[0001] The present disclosure generally relates to the field of display panel technology, and more particularly to a display panel, a method for manufacturing a display panel, a device and a medium. Background Art

[0002] With the continuous development of display panels, the types of display panels are becoming more and more diverse. Organic Light-Emitting Diode (OLED) display panel is one type of display panel.

[0003] In an OLED display panel, the principle of light emission is through the injection and recombination of carriers, and the brightness of the light emission is proportional to the injected current. In the related art, the display process of the display panel is completed by three light-emitting elements of different colors. The sensitivity of light-emitting elements of different colors to the current is different. Among them, the green light-emitting element is the most sensitive to the current. Therefore, it is easy to have a situation where the brightness of the green light-emitting element is too different from that of the other two colors of light-emitting elements. Summary of the invention

In this way, by setting the first touch electrode film layer in the isolation structure corresponding to all the green light-emitting elements of the entire panel, the isolation structure around the green light-emitting element is increased compared with the previous one during the light-emitting process, thereby reducing the light-emitting angle and the light-emitting range, thereby reducing the brightness corresponding to the green light-emitting element in the display panel, reducing the brightness difference between the green light-emitting element and other light-emitting elements, and balancing the light-emitting brightness of the entire display panel.

DETAILED DESCRIPTION

[0013] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0014] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The following will describe the implementation scenarios of the present application in conjunction with the reference drawings.

[0015] In OLED display panels, the principle of light emission is that light is generated by the injection and recombination of carriers, and the brightness of the light is proportional to the injected current. Figure 1 As shown, Figure 1 It can be seen that the solid line 11, the solid line 12 and the solid line 13 are used to represent the brightness change trend of the green pixel, the red pixel and the blue pixel as the current increases, respectively. Figure 1The unit of the horizontal axis is A, and the vertical axis has no unit, which is only a representation of the relative brightness change. Figure 1 It can be seen that the change trend of the solid line 11 used to characterize the change in the brightness of the green pixel is obviously much greater than the change trend of the other two pixels. In practical applications, the carrier injection and recombination process of the display panel is dynamically changing and cannot be completely stabilized at a certain current value. In this way, the brightness of the green pixel area will often be much greater than the brightness of the other two pixel areas, which will give people the feeling that the brightness of the display panel is uneven and has a color cast.

[0016] like Figure 2 As shown, Figure 2 A top view of a display panel in the related art is shown, in which the AA area and the BB area are marked, wherein the AA area is the cross-sectional position having the first touch electrode film layer (TMA film layer), and the BB area is the cross-sectional position corresponding to the green pixel area in the related art. Figure 2 It includes a red pixel color film layer 14, which is arranged in a pixel opening area 15 of the red pixel color film layer; a green pixel color film layer 16, which is arranged in a pixel opening area 17 of the green pixel color film layer; and a blue pixel color film layer 18, which is arranged in a pixel opening area 19 of the blue pixel color film layer.

[0017] like Figure 3 and Figure 4 As shown, Figure 3 A side cross-sectional view including the AA region and Figure 4 Including the side cross-sectional view of the BB area. It can be seen that the AA area has a TMA film layer 21. In the related art, the second touch electrode film layers (TMB film layers) 22 located on both sides of the TMA film layer 21 may be touch electrode film layers with different signal transmission functions (for example, the TMB film layer on one side is a touch electrode film layer for receiving touch signals, and the TMB film layer on one side is a touch electrode film layer for sending touch signals). Then, by setting the TMA film layer 21 in the middle of the second touch electrode film layers 22 on both sides, and perforating the insulating film layer TBL film layer 23 on the side of the TMA film layer 21 away from the substrate, the TMA film layer 21 acts as a bridge electrode to transmit signals between the second touch electrode film layers 22 with different functions on both sides. Correspondingly, in the BB area, the BB area is Figure 2 A side view of any green pixel color filter layer 16 and a corresponding pixel opening area 17 of the green pixel color filter layer 16. Figure 4 It can be seen that in Figure 4 In the example, only the second touch electrode film layer 22 is disposed in the region of the pixel opening region 17 of the green pixel film layer 16, and the light range 20 emitted by the green pixel film layer 16 from the pixel opening region 17 is as follows: Figure 4 As indicated by the markings.

[0018] Based on this, the present application proposes a display panel, a method for manufacturing a display panel, an apparatus and a medium, which can solve the problem that in the existing display panel, the green light-emitting element is the most sensitive to current, and therefore, it is easy for the brightness of the green light-emitting element to differ too much from the brightness of the other two colors of light-emitting elements. The brightness corresponding to the green light-emitting element in the display panel is reduced, the brightness difference between the green light-emitting element and the other light-emitting elements is narrowed, and the light brightness of the entire display panel is balanced.

[0019] Figure 5 It is a structural schematic diagram of a display panel provided in an embodiment of the present application, wherein the display panel comprises: a substrate, a light-emitting structure layer arranged on one side of the substrate, the light-emitting structure layer comprising a pixel definition layer and a plurality of light-emitting elements, and isolation structures are arranged between different light-emitting elements.

[0020] In the embodiment of the present application, a plurality of light-emitting elements are arranged in the light-emitting structure layer in the display panel, and adjacent light-emitting elements are of different colors.

[0021] It is understandable that a display panel usually forms a light-emitting array through red, blue and green color pixels. In the display panel, in order to ensure rich and uniform colors, adjacent light-emitting elements are provided with different pigment film layers to emit light of different colors.

[0022] like Figures 5 to 7 As shown, Figure 5 The figure shows a partial top view of the display panel of the present application, in which the AA area and the BB area are marked, wherein the AA area is the cross-sectional position of the display panel having the first touch electrode film layer (TMA film layer), and the BB area is the cross-sectional position corresponding to the green pixel area. Figure 5 The top view shown includes three types of pixels, which are respectively a pixel opening area 51 of the red pixel film layer, a pixel opening area 52 of the green pixel film layer, and a pixel opening area 53 of the blue pixel film layer. It can be seen from the top view that the pigment film layers of the light-emitting elements corresponding to these three pixels are respectively a red light-emitting film layer 54, a green light-emitting film layer 31 and a blue light-emitting film layer 55.

[0023] Figure 6 The side view and Figure 7 Shown is a side view of the display panel after a cross section is taken at the above-mentioned AA area. Figure 6 The AA area side view in FIG. 1 includes: a first touch electrode film layer 61 and second touch electrode film layers 62 with different functions located on both sides, wherein the second touch electrode film layers 62 with different functions on both sides are electrically connected through the first touch electrode film layer 61 .

[0024] exist Figure 7 It can be seen that Figure 7FIG. 3 shows a side view of a single green light emitting element 31. It can be seen that a first isolation structure 32 for isolating the green light emitting element from other light emitting elements is provided on both sides of the single green light emitting element 31. Figure 6 and Figure 7 The side views shown in FIG. 1 and FIG. 2 all show the light emitting structure layer of the display panel. Figure 7 In the figure, a green light emitting element 31 is included. The green light emitting element 31 transmits light from the pixel opening area 52 in the figure to a side away from the substrate (not shown in the figure). Figure 7 In the figure, the transmission range of the green light emitting element 31 is the corresponding area of ​​the dotted line 71, which is consistent with the above-mentioned related technology, that is, Figure 4 Compared to the transmission range 20 shown in , the transmission range is significantly narrowed.

[0025] In an embodiment of the present application, the first isolation structure between the green light-emitting element and the other light-emitting elements includes a first touch electrode film layer and a second touch electrode film layer that are stacked, an insulating film layer is arranged between the first touch electrode film layer and the second touch electrode film layer, and the first touch electrode film layer and the second touch electrode film layer are electrically isolated.

[0026] Exemplarily, the first touch electrode film layer may be a TMA film layer, and the second touch electrode film layer may be a TMB film layer.

[0027] It can be understood that in the embodiment of the present application, it can be known from the above content that the green light-emitting element is more sensitive to current, and therefore the brightness of the light it displays is often much greater than the brightness of the light transmitted by the other two colors of light-emitting elements. Therefore, in the embodiment of the present application, by adding a first touch electrode film layer to the first isolation structure used to isolate the green light-emitting element from other light-emitting elements, the height of the first isolation structure around all green light-emitting elements that does not include the first touch electrode film layer in the related technology is increased, and the increased height is the first touch electrode film layer, so that the first isolation structure can block a portion of the light emitted by the green light-emitting element, so that the brightness difference between the brightness of the light transmitted by the green light-emitting element and the brightness of the light transmitted by the other light-emitting elements is greatly reduced.

[0028] It should be noted that, as can be seen from the aforementioned content, the first touch electrode film layer is used to transmit signals between the second touch electrode film layers with different functions. Therefore, in the display panel, there are some scattered green light-emitting elements and the isolation structure around them, and a bridge electrode for transmitting signals is provided, that is, the first touch electrode film layer. As can be seen from the aforementioned content, the first touch electrode film layer used to transmit signals between the second touch electrode film layers with different functions needs to be perforated at the insulating film layer so that the first touch electrode film layer and the second touch electrode film layer are electrically connected. In the embodiment of the present application, the first touch electrode film layer is provided in the first isolation structure in which the first touch electrode film layer is not provided in the related art. This part of the first isolation structure in which the first touch electrode film layer is not provided is the first touch electrode film layer electrically isolated from the second touch electrode film layer. Exemplarily, the insulating film layer may be a TBL film layer.

[0029] like Figure 7 As shown, in Figure 7 In the figure, a green light-emitting element 31 is included. The light-emitting element 31 is provided with a first isolation structure 32 on both sides. In the first isolation structure 32, a first touch electrode film layer 34 is provided. An insulating film layer 35 is provided on the side of the first touch-click film layer 34 away from the substrate. A second touch electrode film layer 36 is provided on the side of the insulating film layer 35 away from the substrate. The first touch-click film layer 34 and the second touch electrode film layer 36 are electrically isolated by the insulating film layer 35. The first light-emitting element 31 transmits light from the pixel opening area 33 in the figure to the side away from the substrate (not shown in the figure). At the same time, since the first isolation structure is higher than other isolation structures, the brightness of the light transmitted by the first light-emitting element 31 is smaller than the brightness of the light transmitted by other light-emitting elements.

[0030] In the present application, the display panel includes a substrate and a light-emitting structure layer arranged on one side of the substrate. The light-emitting structure layer includes a pixel definition layer and a plurality of light-emitting elements, and an isolation structure is arranged between different light-emitting elements. The first isolation structure between the green light-emitting element and the other light-emitting elements among the above-mentioned plurality of light-emitting elements includes a first touch electrode film layer and a second touch electrode film layer arranged in a stacked manner, an insulating film layer is arranged between the first touch electrode film layer and the second touch electrode film layer, and the first touch electrode film layer and the second touch electrode film layer are electrically isolated. In this way, by setting the first touch electrode film layer in the isolation structure corresponding to all the green light-emitting elements of the entire panel, the isolation structure around the green light-emitting element is increased compared with the previous one during the light-emitting process, thereby reducing the light-emitting angle and the light-emitting range, thereby reducing the brightness corresponding to the green light-emitting element in the display panel, reducing the brightness difference between the green light-emitting element and other light-emitting elements, and balancing the light-emitting brightness of the entire display panel.

[0031] Optionally, in the embodiment of the present application, a projection pattern of the first touch electrode film layer in the orthographic projection direction is a closed pattern or a non-closed pattern.

[0032] It can be understood that in the embodiment of the present application, the reason for adding the first touch electrode film layer to the isolation structure between all green light-emitting elements and other light-emitting elements is that by increasing the height of the first isolation structure, the light transmittance of the green light-emitting element from its pixel opening area is reduced. Based on this, its main purpose is to increase the height of the first isolation structure. Therefore, the projection pattern of the first touch electrode film layer in the orthographic projection direction can be closed or non-closed, that is, the first touch electrode film layer can be a discontinuous structure or a continuous structure. The first touch electrode film layer ensures that the first isolation structure can be raised, and when the first touch electrode film layer is a discontinuous structure, the pixel opening area will not leak light from the discontinuity of the discontinuous structure.

[0033] Optionally, in an embodiment of the present application, when the first touch electrode film layer in the first isolation structure constitutes a non-enclosed structure, a ratio between an area of ​​a projection pattern of the first touch electrode film layer and an area of ​​a projection pattern of the first isolation structure is greater than a first preset ratio.

[0034] It is understandable that when the first touch electrode film layer is a non-enclosed structure, it is necessary to ensure that the pixel opening area does not leak light from the discontinuity of the discontinuity structure. The reason is that if there are too many discontinuity structures in the non-enclosed structure, the light of the first light-emitting element may leak from the discontinuity structure. Therefore, it is necessary to control the proportion of the discontinuity area of ​​the first touch electrode film layer that is a non-enclosed structure.

[0035] Specifically, by controlling the ratio between the area of ​​the projection pattern of the first touch electrode film layer on the substrate and the area of ​​the projection pattern of the first isolation structure on the substrate to be greater than a first preset ratio, the requirement of no light leakage can be ensured.

[0036] Optionally, in the embodiment of the present application, on the basis of increasing the height of the first isolation structure, the size of the light-transmitting area of ​​the pixel opening area of ​​the green light-emitting element can be controlled by changing the size of the orthographic projection pattern of the first touch electrode film layer in the first isolation structure on the substrate. Exemplarily, the side of the green light-emitting element away from the substrate is the pixel opening area, and the boundary of the first touch electrode film layer close to the pixel opening area overlaps with the boundary of the second orthographic projection of the pixel opening area on the substrate, or the first orthographic projection is within the second orthographic projection.

[0037] It can be understood that in the embodiment of the present application, Figure 5It can be seen that the pixel opening area 51 of the red pixel, the pixel opening area 52 of the green pixel, and the pixel opening area 53 of the blue pixel have different occupied areas. Figure 5 , the ratio relationship between the areas occupied by the three types of pixels of one display panel is shown. In fact, the ratio relationship between the areas occupied by the three types of pixels of different types of display panels may be different. In some display panels, the ratio of the area occupied by the pixel opening area 52 of the green pixel may be too large. In the case where the ratio of the area occupied by the pixel opening area 52 of the green pixel may be too large, the first touch electrode film layer may be partially extended into the pixel opening area 52 of the green pixel, thereby further shielding a portion of the light transmitted from the pixel opening area 52 by the green light emitting element 31.

[0038] Exemplarily, the first touch electrode film layer is close to the pixel opening area on the first orthographic projection of the substrate. For example, Figure 5 As shown, in Figure 5 In the embodiment, the first orthographic projection of the boundary 57 of the first touch electrode film layer 61 close to the pixel opening area 52 on the substrate overlaps with the boundary 58 of the second orthographic projection of the pixel opening area 52 on the substrate. Figure 7 It can be seen that the boundary 57 and the boundary 58 overlap, but belong to the first touch electrode film layer 61 and the pixel opening area 52 of the green light emitting element 31 respectively.

[0039] For example, Figure 8 As shown, in Figure 8 The top view of the display panel shown includes three types of pixels, which are respectively a pixel opening area 81 of the red pixel film layer, a pixel opening area 82 of the green pixel film layer, and a pixel opening area 53 of the blue pixel film layer. It can be seen from the top view that the pigment film layers of the light-emitting elements corresponding to these three pixels are respectively a red light-emitting film layer 84, a green light-emitting film layer 85 and a blue light-emitting film layer 86.

[0040] exist Figure 8 In the embodiment, the boundary 88 of the first touch electrode film layer 87 close to the pixel opening area 82 is within the first orthographic projection of the substrate and the boundary 89 of the second orthographic projection of the pixel opening area 82 on the substrate, combined with Figure 7 It can be seen that the boundary 88 and the boundary 89 are non-overlapping and the boundary 88 is within the second orthographic projection corresponding to the boundary 89. The boundary 88 and the boundary 89 belong to the first touch electrode film layer 87 and the pixel opening area 82 of the green light emitting element 85. Figure 8 Side view of the middle BB area Fig. 9 , it can be seen that boundary 88 and boundary 89 do not overlap, and boundary 88 is within boundary 89.

[0041] Optionally, in an embodiment of the present application, when the first orthographic projection is within the second orthographic projection, a ratio of an overlapping area between the first orthographic projection and the second orthographic projection to the second orthographic projection is less than or equal to a preset ratio.

[0042] Exemplarily, the preset ratio enables the light of the light emitting element to be transmitted from the pixel opening area corresponding to the green light emitting element at a preset angle.

[0043] It can be understood that in the embodiment of the present application, when the first orthographic projection is within the second orthographic projection, the shielding area of ​​the pixel opening area that needs to be shielded by the first touch electrode film layer needs to be limited, so as to ensure that the green light-emitting unit can transmit light from its pixel opening area without affecting the normal display effect of the display panel, and to ensure that the brightness of the light transmitted by the green light-emitting unit is not too bright, which affects the uniformity of the display of the display panel. Therefore, it is necessary to limit the overlapping ratio of the overlapping area of ​​the first orthographic projection in the second orthographic projection, and first locate the preset ratio. The preset ratio allows the light of the light-emitting unit to be transmitted from the pixel opening area of ​​the green light-emitting element at a preset angle.

[0044] Optionally, in an embodiment of the present application, the above preset ratio is 4%.

[0045] It can be understood that, when the ratio of the overlapping area of ​​the first orthographic projection and the second orthographic projection to the second orthographic projection is less than or equal to 4%, there will be no problem with the uniformity of the display panel and the green light transmission.

[0046] It should be noted that the above 4% is the maximum ratio of the overlapping area between the first orthographic projection and the second orthographic projection. On the one hand, the preset ratio is an adjustable ratio, and the ratio of the overlapping area may be different for different types of display panels; on the other hand, for any type of display panel, the ratio of the overlapping area should not exceed the preset ratio, otherwise it will affect the green light transmission of the green light-emitting unit of the display panel.

[0047] In this way, the effect of the transmitted light is ensured, and the brightness of the transmitted light of the green light emitting unit of the display panel is not too large, thereby ensuring uniformity.

[0048] Optionally, in an embodiment of the present application, the first isolation structure includes: a touch buffer film layer on one side of the pixel definition layer, the first touch electrode film layer arranged on the side of the touch buffer film layer away from the pixel definition layer, the insulating film layer arranged on the side of the first touch electrode film layer away from the pixel definition layer, and the second touch electrode film layer arranged on the side of the insulating film layer away from the pixel definition layer.

[0049] Exemplarily, the insulating film layer and the touch buffer film layer are transparent film layers.

[0050] In an example, the touch buffer film layer may be a TBR film layer (Touch Barrier film layer).

[0051] For example, Figure 7 As shown, in Figure 7 It can be seen that the first isolation structure includes a pixel definition layer 60, a touch buffer film layer 63 located on one side of the pixel definition layer 60, the first touch electrode film layer 61 arranged on the side of the touch buffer film layer 63 away from the pixel definition layer 60, the insulating film layer (TBL) 64 arranged on the side of the first touch electrode film layer 61 away from the pixel definition layer 60, and the second touch electrode film layer 62 arranged on the side of the insulating film layer 64 away from the pixel definition layer 60.

[0052] For example, Fig. 9 As shown, in Fig. 9 It can be seen that the first isolation structure includes a pixel definition layer 91, a touch buffer film layer 92 located on one side of the pixel definition layer 91, the first touch electrode film layer 87 arranged on the side of the touch buffer film layer 92 away from the pixel definition layer 91, the insulating film layer (TBL) 93 arranged on the side of the first touch electrode film layer 87 away from the pixel definition layer 91, and the second touch electrode film layer 94 arranged on the side of the insulating film layer 93 away from the pixel definition layer 91.

[0053] Fig.10 FIG. 1 is a flow chart of a method for manufacturing a display panel provided by an embodiment of the present application. Fig.10 As shown, the display panel includes: a substrate, a light emitting structure layer arranged on one side of the substrate, the light emitting structure layer includes a pixel definition layer, a plurality of light emitting elements, and an isolation structure is arranged between different light emitting elements; the method includes the following steps 301: Step 301: etching the first touch electrode film layer through a first mask so that a first isolation structure between the green light emitting element and other light emitting elements includes a first touch electrode film layer and a second touch electrode film layer which are stacked.

[0054] In the embodiment of the present application, an insulating film layer is disposed between the first touch electrode film layer and the second touch electrode film layer, and the first touch electrode film layer and the second touch electrode film layer are electrically isolated.

[0055] Exemplarily, the first mask is a mask for etching the first touch electrode film layer.

[0056] Exemplarily, the first mask is preset in advance.

[0057] It can be understood that in the embodiment of the present application, after the first touch electrode film layer is coated to generate a whole layer, the first touch electrode film layer can be etched through the first mask set in advance. Among them, the first touch electrode film layer etched by the first mask can have two characteristics: 1) the area where the first touch electrode film layer that functions as a bridge electrode is located can be retained by etching by the first mask; 2) the first touch electrode film layer in the first isolation structure of all isolation structures in the display panel can be retained by etching by the first mask, and the etching area can be determined according to the size ratio of the pixel opening area corresponding to the green light-emitting element and the pixel opening area corresponding to other light-emitting elements.

[0058] It should be noted that, in the process of retaining the first touch electrode film layer in the first isolation structure, only the etching area in the first mask needs to be changed, and no other masks need to be changed or added. It can be understood that for the first touch electrode film layer in the first isolation structure that did not previously have a bridge electrode structure, it only has the function of increasing the height of the first isolation structure, and does not have other functions, and there is no need to change other masks. For example, the first touch electrode film layer in the first isolation structure does not have the function of electrically connecting with the second touch electrode film layer, so there is no need to change the mask used for etching the insulating film layer (the previous function of the mask was to etch and generate electrical connection holes connecting the first touch electrode film layer and the second touch electrode film layer).

[0059] In the method provided in the embodiment of the present application, the display panel includes a substrate and a light-emitting structure layer arranged on one side of the substrate. The light-emitting structure layer includes a pixel definition layer and a plurality of light-emitting elements, and an isolation structure is arranged between different light-emitting elements. The first touch electrode film layer is etched by a first mask, so that the first isolation structure between the green light-emitting element and the other light-emitting elements in the above-mentioned plurality of light-emitting elements includes a first touch electrode film layer and a second touch electrode film layer arranged in a stacked manner, an insulating film layer is arranged between the first touch electrode film layer and the second touch electrode film layer, and the first touch electrode film layer and the second touch electrode film layer are electrically isolated. In this way, by setting the first touch electrode film layer in the isolation structure corresponding to all the green light-emitting elements of the entire panel, the isolation structure around the green light-emitting element is increased compared with the previous one during the light-emitting process, thereby reducing the light-emitting angle and the light-emitting range, thereby reducing the brightness corresponding to the green light-emitting element in the display panel, reducing the brightness difference between the green light-emitting element and other light-emitting elements, and balancing the light-emitting brightness of the entire display panel.

[0060] In a possible example, a projection pattern of the first touch electrode film layer in the orthographic projection direction is a closed pattern or a non-closed pattern.

[0061] In a possible example, when the first touch electrode film layer in the first isolation structure constitutes a non-enclosed structure, a ratio between an area of ​​a projection pattern of the first touch electrode film layer and an area of ​​a projection pattern of the first isolation structure is greater than a first preset ratio.

[0062] In a possible example, a side of the green light emitting element away from the substrate is a pixel opening area. A first orthographic projection of a boundary of the first touch electrode film layer close to the pixel opening area on the substrate overlaps with a boundary of a second orthographic projection of the pixel opening area on the substrate, or the first orthographic projection is within the second orthographic projection.

[0063] In a possible example, when the first orthographic projection is within the second orthographic projection, the ratio of the overlapping area of ​​the first orthographic projection and the second orthographic projection to the second orthographic projection is less than or equal to a preset ratio; the preset ratio enables the light of the light-emitting element to be transmitted from the pixel opening area corresponding to the green light-emitting element at a preset angle.

[0064] In a possible example, the preset ratio is 4%.

[0065] In a possible example, the first isolation structure includes: a touch buffer film layer on one side of the pixel definition layer, the first touch electrode film layer arranged on the side of the touch buffer film layer away from the pixel definition layer, the insulating film layer arranged on the side of the first touch electrode film layer away from the pixel definition layer, and the second touch electrode film layer arranged on the side of the insulating film layer away from the pixel definition layer; the insulating film layer and the touch buffer film layer are transparent film layers.
