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 rapid development of display technology, display technologies such as liquid crystal display devices, organic light-emitting display devices, quantum dot light-emitting display devices and micro light-emitting display devices have been widely penetrated into people's daily lives. For example, smart phones, wearable watches, televisions, laptops and car displays have gradually spread throughout people's lives.

[0003] In some related technologies, a display device includes a display panel and a circuit board, the display panel has a bending area, the circuit board is connected to the end of the display panel, and the display panel can be bent along a first axis in the bending area, so that the circuit board is bent to the back side of the display panel. However, the signal line in the display panel is prone to breakage in the bending area, resulting in abnormal display of the display panel (such as bright lines or dark lines), and the reliability of the display panel is low. Summary of the invention

[0004] An object of the embodiments of the present disclosure is to provide a display panel and a display device, which are used to reduce the risk of abnormal display of the display panel caused by broken signal lines and improve the reliability of the display panel.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present disclosure.

[0047] Unless the context requires otherwise, throughout the specification and claims, the term "including" is to be interpreted as an open, inclusive meaning, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "examples" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics described may be included in any one or more embodiments or examples in any appropriate manner.

[0048] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0049] When describing some embodiments, the expression "connection" and its derivatives may be used. The term "connection" should be understood in a broad sense. For example, "connection" can be a mechanical connection or an electrical connection; it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0050] “At least one of A, B, and C” has the same meaning as “at least one of A, B, or C” and both include the following combinations of A, B, and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B, and C.

[0051] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.

[0052] As used herein, the term "if" is optionally interpreted to mean "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined that" or "if [a stated condition or event] is detected" are optionally interpreted to mean "upon determining that" or "in response to determining that" or "upon detecting [a stated condition or event]" or "in response to detecting [a stated condition or event]," depending on the context.

[0053] The use of "adapted to" or "configured to" herein is meant to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0054] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0055] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of variation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0056] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within the acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism may be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity may also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality may be, for example, the difference between the two equalities is less than or equal to 5% of either one.

[0057] It will be understood that when a layer or an element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present between the layer or element and the other layer or substrate.

[0058] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of the layers and the area of ​​the regions are exaggerated for clarity. Therefore, variations in the shapes relative to the drawings due to, for example, manufacturing techniques and / or tolerances are conceivable. Therefore, the exemplary embodiments should not be interpreted as being limited to the shapes of the regions shown herein, but include shape deviations due to, for example, manufacturing. For example, an etched region shown as a rectangle will typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shapes of the regions of the device, and are not intended to limit the scope of the exemplary embodiments.

[0059] like Figure 1 As shown, some embodiments of the present disclosure provide a display device 1000, which may be any device that displays images, whether in motion (eg, video) or fixed (eg, still image), and whether text or text.

[0060] For example, see Figure 1 and Figure 2 The display device 1000 can be any product or component with display function, such as a portable display product, a wearable device, a television, a laptop computer, a tablet computer, a personal digital assistant (PDA), a navigator, a flight display, a car display, a clock, a spliced ​​display, a signboard, an electronic billboard, a shopping mall display, etc.

[0061] For example, Figure 1 As shown, the display device 1000 can be Figure 1 For another example, see Figure 2 , the display device 1000 may be Figure 2 The mall display shown in .

[0062] It should be noted that, according to different application scenarios, the display device 1000 can be a flat display device, a curved display device, a folding display device, etc., and the shape of the display surface of the display device 1000 can be any one of a circular, elliptical, polygonal or irregular shape, but the embodiments of the present disclosure are not limited to this.

[0063] The following uses the display device 1000 as an example. Figure 1 Taking the illustrated mobile phone as an example, some embodiments of the present disclosure are schematically described, but the implementation of the present disclosure is not limited thereto, and any other display device 1000 may also be considered as long as the same technical concept is applied.

[0064] In some embodiments, see Figure 3 The display device 1000 includes a display panel 100, and the display panel 100 may include a display side and a non-display side that are arranged opposite to each other. The display side is the side of the display panel 100 used for display, that is, Figure 3 The upper side in the figure, the non-display side is the other side of the display panel 100 opposite to the display side.

[0065] The display panel 100 may be of various types, which may be selected and set according to actual needs. For example, the display panel 100 may be a liquid crystal display panel (LCD), an organic light emitting diode (OLED), a quantum dot light emitting diode (QLED), a micro light emitting diode (Micro LED), a micro organic light emitting diode (Micro OLED), a sub-millimeter light emitting diode (Mini LED), etc., which are not specifically limited in the embodiments of the present disclosure.

[0066] In some embodiments, see Figure 3The display device 1000 may further include a housing 200 , a cover plate 300 , a circuit board 400 and other electronic components. The display panel 100 and the circuit board 400 may be disposed in the housing 200 .

[0067] For example, Figure 3 As shown, the housing 200 may be a box-shaped structure with an opening, and the cover plate 300 is disposed on the display side of the display panel 100 and is located at the opening of the housing 200. The display panel 100 and the circuit board 400 may be disposed in the housing 200, and the circuit board 400 may be bound to the display panel 100 at the end of the display panel 100 and bent to the back side of the display panel 100 to reduce the frame of the display panel 100 and increase the screen-to-body ratio.

[0068] Among them, Figure 4 As shown, the end of the display panel 100 is, for example, provided with a plurality of first binding pins 110, and the end of the circuit board 400 is, for example, provided with a plurality of second binding pins 410, and the first binding pins 110 are connected with the second binding pins 410 to connect the circuit board 400 with the display panel 100, thereby providing a display signal to the display panel 100.

[0069] In some embodiments, see Figure 4 The display panel 100 has a display area A and a peripheral area B disposed on at least one side of the display area A. Figure 4 In the figure, the peripheral area B is arranged around the display area A for illustration.

[0070] The display area A is an area for displaying images, and is configured to set a plurality of sub-pixels P, which can be understood as the smallest light-emitting unit in the display panel 100. The peripheral area B is an area for not displaying images, and is configured to set a driving circuit, circuit wiring, and connection structure, such as a gate driving circuit, a source driving circuit, and a first binding pin 110.

[0071] For example, Figure 4 As shown, the display area A is provided with a plurality of sub-pixels P, and the plurality of sub-pixels P are arranged in a plurality of rows and columns, each row includes at least two sub-pixels P arranged along a first direction X, and each column includes at least two sub-pixels P arranged along a second direction Y.

[0072] It should be noted that the first direction X is the row direction of the plurality of sub-pixels P, and the second direction Y is the column direction of the plurality of sub-pixels P. The first direction X and the second direction Y intersect, for example, the first direction X and the second direction Y are perpendicular.

[0073] In some embodiments, see Figure 4 and Figure 5The peripheral area B includes a bending area B1 and a binding area B2, the bending area B1 and the binding area B2 are arranged on one side of the display area A, and the bending area B1 is arranged between the display area A and the binding area B2. For example, the display area A, the bending area B1 and the binding area B2 are arranged along the second direction Y.

[0074] The bending area B1 is an area where the display panel 100 is bent. For example, the display panel 100 can be bent along the first axis in the bending area B1. The binding area B2 is an area where the circuit board 400 is connected to the display panel 100. For example, the first binding pin 110 is disposed in the binding area B2.

[0075] On this basis, see Figure 4 , Figure 5 and Figure 6 The display panel 100 also includes a plurality of signal lines 30, the signal lines 30 include a first routing segment 31, a second routing segment 32 and a third routing segment 33, the first routing segment 31 is located on the side of the bending area B1 away from the binding area B2 and extends to the display area A, the third routing segment 33 is located on the side of the bending area B1 away from the display area A, one end of the second routing segment 32 is connected to the first routing segment 31, and the other end passes through the bending area B1 and is connected to the third routing segment 33. In addition, the third routing segment 33 can be connected to the first binding pin 110, for example, to receive a display signal. It should be noted that the second routing segment 32 can, for example, extend along the second direction Y.

[0076] However, in the related art, when the bending area of ​​the display panel is subjected to external force, the risk of the second wiring segment being broken is relatively high, resulting in abnormal display of the display panel (such as the appearance of bright or dark lines), making the reliability of the display panel low.

[0077] Based on this, see Figure 5 , Figure 6 and Figure 7 The display panel 100 provided in some embodiments of the present disclosure further includes a plurality of adapter wires 40, the adapter wires 40 include a first adapter segment 41, a second adapter segment 42 and a third adapter segment 43, the first adapter segment 41 is located on the side of the bending area B1 away from the binding area B2, and is connected to the first routing segment 31. The third adapter segment 43 is located on the side of the bending area B1 away from the display area A, and is connected to the third routing segment 33. One end of the second adapter segment 42 is connected to the first adapter segment 41, and the other end passes through the bending area B1 and is connected to the third adapter segment 43. It should be noted that the second adapter segment 42 can, for example, extend along the second direction Y.

[0078] In this case, the signal line 30 is connected in the bending area B1 through the second routing segment 32 and at least one second transfer segment 42. In this way, in the bending area B1, as long as there is a second routing segment 32 or a second transfer segment 42 of the signal line 30 that is not disconnected, the signal line 30 can still transmit electrical signals normally, thereby reducing the risk of abnormal display of the display panel 100 caused by disconnection of the signal line 30, and improving the reliability of the display panel 100.

[0079] In addition, there is at least one second routing segment 32 and / or second transfer segment 42 between the second routing segment 32 and the connected second transfer segment 42. In this way, the distance between the second routing segment 32 and the connected second transfer segment 42 of the same signal line 30 in the bending area B1 is set larger, which can reduce the local force of the bending area B1, resulting in the risk of both the second routing segment 32 and the second transfer segment 42 transmitting the same signal being broken, thereby further reducing the risk of abnormal display of the display panel 100 caused by the breakage of the signal line 30, thereby improving the reliability of the display panel 100.

[0080] Exemplarily, the distance L1 between the second routing segment 32 and the connected second transfer segment 42 is greater than or equal to the width of an employee's finger. For example, the distance L1 between the second routing segment 32 and the connected second transfer segment 42 is greater than or equal to 10 mm, which can reduce the risk of the second routing segment 32 and the second transfer segment 42 transmitting the same signal being broken due to the local pressure of the fingers on the display panel 100 during the process of the personnel carrying the display panel 100, thereby improving the reliability of the display panel 100.

[0081] It should be understood that the signal line 30 may include at least one of any circuit lines such as a data line 310 , a power line, and a clock signal line that pass through the bending area B1 and are connected to the circuit board 400 .

[0082] Below, some embodiments of the present disclosure are schematically described by taking the signal line 30 including the data line 310 as an example, but the implementation of the present disclosure is not limited to this, and any other circuit routing that passes through the bending area B1 and is connected to the circuit board 400 can also be considered, as long as the same technical concept is applied.

[0083] For example, Figure 4 As shown, the display panel 100 may further include a source driving circuit 101 and a plurality of data lines 310, wherein the data lines 310 are arranged in the display area A and extend to the peripheral area B along the second direction Y to connect to the source driving circuit 101. One data line 310 may be connected to one column of sub-pixels P.

[0084] In some embodiments, Figure 8As shown, the display panel 100 includes a first line cluster 3 and a second line cluster 4, the first line cluster 3 includes a plurality of second routing segments 32 arranged adjacently, and the second line cluster 4 includes a plurality of second switching segments 42 arranged adjacently. Here, the plurality of second routing segments 32 arranged adjacently means that there are no other routings between the plurality of second routing segments 32. The plurality of second switching segments 42 arranged adjacently means that there are no other routings between the plurality of second switching segments 42. In this case, the plurality of second routing segments 32 in a first line cluster 3 can be respectively connected to the plurality of second switching segments 42 in a second line cluster 4, and the second routing segments 32 and the second switching segments 42 are respectively centrally arranged for easy distinction and maintenance.

[0085] For example, see Figure 8 , the display panel 100 has a first center line S1 extending along the second direction Y. Along the first direction X, on either side of the first center line S1, the first line clusters 3 and the second line clusters 4 are alternately arranged, and a second routing segment 32 of a first line cluster 3 is connected to a second adapter segment 42 of a second line cluster 4 that is close to and adjacent to the first center line S1. In this case, the length difference of the adapter wires 40 connected to each signal line 30 is small, which is conducive to the voltage drop difference of each signal line 30.

[0086] Among them, multiple signal lines 30 and multiple switching lines 40 can be symmetrical about the first center line S1, for example. This is conducive to reducing the difference in resistance of each signal line 30, such as reducing the difference in resistance of each data line 310, thereby reducing the difference in driving current generated by the sub-pixel P, and further improving the uniformity of display brightness.

[0088] Among them, multiple signal lines 30 and multiple switching lines 40 can be symmetrical about the first center line S1, for example. This is conducive to reducing the difference in resistance of each signal line 30, such as reducing the difference in resistance of each data line 310, thereby reducing the difference in driving current generated by the sub-pixel P, and further improving the uniformity of display brightness.

[0092] For example, Fig. 9 and Fig.11 As shown, the second routing segments 32 and the second transfer segments 42 are arranged alternately. At this time, the first sub-cluster 61 and the second sub-cluster 62 include a plurality of second routing segments 32 and a plurality of second transfer segments 42, respectively. Fig. 9 In the figure, a first sub-cluster 61 includes two second routing segments 32 and two second switching segments 42, and a second sub-cluster 62 includes two second routing segments 32 and two second switching segments 42.

[0093] In addition, see Figure 8 , Fig. 9 , Fig.10 and Fig.11 In the above-mentioned first sub-cluster 61, the two adjacent first line segments 610 are the first target line segment 611 and the second target line segment 612, the second line segment 620 connected to the first target line segment 611 is the third target line segment 621, and the second line segment 620 connected to the second target line segment 612 is the fourth target line segment 622.

[0094] At this time, along the first direction X, the first target line segment 611 , the second target line segment 612 , the third target line segment 621 , and the fourth target line segment 622 may be arranged in the following two examples, for example.

[0095] Example 1, such as Figure 8 and Fig. 9As shown, along the first direction X, the first target line segment 611, the second target line segment 612, the fourth target line segment 622, and the third target line segment 621 are arranged in sequence.

[0096] On this basis, the display panel 100 may include a first subcluster group 71 and a second subcluster group 72, the first subcluster group 71 includes two adjacently arranged first subclusters 61, the second subcluster group 72 includes two adjacently arranged second subclusters 62, and along the first direction X, the first subcluster group 71 and the second subcluster group 72 are alternately arranged.

The first sub-section 431 and the second sub-section 432 are connected through the second transfer section 82, and the second sub-section 432 is connected to the second transfer section 42.

[0099] At this time, in the same first sub-cluster group 71, the first sub-segment 431 of one first sub-cluster 61 is located on the side of the first adapter portion 81 and the second adapter portion 82 close to the bending area B1. The first sub-segment 431 of another first sub-cluster 61 is located on the side of the first adapter portion 81 and the second adapter portion 82 away from the bending area B1. In this case, the first adapter portion 81 and the second adapter portion 82 can be arranged along the first direction X, for example, and the adapter line 40 will not cross, the routing is more regular, and the structure is simple.

[0100] Example 2, such as Fig.10 and Fig.11 As shown, along the first direction X, the first target line segment 611, the second target line segment 612, the third target line segment 621, and the fourth target line segment 622 are arranged in sequence.

The third sub-section 441 and the first routing section 31 or the third routing section 33 are connected through the first transfer portion 81 ( Fig.11 For example, the second redundant transfer section 440 is the first transfer section 41, and the first transfer section 41 is connected to the first routing section 31 through the first transfer portion 81. The third sub-segment 441 and the fourth sub-segment 442 are connected through the second transfer portion 82, and the second sub-segment 432 is connected to the second transfer section 42.

And / or, at least one first routing segment 31 is spaced between the fourth sub-segments 442 connected to two adjacent second routing segments 32. Fig.11 In the example, a first routing segment 31 is provided between the fourth sub-segment 442 connected to two adjacent second routing segments 32. In this case, the first adapter 81 and the second adapter 82 are staggered in the first direction X, and the routing length of the adapter line 40 is shorter, which is conducive to reducing the voltage drop.

[0104] It should be understood that one or more of the above embodiments or examples may be combined in a suitable manner.
