[0001] Cross Reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 202411252344.1, filed on September 6, 2024, entitled “A display panel and a display device”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of display, and in particular, to a display panel and a display device. BACKGROUND

[0004] In the display technology, especially in the design of portable devices such as smart phones, tablets, etc., narrow frame and narrow step are a popular feature because it can maximize the screen area while keeping the overall size of the device unchanged or only slightly increased.

[0005] The existing step area of the display panel includes a circuit area, a packaging area and a binding area arranged in sequence. The existing circuit area is provided with an electrostatic protection circuit. In the case of limited position, the electrostatic protection circuit needs to be arranged at the middle position of the step area. At this time, in order to provide high-level voltage (VGH) and low-level voltage (VGL) for the electrostatic protection circuit, the VGH signal line and the VGL signal line need to cross the step area, so as to lead out the line at the middle position and connect with the electrostatic protection circuit. At this time, the VGH signal line and the VGL signal line will occupy part of the step area, thereby increasing the width of the step area.

[0006] In order to reduce the width of the step area, in the existing design, the width of the packaging area or the height of the binding area is compressed to achieve it. However, the packaging strength of the packaging area will be reduced accordingly, or the reliability risk of the binding area will be increased. However, customers have higher and higher demands for narrow frame and narrow step of the display panel. Under the premise of meeting the performance of the product, it is necessary to further compress the step, and a display panel with good performance and narrow step is urgently needed to solve the above problems.

[0048] Features and exemplary embodiments of various aspects of the present application will be described in detail below. Numerous specific details will be disclosed in the following detailed description of the embodiments in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some or all of these specific details. The description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application. The present application is not limited to any particular configuration and algorithm disclosed below, but covers any modifications, alternatives, and improvements of elements, components, and algorithms without departing from the spirit of the present application. In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessary obscuring of the present application.

[0049] As described in the section of the background art, the demand of the customers for narrow frame and narrow step of the display panel is increasing, and it is necessary to further compress the step under the premise of meeting the product performance, and a display panel with good performance and narrow step is needed to solve the above problems.

[0050] Therefore, the display panel provided in the embodiments of the present application is shown in FIG. 1, which comprises a substrate 1, the substrate 1 comprising a display area 100 and a step area 200 located at one side of the display area 100; wherein the step area 200 comprises an electrostatic protection circuit 201 located at one side of the display area 100, and a packaging area 202 located at a side of the electrostatic protection circuit 201 away from the display area 100, as shown in FIG. 2, the display area 100 is used to form a display matrix, the display matrix comprising a plurality of light emitting elements 110 arranged in an array, and the packaging area 202 is used to form a packaging layer 210.

[0051] Specifically, as shown in FIG. 2, the light emitting element 110 comprises an anode 111, a cathode 113 and a light emitting layer 112 located between the anode 111 and the cathode 113, and optionally, the display panel further comprises a pixel circuit corresponding to the light emitting element one by one and electrically connected with the anode 111, the pixel circuit being controlled by a display control signal to control the light emitting state of the light emitting element, so as to control the display state of the display panel.

[0052] It should be noted that, in the embodiments, as shown in FIG. 1, the step area 200 further comprises at least one signal line 10 and at least one signal connection line 20, one end of the signal connection line 20 being electrically connected with the signal line 10, a second end of the signal connection line 20 being electrically connected with the electrostatic protection circuit 201, and at least part of the signal connection line 20 being located in the packaging area 202, so that by means of the projection of the signal connection line 20 on the substrate 1 and the projection of the packaging area 202 on the substrate 1 at least partially overlapping, the total width occupied by the signal connection line 20 and the packaging area 202 is reduced on the basis of the signal connection line 20 and the packaging area 202 being arranged at the same time, specifically, the width of the part of the signal connection line 20 located in the packaging area is reduced, and thus the width of the step area 200 is reduced, so as to realize a display panel with a narrow step.

[0053] Moreover, with the increasing demand of customers for narrow frame and narrow step of the display panel, more and more display panels adopt arc corners at present to reduce the frame area of the four corners of the display panel, and in the embodiments, the electrostatic protection circuit is located between the packaging area and the display area, and thus does not occupy the corner area of the frame area of the display panel, which is beneficial to further realize the narrow frame of the display panel, so that the corners of the display panel can adopt arc corners.

[0054] Specifically, in one embodiment of the present application, the packaging area includes a first side facing the display area and a second side facing away from the display area, and a third side and a fourth side oppositely arranged and connecting the first side and the second side. Optionally, in one embodiment of the present application, continuing as shown in FIG. 1, the signal connection line 20 penetrates the packaging area 202 from the first side and penetrates out of the packaging area 202 from the second side, that is, the signal connection line 20 penetrates the packaging area 202 in a direction parallel to the display area 100 to the packaging area 202, but the present application does not limit this, and in other embodiments of the present application, the signal connection line can also penetrate the packaging area from the first side or the second side and penetrate out of the packaging area from the third side or the fourth side, thereby partially penetrating the packaging area, depending on the specific circumstances.

[0055] In the following, the display panel provided by the embodiments of the present application will be described with the signal connection line penetrating the packaging area from the first side and penetrating out of the packaging area from the second side, that is, the signal connection line penetrates the packaging area in a direction parallel to the display area to the packaging area.

[0056] Optionally, in one embodiment of the present application, continuing as shown in FIG. 1, the signal connection line 20 includes a connection line main body part 21 extending in a first direction X, and a first extension part 22 and a second extension part 23 extending in a second direction Y, both ends of the first extension part 22 are electrically connected to the electrostatic protection circuit 201 and one end of the connection line main body part 21 respectively, both ends of the second extension part 23 are electrically connected to the other end of the connection line main body part 21 and the signal line 10 respectively, wherein the step area 200 is located on one side of the display area 100 in the second direction Y, and the first direction X and the second direction Y intersect. Optionally, the first direction X and the second direction Y are perpendicular, but the present application does not limit this, depending on the specific circumstances. It should be noted that in the present embodiment, the connection line main body part is at least partially located in the packaging area, thereby reducing the total width occupied by the signal connection line and the packaging area by setting the projection of the connection line main body part on the substrate and the projection of the packaging area on the substrate at least partially overlapping, based on the simultaneous setting of the signal connection line and the packaging area. Specifically, the width of the part of the connection line main body part located in the packaging area is reduced, thereby reducing the width of the step area, realizing a narrow step display panel.

[0057] Specifically, in one embodiment of the present application, as shown in FIG. 3 and FIG. 4, the connection line body part 21 is partially located in the packaging area 202, that is, the connection line body part 21 includes a part located in the packaging area 202 and a part located on one side of the packaging area 202. It should be noted that in this embodiment, the connection line body part 21 can overlap the first side edge 2021 of the packaging area 202, as shown in FIG. 3, in which the connection line body part 21 includes a part located in the packaging area 202 and a part located on the side of the packaging area 202 facing the display area 100, or overlap the second side edge 2022 of the packaging area 202, as shown in FIG. 4, in which the connection line body part 21 includes a part located in the packaging area 202 and a part located on the side of the packaging area 202 away from the display area 100, and the present application does not limit this. As long as the connection line body part is partially located in the packaging area, so as to reduce the total width occupied by the signal connection line and the packaging area by setting the projection of the connection line body part on the substrate to overlap the projection of the packaging area on the substrate, specifically, the width of the part of the connection line body part located in the packaging area is reduced, and then the width of the step area is reduced, thereby realizing a narrow-step display panel.

[0058] In another embodiment of the present application, as shown in FIG. 1, the connection line body part 21 is located in the packaging area 202, that is, the projection of the connection line body part 21 on the substrate 1 is located in the projection range of the packaging area 202 on the substrate 1, so as to maximize the overlapping area of the connection line body part 21 and the packaging area 202, thereby minimizing the total width occupied by the signal connection line 20 and the packaging area 202, specifically, the width of the connection line body part 21 is reduced, and then the width of the step area 200 is reduced, thereby realizing a narrow-step display panel.

[0059] It should be noted that in any of the above embodiments, the width of the connection line body part 21 in the second direction Y can be different from the width of the first extension part 22 in the first direction X, as shown in FIG. 5, or the same as the width of the first extension part 22 in the first direction X, as shown in FIG. 4.

[0060] Optionally, in one embodiment of the present application, as shown in FIG. 5, the width HZ1 of the connection line body part 21 in the second direction Y is greater than the width HZ11 of the first extension part 22 in the first direction X, that is, HZ1≥HZ11, so as to set the connection line body part 21 to have a larger width, so that the connection line body part 21 can act as a packing for the packaging area, thereby improving the light reflection effect and the curing effect of the packaging layer. At the same time, by setting the first extension part 22 to have a smaller width, the first extension part 22 occupies less space in the first direction X of the step area, which is conducive to the wiring design of the step area, but the present application does not limit this, and the specific design is determined according to the situation.

[0061] Similarly, as shown in FIG. 5, the width HZ1 of the connection line body part 21 in the second direction Y is greater than the width HZ12 of the second extension part 23 in the first direction X, i.e. HZ1≥HZ12, so that by setting the connection line body part 21 to have a greater width, the connection line body part 21 can serve as a pad for the packaging area, improving the light reflection effect when the packaging layer of the packaging area is formed and the effect of curing the packaging layer. Meanwhile, by setting the second extension part 23 to have a smaller width, the second extension part 23 occupies less space in the first direction X of the stepped area, which is conducive to the wiring design of the stepped area, but the present application does not limit this, which is determined according to the specific situation.

[0062] In another embodiment of the present application, as shown in FIG. 5, the width HZ1 of the connection line body part 21 in the second direction Y is greater than the width HZ11 of the first extension part 22 in the first direction X, and the width HZ1 of the connection line body part 21 in the second direction Y is greater than the width HZ12 of the second extension part 23 in the first direction X, i.e. HZ1≥HZ11 and HZ1≥HZ12, so that by setting the connection line body part 21 to have a greater width, the connection line body part 21 can serve as a pad for the packaging area, improving the light reflection effect when the packaging layer of the packaging area is formed and the effect of curing the packaging layer. Meanwhile, by setting the first extension part 22 and the second extension part 23 to have a smaller width, the first extension part 22 and the second extension part 23 occupy less space in the first direction X of the stepped area, which is conducive to the wiring design of the stepped area, but the present application does not limit this, which is determined according to the specific situation.

[0063] It should be noted that in the above embodiments, the width of the first extension part in the first direction and the width of the second extension part in the first direction can be the same or different, and the present application does not limit this, which is determined according to the specific situation.

[0064] It should also be noted that in the above embodiments, the width of the connection line body part 21 in the second direction Y at each position in the first direction X can be the same, as shown in FIG. 5, or not completely the same, as shown in FIG. 6. For example, the connection line body part 21 includes a plurality of connection line body parts connected in sequence, the width of each connection line body part in the second direction can be the same or different, and the projection shape of each connection line body part on the substrate can be the same or different. In addition, the projection of each connection line body part on the substrate can be on a straight line or not on a straight line, and the present application does not limit this, which is determined according to the specific situation.

[0065] Similarly, the width of each position of the first extension portion 22 in the second direction Y in the first direction X can be the same, as shown in FIG. 5, or can not be completely the same, as shown in FIG. 7. For example, the first extension portion 22 can include a plurality of first extension sub-portions connected in sequence in the second direction Y. The width of each first extension sub-portion in the first direction X can be the same or can not be completely the same. The projection shape of each first extension sub-portion on the substrate can be the same or can be different. In addition, the projection of each first extension sub-portion on the substrate can be on a straight line, or can not be on a straight line. For example, the projection shape of the first extension portion on the substrate can be a straight line, or can be a broken line. The present application does not limit this, and the specific implementation is determined according to the situation.

[0066] Similarly, the width of each position of the first extension portion 22 in the second direction Y in the first direction X can be the same, as shown in FIG. 5, or can not be completely the same, as shown in FIG. 7. For example, the first extension portion 22 can include a plurality of first extension sub-portions connected in sequence in the second direction Y. The width of each first extension sub-portion in the first direction X can be the same or can not be completely the same. The projection shape of each first extension sub-portion on the substrate can be the same or can be different. In addition, the projection of each first extension sub-portion on the substrate can be on a straight line, or can not be on a straight line. For example, the projection shape of the first extension portion on the substrate can be a straight line, or can be a broken line. The present application does not limit this, and the specific implementation is determined according to the situation.

[0067] In any of the above embodiments, in an embodiment of the present application, as shown in FIG. 8, the signal line includes a first signal line 11 and a second signal line 12, and the signal connection line includes a first signal connection line 24 and a second signal connection line 25. The width of the connection line main portion of the first signal connection line 24 in the second direction Y and the width of the connection line main portion of the second signal connection line 25 in the second direction Y satisfy the same condition. This improves the consistency of the connection line main portion of the first signal connection line 24 and the connection line main portion of the second signal connection line 25 when they are manufactured. At the same time, it improves the consistency of the reflection effect and the curing effect of the area where the connection line main portion of the first signal connection line 24 and the connection line main portion of the second signal connection line 25 are located when the packaging layer in the packaging area is formed.

[0068] It should be noted that, in the present embodiment, the condition that the width of the connection line body portion of the first signal connection line 24 in the second direction Y and the width of the connection line body portion of the second signal connection line 25 in the second direction Y are the same includes that the width of the connection line body portion of the first signal connection line 24 in the second direction Y and the width of the connection line body portion of the second signal connection line 25 in the second direction Y are substantially the same, i.e., the same within an error allowable range, and the present application does not limit the same, which is determined according to the actual situation.

[0073] In another embodiment of the present application, as shown in FIG. 10, the high-level signal connection line 26 enters the packaging area 202 from the second side edge 2022 of the packaging area 202, and exits the packaging area 202 from the first side edge 2021 of the packaging area 202, thereby realizing the electrical connection between the high-level signal line 13 and the electrostatic protection circuit 201; the low-level signal connection line 27 enters the packaging area 202 from the first side edge 2021 of the packaging area 202, extends to the lower side of the electrostatic protection circuit 201 in the packaging area 202, and then exits the packaging area 202 from the first side edge 2021 of the packaging area 202, thereby realizing the electrical connection between the low-level signal line 14 and the electrostatic protection circuit 201, and the width of the low-level signal connection line 27 in the packaging area 202 is saved.

[0074] In another embodiment of the present application, as shown in FIG. 11, the high-level signal connection line 26 enters the packaging area 202 from the first side edge 2021 of the packaging area 202, extends to the lower side of the electrostatic protection circuit 201 in the packaging area 202, and then exits the packaging area 202 from the first side edge 2021 of the packaging area 202, thereby realizing the electrical connection between the high-level signal line 13 and the electrostatic protection circuit 201, and the width of the high-level signal connection line 26 in the packaging area 202 is saved; the low-level signal connection line 27 enters the packaging area 202 from the second side edge 2022 of the packaging area 202, and exits the packaging area 202 from the first side edge 2021 of the packaging area 202, thereby realizing the electrical connection between the low-level signal line 14 and the electrostatic protection circuit 201.

[0075] In other embodiments of the present application, as shown in FIG. 12, the high-level signal connection line 26 enters the packaging area 202 from the first side edge 2021 of the packaging area 202, extends to the lower side of the electrostatic protection circuit 201 in the packaging area 202, and then exits the packaging area 202 from the first side edge 2021 of the packaging area 202, thereby achieving the electrical connection between the high-level signal line 13 and the electrostatic protection circuit 201, while saving the width of the high-level signal connection line 26 in the packaging area 202; the low-level signal connection line 27 enters the packaging area 202 from the first side edge 2021 of the packaging area 202, extends to the lower side of the electrostatic protection circuit 201 in the packaging area 202, and then exits the packaging area 202 from the first side edge 2021 of the packaging area 202, thereby achieving the electrical connection between the low-level signal line 14 and the electrostatic protection circuit 201, while saving the width of the low-level signal connection line 27 in the packaging area 202.
