[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0058] In the encapsulation structure of flexible OLED displays, the organic encapsulation structure is typically fabricated using inkjet printing (IJP) technology. Because the ink in the organic encapsulation structure is fluid, preventing ink overflow is crucial to ensuring IJP yield. Currently, to prevent ink overflow, the organic film layer inside the dam is usually removed to create a leveling zone.

[0059] Through long-term research, the inventors discovered that because the organic film layer in the leveling area is removed, the underlying metal layer is exposed. When evaporating the cathode, in order to avoid the cathode overlapping with the underlying metal layer, it is necessary to ensure that there is a sufficient distance between the cathode and the leveling area. This results in an excessively wide bezel that cannot be compressed, making it difficult to meet consumers' growing demand for narrower bezels in products.

[0060] Based on this, this application provides a display panel solution to solve the above problems.

[0061] Please refer to Figure 1 and 2 As shown, a display panel 100 provided in an embodiment of this application has a display area 101 and a non-display area 102, with the non-display area 102 located on at least one side of the display area 101; the display panel 100 includes a substrate 1, a fourth metal layer 2, an organic layer 3, a first dam 4, and a second electrode layer 51.

[0062] The fourth metal layer 2 is located on one side of the substrate 1, the organic layer 3 is located on the side of the fourth metal layer 2 away from the substrate 1, the first dam 4 is located on the side of the fourth metal layer 2 away from the substrate 1 and located in the non-display area 102, and the second electrode layer 51 is located on the side of the organic layer 3 away from the substrate 1; wherein, the organic layer 3 is continuously disposed between the first dam 4 and the display area 101.

[0063] The display panel 100 provided in this embodiment provides an organic layer 3 on the side of the fourth metal layer 2 away from the substrate 1, and the organic layer 3 is continuously disposed between the first dam 4 and the display area 101. The organic layer 3 covers the lower fourth metal layer 2, thereby preventing a short circuit between the second electrode layer 51 and the fourth metal layer 2 and achieving shielding of the second electrode layer 51.

[0064] Meanwhile, since there is no need to worry about a short circuit between the second electrode layer 51 and the fourth metal layer 2, the bezel width can be reduced by compressing the distance between the first dam 4 and the display area 101, which is beneficial to achieving a narrower bezel and improving the performance of the display panel 100.

[0065] Specifically, refer to Figure 2 As shown, the film structure in the non-display area 102 is shown. The display area 101 can be located to its left. In order to prevent the shadow distance during the evaporation of the second electrode layer 51 from affecting the normal display of the display area 101, the distance a from the boundary of the second electrode layer 51 to the display area 101 needs to be greater than a preset value. At the same time, since there is no need to worry about a short circuit between the second electrode layer 51 and the fourth metal layer 2, the bezel width can be reduced by compressing the distance between the boundary of the second electrode layer 51 and the first dam 4.

[0066] The shadow distance refers to the size of the shadow area formed on the substrate by the vapor deposition material during the vapor deposition process, due to factors such as the position and angle of the vapor deposition source and the mask. Specifically, when using a point vapor deposition source, if the vapor deposition source is close to the substrate (smaller TS distance), the material utilization rate is high, but the film uniformity is poor and the shadow distance is large; while when the vapor deposition source is far from the substrate (larger TS distance), the film uniformity is better and the shadow distance is smaller, but the material utilization rate is lower.

[0067] Optionally, the substrate is a flexible substrate to achieve a flexible display. For example, PI (polyimide), or a three-layer structure of PI + buffer layer + PI.

[0068] Reference Figure 3 As shown, in one embodiment, the display panel 100 further includes a second planarization layer 31, which is located on the side of the fourth metal layer 2 away from the substrate 1. The second planarization layer 31 serves to plan the surface of the fourth metal layer 2 and also acts as an insulator.

[0069] Preferably, the organic layer 3 includes a second planarization layer 31. Specifically, the second planarization layer 31 is continuously disposed between the first dam 4 and the display area 101, and the fourth metal layer 2 below is covered by the second planarization layer 31 to avoid short circuit between the second electrode layer 51 and the fourth metal layer 2, thereby achieving shielding of the second electrode layer 51.

[0070] Preferably, the orthographic projection of the first dam 4 on the substrate 1 overlaps with the orthographic projection of the second planarization layer 31 on the substrate 1, which is equivalent to further compressing the first dam 4 towards the display area 101, which helps to further reduce the bezel width. At the same time, the second planarization layer 31 is used to raise the first dam 4, thereby improving the performance of the first dam 4.

[0071] Please continue to refer to Figure 3 As shown, in one embodiment, the display panel 100 includes a pixel defining layer 32, which is located on the side of the fourth metal layer 2 away from the substrate 1. The pixel defining layer 32 clearly delineates the area of ​​each pixel, ensuring the accurate light-emitting area of ​​each pixel, thereby achieving precise image display. Taking the common RGB pixel arrangement as an example, the pixel defining layer 32 precisely defines the position and size of the red, green, and blue sub-pixels, arranging them in a specific way to form a complete pixel, allowing the screen to present a clear and detailed image. The pixel defining layer 32 is partially located in the display area 101 and partially in the non-display area 102.

[0072] Preferably, the organic layer 3 includes a pixel defining layer 32. Specifically, the pixel defining layer 32 is continuously disposed between the first dam 4 and the display area 101, and the pixel defining layer 32 covers the lower fourth metal layer 2 to prevent short circuits between the second electrode layer 51 and the fourth metal layer 2, thereby shielding the second electrode layer 51.

[0073] Preferably, the orthographic projection of the first dam 4 on the substrate 1 overlaps with the orthographic projection of the pixel defining layer 32 on the substrate 1, which is equivalent to further compressing the first dam 4 towards the display area 101, which helps to further reduce the bezel width. At the same time, the pixel defining layer 32 is used to raise the first dam 4, thereby improving the performance of the first dam 4.

[0074] Please continue to refer to Figure 3 As shown, in one embodiment, the display panel 100 includes a second planarization layer 31 and a pixel defining layer 32. The second planarization layer 31 is located on the side of the fourth metal layer 2 away from the substrate 1, and the pixel defining layer 32 is located on the side of the second planarization layer 31 away from the substrate 1.

[0075] Preferably, the organic layer 3 includes a second planarization layer 31 and / or a pixel defining layer 32. Specifically, the second planarization layer 31 or the pixel defining layer 32 is continuously disposed between the first dam 4 and the display area 101, and the fourth metal layer 2 below is covered by the second planarization layer 31 or the pixel defining layer 32. Alternatively, the second planarization layer 31 and the pixel defining layer 32 can be continuously disposed simultaneously between the first dam 4 and the display area 101, with both the second planarization layer 31 and the pixel defining layer 32 covering the fourth metal layer 2 below, thereby improving the shielding effect.

[0076] Preferably, the orthographic projection of the first dam 4 on the substrate 1 overlaps with the orthographic projection of the second planarization layer 31 on the substrate 1, and the orthographic projection of the first dam 4 on the substrate 1 overlaps with the orthographic projection of the pixel defining layer 32 on the substrate 1. This is equivalent to further compressing the first dam 4 towards the display area 101, which helps to further reduce the bezel width. At the same time, the second planarization layer 31 and the pixel defining layer 32 are used to raise the first dam 4, thereby improving the performance of the first dam 4.

[0077] Reference Figure 4 As shown, in one embodiment, the organic layer 3 includes a recessed region 33, the orthographic projection of which onto the substrate 1 lies between the orthographic projection of the first dam 4 onto the substrate 1 and the orthographic projection of the second electrode layer 51 onto the substrate 1. The recessed region 33 facilitates the leveling of the organic encapsulation material, enabling monitoring of the leveling of the organic encapsulation material.

[0078] Specifically, the second planarization layer 31 or pixel definition layer 32 is not provided in the recessed area 33 to achieve the recessed effect. Alternatively, the second planarization layer 31 and / or pixel definition layer 32 are partially etched to achieve the recessed effect.

[0079] Reference Figure 5 As shown, in one embodiment, the display panel 100 further includes a first electrode layer 52 and a light-emitting layer 53, wherein the first electrode layer 52, the light-emitting layer 53, and the second electrode layer 51 are sequentially stacked along a direction away from the substrate 1.

By applying different voltages to the first electrode layer 52 and the second electrode layer 51, the light-emitting material in the light-emitting layer 53 emits light. Preferably, the first electrode layer 52 includes an anode layer, and the second electrode layer 51 includes a cathode layer.

[0080] Reference Figure 6 As shown, in one embodiment, the display panel 100 further includes an encapsulation layer 6, which is located on the side of the organic layer 3 and the second electrode layer 51 away from the substrate 1.

[0081] Preferably, the encapsulation layer 6 consists of a first encapsulation layer 61, a second encapsulation layer 62, and a third encapsulation layer 63 stacked sequentially along the direction away from the substrate 1, with three layers of encapsulation to ensure the encapsulation effect.

[0082] Preferably, the first encapsulation layer 61 and the third encapsulation layer 63 comprise inorganic materials, and the second encapsulation layer 62 comprises organic materials, achieving an inorganic-organic-inorganic three-layer encapsulation to ensure the encapsulation effect. The inorganic encapsulation can be prepared using chemical vapor deposition, which is beneficial for improving the density of the encapsulation layer and the encapsulation effect, while the organic encapsulation can be prepared using inkjet printing.

The first dam 4 blocks the organic encapsulation material of the second encapsulation layer 62 from overflowing into the inner side of the first dam 4.

[0084] Reference Figure 7 As shown, in one embodiment, the display panel 100 further includes a second dam 7, which is located on the side of the fourth metal layer 2 away from the substrate 1 and in the non-display area 102. The second dam 7 is located on the side of the first dam 4 away from the display area 101. The second dam 7 can further reduce the risk of overflow and improve the encapsulation effect.

[0085] Preferably, the orthographic projection of the organic layer 3 onto the substrate 1 overlaps with the second dam 7. The organic layer 3 is used to elevate the second dam 7, thereby improving its performance.

[0086] Reference Figure 8 As shown, in one embodiment, the display panel 100 further includes a third metal layer 8, which is located between the substrate 1 and the fourth metal layer 2.
