DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] As shown in the background technology section, how to optimize the display quality of OLED display panels has become a research hotspot for those skilled in the art.

[0045] In view of this, an embodiment of the present application provides a display panel, such as Figure 1 As shown, the display panel 100 includes:

[0046] An array substrate 20;

[0047] A pixel definition layer 10 located on one side of the array substrate 20, wherein the pixel definition layer 10 includes a plurality of pixel openings;

[0048] A light-emitting functional layer 30 located in the pixel opening, the light-emitting functional layer is an OLED (Organic Light-Emitting Diode);

[0049] Among them, Figure 2 As shown, Figure 1 for Figure 2 In the cross-sectional view along the EE' direction, the display panel includes a display area 001 and a frame area 002 surrounding the display area 001. A plurality of pixel openings are located in the display area 001. The plurality of pixel openings include:

[0050] The first column of pixel openings and the second column of pixel openings are arranged along the first direction X, the first column of pixel openings includes the first pixel openings 101 and the second pixel openings 102 periodically arranged along the second direction Y, and the second column of pixel openings includes the i-th third pixel opening 103, the i+1-th third pixel opening 103 and the i+2-th third pixel opening 103 arranged along the second direction Y, where i is an integer not less than 1. The first pixel opening 101 is provided with a first light-emitting functional layer, the second pixel opening 102 is provided with a second light-emitting functional layer, and the third pixel opening 103 is provided with a third light-emitting functional layer; in order to facilitate the illustration that different pixel openings correspond to different light-emitting functional layers, Figure 2Different colors are used to fill the first pixel opening 101, the second pixel opening 102 and the third pixel opening 103, but in actual production, multiple pixel openings can be formed at the same time.

[0051] Optionally, in one embodiment of the present application, continue as Figure 1 As shown, the display panel 100 further includes: an anode layer 31 located on the side of the light-emitting functional layer 30 facing the array substrate 20 and a cathode layer 32 located on the side of the light-emitting functional layer 30 away from the array substrate 20; a pixel circuit 201 is provided in the array substrate 20, and one pixel circuit 201 corresponds to one light-emitting functional layer 30, and is used to control the voltage on the anode layer 31 corresponding to the light-emitting functional layer 30, thereby controlling the light-emitting state of the light-emitting functional layer 30 by controlling the voltage difference between the anode layer 31 and the cathode layer 32 corresponding to the light-emitting functional layer 30, so as to control the display of the display panel. Among them, one light-emitting functional layer 30 and its corresponding pixel circuit 201, the anode layer 31 and the cathode layer 32 form one pixel 33, and one pixel 33 corresponds to one pixel opening.

[0052] Optionally, different light-emitting functional layers in the display panel may share the same cathode layer to simplify the manufacturing process of the cathode layer, but the present application does not limit this and it depends on the specific circumstances.

[0053] It should be noted that, in this embodiment, Figure 2 As shown, in the second direction Y, the spacing between the i-th third pixel opening 103 and the i+1-th third pixel opening 103 is d1, and the spacing between the i+1-th third pixel opening 103 and the i+2-th third pixel opening 103 is d2, d1≠d2, i is any positive integer not greater than N-2, and N is an integer greater than 4, so that during the formation of the third light-emitting functional layer, the i-th third light-emitting functional layer and the i+1-th third light-emitting functional layer can share an opening of the mask, thereby improving the aperture ratio of the i-th third light-emitting functional layer and the i+1-th third light-emitting functional layer, or, the i+ The first third light-emitting functional layer and the i+2th third light-emitting functional layer can share an opening of the mask plate, thereby increasing the aperture ratio of the i+1th third light-emitting functional layer and the i+2th third light-emitting functional layer, thereby increasing the display brightness of the third light-emitting functional layer in the display panel and improving the display quality of the display panel. That is, two third light-emitting functional layers that are adjacent in the second direction Y and have a small interval share an opening of the mask plate to increase the aperture ratio of the third light-emitting functional layer in the display panel, thereby increasing the display brightness of the third light-emitting functional layer in the display panel under the same driving signal, and ultimately improving the display quality of the display panel.

[0054] It should be noted that if the distance between two adjacent third pixel openings 103 in the second direction Y is too small, when a light modulation layer is added to the side of the pixel definition layer 10 in the display panel away from the array substrate 20, the light modulation layer can only be set above the gap between other adjacent pixel openings, and cannot be set above the gap between the two adjacent third pixel openings 103 with a smaller distance, resulting in display defects such as color deviation or dispersion, affecting the display quality.

[0055] In the present embodiment, in the second direction Y, the spacing between the adjacent first pixel openings 101 and the second pixel openings 102 is d3, d1≥d3 and d2≥d3, so that the distance between two adjacent third pixel openings 103 with a smaller distance is increased, so that a light modulation layer can be set above the gap between any two adjacent third pixel openings 103 in the second direction Y, thereby alleviating the phenomenon that the display quality deteriorates due to the small size of the gap above some adjacent third pixel openings 103 and the inability to set the light modulation layer, thereby improving the display quality of the display panel.

[0056] Since the luminous efficiency of the blue pixel is lower than the luminous efficiency of the red pixel and the luminous efficiency of the green pixel, in an optional embodiment of the present application, Figure 3 As shown, a red light-emitting functional layer R is arranged in the first pixel opening 101, a green light-emitting functional layer G is arranged in the second pixel opening 102, and a blue light-emitting functional layer B is arranged in the third pixel opening 103, so as to balance the luminous brightness of the red light-emitting functional layer R, the green light-emitting functional layer G and the blue light-emitting functional layer B under the same driving signal, but the present application does not limit this and it depends on the specific situation.

[0057] The display panel provided in the embodiment of the present application is described below by taking the example that a red light-emitting functional layer R is disposed in the first pixel opening 101 , a green light-emitting functional layer G is disposed in the second pixel opening 102 , and a blue light-emitting functional layer B is disposed in the third pixel opening 103 .

[0058] It should be noted that, in this embodiment, d1 may be smaller than d2 or larger than d2, and this application does not limit this, and it depends on the specific situation. For the convenience of description, the display panel provided in the embodiment of this application is described below by taking d1 < d2 as an example.

[0059] like Figure 4As shown, in the present embodiment, in the second direction Y, the spacing between the 2k+1th third pixel opening 103 and the 2k+2th third pixel opening 103 is d1, and k is any integer not less than 0; in the second direction Y, the spacing between the 2j+2th third pixel opening 103 and the 2j+3th third pixel opening 103 is d2, and j is any integer not less than 0, so that the arrangement of the third pixel openings 103 provided in the embodiment of the present application is extended to the entire display area of ​​the display panel, thereby further improving the display quality of the display panel.

[0060] In other embodiments of the present application, Figure 5 As shown, in the second direction Y, the spacing between the 2k+1 third pixel opening 103 and the 2k+2 third pixel opening 103 is d2, k is any integer not less than 0; in the second direction Y, the spacing between the 2j+2 third pixel opening 103 and the 2j+3 third pixel opening 103 is d1, j is any integer not less than 0, so that the arrangement of the third pixel openings 103 provided in the embodiment of the present application is extended to the entire display area of ​​the display panel, thereby further improving the display quality of the display panel. This application does not limit this, and it depends on the specific situation.

[0061] In the embodiment of the present application, the display panel includes a plurality of repeating units arranged in a display. The repeating unit 104 involves four columns of pixel openings in the first direction X, specifically two columns of first column pixel openings and two columns of second column pixel openings, and involves four adjacent rows of pixel openings in the second direction Y. Figure 4 As shown, the repeating unit 104 includes four first pixel openings 101, four second pixel openings 102 and four third pixel openings 103, wherein two first pixel openings 101 and two second pixel openings 102 are located in the first column and are arranged crosswise in the second direction Y, another two first pixel openings 101 and two second pixel openings 102 are located in the third column and are arranged crosswise in the second direction Y, two third pixel openings 103 are located in the second column, and the distance between the two third pixel openings 103 is d1, and another two third pixel openings 103 are located in the fourth column, and the distance between the two third pixel openings 103 is d2.

[0062] Optionally, in one embodiment of the present application, Figure 6 As shown, the i-th third pixel opening 103 and the r-th first pixel opening 101 are located in the same row, the i+1-th third pixel opening 103 and the t-th second pixel opening 102 are located in the same row, and the r-th first pixel opening 101 and the t-th second pixel opening 102 are located in adjacent rows, wherein r is an integer not less than 1, and t is an integer not less than 1.

[0063] Based on the above embodiment, in one embodiment of the present application, continue as follows Figure 6 As shown, d1=d3, that is, the spacing between the i-th third pixel opening 103 and the i+1-th third pixel opening 103 is the same as the spacing between the r-th first pixel opening 101 and the t-th second pixel opening 102, so that the distance between two adjacent third pixel openings 103 with a smaller distance is increased to the same as the distance between the first pixel opening 101 and the second pixel opening 102 adjacent to each other in the second direction Y, so that a light modulation layer can be set above the gap between any two adjacent third pixel openings 103 in the second direction Y, thereby alleviating the phenomenon of deterioration of display quality caused by the inability to set a light modulation layer above the gap between some adjacent third pixel openings 103 due to the small size, thereby improving the display quality of the display panel.

[0064] It should be noted that, in the above embodiment, Figure 6 As shown, in the second direction Y, the i-th third pixel opening 103 has a first position A toward the boundary of the i+1-th third pixel opening 103, and the r-th first pixel opening 101 has a second position B toward the boundary of the t-th second pixel opening 102; in the second direction Y, the i+1-th third pixel opening 103 has a third position C toward the boundary of the i-th third pixel opening 103, and the t-th second pixel opening 102 has a fourth position D toward the boundary of the r-th first pixel opening 101.

[0065] Optionally, in one embodiment of the present application, in the second direction Y, the first position A and the second position B are the same, and the third position C and the fourth position D are the same, so that the boundary of the i-th third pixel opening 103 toward the i+1-th third pixel opening 103 is flush with the boundary of the r-th first pixel opening 101 toward the t-th second pixel opening 102 in the second direction Y, and the boundary of the i+1-th third pixel opening 103 toward the i-th third pixel opening 103 and the boundary of the t-th second pixel opening 102 toward the r-th first pixel opening 101 are flush in the second direction Y, that is, the lower edge of the i-th third pixel opening 103 is flush with the lower edge of the r-th first pixel opening 101, and the upper edge of the i+1-th third pixel opening 103 is flush with the upper edge of the t-th second pixel opening 102.

[0066] In another embodiment of the present application, Figure 7 and Figure 8As shown, in the second direction Y, the first position A and the second position B are different, and the third position C and the fourth position D are different, so that the boundary of the i-th third pixel opening 103 toward the i+1-th third pixel opening 103 and the boundary of the r-th first pixel opening 101 toward the t-th second pixel opening 102 are not flush in the second direction Y, and the boundary of the i+1-th third pixel opening 103 toward the i-th third pixel opening 103 and the boundary of the t-th second pixel opening 102 toward the r-th first pixel opening 101 are not flush in the second direction Y, that is, the lower edge of the i-th third pixel opening 103 is not flush with the lower edge of the r-th first pixel opening 101, and the upper edge of the i+1-th third pixel opening 103 is not flush with the upper edge of the t-th second pixel opening 102.

[0067] Optionally, based on the above embodiment, in one embodiment of the present application, Figure 7 As shown, in the second direction Y, the first position A is located on the side of the second position B toward the fourth position D, and the third position C is located on the side of the fourth position D away from the second position B; in another embodiment of the present application, as Figure 8 As shown, in the second direction Y, the first position A is located on a side of the second position B away from the fourth position D, and the third position C is located on a side of the fourth position D toward the second position B.

[0068] Continue as Figure 8 As shown, in an embodiment of the present application, the display panel includes a plurality of pixel unit areas, and a pixel unit area includes a first pixel opening 101, a second pixel opening 102 and a third pixel opening 103. Optionally, in an embodiment of the present application, the t-1th second pixel opening 102, the rth first pixel opening 101 and the i-th third pixel opening 103 constitute a first pixel unit area 11, and the tth second pixel opening 102, the r+1th first pixel opening 101 and the i+1th third pixel opening 103 constitute a second pixel unit area 12. It should be noted that, in the present embodiment, the first position A is located on the side of the fourth position D toward the second position B, that is, in the second direction Y, the lower edge of the i-th third pixel opening 103 will not exceed the upper edge of the t-th second pixel opening 102, and the third position C is located on the side of the second position B toward the fourth position D, that is, in the second direction Y, the upper edge of the i+1-th third pixel opening 103 will not exceed the lower edge of the r-th first pixel opening 101, so that the display effects of the display areas corresponding to the first pixel unit area 11 and the second pixel unit area 12 can be independent of each other, reducing the mutual influence between the display contents corresponding to the first pixel unit area 11 and the second pixel unit area 12.

[0069] It should be noted that, under the premise of d1=d3, compared with the first position A and the second position B being different, and the third position C and the fourth position D being different in the second direction Y, the first position A and the second position B being the same, and the third position C and the fourth position D being the same in the second direction Y, the display quality of the display panel is better improved. That is, compared with the pixel in the display panel adopting Figure 7 and Figure 8 The display panel adopts Figure 6 The arrangement method is more effective in improving the display quality of the display panel.

[0070] In another embodiment of the present application, d1>d3, that is, the spacing between the i-th third pixel opening 103 and the i+1-th third pixel opening 103 is greater than the spacing between the r-th first pixel opening 101 and the t-th second pixel opening 102, so as to increase the distance between two adjacent third pixel openings 103 with a smaller distance to be greater than the distance between the first pixel opening 101 and the second pixel opening 102 adjacent to each other in the second direction Y, so that a light modulation layer can be set above the gap between any two adjacent third pixel openings 103 in the second direction Y, thereby alleviating the phenomenon that the display quality deteriorates due to the small size of the gap above some adjacent third pixel openings 103 and the inability to set the light modulation layer, thereby improving the display quality of the display panel.

[0071] In addition, d1>d3, that is, the spacing between the i-th third pixel opening 103 and the i+1-th third pixel opening 103 is greater than the spacing between the r-th first pixel opening 101 and the t-th second pixel opening 102. Under the premise that the size of the evaporation opening of the mask for making the third pixel opening 103 remains unchanged, the aspect ratio of the third pixel opening 103 can be reduced, that is, Fig. 9 The aspect ratio of the third pixel opening 103 shown in FIG. Figure 6-Figure 8 The aspect ratio of the third pixel opening 103 is improved, thereby alleviating display defects such as color shift or dispersion caused by the different length and width dimensions of the third light-emitting functional layer, and improving the display quality of the display panel.

[0072] Optionally, in the above embodiment, if Figure 10-12 As shown, in the second direction Y, the first position A is located on the side of the fourth position D toward the second position B, and the third position C is located on the side of the second position B toward the fourth position D, so that the display effects of the display areas corresponding to the first pixel unit area 11 and the second pixel unit area 12 can be independent of each other, reducing the mutual influence between the display contents corresponding to the first pixel unit area 11 and the second pixel unit area 12. However, the present application does not limit this, as long as the first position A is not located on the side of the fourth position D away from the second position B, and the third position C is not located on the side of the second position B away from the fourth position D.

[0073] Optionally, in one embodiment of the present application, Fig.10 As shown, the first position A is the same as the second position B, and the third position is located on the side of the fourth position D away from the second position B, so as to reduce the length of the i+1th third pixel opening 103 in the second direction Y, increase the distance between the i-th third pixel opening 103 and the i+1th third pixel opening 103, improve the display quality of the display panel, such as color deviation or dispersion, after the light modulation layer is superimposed, and improve the display quality of the display panel.

[0074] It should be noted that in the above embodiments, Fig.11 As shown, the size of the i-th third pixel opening 103 in the second direction Y may be the same as the size of the i+1-th third pixel opening 103 in the second direction Y, so that the areas of the opening regions of the third pixel openings 103 are the same, but the present application is not limited to this.

In other embodiments of the present application, the size of the i-th third pixel opening 103 in the second direction Y may also be different from the size of the i+1-th third pixel opening 103 in the second direction Y, such as Fig.12 As shown, subject to availability.

[0077] In another embodiment of the present application, Fig.14As shown, the first position A and the second position B are different, and the third position C and the fourth position D are different, so as to reduce the length of the i-th third pixel opening 103 in the second direction Y and the length of the i+1-th third pixel opening 103 in the second direction Y, increase the distance between the i-th third pixel opening 103 and the i+1-th third pixel opening 103, improve the display quality of the display panel, such as color deviation or dispersion after the light modulation layer is superimposed in the display panel, and improve the display quality of the display panel.

However, the present application does not limit this, as long as the first position A is not located on the side of the fourth position D away from the second position B, and the third position C is not located on the side of the second position B away from the fourth position D.

That is, in the present embodiment, as Fig.18 and Fig.19 As shown, Fig.19 for Fig.17 In the cross-sectional view along MM', due to the large number of reference numerals, in order to facilitate the illustration of the reference numerals and their corresponding positions, at the pixel opening position, Fig.19 The anode layer and the cathode layer are no longer shown in the subsequent cross-sectional views, and the first light modulating portion 61 is correspondingly arranged above the gap between any two adjacent first pixel openings 101 and the second pixel opening 102, and the first light modulating portion 61 is also correspondingly arranged above the gap between any two adjacent third pixel openings 103, so that the first light modulating portion 61 is correspondingly arranged above the gap between any two adjacent pixel openings, thereby improving the display quality of the display panel due to the small gap between the i-th third pixel opening 1031 and the i+1-th third pixel opening 1032, thereby improving the display quality of the display panel due to the color deviation or dispersion caused by the inability to set the first light modulating portion 61 above the i-th third pixel opening 1031 and the i+1-th third pixel opening 1032.

[0083] Specifically, in one embodiment of the present application, continue as follows Fig.18 and Fig.19 As shown, the plurality of first light modulation parts 61 include a first sub-light modulation part 611, a second sub-light modulation part 612 and a third sub-light modulation part 613, wherein:

[0086] In the second direction Y, there is a third gap d3 between the adjacent first pixel opening 101 and the second pixel opening 102 ; in the third direction Z, the third sub-light modulation portion 613 overlaps the third gap d3 .

[0087] Optionally, in one embodiment of the present application, continue as Fig.18 As shown, d1<d2, in the second direction Y, the width of the second sub-light modulation portion 612 is greater than the width of the first sub-light modulation portion 611. In the present embodiment, optionally, d1 is greater than 6μm to ensure the improvement effect on the display quality of the display panel without increasing the process difficulty of the first light modulation portion 61; this is not limited in the present application. In other embodiments of the present application, d1>d2 may also be true. Accordingly, in the second direction Y, the width of the second sub-light modulation portion 612 is less than the width of the first sub-light modulation portion 611, depending on the specific circumstances.

[0088] It should be noted that, in the above embodiment, if d3<d1, then in the second direction Y, the width of the first sub-light modulation portion 611 is greater than the width of the third sub-light modulation portion 613; if d3 is equal to d1, then in the second direction Y, the width of the first sub-light modulation portion 611 is equal to the width of the third sub-light modulation portion 613.

[0089] Based on any of the above embodiments, in one embodiment of the present application, continue as follows Figure 18-Figure 19 As shown, the light modulation structure 60 also includes: a second light modulation part 62 located on the side of the first light modulation part 61 away from the array substrate 20, covering the display area of ​​the display panel, the second light modulation part 62 has a different refractive index from the first light modulation part 61, so as to utilize the interface between the first light modulation part 61 and the second light modulation part 62 to form a functional interface, and the functional interface can deflect the large-angle light emitted by the light-emitting functional layer 30. After the action of the functional interface, the light is deflected toward the normal viewing direction of the display panel, reducing the probability of total reflection of the light inside the display panel, thereby improving the light extraction efficiency of the light-emitting functional layer 30, and further improving the light-emitting efficiency of the display panel.

[0090] Optionally, in one embodiment of the present application, continue as Fig.18 As shown, the refractive index of the first light modulation part 61 is less than the refractive index of the second light modulation part 62. In this embodiment, when the large-angle light emitted by the light-emitting functional layer 30 is emitted from the first light modulation part 61 to the second light modulation part 62, the light is emitted from the optically sparse medium to the optically dense medium, and the incident angle is greater than the refraction angle. Compared with the incident light, the angle between the refracted light emitted from the second light modulation part 62 and the third direction Z becomes smaller, such as the light S1, that is, the light emitted from the second light modulation part 62 is deflected toward the normal viewing direction of the display panel, thereby reducing the probability of total reflection of the light inside the display panel, and improving the light extraction efficiency of the light-emitting functional layer 30 and the luminous efficiency of the display panel. When the large-angle light emitted by the light-emitting functional layer 30 is emitted from the second light modulation part 62 to the first light modulation part 61, the light is emitted from the optically dense medium to the optically sparse medium, and total reflection can occur when the incident angle is greater than the critical angle. Compared with the incident light, the angle between the total reflected light and the third direction Z is also smaller, such as the light S2, which can also improve the light extraction efficiency of the light emitting functional layer 30, thereby improving the light emitting efficiency of the display panel.

Compared with the incident light, the angle between the refracted light and the third direction Z is also reduced, so that the large-angle light is deflected toward the normal viewing direction of the display panel, such as light S3, reducing the probability of total reflection of the light inside the display panel, which can improve the light extraction efficiency of the light-emitting function 30, thereby improving the light-emitting efficiency of the display panel.

[0094] Optionally, in the above embodiment, in the third direction Z, the second light modulation part 62 covers its corresponding light emitting functional layer 30, so that the first light modulation part 61 and the second light modulation part 62 can modulate more large-angle light, thereby improving the light output efficiency of the light emitting functional layer 30, thereby improving the luminous efficiency of the display panel.

Optionally, in this embodiment, continue as Fig.18 As shown, the distance d1 between the i-th third pixel opening 1031 and the i+1-th third pixel opening 1032 is greater than 4 μm to ensure the improvement of the display quality of the display panel without increasing the process difficulty of the first light modulation part 61.
