Abstract
Description
Technical Field
[0001] The present invention generally relates to the field of display technology, and more particularly to a display panel and a display device. Background Art
[0002] Due to the restrictions of flexible folding, narrow frame and other product requirements, the touch structure layer of OLED adopts a flexible multi-layer surface covering (Flexible Multi Layer On Cell, FMLOC) structure. The flexible touch structure layer is arranged on the encapsulation layer of the OLED backplane, which has the advantages of being light, thin and foldable. Based on the considerations of reducing resistance and improving sensitivity, the electrodes in the touch structure layer adopt the form of metal mesh 10 (Metal Mesh). Compared with the use of transparent conductive materials (such as Indium Tin Oxide, ITO for short) to form touch electrodes, the metal mesh 10 has the advantages of low resistance, small thickness and fast response speed. Considering the thinning of the product and the increase of capacitive load, a single-layer metal mesh 10 will be designed as FSLOC (Flexible Single Layer On Cell) structure.
[0003] FMLOC metal grid is generally prepared by Ti / Al / Ti material, and the formed metal grid pattern can be selected according to actual needs. However, due to process conditions around the holes of OLED FMLOC products, the actual line width of the FMLOC metal grid deviates from the designed line width around the holes. Due to the limitations of process conditions around the holes, the actually prepared line width will be slightly smaller than the designed line width. In order to avoid this line width difference, CD compensation design is made (i.e., in the area around the holes). However, under dark strong reflected light conditions, the area with CD compensation design and the area without CD compensation design (normal area) will have optical defects with obvious boundaries between light and dark partitions.
[0004] This optical defect with obvious boundaries between bright and dark partitions is caused by the metal grid blocking the anode reflection at the side angle. Figure 1 In the test method on the right, the side light is about 45°, and the human eye observes at about 135°. It can be seen that the optical reflection is obviously poor at the boundary between the bright and dark partitions, forming a Figure 1 The situation shown on the left. Summary of the invention
[0005] In view of the above defects or shortcomings in the prior art, it is desirable to provide a display panel and a display device.
[0006] In a first aspect, a display panel is provided, comprising a perforated area, a hole peripheral area and other areas, wherein the hole peripheral area is arranged around the perforated area, and the other area is an area of the display panel other than the perforated area and the hole peripheral area.
[0007] The display panel includes a touch metal layer, the touch metal layer includes staggered metal grids, and the width of the metal grid lines of the touch metal layer in the area surrounding the hole is greater than the width of the metal grid lines in other areas;
[0008] The hole peripheral area includes at least two compensation areas, and the line widths of the metal grids in adjacent compensation areas are different and both are greater than the line widths of the metal grids in other areas.
[0009] In a second aspect, a display device is provided, comprising the above-mentioned display panel, wherein a photosensitive device is provided on the display panel, and the photosensitive device is arranged in a perforated area.
[0010] According to the technical solution provided in the embodiment of the present application, by setting at least two compensation areas in the hole peripheral area on the display panel, the metal grid width of the compensation area is set to be greater than the metal grid width of other areas, and the metal grid line width of the hole peripheral area is adjusted and compensated by setting the compensation area. The metal grid prevents the optically undesirable phenomenon of dark state reflection from occurring between the compensated hole peripheral area and other areas, thereby making the display of the display panel uniform in brightness.

[0020] 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.
[0021] 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 present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0022] Please refer to Figures 3 to 5 , Figure 8 As shown, this embodiment provides a display panel, including a perforated area 1, a hole peripheral area 2 and other areas 3, wherein the hole peripheral area 2 is arranged around the perforated area 1, and the other area 3 is an area of the display panel other than the perforated area 1 and the hole peripheral area 2.
[0023] The display panel includes a touch metal layer, the touch metal layer includes staggered metal grids 10, and the line width of the metal grids 10 of the touch metal layer located in the hole peripheral area 2 is greater than the line width of the metal grids 10 in the other areas 3;
[0024] The hole peripheral area 2 includes at least two first compensation areas 5 , and the line widths of the metal grids 10 in adjacent first compensation areas 5 are different and both are larger than the line widths of the metal grids 10 in the other areas 3 .
[0025] In the present embodiment, at least two compensation areas are set in the hole peripheral area 2 on the display panel, and the width of the metal grid 10 in the compensation area is set to be greater than the width of the metal grid 10 in other areas. The line width of the metal grid 10 in the hole peripheral area 2 is adjusted and compensated by setting the compensation area. The metal grid 10 prevents the optical adverse phenomenon of dark state reflection from occurring between the compensated hole peripheral area 2 and other areas 3, so that the display of the display panel is uniform in brightness.
[0026] The display panel provided in this embodiment is divided into three parts according to the positions of the openings on the display panel. Figures 3 to 5 As shown, they are respectively a punching area 1, which is determined according to the punching position, and a hole peripheral area 2, which is arranged around the punching area 1. Generally, a position extending 3 mm from the edge of the punching area 1 in the direction away from the hole is the hole peripheral area 2. The positions on the display panel except the punching area 1 and the hole peripheral area 2 are all other areas 3;
[0027] The touch metal layer on the display panel is realized by criss-crossing metal grids 10, and the metal grids 10 are distributed in other areas 3 and the hole peripheral area 2 on the display panel. However, due to the limitation of the manufacturing process, the line width of the metal grid 10 in the hole peripheral area 2 is smaller than the line width of the metal grid 10 in other areas 3. Therefore, in this embodiment, a compensation area is set in the hole peripheral area 2, and the line width of the metal grid 10 in the compensation area of the hole peripheral area 2 is increased, so that the compensated structure will not have uneven brightness when displayed; the number of compensation areas divided into the hole peripheral area includes at least two, and the line widths of the metal grids 10 in the two compensation areas must be compensated, and are set to be larger than the line widths of other areas, so that the line width of the entire hole peripheral area can be compensated.
[0028] Preferably, the hole peripheral area includes a plurality of compensation areas, and the difference between the line width of the metal mesh 10 in each compensation area and the line width of the metal mesh 10 in other areas is less than or equal to 0.7 micrometers.
[0029] In order to ensure that the brightness of the area around the hole 2 in the present embodiment is relatively uniform in the dark state display and to ensure the compensation effect of the compensation part, the area around the hole 2 is divided into a plurality of compensation areas, and the plurality of compensation areas include the first compensation area 5 mentioned above. A corresponding compensation part is arranged in each compensation area, and the width of the compensation parts in different compensation areas is different according to the different positions of the compensation areas. After the corresponding compensation of each area, the entire display panel will not have uneven brightness in the dark state.
[0030] In the present embodiment, the FMLOC metal grid 10 is arranged at the position of the hole peripheral area. Due to the limitation of the process conditions, the line width of the metal grid 10 actually formed is insufficient. Therefore, it is necessary to make a certain compensation in the hole peripheral area so that the line width of the metal grid 10 in the hole peripheral area exceeds the line width of the metal grid 10 in other areas, so as to ensure that there is enough margin in the preparation process of the FMLOC metal grid 10 and ensure that the metal grid 10 realizes the effect of the touch function; Figure 2 As shown, the left figure shows the incident and emitted light without compensation. Figure 1 The test method shown on the right is used for testing. The incident light is incident on the display panel at an angle of 60° to the normal line. A metal grid with 10 lines is set at the position of the incident angle. After the light enters the display panel, it is reflected by the anode layer to form Figure 2 The outgoing light shown on the left;
[0031] In order to ensure the width of the metal grid 10 lines, some compensation is required, such as Figure 2The right side shows the direction of the corresponding light after the compensation width is set next to the metal grid 10 lines. A metal line of a certain width is added at the position of the incident angle of the radiation light. When the incident light of the same angle enters the display panel, the metal grid 10 lines will block the incident light to a certain extent. Therefore, the light reflected by the anode layer will also decrease. The corresponding position is relative to Figure 2 The situation on the left side will be a dark state. Therefore, it is necessary to reasonably set the compensation metal line width so that the position of the compensated metal grid 10 will not have obvious uneven brightness compared with other areas.
[0032] This embodiment provides a method of changing the line width of the metal grid 10 in the hole peripheral area 2 to reduce the optical non-uniformity caused by the metal grid 10 blocking the anode reflection. According to simulation calculations, when the difference between the line width of the metal grid 10 in the compensation area of the hole peripheral area 2 and the line width of the metal grid 10 in other areas does not exceed 0.7 microns, the problem of optical non-uniformity can be solved. When it exceeds 0.7 microns, uneven brightness and darkness will occur. Therefore, it is preferred to set the width of the compensation part not to exceed 0.7 microns. Figure 6 and Figure 7 As shown in the figure, the optical conditions of the metal grid 10 line width difference of 0.7 and 0.8 in this embodiment are shown. When the line width difference exceeds 0.8 microns, obvious bright and dark partition phenomenon will appear. Therefore, it is preferred to set the difference between the line width of the metal grid 10 in each compensation area and the line width of the metal grid 10 in other areas to not more than 0.7 microns, so that Figure 7 The situation on the center right will not occur.
[0033] Furthermore, the difference between the line widths of the metal grids 10 in any two adjacent compensation areas is less than or equal to 0.7 micrometers.
[0034] In the present embodiment, the difference between the line width of the metal grid 10 in the compensation area and the line width of the metal grid 10 in other areas is limited to less than or equal to 0.7 microns. At the same time, the line widths in the compensation areas are not completely the same, and adjacent compensation areas also need to be controlled to avoid uneven brightness. Therefore, the line width of the metal grid 10 between adjacent compensation areas is the same as in the above embodiment, and the line width difference is controlled within 0.7 microns. Based on the reasons in the above embodiment, the compensation area controlled within this range can realize the normal display of the above display panel without the function of bright and dark partitions.
[0035] Furthermore, the difference between the line widths of the metal grids 10 in any two adjacent compensation areas is less than or equal to 0.2 micrometers.
[0036] See also Figures 3 to 5As shown, the present embodiment provides a variety of compensation area division schemes. In order to ensure that the line width difference between adjacent compensation areas is small and there is no obvious uneven brightness, the line width difference of the metal grid 10 of adjacent compensation areas is preferably set to be less than or equal to 0.2 microns. Therefore, when multiple compensation areas are set in the area surrounding the hole, the line width difference between adjacent compensation areas is also small, and the brightness difference between adjacent compensation areas is also small. Therefore, the uneven brightness of the display panel can be better improved.
[0037] Furthermore, the multiple compensation areas include a first compensation area 5 and a second compensation area 4 , the second compensation area 4 is closer to the other areas than the first compensation area 5 , and the line width of the metal grid 10 of the first compensation area 5 is greater than the line width of the metal grid 10 of the second compensation area 4 .
[0038] Specifically, a compensation zone is set in the hole peripheral area 2 to achieve a change in the line width of the metal grid 10, which requires regional division. A relatively obvious light and dark partition appears in the middle part of the lower part of the hole peripheral area 2 near other areas 3. Therefore, at least a compensation zone needs to be set in this area to compensate for the line width of the metal grid 10 to a certain extent. Preferably, a first compensation zone 5 and a second compensation zone 4 are set, wherein the lower part of the hole peripheral area 2 near other areas 3 is set as the second compensation zone 4, and the first compensation zone 5 compensates for the line width of the metal grid 10 in the second compensation zone, so that the brightness of the display panel is more uniform when the display is in a dark state.
[0039] In the present embodiment, at least two compensation zones are set in the hole peripheral area 2. The compensation zone is set at the position where the uneven brightness is most obvious, that is, the middle part of the lower part of the hole peripheral area 2 close to other areas 3. The difference between the position of the compensation zone and the line width of the metal grid 10 in other areas is the smallest, so that it has the best compensation effect. When setting the compensation part in the hole peripheral area 2, the entire hole peripheral area 2 can be preferably divided into a first compensation zone 5 and a second compensation zone. It can also be divided into multiple different compensation zones according to the situation, and compensation values of different widths are used for compensation. However, no matter how many compensation zones are set, it is preferred to set the difference between the line width of the metal grid 10 in the first compensation zone 5 and the line width of the metal grid 10 in other zones to the minimum, so that this position has a better improvement effect.
[0040] Furthermore, the hole peripheral area 2 is divided into a plurality of compensation areas in the first direction of the display panel, and the line width of the metal grid 10 in the compensation area gradually increases in the direction away from the other areas 4 .
[0041] like Figure 3As shown, this embodiment provides a compensation zone division method, wherein the display panel is divided into zones in a first direction, where the first direction refers to the Y-axis direction shown in the figure, and each zone extends along the X-axis to form a plurality of zones parallel to the X-axis. The number of zones can be determined according to the size of the actual display panel. Preferably, at least three compensation zones are set in the hole peripheral zone 2. The more compensation zones there are, the more gradually the brightness will change, the less obvious the distinction between light and dark between the compensated zones will be, the better the compensation effect will be, and there will be no optical unevenness on the display panel. Generally, when the process conditions are not restricted, 3-7 lateral compensation zones are set.
[0042] In this embodiment, six compensation areas are preferably set, and the partitioning method can be that each lateral small area is evenly distributed in the partition direction, such as Figure 3 The B, C, D, E, F, and G shown are small lateral areas with evenly distributed sizes. Each small lateral area may also be moved up or down in the partition direction according to the process conditions and not evenly distributed in size. The width of each compensation area in the first direction is preferably set to the same width, and considering the limitation of the process conditions of the hole peripheral area 2, during the design and preparation, the line width of the compensation area is set to be larger than the line width of the A area (i.e., the other area 3). This design compensates for the limitation of the process conditions, so that there is no large difference between the line widths of the hole peripheral area 2 and the other areas 3 on the prepared display panel, and the line width difference at the boundary of each compensation area is less than or equal to 0.7um. Figure 2 The line width of the metal grid 10 in the small lateral areas B, C, D, E, F, and G is set to be gradually larger than the line width in area A, which achieves the best effect of eliminating optical unevenness. For example, the difference in the line width of the metal grid 10 is set to 0.1um, 0.2um, 0.3um, 0.4um, 0.5um, and 0.6um, respectively.
[0043] Furthermore, the hole peripheral area 2 is divided into a plurality of compensation areas in the second direction of the display panel, and the line width of the metal grid 10 of the compensation area gradually increases from the middle of the hole peripheral area to both ends.
[0044] like Figure 4As shown, the present embodiment provides another way of dividing the compensation zone, wherein the display panel is divided into zones in the second direction, and each compensation zone is arranged vertically. The second direction mentioned here refers to the X-axis direction shown in the figure, and each zone extends along the Y-axis to form a plurality of zones perpendicular to the X-axis. The number of zones can be determined according to the size of the actual display panel. Preferably, at least three compensation zones are arranged in the hole peripheral zone 2. The more compensation zones there are, the less obvious the distinction between light and dark between the compensated zones is, the better the compensation effect is, and no optical non-uniformity will occur on the display panel. Generally, when the process conditions are not restricted, 3-7 vertical compensation zones are arranged.
[0045] In this embodiment, three compensation areas are preferably set. The partitioning method can be that each vertical small area is allocated a size in the partitioning direction. Preferably, the width of each compensation area in the second direction is set to be the same width, such as Figure 3 B, C, and D are small vertical areas with evenly distributed sizes. Each small vertical area can also be moved left or right in the partition direction according to the process conditions and with uneven distribution sizes. Similar to the above-mentioned horizontal partitioning, considering the limitations of process conditions, it is preferred to set the line width of the partition to be larger than the line width of area A (i.e., other areas 3) during design, and the line width difference at the boundary is less than or equal to 0.7um. Figure 4 The line width of the metal grid 10 in the vertical small area is set to increase from the center position C area to the two sides B and D areas in sequence, which achieves the best effect of eliminating optical unevenness. For example, the difference in the line width of the metal grid 10 is set to 0.4um, 0.2um, and 0.4um in the B, C, and D areas, respectively.
[0046] Furthermore, the plurality of compensation areas are divided into a grid shape, the line width of the metal grid 10 of the compensation area gradually increases in the direction away from the other areas 3, and the line width of the metal grid 10 of the compensation area gradually increases from the middle of the hole peripheral area to both ends.
[0047] like Figure 5 As shown, this embodiment also provides a method for dividing the compensation area, wherein the division is performed in a grid-like form, wherein the horizontal division can be similar to the above embodiment, with at least 3 partitions being set, and the vertical division can also be similar to the above embodiment, with at least three partitions being set, generally within the range of 3-9 under the condition that the process is not restricted.
[0048] In this embodiment, 9 compensation areas are preferably set, and the partitioning method can be that each horizontal or vertical small area is evenly distributed in the partition direction, such as Figure 4B, C, D, E, F, G, H, I, and J are grid small areas with evenly distributed sizes. It is also possible that each horizontal (or vertical) small area moves up or down (left or right) in the partition direction according to the process conditions and has an uneven distribution size. Similar to the above partition situation, considering the limitations of process conditions, it is preferred to make the line width of the partition larger than the line width of the A area during design, and the line width difference at the boundary is less than or equal to 0.7um. Figure 5 The line width of the metal grid 10 in the small grid area is set to increase from bottom to top and from the center to the left and right sides, which achieves the best effect of eliminating optical unevenness. For example, the difference in the line width of the metal grid 10 such as B, C, D, E, F, G, H, I, and J areas is set to: 0.4um, 0.3um, 0.4um, 0.3um, 0.2um, 0.3um, 0.2um, 0.1um, and 0.2um, respectively.
[0049] In this embodiment, three compensation areas arranged vertically are taken as an example, in which a schematic diagram of the metal grid of the touch metal layer is shown, in which the grid is illustrated only with staggered lines, and the specific grid is not completely straight, and the diamond structures formed between them are not completely the same or regular, which are adjusted according to the arrangement of pixels; wherein, the metal grid line widths of various compensation areas are not completely the same, and the line widths are all larger than the metal grid line widths of other areas, and the compensation area in the middle has the smallest difference in metal grid line width with other areas, and extends to both sides, and the difference in metal grid line width with other areas increases, so that the formed metal grid line is wider.
[0050] Furthermore, the display panel includes a display layer and a touch structure layer disposed on the display layer, and the touch structure layer includes the touch metal layer.
[0051] like Fig. 9 As shown, the display panel in this embodiment includes a display layer, which refers to a substrate, a gate layer, an active layer, a source and drain layer, an anode layer, etc. arranged on the substrate to form a thin film transistor structure to form a backplane of the display panel, a light-emitting layer structure is formed on the backplane and packaged, and an FMLOC film layer, i.e., a touch structure layer, is formed on the packaged structure, wherein the touch structure layer includes the touch metal layer mentioned in the above embodiment.
[0052] The touch metal layer includes a staggered metal grid 10, including TX lines and RX lines, such as Fig.10 As shown, a touch insulating layer is arranged below the metal grid 10, and RX is connected via a bridge structure arranged in the touch insulating layer. The line width of the metal grid 10 mentioned in the above embodiment refers to the line width of the TX line and the RX line therein.
[0053] The display panel provided in this embodiment divides the line width of the metal grid 10 in the hole peripheral area 2 into zones, and compensates for the line width of the metal grid 10 in the hole peripheral area 2 by the zones, thereby alleviating the phenomenon of optical non-uniformity of dark state reflection caused by the metal grid 10 blocking the anode reflection, and limiting the line width of the metal grid 10 line compensation, so that the compensation area is divided within a more appropriate range.
[0054] Based on the same inventive concept, this embodiment further provides a display device, including the above-mentioned display panel, on which a photosensitive device is provided, and the photosensitive device is arranged in the perforated area. In this embodiment, a corresponding photosensitive device, such as a camera or the like, is arranged in the perforated area of the display device.
