[0044] Application Overview

[0045] In display devices such as OLED, especially in AMOLED (Active-Matrix Organic Light-Emitting Diode) display devices, there is a phenomenon that as the observation angle increases, the brightness gradually decreases and the color deviates (relative to the normal viewing angle (the angle between the line of sight and the vertical direction of the display, etc.), that is, when the viewing angle is 0°). This color deviation is usually expressed as color deviation, and the unit is JNCD (Just Notable Color Difference), that is, the color deviation is a multiple of the color deviation that can be distinguished by the human eye. Usually, the color deviation specifications of AMOLED products at different angles are different. The typical color deviation specifications are <4JNCD at a 30° viewing angle, <5JNCD at a 45° viewing angle, and <7JNCD at a 60° viewing angle. In addition to color deviation at different observation angles, there is also color deviation in different observation directions, such as Figure 1 As shown, the observation angles φ are set to 0° and 180° when the user observes from both sides of the long side of the display device, and 90° and 270° when the user observes from both sides of the short side of the display device.

[0046] Obtained through inventor testing Figure 2 and Figure 3 , Figure 2 and Figure 3 They are the JNCD curves of white light in different observation directions (the horizontal axis is the viewing angle, the vertical axis is the color deviation JNCD) and the △JNCD of white light in different observation directions max (Maximum color shift difference) curve (the horizontal axis is the viewing angle, the vertical axis is the maximum color shift difference △JNCD), through Figure 2 and Figure 3 It can be found that the color deviation difference in different observation directions can reach 1.5JNCD at a 60° viewing angle, which can already cause sensory differences in users. Through research, it was found that the reasons for this difference may include the flatness of the anode and the design of the wiring in the touch electrode. Among them, the metal wiring in the touch electrode has a blocking effect on the pixel light at a large viewing angle, which will accelerate the viewing angle brightness attenuation at a large viewing angle. In display devices such as OLED, due to the different sizes of pixels in different directions, the wiring in the touch electrode may have different blocking effects on the pixels in different observation directions, thereby resulting in color deviation differences in different observation directions. Especially in such as Figure 4 The asymmetric arrangement of pixels shown ( Figure 4 In a display device (where the differently sized, filled boxes represent different types of pixels, the wiring between the pixels is the metal wiring that constitutes the touch electrode, and the arrangement of pixels of different colors is not symmetrical about the extension direction of the long side or short side of the display device), this color deviation difference in different observation directions is more serious.

[0047] The inventors further analyzed the reasons for the color cast differences in different observation directions and found that Figure 5 , Figure 5 The upper middle picture is a top-down view of the pixel and the surrounding metal traces. Figure 5 The middle figure is a cross-sectional view of the above figure along line AA'. Figure 5 The figure below is a schematic cross-sectional view along line BB' of the figure above. Taking a rectangular pixel as an example, the pixel is surrounded by the metal traces of the touch electrode. Although the distances between the four sides of the pixel and the adjacent touch electrodes are the same, when the observation direction is 90° and 270°, the ratio of the metal trace width L1 of the touch electrode to the pixel size L3 is larger (i.e., L1 / L3> L1 / L2), resulting in more severe light blocking, which causes different color shifts when viewed from different directions.

[0048] Based on the above research, the inventor reduced the light blocking of the first pixel in the second direction by the electrode lines (second touch electrode lines) on both sides of the short side extension direction of the first pixel (the second direction) by arranging the electrode lines (second touch electrode lines) on both sides of the short side extension direction of the first pixel relatively far away from the first pixel, so that the light blocking conditions of the first pixel in the first direction and the second direction are similar, thereby improving the problem of inconsistent color deviation of the display device in different observation directions.

[0049] Based on the above ideas, a display device provided in an embodiment of the present application is formed. The display device provided in an embodiment of the present application will be exemplarily described below with reference to the accompanying drawings.

[0050] Exemplary devices

[0051] The embodiment of the present application provides a display device, such as Figure 6 , Figure 7(a), Figure 7(b) and Figure 8 As shown, Figure 6 FIG7 is a schematic diagram of the cross-sectional structure of the display device, FIG7(a) and FIG7(b) are schematic diagrams of the top view of the display device, Figure 8 The upper figure is a cross-sectional schematic diagram along the CC' line in Figure 7(a). Figure 8 The lower figure is a cross-sectional schematic diagram along line DD' in FIG. 7( a ), wherein the display device includes:

[0052] substrate 10;

[0053] A pixel definition layer 20 located on one side of the substrate 10 , wherein the pixel definition layer 20 includes a first opening 21 ;

[0054] a first pixel 31 located in the first opening 21;

[0055] The touch electrode located on the side of the first pixel 31 away from the substrate 10 includes a first touch electrode line 41 extending in the second direction DR2 and a second touch electrode line 42 extending in the first direction DR1. The first direction DR1 and the second direction DR2 intersect. The first pixel 31 includes a long side extending in the first direction DR1 and a short side extending in the second direction DR2. The distance between the orthographic projection of the short side of the first pixel 31 on the substrate 10 and the orthographic projection of the first touch electrode line 41 adjacent to the short side on the substrate 10 is D1. The distance between the orthographic projection of the long side of the first pixel 31 on the substrate 10 and the orthographic projection of the second touch electrode line 42 adjacent to the long side on the substrate 10 is D2, and 1<D2 / D1≤5.

[0056] It is easy to understand that, in addition to the pixel definition layer 20, the substrate 10, and the first pixel 31, the display device may also include a pixel driving circuit composed of a thin film transistor, other pixels for emitting light of different colors in addition to the first pixel 31, and structures such as the gate, drain, source, and active layer of the thin film transistor. In order to clearly illustrate the positional relationship between the first touch electrode line 41, the second touch electrode line 42, and the first pixel 31, Figures 6 to 8 Other structures that may be provided in the display device except the pixel definition layer 20, the substrate 10 and the first pixel 31 are not shown.

[0057] In addition, in the display device, the number of the first pixels 31 is usually multiple. Figures 6 to 8 In order to clearly illustrate the positional relationship between the structures, only one first pixel 31 is shown, but the number of first pixels 31 in the display device is not limited.

[0058] In this specification, the first pixel 31 may refer to a pixel for emitting light of a certain color. In addition to the first pixel 31, the display device may also be provided with pixels for emitting light of other colors. In one exemplary embodiment of this specification, the first pixel 31 and the pixels for emitting light of other colors are at least partially arranged asymmetrically to meet the pixel arrangement requirements of a specific type of display device.

[0059] The first opening 21 of the pixel definition layer 20 is an opening for setting the first pixel 31. Figure 6 As shown, in some cases, the opening area of ​​the pixel definition layer 20 may be larger than the actual setting area of ​​the first pixel 31 . In this case, the opening area of ​​the pixel definition layer 20 includes the first opening 21 .

[0060] The metal traces of the touch electrodes (i.e., first touch electrode lines 41 and second touch electrode lines 42) are typically arranged around the openings of the pixel definition layer 20 to prevent the metal traces from blocking light from the pixels. Multiple metal traces are interconnected to form a mesh of electrodes, which are the touch electrodes. Adjacent touch electrodes can also be electrically connected via the metal traces between the touch electrodes.

[0061] Figures 7(a) and 7(b) illustrate two methods for making the first distance D1 smaller than the second distance D2. In one embodiment, as shown in Figure 7(a), the orthographic projection of the entire second touch electrode line 42 on the substrate 10 is at a greater distance from the orthographic projection of the first opening 21 on the substrate 10, such that the second distance D2 can be greater than the first distance D1. In another embodiment, as shown in Figure 7(b), the second touch electrode line 42 includes a raised portion 42a that protrudes toward a side away from the first pixel, meaning that the orthographic projection of a portion of the second touch electrode line 42 on the substrate 10 is at a greater distance from the orthographic projection of the first opening 21 on the substrate 10. Optionally, the portion of the second touch electrode line 42 at a greater distance from the orthographic projection of the first opening 21 on the substrate 10 can be aligned with the first opening 21 in the second direction.

[0062] In this embodiment, the display device reduces light shielding from the first pixel 31 in the second direction DR2 by disposing the electrode lines (second touch electrode lines 42) on both sides of the short side of the first pixel 31 relatively far away from the first pixel 31. This reduces light shielding from the first pixel 31 in the second direction DR2 by the electrode lines (second touch electrode lines 42) on both sides of the short side of the first pixel 31. This makes the light shielding from the first pixel 31 in the first direction DR1 and the second direction DR2 similar, thereby improving the problem of inconsistent color shift in different viewing directions of the display device. Furthermore, the inventors have discovered through research that when 1 < D2 / D1 ≤ 5, the problem of different color shifts of the first pixel in different viewing directions can be effectively improved while not affecting the arrangement of other pixels.

[0063] In addition, in this embodiment, the requirement that the first distance D1 is smaller than the second distance D2 can be met by adjusting the positional relationship between the second touch electrode line 42 and the first pixel 31. There is no need to adjust other pixel arrangements and electrode line settings, and the overall structure of the display device is only slightly modified, which has the advantage of being easy to implement.

[0064] In an exemplary embodiment of this specification, Figure 9 As shown, the pixel definition layer 20 further includes a second opening 22;

[0065] The display device further includes: a second pixel 32 or a third pixel 33 located in the second opening 22; the first pixel 31, the second pixel 32, and the third pixel 33 are configured to emit light of different colors; the first opening has the same shape as the first pixel located in the first opening; the second opening has the same shape as the second pixel or the third pixel located in the second opening; and the aspect ratio of the first opening 21 is greater than the aspect ratio of the second opening 22;

[0066] The touch electrode further includes a third touch electrode line 43 located at one side of the second opening 22 . The third touch electrode line 43 is electrically connected to the first touch electrode line 41 and the second touch electrode line 42 .

[0067] The first pixel 31, the second pixel 32, and the third pixel 33 can be pixels for emitting light of different colors, for example, pixels for emitting red light, green light, and blue light, respectively. In this embodiment, the aspect ratio of the first opening 21 is larger than that of the second opening 22. Accordingly, the aspect ratio of the first pixel 31 disposed in the first opening 21 is also larger than that of the second pixel 32 or the third pixel 33 disposed in the second opening 22. Pixels with larger aspect ratios have more severe color shift in different observation directions. Therefore, by adjusting the distance between the electrode lines on both sides of the first opening 21 and the first opening 21, light output from the first pixel 31 with severe color shift in different observation directions can be adjusted, thereby significantly improving the color shift of the display device as a whole in different observation directions. In some embodiments, considering that the lifespan of pixels for emitting red light is higher, while the lifespan of pixels for emitting blue light is lower, therefore, in general, the size of red light pixels is smaller and the aspect ratio is higher, and the size of blue light pixels is larger and the aspect ratio is smaller. Therefore, optionally, the first pixel 31 can be used to emit red light, and the second pixel 32 and the third pixel 33 can be used to emit green light and blue light, respectively.

[0068] In addition, when the overall design of the display device does not allow changes to the pixel arrangement, as described above, the first distance D1 and the second distance D2 can be met by simply adjusting the distance between the second touch electrode line 42 and the first opening 21, without redesigning the pixel arrangement. The overall solution is simple, easy to implement, and easy to implement.

[0069] In other embodiments of the present specification, some feasible methods are also used to assist in improving the light shielding of the first pixel 31 in the second direction DR2 by the second touch electrode line 42. In a feasible embodiment, the second touch electrode line is disconnected corresponding to the first pixel, for example, referring to Figure 10The second touch electrode line 42 includes a first notch 44 and two first sub-electrode lines 421 separated by the first notch 44 .

[0070] In this embodiment, although the first notch 44 divides the second touch electrode line 42 into two sections, Figure 10 As shown, since a touch electrode is a mesh electrode composed of touch electrode lines distributed around multiple pixels and connected to each other, even if the second touch electrode line corresponding to the first pixel is disconnected, there are still touch electrode lines 43 located around other pixels connected to the disconnected second touch electrode line. When in use, touch signals can be provided to the disconnected second touch electrode line through these touch electrode lines 43. When the second touch electrode line senses the position of the operating body, the charge change can also be transmitted to the drive circuit through these touch electrode lines 43, so that the second touch electrode line can be used as part of the touch capacitor plate to transmit charge, thereby detecting the position of the operating body (such as a finger). That is, due to the electrical connection between the touch electrode lines 43 located around other pixels and the second touch electrode line 42, the second touch electrode line 42 that is broken into two sections can still be used as part of the touch electrode. In this way, without affecting the function of the second touch electrode line 42, the second touch electrode line 42 is divided into two sections by the first notch 44, thereby weakening the light blocking of the second touch electrode line 42 to the first pixel 31 in the second direction DR2, thereby improving the color shift phenomenon of the display device in different observation directions.

[0071] For example, refer to Figure 11 , Figure 11 This is an enlarged schematic diagram of the second touch electrode line 42. The second touch electrode line 42 includes a first electrode line body 42' and a plurality of through holes 422 that penetrate the first electrode line body 42'. By providing the through holes 422, the light emitted from the first pixel 31 in the second direction DR2 can be emitted through the through holes 422, thereby reducing the light shading of the first pixel 31 in the second direction DR2 by the second touch electrode line 42, thereby improving the color shift phenomenon of the display device in different observation directions. In some embodiments, such as Figure 11 As shown, the through hole 422 does not disconnect the second touch electrode line 42 as the first notch 44 does, which helps to ensure the signal transmission performance of the second touch electrode line 42 .

[0072] For example, refer to Figure 12 The width of the second touch electrode line 42 is smaller than that of the first touch electrode line 41. That is, by appropriately reducing the width of the second touch electrode line 42, the light shielding of the first pixel 31 in the second direction DR2 caused by the second touch electrode line 42 can be weakened, thereby improving the color shift phenomenon of the display device in different observation directions.

[0073] In some embodiments, the first electrodes on both sides of the long side extension direction of the first pixel 31 (i.e., the first direction DR1) may also cause color deviation in different observation directions (e.g., on both sides of the first direction DR1) due to the setting position of the first pixel 31. For example, in the display device of the prior art, the distance between the first pixel 31 and the first electrodes on both sides of the first direction DR1 is different, which will cause the first electrodes on both sides of the first direction DR1 to block the light of the first pixel 31 in these two observation directions differently, which may cause a certain color deviation when the user observes the display device in these two directions. In order to improve this problem, in one embodiment of the present specification, as Figure 13 As shown, the first touch electrode lines 41 include a first type of electrode line 411 and a second type of electrode line 412 respectively located on both sides of the short side of the first pixel. The width of the first type of electrode line 411 is greater than that of the second type of electrode line 412.

[0074] The distance between the orthographic projection of one short side of the first pixel on the substrate and the orthographic projection of the first type of electrode line adjacent to the short side on the substrate is D3, and the distance between the orthographic projection of the other short side of the first pixel on the substrate and the orthographic projection of the second type of electrode line adjacent to the short side on the substrate is D4, D3=D4.

[0075] In this embodiment, by increasing the width of the first type of electrode lines 411 so that the third distance D3 and the fourth distance D4 are equal, the first touch electrode lines 41 provide the same light shielding to both sides of the first pixel 31 in the first direction DR1, thereby improving the above-mentioned problem. Optionally, the width of the first type of electrode lines 411 can be increased by configuring the first type of electrode lines 411 to include at least two second sub-electrode lines 4111 arranged side by side.

[0076] Similar to the arrangement of the first notch 44 and the through hole 422 in the second touch electrode line 42 to improve the shielding of the first pixel 31 by the electrode line in a certain direction, in some embodiments of the present specification, for example, Figure 14 As shown, the first type electrode line 411 includes a second notch 45 and two second sub-electrode lines 4111 separated by the second notch 45;

[0077] Alternatively, as Figure 15 As shown, a plurality of through holes 422 are provided through the first type electrode wire 411 .

[0078] Correspondingly, such as Figure 16 As shown, an embodiment of this specification further provides an electronic device 100, including: a display device as described in any of the above embodiments.

[0079] In summary, the embodiments of the present application provide a display device and an electronic device, wherein the display device reduces the light blocking of the first pixel in the second direction by the electrode lines (second touch electrode lines) on both sides of the short side extension direction of the first pixel (the second direction) by arranging the electrode lines (second touch electrode lines) on both sides of the short side extension direction of the first pixel (the second direction) relatively far away from the first pixel, so that the light blocking conditions of the first pixel in the first direction and the second direction are similar, thereby improving the problem of inconsistent color deviation of the display device in different observation directions.
