[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0026] With the popularity of narrow-frame designs, cameras are usually installed inside display screens. In order to ensure that the photo-taking function is not affected, the data signal lines need to be wound around the camera openings, which results in the data signal lines around the openings being longer than those at non-opening locations, leading to inconsistent resistance on the data signal lines, resulting in uneven display (i.e., mura) problems. The mura phenomenon is more obvious especially at low grayscales.
[0027] The resistance on the data signal line is R=ρL / S, where ρ represents resistivity, which is related to the inherent properties of the selected metal and is a fixed value for a certain metal. L represents the length of the data signal line, and S represents the cross-sectional area of the data signal line. When the winding length of the data signal line around the opening increases, that is, L increases, the resistance of the data signal line can be kept consistent by increasing S. The inventors have found that since the camera is usually set close to the upper frame, the space of the upper frame is limited, and the data signal line cannot be widened to adjust the resistance on the data signal line; and there are various metal wirings on the display panel, and it is not easy to widen the data signal line locally. In addition, with the rapid development of display technology, foldable electronic devices have emerged. Typically, foldable electronic devices include a main screen and a sub-screen. The main screen and the sub-screen are two independent screens that require two flexible circuit boards to control separately.
[0028] In order to solve the above technical problems, in the first aspect, an embodiment of the present application provides a display panel, which has a first display area, a bending area, and a second display area arranged in sequence along a first direction, and the display panel includes: a plurality of data signal lines arranged along a second direction, the data signal lines extend from the first display area to the second display area along the first direction, and the first direction and the second direction intersect; an opening, located in the first display area or the second display area, the plurality of data signal lines include at least one first data signal line partially surrounding the opening and at least one second data signal line not surrounding the opening; along the second direction, at least part of the width of the first data signal line in the bending area is greater than the width of the second data signal line in the bending area. For example, the entire width of the first data signal line in the bending area is greater than the width of the second data signal line in the bending area, or the width of a part of the first data signal line in the bending area is greater than the width of the second data signal line in the bending area. Compared with the first display area and the second display area, the bending area has a larger idle space, so widening the first data signal line in the bending area is easy to operate and can make full use of the space in the bending area. In addition, the first data signal line and the second data signal line are obtained by depositing a metal layer and etching a patterning process, so the thickness of the first data signal line and the second data signal line are the same. The cross-sectional area of the first data signal line can be changed by adjusting the width of the first data signal line. After widening at least part of the first data signal line in the bending area, the resistance of the first data signal line and the resistance of the second data signal line can be made the same, improving or eliminating the problem of uneven display, especially mura at low grayscale. In addition, the first display area and the second display area belong to a screen and can be controlled by the same flexible circuit board, saving a flexible circuit board, reducing costs, and reducing the thickness of the display panel, which is suitable for preparing light and thin electronic devices.
[0029] Figure 1 FIG. 1 is a schematic diagram of the front structure of a display panel provided in an embodiment of the present application in an unbent state. Figure 1 As shown, the display panel has a first display area L1, a bending area L2 and a second display area L3 which are sequentially arranged along a first direction (ie, the y direction).
[0030] The display panel includes a plurality of data signal lines 100 arranged along a second direction (ie, x direction), and the data signal lines 100 extend from the first display area L1 to the second display area L3 along a first direction (ie, y direction), wherein the first non-direction intersects the second direction.
[0031] The display panel further includes an opening 200. Figure 1 In the embodiment, the opening 200 is located in the first display area L1 , and the plurality of data signal lines 100 include at least one first data signal line 110 partially surrounding the opening 200 and at least one second data signal line 120 not surrounding the opening 200 .
[0032] Along the second direction, the width of at least part of the first data signal line 110 in the bending area L2 is greater than the width of the second data signal line 120 in the bending area L2. Specifically, the first data signal line 110 includes a first segment 111 located in the bending area L2, and the width of the first segment 111 is greater than the width of the second data signal line 120 in the bending area L2. In other words, the widened portion of the first data signal line 110 in the bending area is defined as the first segment 111. Figure 1 In the embodiment, the widths of the first sections 111 of the first data signal lines 110 are the same, and the lengths of the first sections 111 of at least some of the first data signal lines 110 are different. Therefore, the resistance of different first data signal lines 110 can be adjusted by adjusting the length of the first section 111 (i.e., adjusting the length of the widened portion). Optionally, the length of the first section 111 is proportional to the winding length of the first data signal line 110. If the winding length of the first data signal line 110 is longer, the length of the first section 111 is longer. The closer the first data signal line 110 is to the opening, the longer the winding length, and accordingly, the longer the length of the first section 111, so that the resistances of different first data signal lines 110 can be ensured to be the same. In the embodiment of the present application, along the first direction, the widths of the first section 111 at different positions are equal, so that the manufacturing process can be simplified. In other embodiments, along the first direction, the width of the first segment 111 at different positions is different. For example, along the first direction, the width of the first segment 111 first widens and then thins to prevent the width of the first segment 111 from suddenly increasing, resulting in excessive local current and reducing the service life of the first data signal line 110.
[0033] Continue to refer Figure 1 , the width of at least a portion of the first data signal line 110 in the bending area (i.e., the first section 111) is greater than the width of the first data signal line 110 in the first display area L1 or the second display area L3. Preferably, the width of the first data signal line 110 in the first display area L1 is equal to the width of the first data signal line 110 in the second display area L3. That is, in the embodiment of the present application, only at least a portion of the first data signal line 110 in the bending area needs to be thickened, and the widths of the first data signal lines 110 in other areas are the same, which can simplify the manufacturing process and improve the uniformity of display.
[0034] In the embodiment of the present application, different second data signal lines 120 have the same width in the bending area L2. The width of the second data signal line 120 in the bending area L2 is equal to the width of the second data signal line 120 in the first display area L1 or the second display area L3, which can simplify the manufacturing process and improve the uniformity of the display. Optionally, the width of the first data signal line 110 in the first display area L1 is equal to the width of the second data signal line 120 in the first display area L1, and / or the width of the first data signal line 110 in the second display area L3 is equal to the width of the second data signal line 120 in the second display area L3, which can simplify the manufacturing process and improve the uniformity of the display.
[0035] Continue to refer Figure 1 The display panel further includes a flexible circuit board 300, which is located on a side of the first display area L1 away from the bending area L2, and the data signal line 100 is connected to the flexible circuit board 300. The flexible circuit board 300 or the driving chip on the flexible circuit board 300 outputs a driving signal to the data signal line 100 to drive the display panel to emit light. In some embodiments, in order to reduce the frame of the display panel, the flexible circuit board 300 is bent to the back of the display panel.
[0036] Figure 2 This is a front structural schematic diagram of a display panel in an unbent state provided by another embodiment of the present application. Figure 2 The display panel shown is Figure 1 The difference between the display panels shown is that the lengths of the first segments 111 of the first data signal lines 110 are the same, and the widths of the first segments 111 of at least some of the first data signal lines 110 are different. Therefore, the resistance of different first data signal lines 110 can be adjusted by adjusting the width of the first segments 111 (i.e., adjusting the width of the widened portion). Optionally, the width of the first segment 111 is proportional to the winding length of the first data signal line 110. If the winding length of the first data signal line 110 is longer, the width of the first segment 111 is wider. In the embodiment of the present application, the closer the first data signal line 110 is to the opening 200, the longer the winding length, and accordingly, the wider the width of the first segment 111, so that the resistance of different first data signal lines 110 can be the same. Although the widths of different first data signal lines 110 are different, the widths of the same first data signal line 110 at different positions can be equal or unequal.
[0037] Figure 3 This is a front structural schematic diagram of a display panel in an unbent state provided by another embodiment of the present application. Figure 3 The display panel shown is Figure 1The difference of the display panel shown is that the display panel also includes a plurality of switch modules 400 corresponding to the data signal line 100 one by one, and the switch module 400 is connected to the data signal line 100. In the embodiment of the present application, the switch module 400 is also called SD Switch, which is used to control the switch of the data signal line. In the embodiment of the present application, the switch module 400 is located in the bending area L2. When the first display area L1 of the display panel works alone, the switch module 400 is in a disconnected state. At this time, the second display area L3 is not displayed, which can save power and improve the battery life of the display panel. Optionally, the switch module 400 is located on the side of the bending area L2 close to the second display area L3. When the switch module 400 is in a disconnected state, at least part of the bending area L2 can be displayed. Alternatively, the switch module 400 is located on the side of the bending area L2 close to the first display area L1. When the switch module 400 is in a disconnected state, the bending area L2 is not displayed.
[0038] Figure 4 This is a front structural schematic diagram of a display panel in an unbent state provided by another embodiment of the present application. Figure 4 The display panel shown is Figure 1 The difference between the display panels shown is that the opening 200 is located in the second display area L3. In the embodiment of the present application, no matter the opening 200 is located in the first display area L1 or the second display area L3, the resistance of the first data signal line 110 and the second data signal line 120 can be made consistent by widening at least a portion of the first data signal line 110 in the bending area L2.
[0039] In a second aspect, an embodiment of the present application further provides a display panel, comprising a first display portion, a bending portion, and a second display portion arranged in sequence along a first direction, the second display portion being foldable to the back of the first display portion via the bending portion, and in a folded state, the bending portion and / or the second display portion being displayable; in an unfolded state, the bending portion is not displayable, and the first display portion and the second display portion are independently displayable; the display panel further comprises: a plurality of data signal lines arranged along a second direction, the first direction and the second direction intersecting; the display panel having an opening, the plurality of data signal lines comprising at least one first data signal line partially surrounding the opening and at least one second data signal line not surrounding the opening; along the second direction, at least a portion of the width of the first data signal line at the bending portion is greater than a width of the second data signal line at the bending portion.
[0040] Figure 5 It is a schematic diagram of the side structure of a display panel in an unbent state according to an embodiment of the present application. Figure 6 yes Figure 5 The side structural schematic diagram of the display panel in a folded state is shown.
[0041] like Figure 5 or Figure 6As shown, the display panel includes a first display portion 510, a bending portion 520, and a second display portion 530. The first display portion 510 is located in the first display area L1, the bending portion 520 is located in the bending area L2, and the second display portion 530 is located in the second display area L3. In the embodiment of the present application, the second display portion 530 can be folded to the back of the first display portion 510 through the bending portion 520, as shown in FIG. Figure 6 As shown. In the folded state, the bending portion 520 and the second display portion 530 can be displayed; in the unfolded state, the bending portion 520 cannot be displayed, and the first display portion 510 and the second display portion 530 can be displayed independently. Therefore, the display panel of the present application has the following usage states. For example, when the display panel is in a folded state (i.e., unused state), simple information such as date and time can be displayed through the bending portion 520; or, key information (e.g., date, time, prompt message, etc.) can be displayed through the second display portion 530. For another example, when the display panel is in the unfolded state (i.e., used state), the bending portion 520 cannot be displayed, and the first display portion 510 and the second display portion 530 can be displayed independently, that is, the first display portion 510 and the second display portion 530 can display different content. When the display panel is unfolded, due to the low resolution of the bending portion 520, if the bending portion 520 is displayed simultaneously with the first display portion 510 and / or the second display portion 530, uneven display will be caused, affecting the display effect; in addition, the first display portion 510 and the second display portion 530 can be displayed independently, and the bending portion 520 is not displayed, which will not affect the overall display effect. For another example, if only the first display portion 510 is required to display, the switch module 400 is disconnected, and the page content is only displayed on the first display portion 510. For another example, if only the second display portion 530 is required to display, the switch module 400 is turned on and the clock signal is adjusted by software, and the page content is only displayed on the second display portion 530.
[0042] Figure 7 This is a front structural schematic diagram of a display panel in an unbent state provided by another embodiment of the present application. Figure 8 This application Figure 7 The side structural schematic diagram of the display panel in a folded state is shown. Figure 7 The display panel shown is Figure 1The difference between the display panels shown is that the first display portion 510 includes a first sub-display portion 511, a sub-bending portion 512 and a second sub-display portion 513 arranged in sequence along a first direction, the sub-bending portion 512 connects the first sub-display portion 511 and the second sub-display portion 513, and the first sub-display portion 511 and the second sub-display portion 513 are folded or unfolded through the sub-bending portion 512. In the embodiment of the present application, the areas of the first sub-display portion 511 and the second sub-display portion 513 are equal, so that the first sub-display portion 511 and the second sub-display portion 513 can be aligned after being folded. Optionally, the second display portion 530 and the first sub-display portion 511 and the second sub-display portion 513 are equal in area, so that the display panel can be folded twice so that the second display portion 530, the first sub-display portion 511 and the second sub-display portion 513 are aligned, as shown in FIG. Figure 8 As shown, after folding, the second display portion 530 is exposed to the outside and can be displayed, while the first sub-display portion 511 and the second sub-display portion 513 are hidden and cannot be displayed. At this time, key information, such as date, time, prompt message, etc., can be displayed on the second display portion 530, and information such as date and time can also be displayed on the bent portion 520. In the embodiment of the present application, the display panel can be folded twice to reduce the area of the display panel and improve the portability of the display panel.
