Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a display panel and display device. Background Technology

[0002] With the development of various technologies, the market demands increasingly higher standards for full-screen OLED displays, and the scope of special application scenarios is also expanding, with some requiring the addition of one or more OLED devices to achieve this. Existing OLED products use OLED devices with three primary colors (R, G, and B) to synthesize a white image. X OLED devices can be added to the RGB OLED base to form four-color pixel units, thereby improving the color gamut. X represents materials such as deep red / sky blue.

[0003] However, in existing four-color OLED panels, the spacers used to support the vapor deposition mask are usually placed between two adjacent sub-pixels in the column direction, which increases the spacing between the sub-pixels on the upper and lower sides of the spacers and reduces the aperture ratio of the OLED panel.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0025] It should be noted that, please refer to Figure 1 This is a top view structural diagram of the display panel of Comparative Examples 1 and 2 of this application. Figure 2 These are top view structural diagrams of the display panels of Comparative Examples 3 and 4 of this application.

[0026] exist Figure 1 and Figure 2 In the display panel, multiple pixel units U0 are included. Each pixel unit U0 includes a red sub-pixel R0, a green sub-pixel G0, a blue sub-pixel B0, and a fourth color sub-pixel X0. The color of the fourth color sub-pixel X0 is different from that of red, green, and blue. The multiple pixel units U0 are arranged along a first direction F1 and a second direction F2. The first direction F1 is perpendicular to the second direction F2.

[0027] Red sub-pixels R0 and fourth color sub-pixels X0 are arranged alternately along the first direction, green sub-pixels G0 and blue sub-pixels B0 are arranged alternately along the first direction F1, red sub-pixels and green sub-pixels are arranged alternately along the second direction F2, and fourth color sub-pixels and blue sub-pixels are arranged alternately along the second direction F2.

[0028] exist Figure 1 In the second direction F2, a spacer PS and a sub-pixel are alternately arranged. The difference is that the spacer PS in Comparative Example 1 is shorter, while the spacer PS in Comparative Example 2 is longer. Because the spacer PS is placed between the sub-pixels in the second direction F2, the spacing between two adjacent sub-pixels in the second direction F2 is larger, resulting in a larger aperture ratio loss.

[0029] exist Figure 2 In the first direction F1, a spacer PS and a sub-pixel are alternately arranged. The difference is that the spacer PS in Comparative Example 3 is shorter, while the spacer PS in Comparative Example 4 is longer. Because the spacer PS is arranged between the sub-pixels in the first direction F1, the distance between two adjacent sub-pixels in the first direction F1 is larger, resulting in a larger aperture ratio loss.

[0030] Based on this, this application provides a display panel 100, please refer to... Figure 3 and Figure 4 , Figure 3 This is a top view of the display panel 100 provided in an embodiment of this application. Figure 4 yes Figure 3 A schematic diagram of the cross-sectional structure along line C1C1.

[0031] Optionally, in some embodiments of this application, the display panel 100 includes a pixel circuit layer 11, an anode layer 12, a pixel definition layer 13, spacers 14, and a light-emitting layer 15.

[0032] Optionally, the pixel circuit layer 11 includes multiple pixel circuits. An anode layer 12 is disposed on the pixel circuit layer 11, and the anode layer 12 includes multiple anodes 12a. Each anode 12a is connected to a corresponding pixel circuit.

[0033] A pixel definition layer 13 is disposed on the pixel circuit layer 11 and covers the edge portion of the anode 12a. The pixel definition layer 13 has multiple pixel openings 13a. The pixel openings 13a expose the anode 12a.

[0034] Spacer 14 is disposed on pixel definition layer 13 and located outside pixel opening 13a. Emissive layer 15 covers pixel opening 13a.

[0035] Optionally, in some embodiments, the display panel 100 further includes a cathode and an encapsulation layer, which sequentially cover the side of the light-emitting layer 15 away from the pixel circuit layer 11.

[0036] Optionally, the material of the light-emitting layer 15 can be an organic material, such as Alq3, bis(2-methyl-8-hydroxyquinoline-N1,O8)-(1,1'-biphenyl-4-hydroxy)aluminum (BAlq), DPVBi, Almq3, or 3-tert-butyl-9,10-bis(2-naphthyl)anthracene (TBADN).

[0037] The material of the light-emitting layer 15 can also be an inorganic material, such as one or more selected from group IV semiconductor nanocrystals, group II-V semiconductor nanocrystals, group II-VI semiconductor nanocrystals, group IV-VI semiconductor nanocrystals, group III-V semiconductor nanocrystals, and group III-VI semiconductor nanocrystals. For example, it can be one or more selected from silicon quantum dots, germanium quantum dots, cadmium sulfide quantum dots, cadmium selenide quantum dots, cadmium telluride quantum dots, zinc selenide quantum dots, lead sulfide quantum dots, lead selenide quantum dots, indium phosphide quantum dots, indium arsenide quantum dots, and gallium nitride quantum dots.

[0038] Optionally, in some embodiments of this application, the light-emitting layer 15 includes a plurality of pixel units U1. Each pixel unit U1 includes four sub-pixels P1 of different colors. A portion of the sub-pixels P1 covers the pixel opening 13a. The plurality of pixel units U1 are arranged in a first direction F1. The plurality of pixel units U1 are also arranged in a second direction F2 intersecting the first direction F1.

[0039] For example, the first direction F1 is perpendicular to the second direction F2.

[0040] In the display panel 100 viewed from above, in two adjacent pixel units U1, in the second direction F2, two sub-pixels P1 of one pixel unit U1 and their corresponding pixel openings 13a, and two sub-pixels P1 of another pixel unit U1 and their corresponding pixel openings 13a are arranged adjacently to form a pixel group UP. The four sub-pixels P1 of the pixel group UP are of different colors.

[0041] Spacer 14 is disposed in the area of ​​pixel group UP, and the four sub-pixels P1 of pixel group UP are disposed around spacer 14. In pixel group UP, the four pixel openings 13a form a non-right-angle transition surface facing the sidewall 14a of spacer 14.

[0042] It is understood that in this embodiment, the four pixel openings 13a in the pixel group UP are beveled to form a non-right-angle transition surface, thereby freeing up space for the spacer 14, without increasing the spacing of the pixel openings 13a in the first direction F1 and the second direction F2. Simultaneously, based on the four-color sub-pixels P1 surrounding the spacer 14, the spacer 14 can also be used to support the mask 200 for depositing the four-color sub-pixels P1. Figure 5 As shown, in order to reduce the number of spacers 14, the two work together to increase the aperture ratio of the display panel 100.

[0043] Optionally, in some embodiments of this application, the pattern shape of the pixel opening 13a is a rectangle with chamfers, and the non-right-angle transition surface is the sidewall 14a surface at the chamfer. That is, the non-right-angle transition surface is an inclined plane.

[0044] Understandably, based on the support area requirements of the spacer 14 and the light-emitting area requirements of the sub-pixel P1, the dimensions of the two straight sides of the rectangular pixel opening 13a that are cut off can be between 2 micrometers and 5 micrometers, for example, 2 micrometers, 3 micrometers, 4 micrometers and 5 micrometers.

[0045] It should be noted that the second straight edges on the left and right sides of the pixel opening 13a extend along the second direction F2, and the first straight edges on the upper and lower sides of the pixel opening 13a extend along the first direction F1. The non-right-angle transition surface connects the first straight edge and the second straight edge.

[0046] Optionally, in some embodiments of this application, the non-right-angle transition surface may also be non-planar, such as an arc surface or an irregular surface. The irregular surface may be wavy, zigzag, etc., as long as the rectangular pixel opening 13a is cut to make room for the spacer 14.

[0047] Optionally, in some embodiments of this application, sub-pixel P1 includes a pixel portion p11 and an extension portion p12. The pixel portion p11 is disposed within the pixel opening 13a, and the extension portion p12 is connected to the outer periphery of the pixel portion p11 and extends around the circumferential direction of the pixel opening 13a. The extension portion p12 extends beyond the pixel opening 13a.

[0048] In the first direction F1 and the second direction F2 of pixel group UP, the outer extension p12 of two adjacent sub-pixels P1 are connected.

[0049] It should be noted that during the deposition of the light-emitting layer 15, in order to ensure that the light-emitting layer 15 covers the entire pixel opening 13a, the opening of the mask 200 needs to be relatively large and extend beyond the pixel opening 13a by a set distance. The set distance can be set according to the actual situation. Based on this, after deposition, the portion of sub-pixel P1 that extends beyond the pixel opening 13a is the epitaxial portion p12.

[0050] Optionally, the width of the extension p12 of each sub-pixel P1 is equal, that is, the set distance of the opening of each mask template 200 is equal.

[0051] It is understandable that the spacer 14 is set in the four pixel openings 13a in the pixel group UP, and the corners are beveled to make room, so as to reduce the distance between two adjacent pixel openings 13a, and connect the outer extensions p12 of two adjacent sub-pixels P1.

[0052] Optionally, in some embodiments of this application, the four sub-pixels P1 in the pixel group UP include a first sub-pixel R1, a second sub-pixel B1, a third sub-pixel G1, and a fourth sub-pixel X1. The first sub-pixel R1 and the second sub-pixel B1 are arranged along a first direction F1. The third sub-pixel G1 and the fourth sub-pixel X1 are arranged along the first direction F1. The first sub-pixel R1 and the third sub-pixel G1 are arranged along a second direction F2. The second sub-pixel B1 and the fourth sub-pixel X1 are arranged along the second direction F2.

[0053] Optionally, the first sub-pixel R1 is a red sub-pixel, the second sub-pixel B1 is a blue sub-pixel, the third sub-pixel G1 is a green sub-pixel, and the fourth sub-pixel X1 is a cyan sub-pixel. However, this is not limited to these options. For example, the fourth sub-pixel X1 could be a yellow sub-pixel, a white sub-pixel, a pink sub-pixel, or a purple sub-pixel. Or, the first sub-pixel R1 could be a green sub-pixel, the second sub-pixel B1 a blue sub-pixel, and the third sub-pixel G1 a red sub-pixel.

[0054] Optionally, in the first direction F1, the first sub-pixel R1 and the second sub-pixel B1 are arranged alternately, and the third sub-pixel G1 and the fourth sub-pixel X1 are arranged alternately. In the second direction F2, the first sub-pixel R1 and the third sub-pixel G1 are arranged alternately, and the second sub-pixel B1 and the fourth sub-pixel X1 are arranged alternately.

[0055] Specifically, in some embodiments of this application, in pixel group UP, in the first direction F1, the first sub-pixel R1 and the second sub-pixel B1 are connected, and the third sub-pixel G1 and the fourth sub-pixel X1 are connected; in the second direction F2, the first sub-pixel R1 and the third sub-pixel G1 are connected, and the second sub-pixel B1 and the fourth sub-pixel X1 are connected. Spacer 14 is located between the first sub-pixel R1 and the fourth sub-pixel X1 and between the second sub-pixel B1 and the third sub-pixel G1.

[0056] Optionally, in some embodiments of this application, the plurality of pixel openings 13a include a first pixel opening a1 corresponding to a first sub-pixel R1, a second pixel opening a2 corresponding to a second sub-pixel B1, a third pixel opening a3 corresponding to a third sub-pixel G1, and a fourth pixel opening a4 corresponding to a fourth sub-pixel X1.

[0057] In the first direction F1 of pixel group UP, the spacer 14 partially overlaps with the first pixel opening a1, the second pixel opening a2, the third pixel opening a3 and the fourth pixel opening a4, respectively.

[0058] It is understood that in the first direction F1, one end of the spacer 14 partially overlaps with the first pixel opening a1 and the second pixel opening a2, and the other end of the spacer 14 partially overlaps with the third pixel opening a3 and the fourth pixel opening a4, so as to save the area occupied by the spacer 14 in the second direction F2 and improve the aperture ratio of the display panel 100.

[0059] Optionally, in some embodiments of this application, in the second direction F2 of the pixel group UP, the spacer 14 partially overlaps with the first pixel opening a1, the second pixel opening a2, the third pixel opening a3 and the fourth pixel opening a4, respectively.

[0060] It is understandable that in the second direction F2, one end of the spacer 14 partially overlaps with the first pixel opening a1 and the third pixel opening a3, respectively, and the other end of the spacer 14 partially overlaps with the second pixel opening a2 and the fourth pixel opening a4, respectively, so as to save the area occupied by the spacer 14 in the first direction F1 and improve the aperture ratio of the display panel 100.

[0061] Optionally, in some embodiments of this application, in pixel group UP, the minimum distance L1 from the edge of spacer 14 to the edge of any pixel opening 13a is greater than 4 micrometers, so as to avoid affecting the light emission effect of sub-pixel P1.

[0062] Optionally, in some embodiments of this application, in pixel group UP, the minimum distance L1 from the edge of spacer 14 to the edge of any pixel opening 13a is less than or equal to 1 / 2 of the distance L2 between the edges of two adjacent pixel openings 13a.

[0063] Understandably, the minimum distance L1 is less than or equal to the distance L2 to avoid the spacer 14 being too small, so as to improve the support effect on the mask template 200.

[0064] Optionally, if the distance L2 between the edges of two adjacent pixel openings 13a is 18 micrometers, then the minimum distance L1 can be 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers or 9 micrometers.

[0065] Optionally, in some embodiments of this application, in pixel group UP, the minimum distance L1 from the edge of spacer 14 to the edge of any pixel opening 13a is equal to match the uniformity of supporting four mask templates 200.

[0066] Optionally, in some embodiments of this application, in pixel group UP, the extension p12 of sub-pixel P1 covers the edge portion of spacer 14.

[0067] Understandably, the size of the spacer 14 can be set relatively large to improve the performance of the spacer 14 in supporting the mask 200. Based on this, the spacer 14 will intrude into the opening of the mask 200, so that the extension p12 of the sub-pixel P1 covers the edge portion of the spacer 14.

[0068] Optionally, the spacer 14 has a size greater than 8 micrometers. For example, the spacer 14 has a size of 22 micrometers × 22 micrometers.

[0069] Optionally, in some embodiments of this application, in the first direction F1, two pixel units U1 are spaced apart between two adjacent spacers 14. In the second direction F2, two pixel units U1 are spaced apart between two adjacent spacers 14.

[0070] Multiple spacers 14 are arranged in rows along a first direction F1, and multiple spacers 14 are arranged in columns along a second direction F2. In the first direction F1, spacers 14 in odd-numbered columns are alternately arranged with spacers 14 in even-numbered columns. In the second direction F2, spacers 14 in odd-numbered rows are alternately arranged with spacers 14 in even-numbered rows.

[0071] It is understandable that the spacers 14 are staggered in the first direction F1 and the second direction F2 to improve the uniformity of the arrangement, thereby improving the uniformity of the support mask template 200.

[0072] For example, based on the above arrangement, and with the spacer 14 having a size of 22 micrometers × 22 micrometers, the density of the spacer 14 is approximately 2.4%.

[0073] It should be noted that the density is a percentage of the total area of ​​the spacers 14 in the smallest repeating unit to the total area of ​​the smallest repeating unit. The smallest repeating unit consists of 3×2 pixel units U1 and the corresponding 5 spacers 14.

[0074] Optionally, in some embodiments of this application, in the first direction F1, a pixel unit U1 is spaced between two adjacent spacers 14. In the second direction F2, a pixel unit U1 is spaced between two adjacent spacers 14.

[0075] Multiple spacers 14 are arranged in a row along the first direction F1, and multiple spacers 14 are arranged in a column along the second direction F2.

[0076] It is understandable that a pixel unit U1 is spaced between two adjacent spacers 14 to increase the number of spacers 14 and thus improve the support performance of the spacers 14.

[0077] Please refer to Figures 6 to 8 , Figure 6 This is another top view of the display panel 100 provided in this application embodiment. Figure 7 yes Figure 6 A cross-sectional view of the structure along line C2C2. Figure 8 This is a partial structural schematic diagram of another method for manufacturing a display panel 100 provided in this application embodiment.

[0078] It should be noted that, in Figures 6 to 8 In this section, the parts that differ from the above embodiments will be described in order to avoid redundant descriptions.

[0079] Optionally, in some embodiments of this application, in pixel group UP, the edge of the extension p12 of sub-pixel P1 ends on the edge of spacer 14 or ends outside the edge of spacer 14.

[0080] For example, in Figures 6 to 8 In the middle, the edge of the extension p12 of sub-pixel P1 ends at the edge of the spacer 14.

[0081] Understandably, because the spacer 14 is small in size and does not intrude into the outer extension p12 of the sub-pixel P1, the corner area of ​​the pixel opening 13a does not need to be cut with a large area, thereby increasing the light-emitting area of ​​the sub-pixel P1 and improving the aperture ratio; secondly, because the spacer 14 is small in size, more spacers 14 can be set to support the mask 200.

[0082] For example, in the first direction F1, there is a pixel unit U1 between two adjacent spacers 14, and in the second direction F2, there is a pixel unit U1 between two adjacent spacers 14. The plurality of spacers 14 are arranged in a row along the first direction F1, and the plurality of spacers 14 are arranged in a column along the second direction F2.

[0083] Based on the above arrangement, and considering that the spacer 14 has a size of 16 micrometers × 16 micrometers, the density of the spacer 14 is approximately 2.6%.

[0084] It should be noted that the density is a percentage of the total area of ​​the spacers 14 in the smallest repeating unit to the total area of ​​the smallest repeating unit. The smallest repeating unit consists of 3×2 pixel units U1 and the corresponding 5 spacers 14.

[0085] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of the display device 1000 provided in the embodiments of this application.

[0086] According to a second aspect of this application, a display device 1000 is provided, which includes a display panel 100 as described in any of the above embodiments.

[0087] It should be noted that the structure of the display panel 100 of the display device 1000 provided in this application embodiment is the same as the structure of the display panel 100 provided in any of the above embodiments of this application. For details, please refer to... Figures 1 to 8 Therefore, the relevant explanations will not be repeated here.

[0089] In the display device 1000 of this application embodiment, the light-emitting layer 15 includes a plurality of pixel units U1, each pixel unit U1 including four sub-pixels P1 of different colors, and a portion of the sub-pixels P1 covers the pixel opening 13a. The plurality of pixel units U1 are arranged in a first direction F1, and in a second direction F2 intersecting the first direction F1. In the display panel 100 at a top view, in two adjacent pixel units U1, in the second direction F2, two sub-pixels P1 of one pixel unit U1 and their corresponding pixel opening 13a, and two sub-pixels P1 of another pixel unit U1 and their corresponding pixel opening 13a are arranged adjacently to form a pixel group UP. The four sub-pixels P1 of the pixel group UP are of different colors. A spacer 14 is disposed in the area of ​​the pixel group UP, and the four sub-pixels P1 of the pixel group UP are arranged around the spacer 14. In the pixel group UP, the four pixel openings 13a form a non-right-angle transition surface towards the sidewall 14a of the spacer 14.

[0090] It is understood that in this embodiment of the application, the four pixel openings 13a in the pixel group UP are beveled to form a non-right angle transition surface, so as to make room for the spacer 14, without increasing the spacing of the pixel openings 13a in the first direction F1 and the second direction F2. At the same time, based on the four-color sub-pixels P1 surrounding the spacer 14, the spacer 14 can also be used to support the mask 200 for evaporating the four-color sub-pixels P1, so as to reduce the number of spacers 14. The two work together to improve the aperture ratio of the display panel 100.
