Summary of the invention

[0042] Some embodiments of the present disclosure provide a display device 100, which may be, for example, a mobile phone, a tablet computer, a personal digital assistant (PDA), a car computer, a wearable display device, etc., such as a watch. The embodiments of the present disclosure do not impose any special restrictions on the specific form of the display device 100.

[0043] In some embodiments, the display device 100 is an OLED display device 100. For example, the display device 100 is a flexible OLED display device 100, which can be used as a wearable display device. Figure 1A and Figure 1BThe structure diagrams of two wearable display devices (such as watches) are shown. The display screens of the wearable display devices have narrow borders, a high screen-to-body ratio, and good display effects.

[0044] like Figure 1A , Figure 1B and Figure 2 As shown, the display device 100 provided by some embodiments of the present disclosure includes a display panel 10, which has a display area AA and a peripheral area BB surrounding the display area AA, the peripheral area BB includes a first sub-peripheral area BB1 located on one side of the display area AA, and a second sub-peripheral area BB2 located on the other three sides of the display area AA.

[0045] like Figure 2 to Figure 5 As shown, the display panel 10 includes: a power bus 11 arranged in the peripheral area BB, a power surrounding line 12, at least two power connection lines 13, a plurality of data selectors 3 and a plurality of fan-out lines 2.

[0046] The power bus 11 is arranged in the first sub-peripheral area BB1, and the power wrapping line 12 is arranged in the peripheral area BB. For example, the power wrapping line 12 surrounds the display area AA. The power wrapping line 12 includes a sub-wrapping line 12a located in the first sub-peripheral area BB1. The sub-wrapping line 12a is close to the display area AA relative to the power bus 11. The power wrapping line 12 also includes other parts 12b except the sub-wrapping line 12a. The other parts 12b are located in the second sub-peripheral area BB2. The power wrapping line 12 is configured to transmit the received voltage signal to the display area AA.

[0047] At least two power connection lines 13 are arranged between the power wrapping line 12 and the power bus 11. One end of each power connection line 13 is electrically connected to the sub-wrapping line 12a, and the other end is electrically connected to the power bus 11. The power connection line 13 is configured to connect the power bus 11 and the sub-wrapping line 12a to transmit the voltage signal from the power bus 11 to the power wrapping line 12. At least two power connection lines 13 are divided into two groups and are respectively located on both sides of the dividing line L of the display panel 10 that is perpendicular to the first direction X1. The first direction X1 is the extension direction of the edge of the display panel 10 where the first sub-peripheral area BB1 is located; the second direction X2 is perpendicular to the first direction X1, and the edge of the display panel 10 refers to the outer contour line of the display panel 10.

[0048] The dividing line L divides the display panel 10 into two parts, left and right. In some examples, such as Figure 3 As shown, the dividing line L is the center line of the display panel, which divides the display panel into two equal parts. In other examples, the dividing line L can be left or right relative to the center line of the display panel 10, thereby dividing the display panel into two parts of unequal areas.

[0049] A plurality of data selectors 3 are arranged between the sub-circuit wire 12a and the power bus 11, and the plurality of data selectors 3 are divided into two groups and are respectively located on both sides of the dividing line L; each group of data selectors 3 includes at least two data selectors 3, and the at least two data selectors 3 are arranged in a row. In a group of power connection wires 13 and a group of data selectors 3 located on the same side of the dividing line L, the power connection wires 13 pass through the gaps between adjacent data selectors 3 to connect the sub-circuit wire 12a and the power bus 11.

[0050] Exemplarily, except for the data selectors 3 on both sides of the power connection line 13, the gap between two adjacent data selectors 3 in each group of data selectors 3 is very small, so that each group of data selectors 3 is more compact and the area occupied by them is reduced.

[0051] A plurality of fan-out wirings 2 are arranged between the edge of the display area AA close to the first sub-peripheral area BB1 and the plurality of data selectors 3; the plurality of fan-out wirings 2 are divided into two groups and are respectively located on both sides of the dividing line L; each data selector 3 is electrically connected to at least one fan-out wiring 2. The plurality of fan-out wirings 2 are configured to connect the plurality of data selectors 3 and the display area AA to realize signal transmission.

[0052] Exemplarily, each data selector 3 is electrically connected to 5 to 8 fan-out traces 2, for example, Figure 5 As shown, each data selector 3 is electrically connected to six fan-out wirings 2 .

[0053] In some implementations, when the dividing line L is the center line of the display panel, each group of fan-out lines 2 includes an equal number of fan-out lines, and each group of data selectors 3 includes an equal number of data selectors.

[0054] In the case where the dividing line L is biased to the left or right relative to the center line of the display panel 10, the number of fan-out routing lines included in each group of fan-out routing lines 2 and the number of data selectors 3 included in each group of data selectors 3 are set accordingly with the position of the dividing line L. For example. In the case where the dividing line L is biased to the left relative to the center line of the display panel 10, the number of fan-out routing lines included in a group of fan-out routing lines 2 located on the left side of the dividing line L is less than the number of fan-out routing lines 2 included in a group of fan-out routing lines 2 located on the right side of the dividing line L, and the number of data selectors 3 included in a group of data selectors 3 located on the left side of the dividing line L is less than the number of data selectors 3 included in a group of data selectors 3 located on the right side of the dividing line L. When the dividing line L is biased to the right relative to the center line of the display panel 10, the number of fan-out routings included in a group of fan-out routings 2 located on the left side of the dividing line L is greater than the number of fan-out routings 2 included in a group of fan-out routings 2 located on the right side of the dividing line L, and the number of data selectors 3 included in a group of data selectors 3 located on the left side of the dividing line L is greater than the number of data selectors 3 included in a group of data selectors 3 located on the right side of the dividing line L.

[0055] In some embodiments, the display panel 10 further includes a plurality of sub-pixels, a plurality of data lines, a plurality of gate lines, and a plurality of power sub-lines 14 disposed in the display area AA. Exemplarily, the plurality of sub-pixels are arranged in an array, and the sub-pixels arranged in a row along the first direction X1 are called a row of sub-pixels, and the sub-pixels arranged in a column along the second direction X2 are called a column of sub-pixels. The plurality of data lines extend along the second direction X2, and the plurality of gate lines extend along the first direction X1. A row of sub-pixels can be connected to a gate line, and a column of sub-pixels can be connected to a data line. In some examples, the plurality of fan-out routing lines 2 are connected to the plurality of data lines in a one-to-one correspondence, so that one fan-out routing line 2 corresponds to a column of sub-pixels. Figure 2 As shown, the multiple power sub-lines 14 include a power sub-line 14 extending along at least one first direction X1 and at least one power sub-line 14 extending along the second direction X2, and the multiple power sub-lines 14 are in a mesh shape. The multiple power sub-lines 14 are electrically connected to the power wrapping line 12 and are configured to transmit the voltage signal from the power wrapping line 12 to multiple sub-pixels in the display area AA.

[0056] In the above display panel 10, at least two power connection lines 13 are arranged between the power loop line 12 and the power bus 11, and at least two power connection lines 13 are divided into two groups and are respectively located on both sides of the dividing line L of the display panel 10 which is perpendicular to the first direction X1. Figure 8-Figure 9In the related technology shown, the display panel 10 only includes one power connection line 13, and the power connection line 13 is located on the dividing line L of the display panel 10. The structural design of the display panel 10 shown in the figure can reduce the size of the area where the multiple fan-out lines 2 are located in the second direction X2, which is beneficial to the narrowing of the frame. At the same time, the use of this structural design can reduce the signal strength difference of the voltage signal received by the sub-surround line 12a in the first direction X1, thereby improving the uniformity of the display brightness of the display area AA along the first direction X1.

[0057] The display panel 10 provided in some embodiments of the present disclosure is more advantageous than the display panel 10 in the related art in terms of the reasons for narrowing the frame as follows: Figure 8-Figure 9 As shown, in some embodiments, the display panel 10 in the related art includes only one power connection line 13, and the power connection line 13 is located on the dividing line L of the display panel 10. For example, the power connection line 13 is set in the middle of the area between the power loop line 12 and the power bus 11, and the position is between the two groups of data selectors 3. In this way, the power connection line 13 occupies a part of the space between the two groups of data selectors 3, thereby increasing the spacing between the two groups of data selectors 3 along the first direction X1. The multiple sub-pixels in the display area AA are divided into two parts along the dividing line L. The sub-pixels in the left and right parts correspond to two groups of data selectors 3 and two groups of fan-out routing lines 2, respectively. The two groups of data selectors 3 are far away from the sub-pixel columns at the junction of the left and right parts of the sub-pixels (the sub-pixel columns corresponding to the position of the dividing line L), which causes the innermost fan-out routing line 2 in each group of fan-out routing lines 2 to have a larger inclination angle. The innermost fan-out routing line 2 refers to the fan-out routing line 2 connecting the sub-pixel column corresponding to the position of the dividing line L and the innermost data selector 3 in each group of data selectors 3. Usually, the wiring is reasonable, and multiple fan-out routing lines 2 are arranged in parallel with each other. Among them, the inclination angle of the fan-out routing line 2 refers to the angle between the extension direction of the main part of the fan-out routing line 2 and the first direction X1, and the main part of the fan-out routing line 2 refers to the part of the fan-out routing line 2 that does not extend along the first direction X1 and the second direction X2.

[0058] The inventors of the present disclosure have verified and found that, when the number of the multiple fan-out routing lines 2 remains unchanged, the larger the inclination angle of the fan-out routing lines 2, the greater the space requirement in the second direction X2. Therefore, in the related technology, the area where the multiple fan-out routing lines 2 are located is larger in the second direction X2, and the multiple fan-out routing lines 2 need to occupy a larger space, thereby making the size of the first sub-peripheral area BB1 of the display panel 10 larger.

[0059] In this disclosure, Figure 2 to Figure 5As shown, since at least two power connection lines 13 are arranged between the power loop line 12 and the power bus 11, and at least two power connection lines 13 are divided into two groups and are respectively located on both sides of the dividing line L of the display panel 10 perpendicular to the first direction X1, the spacing between the two groups of data selectors 3 is not provided with a power connection line 13, so that the spacing between the two groups of data selectors 3 along the first direction X1 is reduced, and the distance between the two groups of data selectors 3 and the sub-pixels at the junction of the left and right parts of the sub-pixels (corresponding to the sub-pixel column at the position of the dividing line L) is closer, and the inclination angle of the innermost fan-out line 2 in each group of fan-out lines 2 is greatly reduced. When the number of fan-out lines 2 remains unchanged, the size of the area where the multiple fan-out lines 2 are located in the second direction X2 is also reduced accordingly, and the size of the first sub-peripheral area BB1 in the second direction X2 can be reduced, which is beneficial to the narrowing of the frame of the display panel 10.

[0060] The display panel 10 provided in some embodiments of the present disclosure can improve the uniformity of display brightness in the display area AA along the first direction X1 compared to the display panel 10 in the related art for the following reasons: In the related art, Figure 8 to Figure 10 As shown, the voltage signal transmitted by the power bus 11 is introduced into the middle position of the sub-circuit 12a through a power connection line 13, and then the voltage signal is transmitted to the power circuit 12 from the left and right directions, and then provided to each sub-pixel through the power sub-line 14. In this way, due to the voltage drop problem in the power circuit 12, the difference in the strength of the voltage signal received on the sub-circuit 12a of the power circuit 12 is relatively large. For example, the voltage signal strength at the middle position of the sub-circuit 12a is relatively strong, and the voltage signal strength at the two side positions is relatively weak. Therefore, along the first direction X1, the strength of the voltage signal received by multiple sub-pixels gradually decays from the middle to the two sides, affecting the uniformity of the display brightness of the display area AA.

[0061] like Figure 3 As shown, in the present disclosure, the voltage signal transmitted by the power bus 11 is introduced into the power loop line 12 from at least two positions through at least two power connection lines 13. In this way, compared with the related art, the difference in the intensity of the voltage signal received on the sub-loop line 12a of the power loop line 12 is reduced, thereby reducing the difference in the intensity of the voltage signal along the first direction X1, so that the intensity of the voltage signal received by multiple sub-pixels is more uniform, thereby improving the uniformity of the display brightness of the display area AA.

[0062] In some embodiments, the display panel 10 includes at least two power connection lines 13 , and the plurality of power connection lines 13 are divided into two groups, and the number of power connection lines 13 included in each group of power connection lines 13 ranges from 1 to 4.

[0063] In the case where each group of power connection lines 13 includes at least two power connection lines 13, there is at least one data selector 3 between two adjacent power connection lines 13, and the at least two power connection lines 13 are evenly distributed along the first direction X1 to further reduce the difference in the strength of the voltage signal received on the sub-surrounding line 12a along the first direction X1, which is conducive to improving the display effect. At the same time, among the multiple data selectors 3 in each group, the number of at least one data selector 3 between two adjacent power connection lines 13 is equal, for example, the number of at least one data selector 3 between two adjacent power connection lines 13 is 5.

[0064] In some embodiments, Figure 3 As shown, the dividing line L is the center line of the display panel 10, the number of power connection lines 13 included in each group of power connection lines 13 is equal, and the power connection lines 13 included in the two groups of power connection lines 13 are symmetrically arranged relative to the dividing line L. For example, the display panel 10 includes two power connection lines 13, and the two power connection lines 13 are divided into two groups and are respectively located on both sides of the dividing line L, and the two power connection lines 13 are symmetrically arranged relative to the dividing line L, and each power connection line 13 is at an equal distance from the dividing line L.

[0065] like Figure 3 As shown, the number of data selectors 3 included in each group of data selectors 3 is equal, and the data selectors 3 included in the two groups of data selectors 3 are symmetrically arranged relative to the dividing line L. For example, the display panel 10 includes a plurality of data selectors 3, and the plurality of data selectors 3 are equally divided into two groups, and the two groups of data selectors 3 are symmetrically arranged relative to the dividing line L, and the number of data selectors 3 between each power connection line 13 and the dividing line L is equal.

[0066] like Figure 3 As shown, the plurality of fan-out wirings 2 are equally divided into two groups and are respectively located on both sides of the dividing line L, and the two groups of fan-out wirings 2 are symmetrically arranged relative to the dividing line L.

[0067] In some embodiments, Figure 3 and Figure 4 As shown, the display panel 10 further includes: a plurality of electrostatic discharge protection circuits 4 disposed between the two groups of data selectors 3. The electrostatic discharge protection circuits 4 are configured to provide electrostatic protection for the circuit structure in the display panel 10, and discharge or balance high-voltage static electricity. Exemplarily, the plurality of electrostatic discharge protection circuits 4 are arranged in a row along the first direction X1.

[0068] Among them, along the first direction X1, the gap width between two adjacent electrostatic discharge protection circuits 4, and the gap width between the electrostatic discharge protection circuit 4 and the data selector 3 closest to each other are less than or equal to the width of the power connection line 13. The width of the power connection line 13 refers to the size of each power connection line 13 in the first direction X1. For example, Figure 4 As shown, the width d2 of the power connection line 13 is 180 μm to 220 μm, for example, the width d2 of the power connection line 13 is 200 μm.

[0069] like Figure 8 and Fig. 9 As shown, in the related art, since a power connection line 13 is provided at the position of the dividing line L of the first sub-peripheral area BB1, and multiple electrostatic discharge protection circuits 4 are provided on both sides of the power connection line 13, the area between the two groups of data selectors 3 occupied by the multiple electrostatic discharge protection circuits 4 and the power connection line 13 is larger, which makes the distance between the two groups of data selectors 3 larger, thereby increasing the size of the area where the multiple fan-out wirings 2 are located in the second direction X2. In the present disclosure, as Figure 4 As shown, along the first direction X1, the power connection line 13 cannot be set between two adjacent electrostatic discharge protection circuits 4, and between the electrostatic discharge protection circuit 4 and the data selector 3 that are closest to each other, that is, there is no space left between the two groups of data selectors 3 for setting the power connection line 13, so that the multiple electrostatic discharge protection circuits 4 and the multiple data selectors 3 are arranged more compactly, and the spacing between the two groups of data selectors 3 along the first direction X1 can reduce the size of the area where the multiple fan-out wirings 2 are located in the second direction X2, which is beneficial to the narrowing of the frame of the display panel 10.

[0070] In some examples, along the first direction X1 , the interval d1 between the two groups of data selectors 3 ranges from 600 μm to 700 μm. For example, along the first direction X1 , the interval d1 between the two groups of data selectors 3 ranges from 650 μm.

[0071] In some embodiments, Figure 7 As shown, each fan-out wiring 2 includes a wiring body 21 , and the angle between at least one wiring body 21 and the first direction X1 is an acute angle.

[0072] The fan-out routing 2 belonging to the same group is divided into a first part of fan-out routing 2A, a second part of fan-out routing 2B and a third part of fan-out routing 2C. The second part of fan-out routing 2B is located between the first part of fan-out routing 2A and the second part of fan-out routing 2C. The first part of fan-out routing 2A and the third part of fan-out routing 2C both include multiple adjacent fan-out routings 2. The second part of fan-out routing 2B includes at least one fan-out routing 2. The routing bodies 21 of the fan-out routing 2 included in each part of the fan-out routing 2 are parallel to each other.

[0073] An angle θ2 formed by the routing body 21 of the multiple fan-out routings 2 included in the first part of the fan-out routing 2A and the first direction X1 is an acute angle, an angle θ3 formed by the routing body 21 of the multiple fan-out routings 2 included in the third part of the fan-out routing 2C and the first direction X1 is an acute angle, and an extension direction (third direction X3) of the routing body 21 of the first part of the fan-out routing 2A intersects with an extension direction (fourth direction X4) of the third part of the fan-out routing 2C.

[0074] like Figure 3 As shown, in the first direction X1, the total size of each group of data selectors 3 is smaller than the total size of multiple pixel columns in the display area AA to which the group of data selectors 3 is connected, and along the second direction X2, each group of fan-out routing lines 2 presents a shape that gradually converges from the display area AA toward the multiple data selectors 3, so the routing body 21 of at least one fan-out routing line 2 is inclined, and the angle between the routing body 21 and the first direction X1 is an acute angle.

[0075] The fan-out routing lines 2 belonging to the same group are divided into a first part of fan-out routing lines 2A, a second part of fan-out routing lines 2B and a third part of fan-out routing lines 2C from left to right. The extension direction of the routing body 21 of the first part of fan-out routing lines 2A is the third direction X3, and the extension direction of the routing body 21 of the third part of fan-out routing lines 2C is the fourth direction X4, so that each group of fan-out routing lines 2 is overall gathered inward.

[0076] The second portion of fan-out routing 2B includes a fan-out routing 2, and a routing body 21 of the fan-out routing 2 extends along the second direction X2. For example, the entire fan-out routing 2 included in the second portion of fan-out routing 2B extends along the second direction X2.

[0077] In some examples, the angle θ2 formed between the routing body 21 of the first partial fan-out routing 2A and the first direction X1 is in the range of 30° to 45°.

[0078] The angle θ3 formed between the wiring body 21 of the second fan-out wiring 2B and the first direction X1 is in the range of 30° to 45°.

[0079] like Figure 7 As shown, when the first part fan-out routing 2 and the second part fan-out routing 2 are symmetrically arranged relative to a fan-out routing 2 included in the third part, the angle θ2 formed by the routing body 21 of the first part fan-out routing 2 and the first direction X1 is equal to the angle θ3 formed by the routing body 21 of the second part fan-out routing 2 and the first direction X1, for example, both are 40°.

[0080] In some embodiments, Figure 7As shown, each of the first and second fan-out routing lines 2 further includes: a first connecting section 22 and a second connecting section 23 respectively located at two ends of the routing body 21 .

[0081] One end of the first connection segment 22 is electrically connected to the wiring body 21, and the other end is electrically connected to the signal line in the display area AA. For example, the other end of the first connection segment 22 is electrically connected to the data line in the display area AA. One end of the second connection segment 23 is electrically connected to the wiring body 21, and the other end is electrically connected to the corresponding data selector 3. The first connection segment 22 and the second connection segment 23 both extend along the second direction X2.

[0082] As a possible design, Figure 7 As shown, in each group of fan-out routing lines 2, the first part of the fan-out routing lines 2A and the second part of the fan-out routing lines 2B are symmetrically arranged relative to a fan-out routing line 2 included in the third part, the spacing between the routing bodies 21 of two adjacent fan-out routing lines 2 is equal, and the spacing d7 between the first connecting sections 22 of two adjacent fan-out routing lines 2 is greater than the spacing d6 between the second connecting sections 23 of two adjacent fan-out routing lines 2, so that the fan-out routing lines 2 are gathered inward as a whole and the arrangement is more regular.

[0083] In some embodiments, Figure 5 As shown, the size d5 of the area where the plurality of fan-out traces 2 are located along the second direction X2 ranges from 200 μm to 250 μm, wherein the second direction X2 is perpendicular to the first direction X1. For example, the size d5 of the area where the plurality of fan-out traces 2 are located along the second direction X2 is 242.45 μm.

[0084] The inventor of the present disclosure has verified that when the display area AA is provided with 564 columns of pixels, that is, the display area AA is provided with 1692 columns of sub-pixels, the number of the plurality of fan-out lines 2 is 1692. Figure 8 to Figure 10 In the structural design of the power connection line 13 and the data selector 3 in the related art shown in FIG, the size d5 of the area where the plurality of fan-out lines 2 are located along the second direction X2 is 317.45 μm, and the Figure 5 In the structural design of the power connection line 13 and the data selector 3 provided in some embodiments of the present disclosure shown, the dimension d5 of the area where the multiple fan-out lines 2 are located along the second direction X2 is 242.45 μm, so that the dimension of the area where the multiple fan-out lines 2 are located along the second direction X2 is smaller, which is beneficial to narrowing the frame of the display panel 10.

[0085] In some embodiments, Figure 6 As shown, the orthographic projection of the power connection line 13 on the display surface of the display panel 10 at least partially overlaps with the orthographic projection of at least one fan-out line 2 on the display surface of the display panel 10 .

[0086] In some embodiments, Figure 6 As shown, the sub-winding line 12 a of the power winding line 12 extends along the first direction X1 , and the orthographic projection of the sub-winding line 12 a on the display surface of the display panel 10 at least partially overlaps with the orthographic projection of the plurality of fan-out traces 2 on the display surface of the display panel 10 .

[0087] The film layer where the multiple fan-out routing lines 2 are located is located on the side of the film layer where the power connection line 13 and the power wrapping line 12 are located, which is away from the display surface of the display panel 10, that is, the multiple fan-out routing lines 2 and the power connection line 13 are arranged in different layers, so that the multiple fan-out routing lines 2 do not need to avoid the power connection line 13, even if the power connection line 13 is changed from the position of the dividing line L to the positions on both sides of the dividing line L, the arrangement of the multiple fan-out routing lines 2 will not be affected by the position of the power connection line 13.

[0088] In some embodiments, the position of the power connection line 13 is related to the distribution of the data selectors 3. Among a group of power connection lines 13 and a group of data selectors 3 located on the same side of the dividing line L, the number of data selectors 3 between the power connection line 13 closest to the dividing line L and the dividing line L accounts for a total number of data selectors 3 in the group in a ratio ranging from 1:6 to 1:5.

[0089] For example, when the display panel 10 includes two power connection lines 13, there is a power connection line 13 and a group of data selectors 3 on both sides of the dividing line L, wherein a group of data selectors 3 located on the left side of the dividing line L includes 47 data selectors 3, and the number of data selectors 3 between the power connection line 13 and the dividing line L is 9.

[0090] In some embodiments, Figure 2 As shown, the first sub-peripheral area BB1 of the display panel 10 includes not only an area for setting a power bus 11, a power connection line 13, a sub-surround line 12a, a plurality of fan-out wirings 2 and a plurality of data selectors 3, but also a bending area and a bonding area. The dimensions of the bending area BB11 and the binding area BB12 along the first direction X1 are smaller than the dimensions of the main part of the display panel 10 along the first direction X1. The bending area BB11 and the binding area BB12 are inwardly retracted. The bending area BB11 is located on the side of the power bus 11 away from the display area AA, and the binding area BB12 is located on the side of the bending area BB11 away from the display area AA.

[0091] The display panel 10 further includes a plurality of second fan-out wirings 5 ​​and a plurality of binding electrodes 6, wherein the plurality of second fan-out wirings 5 ​​connect the plurality of data selectors 3 and the plurality of binding electrodes 6, the plurality of binding electrodes 6 are located in the binding area BB12, and the plurality of binding electrodes 6 are configured to bind a driving chip, for example, the driving chip includes a source driver. The source driver is configured to output a data signal, which is transmitted to the plurality of sub-pixels in the display area AA after being selected by the plurality of data selectors 3, so as to control the display panel 10 to display.

[0092] In some embodiments, the display panel 10 is bent to the back of the display panel 10 at the bending area BB11, so that the driving chip is disposed on the back of the display panel 10, further reducing the frame size of the display panel 10. In some examples, in the first sub-peripheral area BB1 of the display panel 10, along the second direction X2, the distance between the display area AA and the bending area BB11 ranges from 1000 μm to 1300 μm, for example, the distance between the display area AA and the bending area BB11 is 1100 μm.

[0093] The display device 100 provided in some embodiments of the present disclosure includes the above-mentioned display panel 10. Since the display panel 10 adopts a design in which at least two power connection lines 13 are distributed on both sides of the dividing line L of the display panel 10, the size of the plurality of fan-out lines 2 along the second direction X2 can be reduced, thereby reducing the size of the peripheral area of ​​the display panel 10. Therefore, the display panel 10 provided in some embodiments of the present disclosure has a narrower frame, thereby increasing the screen-to-body ratio and further improving the display effect.

[0094] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be thought of by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
