[0033] When fingerprint recognition is needed, there are various unlocking methods, such as fingerprint unlocking integrated with a HOME key, side fingerprint unlocking, back fingerprint, and with the popularity of full screens, under-screen fingerprint recognition has become a common unlocking method in high-end electronic devices.

[0034] In order to realize the function of this scene and similar scenes, the problem of screen transmittance needs to be considered, such as Figure 1 As shown in the figure, the hollowing of the wire for light transmission makes the wire unevenly support the pixel anode, so that Figure 1 For example, the upper part of the pixel anode collapses inwardly to the paper surface (as shown in cross section A-A) due to the large area without support, resulting in poor flatness of the entire pixel anode, and further causing the light emitting element corresponding to the pixel anode to emit light unevenly, which is manifested as serious color deviation of the display screen at a large viewing angle.

[0035] In order to alleviate this adverse phenomenon, with reference to Figure 2 The present application provides a display substrate 10, which is arranged with a plurality of pixel anodes 1011 and power supply wires 1012; the power supply wire 1012 is provided with a first opening 10121, the pixel anode 1011 is arranged on the first opening 10121 along the length direction of the power supply wire 1012, the diameter of the first opening 10121 along the width direction of the pixel anode 1011 is less than the width of the pixel anode 1011, so that the pixel anode 1011 is connected with the power supply wire 1012 across the first opening 10121, and the first opening 10121 can transmit light. The support effect is shown in cross section B-B.

[0036] It can be understood that, with reference to Figure 2 The length direction can be the direction in which different pixel anodes are arranged on the same power supply wire, and the width direction can be understood as the direction perpendicular to the length direction.

[0037] Through the above scheme, the first opening is arranged on the power supply wire, and the pixel anode with a slightly larger width is connected with the power supply wire across the first opening, so that the pixel anode across the first opening can be uniformly or approximately uniformly stressed in the width direction. Since the stress is optimized, the flatness of the pixel anode is optimized, and the problem of color deviation of the display panel at a large viewing angle caused by the flatness is alleviated.

[0038] It can be understood that, Figure 2 The shape of the first opening in the above is only exemplary, and the shape of the first opening can be any shape, and in the present application, when the first opening can support the pixel anode on both sides of the width direction of the power supply wire, so that the pixel anode is flat, it can be used in the present application. For example, the first opening can be rectangular, circular, elliptical, irregular polygon, regular polygon or curved figure.

[0039] In the present application, the power supply wire can be a metal material, a semiconductor material, a conductive polymer, a carbon material or any other conductive material.

[0040] In an embodiment of the present application, a metal material with small thermal deformation can be used to ensure high conductivity efficiency in a high temperature environment. This selection helps to reduce the impact of heat on the shape of the power supply wire, thereby ensuring that the thickness of the power supply wire changes little over time.

[0041] Selecting a metal material with high conductivity, such as copper or aluminum, helps to ensure fast transmission of current in the wire, improve conductivity efficiency, and reduce energy consumption.

[0042] Using a metal material with small thermal deformation can maintain good shape stability in a high temperature environment, reduce shape changes caused by thermal expansion, and help maintain the flatness of the power supply wire.

[0043] The power supply wire is a key component that supports the pixel anode, and its shape stability directly affects the quality of the display. By using a metal material with small thermal deformation, the shape of the power supply wire can be kept relatively stable over time, providing more uniform support.

[0044] Metal materials generally have good high temperature resistance, which is particularly important for some high-performance, high-load application scenarios, ensuring that the power supply wire remains stable and reliable under long-term high-load operation.

[0045] Selecting common metal materials can help control manufacturing costs while providing good conductivity and thermal stability, making the solution more feasible in practical applications.

[0046] For example, referring to Figure 3 , the display substrate 10 can also be arranged with data wires 1021, and the data wires 1021 and the power supply wires 1012 are located in different layers of the display substrate, and the data wires 1021 and the power supply wires 1012 have an overlapping area. The support effect of the power supply wire is shown in cross-section C-C.

[0047] It can be understood that the present application does not limit the layer of the data wire or the power supply wire. When the data wire and the power supply wire are not in contact in the thickness direction, they can be used in the embodiments of the present application.

[0048] Because there are data wires overlapping with the power supply wires in addition to the power supply wires, the electromagnetic field generated by the current carried by the power supply wires affects the nearby data wires when the display substrate is running, resulting in unwanted interference signals in the data wires. This crosstalk can cause the quality of data transmission to decrease and increase the error rate in data transmission.

[0049] By reducing the overlapping area, the mutual influence between the conductive lines can be reduced, the ratio between the signal and the noise can be improved, the signal-to-noise ratio can be improved, and the clarity and accuracy of the signal can be maintained.

[0050] Based on this, in the present application, the power supply conductive line can also be provided with a second opening or a U-shaped groove, and the second opening or the U-shaped groove is at least partially located in the overlapping area; the second opening is at least partially located outside the coverage range of the pixel anode and can transmit light.

[0051] By providing the power supply conductive line with the second opening or the U-shaped groove, since the second opening or the U-shaped groove is located in the overlapping area of the power supply conductive line and the data conductive line, the second opening or the U-shaped groove can reduce the size of the overlapping area, further reduce the electromagnetic field generated by the power supply conductive line at the overlapping position, and thus reduce the crosstalk to the data conductive line.

[0052] In an embodiment, referring to Figure 4a A second opening 10122 can be formed in the power supply conductive line. In another embodiment, referring to Figure 4b A U-shaped groove 10123 can be formed in the power supply conductive line. In another embodiment, the second opening 10122 and the U-shaped groove 10123 can be formed in the power supply conductive line at the same time.

[0053] In any embodiment of the present application, the U-shaped groove can refer to any one or more grooves with an open side in the power supply conductive line.

[0054] It can be understood that the number of the second opening and the U-shaped groove in the present application is not limited and can be determined according to the specific needs of the product.

[0055] On the basis of any embodiment of the present application, the display panel can adopt the LTPO (Low-Temperature Polycrystalline Oxide) technology. Compared with the conventional scheme, in the present application, the power supply conductive lines on both sides of the first opening are connected with the pixel anode, the contact area of the pixel anode and the power supply conductive line is increased, the equivalent capacitance of the pixel anode at the contact position is optimized, and the problem of rising of the dark state voltage of the LTPO is solved.

[0056] The decrease of the dark state voltage means that when the display does not display active content, the pixel can be turned off more effectively, thereby reducing the power consumption. At the same time, the deep black color can be realized more accurately, and the display contrast and image quality are improved.

[0057] In order to further increase the flatness of the pixel anode, referring to Figure 5Any shape of power supply wire 10124 can be added below the pixel anode to increase the support to the pixel anode, and further increase the flatness of the pixel anode. The dashed part in the figure represents the mounting position of the pixel anode, and any shape of power supply wire 10124 can increase the support to the pixel anode, and the X-shaped and the linear-shaped are only exemplary.

[0058] In an embodiment of the present application, referring to Figure 6 , the display substrate 10 can be arranged with an auxiliary power supply wire 1013, the auxiliary power supply wire 1013 is connected with the power supply wire 1012 across the first opening 10121, the auxiliary power supply wire 1013 is at least partially connected with the pixel anode 1011, the auxiliary power supply wire 1013 has the same thickness as the power supply wire 1012, and is parallel to the data wire 1021.

[0059] In the above scheme, the auxiliary power supply wire has the same thickness as the power supply wire, so that the support area is increased without causing uneven changes. At the same time, the auxiliary power supply wire is parallel to the data wire, so that the auxiliary power supply wire and the data wire do not have overlapping areas, and the crosstalk of the auxiliary power supply wire to the data wire can be reduced.

[0060] It can be understood that in an embodiment of the present application, the power supply wire and the auxiliary power supply wire and other power supply wires can be welded or pasted.

[0061] In another embodiment, the power supply wire can be integrally formed with the auxiliary power supply wire.

[0062] The integrally formed power supply wire and auxiliary wire do not have an interface, so that the power supply is more stable, and the case that the uneven thickness at the interface affects the display effect can be reduced.

[0063] The integrally formed power supply wire and auxiliary wire can be processed by laser cutting, stamping or etching and other technical means.

[0064] In an embodiment of the present application, the sizes of the pixel anodes corresponding to at least two different pixels are different.

[0065] It can be understood that the pixel anodes of different sizes can be connected to the same power supply wire (as shown in Figure 7a ), or can be connected to different power supply wires (as shown in Figure 7b ).

[0066] In an embodiment, the size of the pixel anode can be set according to the color of the pixel, the sizes of the pixel anodes corresponding to the pixels of the same color are the same, and the sizes of the pixel anodes corresponding to the pixels of different colors are different

[0067] In any of the above embodiments, the pixel anodes of different sizes are arranged on different types of power supply wires, so that the areas of the pixel anodes of different sizes through which light passes are equal.

[0068] It can be understood that the different types of power supply wires can be understood as one or more variables of the thickness, opening position / size / shape, slotting position / size / shape, whether auxiliary power supply wires, and the position / size / shape of the auxiliary power supply wires.

[0069] In this application, other schemes for changing the power supply wires can also be used, and schemes obtained without creative labor on the basis of the embodiments given in this application should fall within the protection scope of this application.

[0070] By using different power supply wires for the pixel anodes of different color pixels, the effect of equal light transmission area is obtained.

[0071] It can be understood that the area for transmitting light in this application can refer to the area that is not blocked by the pixel anode, the power supply wire, the auxiliary power supply wire, or the signal wire. Those skilled in the art can freely select the type of power supply wire that meets the actual product requirements according to the content of the embodiments given in this application.

[0072] In an embodiment, referring to Figure 8 , an exemplary pixel size is given, in which the size and shape of the pixel anodes R, G, and B corresponding to red pixels, green pixels, and blue pixels are different, and therefore the support modes of the power supply wires corresponding to the three different pixel anodes can not be the same to ensure uniform light incidence.

[0073] It can be understood that the above embodiments can be applied only to the pixel anodes in the area that needs to transmit light, and the power supply wires connected to pixel anodes of the same size in the area that does not need to install the optical sensing device can also be different.

[0074] Correspondingly, referring to Figure 9 , the application also provides a display panel 11, which can include the display substrate 10 in any of the above embodiments.

[0075] The embodiments and advantages of the display panel can refer to the foregoing part of the display substrate.

[0076] Correspondingly, referring to Figure 10 , the application also provides a display screen assembly 1, which can include the display panel 11 and the under-screen optical sensing device 12, and the under-screen sensing device 12 is used to receive light that transmits through the display panel 11.

[0077] In the present application, the under-screen sensing device can include one or more of the following:

[0078] The under-screen fingerprint identification device, the under-screen camera device, the under-screen ambient light sensing device, and the under-screen distance sensing device.

[0079] On this basis, the display screen assembly can also include other electronic device parts, such as touch devices, flexible flat cables, heat sinks, drive circuit boards, screen supports, etc., which are not specifically limited in the present application and are determined according to actual products.

[0080] Correspondingly, with reference to Figure 11 The present application also provides another display substrate 20, which can be arranged with a plurality of pixel anodes 2011 and power supply wires 2012; the power supply wire 2012 is provided with a U-shaped groove, the pixel anode is arranged on the U-shaped groove and contacts the power supply wire of the U-shaped groove, and the pixel anode is located in the middle of the U-shaped groove, and the U-shaped groove can transmit light. The hierarchical relationship of each part is shown in cross section D-D.

[0081] Since the U-shaped groove is provided on the power supply wire, the middle part of the U-shaped groove on the power supply wire, i.e. the position of the narrow part of the power supply wire, is the Figure 11 bottom part of the U-shaped groove. The pixel anode is located at this position, so that the parts of the pixel anode distributed on both sides of the middle part of the U-shaped groove are uniformly stressed, the flatness of the pixel anode is increased, and the color cast problem is alleviated.

[0082] In an embodiment, the position of the power supply wire of the U-shaped groove can coincide with the symmetry axis of the pixel anode to obtain a more uniform support effect.

[0083] In an embodiment, the display substrate can also be arranged with data wires, and the data wires and the power supply wires have an overlapping area.

[0084] Similarly, the existence of the overlapping area causes crosstalk of the power supply wire to the data wire.

[0085] In order to reduce this crosstalk, in an embodiment, the power supply wire can also be provided with a second U-shaped groove or an opening, and the second U-shaped groove or the opening is at least partially located in the overlapping area; the second U-shaped groove or the opening is at least partially located outside the coverage range of the pixel anode and can transmit light.

[0086] Since the second U-shaped groove and the opening are located in the overlapping area, when the second U-shaped groove and the opening are provided on the power supply wire, the size of the overlapping area can be reduced, the size of the magnetic field generated by the power supply wire at the overlapping position can be reduced, and the crosstalk of the power supply wire to the signal wire can be reduced.

[0087] In the above embodiment, the second U-shaped groove and the opening are located outside the coverage of the pixel anode, and thus are difficult to be blocked by the pixel anode, and can thus play a role of transmitting light.

[0088] In an example embodiment, with reference to Figure 12 An auxiliary power supply wire can also be added, and the shape and size of the auxiliary power supply wire can be selected as needed.

[0089] In another embodiment, as shown in Figure 12 The auxiliary power supply wire can also be combined with other elements to increase the uniform support effect on the pixel anode.

[0090] In an embodiment of the present application, the display panel can adopt the LTPO technology.

[0091] The middle part of the U-shaped groove increases the contact area of the pixel anode and the power supply wire compared with the conventional technical solution, thereby optimizing the equivalent capacitance, reducing the dark state voltage, and reducing the dark state voltage, which means that the display can more effectively turn off the pixels when it is in a non-active content state, thereby reducing energy consumption. In addition, this also helps to more accurately achieve deep black, improve display contrast and image quality.

[0092] In the present application, the sizes of the pixel anodes of pixels presenting different colors are different; therefore, in an embodiment, the pixel anodes of pixels presenting different colors are arranged on different types of power supply wires, and the areas through which light is transmitted at positions where the pixel anodes of pixels presenting different colors are located are equal.

[0093] In the above solution, the thickness of the auxiliary power supply wire is equal to that of the power supply wire, so that the support area is increased without causing uneven changes in the surface. At the same time, the auxiliary power supply wire is parallel to the data wire, so there is no overlapping area between the two, which helps to reduce the crosstalk of the auxiliary power supply wire to the data wire.

[0094] Correspondingly, with reference to Figure 13 The present application also provides a display panel 21, which can include the display substrate 20 in any of the embodiments.

[0095] Correspondingly, with reference to Figure 14 The present application also provides a display screen assembly 2, which can include the display panel 21 and the under-screen optical sensing device 22 described above, and the under-screen sensing device 22 is used to receive light transmitted through the display panel.

[0096] In the present application, the under-screen sensing device can include one or more of the following:

[0097] The under-screen fingerprint identification device, the under-screen camera device, the under-screen ambient light sensing device, and the under-screen distance sensing device.

[0098] On this basis, the display screen assembly can further include parts of other electronic devices, such as a touch device, a flexible flat cable, a heat sink, a driving circuit board, a screen support, etc., which are not specifically limited in the present application and are determined according to actual products.

[0099] The contents of the above embodiments are only exemplary, and a person skilled in the art can combine a plurality of embodiments according to actual needs. It can be understood that the beneficial effects and the contents of the embodiments of the same structure recorded in different parts can refer to the contents recorded in other parts.

[0100] As an exemplary combination, reference can be made to Figure 15 , in which different shapes of polygons are used to represent pixel anodes of pixels of different colors, and the vertically and horizontally interlaced wires are power supply wires and data wires. Specifically, each dotted oval circle is a unit, Figure 15 Four units are shown in the figure, each of which includes a pixel anode 2011a of a red pixel, two pixel anodes 2011b of green pixels, and a pixel anode 2011c of a blue pixel; wherein the pixel anode 2011a of the red pixel and the pixel anode 2011c of the blue pixel are located on the same power supply wire 2012a, and the pixel anode 2011b of the blue pixel is located on the power supply wire 2012b. As can be seen from the figure, 2012a and 2012b have different widths, and the U-shaped grooves corresponding to the pixel anode 2011a of the red pixel and the pixel anode 2011c of the blue pixel on the same power supply wire 2012a are also different to meet the light transmission requirements of pixel anodes of different sizes.

[0101] Although this specification contains many specific implementation details, these should not be construed as limiting the scope or the range of any invention, but merely as describing features that are specific to certain embodiments. Certain features that are described in the specification in the context of a number of embodiments also can be implemented in a single embodiment. Also, although the features can be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination and the claimed combination can then be directed to a subcombination or variation of a subcombination.
