Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly, to an array substrate and a display device thereof. Background Art

[0002] With the development of liquid crystal display technologies, people increasingly pursue high contrast ratio, high transmittance, and high resolution of liquid crystal display devices. However, due to the blocking of the light source from the backlight by the metal film layer in the liquid crystal display panel, it is very difficult to improve the transmittance of the liquid crystal display panel. In current technologies, in order to make the display panel achieve high transmittance, the width of the metal electrode is usually continuously compressed to increase the passing area of the light source. However, when the width of the metal electrode is designed to be narrow, the metal electrode is easily broken during process fluctuations, resulting in dark spots or dark lines in the liquid crystal display panel during display, which affects the display effect. Summary of the Invention

[0003] In view of this, the present invention provides an array substrate and a display panel thereof to solve the problem of disconnection of the metal electrode.

[0004] The present invention provides an array substrate, including an array substrate, characterized in that the array substrate includes a plurality of data lines and scan lines, the data lines and the scan lines are arranged crosswise to define a plurality of sub-pixels arranged in an array, and each sub-pixel includes a strip-shaped electrode and a thin-film transistor; the strip-shaped electrode includes a plurality of strip-shaped branches and a connecting portion; the strip-shaped branches include a first type of strip-shaped branch and a second type of strip-shaped branch, the first type of strip-shaped branch and the second type of strip-shaped branch are arranged along a first direction and extend along a second direction, the width of the first type of strip-shaped branch is greater than the width of the second type of strip-shaped branch, and at least one second type of strip-shaped branch is connected to at least one adjacent second type of strip-shaped branch or at least one first type of strip-shaped branch through the connecting portion.

[0005] Based on the same inventive concept, the present invention further provides a display panel including the array substrate of the present invention.

[0006] Compared with the prior art, the display module and the display device provided by the present invention achieve at least the following beneficial effects:

[0007] An array substrate provided by the present invention is characterized in that the array substrate includes a plurality of data lines and scan lines. The data lines and scan lines are arranged in a crosswise manner to define a plurality of sub-pixels arranged in an array. Each sub-pixel includes a strip-shaped electrode and a thin-film transistor. The strip-shaped electrode includes a plurality of strip-shaped branches and a connecting portion. The strip-shaped branches include a first type of strip-shaped branch and a second type of strip-shaped branch. The first type of strip-shaped branch and the second type of strip-shaped branch are arranged in a first direction and extend in a second direction. The width of the first type of strip-shaped branch is greater than the width of the second type of strip-shaped branch. At least one second type of strip-shaped branch is connected to at least one adjacent second type of strip-shaped branch or at least one first type of strip-shaped branch through the connecting portion. In the present invention, by connecting the thinner second type of strip-shaped branch to its adjacent strip-shaped branch through the connecting portion to form a closed loop, even when the second type of strip-shaped branch is broken, the thinner second type of strip-shaped branch can still control the rotation of liquid crystal molecules through its adjacent strip-shaped branch, making the electric field of the array substrate complete, and solving the problem that there are dark spots or dark lines in the display panel during display due to the breakage of the thinner second type of strip-shaped branch.

[0008] Of course, it is not necessary for any product implementing the present invention to achieve all the above-described technical effects simultaneously.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] In the present specification, the embodiments are described in a progressive manner, and the key points of each embodiment are the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and the relevant parts can be referred to the description of the method part.

[0023] Figure 1 A schematic structural diagram of an array substrate provided by the present invention, Figure 2 A schematic structural diagram of a strip electrode provided by the present invention; An array substrate 100 provided by the present invention is characterized in that the array substrate 100 includes a plurality of data lines 1 and scan lines 2, and the data lines 1 and scan lines 2 are arranged in a cross pattern to define a plurality of sub-pixels 5 arranged in an array. The sub-pixels 5 include strip electrodes 4 and thin film transistors 10; the strip electrodes 4 include a plurality of strip branches 41 and a connecting portion 42; the strip branches 41 include a first type of strip branch 411 and a second type of strip branch 412. The first type of strip branch 411 and the second type of strip branch 412 are arranged along a first direction and extend along a second direction. The width of the first type of strip branch 411 is greater than the width of the second type of strip branch 412, and at least one second type of strip branch 412 is connected to at least one adjacent second type of strip branch 412 or at least one first type of strip branch 411 through the connecting portion 42.

[0024] Specifically, please continue to refer to Figure 1 and Figure 2, an array substrate 100 provided by the present invention is formed by intersecting a plurality of data lines 1 and a plurality of scan lines 2 to define a plurality of sub-pixels 5 arranged in an array. The sub-pixels 5 include strip electrodes 4 and thin film transistors 10. The strip electrodes 4 include a plurality of strip branches 41 and connecting portions 42; the strip branches 41 include first-type strip branches 411 and second-type strip branches 412. The width of the first-type strip branches 411 is greater than the width of the second-type strip branches 412, and at least one second-type strip branch 412 is connected to at least one adjacent second-type strip branch 412 through the connecting portion 42, or at least one second-type strip branch 412 is connected to the first-type strip branch 411 through the connecting portion 42; the first-type strip branches 411 and the second-type strip branches 412 are arranged along a first direction and extend along a second direction. Thus, by connecting the second-type strip branch 412 to an adjacent second-type strip branch 412 through the connecting portion 42, or connecting the second-type strip branch 412 to the first-type strip branch 411 through the connecting portion 42, a closed loop is formed. In this way, even if the thinner second-type strip branch 412 breaks due to process fluctuations, it can still be ensured that the thinner second-type strip branch 412 can still be controlled by an adjacent second-type strip branch 412 or the thicker first-type strip branch 411. When powered on, the deflection of the liquid crystal can still be controlled, so that the electric field of the array substrate 100 is complete, ensuring that there are no dark spots or dark lines in the liquid crystal display panel during display, and at the same time enabling the display panel to have a high transmittance.

[0025] Please continue to refer to Figure 1 and Figure 2 , in the array substrate 100 provided by the present invention, the strip electrode 4 is a pixel electrode. The pixel electrode includes a first end and a second end opposite to each other along the second direction. Each strip branch 41 at the first end is connected through the connecting portion 42, and at least one second-type strip branch 412 at the second end is connected to at least one adjacent second-type strip branch 412 or at least one first-type strip branch 411 through the connecting portion 42.

[0026] Specifically, please continue to refer to Figure 1 and Figure 2, the strip electrode 4 can be a pixel electrode. The pixel electrode includes a first end and a second end that are opposite to each other in the second direction. At the first end of the pixel electrode, each strip branch 41 is connected through a connecting portion 42, that is, the first end of the pixel electrode is in a closed state. At the second end of the pixel electrode, at least one second-type strip branch 412 is connected to an adjacent second-type strip branch 412 through a connecting portion 42, or at least one second-type strip branch 412 is connected to at least one first-type strip branch 411 through a connecting portion 42 at the second end of the pixel electrode. In this way, it not only ensures that the thinner second-type strip branches 412 form a closed loop with other pixel electrodes, solving the problem of breakage of the second-type strip branches 412, but also, since the second end of the pixel electrode is in an incompletely closed state, solves the problem of light source occlusion at the end of the pixel electrode, increases the light transmittance of the light source, and further improves the transmittance of the pixel electrode.

[0027] Further, please refer to Figure 3 (a)-(e), Figure 3 (a)-(e) is a schematic structural diagram of another strip electrode provided by the present invention; in the strip electrode 4 provided by the present invention, the strip electrode 4 can be a pixel electrode, and the middle of at least one second-type strip branch 412 is connected to the middle of at least one adjacent second-type strip branch 412 and / or the middle of at least one first-type strip branch 411 through a connecting portion 42.

[0028] Specifically, please continue to refer to Figure 3 (a)-(e). Under the condition that each strip branch 41 at the first end of the pixel electrode is connected through a connecting portion 42, there is still at least one middle part of a second-type strip branch 412 connected to the middle part of at least one adjacent second-type strip branch 412 through a connecting portion 42, or there is at least one middle part of a second-type strip branch 412 connected to the middle part of at least one first-type strip branch 411 through a connecting portion; or, in the pixel electrode, at least one middle part of a second-type strip branch 412 is connected to the middle part of at least one adjacent second-type strip branch 412 through a connecting portion 42, and at least one middle part of a second-type strip branch 412 is connected to the middle part of at least one first-type strip branch 411 through a connecting portion 42. In this way, by further connecting the middle parts of the thinner second-type strip branches 412 to the middle parts of the adjacent first-type strip branches 411 and / or second-type strip branches 412, multiple closed loops are formed, further reducing the possibility of breakage of the thinner second-type strip branches 412. Even if multiple thinner second-type strip branches 412 are broken, the broken second-type strip branches 412 can be controlled by their adjacent strip branches, ensuring the integrity of the electric field of the pixel electrode.

[0029] Figure 4 (a) is a schematic structural diagram of another strip-shaped electrode provided by the present invention; in the array substrate 100 provided by the present invention, the strip-shaped electrode 4 is a pixel electrode, and the strip-shaped electrodes 4 are connected through the connecting portion 42. The pixel electrode includes a first end and a second end opposite to each other in the second direction. At least one second-type strip-shaped branch 412 at least one of the first end and the second end is connected to at least one second-type strip-shaped branch 412 or at least one first-type strip-shaped branch 411 adjacent thereto through the connecting portion 42. The connecting portions 42 at the first end are arranged at intervals, and the connecting portions 42 at the second end are arranged at intervals.

[0030] In terms of having, please refer to Figure 4 (a), Figure 4 (a), the strip-shaped electrode 4 shown can be a pixel electrode. In a sub-pixel, the pixel electrode includes a first end and a second end opposite to each other in the second direction. The end of the pixel electrode away from the thin film transistor 10 is the first end, and the end of the pixel electrode away from the thin film transistor 10 is the second end. The strip-shaped electrodes 4 are connected through the connecting portion 42. The connecting portions 42 at the first end of the pixel electrode are arranged at intervals, and the connecting portions 42 at the second end of the pixel electrode are also arranged at intervals. For example, along the first direction, at Figure 4 (a), at the first end of the strip-shaped electrode 4 shown, no connecting portion 42 is provided between the first strip-shaped branch and the second strip-shaped branch, the second strip-shaped branch and the third strip-shaped branch are connected through the connecting portion 42, no connecting portion 42 is provided between the third strip-shaped branch and the fourth strip-shaped branch, and the fourth strip-shaped branch and the fifth strip-shaped branch are connected through the connecting portion 42; while at Figure 4 (a), at the second end of the strip-shaped electrode 4 shown, the first strip-shaped branch and the second strip-shaped branch are connected through the connecting portion 42, no connecting portion 42 is provided between the second strip-shaped branch and the third strip-shaped branch, the third strip-shaped branch and the fourth strip-shaped branch are connected through the connecting portion 42, and no connecting portion 42 is provided between the fourth strip-shaped branch and the fifth strip-shaped branch. It should be noted that in the first direction, the connecting portions 42 at the first end of the pixel electrode and the connecting portions 42 at the second end of the pixel electrode are arranged in a staggered manner, ensuring that the strip-shaped branches 41 can still be electrically connected together, thereby maintaining the electric field integrity between the strip-shaped branches 41. At the same time, it can also balance the electric field difference at both ends of the pixel electrode, which is beneficial to the uniformity of the image brightness. Thus, since both the first end and the second end of the pixel electrode are in a partially closed state, the non-connection portion 42 at the first end and the second end does not block the light source, increasing the light transmittance of the light source and further improving the transmittance of the pixel electrode.

[0031] Furthermore, please refer to Figure 5 (a), Figure 5Schematic diagram of another structure of the strip electrode provided by the present invention; in the array substrate 100 provided by the present invention, the middle parts of at least one second-type strip branch 412 are connected to the middle parts of at least one adjacent second-type strip branch 412 and / or the middle parts of at least one first-type strip branch 411 through a connecting part 42.

[0032] In terms of having, please continue to refer to Figure 5 (a), in the array substrate 100 provided by the present invention, the strip electrode 4 can be a pixel electrode. Both the first end and the second end of the pixel electrode are in a partially enclosed state. The connecting parts 42 at the first end of the pixel electrode are arranged at intervals, and the connecting parts 42 at the second end of the pixel electrode are also arranged at intervals. The middle parts of at least one second-type strip branch 412 are connected to the middle parts of at least one adjacent second-type strip branch 412 through the connecting part 42, or the middle parts of at least one second-type strip branch 412 are connected to the middle parts of at least one first-type strip branch 411 through the connecting part 42, or the middle part of at least one second-type strip electrode branch 412 is connected to the middle part of at least one adjacent second-type strip branch 412, and at the same time, there is a situation where the middle part of at least one second-type strip electrode branch 412 is connected to the middle part of at least one first-type strip electrode 411. In this way, even if multiple second-type strip branch electrodes 412 are broken, the current can still flow to the broken position through other branch electrodes 41 connected to the broken second-type strip branch electrodes 412, and the pixel electric field can still be kept intact, so as to ensure that the sub-pixel 5 is fully lit after being powered on.

[0033] Figure 6 (a) is a schematic diagram of another structure of the strip electrode provided by the present invention; in the array substrate 100 provided by the present invention, the strip electrode 4 is a pixel electrode. The pixel electrode includes a first end and a second end opposite to each other in the second direction. Each strip branch 41 at the first end is connected through a connecting part 42, and each strip branch 41 at the second end is not connected through a connecting part 42. The middle parts of at least one second-type strip branch 412 are connected to the middle parts of at least one adjacent second-type strip branch 412 and / or the middle parts of at least one first-type strip branch 411 through a connecting part 42.

[0034] Specifically, please continue to refer to Figure 6(a), in the array substrate 100 provided by the present invention, the strip-shaped electrode 4 can be a pixel electrode. At the first end of the pixel electrode, each strip-shaped branch 41 is connected through a connecting portion 42, that is, the first end of the pixel electrode is in a completely enclosed state. At the second end of the pixel electrode, each strip-shaped branch 41 is connected through a connecting portion 42, that is, the second end of the pixel electrode is in a completely unenclosed state. And the middle part of at least one second-type strip-shaped branch 412 is connected to the middle part of at least one adjacent second-type strip-shaped branch 412 through a connecting portion 42, or the middle part of at least one second-type strip-shaped branch 412 is connected to the middle part of at least one first-type strip-shaped branch 411 through a connecting portion 42, or the middle part of at least one second-type strip-shaped electrode branch 412 is connected to the middle part of at least one adjacent second-type strip-shaped branch 412, and at the same time, there is a situation where the middle part of at least one second-type strip-shaped electrode branch 412 is connected to the middle part of at least one first-type strip-shaped electrode 411. Thus, since the second end of the pixel electrode is in a completely unenclosed state, there is no light shielding by the connecting portion 42 at the second end, greatly increasing the aperture ratio and transmittance of the pixel electrode.

[0035] Please continue to refer to Figure 4 (a), in the array substrate 100 provided by the present invention, at least one first-type strip-shaped branch 411 is connected to at least one adjacent first-type strip-shaped branch 411 through a connecting portion 42.

[0036] Specifically, as Figure 4 (a) shows, in the array substrate 100 provided by the present invention, there is also at least one first-type strip-shaped branch 411 in the strip-shaped electrode 4 connected to at least one adjacent first-type strip-shaped branch 411 in the strip through a connecting portion 42. Thus, electrical connection is maintained between the strip-shaped branches 41, ensuring that the strip-shaped electrode has a complete electric field.

[0037] Please continue to refer to Figure 1 , in the array substrate 100 provided by the present invention, in the first direction, the second-type strip-shaped branch 412 is located on the side close to the data line 1.

[0038] Specifically, in the array substrate 100 provided by the present invention, in the first direction, the strip-shaped branch 41 close to the data line 1 is the second-type strip-shaped branch 412. In the actual process of production, the width of the strip-shaped branches 41 on both sides in the first direction will be relatively thin. At the same time, since the line width of the strip-shaped branches 41 on both edges of the strip-shaped electrode 4 is narrow, it is easier to improve the transmittance at the edge of the strip-shaped electrode 4. Optionally, the middle part of the strip-shaped electrode 4 can also include the second-type strip-shaped branch 412, and the present invention does not limit this.

[0039] It should be noted that the strip-shaped branch 41 being a pixel electrode is only an example. Optionally, the strip-shaped branch 41 can also be a common electrode, and the present invention does not make specific limitations thereto.

[0040] Figure 7 FIG. 4 is a schematic structural diagram of another strip-shaped electrode provided by the present invention. In the array substrate 100 provided by the present invention, the strip-shaped branch 41 includes a first broken line portion 41a and a second broken line portion 41b, and the first broken line portion 41a intersects with the second broken line portion 41b.

[0041] Specifically, as Figure 7 shown, the strip-shaped electrode 4 extends in the second direction as a whole, but the extending directions of each strip-shaped branch 41 are different. Optionally, each strip-shaped branch 41 is composed of a first broken line portion 41a and a second broken line portion 41b with different extending directions. Each strip-shaped electrode 4 corresponds to a sub-pixel 5, that is, the strip-shaped electrode 4 has a dual-domain pixel structure. The dual-domain pixel structure improves the contrast of the display panel by optimizing the arrangement of liquid crystal molecules, especially showing better performance at an oblique viewing angle. At the same time, the dual-domain pixel divides the liquid crystal molecules into two different directions of arrangement, significantly improving the viewing angle characteristics, reducing the problems of color and brightness changing with the viewing angle, and in addition, can also improve the transmittance of the pixel.

[0042] Furthermore, please continue to refer to Figure 2 , in the array substrate 100 provided by the present invention, the strip-shaped branch includes a first broken line portion, a second broken line portion, a third broken line portion, and a fourth broken line portion, and the third broken line portion 41c, the first broken line portion 41a, the second broken line portion 41b, and the fourth broken line portion 41d intersect in sequence.

[0043] Specifically, as Figure 2 shown, third broken line portions 41c and fourth broken line portions 41d are further provided at both ends of the first broken line portion 41a and the second broken line portion 41b. Thus, due to the larger initial alignment angles of the third broken line portions 41c and the fourth broken line portions 41d, the electric field torque is increased, the response speed of the liquid crystal molecules is faster, and the situation of the liquid crystal molecules being disordered is reduced, which is beneficial to improving the problem of trace mura on the display panel. Trace mura means that after sliding the screen with a finger or other object, the liquid crystal molecules are disordered, resulting in inconsistent brightness with the un-scratched area, manifested as a macroscopic scratch, and the disorder will automatically return to the normal domain lines within a certain period of time.

[0044] It should be noted that in the array substrate 100 provided by the present invention, the strip-shaped electrode 4 can be linear, or can also be curved or broken-line shaped, and no limitation is made herein.

[0045] Figure 8A structural schematic diagram of another array substrate provided by the present invention; the array substrate 100 of the present invention also includes a contact hole 6, in the direction perpendicular to the array substrate 100, the contact hole 6 and the projection of the data line 1 at least partially overlap, and the length of the strip branch 41 close to the side of the contact hole 6 is less than the length of the strip branch 41 away from the side of the contact hole 6.

[0046] Specifically, if Figure 8 As shown, the array substrate 100 is also provided with a contact hole 6 for connecting signal lines located at different levels. Optionally, the contact hole 6 can be used to connect touch signal lines and common electrodes located at different layers. In this embodiment, the common electrode is reused as a touch electrode, and display and touch can be performed in time. The contact hole 6 ensures that the common electrode is electrically connected to the touch signal line so that the touch signal can be transmitted to the common electrode, thereby realizing the touch function. If the end of the strip branch 41 close to the contact hole side is too close to the contact hole 6, it is easy to cause a short circuit between the strip branch 41 and the contact hole 6. Therefore, the length of the strip branch 41 close to the contact hole 6 side is less than the length of the strip branch 41 away from the contact hole 6 side to avoid the contact hole.

[0047] Based on the same inventive concept, the present invention also provides an array substrate 100, which includes a plurality of data lines 1 and scan lines 2, and the data lines 1 and the scan lines 2 are cross-arranged to form a plurality of pixel units 5 arranged in an array, and the pixel unit 5 includes a strip electrode 4; the strip electrode 4 includes a plurality of strip branches 41 and a connecting portion 42, and the difference in width between each strip branch 41 is less than or equal to 0.2 microns, and at least one end of the strip electrode 4 is connected to the strip branch 41 by the connecting portion 42, and / or the middle part of some of the strip branches 41 is connected by the connecting portion 42.

[0048] Specifically, if Figures 1 - 8As shown, in the array substrate 100 provided by the present invention, the difference in width between each strip-shaped branch 41 can be set to be less than or equal to 0.2 micrometers, and at least one end of the strip-shaped electrode 4 has some strip-shaped branches 41 connected through the connecting portion 42, or some strip-shaped branches 41 in the middle of the strip-shaped electrode 4 are connected through the connecting portion, or at least one end of the strip-shaped electrode 4 has some strip-shaped branches 41 connected through the connecting portion 42, and some strip-shaped branches 41 in the middle are connected through the connecting portion. In the actual process of industrial production, due to process fluctuations or machine precision problems, there may be differences in the width of each strip-shaped branch 41. By providing the connecting portion 42, it can be ensured that the strip-shaped branches 41 with a narrower width will not break, and at the same time, it can also ensure that the product can withstand extremely strict high-temperature and high-humidity tests, reduce the risk of wire breakage, ensure that there are no dark spots or dark lines when the liquid crystal display panel is displaying, and at the same time make the display panel have a high transmittance. The array substrate 100 provided by the present invention also has the beneficial effects of the array substrate 100 in the above-mentioned embodiments, and the same points will not be elaborated here.

[0049] Optionally, as Figure 3 (f), Figure 4 (b), Figure 5 (b), Figure 6 (b) shows that the difference in width between each strip-shaped branch 41 is 0, that is, the widths of all strip-shaped branches 41 are equal, which is also within the protection scope of the present invention.

[0050] Figure 9 is a schematic structural diagram of another array substrate provided by the present invention; it should be noted that, as Figure 9 shown, the array substrate 100 provided by the present invention can include any one of the strip-shaped electrodes 4 in the above-mentioned embodiments, and can achieve the corresponding technical effects.

[0051] Based on the same inventive concept, the present invention also provides a display panel. Figure 10 is a cross-sectional schematic diagram of a display panel 200 provided by the present invention. The display panel 200 provided by the present invention includes the array substrate 100 in the above-mentioned embodiments. Specifically, the display panel 200 includes the array substrate 100, a CF substrate 7 opposite to the array substrate 100, a liquid crystal layer 8 located between the array substrate 100 and the CF substrate 7, and also includes a pixel electrode 4 and a common electrode 9 located on the array substrate 100. Under the energized condition, an electric field is generated between the pixel electrode 4 and the common electrode 9 to drive the liquid crystal molecules to deflect.

[0052] It should be noted that the common electrode 9 of the present invention can be located above the pixel electrode 4 or below the pixel electrode 4, and the present invention does not make a limitation.

[0053] It should be noted that the common electrode 9 of the present invention can be strip-shaped or block-shaped; the pixel electrode 4 can be strip-shaped or block-shaped, and the present invention does not make any limitations in this regard.

[0054] As can be seen from the above embodiments, the array substrate and the display panel provided by the present invention achieve at least the following beneficial effects:

[0055] An array substrate provided by the present invention is characterized in that the array substrate includes a plurality of data lines and scan lines. The data lines and the scan lines are arranged in a crosswise manner to define a plurality of sub-pixels arranged in an array. The sub-pixels include strip-shaped electrodes and thin-film transistors. The strip-shaped electrodes include a plurality of strip-shaped branches and connecting portions. The strip-shaped branches include a first type of strip-shaped branch and a second type of strip-shaped branch. The first type of strip-shaped branch and the second type of strip-shaped branch are arranged along a first direction and extend along a second direction. The width of the first type of strip-shaped branch is greater than the width of the second type of strip-shaped branch. At least one second type of strip-shaped branch is connected to at least one adjacent second type of strip-shaped branch or at least one first type of strip-shaped branch through a connecting portion. By connecting the thinner second type of strip-shaped branch to its adjacent strip-shaped branch through a connecting portion to form a closed loop, even when the second type of strip-shaped branch is broken, the thinner second type of strip-shaped branch can still control the rotation of liquid crystal molecules through its adjacent strip-shaped branch, so that the electric field of the array substrate is complete, and the problem of dark spots or dark lines existing in the display panel during display due to the breakage of the thinner second type of strip-shaped branch is solved.
