[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] This embodiment provides a display device, which includes a housing and a display panel, the display panel is mounted on the housing and fixed, and a power supply is provided in the housing to power the display panel. As more and more life scenarios require the use of display devices, such as mobile phones, smart watches, car screens, etc., the requirements for display devices are getting higher and higher. In this embodiment, the display device is described by taking a mobile phone as an example.

[0039] like Figure 1As shown, the display panel includes an array substrate 1, an anode layer 2, a pixel definition layer 4, a cathode layer and a light-emitting layer, wherein the cathode layer is a whole cathode plate, the anode layer 2 includes a plurality of anode plates 21, and the plurality of anode plates 21 are arranged below the cathode layer at intervals along the thickness direction of the display panel, the pixel definition layer 4 is used to define and limit the shape and size of the pixel to ensure that each pixel can work correctly, the light-emitting layer includes a plurality of light-emitting units, and the light-emitting unit is located between the corresponding cathode plate and the corresponding anode plate 21, and the array substrate 1 generates a voltage between the corresponding anode plate 21 and the cathode by controlling the anode to be energized, thereby activating the light-emitting unit to emit light, thereby displaying an image.

[0040] Among them, the mobile phone is laid flat as an example for explanation, and the display panel is composed of an array substrate 1, an anode layer 2, a pixel definition layer 4, a light-emitting layer and a cathode layer from bottom to top. The light-emitting unit is made of a light-emitting material that can be activated, and each light-emitting unit is located between a cathode plate and an anode plate 21. The picture displayed on the display panel is formed by the light-emitting unit emitting light of different colors at different positions. Specifically, the light emitted by the light-emitting unit can have three colors, specifically R (red), G (green), and B (blue).

[0041] The inventors have found that the portability of mobile phones makes the use of mobile phones very diverse. If used outdoors or in a bright light environment, external light will illuminate the display panel and will illuminate the thin film transistor 12 through the gap between the film layers. Since most thin film transistors 12 are sensitive to light, strong light will cause light leakage in the thin film transistor 12, affecting the display effect of the display panel.

[0042] like Figure 1 As shown, in order to solve the above problems, in this embodiment, the array substrate 1 includes a substrate 13 and a metal layer 11, the metal layer 11 includes at least one shielding wiring 111, the anode layer 2 is arranged on the side of the metal layer 11 away from the substrate 13, the multiple anode plates 21 of the anode layer 2 are arranged at intervals with each other, and at least one shielding wiring 111 forms a shielding structure, and along the thickness direction of the display panel, the projection of the shielding structure on the substrate 13 covers the gap between the projections of two adjacent anode plates 21 on the substrate 13.

[0043] In the display panel, the anode plate 21 and the shielding wiring 111 are both made of opaque metal materials, so the shielding structure formed by the shielding wiring 111 is used to cover the gap between the anode plates 21. When external light passes through the gap of the anode plate 21, it will be reflected by the shielding wiring 111 corresponding to the gap, avoiding the external light from entering the display panel and directly irradiating the thin film transistor 12 or irradiating it after multiple reflections, preventing the thin film transistor 12 from being affected by external light, and ensuring the display effect of the display panel.

[0044] Since the display device uses the above-mentioned display panel, the user can use it normally under conditions of strong external light, thereby optimizing the user experience and improving the competitiveness of the product.

[0045] It is worth noting that the metal layer 11 may have multiple traces. In this embodiment, the traces that can block external light entering through the gaps in the anode plate 21 are called shielding traces 111. Only the shielding traces 111 form a shielding structure, and other traces do not form a shielding structure.

[0046] Furthermore, the shielding routing 111 can be a regular routing of the metal layer 11. The designer can appropriately adjust the position and width of the nearby routing according to the position and width of the gap between the anode plates 21, so that the routing has a shielding function and becomes the shielding routing 111; when there is no suitable routing near the gap between the anode plates 21, the designer can also design a separate routing without signal transmission function to specifically serve as the shielding routing 111.

[0047] Generally speaking, the gaps between the anode plates 21 are relatively large, which may cause external light to irradiate the inside of the display panel through the gaps between the anode plates 21 and affect the thin film transistors 12 .

[0048] In this embodiment, the area of ​​the anode plate 21 is increased, thereby reducing the gap between two adjacent anode plates 21. It is worth noting that there are gaps between the multiple anode plates 21. In order to improve the shielding effect of external light, the shielding structure can be formed by multiple shielding traces 111, and the shielding structure can shield the gaps between the anode plates 21 within a certain range.

[0049] In this embodiment, along the arrangement direction of two adjacent anode plates 21, the ratio of the gap size between the anode plates 21 and the gap between the two anode plates 21 is 5:1 to 12:1. This ratio makes the total area of ​​the gap between the anode plates 21 much smaller than the total area of ​​the anode plates 21, and can increase the area of ​​the anode plates 21 while ensuring that the anode plates 21 do not touch each other, so that the shielding trace 111 can shield the external light entering through the gap between the anode plates 21.

[0050] Specifically, along the arrangement direction of two adjacent anode plates 21 , the ratio of the gap between the two anode plates 21 may be 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 11:1 or 12:1.

[0051] In some embodiments, the above purpose can also be achieved by widening the width of the shielding wiring 111. This structure can not only reduce the internal resistance of the shielding wiring 111, thereby reducing heat generation and energy consumption, but also ensure that the gap between adjacent anode plates 21 is large, which is convenient for design.

[0052] In some embodiments, along the thickness direction of the display panel, the projection of the shielding structure on the substrate 13 is adjacent to the projections of the corresponding two adjacent anode plates 21 on the substrate 13. Adjacent means that there is neither a gap nor an intersection between the projection of the shielding structure and the projections of the two anode plates 21, and the boundaries of the two projections overlap. In other words, the width of the shielding trace 111 is equal to the spacing between the two anode plates 21 directly above it. This structure can ensure the shielding of the thin film transistor 12 without increasing the wire width or the area of ​​the anode plate 21 too much, thereby preventing external light from irradiating the thin film transistor 12.

[0053] In some embodiments, along the thickness direction of the display panel, the projection of the shielding structure on the substrate 13 overlaps with the projection of the corresponding two adjacent anode plates 21 on the substrate 13. The overlapping means that the projection of the shielding structure intersects with the projections of the two anode plates 21. In other words, the width of the shielding trace 111 is greater than the spacing between the two anode plates 21 directly above the shielding trace 111, so that the shielding structure can better cover the gap between the two adjacent anode plates 21 to avoid light leakage. Moreover, this structure can also have a certain shielding effect on obliquely incident external light, improve the protection of the thin film transistor 12, and ensure the display effect of the display panel.

[0054] In this embodiment, along the thickness direction of the display panel, the projection of the shielding structure on the substrate 13 overlaps or abuts one of the projections of the two adjacent anode plates 21 on the substrate 13, and the projection of the shielding structure on the substrate 13 overlaps or abuts the other of the projections of the two adjacent anode plates 21 on the substrate 13. In other words, the shielding structure only needs to ensure that the gap between the two adjacent anode plates 21 is covered, and the projection of the shielding structure and the projection of the anode plate 21 can overlap or abut, which improves the degree of freedom in design.

[0055] It is worth noting that the thin film transistor 12 includes at least one of a driving transistor and a switching transistor. The more critical thin film transistors 12 (such as the switching transistor, which affects the gate initialization function) are not evenly distributed in the display panel. Therefore, in the display panel, the size of the anode plate 21 or the width of the shielding trace 111 can be designed according to the function of the thin film transistor 12.

[0056] For example, along the thickness direction of the display panel, the projection of the shielding structure on the substrate 13 overlaps with the projection of part of the anode plate 21 on the substrate 13, and the projection of the shielding structure on the substrate 13 is adjacent to the projection of at least other part of the anode plate 21 on the substrate 13. Among them, for the area where the more critical thin film transistor 12 is arranged, the projection of the shielding structure formed by the shielding wiring 111 on the substrate 13 overlaps with the projection of the anode plate 21 on the substrate 13, so as to prevent the external light from irradiating the thin film transistor 12; for the area where the ordinary thin film transistor 12 is arranged, it is only necessary that the projection of the shielding structure formed by the shielding wiring 111 on the substrate 13 is adjacent to the projection of the anode plate 21 on the substrate 13, and when a small amount of external light is incident at an inclined angle, the energy will be partially weakened, and even if it irradiates the thin film transistor 12 in this area, it will not affect the display effect.

[0057] It can be understood that along the thickness direction of the display panel, the projection of the shielding structure on the substrate 13 is adjacent to the projections of the corresponding two adjacent anode plates 21 on the substrate 13, which can make the width of the shielding trace 111 at this location relatively small, thereby facilitating the arrangement of more shielding traces 111, or ensuring that the shielding traces 111 are not easily interfered with each other.

[0058] In some embodiments, since the display panel is small or the display effect of the display panel is required to be high, it is necessary to ensure that all thin film transistors 12 work normally. Figure 2 and Figure 3 As shown, in order to achieve the above purpose, along the thickness direction of the display panel, the overlapping width of the projection of the shielding structure on the substrate 13 and the overlapping anode plates 21 of the corresponding two adjacent anode plates 21 in the projection of the substrate 13 is A, and the distance between the shielding trace 111 forming the shielding structure and the corresponding overlapping anode plates 21 in the thickness direction of the display panel is B, and the ratio of A to B is 1:5 to 1:1.

[0059] This ratio should not be too large or too small. If it is too large, the overlapping area will be too small and the shielding of external light will be affected, so that some external light with a less inclined angle and higher residual energy will be irradiated onto the thin film transistor 12, affecting the operation of the thin film transistor 12. If it is too small, it means that the overlapping area is too large. In one case, the distance between two adjacent anode plates 21 is too close, which increases the design difficulty and the requirements for accuracy. In another case, the shielding wiring 111 is wider, which increases the difficulty of arranging the shielding wiring 111 and increases the cost.

[0060] Specifically, the ratio of A to B may be 1:5, 1:4, 1:3, 1:2 or 1:1.

[0061] like Figure 1 and Figure 4As shown, the array substrate 1 includes multiple metal layers 11, and the wiring of at least one metal layer 11 is used as a shielding wiring 111 to form a shielding structure. The shielding structure can be formed by one or more layers of shielding wiring 111. When the shielding wiring 111 of a certain layer cannot cover the gap between the anode plates 21, the shielding wiring 111 of other layers can be designed to cover it, which improves the degree of freedom in selecting the shielding wiring 111 to form the shielding structure, and is convenient for design.

[0062] Preferably, along the thickness direction of the display panel, a plurality of shielding traces 111 of the metal layer 11 that is the smallest distance from the anode layer 2 form a shielding structure. It is understandable that the farther the shielding trace 111 is from the anode plate 21, the larger the gap between the two along the thickness direction of the display panel. To effectively block the incidence of external light, it is necessary to increase the overlapping area between the two, which means that it is necessary to reduce the gap between two adjacent anode plates 21, or increase the width of the shielding trace 111, thereby increasing the design difficulty. By utilizing a plurality of shielding traces 111 of the metal layer 11 that is the smallest distance from the anode layer 2 in the array substrate 1, the shielding effect of the shielding trace 111 on the gap between the anode plates 21 can be improved.

[0063] In this embodiment, along the thickness direction of the display panel, the projections of the shielding traces 111 of at least two metal layers 11 on the substrate 13 overlap or abut to form a shielding structure. In other words, the gap between two adjacent anode plates 21 can be shielded by two or more shielding traces 111 of different layers, further improving the degree of freedom in designing the traces 111.

[0064] It is worth noting that the multiple shielding traces 111 of the metal layer 11 which is the smallest distance from the anode layer 2 may not be able to completely block the gaps between all the anode plates 21 of the anode layer 2. In this case, the shielding traces 111 of other metal layers 11 can be designed according to the unshielded areas to form shielding traces 111, so that the unshielded areas are shielded by the shielding traces 111 of other metal layers 11, thereby protecting the thin film transistor 12.

[0065] Generally speaking, the wiring of different metal layers 11 has different functions. For example, two functional signal lines are provided in the first metal layer M1, and the two functional signal lines can be any two of the first direction reset signal line Vref-x, the scan signal line Vscan and the first direction power signal line Vdd-x. A functional signal line is provided in the second metal layer M2, and the functional signal line is a functional signal line other than the two functional signal lines in the first metal layer M1 among the first direction reset signal line Vref-x, the scan signal line Vscan and the first direction power signal line Vdd-x. The source electrode S and the drain electrode D are located in the third metal layer M3, and the signal connection wiring Vlink is located in the fourth metal layer M4. The data signal line Vdata, the second direction reset signal line Vref-y and the second direction power signal line Vdd-y are provided together in the fifth metal layer M5.

[0066] In this embodiment, the first metal layer M1, the second metal layer M2, the third metal layer M3 and the fourth metal layer M4 are sequentially arranged in a direction away from the substrate 13, and the distance between the fifth metal layer M5 and the anode layer 2 is the same as the distance between the fourth metal layer M4 and the anode layer 2. Since the fourth metal layer M4 and the fifth metal layer M5 are closer to the anode layer 2, it is preferred that the wiring of M4 and M5 is used as the shielding wiring 111 to shield the gap of the anode plate 21, which has the best effect.

[0067] In this embodiment, the key thin film transistor 12 is arranged on the side of the anode plate 21 facing the substrate 13. It can be understood that directly using the anode plate 21 to shield the key thin film transistor 12 is the most effective way, so the switch transistor can be directly arranged between the anode plate 21 and the substrate 13. At this time, the gap around the anode plate 21 still needs to be shielded by the shielding wire 111 to prevent external light from irradiating the switch transistor obliquely or through multiple reflections.

[0068] like Figure 1 As shown, along the thickness direction of the display panel, the projection of the anode plate 21 on the substrate 13 covers at least a portion of the projection of the thin film transistor 12 on the substrate 13 .

[0069] Specifically, in order to ensure the normal operation of the thin film transistor 12, whether it is a driving transistor or a switching transistor, at least the active layer of the thin film transistor 12 needs to be blocked by the anode plate 21, that is, the projection of the anode plate 21 on the substrate 13 covers the projection of the active layer of the thin film transistor 12 on the substrate 13 to ensure that the carriers of the active layer will not be affected by light.

[0070] If the anode plate 21 can completely cover the key thin film transistor 12 , the effect is best and most of the external light can be blocked. At this time, the gaps between adjacent anode plates 21 are blocked by the shielding wiring 111 , ensuring the normal operation of the driving device 12 .

[0071] It is worth noting that in order to improve the user experience, the mobile phone needs to have the function of adjusting the brightness of the display panel according to the strength of the external light during use. Generally speaking, the photosensitive element is arranged on the back of the display panel, and the external light is incident from the front of the display panel. Therefore, in order to allow the external light to irradiate the photosensitive element through the photosensitive hole 3, the photosensitive hole 3 has light transmittance in the thickness direction of the display panel, and the external light needs to avoid the anode plate 21 and the shielding wiring 111 within the range of the photosensitive hole 3. Therefore, in the present embodiment, the display panel includes a photosensitive hole 3, and the projection of the photosensitive hole 3 along the thickness direction of the display panel is completely located in the gap between the two adjacent anode plates 21, and is located outside the area of ​​the shielding structure to ensure that the anode plate 21 and the shielding wiring 111 of the metal layer 11 will not block the ambient light incident from the photosensitive hole 3.

[0072] In some embodiments, the shielding trace 111 of the metal layer 11 may not be able to completely avoid the photosensitive hole 3. In this case, it is necessary to ensure that the projection of part of the photosensitive hole 3 along the thickness direction of the display panel is located within the gap between the two adjacent anode plates 21 and outside the shielding structure to ensure that at least part of the external light can pass through the photosensitive hole 3 and be received by the photosensitive element. At this time, the transmittance of the photosensitive hole 3 will be reduced, but it will not affect the function of adjusting the brightness of the display panel according to the intensity of the external light.

[0073] It is worth noting that the positions of the array substrate 1 corresponding to the photosensitive holes 3 can be made of transparent material or hollowed out to avoid them.

[0074] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
