[0071] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0072] In related technologies, because the amount of light emitted by different light-emitting units may be different, the display module may have color shift in different directions, resulting in poor display effect.

[0073] Figure 1 is a schematic diagram of a display module provided in an embodiment of this application. Referring to Figure 1, the display module 100 includes: a substrate 101, a plurality of pixel units 102, and a light modulation layer 103.

[0074] Figure 2 is a top view of a substrate according to an embodiment of this application. Referring to Figure 2, the substrate 101 includes a display area 101a and a peripheral area 101b surrounding the display area 101a. Figure 3 is a partial top view of a display module according to an embodiment of this application. Referring to Figures 1 to 3, a plurality of pixel units 102 are located on one side of the substrate 101 and within the display area 101a. The plurality of pixel units 102 includes a plurality of first pixel units 102a and a plurality of second pixel units 102b. The first pixel units 102a and the second pixel units 102b are arranged adjacent to each other.

[0075] Referring to Figures 1 and 3, the light modulation layer 103 is located on the side of the plurality of pixel units 102 away from the substrate 101, and the light modulation layer 103 includes a target modulation structure 1031. The orthographic projection of the target modulation structure 1031 on the substrate 101 is located between the orthographic projections of the first pixel unit 102a and the second pixel unit 102b on the substrate 101. The distance d1 between the orthographic projection d1 of the target modulation structure 1031 and the orthographic projection d2 of the first pixel unit 102a on the substrate 101 is smaller than the distance d2 between the orthographic projections d2 of the target modulation structure 1031 and the second pixel unit 102b on the substrate 101.

[0076] In this embodiment, the light modulation layer 103 can be used to modulate the light emitted by the pixel unit 102. Since the distance d1 between the target modulation structure 1031 and the first pixel unit 102a in the light modulation layer 103 is small, and the distance d2 between the second pixel unit 102b is large, the target modulation structure 1031 can be used to modulate the light emitted by the first pixel unit 102a without significantly affecting the light emitted by the second pixel unit 102b.

[0077] Furthermore, since the target modulation structure 1031 is located between the first pixel unit 102a and the second pixel unit 102b, a portion of the light emitted from the first pixel unit 102a that is directed towards the second pixel unit 102b can illuminate the target modulation structure 1031. This allows the target modulation structure 1031 to modulate the light from the side of the first pixel unit 102a closest to the second pixel unit 102b. Consequently, in the mixed light after the light emitted from the first pixel unit 102a and the light emitted from the second pixel unit 102b is mixed, the amount of light emitted from the first pixel unit 102a can be relatively small, thus avoiding color shift caused by a large difference in the amount of light emitted from the first pixel unit 102a and the second pixel unit 102b.

[0078] Furthermore, by setting the target modulation structure 1031 between the first pixel unit 102a and the second pixel unit 102b, crosstalk between the light emitted by the first pixel unit 102a and the light emitted by the second pixel unit 102b can be avoided, thus ensuring the display effect of the display module 100.

[0079] In summary, this application provides a display module including a substrate, multiple pixel units, and a light modulation layer. The multiple pixel units include adjacent first pixel units and second pixel units. A target modulation structure of the light modulation layer is located between the first and second pixel units, and the distance between the target modulation structure and the first pixel unit is less than the distance between the target modulation structure and the second pixel unit. Therefore, the target modulation structure can be used to modulate the light emitted from the side of the first pixel unit closest to the second pixel unit, thereby preventing color shift caused by the mixing of light emitted from the first and second pixel units and improving the display effect of the display module.

[0080] In this embodiment, the material of the target modulation structure 1031 may include at least one of a light-shielding material and a reflective material. The light-shielding material can be used to block and absorb light. The reflective material can be used to reflect and absorb light.

[0081] For example, the target modulation structure 1031 modulating light can mean that the target modulation structure 1031 can block, absorb, and reflect light. That is, the target modulation structure 1031 can modulate the light on the side of the first pixel unit 102a near the second pixel unit 102b using at least one of the modulation methods of blocking, absorbing, and reflecting.

[0082] Optionally, the plurality of pixel units 102 may include a red (R) pixel unit 102-R, a green (G) pixel unit 102-G, and a blue (B) pixel unit 102-B. The color of the light emitted by the red pixel unit 102-R may be red, the color of the light emitted by the green pixel unit 102-G may be green, and the color of the light emitted by the blue pixel unit 102-B may be blue.

[0083] Optionally, referring to FIG4, pixel unit 102 may include pixel circuit 1021 and light-emitting unit 1022. Pixel circuit 1021 may be connected to light-emitting unit 1022, and pixel circuit 1021 may be used to provide pixel driving signals to light-emitting unit 1022. Optionally, pixel circuit 1021 may include multiple thin-film transistors (TFTs) and at least one storage capacitor (Cst), and light-emitting unit 1022 may be an organic light-emitting diode (OLED) device. The pixel unit 102 illustrated in FIG1 may be the light-emitting unit 1022 within pixel unit 102.

[0084] In this embodiment of the application, referring to FIG4, the display module 100 includes a pixel circuit layer M and a light-emitting device layer N. The pixel circuit layer M may include pixel circuits 1021 of multiple pixel units 102, and the light-emitting device layer N may include light-emitting units 1022 of multiple pixel units 102.

[0085] Optionally, the pixel circuit layer M may include a buffer layer m1, a barrier layer m2, an active layer m3, a first gate insulator (GI1) m4, a first gate layer (gate1) m5, a second gate insulator (GI2) m6, a second gate layer (gate2) m7, an inter-level dielectric (ILD) m8, a first source-drain layer (SD1) m9, a passivation layer (PVX) m10, a first planarization layer (PLN1) m11, a second source-drain layer (SD2) m12, and a second planarization layer (PLN2) m13, stacked sequentially along a direction away from the substrate 101.

[0086] The active layer m3 can be a polysilicon layer (P-Si). The active layer m3 includes multiple active patterns of thin-film transistors, each including a source region and a drain region. The first gate layer m5 includes multiple first gate patterns m51 and multiple second gate patterns m52. The first gate pattern m51 can be the gate of a thin-film transistor, and the second gate pattern m52 can be the first electrode of a storage capacitor Cst. The second gate layer m7 includes multiple third gate patterns m71, each being the second electrode of a storage capacitor Cst.

[0087] The first source-drain layer m9 includes the source and drain of a thin-film transistor. The source is connected through vias in the interlayer dielectric layer m8, the second gate insulating layer m6, and the first gate insulating layer m4, as well as the source region of the active pattern. The drain is connected through vias in the interlayer dielectric layer m8, the second gate insulating layer m6, and the first gate insulating layer m4, as well as the drain region of the active pattern.

[0088] The second source-drain layer m12 includes a first connection pattern m121, which is connected to the drain of the thin-film transistor through vias in the first planarization layer m11 and the passivation layer m10. Furthermore, the first connection pattern m121 is also connected to the light-emitting unit 1022.

[0089] Referring to Figure 4, the light-emitting device layer N includes an anode layer (n1), a pixel definition layer (PDL) (n2), an emitting layer (EL) (n3), and a cathode layer (n4). The anode layer (n1), the emitting layer (n3), and the cathode layer (n4) can constitute multiple light-emitting units 1022.

[0090] The anode layer n1 includes multiple anode patterns n11, which can be connected to a second connecting pattern. The pixel defining layer n2 has multiple cutout areas, each of which can be used to expose at least a portion of an anode pattern n11.

[0091] The light-emitting layer n3 may include multiple light-emitting patterns n31, which can be connected through a cutout area and an anode pattern n11. The cathode layer n4 is connected to the light-emitting patterns n31 of multiple light-emitting units 1022.

[0092] Each light-emitting unit 1022 may include an anode pattern n11 located in the anode layer n1 (the anode pattern serves as the anode of the light-emitting pixel), a light-emitting pattern n31 located in the light-emitting layer n3 (the light-emitting pattern serves as the light-emitting layer of the light-emitting pixel), and a cathode layer n4. The cathode layer n4 of multiple light-emitting units 1022 may be a shared film layer, that is, the cathode layer n4 may serve as the cathode of each light-emitting unit 1022.

[0093] In this embodiment of the application, as can be seen from FIG4, the display module 100 further includes a thin-film encapsulation (TFE) 104 located on the side of the light-emitting device layer N away from the substrate 101. The encapsulation layer 104 may include a first film layer 1041, a second film layer 1042, and a third film layer 1043 sequentially stacked along the direction away from the substrate 101.

[0094] Optionally, the first film layer 1041 and the third film layer 1043 can be made of inorganic materials, primarily for blocking water and oxygen. The second film layer 1042 can be made of organic materials, primarily for stress relief and planarization. For example, the first film layer 1041 and the third film layer 1043 can be made of one or more inorganic oxides such as SiNx (silicon nitride), SiOx (silicon oxide), SiOxNy (silicon oxynitride), Al2O3 (alumina), and TiO2 (titanium oxide). The second film layer 1042 can be made of resin materials. The resin can be a thermoplastic resin or a thermosetting resin, where the thermoplastic resin can include acrylic (PMMA) resin and the thermosetting resin can include epoxy resin.

[0095] Optionally, the second film layer 1042 can be fabricated using inkjet printing (IJP), screen printing, or dispensing methods. The first film layer 1041 and the third film layer 1043 can be fabricated using chemical vapor deposition (CVD) or atomic layer deposition methods.

[0096] This application embodiment can determine the color of the light emitted by the first pixel unit 102a and the second pixel unit 102b based on the specific color shift of the display module 100. Currently, the main reasons for color shift problems in OLED devices are as follows: 1. Material aging; 2. Pixel arrangement; 3. Uneven current driving.

[0097] Material aging refers to the aging of organic light-emitting materials in OLED devices over time. The organic light-emitting material in the red pixel unit 102-R is red, the organic light-emitting material in the green pixel unit 102-G is green, and the organic light-emitting material in the blue pixel unit 102-B is blue. Typically, different colored organic light-emitting materials age at different rates, with the blue organic light-emitting material aging faster than the other two. This leads to a decrease in the brightness of the blue pixel unit 102-B, resulting in color deviations in the display module.

[0098] Pixel arrangement refers to the fact that different pixel arrangements may result in uneven color distribution and color deviation when displaying specific colors. For example, in the Pentile arrangement with RGBG pixel arrangement, the color deviation problem is particularly obvious under certain color or brightness conditions because the size and distribution of the pixel units 102 of different colors are different.

[0099] Uneven current drive refers to the fact that different current drives affect the brightness input of different colors. If the current drive is unstable, the brightness of a certain color may not meet expectations, resulting in color shift.

[0100] For example, if the display module 100 exhibits a bluish tint during display, this indicates that the light emitted by the green pixel unit 102-G in the display module 100 is greater than the light emitted by other pixel units 102. Therefore, a target modulation structure 1031 can be used to modulate (e.g., block, absorb, or reflect) the light emitted by the green pixel unit 102-G, reducing the amount of green light and thus improving the bluish tint problem of the display module 100. In this case, the green pixel unit 102-G can be a first pixel unit 102a, and the red pixel unit 102-R and the blue pixel unit 102-B can both be second pixel units 102b. That is, the orthographic projection of the target modulation structure 1031 on the substrate 101 can be located between the orthographic projection of the green pixel unit 102-G on the substrate 101 and the orthographic projection of the red pixel unit 102-R (or the blue pixel unit 102-B) on the substrate 101, and the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the green pixel unit 102-G on the substrate 101 is less than the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the red pixel unit 102-R (or the blue pixel unit 102-B) on the substrate 101.

[0101] Alternatively, if the display module 100 exhibits a reddish tint during display, this indicates that the amount of light emitted by the red pixel unit 102-R in the display module 100 is greater than the amount of light emitted by other pixel units 102. In this case, the target modulation structure 1031 can be used to modulate (e.g., block, absorb, or reflect) the light emitted by the red pixel unit 102-R, reducing the amount of red light and thus improving the reddish tint problem of the display module 100. In this scenario, the red pixel unit 102-R can be a first pixel unit 102a, and the green pixel unit 102-G and blue pixel unit 102-B can both be second pixel units 102b. That is, the orthographic projection of the target modulation structure 1031 on the substrate 101 can be located between the orthographic projection of the red pixel unit 102-R on the substrate 101 and the orthographic projection of the green pixel unit 102-G (or the blue pixel unit 102-B) on the substrate 101, and the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the red pixel unit 102-R on the substrate 101 is less than the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the green pixel unit 102-G (or the blue pixel unit 102-B) on the substrate 101.

[0102] Alternatively, if the display module 100 exhibits a bluish tint during display, this indicates that the amount of light emitted by the blue pixel unit 102-B in the display module 100 is greater than the amount of light emitted by other pixel units 102. Therefore, the target modulation structure 1031 can be used to modulate (e.g., block, absorb, or reflect) the light emitted by the blue pixel unit 102-B, reducing the amount of blue light and thus improving the bluish tint problem of the display module. In this case, the blue pixel unit 102-B can be a first pixel unit 102a, and the red pixel unit 102-R and the green pixel unit 102-G can both be second pixel units 102b. That is, the orthographic projection of the target modulation structure 1031 on the substrate 101 can be located between the orthographic projection of the blue pixel unit 102-B on the substrate 101 and the orthographic projection of the red pixel unit 102-R (or the green pixel unit 102-G) on the substrate 101, and the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the blue pixel unit 102-B on the substrate 101 is less than the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the red pixel unit 102-R (or the green pixel unit 102-G) on the substrate 101.

[0103] In this embodiment, referring to FIG5, the plurality of pixel units 102 include a plurality of third pixel units 102c, and the third pixel units 102c are also arranged adjacent to the first pixel unit 102a. In this embodiment, the first pixel unit 102a is a green pixel unit 102-G, the second pixel unit 102b is a red pixel unit 102-R, and the third pixel unit 102c is a blue pixel unit 102-B.

[0104] In the display module 100 shown in Figure 3, the target modulation structure 1031 is located between the green pixel unit 102-G and the red pixel unit 102-R, and the distance between the target modulation structure 1031 and the green pixel unit 102-G is smaller than the distance between the target modulation structure 1031 and the blue pixel unit 102-B.

[0105] Referring to Figure 5, the orthographic projection of the target modulation structure 1031 on the substrate 101 is located between the orthographic projections of the first pixel unit 102a and the third pixel unit 102c on the substrate 101. Furthermore, the distance d1 between the orthographic projections of the target modulation structure 1031 and the first pixel unit 102a on the substrate 101 is less than the distance d3 between the orthographic projections of the target modulation structure 1031 and the third pixel unit 102c on the substrate 101.

[0106] Since the distance d1 between the target modulation structure 1031 and the first pixel unit 102a in the light modulation layer 103 is small, and the distance d2 between the target modulation structure 1031 and the third pixel unit 102c is large, the target modulation structure 1031 can be used to modulate the light emitted by the first pixel unit 102a without significantly affecting the light emitted by the third pixel unit 102c.

[0107] Furthermore, since the target modulation structure 1031 is located between the first pixel unit 102a and the third pixel unit 102c, a portion of the light emitted from the first pixel unit 102a that is directed towards the third pixel unit 102c can illuminate the target modulation structure 1031. This allows the target modulation structure 1031 to modulate the light from the side of the first pixel unit 102a closest to the third pixel unit 102c. Consequently, in the mixed light produced by the mixing of the light emitted from the first pixel unit 102a and the third pixel unit 102c, the amount of light emitted from the first pixel unit 102a can be relatively small, thus avoiding color shift caused by a large difference in the amount of light emitted from the first pixel unit 102a and the third pixel unit 102c.

[0108] In this embodiment, because the anode layer n1 in the light-emitting device layer N has more film layers on the side closest to the substrate 101, and there are more connecting vias between the film layers, the flatness of the surface used to form the anode layer n is poor. For example, in FIG6, the distance h1 between the first side n11a of the anode pattern n11 and the substrate 101 is smaller than the distance h2 between the second side n11b of the anode pattern n11 and the substrate 101. In this case, referring to FIG6, at the same viewing angle, the light emission of the light-emitting unit 1022 on the first side n11a of the anode pattern n11 is higher than the light emission of the light-emitting unit 1022 on the second side n11b of the anode pattern n11. As a result, the brightness attenuation uniformity of different sides of the light-emitting unit 1022 is poor, which in turn leads to poor color shift symmetry of the light-emitting unit 1022.

[0109] Furthermore, in this embodiment of the application, the target modulation structure 1031 in the light modulation layer 103 can be designed based on the non-flatness of the anode pattern n11 in the light-emitting unit 1022 of the pixel unit 102. For example, the target modulation structure 1031 can be disposed on the first side n11a, which is closer to the anode pattern n11 and the substrate 101. By blocking the light emitted from the first side n11a of the light-emitting unit 1022 near the anode pattern n11, the light emission from the first side n11a is reduced, the brightness attenuation consistency of different sides of the light-emitting unit 1022 is optimized, and the color shift symmetry of the light-emitting unit 1022 is improved.

[0110] In this embodiment of the application, referring to FIG7, the orthographic projection of the target modulation structure 1031 on the substrate 101 surrounds the orthographic projection of the first pixel unit 102a on the substrate 101. That is, the target modulation structure 1031 surrounding the first pixel unit 102a can be a ring structure, which can modulate the light of the first pixel unit 102a from multiple angles and reduce the light output of the first pixel unit 102a.

[0111] Optionally, the first pixel unit 102a can be arranged adjacent to the second pixel unit 102b, or adjacent to other pixel units 102. The distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101 is smaller than the distance between the orthographic projection of the target modulation structure 1031 on the substrate 101 and the orthographic projection of any pixel unit 102 adjacent to the first pixel unit 102a on the substrate 101.

[0112] In this embodiment of the application, referring to FIG4, the display module 100 includes a touch functional layer 105 located on the side of the plurality of pixel units 102 away from the substrate 101. The touch functional layer 105 includes a touch buffer layer 1051, a first touch conductive layer 1052, a touch insulating layer 1053, a second touch conductive layer 1054, and a touch protective layer 1055 stacked along the direction away from the substrate 101.

[0113] Optionally, the first touch conductive layer 1052 can be referred to as the first touch metal (TMA) layer. The touch insulating layer 1053 can be referred to as the dielectric layer (TLD) of the touch screen panel (TSP). The second touch conductive layer 1054 can be referred to as the second touch metal (TMB) layer.

[0114] Optionally, if the display module includes a touch function layer 105, the display module can be a touch display module using flexible multi-layer on cell (FMLOC) technology.

[0115] Optionally, the touch buffer layer 1051 can be made of SiN (silicon nitride). The first touch conductive layer 1052 and the second touch conductive layer 1054 can both be made of a triple-layer structure of Ti (titanium), Al (aluminum), and Ti (titanium), and the materials of the first touch conductive layer 1052 and the second touch conductive layer 1054 can be denoted as Ti / Al / Ti. The touch insulating layer 1053 can be made of SiN (silicon nitride).

[0116] Optionally, the first touch conductive layer 1052 and the second touch conductive layer 1054 constitute mutually insulated first touch electrodes s1 and s2. Both the first touch electrodes s1 and s2 have a mesh-like structure. Referring to FIG4, the first touch conductive layer 1052 includes a bridging electrode s12 of the first touch electrode s1, and the second touch conductive layer 1054 includes a main electrode s11 of the first touch electrode s1 and the second touch electrode s2. The bridging electrode s12 and the main electrode s11 of the first touch electrode s1 are electrically connected through vias in the touch insulating layer 1053. The first touch electrodes s1 and s2 are mutually insulated.

[0117] Optionally, one of the first touch electrode s1 and the second touch electrode s2 can be a transmitting (TX) electrode, and the other touch electrode can be a sensing (RX) electrode.

[0118] Referring to Figure 8, the mesh structure B of the touch electrode includes multiple meshes, and the orthographic projection of each mesh on the substrate 101 surrounds the orthographic projection of a pixel unit 102 on the substrate 101. Since the material of the touch conductive layer can usually be a metallic material, the meshes in the mesh structure formed by this touch conductive layer can block, absorb, and reflect light.

[0119] For example, the orthographic projection of the first grid B1 in a plurality of grids onto the substrate 101 surrounds the orthographic projection of the first pixel unit 102a onto the substrate 101, and at least a portion of the first grid B1 may be the target modulation structure 1031. In this embodiment, for ease of annotation, the first grid B1 is represented by an extension line.

[0120] In this embodiment of the application, referring to FIG8, the first grid B1 includes a first sub-part B11 and a second sub-part B12. The distance e1 between the first sub-part B11 and the first pixel unit 102a is less than or equal to the distance e2 between the second sub-part B12 and the first pixel unit 102a. The target modulation structure 1031 includes at least the first sub-part B11.

[0121] Optionally, referring to FIG8, if the distance e1 between the first sub-part B11 and the first pixel unit 102a is less than the distance e2 between the second sub-part B12 and the first pixel unit 102a, the target modulation structure 1031 may include the first sub-part B11. Referring to FIG9, if the distance e1 between the first sub-part B11 and the first pixel unit 102a is equal to the distance e2 between the second sub-part B12 and the first pixel unit 102a, the target modulation structure 1031 may include the first sub-part B11 and the second sub-part B12.

[0122] Optionally, the scheme in which the distance between the first sub-part B11 and the first pixel unit 102a is less than the distance between the second sub-part B12 and the first pixel unit 102a may include Scheme 1, Scheme 2 and Scheme 3.

[0123] Option 1 (Offset), as shown in Figure 8, involves offsetting the mesh structure as a whole along the target direction X. The target direction X can be the direction from the first sub-part B11 to the second sub-part B12. This can be achieved during fabrication by adjusting the position of the mask used to fabricate the mesh structure. The target direction X can also be the direction from the side of the first pixel unit with more light to the side with less light.

[0124] Option 2 (recession), as shown in Figure 10, involves retracting the first sub-part B11 of the first grid B1 in the mesh structure towards the first pixel unit 102a. This can be achieved by designing a new mask during fabrication.

[0125] Option 3 (widening), as shown in Figure 11, involves a first sub-part B11 with a projection width f1 greater than the second sub-part B12 with a projection width f2 greater than the first sub-part B11 with a projection width f3 greater than the projection widths f3 of the other meshes with projection widths f3 greater than the first sub-part B11 with projection width f2 greater than the projection widths f3 of the other meshes with projection widths f3 greater than the first sub-part B11 with projection width f3 greater than the first sub-part B12 with projection width f2 greater than the projection widths f3 of the other meshes with projection widths f3 greater than the first sub-part B11 with projection width f2 greater than the first sub-part B12 with projection width f3 greater than the first sub-part B12 with projection width f3 greater than the first sub-part B12 with projection width f2 ...3 greater than the first sub-part B12 with projection width f2 greater than the first sub-part B12 with projection width f3 greater than

[0126] Optionally, the scheme in which the distance e1 between the first sub-part B11 and the first pixel unit 102a is equal to the distance e2 between the second sub-part B12 and the first pixel unit 102a may include the following schemes four and five.

[0127] Option 4 (shrinkage), as shown in Figure 9, involves shrinking the first sub-parts B11 and B12 of the first grid B1 in the mesh structure towards the first pixel unit 102a. This can be achieved by designing a new mask during fabrication.

[0128] Option 5 (widening), as shown in Figure 12, has a width f1 of the orthographic projection of the first sub-part B11 onto the substrate 101 equal to the width f2 of the orthographic projection of the second sub-part B12 onto the substrate 101, and both are greater than the width f3 of the orthographic projections of the other meshes onto the substrate 101. This can be achieved by designing a new mask during fabrication.

[0129] As can be seen from Schemes 1 to 5 above, the offset scheme is applicable when the first sub-part B11 in the first grid B1 is the target modulation structure 1031. The shrinking and widening schemes are applicable when the first sub-part B11 in the first grid B1 is the target modulation structure 1031, and also applicable when both the first sub-part B11 and the second sub-part B12 in the first grid B1 are the target modulation structure 1031. Furthermore, the shrinking and widening schemes can be designed to shrink or widen part or all of the first grid B1 according to the actual product requirements, offering greater flexibility.

[0130] In this embodiment of the application, referring to FIG13, the orthographic projection of the second grid B2 in the plurality of grids on the substrate 101 surrounds the orthographic projection of the second pixel unit 102b on the substrate 101. The portion of the first grid B1 near the second grid B2 and the portion of the second grid B2 near the first grid B1 constitute a first common portion Ba of the first grid B1 and the second grid B2, and the target modulation structure 1031 may include at least a portion of the first common portion Ba.

[0131] Optionally, referring to Figure 13, the distance e1 between the first shared portion Ba and the first pixel unit 102a can be less than the distance g1 between the first shared portion Ba and the second pixel unit 102b. For example, when using an offset scheme (or a shrinking scheme), the width of each grid in the grid structure remains unchanged, and the first shared portion Ba, shared by the first grid B1 and the second grid B1, is offset (or shrunk) towards the first pixel unit 102a. In this case, the difference between the distance g1 between the first shared portion Ba and the second pixel unit 102b and the distance e1 between the first shared portion Ba and the first pixel unit 102a can be approximately twice the offset (or shrinking) amount of the first shared portion Ba. Alternatively, referring to Figure 14, the first shared portion Ba, shared by the first grid B1 and the second grid B2, can be widened towards the first pixel unit 102a. In this case, the distance g1 between the first common portion Ba and the second pixel unit 102b remains unchanged, the distance e1 between the first common portion Ba and the first pixel unit 102a decreases, and the amount of decrease in the distance between the first common portion Ba and the first pixel unit 102a can be equal to the amount of widening of the first common portion Ba in the direction closer to the first pixel unit 102a.

[0132] Optionally, the indentation amount can range from 0.7 μm to 1.4 μm. When the indentation amount is 0.7 μm, the difference between the distance g1 between the first common portion Ba and the second pixel unit 102b and the distance e1 between the first common portion Ba and the first pixel unit 102a can be approximately 1.4 μm. For example, if both distance g1 and distance e1 are 7.6 μm and the indentation amount is 0.7 μm, distance g1 can vary to 8.3 μm, and distance e1 can vary to 6.9 μm.

[0133] With an indentation of 1.4 μm, the difference between the distance g1 between the first common portion Ba and the second pixel unit 102b and the distance e1 between the first common portion Ba and the first pixel unit 102a can be approximately 2.8 μm. For example, if both distance g1 and distance e1 are 7.6 μm and the indentation is 1.4 μm, distance g1 can change to 9.0 μm and distance e1 can change to 6.2 μm.

[0134] In this embodiment, referring to FIG13, the first grid B1 includes a first sub-part B11 and a second sub-part B12, and the second grid B1 includes a third sub-part B21 and a fourth sub-part B22. The distance e1 between the first sub-part B11 and the first pixel unit 102a is less than the distance e2 between the second sub-part B12 and the first pixel unit 102a. The first sub-part B11 is closer to the second pixel unit 102b relative to the second sub-part B12. The distance g2 between the third sub-part B21 and the second pixel unit 102b is less than the distance g1 between the fourth sub-part B22 and the second pixel unit 102b. The fourth sub-part B22 is closer to the first pixel unit 102a relative to the third sub-part B21. The first common portion Ba includes at least a portion of the first sub-part B11 and at least a portion of the fourth sub-part B22.

[0135] Referring to Figures 13 and 14, the first sub-parts B11 and B12, divided by the first grid B1, can be approximately L-shaped, as can the third sub-parts B21 and B22, divided by the second grid B2. The first sub-part B11 includes a portion shared with the fourth sub-part B22, as well as a portion not shared with it. Similarly, the fourth sub-part B22 includes a portion shared with the first sub-part B11, as well as a portion not shared with it. Therefore, the first shared portion Ba can include the portion shared by the first sub-part B11 and the fourth sub-part B22, or it can be understood as the intersection of the first sub-part B11 and the fourth sub-part B22.

[0136] In this embodiment of the application, the division and position of the first grid and the second grid in Figures 13 and 14 are used as examples. If the relative position of the first grid and the second grid changes, the first common part Ba can also be the intersection of the second sub-part B12 and the third sub-part B21, or the intersection of the first sub-part B11 and the third sub-part B21, or the intersection of the second sub-part B12 and the fourth sub-part B22.

[0137] Optionally, for ease of description, the offset scheme, shrinkage scheme, and widening scheme in the embodiments of this application are based on the premise that the grid portion located between any two adjacent pixel units 102 is located in the middle of the interval between adjacent pixel units 102. Alternatively, it can be understood that the distance between the grid portion and two adjacent pixel units 102 is equal.

[0138] For example, the first common portion Ba being shifted closer to the first pixel unit 102a can mean that the first common portion Ba was originally located in the middle of the gap between the first pixel unit 102a and the second pixel unit 102b, and the first common portion Ba is shifted from the middle by the shift, so that the first common portion Ba is closer to the first pixel unit 102a.

[0139] The first common portion Ba shrinking inward toward the first pixel unit 102a can mean that the first common portion Ba was originally located in the middle of the gap between the first pixel unit 102a and the second pixel unit 102b. By shrinking inward, the first common portion Ba shrinks inward from the middle toward the first pixel unit 102a, so that the first common portion Ba is closer to the first pixel unit 102a.

[0140] The widening of the first common portion Ba toward the first pixel unit 102a can mean that the first common portion Ba was originally located in the middle of the gap between the first pixel unit 102a and the second pixel unit 102b. By widening it, the first common portion Ba is widened toward the first pixel unit 102a, while the distance of the first common portion toward the second pixel unit 102b remains unchanged, so that the first common portion Ba is closer to the first pixel unit 102a.

[0141] In the offset scheme, due to the overall offset of the grid structure B, when the first sub-part B11 shifts closer to the first pixel unit 102a, the fourth sub-part B22, shared with the first sub-part B11, also shifts closer to the first pixel unit 102a; that is, the fourth sub-part B22 shifts away from the second pixel unit 102b. Simultaneously, the second sub-part B12 shifts away from the first pixel unit 102a, and the third sub-part B21 shifts closer to the second pixel unit 102b. This reduces the distance between the first sub-part B11 and the first pixel unit 102a, and increases the distance between the second sub-part B12 and the first pixel unit 102a; that is, the distance between the first sub-part B11 and the first pixel unit 102a is less than the distance between the second sub-part B12 and the first pixel unit 102a. Simultaneously, this reduces the distance between the third sub-part B21 and the first pixel unit 102a, while increasing the distance between the fourth sub-part B22 and the second pixel unit 102b. Specifically, the distance between the third sub-part B21 and the second pixel unit 102b is less than the distance between the fourth sub-part B22 and the second pixel unit 102b. In other words, besides the first sub-part B11 of the first grid B1 surrounding the first pixel unit 102a serving as the target modulation structure 1031 for modulating the light from the first pixel unit 102a, the third sub-part B21 of the second grid B2 surrounding the second pixel unit 102b can also serve as the target modulation structure 1031 for modulating the light from the second pixel unit 102b.

[0142] In the shrinking scheme, the first sub-part B11 of the first grid B1 is shrunk inward toward the first pixel unit 102a. Therefore, the fourth sub-part B22, which is shared with the first sub-part B11, also moves inward toward the first pixel unit 102a. Alternatively, it can be understood that the fourth sub-part B22, which is shared with the first sub-part B11, moves away from the second pixel unit 102b. Furthermore, the distance between the second sub-part B12 and the first pixel unit 102a, and the distance between the third sub-part B21 and the second pixel unit 102b, can remain unchanged. Furthermore, when the distance between the first sub-part B11 and the first pixel unit 102a decreases, and the distance between the fourth sub-part B22 and the second pixel unit 102b increases, the distance between the first sub-part B11 and the first pixel unit 102a is less than the distance between the second sub-part B12 and the second pixel unit 102b, and the distance between the third sub-part B21 and the second pixel unit 102b is less than the distance between the fourth sub-part B22 and the second pixel unit 102b.

[0143] In the widening scheme, the first sub-part B11 of the first grid B1 is widened towards the first pixel unit 102a. Therefore, the fourth sub-part B22, which is shared with the first sub-part B11, is also widened towards the first pixel unit 102a. Furthermore, the distances between the second sub-part B12 and the first pixel unit 102a, the distance between the third sub-part B21 and the second pixel unit 102b, and the distance between the fourth sub-part B22 and the second pixel unit 102b can remain unchanged. When the distance between the first sub-part B11 and the first pixel unit 102a decreases, and the distances between the fourth sub-part B22 and the second pixel unit 102b, the distance between the second sub-part B12 and the first pixel unit 102a, and the distance between the third sub-part B21 and the second pixel unit 102b can all remain unchanged, the distance between the first sub-part B11 and the first pixel unit 102a is smaller than the distance between the second sub-part B12 and the second pixel unit 102b. The distance between the third sub-part B21 and the second pixel unit 102b may or may not be equal to the distance between the fourth sub-part B22 and the second pixel unit 102b.

[0144] In this embodiment of the application, referring to FIG15, the plurality of pixel units 102 include a plurality of target pixel units 102M disposed adjacent to the second pixel unit 102b. In the pixel arrangement shown in FIG15, the plurality of target pixel units 102M are all first pixel units 102a. In this case, the second grid B2 corresponding to the second pixel unit 102b and the first grid B1 corresponding to each first pixel unit 102a both have a first common portion Ba. The distance e1 or e2 between the orthographic projection of any first common portion Ba on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101 is less than the distance g1 or g2 between the orthographic projection of the first common portion Ba on the substrate 101 and the orthographic projection of the second pixel unit 102b on the substrate 101.

[0145] That is, in each of the plurality of first pixel units 102a arranged adjacent to the second pixel unit 102b, the first common portion Ba between each first pixel unit 102a and the second pixel unit 102b is biased towards the first pixel unit 102a. For example, it is narrowed or widened in the direction closer to the first pixel unit 102a.

[0146] For the offset scheme, in the plurality of first pixel units 102a arranged adjacent to the second pixel unit 102b, a portion of the first common portion Ba between the first pixel unit 102a and the second pixel unit 102b is biased toward the first pixel unit 102a, and another portion of the first common portion Ba between the first pixel unit 102a and the second pixel unit 102b is biased toward the second pixel unit 102b.

[0147] In this embodiment, referring to FIG13, the orthographic projection of the third grid B3 in the plurality of grids on the substrate 101 surrounds the orthographic projection of the third pixel unit 102c on the substrate 101. The portion of the first grid B1 near the third grid B3 and the portion of the third grid B3 near the first grid constitute the second common portion Bb. The target modulation structure 1031 includes at least a portion of the second common portion Bb. The distance between the orthographic projection of the second common portion Bb on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101 is less than the distance between the orthographic projection of the second common portion Bb on the substrate 101 and the orthographic projection of the third pixel unit 102c on the substrate 101.

[0148] Optionally, the design of the second common portion Bb can be similar to the design of the first common portion Ba. For example, the grid structure can be offset to bring the second common portion Bb closer to the first pixel unit 102a. Alternatively, the second common portion Bb can be narrowed or widened in the direction closer to the first pixel unit 102a.

[0149] Referring to Figures 8 and 9, the pixel units adjacent to the first pixel unit 102a include two second pixel units 102b and two third pixel units 102c. The first shared portion Ba in the above embodiment may include portions shared by the first grid B1 surrounding the first pixel unit 102a and the two second grids B2 surrounding the two second pixel units 102b. Similarly, the second shared portion Bb in the above embodiment may include portions shared by the first grid B1 surrounding the first pixel unit 102a and the two third grids B3 surrounding the two third pixel units 102c.

[0150] In this embodiment, the entire first grid B1 surrounding the first pixel unit 102a can serve as the target modulation structure 1031 for modulating the light from the first pixel unit 102a. The distance between any position of the first grid B1 and the first pixel unit 102a is less than the distance between any position of the grid surrounding any pixel unit 102 adjacent to the first pixel unit 102a and that pixel unit 102. In this case, any position of the first grid B1 can be either narrowed or widened towards the first pixel unit 102a.

[0151] Referring to Figure 16, the first grid B1 may include a first grid portion B1-1. The first grid portion B1-1 may be located in the second touch conductive layer 1054, and the first grid portion B1-1 is connected to a portion of the other grids located in the second touch conductive layer 1054. The orthographic projection of the first grid portion B1-1 on the substrate 101 surrounds the orthographic projection of the first pixel unit 102a on the substrate 101.

[0152] Optionally, the first grid portion B1-1 can be a grid formed by the main electrodes s11 of the first touch electrode s1 surrounding the first pixel unit 102a, or it can be a grid formed by the second touch electrode s2 surrounding the first pixel unit 102a. When the first grid portion B1-1 is a grid formed by the main electrodes s11 of the first touch electrode s1 surrounding the first pixel unit 102a, the first grid portion B1-1 can be connected to multiple grids formed by the main electrodes s11 of the first touch electrode s1. When the first grid portion B1-1 is a grid formed by the second touch electrode s2 surrounding the first pixel unit 102a, the first grid portion B1-1 can be connected to multiple grids formed by the second touch electrode s2.

[0153] In the embodiments of this application, when the first grid B1 includes a first grid portion B1-1, the first grid portion B1-1 can be designed to offset, shrink or widen, so that at least a portion of the first grid portion B1-1 can be the target modulation structure 1031.

[0154] Referring to Figure 17, the first grid B1 further includes a second grid portion B1-2. The second grid portion B1-2 is located in the first touch conductive layer 1052, and is not connected to the other grids located in the first touch conductive layer 1052. The other grids in the first touch conductive layer 1052 can be formed by the bridging electrode s12 of the first touch electrode s1. The fact that the second grid portion B1-2 is not connected to the other grids can mean that the second grid portion B1-2 is a dummy grid portion or a floating grid portion, not connected to any electrical signal. The second grid portion B1-2 is represented by a bold line in Figure 17.

[0155] Optionally, the orthographic projection of the second grid portion B1-2 on the substrate 101 and the orthographic projection of the first grid portion B1-1 on the substrate 101 at least partially overlap, and the orthographic projection of the second grid portion B1-2 on the substrate 101 surrounds at least a portion of the orthographic projection of the first pixel unit 102a on the substrate 101.

[0156] When the first grid B1 includes a first grid portion B1-1 and a second grid portion B1-2, the second grid portion B1-2 and the first grid portion B1-1 that overlaps with the second grid portion B1-2 can be parts of the first grid B1 as the target modulation structure 1031. For example, in Figure 17, the first part B1-11 and the second part B1-12 of the first grid portion B1-1 both overlap with the second grid portion B1-2, while the third part B1-13 and the fourth part B1-14 of the first grid portion B1-1 do not overlap with the second grid portion B1-2. The first part B1-11 and the second part B1-12 of the first grid portion B1-1, as well as the second grid portion B1-2, can be the target modulation structure 1031. That is, the union projection of the first part B1-11 and the second part B1-12 of the first grid part B1-1 on the substrate 101 and the second grid part B1-2 on the substrate 101 can be the orthogonal projection of the target modulation structure 1031 on the substrate 101.

[0157] Optionally, the distance v1 between the orthographic projection of the second grid portion B1-2 on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101 is less than the distance v2 between the orthographic projection of the first grid portion B1-1 on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101.

[0158] For example, the width and position of the orthographic projection of the first grid portion B1-1 on the substrate 101 can remain unchanged. The orthographic projection of the first grid portion B1-1 on the substrate 101 can be located in the middle of the gap between the orthographic projection of the first pixel unit 102a on the substrate 101 and the orthographic projection of the second pixel unit 102b on the substrate 101. The orthographic projection of the second grid portion B1-2 on the substrate 101 includes a portion that overlaps with the orthographic projection of the first grid portion B1-1 on the substrate 101, and a portion that does not overlap with the orthographic projection of the first grid portion B1-1 on the substrate 101. The orthographic projection of the portion of the second grid portion B1-2 that does not overlap with the first grid portion B1-1 on the substrate 101 can be located on the side of the orthographic projection of the first grid portion B1-1 on the substrate 101 closer to the first pixel unit 102a.

[0159] The width k1 of the orthographic projection of the second grid portion B1-2 onto the substrate 101 can be greater than the width k2 of the orthographic projection of the first grid portion B1-1 onto the substrate 101. For example, in Figure 17, the edge of the orthographic projection of the second grid portion B1-2 onto the substrate 101 away from the first pixel unit 102a overlaps with the edge of the orthographic projection of the first grid portion B1-1 onto the substrate 101 away from the first pixel unit 102a, and the edge of the orthographic projection of the second grid portion B1-2 onto the substrate 101 near the first pixel unit 102a is closer to the first pixel unit 102a than the edge of the orthographic projection of the first grid portion B1-1 onto the substrate 101 near the first pixel unit 102a.

[0160] Alternatively, referring to Figure 18, the distance v1 between the orthographic projection of the second grid portion B1-2 on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101 can also be equal to the distance v2 between the orthographic projection of the first grid portion B1-1 on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101.

[0161] For example, the distance between the first grid portion B1-1 and the first pixel unit 102a can be reduced by offsetting, shrinking, or widening. The orthographic projection of the second grid portion B1-2 on the substrate 101 near the first pixel unit 102a can overlap with the orthographic projection of the first grid portion B1-1 on the substrate 101 near the first pixel unit 102a. In this case, the target modulation structure 1031 includes a two-layer structure, which can further ensure the modulation of the light from the first pixel unit 102a.

[0162] The width k1 of the orthographic projection of the second grid portion B1-2 onto the substrate 101 can be equal to the width k2 of the orthographic projection of the first grid portion B1-1 onto the substrate 101. For example, in Figure 18, the edge of the orthographic projection of the second grid portion B1-2 onto the substrate 101 away from the first pixel unit 102a overlaps with the edge of the orthographic projection of the first grid portion B1-1 onto the substrate 101 away from the first pixel unit 102a, and the edge of the orthographic projection of the second grid portion B1-2 onto the substrate 101 near the first pixel unit 102a overlaps with the edge of the first grid portion B1-1 onto the substrate 101 near the first pixel unit 102a.

[0163] In this embodiment, referring to FIG19, the touch insulating layer 1053 includes a recess P, the orthographic projection of which on the substrate 101 lies between the orthographic projection of the first grid B1 on the substrate 101 and the orthographic projection of the first pixel unit 102a on the substrate 101. The orthographic projection of the recess P on the substrate 101 surrounds at least a portion of the orthographic projection of the first pixel unit 102a on the substrate 101, and the target modulation structure 1031 includes the recess P. For example, in FIG19, the orthographic projection of the recess P on the substrate 101 completely surrounds the orthographic projection of the first pixel unit 102a on the substrate 101.

[0164] In order for the recess P to function as the modulated light of the target modulation structure 1031, the refractive index of the touch protective layer 1055 can be made smaller than that of the touch insulating layer 1053, and the size of the side of the recess P closer to the substrate 101 can be smaller than the size of the side of the recess P farther from the substrate 101. For example, the orthographic projection of the recess P on the reference plane in Figure 20 can be an inverted trapezoid, and the reference plane can be perpendicular to the surface of the substrate 101 and perpendicular to the extension direction of the recess P.

[0165] Optionally, the refractive index of the touch protective layer 1055 can be in the range of 1.3 to 1.6, such as 1.46. The refractive index of the touch insulating layer 1053 can be in the range of 1.65 to 2, such as 1.85.

[0166] Referring to Figure 20, the recess P may include a first sidewall P1 and a second sidewall P2. The orthographic projection of the first sidewall P1 onto the substrate 101 is closer to the orthographic projection of the first pixel unit 102a onto the substrate 101 than the orthographic projection of the second sidewall P2 onto the substrate 101. Light emitted from the first pixel unit 102a can be incident from the touch insulating layer 1053 onto the first sidewall P1, and after refraction on the first sidewall P1, it exits from the touch protective layer 1055. That is, the first sidewall P1 can be used to change the direction of the light emitted from the first pixel unit 102a. Furthermore, light emitted from the first pixel unit 102a can be incident from the touch protective layer 1055 onto the second sidewall P2, and after reflection on the second sidewall P2, it exits from the touch protective layer 1055 (the material of the touch insulating layer 1053 itself can have the characteristic of reflecting light). That is, the second sidewall P2 can also be used to change the direction of the light emitted from the first pixel unit 102a. This reduces the large viewpoint angle deviation of the light emitted by the first pixel unit 102a.

[0167] Optionally, the recess P may also include a bottom surface P3. The angle between the first sidewall P1 and the bottom surface P3, and the angle between the second sidewall P2 and the bottom surface P3, can range from 105° to 120°. The angle between the first sidewall P1 and the bottom surface P3 may be the same as or different from the angle between the second sidewall P2 and the bottom surface P3; this embodiment does not limit this.

[0168] Referring to Figures 21 and 22, the second touch conductive layer 1054 may further include a dummy portion 10541, which at least covers the second sidewall P2. Covering the second sidewall P2 with the dummy portion 10541 ensures effective light reflection. The dummy portion 10541 may refer to a portion that does not receive any electrical signals and is insulated from the first grid B1.

[0169] Optionally, referring to Figure 22, in addition to covering the second sidewall P2, the dummy part can also be located on the side of the touch insulating layer 1053 away from the substrate 101 to ensure the modulation effect of light.

[0170] Optionally, the distance between the orthographic projection of the recess P on the substrate 101 and the cutout area of ​​the pixel defining layer n2 is greater than or equal to 4 μm (micrometers). The width of the orthographic projection of the recess P on the substrate 101 can range from 3 μm to 4 μm, for example, 3.5 μm. The distance between the orthographic projection of the recess P on the substrate 101 and the orthographic projection of the first mesh B1 on the substrate 101 is greater than 0 μm. The width of the orthographic projection of the dummy part 10541 on the substrate 101 can range from 2 μm to 4 μm, for example, 3 μm.

[0171] In the embodiments of this application, the target modulation structure 1031 can be obtained by offsetting, shrinking, or widening the first grid. Alternatively, the target modulation structure 1031 can also be a pit in the touch insulating layer. Or, the target modulation structure 1031 can also be formed by both pits and dummy parts.

[0172] In this embodiment of the application, as can be seen from Figures 8 to 19 and Figure 21 above, adjacent grids in the mesh structure can have shared portions. For ease of description, these shared portions can be the shared portions of the first grid around the first pixel unit and the second grid around the second pixel unit, or the shared portions of the first grid around the first pixel unit and the third grid around the third pixel unit.

[0173] Of course, when the pixel arrangement is other, the second pixel unit and the third pixel unit may also be arranged adjacent to each other. In this case, the second grid around the second pixel unit and the third grid around the third pixel unit may also have a shared portion. The orthographic projection of the shared portion of the second grid and the third grid onto the substrate 101 may be located in the middle of the interval between the orthographic projection of the second pixel unit onto the substrate 101 and the orthographic projection of the third pixel unit onto the substrate 101. Of course, the shared portion of the second grid and the third grid may also be set according to the specific color shift of the second pixel unit and the third pixel unit. This application embodiment does not limit this.

[0174] In summary, this application provides a display module including a substrate, multiple pixel units, and a light modulation layer. The multiple pixel units include adjacent first pixel units and second pixel units. A target modulation structure of the light modulation layer is located between the first and second pixel units, and the distance between the target modulation structure and the first pixel unit is less than the distance between the target modulation structure and the second pixel unit. Therefore, the target modulation structure can be used to modulate the light emitted from the side of the first pixel unit closest to the second pixel unit, thereby preventing color shift caused by the mixing of light emitted from the first and second pixel units and improving the display effect of the display module.

Furthermore, various modifications and changes may be made within the scope of the appended claims.

[0181] Furthermore, in describing representative embodiments, the specification may have presented methods and / or processes as a specific sequence of steps. However, the method or process should not be limited to the specific order of steps described herein, to the extent that it does not depend on such a specific order.

Moreover, the claims concerning the method and / or process should not be limited to the steps performed in the written order, and those skilled in the art will readily understand that these orders can be varied and still remain within the spirit and scope of the embodiments of this application.

[0182] In the accompanying drawings, the size of one or more constituent elements, the thickness of layers, or areas are sometimes exaggerated for clarity. Furthermore, the drawings schematically illustrate ideal examples, and this application is not limited to the shapes or numerical values ​​shown in the drawings.

[0183] The ordinal numbers "first," "second," and "third" used in this specification are for the purpose of avoiding confusion among the constituent elements, not for limiting the quantity. The term "multiple" in this application refers to two or more quantities.

[0184] The thickness range of the film layer in this specification is A to B, which means that the thickness is between A and B, including the two endpoints of A and B.

[0185] In this specification, for convenience, terms such as "middle," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships in conjunction with the accompanying drawings. This is solely for the purpose of facilitating the description and simplification, and does not imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. The positional relationships of the constituent elements may be appropriately varied depending on the orientation of the described constituent elements. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0186] In this specification, unless otherwise expressly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection, an indirect connection via an intermediate component, or a connection within two components. Those skilled in the art will understand the meaning of the above terms in this application according to the specific circumstances.

[0187] In this specification, a transistor is a device that includes at least three terminals: a gate electrode, a drain electrode (drain terminal, drain region, or drain), and a source electrode (source terminal, source region, or source). A transistor has a channel region between the drain and source electrodes, and current can flow through the drain electrode, the channel region, and the source electrode. Note that in this specification, the channel region refers to the region through which current primarily flows.

[0188] In this specification, the first terminal of a transistor can be the drain electrode and the second terminal of a transistor can be the source electrode, or vice versa. In cases where transistors with opposite polarities are used or where the current direction changes during circuit operation, the functions of the "source electrode" and "drain electrode" are sometimes interchanged. Therefore, in this specification, the "source electrode" and "drain electrode" can be interchanged, and the "source terminal" and "drain terminal" can be interchanged.

[0189] In this specification, "connection" includes the situation where constituent elements are connected together by a component that has a certain electrical function. There are no particular limitations on the "component that has a certain electrical function," as long as it enables the transmission of electrical signals between the connected constituent elements. Examples of "components that have a certain electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other components with various functions.

[0190] In this specification, the terms "film" and "layer" may be interchanged. For example, "conductive layer" may sometimes be replaced with "conductive film." Similarly, "insulating film" may sometimes be replaced with "insulating layer."

[0191] In this application, "thickness" and "height" refer to the vertical distance between the surface of the film layer away from the substrate and the surface of the film layer closer to the substrate.

[0192] In this specification, triangles, rectangles, trapezoids, pentagons, or hexagons are not strictly defined; they can be approximate triangles, rectangles, trapezoids, pentagons, or hexagons. Small deformations due to tolerances are possible, as are chamfers, curved edges, and other variations.

[0193] In this application, "about" means a value that is not strictly limited and allows for process and measurement errors.

[0194] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
