[0054] Figure 1 FIG. 4 is a cross-sectional diagram of an electronic device according to an embodiment of the present disclosure. Figure 2A FIG. 1 is a partially enlarged cross-sectional schematic diagram of a conventional pixel according to an embodiment of the present disclosure. Figure 2B This is a partially enlarged cross-sectional schematic diagram of a functional pixel of an embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 1 , Figure 2A and Figure 2B Some components are omitted from the illustration. Figure 1 , the electronic device 1 of this embodiment includes a display panel 10 and an optical detection module 20.

[0055] like Figure 1 As shown, the electronic device 1 includes a display panel 10. The display panel 10 includes a substrate 100, a plurality of insulating layers 110, 120, 130, 140, 150, 160, 170, 181, 182 stacked in sequence, an active device array, a signal line and a pixel, wherein the number of insulating layers can be increased or decreased according to the use requirements. The display panel 10 includes a conventional area 11 and a functional area 12, and the storage capacitor C2 of the functional pixel PX2 in the functional area 12 can be less than or equal to the storage capacitor C1 of the conventional pixel PX1 in the conventional area 11. Therefore, the ability of the electronic device 1 or the display panel 10 to drive pixels can be improved. In addition, the electronic device 1 or the display panel 10 can have good display quality. It should be noted here that the display panel 10 of the present embodiment can be a liquid crystal display panel (LCD) technology that applies driving liquid crystal molecules, a self-luminous light emitting diode display panel (LED) technology or a self-luminous organic light emitting diode display panel (OLED) technology, but is not limited thereto.

[0056] Please refer to Figure 1, the display panel 10 includes a regular area 11 and a functional area 12. The functional area 12 can be an area defined at any position in the display area. In detail, the functional area 12 is defined as: an area that completely overlaps or partially overlaps the optical detection module 20 in the normal direction (also called the Z axis) of the substrate 100 perpendicular to the display panel 10. In other words, the optical detection module 20 is correspondingly arranged in the functional area 12. The regular area 11 is the display area outside the functional area 12. It should be noted here that for the sake of clarity and convenience of explanation, Figure 1 In the display area, a normal pixel PX1 is shown, and in the functional area 12, a functional pixel PX2 is shown. However, this embodiment does not Figure 1 The number of pixels or the structural settings shown are limited. Figure 1 In the embodiment, the optical detection module 20 is disposed outside the display panel 10 . In a possible embodiment, the optical detection module 20 may also be disposed inside the display panel 10 .

[0057] In the present embodiment, according to different requirements, the substrate 100 may be a hard substrate or a flexible substrate, and the material of the substrate 100 may include, for example, glass, quartz, ceramic, sapphire or plastic, but the present disclosure is not limited thereto. In another embodiment, the material of the substrate 100 may include a suitable opaque material. In some embodiments, when the substrate 100 is a flexible substrate, it may include a suitable flexible material, such as polycarbonate (PC), polyimide (PI), polypropylene (PP) or polyethylene terephthalate (PET), other suitable materials or a combination of the foregoing materials, but is not limited thereto. In addition, the light transmittance of the substrate 100 is not limited, that is, the substrate 100 may be a light-transmitting substrate, a semi-transmitting substrate or an opaque substrate.

[0058] In a direction perpendicular to the normal line of the substrate 100 (also referred to as the Z axis), the insulating layers 110, 120, 130, 140, 150, 160, 170, 181, 182 are sequentially disposed on the surface of the substrate 100. The insulating layers 110, 120, 130, 140, 150, 160, 170, 181, 182 may be a single layer or a multi-layer structure, and may include, for example, an organic material (such as silicon nitride), an inorganic material, or a combination thereof, but is not limited thereto.

[0059] The signal line is disposed on the substrate 100 and may be located between the insulating layers. The signal line includes, for example, a scan line SL and a data line DL (the data line DL is shown in FIG. Figure 6In other embodiments, the signal line also includes a power line, a common electrode line, a touch line or other lines, but is not limited thereto. Figure 1 As shown, the scan line SL is disposed on the insulating layer 120 and is located in the conventional area 11 and the functional area 12. In this embodiment, the material of the scan line SL and the data line DL may include a transparent conductive material or a non-transparent conductive material, such as indium tin oxide, indium zinc oxide, indium oxide, zinc oxide, tin oxide, metal materials (such as aluminum, molybdenum, copper, silver, etc.), other suitable materials or combinations thereof, but not limited thereto.

[0060] In this embodiment, the active device array may be disposed on the substrate 100 and may be located between insulating layers. The active device array may be electrically connected to the signal line and coupled to the normal pixel PX1 or the functional pixel PX2. The active device array includes a plurality of active devices (active device T is shown in FIG. Fig. 7A The active device is, for example, a thin film transistor having a semiconductor material. The semiconductor material includes, for example, a thin film transistor of amorphous silicon, low temperature polycrystalline silicon (LTPS) or metal oxide, or a combination of the above materials, but the present disclosure is not limited thereto. In some embodiments, different thin film transistors may have the above different semiconductor materials. In addition, the thin film transistor may include a top gate transistor, a bottom gate transistor, a dual gate transistor and a double gate transistor as needed, but is not limited thereto.

[0061] In this embodiment, the active device includes a semiconductor channel layer, a gate, and a source and a drain electrically connected to the semiconductor channel layer. In this embodiment, the gate can be electrically connected to the scan line SL, and the source can be electrically connected to the data line. The material of the gate can include molybdenum (Mo), titanium (Ti), tantalum (Ta), niobium (Nb), hafnium (Hf), nickel (Ni), chromium (Cr), cobalt (Co), zirconium (Zr), tungsten (W), aluminum (Al), copper (Cu), silver (Ag), other suitable metals, or alloys or combinations of the above materials, but not limited thereto. The source and drain materials may include transparent conductive materials or non-transparent conductive materials, such as indium tin oxide, indium zinc oxide, indium oxide, zinc oxide, tin oxide, metal materials (such as aluminum, molybdenum, copper, silver, etc.), other suitable materials or combinations thereof, but not limited thereto.

[0062] In this embodiment, the normal area 11 includes a plurality of normal pixels PX1 ( Figure 1 Each normal pixel PX1 has a normal pixel electrode PE1 and a normal common electrode CE1. The functional area 12 includes a plurality of functional pixels PX2 ( Figure 1 Each functional pixel PX2 has a functional pixel electrode PE2 and a functional common electrode CE2.

[0063] like Figure 1 As shown, the conventional common electrode CE1 and the functional common electrode CE2 are arranged on the insulating layer 170, and are respectively located in the conventional area 11 or the functional area 12. In the present disclosure, the conventional common electrode CE1 is arranged and / or located in the conventional area 11, which may be the conventional common electrode CE1 on the normal direction of the substrate 100 (for example: Z axis), at least the overlapping part of the conventional area 11, but not limited to this. By analogy, the functional common electrode CE2 is arranged and / or located in the functional area 12, which may be the functional common electrode CE2 on the Z axis of the substrate 100, at least the overlapping part of the functional area 12, but not limited to this. In other embodiments, other elements may also be located in other areas, so they will not be repeated below. Under the above-mentioned setting, the functional common electrode CE2 may overlap the optical detection module 20.

[0064] In this embodiment, the materials of the conventional common electrode CE1 and the functional common electrode CE2 may include transparent conductive materials or non-transparent conductive materials, such as indium tin oxide, indium zinc oxide, indium oxide, zinc oxide, tin oxide, metal materials (such as aluminum, molybdenum, copper, silver, etc.), other suitable materials or combinations thereof, but not limited thereto.

[0065] In the present embodiment, in the conventional area 11, the insulating layer 181 is disposed on the conventional common electrode CE1. In the functional area 12, the insulating layer 182 is disposed on the functional common electrode CE2. In the present embodiment, the conventional pixel electrode PE1 and the conventional common electrode CE1 may be located in different film layers. For example, in the conventional area 11, the conventional pixel electrode PE1 is disposed on the conventional common electrode CE1, and the conventional pixel electrode PE1 partially overlaps the conventional common electrode CE1. In the present embodiment, the functional pixel electrode PE2 and the functional common electrode CE2 are located in different film layers. For example, in the functional area 12, the functional pixel electrode PE2 is disposed on the functional common electrode CE2, and the functional pixel electrode PE2 partially overlaps the functional common electrode CE2. Under the above-mentioned setting, the functional pixel electrode PE2 may at least partially overlap the optical detection module 20. Thereby, an electric field may be generated between the pixel electrode and the common electrode to drive the display medium, and a storage capacitor may be generated between the pixel electrode and the common electrode, but the present embodiment is not limited thereto. The display panel 10 of the present embodiment is not limited to a liquid crystal display panel, and may also include a light emitting diode display panel or an organic light emitting diode display panel, but the present embodiment is not limited thereto.

[0066] Please refer to Figure 2A In the conventional area 11, the conventional pixel electrode PE1 and the conventional common electrode CE1 are arranged so that each conventional pixel PX1 has a first overlap ratio R1. The first overlap ratio R1 may be a ratio of an overlap area between the conventional pixel electrode PE1 and the conventional common electrode CE1 to an area of ​​the conventional common electrode CE1 when projected on the normal direction (also referred to as the Z axis) of the substrate 100 of the display panel 10, that is, (overlap area between the conventional pixel electrode PE1 and the conventional common electrode CE1) / (area of ​​the conventional common electrode CE1).

[0067] Please refer to Figure 2B In the functional area 12, the functional pixel electrode PE2 and the functional common electrode CE2 are arranged so that each functional pixel PX2 has a second overlapping ratio R2. The second overlapping ratio R2 may be a ratio of the overlapping area of ​​the functional pixel electrode PE2 and the functional common electrode CE2 to the area of ​​the functional common electrode CE2 when projected on the normal direction (also referred to as the Z axis) of the substrate 100 of the display panel 10, that is, (the overlapping area of ​​the functional pixel electrode PE2 and the functional common electrode CE2) / (the area of ​​the functional common electrode CE2).

[0068] It is worth noting that in order to improve the detection sensitivity and visual effect of the optical detection module 20 in the functional area 12, the area of ​​the functional pixel PX2 in the functional area 12 is increased. For example, in the normal direction (also referred to as the Z axis) of the substrate 100 of the display panel 10, the area of ​​any one of the multiple functional pixels PX2 is larger than the area of ​​any one of the multiple conventional pixels PX1. Therefore, the storage capacitor C2 of the functional pixel PX2 will increase. Therefore, the electronic device 1 or the display panel 10 disclosed in the present invention can adjust the storage capacitor C2 of the functional pixel PX2 in the functional area 12 by making the second overlap ratio R2 of at least part of the functional pixel PX2 less than or equal to the first overlap ratio R1 of at least part of the conventional pixel PX1. Thereby, the storage capacitor C2 of the functional pixel PX2 in the functional area 12 can be reduced to be less than or equal to the storage capacitor C1 of the conventional pixel PX1 in the conventional area 11. Therefore, the ability of the electronic device 1 or the display panel 10 to drive pixels can be improved. In addition, the electronic device 1 or the display panel 10 can improve the overall transmittance and have good display quality.

[0069] For details, please refer to Figure 1 , Figure 2A and Figure 2B . In the present embodiment, the second overlap ratio R2 may be equal to the first overlap ratio R1. However, the present embodiment may be manufactured by using a plurality of photomasks, so that the thickness H2 of the insulating layer 182 in the functional area 12 is greater than the thickness H1 of the insulating layer 181 in the conventional area 11. In the present embodiment, the thickness of the insulating layer may be the maximum vertical distance from the upper surface to the lower surface of the insulating layer on the Z-axis of the substrate 100. Under the above setting, compared with the conventional pixel PX1, the distance between the functional pixel electrode PE2 and the functional common electrode CE2 of the functional pixel PX2 may be greater than the distance between the conventional pixel electrode PE1 and the conventional common electrode CE1 of the conventional pixel PX1.

[0070] It is worth noting that according to the capacitance formula , since the distance between the functional pixel electrode PE2 and the functional common electrode CE2 of the functional pixel PX2 can be greater than the distance between the conventional pixel electrode PE1 and the conventional common electrode CE1 of the conventional pixel PX1, the storage capacitor C2 of the functional pixel PX2 can be smaller than the storage capacitor C1 of the conventional pixel PX1. In the present embodiment, C is capacitance, ε0 is vacuum permittivity, εr is relative permittivity, A is area, and d is distance. In this way, the storage capacitor C2 of the functional pixel PX2 in the functional area 12 is reduced to be less than or equal to the storage capacitor C1 of the conventional pixel PX1 in the conventional area 11. Therefore, the ability of the electronic device 1 or the display panel 10 to drive pixels can be improved. In addition, the electronic device 1 or the display panel 10 can have good display quality.

[0071] In other embodiments, in the conventional area 11, the conventional pixel electrode PE1 may be disposed between the insulating layer 170 and the insulating layer 181, and the conventional common electrode CE1 may be disposed on the insulating layer 181. In the functional area 12, the functional pixel electrode PE2 may be disposed between the insulating layer 170 and the insulating layer 182, and the functional common electrode CE2 may be disposed on the insulating layer 182, but the present invention is not limited thereto. That is, the display panel 10 disclosed herein may be an embodiment in which the pixel electrode is on top or the common electrode is on top, rather than in which the pixel electrode is on top. Figure 1 , Figure 2A or Figure 2B Limits shown.

[0072] Due to the electronic device 1 or display panel 10 of an embodiment of the present disclosure, it can be achieved by making the second overlap ratio R2 of at least a part of the functional pixel PX2 less than or equal to the first overlap ratio R1 of at least a part of the conventional pixel PX1. Or by the thickness of the insulating layer, the distance between the functional pixel electrode PE2 and the functional common electrode CE2 of the functional pixel PX2 can be greater than the distance between the conventional pixel electrode PE1 and the conventional common electrode CE1 of the conventional pixel PX1. Therefore, under the above-mentioned setting, the storage capacitor C2 of the functional pixel PX2 in the functional area 12 is reduced to be less than or equal to the storage capacitor C1 of the conventional pixel PX1 in the conventional area 11. Therefore, the ability of the electronic device 1 or display panel 10 to drive pixels can be improved. In addition, the electronic device 1 or display panel 10 can improve the overall transmittance and have good display quality.

[0073] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component numbers and some contents of the previous embodiments, wherein the same numbers are used to represent the same or similar components, and the description of the same technical contents is omitted. The description of the omitted parts can be referred to the previous embodiments, and the following embodiments will not be repeated.

[0074] Figure 3A It is a partially enlarged cross-sectional schematic diagram of a conventional pixel according to another embodiment of the present disclosure. Figure 3B This is a partially enlarged cross-sectional schematic diagram of a functional pixel of another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 3A and Figure 3B The display panel 10A of the present embodiment may be substantially similar to Figure 2A and Figure 2BTherefore, the same and similar components in the two embodiments are not repeated here. In the conventional area 11 of the display panel 10A, the conventional pixel electrode PE1 and the conventional common electrode CE1 are separated by the insulating layer 181 and are located in different film layers. That is, the conventional pixel electrode PE1 overlaps the conventional common electrode CE1 on the Z axis. For example, in the conventional area 11, for example, a fringe field switching (FFS) technology is used to drive the display medium.

[0075] In the functional area 12 of the display panel 10A, the functional pixel electrode PE2 and the functional common electrode CE2 are located in the same film layer. That is, the functional pixel electrode PE2 and the functional common electrode CE2 are located on the insulating layer 182 and are arranged alternately adjacent to each other, or are located on the same horizontal plane. From another perspective, the functional pixel electrode PE2 does not overlap the functional common electrode CE2 on the Z axis. For example, in the functional area 12, for example, the technology of driving the display medium using in-plane switching (IPS) is used.

[0076] In this embodiment, the first overlapping ratio R1 is the same as that described above, so it is not repeated here. The second overlapping ratio R2 can be the ratio of the overlapping area between the functional pixel electrode PE2 and the functional common electrode CE2 to the area of ​​the functional common electrode CE2 on the Z axis, that is, (the overlapping area between the functional pixel electrode PE2 and the functional common electrode CE2) / (the area of ​​the functional common electrode CE2 on the Z axis) projected on the X axis (perpendicular to the Z axis or perpendicular to the normal direction of the substrate 100). Under the above setting, since the overlapping area between the functional pixel electrode PE2 and the functional common electrode CE2 can depend on the thickness of the functional pixel electrode PE2 and the functional common electrode CE2, the overlapping area can be further reduced, thereby reducing the second overlapping ratio R2.

[0077] Since the second overlap ratio R2 of the functional area 12 using the in-plane switching technology can be less than the first overlap ratio R1 of the conventional area 11 using the fringe field switching technology, the storage capacitance C2 of the functional pixel PX2 in the functional area 12 is reduced to be less than or equal to the storage capacitance C1 of the conventional pixel PX1 in the conventional area 11. Therefore, the ability of the display panel 10A to drive pixels can be improved. In addition, the display panel 10A can have good display quality. In addition, the display panel 10A can obtain excellent technical effects similar to those of the above-mentioned embodiments.

[0078] Figure 4 This is a partially enlarged cross-sectional schematic diagram of a functional pixel of another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 4 The display panel 10B of this embodiment may be substantially similar to Figure 2BThe display panel 10 of the present invention is provided, and therefore the same and similar components in the two embodiments are not repeated here. In the functional pixel PX2 of the present embodiment, the functional pixel electrode PE2 and the functional common electrode CE2 are located in different film layers. On the Z axis, the finger-shaped portion PE21 of the functional pixel electrode PE2 is outside the finger-shaped portion CE21 of the functional common electrode CE2. That is to say, on the Z axis, the finger-shaped portion PE21 of the functional pixel electrode PE2 does not overlap the finger-shaped portion CE21 of the functional common electrode CE2. In this way, the overlapping area of ​​the functional pixel electrode PE2 and the functional common electrode CE2 can be further reduced, thereby reducing the second overlapping ratio R2. Thereby, the storage capacitor C2 of the functional pixel PX2 can be reduced. Therefore, the ability of the display panel 10B to drive pixels can be improved. In addition, the display panel 10B can have good display quality. In addition, the display panel 10B can achieve excellent technical effects similar to those of the above-mentioned embodiments.

[0079] Figure 5 This is a partially enlarged cross-sectional schematic diagram of a functional pixel of another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 5 The display panel 10C of this embodiment may be substantially similar to Figure 4 The display panel 10B is a display panel 10B, so the same and similar components in the two embodiments are not repeated here. In this embodiment, the functional pixel electrode PE2 partially overlaps the functional common electrode CE2. For example, in the functional pixel PX2, the functional pixel electrode PE2 and the functional common electrode CE2 are located in different film layers. On the Z axis, the finger portion PE21 of the functional pixel electrode PE2 overlaps the functional common electrode CE2 (or its finger portion, but not limited to this). In addition, the functional pixel electrode PE2 also includes a finger portion PE22, and the finger portion PE22 is located outside the functional common electrode CE2. That is, on the Z axis, the finger portion PE22 does not overlap the functional common electrode CE2 (or its finger portion, but not limited to this). In this way, the overlapping area of ​​the functional pixel electrode PE2 and the functional common electrode CE2 can be adjusted, that is, there is an effect of adjusting the second overlapping ratio R2. Thereby, the display panel 10C can strike a balance between reducing the storage capacitance C2 of the functional pixel PX2 or maintaining the effective storage capacitance C2. Therefore, the ability of the display panel 10C to drive pixels can be improved. In addition, the display panel 10C can have good display quality. In addition, the display panel 10C can achieve excellent technical effects similar to those of the above-mentioned embodiment.

[0080] Figure 6 This is a partially enlarged top view of another embodiment of the functional pixel disclosed herein. For the sake of clarity and convenience of description, Figure 6Some elements are omitted. The components of the display panel 10D of this embodiment that are the same as or similar to those in the previous embodiment are not repeated here. The functional pixel electrode PE2 of the functional pixel PX2 of this embodiment has a finger portion PE21 extending along the X-axis and a connection portion PE23 connecting the finger portion PE21. The connection portion PE23 extends along the Y-axis. The display panel 10D includes a data line DL extending along the Y-axis, and the data line DL is arranged in parallel with the connection portion PE23 or the connection portion CE23. In this embodiment, the X-axis is perpendicular to the Y-axis, and the Y-axis is perpendicular to the Z-axis.

[0081] The functional common electrode CE2 has a finger portion CE21 extending along the X axis and a connection portion CE23 connecting the finger portion CE21. The connection portion CE23 extends along the Y axis. In this embodiment, the finger portion CE21 of the functional common electrode CE2 and the finger portion PE21 of the functional pixel electrode PE2 are alternately arranged on the Y axis and do not overlap on the Z axis. Thereby, the storage capacitance of the functional pixel PX2 can be reduced.

[0082] In the present embodiment, the connection portion PE23 of the functional pixel electrode PE2 may overlap the connection portion CE23 of the functional common electrode CE2 on the Z axis. In detail, on the Z axis, the connection portion PE23 may be located in the connection portion CE23. The connection portion PE23 may have a width W1. The connection portion CE23 may have a width W2. In the present embodiment, the width may be the maximum straight-line distance between two opposite sides of the connection portion on the X axis.

[0083] In this embodiment, the width W2 of the connection portion CE23 may be greater than the width W1 of the connection portion PE23, but the present invention is not limited thereto. In other embodiments, the width W1 of the connection portion PE23 may be greater than the width W2 of the connection portion CE23. In other words, the widths of the connection portions of the two layers of electrodes are different from each other and have a width difference. In addition, the edges of the connection portion PE23 and the connection portion CE23 do not overlap. Figure 6 For example, there may be a width difference between the right edge of the connection portion PE23 and the right edge of the connection portion CE23, or there may be a width difference between the left edge of the connection portion PE23 and the left edge of the connection portion CE23, but the embodiment is not limited thereto.

[0084] In this embodiment, the value of the width difference between the connection portion PE23 and the connection portion CE23 can be In other embodiments, the value of the width difference between the connection portion PE23 and the connection portion CE23 may be . For example, the connection portion PE23 may be located in the connection portion CE23, and the distance between the right side of the connection portion PE23 and the right side of the connection portion CE23 is 1μm, 5μm, 10μm, 15μm or 20μm, but not limited thereto. Alternatively, the connection portion CE23 may be located in the connection portion PE23, and the distance between the left side of the connection portion CE23 and the left side of the connection portion PE23 is 1μm, 5μm, 10μm, 15μm or 20μm, but not limited thereto. It should be noted here that the above is a schematic illustration and is not intended to limit the numerical range of the implementation of the present disclosure. Under the above-mentioned setting, when an offset or tolerance occurs in the manufacturing process, its impact on the overlapping area of ​​the functional pixel electrode PE2 and the functional common electrode CE2 can be reduced, and the overlapping ratio expected by the user can be maintained.

[0085] In this way, the overlapping area of ​​the functional pixel electrode PE2 and the functional common electrode CE2 can be adjusted, that is, the effect of adjusting the second overlapping ratio R2 can be achieved. Thereby, the storage capacitor C2 of the functional pixel PX2 can be reduced. In addition, when the manufacturing process produces an offset or tolerance, the display panel 10D can maintain the expected overlapping ratio of the functional pixel electrode PE2 and the functional common electrode CE2. Therefore, the ability of the display panel 10D to drive pixels can be improved. In addition, the display panel 10D can have a good display quality. In addition, the display panel 10D can obtain excellent technical effects similar to those of the above-mentioned embodiments.

[0086] Fig. 7A FIG. 4 is a top view schematically showing a functional pixel according to another embodiment of the present disclosure. Figure 7B for Fig. 7A A schematic partial enlarged top view of area A1. Figure 7C for Fig. 7A For the sake of clarity and convenience of description, Fig. 7A , Figure 7B and Figure 7C Several components are omitted from the illustration. The display panel 10E of this embodiment is substantially similar to Figure 6The display panel 10D is a display panel 10D, so the same and similar components in the two embodiments are not repeated here. In this embodiment, one of the two opposite edges of the connection portion PE23 and the connection portion CE23 or the connection portion PE24 and the connection portion CE24 overlaps or is aligned, while the other does not overlap. In detail, the functional pixel PX2 is located between two data lines DL extending along the Y axis and between two scan lines SL extending along the X axis. The active device T is electrically connected to the scan line SL or the data line DL, and is coupled to the functional pixel electrode PE2. In this embodiment, the functional pixel electrode PE2 includes a plurality of finger-shaped portions PE21 and connection portions PE23 and PE24 connecting the plurality of finger-shaped portions PE21 at opposite ends of the finger-shaped portions PE21. The functional common electrode CE2 includes a plurality of finger-shaped portions CE21 and connection portions CE23 and CE24 connecting the plurality of finger-shaped portions CE21 at opposite ends of the finger-shaped portions CE21.

[0087] In this embodiment, the finger portion CE21 of the functional common electrode CE2 and the finger portion PE21 of the functional pixel electrode PE2 are alternately arranged on the Y axis and do not overlap on the Z axis. In addition, the finger portion PE21 of the functional pixel electrode PE2 overlaps the functional common electrode CE2 at the adjacent scanning line SL. In this way, the display panel 10E can strike a balance between reducing the storage capacitance C2 of the functional pixel PX2 or maintaining the effective storage capacitance C2.

[0088] Please refer to Figure 7B Area A1 and Figure 7C FIG. 1 is an enlarged schematic diagram of the area A2 of FIG. 1 . In the present embodiment, the connection portion PE23 (or the connection portion PE24) of the functional pixel electrode PE2 is located in the connection portion CE23 (or the connection portion CE24) of the functional common electrode CE2, and the width W1 of the connection portion PE23 (or the connection portion PE24) is smaller than the width W2 of the connection portion CE23 (or the connection portion CE24). In other embodiments, the connection portion CE23 (or the connection portion CE24) may also be located in the connection portion PE23 (or the connection portion PE24). The width of the connection portion and the width difference thereof are as described above, so they are not repeated here.

[0089] like Figure 7B As shown, the left edge of the connection portion PE23 may overlap the left edge of the connection portion CE23, and the right edge of the connection portion PE23 may have a width difference with the right edge of the connection portion CE23. Figure 7C As shown, the right edge of the connection portion PE24 may overlap the right edge of the connection portion CE24, and the left edge of the connection portion PE24 may have a width difference with the left edge of the connection portion CE24. In this embodiment, the value of the width difference may be In other embodiments, the value of the width difference between the connection portion PE23 and the connection portion CE23 may be .

[0090] Under the above setting, when a deviation to the right occurs during the manufacturing process, the connection portion PE23 can move to Figure 7B The finger portion PE21 is moved to the right, so that part of the finger portion PE21 overlaps the connection portion CE23. That is, the overlapping ratio of the functional pixel electrode PE2 and the functional common electrode CE2 can be increased. Figure 7C The connection portion PE24 in the display panel 10E can be moved to the right so that part of the connection portion PE24 does not overlap the connection portion CE24. Under the above setting, the width difference between the connection portion PE24 and the connection portion CE24 can be increased, or the overlapping part can be reduced. From another perspective, the overlapping ratio of the functional pixel electrode PE2 and the functional common electrode CE2 can be reduced. In this way, the influence of the offset or tolerance generated in the manufacturing process on the overlapping ratio of the functional pixel electrode PE2 and the functional common electrode CE2 can be reduced. The display panel 10E can maintain the expected overlapping ratio of the functional pixel electrode PE2 and the functional common electrode CE2. Therefore, the ability of the display panel 10E to drive pixels can be improved. In addition, the display panel 10E can have good display quality. In addition, the display panel 10E can achieve excellent technical effects similar to the above-mentioned embodiments.

[0091] In summary, in the display panel and electronic device of one embodiment of the present disclosure, since the area of ​​the functional pixel is larger than the area of ​​the conventional pixel, the second overlap ratio of at least part of the functional pixel can be made less than or equal to the first overlap ratio of at least part of the conventional pixel. In this way, the storage capacitance of the functional pixel in the functional area can be reduced and can be less than or equal to the storage capacitance of the conventional pixel in the conventional area. Therefore, the ability of the display panel or the electronic device including it to drive the pixel can be improved. In addition, the electronic device or display panel can have good display quality. In addition, the electronic device or display panel can make the distance between the functional pixel electrode and the functional common electrode of the functional pixel greater than the distance between the conventional pixel electrode and the conventional common electrode of the conventional pixel by adjusting the thickness of the insulating layer. Therefore, the storage capacitance of the functional pixel in the functional area can be controlled. In addition, the electronic device or display panel can control the overlap ratio by using in-plane switching technology and edge field switching technology. Therefore, the storage capacitance of the functional pixel can be reduced and can be less than or equal to the storage capacitance of the conventional pixel. In addition, the electronic device or display panel can adjust the second overlap ratio by making the functional pixel electrode overlap or not overlap the functional common electrode. Thereby, the electronic device or display panel can strike a balance between reducing the storage capacitance of the functional pixel or maintaining the effective storage capacitance. In addition, the functional pixel electrode and the functional common electrode can reduce the influence of the offset or tolerance generated in the manufacturing process on the overlapping ratio of the functional pixel electrode and the functional common electrode by making the overlapping part have a width difference. Thereby, the electronic device or display panel can maintain the expected overlapping ratio of the functional pixel electrode and the functional common electrode. Therefore, the ability of the electronic device or display panel to drive pixels can be improved. In addition, the electronic device or display panel can have good display quality.
