First, the movable portion 26 (see FIG. 1), the movable portion 30b, and the movable portion 31 The movements of the movable parts 26, 32b, and 33b are defined as follows. The angle formed by the movable part 30a and the part 22 is defined as a first angle M1. The angle formed by the movable part 31b and the part 31a is defined as a second angle M2. The angle formed by the movable part 32a and the movable part 32b is a third angle M3. The angle formed by the movable part 33b and the part 33a is defined as a fourth angle M4. The angle formed by 3a and the component 34a is a fifth angle M5.

[0066] First, the electronic device 10 is in a first state in which the housing 27 is folded, as shown in FIG. 3, the description will be given with a focus on the movable module 30. 3D is an enlarged view of the movable module 30 in FIG.

[0067] When the housing 27 is in the first state, the component 32a has the component 33a stored in the space 32c. and the part 33a is maintained in a state where the part 34a is not accommodated in the space 33c. When the housing 27 is maintained in the first state, it is preferable that the second angle M2 is approximately vertical. It is nice.

[0068] When the housing 27 is in the first state, the component 31a is in the first state as shown in FIG. A fourth space 60 is formed by the parts 32a and 33a, and the fourth space 6 It is preferable that a part of the display panel 11 is located inside the window 10.

[0069] When the housing 27 is in the first state, the display area 11c is displayed as a curved display panel 11. The fourth space 60 can accommodate the magnetrons so that the magnetrons are not smaller than the radius of curvature r. When the body 27 is in the first state, the movable module 30 moves the display area 11 of the display panel 11 toward the display area 12. It is possible to control the radius of curvature of the display panel so that it does not become smaller than the radius of curvature r of the display panel 1c. The display panel 11 is accommodated in the fourth space 60 so that the display panel 11 does not bend beyond the radius of curvature r. As a result, wiring, inorganic films, organic films, organic resin films, and the like of the display panel 11 are destroyed. In order to more efficiently accommodate the display area 11c in the fourth space 60, For this purpose, it is preferable that the display area 11a is fixed to the component 20a. The display panel 11 is fixed to the component 20a so that the display area 11c is defined as the fourth space 6. It can be stored efficiently within 0.

[0070] Next, in FIG. 3B, as an example, when the first angle M1 is approximately 45 degrees (including 45 degrees), In FIG. 3B, it is preferable that the second angle M2 is kept substantially perpendicular. Also, the third angle M3 is large, and the fourth angle M4 and the fifth angle M5 are small. By maintaining the second angle M2 substantially perpendicular, the third angle M3 to the fifth angle M5 are In addition, when the second angle M2 is not substantially perpendicular, the third angle M3 to the fifth angle M4 are changed. The M5 changes differently than the above.

[0071] Next, in FIG. 3C, as an example, a case where the first angle M1 is approximately vertical (including vertical) is shown. In FIG. 3(C), it is preferable that the second angle M2 is larger than that in FIG. 3(B). Also, the third angle M3 is small, and the fourth angle M4 and the fifth angle M5 are large. Since the second angle M2 is smaller than that in FIG. 3B, the third angle M3 to the fifth angle M4 are In addition, when the second angle M2 is reduced, the third angle M3 to the third angle M4 are changed. The fifth angle M5 varies differently than described above.

[0072] Next, in FIG. 4A, as an example, the first angle M1 is approximately 135 degrees (including 135 degrees). In FIG. 4(A), the second angle M2 is larger than that in FIG. 3(C). It is preferable that the third angle M3 is large, and the fourth angle M4 and the fifth angle The second angle M2 is larger than that in FIG. 3(C), so that the third angle M5 is smaller. Degrees M3 to fifth angle M5 vary.

[0073] Finally, in FIG. 4B, as an example, the first angle M1 is approximately 180 degrees (including 180 degrees). 4B shows the case where the housing 27 changes to the second state. 4(A) , the second angle M2 becomes larger and reaches a maximum angle. The maximum angle is The third angle M3 is also the maximum angle. The fifth angle M5 becomes smaller and becomes the minimum angle. The minimum angle is approximately 0 degrees (including 0 degrees). Therefore, the part 33a is stored in the part 34a, and the part 32a is stored in the part 34a. The parts 30a, 31a, and 32a are stored in the display panel 11. and supports the display panel 11. The portion, part 33a, or part 34a is in contact with the back surface of the part 22 or is positioned parallel to the part 22. It is preferred that the device has a surface on which the sensor is placed.

[0074] It should be noted that FIG. 3(B), (C) and FIG. 4(A) show the housing 27 in the third state. When the housing 27 is in the second state or the third state, the display areas 11a to 11c are The display data can be displayed.

[0075] 3 and 4, the angles are approximately 0 degrees, approximately 45 degrees, approximately 90 degrees, approximately 135 degrees, and approximately 160 degrees, respectively. Although an example of approximately 180 degrees has been shown, the first angle M1 held by the housing 27 is not limited to the above. The first angle can be any angle between approximately 0 degrees and approximately 180 degrees. do.

[0076] Next, in FIG. 5(A) to FIG. 5(E), the first angle M1 and the cutout area 2 of the part 24 are The relationship between the protruding structure 22b of the component 22 and the protruding structure 22a will be described. For the sake of clarity, FIG. 5 shows only the movable portion 26, the structure 22b, the cutout region 24a, and the first space 22. In FIG. 5, the position Pna closest to the movable part 26 and the structure 22b The following description will be given with attention to the position Pnb, which is the furthest position from the movable part 26 in the first space 22a. . n is a positive integer greater than or equal to 1.

[0077] The size and width of the component 24 do not change. The position of the protruding structure 22b provided on the part 22 is not changed. The position where the structure 22b is placed does not change. Also, the structure 22b has a width S1 from the center of the structure 22b. The figure shows an example of a structure with a semicircular cross section, but it can also be a columnar structure. The structure 22b may have any shape, and the shape is not limited. For example, when the first space 22a is formed in the part 22, By reducing the number of parts, the cost of parts for electronic devices can be reduced. In addition, when the part 24 has a protruding structure, the cutout area The region may be a configuration that part 22 has.

[0078] In FIG. 5A, when the housing 27 maintains the first state, the first angle M1 is approximately 0 degrees. The part 22 has a first space 22a for accommodating the part 24, and The part 24 can slide in the first space 22a. The first angle M1 of the housing 27 is changed to the display area 11c. A position shift occurs, and the position of the display area 11b moves. The display area 11b moves, and the part 24 slides according to the distance the display area 11b moves. The display area 11a is fixed to the component 20a up to the range of the position L1. The positional relationship between the display areas 11a, 11b, and 11c is as shown in FIG. It is possible.

[0079] When the housing 27 is in the first state, the curved surface of the display area 11c is smaller than the minimum curvature radius r. It is preferable that the display area is controlled so as not to become smaller. For example, the display area 11a and the display area When the display area 11c is in contact with or faces the display area 11b, the display area 11c is a curved surface having a radius of curvature larger than r. Therefore, a part of the display area 11b is formed at a distance of twice the radius of curvature r ( In other words, if the display area 11c has a radius of curvature r, By forming a larger curved surface, a part of the display area 11b and the display area 11c , a position shift occurs.

[0080] When the housing 27 is maintained in the first state, the distance caused by the positional deviation is the first space The distance that the part 24 housed in the movable motor 22a slides is equal to the distance that the part 24 slides. The module 30 can control the display area 11c so that it does not become smaller than the radius of curvature r. In addition, the protruding structure 22b of the part 22 and the notch 22b of the part 24 can be used as a bonding material. When the side surface of the region 24a that is farther from the movable portion 26 comes into contact with the movable portion 26, the movable portion 26 slides toward the movable portion 26. The movable range of the part 24 that moves in the guide is limited. At the position P1a closest to the movable portion 26, the movable range of the sliding movement of the part 24 is restricted. Therefore, it is preferable to determine the movable range of the sliding movement of the part 24 as follows. By controlling the curvature of the display panel 11, it is possible to control the curvature of the display panel 11 so that the curvature does not become smaller than the radius r. The display area 11b and the part 24 to which the display area 11b is fixed are movable parts 2 It is preferable that the sliding movement is made to positions P1a and P1b close to 6.

[0081] Next, in FIG. 5B, a case where the first angle M1 changes from approximately 0 degrees to approximately 45 degrees will be described. The positional deviation occurring in the display panel 11 is determined by the positional deviation of the display panel 11 according to the first angle M1. When the first angle M1 changes from approximately 0 degrees to approximately 45 degrees, the position of the display area 11b The display area 11c slides a distance d. The part 24 to which the wire 11b is fixed is moved from the position P1a to the position P2a at a position close to the movable part 26. , and at a position far from the movable part 26, it slides from position P1b to position P2b. Move.

[0082] Next, in FIG. 5C, a case where the first angle M1 changes from approximately 0 degrees to approximately 90 degrees will be described. When the first angle M1 changes from approximately 0 degrees to approximately 90 degrees, the display area 11b, the display area The display area 11c slides a distance 2d. The part 24 to which the movable part 26 is fixed slides from a position P1a to a position P3a at a position close to the movable part 26. The movable portion 26 slides from position P1b to position P3b. do.

[0083] Next, in FIG. 5(D), the first angle M1 changes from approximately 0 degrees to approximately 135 degrees. When the first angle M1 changes from approximately 0 degrees to approximately 135 degrees, the display area 11b, the display The display area 11c slides a distance 3d. The part 24 to which the movable part 26 is fixed has a range from the position P1a to the position P4a in the vicinity of the movable part 26. , and at a position far from the movable part 26, it slides from position P1b to position P4b. Move.

[0084] When the first angle M1 is greater than approximately 90 degrees and smaller than approximately 180 degrees, the position L1 is This is because the display panel is flexible and the display position may shift. This is because a stress acts on the panel 11 in a direction away from the movable portion 26 with the position L as a base point.

[0085] Next, in FIG. 5E, the first angle M1 changes from approximately 0 degrees to approximately 180 degrees. In other words, when the first angle M1 reaches approximately 180 degrees, the housing 27 is in the second state. When the first angle M1 changes from approximately 0 degrees to approximately 180 degrees, the display area 11b, the display The display area 11c slides a distance 4d. The part 24 to which the movable part 26 is fixed has a range from position P1a to position P5a in the vicinity of the movable part 26. , and at a position far from the movable portion 26, it slides from position P1b to position P5b. When the first angle M1 reaches approximately 180 degrees, the display panel 11 forms a flat surface. Therefore, the positional deviations occurring in each of FIGS. 5(A) to 5(D) are all eliminated.

[0086] Next, the electronic device 10 will be described in detail with reference to FIG. 6(A). FIG. 6(B) is a top view of the child device 10, FIG. 6(B) is a development view of the movable module 30, and FIG. A cross-sectional view of the electronic device 10 will now be described.

This can provide the effect of simplifying the assembly process and reducing the number of parts. do.

[0088] The movable part 26 is composed of a part 25, a part 25a, and a part 25b. a is fixed to the part 20, and part 25b is fixed to the part 22. It is preferable that the movable module 30 is disposed on the outside of both ends of the movable part 26. A movable module 30 may be disposed in the

[0089] The components 23, 21a, and 21b function as a frame. In the case where the display panel 11 is flexible, the display panel 11 is provided with a display area 11b of the display panel 11, ... and a display area 11b of the display panel 11. The display area 11b is fixed to the component 24, and the display area 11b overlaps with the component 23. This can prevent the display panel 11 from falling off the frame.

[0090] FIG. 6B shows the movable module 30 having the same configuration as that described in FIG. 1B. In addition, the part 34a only needs to be connected to a part of the part 33a. In FIG. 6A, the part 34a is fixed to the part 33a in two areas. The movable parts 30b, 31b, 32b, and 33b are connected to each other by using hinges or the like. For example, the movable part 30b is connected to the part 30a in two areas. The movable portion 31b is fixed to the part 31a and the part 32 in two regions. The movable part 32b is fixed to the parts 32a and 33a in two regions. The movable part 33b is fixed in two areas to the part 33a. It is fixed to part 34a.

[0091] For FIG. 6(C), the explanation of the electronic device 10 explained in FIG. 2(A) can be taken into consideration. The part 20a is arranged so that the region 11d is contained in a fifth space formed by the parts 20 and 20a. The component 21b has an opening 20s1 for receiving the display panel 11 and the component 21a. , and preferably in contact with component 20.

[0092] In FIG. 7(A), an electronic device 10A different from that in FIG. 6(A) will be described. In FIG. 7(A), In the embodiment, the part 21 is formed as a single part. By reducing the number of parts, the fixture 40 The part 20a is formed by dividing the area 11d into two parts. 20, and an opening 20s1 for receiving the fifth space formed by the part 20a. Moreover, the component 21 is preferably in contact with the display panel 11 and the component 20a.

[0093] In FIG. 7C, an opening 20s1 is provided that is wide enough for electronic component 50 to pass through. It is preferable that the component 21 is disposed at a position overlapping the opening 20s1.

[0094] In FIG. 8(A), an electronic device 10B different from that in FIG. 7(A) will be described. In the fifth space formed by the component 20a and the component 20, the region 11d is accommodated in the fifth space formed by the component 20a. The component 21 has an opening 20s3 for receiving the display panel 11 and the component 20. It is preferable that the component 21 contacts with a. Note that in Fig. 8, the component 21 is shown as a transparent component.

[0095] The opening 20s3 has a first width through which the thickness S3 of the display part of the display panel 11 passes and a second width through which the electronic part It is preferable that the thickness of the product 50 passes through the second width S4. The opening 20s3 has a first width S3 and a second width S4. The component 20a can support the display panel 11 over a wide area. 4, the display panel 11 can be used as the electronic device 10B even after the electronic component 50 is mounted. This makes it easier to assemble the device.

[0096] In FIG. 9(A), an electronic device 10C different from that in FIG. 7(A) will be described. In FIG. 9(A), In FIG. 9C, the component 20a has an opening 20s4. A detailed explanation will be given.

[0097] In the electronic device 10C, the electronic component 52 mounted in the region 11d is disposed in the opening 20s4. The display panel 11 is electrically connected to an electronic component 53 via an electronic component 52. For example, the electronic component 52 or the electronic component 53 may be a connector. Since the panel 11 is electrically connected to the electronic component 53 via the electronic component 52, the region 11d is The curved surface may not be included. By not including a curved surface, control of the radius of curvature can be omitted. In addition, the adhesion between the display panel 11 and the component 21 can be improved. This makes it easier to assemble the device 11C.

[0098] By using FIGS. 1 to 9, a foldable electronic device having a novel configuration can be provided. Furthermore, the electronic device can control the radius of curvature of the flexible display panel. As a method for controlling the radius of curvature of the display panel, the movable module 30 and the part 24 are used. When the display panel has a curved surface, a part of the display panel slides. The display panel can move a distance equal to the amount of misalignment. The curved surface of the filter prevents the display panel from being damaged by stress caused by the curved surface. In addition, the display panel can be prevented from falling off from the electronic device. Equipment can be provided.

[0099] The structures and methods described in this embodiment mode may be appropriately combined with the structures and methods described in other embodiment modes. They can be used in combination.

[0100] (Embodiment 2) In this embodiment mode, an example of the display panel illustrated in the above embodiment mode will be described.

[0101] [Configuration example] FIG. 10A shows a top view of a display panel 700. The display panel 700 is made of a sealing material 7 The first substrate 701 and the second substrate 705 are bonded together by a metal plate 12. In the region sealed by the plate 701, the second substrate 705, and the sealant 712, A pixel section 702, a source driver 704, and a gate driver 706 are provided on a substrate 701. The pixel portion 702 is provided with a plurality of display elements.

[0102] In addition, an FPC 716 (FP C: Flexible printed circuit) is connected to the terminal portion 708. The FPC 716 is provided to connect the pixel 702 to the terminal portion 708 and the signal line 710. Various signals are supplied to each of the display unit 702, the source driver 704, and the gate driver 706. Supplied.

[0103] A plurality of gate drivers 706 may be provided. The source driver 704 is formed separately on a semiconductor substrate or the like and packaged. The IC chip may be in the form of an IC chip. The IC chip may be mounted on the first substrate 701 or on the FPC 16. In addition, the IC chip can be mounted on a display device in which the pixel portion 702 displays display data. It can be mounted on a surface (back side) different from the display surface to be displayed.

[0104] The pixel section 702, the source driver 704, and the gate driver 706 each include a transistor. It is possible.

[0105] Examples of the display element provided in the pixel portion 702 include a liquid crystal element and a light emitting element. As the liquid crystal element, a transmissive liquid crystal element, a reflective liquid crystal element, a semi-transmissive liquid crystal element, etc. are used. In addition, the light emitting element can be a micro LED (Light Emitting Diode). ing Diode), OLED (Organic LED), QLED (Quantu Examples of the light emitting element include self-luminous light emitting elements such as m-dot LEDs and semiconductor lasers. Shutter type or optical interference type MEMS (Micro Electro Mechanical Systems) ical Systems), microcapsules, electrophoresis, and electro Using display elements that use the wetting method or electronic powder method, etc. It is also possible.

[0106] In FIG. 10B, the terminal portion 708 of the display panel 700 shown in FIG. FIG. 10B shows the connection of the pixel section that displays the display data. The terminal portion 708 can be exposed on the rear surface of the terminal portion 702 by using a through electrode. 08 and FPC716 connections use anisotropic conductive film containing conductive particles CP with a diameter of about 3 μm. A driver IC or a connector is connected to the terminal section 708. Good too.

[0107] [Cross-section example] In the following, a configuration in which a liquid crystal element and an EL element are used as a display element will be described with reference to FIGS. 11 to 13 are respectively the chain diagrams shown in FIG. 11 and 12 are cross-sectional views taken along the line QR. FIG. 13 shows a configuration using an EL element.

[0108] [Explanation of common parts of the display panel] The display panel 700 shown in FIG. 11 to FIG. 13 includes a wiring portion 711 and a pixel portion 702. The pixel 701 includes a source driver 704 and a terminal section 708. The lead wiring section 711 is The pixel portion 702 includes a transistor 750 and a capacitor 790. The source driver 704 includes a transistor 752. In FIG. This shows the case where there is no

[0109] As an example, the transistors 750 and 752 are highly purified and have an oxygen vacancy. The transistor has a metal oxide in a semiconductor layer that suppresses the formation of a metal oxide. This allows the retention time of electrical signals such as image signals to be extended, and the write interval is reduced when the power is on. This allows the frequency of refresh operations to be reduced, resulting in lower power consumption. In the following, a transistor having a metal oxide in the semiconductor layer is referred to as an O This is called an S transistor.

[0110] The transistor used in this embodiment has a relatively high field-effect mobility and therefore has a high For example, if such a transistor capable of high speed driving is used in a display panel, By using this, the switching transistor in the pixel section and the driver transistor in the drive circuit section can be The transistors can be formed on the same substrate.

[0111] That is, a semiconductor device formed from a silicon wafer or the like is used as a separate driving circuit. Since there is no need to use a pixel electrode, the number of components in the semiconductor device can be reduced. However, by using transistors that can be driven at high speed, it is possible to provide high-quality images. Cut.

[0112] Note that various types of transistors can be used as the transistor. There is no limitation on the type of transistor to be used. For example, amorphous silicon, polycrystalline silicon, Non-crystalline silicon, such as microcrystalline (also called semi-amorphous) silicon, A thin film transistor (TFT) having a single crystal semiconductor film can be used. There are various advantages to using silicon carbide. For example, it can be grown at a lower temperature than single crystal silicon. Since the manufacturing process can be performed in a small space, it is possible to reduce the manufacturing cost or to increase the size of the manufacturing equipment. Since the size of the display panel can be increased, it can be manufactured on a large substrate. Since the manufacturing temperature is low, the resulting product has high heat resistance. Therefore, a weak substrate can be used. A transistor can be manufactured on the substrate. Then, the light transmission in the display element can be controlled by using the transistor on the substrate. Alternatively, since the film thickness of the transistor is thin, it is possible to control the A part of the film that is made of the reflective layer can transmit light. This makes it possible to improve the aperture ratio. can.

[0113] In addition, by using a catalyst (such as nickel) when producing polycrystalline silicon, It is possible to further improve the crystallinity and manufacture transistors with good electrical characteristics. As a result, the gate driver circuit (scanning line driver circuit) and the source driver circuit (signal line driver circuit ), signal processing circuits (signal generation circuit, gamma correction circuit, DA conversion circuit, etc.) are integrated on the board. It can be formed.

[0114] In addition, when manufacturing microcrystalline silicon, a catalyst (such as nickel) is used to form the crystal. This makes it possible to further improve the crystallinity and manufacture transistors with good electrical characteristics. In this case, it is possible to improve the crystallinity by simply applying heat treatment without laser irradiation. As a result, part of the source driver circuit (analog switch, etc.) and the gate driver The driver circuit (scanning line driver circuit) can be formed integrally on the substrate. When laser irradiation is not performed for this purpose, unevenness in the crystallinity of the silicon can be suppressed. Therefore, an image with improved quality can be displayed.

[0115] However, polycrystalline silicon and microcrystalline silicon can be produced without using a catalyst (such as nickel). It is possible.

[0116] In addition, improving the crystallinity of silicon to polycrystalline or microcrystalline can reduce the size of the entire panel. It is preferable to perform the process in a region other than the region of the panel, but it is not limited to this. The crystallinity of the contact may be improved. The crystallinity can be improved by selectively applying a laser beam. For example, the peripheral circuit area, which is an area other than the pixels, can be selectively irradiated. Alternatively, the gate driver circuit, the source driver circuit, and the like may be irradiated with the laser light. Alternatively, the laser light may be irradiated only to a part of the source driver circuit ( For example, the laser light may be irradiated only on the area of ​​the analog switch. It is possible to improve the crystallization of silicon only in areas where the circuit needs to operate at high speed. Since there is little need for high-speed operation in the pixel area, there is no problem even if the crystallinity is not improved. The pixel circuit can be operated without any problem because the area for improving the crystallinity is small. The manufacturing process can also be shortened, improving throughput and reducing manufacturing costs. In addition, the number of manufacturing devices required is reduced, which reduces manufacturing costs. This can be done.

[0117] The capacitor 790 shown in FIG. 11 and FIG. 13 has the same semiconductor layer as the transistor 750. A lower electrode having a low resistance and a source electrode or a drain electrode are formed by processing a single film. and an upper electrode formed by processing the same conductive film. Between them, two insulating films are provided to cover the transistor 750. 90 is a laminated structure in which an insulating film functioning as a dielectric film is sandwiched between a pair of electrodes. .

[0118] In addition, a planarization insulating layer is formed on the transistor 750, the transistor 752, and the capacitor 790. A veneer 770 is provided.

[0119] A transistor 750 included in the pixel portion 702 and a transistor A transistor having a different structure from that of the transistor 752 may be used. A top-gate transistor is used in one side and a bottom-gate transistor is used in the other side. The source driver 704 may be replaced with a gate driver circuit section. It may be possible.

[0120] The signal line 710 is the same as the source and drain electrodes of the transistors 750 and 752. In this case, if a low-resistance material such as a material containing copper is used, the wiring This is preferable because it reduces signal delays caused by line resistance and enables display on a large screen.

[0121] The terminal portion 708 includes a connection electrode 760 , an anisotropic conductive film 780 , and an FPC 716 . The connection electrode 760 is electrically connected to a terminal of the FPC 716 via an anisotropic conductive film 780.

The pixel circuit 400 includes a transistor T The pixel circuit 400 includes a transistor Tr2, a capacitor C1, and a circuit 401. The wiring S1, the wiring S2, the wiring G1, and the wiring G2 are connected to each other.

[0158] The transistor Tr1 has a gate connected to the wiring G1 and one of the source and drain connected to the wiring S1. The other electrode of the transistor Tr2 is connected to one electrode of the capacitor C1. One of the source and drain is connected to the wiring G2, the other is connected to the wiring S2, and the other is connected to the other electrode of the capacitance C1. and circuit 401, respectively.

[0159] The circuit 401 is a circuit including at least one display element. Representative examples include light-emitting elements such as organic EL elements and LED elements, and liquid crystal Element, or MEMS (Micro Electro Mechanical System) ms) elements, etc. can be applied.

[0160] The node connecting the transistor Tr1 and the capacitor C1 is N1, and the transistor Tr2 and the circuit The node connecting to 401 is N2.

[0161] In the pixel circuit 400, the transistor Tr1 is turned off to set the potential of the node N1 to In addition, by turning off the transistor Tr2, the node N2 In addition, when the transistor Tr2 is in the off state, the potential of the transistor A predetermined potential is written to the node N1 via the transistor Tr1, Capacitive coupling allows the potential of node N2 to change in response to a change in the potential of node N1. can.

[0162] Here, an OS transistor is provided in one or both of the transistors Tr1 and Tr2. Therefore, the extremely low off-current can be used to The potential of the node N2 can be maintained for a long period of time. If the period is short (specifically, if the frame frequency is 30 Hz or higher), A transistor using a semiconductor such as silicon may also be used.

[0163] [Driving method example] Next, an example of a method of operating the pixel circuit 400 will be described with reference to FIG. 4B is a timing chart relating to the operation of the pixel circuit 400. For ease of understanding, we have not included various resistances such as wiring resistance, parasitic capacitances of transistors and wiring, The effects of the transistor threshold voltage, etc. are not taken into account.

[0164] In the operation shown in FIG. 15B, one frame period is divided into a period T1 and a period T2. T1 is a period during which a potential is written to node N2, and T2 is a period during which a potential is written to node N1. It is a period.

[0165] [Period T1] In the period T1, a potential that turns on the transistor is applied to both the wiring G1 and the wiring G2. In addition, the line S1 is connected to a fixed potential V ref The first data is supplied to the wiring S2. Voltage V w supplies.

[0166] The node N1 is connected to the line S1 via the transistor Tr1. ref is given In addition, the node N2 is supplied with a first data potential V w is given Therefore, the capacitance C1 has a potential difference V w -V ref is held.

[0167] [Period T2] Next, in a period T2, a potential is applied to the wiring G1 to turn on the transistor Tr1. A potential that turns off the transistor Tr2 is applied to the wiring G2. 2 Data potential V dataA predetermined constant potential is applied to the wiring S2, or a floating potential is applied to the wiring S3. It may also be used as a fingering.

[0168] The node N1 is supplied with a second data potential V data is given At this time, the second data potential V data Depending on the node The potential of N2 changes by a potential dV. That is, the circuit 401 has a first data potential Vw and The potential with the potential dV added is input. Note that in FIG. 15(B), dV is a positive value. Although the potential V is shown as a positive value, it may also be negative. data is the potential V r ef It may be lower.

[0169] Here, the potential dV is roughly determined by the capacitance value of the capacitor C1 and the capacitance value of the circuit 401. When the capacitance value of the capacitor C1 is sufficiently larger than the capacitance value of the circuit 401, the potential dV becomes the second Data potential V data The potential becomes close to

[0170] In this way, the pixel circuit 400 is a circuit including a display element that combines two types of data signals. Since the potential to be supplied to the line 401 can be generated, the gray scale correction can be performed within the pixel circuit 400. It will be possible to do so.

[0171] In addition, the pixel circuit 400 generates a potential that exceeds the maximum potential that can be supplied to the wirings S1 and S2. For example, when a light-emitting element is used, a high dynamic range ( In addition, when liquid crystal elements are used, overdriving is possible. It is possible to realize drive such as a spring.

[0172] [Example of application] [Example using liquid crystal element] The pixel circuit 400LC shown in FIG. 15C includes a circuit 401LC. has a liquid crystal element LC and a capacitance C2.

[0173] The liquid crystal element LC has one electrode connected to the node N2 and one electrode connected to the capacitance C2, and the other electrode connected to the Potential V com2 The other electrode of the capacitor C2 is connected to the wiring to which the potential V com1 Connect with the wiring given.

[0174] The capacitor C2 functions as a storage capacitor. If the capacitor C2 is not required, it can be omitted. Cut.

[0175] The pixel circuit 400LC can supply a high voltage to the liquid crystal element LC, so that, for example, Achieving high-speed display through overdrive operation and using liquid crystal materials with high drive voltage In addition, by supplying a correction signal to the wiring S1 or wiring S2, The gradation can also be corrected according to the temperature, the deterioration state of the liquid crystal element LC, and the like.

[0176] [Example using light-emitting element] The pixel circuit 400EL shown in FIG. 15D includes a circuit 401EL. includes a light-emitting element EL, a transistor Tr3, and a capacitor C2.

[0177] The transistor Tr3 has a gate connected to the node N2 and one electrode of the capacitor C2, and a source and One of the drains is a wiring to which a potential VH is applied, and the other is one of the electrodes of the light-emitting element EL. The capacitor C2 is connected to the other electrode at potential V com Connect with the given wiring The other electrode of the light-emitting element EL is at a potential V LConnect with the wiring given.

[0178] The transistor Tr3 has a function of controlling the current supplied to the light-emitting element EL. Capacitor C2 functions as a storage capacitor. Capacitor C2 can be omitted if not required.

[0179] In this example, the anode side of the light-emitting element EL is connected to the transistor Tr3. However, a transistor Tr3 may be connected to the cathode side. In that case, the potential V H And electricity Place V L The value of can be changed appropriately.

[0180] The pixel circuit 400EL emits light by applying a high potential to the gate of the transistor Tr3. Since a large current can be passed through the EL element, it is possible to realize, for example, HDR display. In addition, by supplying a correction signal to the wiring S1 or the wiring S2, It is also possible to correct the variations in the electrical characteristics of Tr3 and the light-emitting element EL.

[0187] This embodiment may be combined, at least in part, with other embodiments described in this specification. It can be implemented in combination.

[0188] (Embodiment 6) In this embodiment, a C This article explains the configuration of AC (Cloud-Aligned Composite)-OS. do.

[0189] CAC-OS is a type of metal oxide in which the elements constituting the metal oxide are 0.5 nm to 10 nm in diameter. Preferably, the material is unevenly distributed in a size range of 1 nm to 2 nm or less, or in the vicinity thereof. In the following, in the case of metal oxides, one or more metal elements are unevenly distributed. The region having the metal element has a size of 0.5 nm to 10 nm, preferably 1 nm or more. A state where particles are mixed in sizes of 2 nm or less or close to that size is called a mosaic or patch state. .

[0190] The metal oxide preferably contains at least indium. In addition to these, aluminum, gallium, yttrium, zinc, etc. are preferably contained. Lithium, Copper, Vanadium, Beryllium, Boron, Silicon, Titanium, Iron, Nickel, Gel Manium, zirconium, molybdenum, lanthanum, cerium, neodymium, hafnium, tantalum Contains one or more of the following: tantalum, tungsten, or magnesium. It's fine.

[0191] For example, CAC-OS in In-Ga-Zn oxide (In- Ga-Zn oxide (which may be specifically referred to as CAC-IGZO) is an indium oxide (Hereinafter, InO X1 (where X1 is a real number greater than 0), or indium zinc oxide (Hereinafter, In X2 Zinc Y2 O Z2 (X2, Y2, and Z2 are real numbers greater than 0.) ) and gallium oxide (GaO X3 (where X3 is a real number greater than 0), or Gallium zinc oxide (Ga X4 Zinc Y4 O Z4(X4, Y4, and Z4 must be greater than 0. The material is separated into a mosaic shape, and the mosaic shape is InO X1 , or In X2 Zinc Y2 O Z2 The structure in which the SiO2 is uniformly distributed in the film (hereafter referred to as "cladding") (also called udo-shaped).

[0192] In other words, CAC-OS is X3 The region where In is the main component and X2 Zinc Y2 O Z2 , or InO X1 A composite metal oxide having a structure in which a region in which In this specification, for example, the atomic ratio of In to the element M in the first region is The first region has an atomic ratio of In to the element M in the second region that is greater than the atomic ratio of In in the second region. The concentration of In is higher than in the region

[0193] Note that IGZO is a common name and refers to a compound made of In, Ga, Zn, and O. A typical example is InGaO3(ZnO). m1 (m1 is a natural number), or In (1 +x0) Ga (1-x0) O3(ZnO) m0 (-1≦x0≦1, m0 is an arbitrary number) Examples of such crystalline compounds include those that are

[0194] The crystalline compound has a single crystal structure, a polycrystalline structure, or a CAAC structure. The CAAC structure is a structure in which multiple IGZO nanocrystals have a c-axis orientation and are aligned in the ab plane. is a non-oriented connected crystal structure.

[0195] On the other hand, CAC-OS is a material structure of metal oxide. In a material composition containing a, Zn, and O, nanoparticles with Ga as the main component were observed in some areas. The regions where the In is mainly contained are observed as nanoparticles, and the regions where the In is mainly contained as nanoparticles are observed. Therefore, in CAC-OS, The crystal structure is a secondary factor.

[0196] Note that CAC-OS does not include a laminated structure of two or more films with different compositions. For example, a structure consisting of two layers, one containing In as the main component and the other containing Ga as the main component, Not at all.

[0197] In addition, GaO X3 The region where In is the main component and X2 Zinc Y2 O Z2 , or InO X1 but In some cases, it is difficult to observe the region that is the main component as a clear boundary.

[0198] Instead of gallium, aluminum, yttrium, copper, vanadium, and beryllium are used. Aluminum, boron, silicon, titanium, iron, nickel, germanium, zirconium, molybdenum lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, or magnesium If one or more selected from the group consisting of uranium, sodium, etc. are included, CAC-OS will The region observed is a nanoparticle of the metal element as the main component, and the other region is a nanoparticle of In as the main component. The regions observed as particles are randomly distributed in a mosaic pattern. cormorant.

[0199] CAC-OS can be formed, for example, by a sputtering method without heating the substrate. In addition, when the CAC-OS is formed by a sputtering method, the following deposition gas is used: Any one selected from an inert gas (typically argon), oxygen gas, and nitrogen gas. In addition, the flow rate of oxygen gas relative to the total flow rate of deposition gas during deposition may be The lower the ratio, the more preferable. For example, the flow rate ratio of oxygen gas is set to 0% or more and less than 30%, preferably 0%. It is preferable to set the ratio to 10% or less.

[0200] CAC-OS is a method for measuring X-ray diffraction (XRD). When measured using the out-of-plane θ / 2θ scan, In other words, no clear peaks are observed in the X-ray diffraction measurement. It can be seen that no orientation in the ab plane direction or the c-axis direction is observed in the fixed region.

[0201] In addition, the CAC-OS uses an electron beam with a probe diameter of 1 nm (also called a nanobeam electron beam). In the electron diffraction pattern obtained by irradiating the sample with electrons, a ring-shaped area of ​​high brightness (ring The electron diffraction pattern shows that the ring region is dominated by a single bright spot. The crystal structure of CAC-OS has no orientation in the planar direction and cross-sectional direction. It can be seen that it has a c (nano-crystal) structure.

[0202] For example, in the CAC-OS of In-Ga-Zn oxide, the energy dispersive X Energy Dispersive X-ray spectroscopy (EDX) The EDX mapping obtained using scopy revealed that GaO X3 The area where is the main component And, In X2 Zinc Y2 O Z2 , or InOX1 The areas where the main component is It can be confirmed that the compound has the structure shown in FIG.

[0203] CAC-OS has a structure different from that of IGZO compounds in which metal elements are uniformly distributed. It has different properties from GZO compounds. That is, CAC-OS is GaO X3 The main components are and the region where In X2 Zinc Y2 O Z2 , or InO X1 The region where is the main component and The phase is separated into two layers, and the regions each containing one element as a main component are arranged in a mosaic pattern.

[0204] Here, In X2 Zinc Y2 O Z2 , or InO X1 The area where GaO is the main component X3 This region has a higher electrical conductivity than the region where In is the main component. X2 Zinc Y 2O Z2 , or InO X1 The carriers flow through the area where the main component is the metal oxide. Therefore, the In X2 Zinc Y2 O Z2 , or InO X1 The regions where the main component is distributed in a cloud-like shape in the metal oxide provide high field effect mobility. degree (μ) can be achieved.

[0205] On the other hand, GaO X3 The region where the main components are In X2 Zinc Y2 O Z2 , or InO X This region has higher insulating properties than the region where GaO X3etc. The main component is distributed in the metal oxide, which suppresses leakage current and provides good switching performance. This allows for switching operations.

[0206] Therefore, when CAC-OS is used in a semiconductor device, GaO X3 Insulation due to Sex and In X2 Zinc Y2 O Z2 , or InO X1 The conductivity caused by the This results in a high on-state current (I on ), and high field-effect mobility (μ) can be done.

[0207] In addition, semiconductor devices using CAC-OS have high reliability. This is ideal for a variety of semiconductor devices including displays.

[0208] This embodiment mode can be implemented in appropriate combination with other embodiment modes.

[0209] In this specification, unless otherwise specified, the on-state current is the current that flows when a transistor is in the on-state. The drain current when the transistor is in the on state (sometimes abbreviated as on) is In the case of an n-channel transistor, the voltage between the gate and source (V G ) is the threshold voltage Pressure (V th ) above, for p-channel transistors, V G V th The following states For example, the on-current of an n-channel transistor is V G V th When the above The on-current of a transistor is determined by the voltage between the drain and source (V D ) may be dependent on

[0210] Unless otherwise specified, in this specification, the off-state current refers to the current flowing when a transistor is in an off state.

In the case of V G V th For example, in an n-channel transistor, The off-state current of the G V th The drain current of a transistor is lower than The off-state current is V G Therefore, the off-state current of a transistor may depend on - 21 A means that the off-state current of the transistor is less than 10 -21 V less than A G The value of It may be said that it exists.

[0211] The off-state current of the transistor is V D In this specification, Unless otherwise specified, the V D The absolute value of is 0.1V, 0.8V, 1V, 1.2V, Available in 1.8V, 2.5V, 3V, 3.3V, 10V, 12V, 16V, or 20V It may also refer to a transistor's current. V to be D In some cases, it represents the off-state current at

[0212] Voltage refers to the potential difference between two points, and potential refers to the electrostatic field at a certain point. This refers to the electrostatic energy (electrical potential energy) possessed by a unit charge in a particle. Generally, the potential difference between a potential at a certain point and a reference potential (for example, ground potential) This is simply called potential or voltage, and potential and voltage are often used synonymously. Therefore, in this specification, unless otherwise specified, potential may be read as voltage. In this specification, voltage may be read as potential.

[0213] In the present specification, when it is explicitly stated that X and Y are connected, The case where X and Y are electrically connected and the case where X and Y are directly connected are It is assumed that the same is disclosed in the specification, etc.

[0214] Here, X and Y are objects (e.g., devices, elements, circuits, wiring, electrodes, terminals, conductive films, layer, etc.).
