Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the development of display technology, flexible organic light emitting diode (OLED) display panels have been widely used in various fields such as televisions, smart phones, smart wearables, VR, automotive displays, etc. due to their many advantages such as lightness, bendability, good shock resistance, fast response and adaptability to wearable products.

[0003] A display device includes a display panel, which includes a display portion and a binding portion. The binding portion is provided with multiple pins for electrically connecting to a circuit board (such as a flexible circuit board) or a circuit board (such as a wiring harness) or other electronic components. In some products, such as watches or foldable laptops, the binding portion has multiple (at least two) outwardly protruding corners.

[0004] In related art, the corners of the binding portion are all vertical, meaning the two sides forming the corners are perpendicular. During the transportation of the display panel, the vertical corners may collide with the pallet (the packaging used to carry and protect the display panel). When a vertical corner collides with the pallet, stress is concentrated at the corner, increasing the risk of bending or even cracking. Summary of the Invention

[0005] Embodiments of the present disclosure provide a display panel and a display device, which can reduce the risk of bending and breaking of a binding portion of the display panel and improve the reliability of the display panel and the display device.

[0006] To achieve the above objectives, the embodiments of the present disclosure adopt the following technical solutions:

[0007] In one aspect, embodiments of the present disclosure provide a display panel. The display panel includes a display portion and a binding portion. The binding portion is located on one side of the display portion and includes multiple corners. At least one corner is curved, with the curved edge of the curved corner protruding away from the binding portion. The binding portion includes multiple first pins arranged in parallel along a first direction, with a line connecting ends of the multiple first pins near the curved corner forming an arc, and the arc protruding away from the multiple first pins.

[0008] The display panel provided by the embodiment of the present disclosure sets at least one corner of the binding portion into an arc shape. The arc-shaped corner can reduce the area of ​​the corner of the binding portion and reduce the risk of the corner colliding with the tray. Moreover, when the arc-shaped corner of the binding portion collides with the tray, the stress on the arc-shaped corner is more dispersed (compared to the vertical corner), thereby reducing the risk of bending or cracking at the arc-shaped corner of the binding portion and improving the reliability of the display panel. The line connecting the ends of the multiple first pins close to the arc-shaped corner is an arc, and the arc-shaped corner and the above-mentioned line both protrude in the direction away from the binding portion, that is, the ends of the multiple first pins close to the arc-shaped corner are set along the bending direction of the arc-shaped corner. In this way, a larger number of first pins can be set at the arc-shaped corner, so as to keep the number of first pins on the binding portion unchanged.

[0009] In some embodiments, the plurality of first pins are close to one end of the arc-shaped corner and have the same shortest distance as the arc-shaped corner.

[0010] In some embodiments, along the first direction and from the multiple first pins to the boundary of the arc corner, the length of the multiple first pins located at the arc corner gradually decreases along the second direction, the second direction intersects with the first direction, and the multiple first pins are flush with one end away from the arc corner.

[0011] In some embodiments, the binding portion further includes a plurality of signal lines and a plurality of second pins. One second pin is electrically connected to one signal line. The first pin is electrically insulated from the plurality of signal lines, and the plurality of first pins are located on at least one side of the plurality of second pins along the first direction.

[0012] In some embodiments, the binding portion includes two first corners, the two first corners being located on a side of the binding portion away from the display portion. The two first corners are curved corners. The binding portion includes two groups of first pins, one group of first pins being located at each first corner. Each group of first pins includes a plurality of first pins arranged in parallel along a first direction.

[0013] In some embodiments, along the first direction, the size of the binding portion is larger than the maximum size of the display portion. The binding portion further includes two second corners, the two second corners being closer to the display portion than the two first corners. The two second corners are curved corners, or the two second corners are right-angled corners.

[0014] In some embodiments, the display panel further includes a bending portion, which is disposed between the display portion and the binding portion; along the first direction, a size of the bending portion is smaller than a size of the binding portion.

[0015] In some embodiments, the display panel includes multiple binding portions arranged in parallel along a first direction, each binding portion including a third corner located on a side of the binding portion away from the display portion and proximal to the other binding portions; the two third corners are curved corners. The binding portion includes multiple groups of first pins, with one group of first pins located at each third corner; each group of first pins includes multiple first pins arranged in parallel along the first direction.

[0016] In some embodiments, the binding portion further includes a fourth corner, the fourth corner being located on a side of the binding portion away from the display portion and away from other binding portions; the fourth corner being an arc-shaped corner; and a group of first pins being disposed at one fourth corner.

[0017] In some embodiments, along the first direction, the display portion includes a plurality of display sub-portions spaced apart from each other and a bending sub-portion located between two adjacent display sub-portions. A binding portion is located on one side of a display sub-portion and connected to the display sub-portion.

[0018] In another aspect, an embodiment of the present disclosure further provides a display device, including a display panel and a flexible circuit board connected to a binding portion of the display panel.

[0019] In some embodiments, along the first direction, the size of the binding portion is larger than the maximum size of the display portion of the display panel. When the binding portion is bent toward the non-display side of the display portion, opposite ends of the binding portion in the first direction extend beyond opposite sides of the display portion in the first direction.

[0020] In some embodiments, along a first direction, the display portion of the display panel includes a plurality of display sub-portions spaced apart from each other, and a bending sub-portion located between two adjacent display sub-portions. The display panel also includes a plurality of binding portions arranged in parallel along the first direction, with one binding portion located on one side of each display sub-portion and connected to the display sub-portion. Two adjacent binding portions are electrically connected via a flexible printed circuit board.

[0021] In some embodiments, the display device is a wearable display device or a foldable display device.

[0022] The display device provided by the embodiments of the present disclosure includes the display panel of any of the above embodiments. The beneficial effects that can be achieved by the display device can refer to the beneficial effects that can be achieved by the above display panels, which will not be repeated here.

[0039] Some embodiments of the present disclosure provide a display device 1000, referring to Figure 1 and Figure 5 The display device 1000 can be any product or component with a display function, such as a laptop computer, a tablet computer, a mobile phone, a personal digital assistant (PDA), a navigator, a wearable display device, a foldable display device, a virtual reality (VR) device, etc.

[0040] In some embodiments, see Figure 1 and Figure 5 The display device 1000 includes a display panel 100, and the display panel 100 includes a display portion 110 and a binding portion 120. The binding portion 120 is located on one side of the display portion 110. For example, Figure 1 As shown, the binding portion 120 is located on the lower side of the display portion 110 .

[0041] The display portion 110 includes a display area A and a peripheral area B disposed on at least one side of the display area A. Figure 1 In the example, the peripheral area B surrounds the display area A. The display area A is configured to have multiple sub-pixels, which are used to display image information. The peripheral area B is configured to have circuit traces and gate drive circuits.

[0042] In some embodiments, the binding portion 110 includes a plurality of corners 10 .

[0043] For example, see Figure 1 and Figure 5 , along the first direction X( Figure 1 The size of the binding portion 120 is larger than the maximum size of the display portion 110 of the display panel 100. Figure 4As shown, when the binding portion 120 is bent to the non-display side of the display portion 110 , opposite ends of the binding portion 120 in the first direction X extend out from opposite sides of the display portion 110 in the first direction X.

[0044] At this time, the binding portion 120 may include four corners 10. The display device 1000 may be a watch, a bracelet or other wearable display device, or a notebook touch function bar (NoteBook touch bar). For example, Figure 1 As shown, the outer contour of the display portion 110 is circular, and the display device 1000 may be a watch. Figure 6 As shown, the outer contour of the display portion 110 is a rectangle, and the display device 1000 may be a wristband.

[0045] For example, Figure 7 and Figure 8 As shown, along the first direction X( Figure 1 The binding portion 120 is smaller than the display portion 110. The display portion 110 of the display panel 100 includes a plurality of display sub-portions 111 spaced apart from each other, and a bending sub-portion 112 located between two adjacent display sub-portions 111. The display panel 100 includes a plurality of binding portions 120 arranged in parallel along the first direction X. Each binding portion 120 is located on one side of a display sub-portion 111 and is connected to the display sub-portion 111. Two adjacent binding portions 120 can be electrically connected via a flexible printed circuit board (FPC).

[0046] In this case, the binding portion 120 includes two corners 10 on a side away from the display portion 110. Here, the display device 1000 can be a mobile phone, an electronic billboard or signboard, a handheld or portable computer, or other foldable display devices.

[0047] Among them, see Figure 1 At least one of the multiple corners 10 of the binding portion 120 is a curved corner 101. The curved edge of the curved corner 101 protrudes away from the binding portion 120. That is, the edge of the curved corner 101 is further away from the center of the binding portion 120 than the line connecting the two ends of the curved corner 101. The curved shape of the curved corner 101 creates a smooth transition at the corner 10, which helps to disperse the stress applied to the curved corner 101 during a collision.

[0048] It is understood that by configuring at least one corner 10 of the binding portion 120 to be curved, the curved corner 101 can reduce the area of ​​the corner 10 of the binding portion 120, thereby reducing the risk of the curved corner 101 colliding with the tray. Furthermore, when the curved corner 101 of the binding portion 120 collides with the tray, the stress on the curved corner 101 is more dispersed (compared to a vertical corner), thereby reducing the risk of bending, splitting, or cracking at the curved corner 101 of the binding portion 120, thereby improving the reliability of the display panel 100.

[0049] In addition, see Figure 6 The binding portion 110 is configured to electrically connect to other electronic components (such as a panel driver chip) and a circuit board (such as a flexible circuit board (FPC). The binding portion 120 includes a plurality of signal lines, a plurality of pins 20 arranged in parallel along the first direction X, and a panel driver IC (DIC) disposed on the binding portion 120.

[0050] like Figure 1 and Figure 2 As shown, the plurality of pins 20 include a plurality of first pins 21 and a plurality of second pins 22. The plurality of first pins 21 are electrically insulated from the plurality of signal lines and are disposed on at least one side of the plurality of second pins 22 along the first direction X. The first pins 21 are used to reduce the risk of the second pins 22 falling off or warping. One second pin 22 is electrically connected to one signal line and is configured to transmit a control signal to the display portion 110.

[0051] After the flexible printed circuit board (FPC) is connected to the multiple pins 20 of the binding portion 120, dynamic pulling or squeezing may occur between the two, resulting in stress between the interconnected pins 20. Under the action of this stress, the pins 20 located at the ends of the arrangement direction of the multiple pins 20 (the first direction X) are at a greater risk of falling off or warping. Therefore, providing multiple first pins 21 on both sides of the multiple second pins 22 along the first direction X helps reduce the risk of the second pins 22 falling off or warping, thereby reducing the problem of display abnormalities caused by the display portion 110 being unable to receive control signals.

[0052] It should be noted that the flexible circuit board FPC can be provided with a variety of electronic components, such as Figure 6 As shown, for example, a touch IC TIC (Touch IC), a timing controller, and a power management IC PMIC (Power Management IC) are provided on the flexible circuit board FPC, but the present disclosure is not limited thereto.

[0053] like Figure 1 and Figure 2As shown, at least part of the first pins 21 are disposed at the arc corner 101 . A line L1 connecting one end of the first pins 21 near the arc corner 101 is an arc, and the arc corner 101 and the line L1 protrude away from the first pins 21 .

[0054] For example, see Figure 2 , along the first direction X, with the plurality of first pins 21 pointing toward the boundary of the arc-shaped corner 101 where the plurality of first pins 21 are located, that is, the direction in which the second pins 22 point toward the arc-shaped corner 101, the lengths of the plurality of first pins 21 at the arc-shaped corner 101 gradually decrease along the second direction Y, and the ends of the plurality of first pins 21 away from the arc-shaped corner 101 are flush. The second direction Y intersects the first direction X, and for example, may be perpendicular or approximately perpendicular to the first direction X. In this way, a greater number of first pins 21 can be provided at the arc-shaped corner 101, reducing the risk of the second pins 22 falling off, warping, or other problems.

[0055] For example, the shortest distance S between the ends of the multiple first pins 21 closest to the curved corner 101 and the curved corner 101 is equal, that is, the end of each first pin 21 closest to the curved corner 101 forms a portion of a ring with the curved corner 101. This arrangement helps to further disperse the stress on the curved corner 101, further reducing the risk of bending, splitting, or cracking at the curved corner 101 of the binding portion 120.

[0056] It should be noted that the shortest distance S between the end of the first pin 21 close to the arc corner 101 and the arc corner 101 can be, for example, the shortest distance S between the corner point M of the first pin 21 close to the boundary of the arc corner 101 and the boundary of the arc corner 101.

[0057] In some embodiments, as Figure 1 As shown, the binding portion 120 includes two first corners 102, and the two first corners 102 are both located on the side of the binding portion 120 away from the display portion 110, and the two first corners 102 are arc-shaped corners 101. Figure 4 When the binding portion 120 is folded to the non-display side of the display panel 100, the risk of the two first corners 102 colliding with the tray can be reduced. When the first corner 102 collides with the tray, the stress on the first corner 102 is more dispersed (compared to the vertical corner), thereby reducing the risk of bending, splitting or cracking at the first corner 102 of the binding portion 120, thereby improving the reliability of the display panel 100.

[0058] Among them, the binding part 120 includes two groups of first pins 21, one group of first pins 21 is set at a first corner 102, and each group of first pins 21 includes multiple first pins 21 arranged in parallel along the first direction X, so as to reduce the risk of the second pins 22 adjacent to the first corner 102 falling off, warping and other problems, thereby reducing the problem of display abnormality caused by the display part 110 being unable to receive the control signal.

[0059] For example, see Figure 1 , along the first direction X( Figure 1 The binding portion 120 is larger than the maximum size of the display portion 110 (in the horizontal direction). The binding portion 120 may include four corners 10, two of which are located on the side of the binding portion 120 away from the display portion 110 and are referred to as first corners 102. The other two corners 10 are located on the side of the binding portion 120 close to the display portion 110 and are referred to as second corners 103.

[0060] Here, the two second corners 103 may be arc-shaped corners 101 (see Figure 3 ), or a right-angle corner (see Figure 1 ).

[0061] For example, see Figure 3 , along the first direction X( Figure 1 In the horizontal direction), the two second corners 103 can be arc-shaped corners 101. Figure 4 When the binding portion 120 is folded to the non-display side of the display panel 100, the risk of the two second corners 103 colliding with the tray can be reduced. When the second corner 103 collides with the tray, the stress on the second corner 103 is more dispersed (compared to the vertical corner), thereby reducing the risk of bending, splitting or cracking at the second corner 103 of the binding portion 120, thereby improving the reliability of the display panel 100.

[0062] The display panel 100 further includes a bending portion 130 disposed between the display portion 110 and the binding portion 120. Along the first direction X, the bending portion 130 is smaller than the binding portion 120 to reduce bending process difficulty and manufacturing cost.

[0063] In other embodiments, Figure 7 and Figure 8 As shown, along the first direction X, the display portion 110 includes a plurality of display sub-portions 111 spaced apart and a bending sub-portion 112 located between two adjacent display sub-portions 111 . A binding portion 120 is located on one side of a display sub-portion 111 and connected to the display sub-portion 111 .

[0064] For example, Figure 7As shown, the display panel 100 includes a plurality of binding portions 120 arranged in parallel along a first direction X, each binding portion 120 includes a third corner 104, the third corner 104 is located on the side of the binding portion 120 away from the display portion 110 and close to other binding portions 120, and the third corner 104 is an arc-shaped corner 101.

[0065] Thus, see Figure 7 When the display panel 100 is a folding display panel, the risk of the third corners 104 of the two adjacent binding parts 120 colliding with the folding mechanism (located in the bending sub-part 112) of the display panel 100 during the operation of folding or unfolding the display panel 100 can be reduced. In addition, when the third corner 104 collides with the folding mechanism, the stress on the third corner 104 is more dispersed, thereby reducing the risk of bending, splitting or cracking at the third corner 104 of the binding part 120.

[0066] Among them, the binding portion 120 includes multiple groups of first pins 21, and a group of first pins 21 is set at a third corner 104; each group of first pins 21 includes multiple first pins 21 arranged in parallel along the first direction X, so as to reduce the risk of the second pins 22 adjacent to the third corner 104 falling off, warping and other problems.

[0067] On this basis, if Figure 8 As shown, each binding portion 120 includes a fourth corner 105 , which is located on a side of the binding portion 120 away from the display portion 110 and away from other binding portions 120 , and is an arc-shaped corner 101 .

[0068] Arranged in this way, the risk of the fourth corner 105 colliding with the pallet can be reduced, and when the fourth corner 105 collides with the pallet, the stress on the fourth corner 105 is more dispersed, thereby reducing the risk of bending, splitting or cracking at the fourth corner 105 of the binding portion 120.

[0069] Among them, the binding portion 120 includes multiple groups of first pins 21, and a group of first pins 21 is set at a fourth corner 105; each group of first pins 21 includes multiple first pins 21 arranged in parallel along the first direction X, so as to reduce the risk of the second pins 22 adjacent to the fourth corner 105 falling off, warping and other problems.

[0070] For example, see Figure 8The display panel 100 includes two display sub-sections 111 spaced apart along a first direction X, and a bent sub-section 112 located between the two adjacent display sub-sections 111. Each binding portion 120 includes a third corner 104 and a fourth corner 105. The third corner 104 is located on a side of the binding portion 120 away from the display portion 110 and close to the other binding portion 120. The fourth corner 105 is located on a side of the binding portion 120 away from the display portion 110 and away from the other binding portion 120.

[0071] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0072] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
