Description

Technical Field

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

[0002] Organic Light Emitting Diode (OLED) and flat panel display devices based on technologies such as Light Emitting Diode (LED) have been widely used in various consumer electronic products such as mobile phones, televisions, laptops, desktop computers, etc. due to their advantages such as high image quality, power saving, thin body and wide application range, becoming the mainstream in display devices.

[0003] In the process of preparing traditional display panels, the graphicization of luminous pixels is usually achieved through a fine metal mask (FMM).

When preparing the light-emitting layer 300, the light-emitting layer 300 has a large drop at the edge of the isolation structure 200, which is difficult to connect, and thus breaks. The light-emitting layer 300 breaks to form light-emitting units 310 that are disconnected from each other and located in the isolation opening 240, thereby reducing the crosstalk of carriers in the light-emitting layer 300 and improving the display effect of the display panel 10. In addition, the light-emitting unit 310 can be prepared without using a precision mask plate, which can reduce the development and use of precision masks and reduce the preparation cost.

The size of the light-transmitting opening 250 can be set larger, so that the transmittance of the display panel 10 can be improved while ensuring the aperture ratio of the display panel 10, so as to improve the display effect of the display panel 10, thereby improving the performance of the OLED display product.

[0086] There are many ways to set the substrate 100. For example, the substrate 100 may include a substrate and an array substrate arranged on the substrate. Alternatively, the substrate 100 is the substrate. Alternatively, the substrate 100 includes a buffer layer and a support plate on a side away from the substrate.

[0090] See also Figure 4 , Figure 4 FIG. 4 is a partial top view of a display panel in yet another embodiment.

[0103] In these optional embodiments, the first spacing L1 is greater than or equal to 19 μm, which can improve the problem that the light-transmitting opening 250 provided between the first light-emitting unit 311 and the second light-emitting unit 312 on one side in the first direction X is too small, and the transmittance of the display panel 10 is too small. The first spacing L1 is less than or equal to 31 μm, which can improve the problem that the pixel density (Pixels Per Inch, PPI) of the display panel 10 is reduced due to the first spacing L1 being too large, resulting in the distance between the first light-emitting unit 311 and the second light-emitting unit 312 on one side in the first direction X being too large.

The first sub-width D1 is less than or equal to 26 μm, which can improve the problem that the pixel density (Pixels Per Inch, PPI) of the display panel 10 is reduced due to the first sub-width D1 being too large, resulting in an excessive distance between the first light-emitting unit 311 and the second light-emitting unit 312 on one side in the first direction X.

[0111] In some optional embodiments, the second sub-width D2 is 3 μm to 8 μm. For example, the second sub-width D2 is 3 μm, 5 μm, 6 μm, or 8 μm.

The second sub-width D2 is less than or equal to 8 μm, which can improve the problem that the first sub-width D1 is too small while ensuring the aperture ratio, the size of the light-transmitting opening 250 set between the first light-emitting unit 311 and the second light-emitting unit 312 on one side in the first direction X is too small, and the transmittance of the display panel 10 is low.

[0116] In these optional embodiments, the width of the first opening 251 in the first direction X is greater than or equal to 10 μm, which can improve the problem that the size of the first opening 251 is too small and the light transmittance of the display panel 10 is reduced due to the width of the first opening 251 in the first direction X being too small. The width of the first opening 251 in the first direction X is less than or equal to 20 μm, which can improve the problem that the first interval L1 needs to be set too large due to the width of the first opening 251 in the first direction X being too large, the distance between the first light-emitting unit 311 and the second light-emitting unit 312 on one side in the first direction X being too large, and the pixel density (Pixels Per Inch, PPI) of the display panel 10 being reduced.

[0167] In these optional embodiments, light-transmitting openings 250 are provided on both sides of the light-emitting unit 310 in the first direction X. Providing a greater number of light-transmitting openings 250 can further increase the transmittance of the display panel 10 .

[0168] Optionally, the first light-emitting unit 311 and the second light-emitting unit 312 are provided with a light-transmitting opening 250 on one side in the first direction X, and the third light-emitting unit 313 is provided with a light-transmitting opening 250 on both sides in the first direction X, or the first light-emitting unit 311, the second light-emitting unit 312 and the third light-emitting unit 313 are provided with a light-transmitting opening 250 on both sides in the first direction X.

[0169] like Figure 1 and Figure 2 As shown, in some optional embodiments, the display panel 10 further includes: a pixel definition layer 500, located on one side of the substrate 100, the pixel definition layer 500 includes a pixel defining portion 510 and a pixel opening 520 formed by the pixel defining portion 510, and the pixel opening 520 is connected to the isolation opening 240.

[0170] In these optional embodiments, the pixel defining portion 510 of the pixel defining layer 500 encloses a pixel opening 520 to set the light emitting unit 310 and realize normal light emission of the light emitting unit 310. In addition, the pixel defining portion 510 defines the setting area of ​​each light emitting unit 310 to reduce the cross-color defect between each light emitting unit 310.

[0171] Optionally, the distance between the pixel openings 520 where at least some of the light-emitting units 310 are located and the pixel openings 520 where the light-emitting units 310 adjacent on one side in the first direction X are located is a first distance d1, and the distance between the pixel openings 520 where the light-emitting units 310 adjacent on the other side in the first direction X are a second distance d2, and the first distance d1 is greater than the second distance d2, that is, the distance between the pixel openings 520 where the light-emitting units 310 are located and the pixel openings 520 where the light-emitting units 310 adjacent on one side in the first direction X is greater than the distance between the pixel openings 520 where the light-emitting units 310 are located and the pixel openings 520 where the light-emitting units 310 adjacent on the other side in the first direction X.

[0172] In some optional embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 located on a side of the first layer 210 facing away from the substrate 100 , and an orthographic projection of the first layer 210 on the substrate 100 is located within an orthographic projection of the second layer 220 on the substrate 100 .

[0173] In these optional embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 located on the side of the first layer 210 facing away from the substrate 100. The first layer 210 and the second layer 220 are stacked to form the isolation structure 200. The orthographic projection of the first layer 210 arranged close to the substrate 100 on the substrate 100 is located within the orthographic projection of the second layer 220 on the substrate 100. The area of ​​the second layer 220 is larger than the area of ​​the first layer 210. The second layer 220 covers the surface of the first layer 210 close to the second layer 220. At this time, the first layer 210 is recessed relative to the second layer 220 in a direction away from the isolation opening 240. When preparing the light-emitting layer 300, a large step is generated at the edge of the isolation structure 200 of the light-emitting layer 300, and the first layer 210 is concave relative to the second layer 220. The light-emitting layer 300 is difficult to connect at the edge of the isolation structure 200, and thus breaks. The light-emitting layer 300 breaks to form light-emitting units 310 that are disconnected from each other, thereby reducing crosstalk of carriers in the light-emitting layer 300 and improving the display effect of the display panel 10. In addition, the light-emitting unit 310 can be prepared without using a precision mask plate, which can reduce the development and use of precision masks and reduce preparation costs.

[0174] Optionally, the first layer 210 includes a conductive material, for example, the first layer 210 includes a non-metallic conductive material or a metallic conductive material.

[0175] In some optional embodiments, the second layer 220 includes a conductive material or an insulating material.

[0176] In these optional embodiments, the second layer 220 includes a conductive material, for example, the second layer 220 includes a non-metallic conductive material or a metallic conductive material. When the second layer 220 is a non-metallic conductive material or an insulating material, the second layer 220 is difficult to be etched during wet etching of the first layer 210 using an etching solution, so that the first layer 210 is more easily concavely arranged relative to the second layer 220.

[0177] In some optional embodiments, both the first layer 210 and the second layer 220 include metal materials, and the materials of the first layer 210 and the second layer 220 are different.

[0178] In these optional embodiments, when both the first layer 210 and the second layer 220 are made of metal materials, the first layer 210 may be wet-etched with an etching solution, and the etching rate of the second layer 220 may be set to be lower than the etching rate of the first layer 210 by setting the etching solution. Since the etching rate of the first layer 210 is relatively high, when the etching solution is used for wet etching, even if the second layer 220 is etched to a certain extent, the first layer 210 is etched faster, so that the first layer 210 is set concave relative to the second layer 220.

[0179] See also Fig.14 , Fig.14 is a partial cross-sectional view of a display panel in yet another embodiment.

[0180] like Fig.14 As shown, in some optional embodiments, the isolation structure 200 further includes a third layer 230 located on the side of the first layer 210 facing the substrate 100 , and the orthographic projection of the first layer 210 on the substrate 100 is located within the orthographic projection of the third layer 230 on the substrate 100 .

[0181] Due to the etching, the waste generated by the etching is easy to enter other positions of the display panel 10, thereby causing adverse effects. After the third layer 230 is set, the first layer 210 can be well attached to the third layer 230, and the generated etching waste falls on the third layer 230, which is easy to clean.

[0182] Optionally, the display panel 10 further includes a first electrode 530 located between the substrate 100 and the pixel definition layer 500 , and at least a portion of the first electrode 530 is exposed by the pixel opening 520 to serve as an electrode of the light emitting unit 310 .

[0183] In some optional embodiments, the display panel 10 further includes: a second electrode layer 400 located on a side of the light-emitting layer 300 facing away from the substrate 100 , the second electrode layer 400 including a second electrode 410 located in the isolation opening 240 , and the second electrode 410 is electrically connected to the isolation structure 200 .

[0184] In these optional embodiments, the isolation structure 200 separates the second electrode layer 400 to form mutually spaced second electrodes 410, and the mutually spaced second electrodes 410 are electrically connected through the isolation structure 200 to form a whole-surface electrode, thereby ensuring the normal light emission of the light-emitting unit 310. One of the second electrode 410 and the first electrode 530 serves as the anode of the light-emitting unit 310, and the other serves as the cathode of the light-emitting unit 310. The embodiment of the present application is described by taking the second electrode 410 as the cathode of the light-emitting unit 310 and the first electrode 530 as the anode of the light-emitting unit 310 as an example.

[0185] In some optional embodiments, the orthographic projection of the light emitting unit 310 on the substrate 100 is located within the orthographic projection of the second electrode 410 on the substrate 100 .

[0186] In these optional embodiments, the orthographic projection of the light-emitting unit 310 on the substrate 100 is located within the orthographic projection of the second electrode 410 on the substrate 100, that is, the first electrode 530 is arranged to cover the light-emitting unit 310 to serve as an electrode of the light-emitting unit 310, thereby ensuring normal light emission of the light-emitting unit 310 and improving the display effect of the display panel 10.

[0187] Optionally, the light-emitting unit 310 and the isolation structure 200 are spaced apart, that is, the light-emitting units 310 are spaced apart from each other, thereby reducing the crosstalk of carriers between the light-emitting units 310 and improving the cross-color problem of the light-emitting units 310.

[0188] Optionally, the light emitting layer 300 includes an electron injection layer (EIL), an electron transport layer (ETL), a light emitting material layer, a hole injection layer (HIL) and a hole transport layer (HTL). The light emitting unit 310 includes only at least one of the electron injection layer (EIL), the electron transport layer (ETL), the light emitting material layer, the hole injection layer (HIL) and the hole transport layer (HTL), and does not include structures such as the first electrode 530 and the second electrode 410.

[0189] The second aspect of the present application provides a display panel 10, which includes: a substrate 100; an isolation structure 200, located on one side of the substrate 100, the isolation structure 200 encloses a plurality of isolation openings 240 and a plurality of light-transmitting openings 250; a light-emitting layer 300, located on one side of the substrate 100, the light-emitting layer 300 includes light-emitting units 310 located corresponding to the isolation openings 240, at least part of the light-emitting units 310 include a first edge 314 and a second edge 315 arranged opposite to each other in a first direction X, the light-transmitting opening 250 includes a third edge 253 and a fourth edge 254 arranged opposite to each other in the first direction X, and the first edge 314 and / or the second edge 315 are arranged parallel to the third edge 253.

[0190] According to the display panel 10 of the embodiment of the present application, the display panel 10 includes a substrate 100, an isolation structure 200 and a light-emitting layer 300. When preparing the light-emitting layer 300, the light-emitting layer 300 has a large drop at the edge of the isolation structure 200, which is difficult to connect, and thus breaks. The light-emitting layer 300 breaks to form light-emitting units 310 that are disconnected from each other and located in the isolation opening 240, thereby reducing the crosstalk of carriers in the light-emitting layer 300 and improving the display effect of the display panel 10. In addition, the light-emitting unit 310 can be prepared without using a precision mask plate, which can reduce the development and use of precision masks and reduce the preparation cost. The first side 314 is parallel to the third side 253, or the second side 315 is parallel to the third side 253, or both the first side 314 and the second side 315 are parallel to the third side 253. When the third side 253 of the light-transmitting opening 250 is parallel to the first side 314 and / or the second side 315 of the light-emitting unit 310, the size of the light-transmitting opening 250 can be set larger, thereby maximizing the size of the light-transmitting opening 250, thereby improving the transmittance of the display panel 10 while ensuring the aperture ratio of the display panel 10.
