixel B, a red sub-pixel R, and a green sub-pixel G, but is not limited to the above three sub-pixels, and may include other sub-pixels such as a white sub-pixel. The above is merely exemplified by using the blue sub-pixel, the red sub-pixel and the green sub-pixel.

A first light outlet 225A1 of the light outlets 225A in the pixel defining layer 225 is located in the area of the blue sub-pixel B, and light emitted by the light emitting layer 223 of the blue sub-pixel B passes through the first light outlet 225A1, so that a light emitting region 221A of the blue sub-pixel B is obtained; a second light outlet 225A2 of the light outlets 225A in the pixel defining layer 225 is located in the red sub-pixel R region, and light emitted by the light emitting layer 223 of the red sub-pixel R passes through the second light outlet 225A2, so as to obtain a light emitting region 221A of the red sub-pixel R; the third light outlet 225A3 of the plurality of light outlets 225A in the pixel defining layer 225 is located in the green sub-pixel G area, and the light emitted from the light emitting layer 223 of the green sub-pixel G passes through the third light outlet 225A3, so as to obtain the light emitting region 221A of the green sub-pixel G.

Human eyes have different color sensitivities, and the human eyes specifically have the following color sensitivities: for this reason, the area of the light emitting region 221A of the blue sub-pixel B is larger than that of the light emitting region 221A of the red sub-pixel R, and the area of the light emitting region 221A of the red sub-pixel R is larger than that of the light emitting region 221A of the green sub-pixel G, so that the human eyes can feel balance of light of various colors, the redundancy of the sub-pixels is reduced, and the aperture ratio and the resolution are improved.

The encapsulation layer 250 covers the light emitting device 240, and the touch structure 1000 is formed on the encapsulation layer 250. In some embodiments, in a case that the light emitting side of the display substrate 200 may further include an anti-reflection structure (e.g., a circular polarizer), the touch structure 1000 is formed between the encapsulation layer 250 and the anti-reflection structure, and the metal mesh 100 may be directly formed on the surface of the encapsulation layer 250, that is, there is no other film layer between the metal mesh 100 and the surface of the encapsulation layer 250.

In some embodiments, as shown in fig. 12, an orthogonal projection 221AT of the light emitting region 221A of AT least one sub-pixel 221 of the display substrate 200 on the substrate 210 of the display substrate 200 is located within an orthogonal projection 100AT of one opening 100A of the metal mesh 110 of the touch structure 1000 on the substrate 210 of the display substrate 200.

An orthographic projection 221AT of the light emitting region 221A of one sub-pixel 221 on the substrate 210 is positioned in an orthographic projection 100AT of one opening 100A of the metal grid 100 on the substrate 210; alternatively, the orthographic projection 221AT of the light emitting regions 221A of the plurality of sub-pixels 221 on the substrate 210 is located within the orthographic projection of one opening 100A of the metal mesh 100 on the substrate 210, as shown in fig. 14; alternatively, the orthographic projections 221AT of the light emitting regions 221A of the plurality of sub-pixels 221 on the substrate 210 are respectively located within the orthographic projections 100AT of the plurality of openings 100A of the metal mesh 100 on the substrate 210, as shown in fig. 15.

Illustratively, the orthographic projections 221AT of the light emitting areas 221A of the two sub-pixels 221 on the substrate 210 are co-located within the orthographic projection 100AT of one opening 100A of the metal mesh 100 on the substrate 210, as shown in fig. 14; alternatively, the orthographic projections 221AT of the light emitting regions 221A of the four sub-pixels 221 on the substrate 210 are respectively located within the orthographic projections 100AT of the four openings 100A of the metal mesh 100 on the substrate, as shown in fig. 15.

That is, a part of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 AT least partially coincides with the orthographic projection 100AT of one opening 100A of the metal mesh 100 on the substrate 210, and another part of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 AT least partially coincides with the orthographic projection 100AT of the other opening 100A of the metal mesh 100 on the substrate 210.

In some embodiments, an orthogonal projection 221AT of the light emitting region 221A of each sub-pixel 221 on the substrate 210 is located within an orthogonal projection 100AT of one opening 100A of the metal mesh 100 on the substrate 210. That is, the orthographic projection of the light emitting region 221A of each sub-pixel 221 on the substrate 210 is located AT least in a partial region of the orthographic projection 100AT of one opening 100A of the metal mesh 100 on the substrate 210.

The shape of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 may be the same as or different from the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, for example: the orthographic projection 221AT of the light emitting area 221A of the sub-pixel 221 on the substrate 210 is in a 7-polygon structure, and the orthographic projection 100AT of the opening 100A of the metal grid 100 on the substrate 210 is in a 9-polygon structure; alternatively, the shape of the orthographic projection 221AT of the opening 100A of the metal mesh 100 on the substrate 210 and the shape of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210 are two different 8-sided polygonal structures.

The outline of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 and the outline of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210 may AT least partially coincide; the outline of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 may not coincide with the outline of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, that is, a gap 810 is provided between the outline of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 and the outline of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, as shown in fig. 12 to 16.

In the case where the shape of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 is different from the shape of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, the gap width in different directions of the gap 810 between the outline of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 and the outline of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210 may be different, as shown in fig. 14 to 16, where the orthographic projection 221AT of the light emitting region 221A of the same sub-pixel 221 on the substrate 210 is different from the orthographic projection 100AT of the opening 100A on the substrate 210 in different directions.

In addition, in the case that the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 is located AT the edge area of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, the gap 810 between the outline of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 and the outline of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210 may also have different gap widths in different directions.

The metal mesh 100 can be matched with the structure of a conventional sub-pixel, and since the shape of the conventional sub-pixel is a symmetrical structure, the shape of the orthographic projection 221AT of the light emitting region 221A belonging to the sub-pixel 221 on the substrate 210 is different from the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, as shown in fig. 14 to 16. The metal mesh 100 may also be fitted with a sub-pixel structure having a shape corresponding to the shape of the opening 100A, i.e., a case where the shape of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 is the same as the shape of the orthographic projection 100AT of the opening 100A of the metal mesh 100 on the substrate 210, as shown in fig. 12 and 13.

In some embodiments, a gap 810 is provided between the outline of the orthographic projection 221AT of the light emitting region 221A of the AT least one sub-pixel 221 on the substrate 210 and the outline of the orthographic projection 100AT of the one opening 100A on the substrate 210.

That is, the area of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 is smaller than the area of the orthographic projection 100AT of the one opening 100A on the substrate 210, and the contour of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 on the substrate 210 does not intersect within the contour of the orthographic projection 100AT of the one opening 100A on the substrate 210.

The orthographic projection 221AT of the light emitting region 221A of one sub-pixel 221 on the substrate 210 is located within the orthographic projection 100AT of one opening 100A of the metal mesh 100 on the substrate 210, and the contour of the orthographic projection 221AT of the light emitting region 221A of one sub-pixel 221 on the substrate 210 does not intersect within the contour of the orthographic projection 100AT of the one opening 100A on the substrate 210.

The orthographic projection 100AT of the first opening 100A on the substrate 210 covers the orthographic projection 221AT of the light emitting region 221A of one sub-pixel 221 on the substrate 210; the orthographic projection 100A of the second opening 100A on the substrate 210 covers the orthographic projection 221AT of the light emitting region 221A of the other sub-pixel 221 on the substrate 210; the orthographic projection 100A of the third opening 100A on the substrate 210 covers the orthographic projection 221AT of the light emitting region 221A of the other sub-pixel 221 on the substrate 210; the orthographic projection 100A of the fourth opening 100A on the substrate 210 covers the orthographic projection 221AT of the light emitting region 221A of the remaining one sub-pixel 221 on the substrate 210.

In some embodiments, as shown in FIG. 12 and FIG. 13, the pixel unit 820 includes X color sub-pixels 221, the opening unit 120 includes X shape openings 100A, the X color sub-pixels 221 are in one-to-one correspondence with the X shape openings 100A, X is an integer and X ≧ 3.

A first orthographic projection 100AT of the target-shaped opening 100A on the substrate 210 covers a second orthographic projection 221AT of the light emitting region 221A of the target-color sub-pixel 221 on the substrate 210; the target shape is any one of the X shapes, and the target color is a color corresponding to the target shape.

The shape of the first forward projection 100AT is substantially the same as the shape of the second forward projection 221AT, and there is a gap 810 between the contour of the second forward projection 221AT and the contour of the first forward projection 100 AT.

The number of openings 100A in the opening unit 120 is equal to the number of sub-pixels 221 in the pixel unit 820, and the openings 100A of one shape in the opening unit 120 correspond one-to-one to the sub-pixels 221 of one color in the pixel unit 820. The shapes of the different openings 100A in the same opening unit 120 are different from each other.

The first orthographic projection 100AT of each shaped opening 100A on the substrate 210, and the second orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 covering the shaped opening 100A corresponding to the color on the substrate 210.

Illustratively, as shown in fig. 12, the pixel unit 820 includes a blue sub-pixel B, a red sub-pixel R, and a green sub-pixel G; as shown in fig. 1, the opening unit 120 includes a first-shaped opening 100A3 corresponding to the blue sub-pixel B, a second-shaped opening 100a2 corresponding to the red sub-pixel R, and a third-shaped opening 100a1 corresponding to the green sub-pixel G. As shown in fig. 12, a first orthographic projection 100AT1 of the first shaped opening 100a3 on the substrate 210 covers a second orthographic projection 221AT3 of the light emitting region 221A of the blue sub-pixel B on the substrate 210; a first front projection 100AT2 of the second shaped opening 100a2 on the substrate 210 covers a second front projection 221AT2 of the light emitting region 221A of the red subpixel R on the substrate 210; the first orthographic projection 100AT3 of the third shaped opening 100a3 on the substrate 210 covers the second orthographic projection 221AT3 of the light emitting region 221A of the green sub-pixel G on the substrate 210.

The above example may be a case where the number of the subpixels 221 of one color in one pixel unit 820 is one, or a case where the number of the subpixels 221 of one color in one pixel unit 820 is plural. For example: one pixel unit 820 includes two green sub-pixels 221, and the first orthographic projection 100AT3 of the opening 100a3 of the third shape on the substrate 210 covers the second orthographic projection 221AT3 of the light emitting regions 221A of the two green sub-pixels G on the substrate 210.

The shape of the first orthographic projection 100AT is substantially the same as the shape of the second orthographic projection 221AT, that is, the shape of the orthographic projection 100AT of the opening 100A of one shape on the substrate 210 is substantially the same as the shape of the orthographic projection 221AT of the light emitting region 221A of the sub-pixel 221 of the corresponding color on the substrate 210. It can be understood that the shape of one opening 100A is substantially the same as the shape of the sub-pixel 221 of its corresponding color. That is, not only the shape of the opening 100A in the opening unit 120 is in one-to-one correspondence with the color of the sub-pixel 221 in the pixel unit 820, but also the shape of the opening 100A is substantially the same as the shape of the color sub-pixel 221 corresponding to the opening 100A.

Illustratively, the pixel unit 820 includes a fourth-shaped blue sub-pixel 221, a fifth-shaped red sub-pixel 221, and a sixth-shaped green sub-pixel 221; the opening unit 120 includes a fourth-shaped opening 100A corresponding to the blue sub-pixel 221, a fifth-shaped opening 100A corresponding to the red sub-pixel 221, and a sixth-shaped opening 100A corresponding to the green sub-pixel 221.

There is a gap 810 between the contour of the second orthographic projection 221AT and the contour of the first orthographic projection 100AT, i.e. the same shape of the opening 100A and the sub-pixel 221, the area of the orthographic projection 100AT of the opening 100A on the substrate 210 is larger than the area of the orthographic projection 221AT of the sub-pixel 221 on the substrate 210, and the contours of the orthographic projection 221AT of the sub-pixel 221 on the substrate 210 do not intersect within the contour of the orthographic projection 100AT of the opening 100A on the substrate 210.

A gap 810 is formed between the outline of the orthographic projection 221AT of the sub-pixel 221A on the substrate 210 and the outline of the orthographic projection 100AT of the opening 100A on the substrate 210, so that the metal wire 110 which surrounds the opening 100A can be prevented from shielding light rays emitted by the sub-pixel 221 on the light emitting side of the sub-pixel 221, and the light emitting efficiency of the display panel is ensured. Further, the shape of the opening 100A is substantially the same as that of the sub-pixel 221, so that the two contours having the same shape and fitted to each other can achieve a uniform width of the gap 810 in each direction, and the manufacturing area of the sub-pixel can be further enlarged while ensuring the light emitting efficiency of the display panel.

In some embodiments, the vertical separation between the profile of the first forward projection 100AT and the profile of the second forward projection 221AT (i.e., the width of the gap 810 described above) is 8 μm to 12 μm. Wherein the pitch value may be 9 μm, 10 μm, 10.3 μm, 11.1 μm, or 11.8 μm.

The vertical distance may be a straight-line distance between two lines which are parallel to each other and whose vertical lines are at two intersections on the two lines. Illustratively, as shown in fig. 17, line a is a line of the contour of the first orthographic projection 100AT, line B is a line of the contour of the second orthographic projection 221AT, line C is a perpendicular line perpendicular to line a and line B, point D is an intersection of line C and line a, point E is an intersection of line C and line B, and the vertical separation between line a and line B is the linear distance between point D and point E.
