[0063] 《Sign part》 The sign portion 104b is provided on the touch panel 500TP. 4a, which is composed of a plurality of markers Pt_1 to Pt_h that can be recognized by the Here, h is a natural number equal to or greater than 1. The above-mentioned multiple markers Pt_1 to Pt_h are arranged The shape of the object varies depending on the location, and the detector element 104a detects the difference in shape. In FIG. 4(A), a barcode-shaped marker Pt_h1 and a marker Pt_h2 are placed at different positions. In addition, FIG. 7(A) shows an example in which the marker Pt_h1 and the marker Pt_h2 are present. In Fig. 7(B), letters are used as the markers Pt_h1 and Pt_h2. Here is an example: Note that h1 and h2 are natural numbers between 1 and h, and h1 and h2 are different. In addition, the marker Pt may be any other marker that can be detected by the detection element 104a, regardless of shape. For example, the regions with different magnetic fields may be labeled with Pt, and the difference in magnetic properties may be measured. Alternatively, for example, a region having a different electric field may be targeted. Alternatively, the detection element 104a may detect the difference in electrical property by using the identification Pt.

[0064] The sign portion 104b may be provided at any position on the touch panel 500TP. 04b may be provided on the surface of the touch panel 500TP facing the touch sensor 600, or The touch panel 500TP may be provided on the opposite side to the touch sensor 600 side. FIG. 8A is a top view of the information processing device 100 having the marker portion 104b on the opposite surface, and FIG. FIG. 8B shows the information processing device from the opposite side to FIG. 8A. 8(B) is a bottom view of the device 100. FIG. 8(C) is a bottom view of the device 100. 8(B) is a cross-sectional view corresponding to the dashed line X1-X2 of the information processing device 100 shown in FIG. In the touch panel 500TP, the touch sensor 600 is provided on the surface shown in FIG. Therefore, the sign portion 104b is provided on the surface opposite to the touch sensor 600 side. As shown in FIG. 8, the sign portion 104b is provided on the surface opposite to the touch sensor 600 side. This makes it possible to enlarge the area 101. For example, the display unit 500 and the touch sensor 600 may be attached to each other. The touch sensor 600 may be provided on a surface where the touch sensor 600 is fixed, or on the inside of the display unit 500 or the touch sensor 600. The recognition unit 104b may be provided on a side surface of the touch panel 500TP. FIG. 9A is a perspective view of the information processing device 100 having the indicator portion 104b on the side of the information processing device 100. As shown in FIG. 9B, the sign portion 104b is attached to the side of the touch panel 500TP. By providing this, the area 101 can be made wider.

[0065] The marker Pt can have various shapes. The shape of the marker Pt is determined by the sensing element 104a. Anything that can be detected is acceptable. In addition, the marker Pt may have different shapes. For example, a one-dimensional code such as a barcode, a QR code (registered trademark), etc. You can use two-dimensional codes such as the above. You can also use numbers, letters, symbols, shapes, colors, etc. It can be used as a label Pt.

[0066] The multiple signs Pt having different shapes are provided on the sign section 104b of the touch panel 500TP. The touch panel 500TP is wound up on the winding section 106. At that time, the relative positional relationship between the sensing element 104a and the touch panel 500TP changes. Therefore, the marker Pt detected by the detection element 104a also changes. The state of the touch panel 500TP, specifically the touch panel 5 It is possible to obtain information on the area wound around the winding section 106 of the 00TP.

[0067] For example, as shown in FIG. 4A, markers Pt_h1 and Pt_h2 are arranged in the marker section 104b. In this case, when the detection element 104a detects the label Pt_h1, the information processing device 100 performs the process shown in FIG. In the state shown in FIG. 1B, when the detector element 104a detects the marker Pt_h2, the information processing The device 100 can be seen in the state shown in FIG.

[0068] In addition, for example, the driving unit 103 or the calculation unit 110 determines which type of sign Pt is displayed on the touch panel. By storing data on where on the 500TP the detector element 10 is located, The type of the sign Pt detected by 4a is wound up in the winding section 106 of the touch panel 500TP. The area covered can be calculated.

[0069] In addition, when the touch panel 500TP is wound around the winding section 106, the sensing element 104a The first information regarding the state of the touch panel 500TP is obtained based on the number of signs Pt detected by the In this case, the shapes of the multiple markers Pt may be the same. For example, When detecting the labeled Pt in order, there is a state where h1 labeled Pt is detected and a state where h2 labeled Pt is detected. Therefore, the number of detected signs Pt is related to the state of the touch panel 500TP. In this case, the sensing element 104a detects that the touch panel 500TP is wound up. It is determined whether the paper is being wound around the winding section 106 or unwound from the winding section 106. For example, when a camera is used for the detector element 104a, Depending on the direction in which the sign Pt moves, the touch panel 500TP is wound up on the winding section 106. It is possible to determine whether the tape is being wound or unwound from the winding portion 106.

[0070] <Detection unit configuration example 2> The detection unit 104 in this configuration example detects the degree of rotation of the winding unit 106 relative to the housing 105. The degree of rotation of the winding part 106 relative to the housing 105 is determined by the amount of winding. The total number of rotations or the total angle of rotation of the scraper 106 relative to the housing, or the cumulative total For example, the degree of rotation of the winding portion 106 relative to the housing 105 is Based on the state where 00TP is not wound on the winding section 106, This refers to the total number of rotations or the total angle of rotation. When the number of rotations is 106, the sum of all the rotations is the degree of rotation. If the rotation in the direction of winding the Chipanel 500TP is positive, the rotation in the direction of unrolling is negative. The calculation is based on the number of units. Note that the positive and negative signs may be interchanged.

[0071] The detection unit 104 is capable of detecting the degree of rotation of the winding unit 106 relative to the housing 105. For example, a potentiometer capable of detecting rotation may be used. In this case, a potentiometer that can detect multiple rotations can be used. It is preferable to use

[0072] In this configuration example, the degree of rotation of the winding unit 106 relative to the housing 105 obtained by the detection unit 104 is Information regarding the alignment is supplied to the driving unit 103 or the calculation unit 110.

[0073] Further, the driving unit 103 controls the touch sensor based on the first information supplied from the detection unit 104. Alternatively, the first information provided by the detection unit 104 and the winding unit 10 are used to drive the sensor 600. Based on information such as the diameter of touch panel 506 and the thickness of touch panel 500TP, The area wound around the winding section 106 of the touch panel 500TP is calculated. The touch sensor 600 provided in the area not wound around the take-up portion 106 is driven. Alternatively, the detection unit 104 supplies the first information to the calculation unit 110, and the calculation unit 110 calculates the above The first information and information such as the diameter of the winding part 106 and the thickness of the touch panel 500TP The area of ​​the touch panel wound around the winding unit 106 is calculated based on the calculated area. The second information is supplied to the driving unit 103, and the driving unit 103 performs the following operation based on the second information: The touch panel 500TP is provided in an area that is not wound around the winding section 106. The touch sensor 600 is driven.

[0074] In this specification, the first information or the second information relating to the state of the touch panel 500TP The information refers to information related to the state of the touch panel 500TP in general. The second information, when combined with other information, indicates the status of the Touch Panel 500TP. By combining it with other information, the touch panel 5 The information that can tell the state of 00TP is, for example, the detection element shown in the configuration example 1 of the detection unit. The type of marker Pt detected by the detection element 104a is shown in FIG. What kind of sign Pt is present in what position of the sign section on the touch panel 500TP? By comparing the data on the condition of the Touch Panel 500TP and the specific Specifically, the area of ​​the touch panel 500TP wound around the winding section 106 is calculated. is possible.

[0075] The first information or the second information relating to the state of the touch panel 500TP is It is directly related to the operation of the touch sensor 600 which is operated based on the state of the touch panel 500TP. For example, as described later in the third embodiment, it is possible to determine which control lines are to be supplied with control signals and which control lines are to be supplied with control signals. Information such as which signal line to use for detection signals and which The first information or the second information may be information such as whether or not to use the detection signal of the signal line. When the information of 2 is sent from the detection unit 104 to the driving unit 103, it is combined with other information and The touch sensor 600 is limited and driven without calculating the state of the touch panel 500TP. It is possible.

[0076] <<Operation of Information Processing Device>> The following describes the information processing when the touch panel 500TP is partially wound around the winding section 106. The operation of the management device 100 will now be described.

[0077] (First step) A rotation mechanism provided in the housing 105 rotates the winding part 106 relative to the housing 105. Then, the touch panel 500TP is partially wound around the winding section 106 (see FIG. 4(B)). Here, the area 500TP_2 shown in FIG. 4(B) and (C) is wound up by the winding section 106. not present.

[0078] (Second step) The detection unit 104 determines the state of the touch panel. Specifically, the detection unit 104 obtains first information related to the state of the touch panel 500TP. The first information is obtained from the detection unit 106. For example, in the above example 1 of the detector, as shown in FIG. Then, the detector element 104a detects the marker Pt_h1. The information about the marker Pt_h1 is , the first information relating to the state of the touch panel 500TP, specifically, the touch panel 500T This is the first information relating to the area of ​​P wound up on the winding unit 106.

[0079] (Third step) The detection unit 104 detects the first information related to the state of the touch panel 500TP obtained in the second step. to the driving unit 103. Specifically, the detection unit 104 detects the winding of the touch panel 500TP. The take-up section 106 is provided with first information relating to the wound area.

[0080] Alternatively, the detection unit 104 supplies the first information relating to the state of the touch panel to the calculation unit 110. The calculation unit 110 may calculate second information relating to the state of the touch panel based on the first information. After the calculation, the detection unit 104 supplies the second information to the driving unit. The first information relating to the area of ​​the flannel 500TP wound around the winding unit 106 is input to the calculation unit 110. The calculation unit 110 supplies the touch panel 500TP with the winding amount based on the first information. After calculating second information relating to the area wound around the winding section 106, the second information is sent to the driving section. Supply.

[0081] (Fourth step) The driving unit 103 controls the touch sensor 60 based on the first information or the second information. Specifically, the driving unit 103 drives a part of the touch panel 500TP. The touch sensor 600 provided in the area not wound around the unit 106 is driven. The driving unit 103 is provided in the area of ​​the touch panel 500TP that is wound around the winding unit 106. For example, the touch sensor 600 in the area 500TP_ 2, and drives the touch sensor 600 provided in the area 500TP_1. As mentioned above, the sensor 600 is not driven. 13 is a diagram showing a state in which the touch panel 500TP shown in FIG.

[0082] In addition, the entire area of ​​the touch panel 500TP that is not wound around the winding section 106 is driven. In other words, the touch panel 500TP is not necessarily wound around the winding section 106. In the region where the touch sensor 600 is driven, the driving range of the touch sensor 600 may be adjusted. In a configuration in which the mounting portion 106 is provided on the housing 105, The area stored in 105 is wound up in a winding section 106 of the touch panel 500TP. For example, when the housing 105 is provided with rollers 108, The touch panel 500 is rotated so as to avoid the area where the rollers 108 and the like come into contact with the touch panel. In the area of ​​the TP that is not wound around the winding section 106, the touch sensor 600 is driven. The driving unit 103 may determine a range in which the touch panel 500TP is moved. The touch sensor 600 provided in the uncontained area is driven to form the touch panel 500T. The touch sensor 600 provided in the area accommodated in the housing 105 of P does not need to be driven. For example, when the touch sensor 600 provided in the area 500TP_4 shown in FIG. The touch sensor 600 in the region 500TP_3 is not driven. 103 is a driving area of ​​the touch sensor 600 based on the detection element 104a. For example, the area 500TP_6 shown in FIG. 6(D) may be provided with The touch sensor 600 is driven, and the touch sensor 600 provided in the area 500TP_5 is driven. It doesn't move.

[0083] The method in which the driving unit 103 drives a part of the touch sensor 600 will be described in detail in the third embodiment. explain.

[0084] In addition, a touch panel 500TP is provided in an area that is not wound around the winding section 106. The display unit 500 is driven, and the area wound around the winding unit 106 of the touch panel 500TP is The display unit 500 provided in the display area does not need to be driven.

[0085] The touch panel 500TP supplied from the detection unit 104 is wound up by the winding unit 106. The display area of ​​the display unit 500 can be restricted based on the first information relating to the area. Alternatively, the touch panel 500TP supplied from the calculation unit 110 is wound up on the winding unit 106. The display area of ​​the display unit 500 can be restricted based on the second information related to the restricted area. For example, a region of the touch panel 500TP that is not wound around the winding section 106 may be provided with a Only the display unit 500 is driven. Only the display unit 500 provided in the area where the display is not stored is driven.

[0086] When limiting the area in which the display unit 500 is driven, the winding unit 10 of the touch panel 500TP In the areas not wrapped around the 6, the image may be transformed so that the entire image is visible. In addition, a region of the touch panel 500TP that is not wound around the winding section 106 is provided with a The image does not have to be displayed on the entire display area. The area may be changed. The orientation of the image may also be changed. For example, For maximum visibility, the image may be rotated 90 degrees. For example, the original image is displayed horizontally. When the screen is longer than the height, but the display area is shorter than the width, rotating the image 90 degrees reduces the image size. The image can be displayed large. In addition, the orientation of the image can be changed by adjusting the touch panel orientation using MEMS ( It detects the movement of objects using sensors such as microelectromechanical systems and processes the information in a predetermined manner. The image may be transformed so that the top of the processing device 100 and the top of the image are aligned. When converting an image so that the body is visible, limit the viewing area to match the aspect ratio of the original image. It is preferable to limit the display area to a number of pixels and an area that allows easy image conversion. may be limited.

[0087] In addition, when the display area is changed, the area for driving the touch sensor 600 is adjusted to match the display area. May be changed.

[0111] Overall Composition The touch panel 500TP described in this embodiment includes a touch sensor 600 or a display unit 5 00.

[0112] An example of a method for producing a laminate that can be applied to the production of the touch panel 500TP is as follows: This will be explained in detail in the fourth to sixth embodiments.

Alternatively, when the object to be sensed is brought close to the second electrode, a capacitance is generated between the object and the second electrode.

[0119] When an AC or pulse voltage is applied to the control line, the signal line However, if a detection object approaches the intersection and capacitance occurs, the current flows in a counter-inverted manner. Since it is affected by the electrostatic capacitance in addition to the mutual capacitance, the value of the current flowing through the signal line changes depending on the proximity of the object to be detected. The current flowing through the signal line is used as the detection signal. In addition, when a plurality of control lines and signal lines are provided, the voltage can be applied to a plurality of control lines. When a current is supplied to the signal lines in sequence, the current flows through the signal lines in sequence. Based on the amount of change and the timing of the current flow, the position of the intersection where the object to be detected is close is detected. Therefore, the position of the object to be detected that is in proximity to or in contact with the touch sensor 600 can be detected. It is possible to detect.

[0193] The control line is supplied with a control signal and extends in the direction indicated by the arrow R in the figure.

[0194] The signal line extends in the direction indicated by the arrow C in the figure and supplies a detection signal.

[0195] A flexible substrate 610 supports the control and signal lines.

[0196] The control lines CL(1) to CL(m) are connected to a wiring section 111 made up of a plurality of wires and a flexible The signal line ML(1 ) to the signal line ML(n), the wiring section 112 made up of a plurality of wirings and the flexible substrate FP It is electrically connected to the output section 103D via C1.

A wiring portion 111 may be provided.

[0197] The touch panel 500TP and the winding part 106 are wound in the direction of the side of the area 107 of the touch sensor. For example, the edge of the touch panel 500TP and the edge of the touch sensor 600 are aligned with each other. If the area 107 is the same as the edge of the touch panel 500TP, the area 107 will The touch panel 500TP is fixed to the winding section 106. Even if it does not coincide with the edge of the sensor 600, as shown in FIG. 13(A), it is possible to detect the outside of the region 107. In a certain region 107_2, the touch panel 500TP is fixed to the winding portion 106. The touch panel 500TP is wound around the winding section 106 in the direction indicated by the arrow C. become.

[0198] In this configuration example, the direction in which the touch panel 500TP is wound by the winding unit 106 is controlled by Intersects with the direction in which the line extends.

[0199] The touch panel 500TP is wound around the winding section 106 in a direction parallel to the extension of the control wire. It is preferable that the direction perpendicular to the direction of the touch panel 500 is intersected. The control line is partially provided in the area wound around the winding section 106 of the TP. This is because, in the above configuration, the boundary between the wound area and the unwound area is This is because the control lines are parallel to each other.

[0200] In addition, the touch sensor 600 of one embodiment of the present invention has first electrodes C1(1) to C The first electrode C2(m) and the second electrode C2(1) to second electrode C2(n).

[0201] The first electrode C1(i) ​​is electrically connected to one control line CL(i). It is a natural number up to and including m.

[0202] The second electrode C2(j) is electrically connected to one signal line ML(j) and is connected to the first electrode C 1(1) to the first electrode C1(m), and j is 1 to n. is a natural number.

[0205] The signal lines ML(1) to ML(n) can be supplied with detection signals.

[0206] The control signal supplied by the control line is detected by the signal line via the capacitance formed between the signal line and the control line. This is detected as a detection signal.

[0207] When the signal line and the control line are formed using a conductive film formed in the same process, At the intersection of the signal lines, one of the wirings is separated. Then, an insulating film is applied to the intersection. and electrically connect one of the wirings separated by another conductive film with an insulating film sandwiched between the other wiring. Connect to the target.

[0208] For example, the control line CL(i) is formed separately and separated using a conductive film BR(i,j). The control line CL(i) is electrically connected. Note that the conductive film BR(i,j) and the signal line ML(j) An insulating film 611 is provided at the intersection (see FIG. 14(A)).

The intensity of light incident on the signal line ML(j) or control line CL(i) The intensity of the reflected light can be weakened. The light-shielding layer BM can have an opening. This is possible (see Figure 14(C)).

[0210] The insulating film 611 has an opening that reaches the control line CL(i). Thus, the control line CL(i) is electrically connected to the conductive film BR(i,j).

[0211] Specifically, the control line CL(i) and the signal line ML(j) are made of a conductive film formed in the same process. The control line CL(i) is separated from the signal line ML(j) at the intersection. The separated control lines CL(i) are electrically connected by a conductive film BR(i,j).

[0212] Also, a first electrode C1(i) ​​electrically connected to the control line CL(i) may be provided. The first electrodes C1(i) ​​are connected to a finger or a stylus tip that is in close proximity to or in contact with the touch sensor 600. This makes it easier to detect objects to be detected, such as a cigarette.

[0213] In addition, a second electrode C2(j) that is electrically connected to the signal line ML(j) may be provided. The second electrode C2(j) is a contact point for a finger or a stylus tip that is in close proximity to or in contact with the touch sensor 600. This makes it easier to detect objects to be detected, such as a cigarette.

[0214] For example, rectangular electrodes can be used for the first electrode C1(i) ​​and the second electrode C2(j). (See FIG. 14A). Note that when a light-transmitting conductive film is used, A touch sensor may be provided.

[0215] For example, the first electrode C1(i) ​​and the second electrode C2(i) are rectangular and have openings formed in a mesh pattern. and a second electrode C2(j) can be used (see FIG. 14(B) or FIG. 14(C)). ) In addition, when a metal film or the like having openings is used, the light-transmitting conductive film is used. This allows the electrical resistance to be reduced compared to conventional methods. It is possible to provide a touch sensor of a small size, and to provide detection information regardless of the size. For example, the size of the device can be used for handheld applications, and it can be used for electronic devices. To provide touch sensors of various sizes, including a size that can be used on a blackboard can be done.

[0223] Alternatively, a conductive polymer can be used for the conductive film.

[0224] <<Method of Driving Touch Sensor in Configuration Example 1>> In the following, in the touch panel 500TP of the first configuration example, the driving unit 103 drives the touch sensor 6 1 shows a method for driving a part of the touch panel 500TP. When the touch panel was partially wound up in the winding section of the 06, it was not wound up in the winding section of the touch panel 500TP. The touch sensor 600 provided in the touch panel 500TP is driven. Regarding a method for not driving the touch sensor 600 provided in the wound area, FIG. Explain using (A) etc.

[0225] The detection unit 104 supplies first information relating to the state of the touch panel 500TP to the drive unit. Specifically, the detection unit 104 detects that the touch panel 500TP is wound around a winding unit 106. The first information relating to the taken area is provided to the driver 103 .

[0226] As shown in FIG. 15A, the detection unit 104 detects the state of the touch panel 500TP. The first information is supplied to the calculation unit 110, and the calculation unit 110 calculates a touch panel based on the first information. The calculation unit 110 may be configured to calculate second information related to the state of the panel 500TP. The second information on the state of the touch panel 500TP calculated by the above is supplied to the driving unit 103. Specifically, the detection unit 104 detects that the touch panel 500TP is wound around a winding unit 106. The first information relating to the extracted area is supplied to the calculation unit 110, which calculates the first Based on the information, a second The information calculated by the calculation unit 110 is the winding part of the touch panel 500TP. Second information relating to the wound area at 106 is provided to the driver 103 .

[0227] The control unit 103C of the driving unit 103 supplies a control signal. For example, the control unit 103C A signal is supplied to each control line in sequence. Alternatively, the output unit 103D can be separated. A plurality of signals modulated by the above-mentioned is supplied to a plurality of control lines at the same time.

[0228] However, the touch panel 500TP supplied to the driving unit 103 is wound up by the winding unit 106. Based on the first information or the second information of the area, A control signal is supplied to a control line provided in an area not wound around the touch panel 106. A control signal is sent to the control line provided in the area wound around the winding section 106 of the 500TP. For example, in the area wound around the winding section 106 of the touch panel 500TP, When the control lines CL(1) to CL(k1) are provided, the control lines CL(k1+1) supplying control signals to the control lines CL(1) through CL(k1); Here, k1 is a natural number between 1 and m-1. If the switch panel 500TP is provided in the area wound around the winding section 106, No control signal is supplied to the control line. In addition, all of the control lines CL(k1+1) to CL(m) It is not necessary to supply a control signal to the For example, when the roller 108 or the like comes into contact with the control line CL(i), There is no need to provide a control signal to CL(i).

[0229] When a detected object such as a finger or a stylus pen is electrically connected to the control line CL(i1) or the control line CL(i1), When the object to be detected approaches a conductive film such as the first electrode C1(i1) that is electrically connected to the object, The capacitance between the electrodes changes. Here, i1 is a natural number between (k1+1) and m. Also, , the signal line ML(j) and the second electrode C2(j) electrically connected to the signal line ML(j), etc. When the object to be detected approaches the conductive film, the capacitance between the object to be detected and the conductive film also changes. Then, the detection signal changes based on the change in the capacitance.

[0230] The output section 103D receives a detection signal. The touch sensor 600 changes the detection signal by, for example, The proximity or contact of the object to be detected can be detected based on whether the change exceeds a threshold value. The above operation can be rephrased as touch detection.

[0231] By using the above driving method, the touch sensor 600 included in the information processing device 100 can be prevented from being misdetected. In addition, the number of control lines that supply control signals can be reduced. Therefore, power consumption can be reduced.

[0232] <Modification of Configuration Example 1 of Touch Sensor> The detection signal is supplied to the output section through the signal line and the second electrode. Since the touch panel 500TP is wound from the side closest to the output section, the detection signal is , the signal lines and the like provided in the area wound around the winding section 106 of the touch panel 500TP and through the second electrode.

[0233] On the other hand, the touch sensor 600 has a configuration in which the wiring portion 112 is routed as shown in FIG. In this way, the detection signal may be wound around the winding section 106 of the touch panel 500TP. The electric current is supplied to output section 103D without passing through a second electrode provided in the removed region.

[0234] Also, as shown in FIG. 17(A), the driving unit 103 is arranged in a direction different from the direction in which the winding unit 106 is arranged. In this way, the detection signal is transmitted to the touch panel 500TP. The signal line and the second electrode provided in the area wound around the winding section 106 are not passed through. In the configuration of FIG. 17(A), for example, the drive unit is provided in the handle, etc. It can be set up in.

[0235] <Touch sensor configuration example 2> The second configuration example is different from the first configuration example in the positional relationship between the control line and the signal line and the winding unit 106. The second example will be described with reference to FIG.

[0236] FIG. 12B illustrates a top view and a block diagram of the touch sensor 600 of the second configuration example. In addition, in FIG. 12B, for the sake of explanation, the touch sensor 600 is shown in a state where it is spread out in a flat shape. 12B, a part of the touch panel 500TP is wound around the winding section 106. The driving method in the removed state may be described.

[0237] The driving unit 103 includes a control unit 103C and an output unit 103D. The control unit 103C outputs a control signal The output unit 103D is supplied with a detection signal. This includes information about the position of the touch sensor where a detectable object such as a pencil is approaching or in contact with the touch sensor.

For example, the edge of the touch panel 500TP and the edge of the touch sensor 600 are aligned with each other. If the area 107 is an edge of the touch panel 500TP, the area 107 is P is fixed to the winding part 106. In addition, the end of the touch panel 500TP is a touch sensor Even if it does not coincide with the edge of 600, as shown in FIG. 13B, the area outside the area 107 In the region 107_2, the touch panel 500TP is fixed to the winding portion 106. The direction in which the switch panel 500TP is wound up by the winding section 106 is the direction shown by the arrow C. .

[0243] In this configuration example, the touch panel 500TP is wound around the winding unit 106 in the direction parallel to the signal line. intersects with the direction in which it extends.

[0244] The touch panel 500TP is wound around the winding section 106 in a direction parallel to the extension of the signal lines. With the above configuration, a part of the signal line is wound up, and the direction perpendicular to the winding direction is preferably intersected. The signal line is in an area wound around the winding portion 106, and another part of the signal line is wound around the winding portion 106. It becomes difficult for the wire to exist in an area that is not wound.

[0245] <<Method of Driving Touch Sensor in Configuration Example 2>> In the following, in the touch panel 500TP of the second configuration example, the driving unit 103 drives the touch sensor 6 Specifically, the touch panel 500TP drives a part of the winding section 100. When the touch panel was partially wound up in the winding section of the 06, it was not wound up in the winding section of the touch panel 500TP. The touch sensor 600 provided in the touch panel 500TP is driven. Regarding a method for not driving the touch sensor 600 provided in the wound area, FIG. (B) etc. will be used for explanation.

[0246] The detection unit 104 provides the first information related to the state of the touch panel 500TP to the drive unit 103. Specifically, the detection unit 104 detects the winding unit 106 of the touch panel 500TP. The first information relating to the area wound on the web is provided to the driving unit 103.

[0247] As shown in FIG. 15B, the detection unit 104 detects the state of the touch panel 500TP. The first information is supplied to the calculation unit 110, and the calculation unit 110 calculates a touch panel based on the first information. The calculation unit 110 may be configured to calculate second information related to the state of the panel 500TP. The second information on the state of the touch panel 500TP calculated by the above is supplied to the driving unit 103. Specifically, the detection unit 104 detects that the touch panel 500TP is wound around a winding unit 106. The first information relating to the extracted area is supplied to the calculation unit 110, which calculates the first Based on the information, a second The information calculated by the calculation unit 110 is the winding part of the touch panel 500TP. Second information relating to the wound area at 106 is provided to the driver 103 .

[0248] The control unit 103C of the drive unit 103 supplies control signals to the control lines CL(1) to CL(m). For example, the control unit 103C supplies a control signal to each control line CL(i) in turn. Alternatively, the output unit 103D may output a plurality of modulated signals in a manner that allows the signals to be separated. The control lines CL(i) are supplied at the same time.

[0249] When a detected object such as a finger or a stylus pen electrically connects to the control line CL(i) or When the object to be detected approaches a conductive film such as the connected first electrode C1(i), a static The capacitance of the signal line ML(j) and the second When the object to be sensed approaches the conductive film of the electrode C2(j) or the like, the object to be sensed and these conductors are The capacitance between the conductive membranes also changes. The detection signal changes based on the change in capacitance. do.

[0250] The output section 103D receives a detection signal. The output unit 103D detects, for example, a change in the detection signal. The proximity of the detection object to the conductive film can be detected based on whether the threshold value is exceeded. The touch sensor 600 detects a position on the touch sensor 600 where a detected object is in proximity to or in contact with the touch sensor 600. You can find out the location.

[0251] However, the area wound up on the winding part of the touch panel 500TP supplied from the detection part Based on the first information relating to the above, the touch panel 500TP is wound up on the winding unit 106. The touch panel uses the detection information provided by the signal line ML(j) in the area where the touch panel is not From the signal line ML(j) provided in the area wound around the winding section 106 of the 500TP For example, the winding section 106 of the touch panel 500TP does not use the detection information supplied. When the signal lines ML(1) to ML(k2) are provided in the area wound around the Using the detection information supplied from lines ML(k2+1) to ML(n), ML(k2) does not use the detection information provided by ML(k1) or ML(k2), where k1 is 1 to n-1. It should be noted that all the signals supplied from the signal lines ML(k2+1) to ML(n) are natural numbers. It is not necessary to use the detection information, but it is possible to select it as necessary. For example, when the roller 108 or the like comes into contact with the signal line ML(k2+1), the signal There is no need to use the detection information for Line ML(k2+1).

[0252] By using the above driving method, the touch sensor 600 included in the information processing device 100 can be prevented from being misdetected. Knowledge can be prevented.

[0253] <Modification of Configuration Example 2 of Touch Sensor> In the configuration of FIG. 12B, a control signal passes through the control line and the first electrode, and touch detection is performed. In the configuration of FIG. 12B, the touch panel 500TP is provided to a control Since the wire is wound from the side closest to the touch panel, the control signal supplied from the control unit 103C is The control wire and the first wire are provided in the area wound around the winding section 106 of the flannel 500TP. through the electrodes.

[0254] On the other hand, the touch sensor 600 has a configuration in which the wiring portion 111 is routed as shown in FIG. As a result, the control signal may be sent to the winding section 106 of the touch panel 500TP. The electric current is supplied to the area where touch detection is performed without passing through the first electrode provided in the removed area. do.

[0255] In addition, the touch sensor 600 has a driving unit and a winding unit, as shown in FIG. The touch panel may be configured so that the control signal is provided in a direction different from the direction of the touch panel. Control wire and first electrode provided in the area wound on the 500TP winding section 106 In the configuration of FIG. 17B, for example, The drive unit 103 can be provided in the handle or the like.

[0256] <Touch sensor configuration example 3> Another structure of the touch sensor according to one embodiment of the present invention will be described.

[0257] The touch sensor described herein provides control signals modulated differently for each control line. The touch sensor 600 differs from the touch sensor 600 of the first and second configuration examples in that it has a control unit that can Here, the configurations different from configuration example 1 and configuration example 2 will be described in detail.

[0261] The output unit 103D is electrically connected to the signal line ML(j) and receives the signal A first detection signal based on the first control signal and a second detection signal based on the second control signal are generated from the detection signals. It has the function of separating the detection signal from 2.

This allows control signals to be provided to the first control line and the second control line at approximately the same time. and from the detection signal supplied to the signal line, a portion where the first control line intersects with the signal line and a portion where the second control line intersects with the signal line are detected. The detection signal detected at the intersection of the two control lines and the signal line can be separated. As a result, a novel touch sensor that is highly convenient and reliable can be provided.

[0263] For example, if a control signal that can be separated from the first control signal is used as the second control signal, Specifically, a signal having a first frequency is used as the first control signal, and A signal having a different second frequency may be used for the second control signal.

[0264] In this configuration example, the above configuration is combined with the configuration described in configuration example 1 or configuration example 2. For example, based on the state of the touch panel 500TP, Specifically, the winding part of the touch panel 500TP can drive the winding part. The touch sensor 600 provided in the non-contact area of ​​the touch panel 500TP is driven. The touch sensor 600 provided in the area wound on the winding section is not driven. For example, When combining this configuration example with the touch sensor configuration example 1, p and q are k1+1 or more and m or less. It becomes a natural number below.

A point having a control unit capable of supplying a difference between the detection signals supplied by the adjacent signal lines The point that the output unit 103D supplies the detection information using the touch sensor in the configuration examples 1 to 3 is the same as that in the configuration examples 1 to 3. This section describes the different configuration in detail and explains whether a similar configuration can be used. The above description is incorporated herein by reference where applicable.

[0267] The control lines include a first control line CL(p) and a second control line CL(q).

[0268] The signal line is a signal line ML that intersects with the first control line CL(p) and the second control line CL(q). Includes (j).

[0269] The signal line is a signal line ML that intersects with the first control line CL(p) and the second control line CL(q). Includes (j+1).

[0270] The control unit 103C outputs the first control signal modulated by the first method to the first control line CL(p). and providing a second control signal modulated in a second manner different from the first manner. and a function of supplying the control signal to the control line CL(q).

[0271] The output unit 103D is electrically connected to the signal lines ML(j) and ML(j+1).

[0272] The output unit 103D outputs a first control signal based on the detection signal supplied to the signal line ML(j). The first detection signal is separated from the second detection signal based on the second control signal. do.

[0273] Also, the output unit 103D derives a first control a third detection signal based on the signal and a fourth detection signal based on the second control signal. It has functions.

[0274] The output unit 103D compares the first detection signal with the third detection signal and outputs a signal based on the difference between the first detection signal and the third detection signal. The first detection information is compared with the second detection signal and the fourth detection signal, and a third detection signal is calculated based on the difference between the first detection information and the second detection signal. It has the function of supplying detection information of 2.

A control unit 103C capable of supplying a control signal modulated by the method, and a signal line ML(j ) which can separate the differently modulated detection signal from the detection signal fed to The signal line ML(j) detects a detection signal, and The detection signal detected by the signal line ML(j+1) adjacent to the signal line ML(j) is compared. It includes an output section 103D capable of supplying information.

[0276] This allows the control signals to be supplied to the first control line and the second control line at approximately the same time, From the detection signal supplied to the line, a portion where the first control line crosses the signal line and a portion where the second control line crosses the signal line are The detection signal detected at the intersection of the signal line and the adjacent It is possible to provide detection information in which noise components have been cancelled out based on adjacent detection information. As a result, a novel touch sensor that is highly convenient and reliable can be provided.

[0277] In this configuration example, the above configuration can be combined with the configuration described in configuration example 1 or configuration example 2. For example, a part of the touch sensor 600 can be controlled based on the state of the touch panel 500TP. Specifically, the touch panel 500TP is wound up on the winding part. The touch sensor 600 provided in the unwrapped area of ​​the touch panel 500TP is driven. The touch sensor 600 provided in the area wound up on the take-up portion is not driven. When combining the configuration example 1 of the touch sensor with the configuration example 2 of the touch sensor, p and q are k1+1 or more and m or less. becomes a natural number.

Alternatively, the liquid may be ejected from the nozzle 99 and sprayed. The liquid to be applied or sprayed may be water, a polar solvent, or the like.

[0292] By penetrating the liquid, the effects of static electricity that occurs during peeling can be suppressed. The release layer may be peeled off while being soaked in a liquid that dissolves the release layer.

[0293] In particular, when a film containing tungsten oxide is used for the peeling layer F2, liquids containing water must not penetrate the film. When the first peeled layer F3 is peeled off while being blown or sprayed, This is preferable because it can reduce the stress associated with peeling.

A laminate 81 having the above components is obtained (see FIG. 18(E-1) and FIG. 18(E-2)).

[0296] Various methods can be used to form the bonding layer 30. For example, The bonding layer 30 is formed by using a pen or a screen printing method. The material is cured by a method appropriate for the material used. For example, a photocurable adhesive is used for the bonding layer 30. In this case, light containing light of a predetermined wavelength is irradiated.

A cross-sectional view illustrating the configuration of the workpiece and the laminate is shown on the left side of FIG. 0, and a corresponding top view is shown. Shown on the right side except for Figures 19(C), 20(B) and 20(C).

[0301] The processed member 90 has the other surface of the bonding layer 30 formed on one side of the second peeled layer S3 instead of the base material S5. The point where the processed member 80 comes into contact with the surface of the processed member 80 is different from that of the processed member 80.

[0302] Specifically, instead of the base material S5, a second substrate S1 and a second release layer S2 on the second substrate S1 are , the second peeled layer S3 is in contact with the second peeling layer S2 on the other side thereof, and the second peeled layer S3 The difference is that one surface of the bonding layer 30 contacts the other surface of the bonding layer 30.

[0304] The details of the structure of the processed member 90 will be described in the sixth embodiment.

[0305] First Step A processed member 90 in which a peeling starting point F3s is formed near the end of the bonding layer 30 is prepared (FIG. 19). (B-1) and Figure 19 (B-2)).

[0306] The peeling starting point F3s is a structure in which a part of the first peeled layer F3 is separated from the first substrate F1. Yes.

[0307] For example, a method of piercing the first peeled layer F3 with a sharp tip from the first substrate F1 side or The first peeled layer F3 is peeled off by a method using a laser or the like (for example, a laser ablation method). A part of the peeling layer F2 can be partially peeled off. can be formed.

[0308] The second step One surface layer 90b of the processed member 90 is peeled off. As a result, a first remaining portion is left from the processed member 90. Get 90a.

[0309] Specifically, the peeling starting point F3s formed near the end of the bonding layer 30 is peeled off from the first substrate F1. The first peelable layer F2 is then separated from the first peeled layer F3 (see FIG. 19(C)). As a result, the first peeled layer F3, the bonding layer 30 having one surface in contact with the first peeled layer F3, A second layer S3 to be peeled, one surface of which is in contact with the other surface of the bonding layer 30, A second release layer S2 having one surface in contact with the other surface, and a second substrate S1 are arranged in this order.

[0310] In addition, ions are irradiated to the vicinity of the interface between the peeling layer S2 and the peeled layer S3 to remove static electricity. Specifically, the film may be irradiated with ions generated by an ionizer. stomach.

[0311] In addition, when the layer to be peeled off is peeled off from the peeling layer S2, liquid is applied to the interface between the peeling layer S2 and the layer to be peeled off S3. Alternatively, the liquid may be ejected from the nozzle 99 and sprayed. The liquid to be applied or sprayed may be water, a polar solvent, or the like.

[0312] By penetrating the liquid, the effects of static electricity that occurs during peeling can be suppressed. The release layer may be peeled off while being soaked in a liquid that dissolves the release layer.

[0313] In particular, when a film containing tungsten oxide is used for the peeling layer S2, liquids containing water must not penetrate the film. When the first layer S3 is peeled off while being blown or sprayed, This is preferable because it can reduce the stress associated with peeling.

[0314] The third step A first adhesive layer 31 is formed on the first remaining portion 90a (FIG. 19(D-1) and FIG. 19(D-2) )), and the first remaining portion 90a and the first support 41 are bonded together using the first adhesive layer 31. In this way, a laminate 91 is obtained from the first remaining portion 90a.

A laminate 91 is obtained in which the layer S2 and the second substrate S1 are arranged in this order (FIG. 19(E-1) ) and Figure 19(E-2)).

[0316] The Sixth Step A part of the second peeled layer S3 in the vicinity of the end of the first adhesive layer 31 of the laminate 91 is peeled off by the second substrate. It separates from the plate S1 to form a second peeling initiation point 91s.

[0317] For example, the first support 41 and the first adhesive layer 31 are cut from the first support 41 side, Also, a part of the second peeled layer S3 is peeled off along the edge of the newly formed first adhesive layer 31. The semiconductor device is separated from the substrate S1.

[0318] Specifically, the first adhesive layer S2 in the region where the second peeled layer S3 is provided on the peeling layer S2 31 and the first support 41 are cut using a blade having a sharp tip, and Along the edge of the formed first adhesive layer 31, a part of the second peeled layer S3 is attached to the second substrate S 1 (see FIG. 20(A-1) and FIG. 20(A-2)).

[0319] This step removes the edge of the newly formed first support 41b and the first adhesive layer 31. A peeling starting point 91s is formed near the portion.

[0320] The Seventh Step The second remainder 91a is separated from the laminate 91. 1a is obtained (see Figure 20(C)).

[0321] Specifically, the peeling starting point 91s formed near the end of the first adhesive layer 31 is peeled off from the second substrate 32.

[0323] In addition, when the layer to be peeled off is peeled off from the peeling layer S2, liquid is applied to the interface between the peeling layer S2 and the layer to be peeled off S3. Alternatively, the liquid may be ejected from the nozzle 99 and sprayed. The liquid to be applied or sprayed may be water, a polar solvent, or the like.

[0324] By penetrating the liquid, the effects of static electricity that occurs during peeling can be suppressed. The release layer may be peeled off while being soaked in a liquid that dissolves the release layer.

[0325] In particular, when a film containing tungsten oxide is used for the peeling layer S2, liquids containing water must not penetrate the film. When the first layer S3 is peeled off while being blown or sprayed, This is preferable because it can reduce the stress associated with peeling.

[0326] The 9th Step A second adhesive layer 32 is formed on the second remaining portion 91a (FIG. 20(D-1) and FIG. 20(D- See 2).

[0333] Example 1 of a method for producing a laminate having an opening in a support In the ninth step, the second support 42 is replaced with a support smaller than the first support 41b. The method for producing a laminate has the same steps as above, except that a second support 42b is used. This method produces a laminate in which a part of the second peeled layer S3 is exposed. (See FIG. 21(A-1) and FIG. 21(A-2)).

[0334] A liquid adhesive can be used for the second adhesive layer 32. Alternatively, the adhesive can be a liquid adhesive having reduced flowability and It is possible to use adhesive that has already been molded into individual pieces (also called sheet adhesive). When a sheet-like adhesive is used, the adhesive layer 32 protruding outside the second support 42b is In addition, the thickness of the adhesive layer 32 can be easily made uniform. .

[0408] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification. . EXAMPLES

[0409] In this example, a foldable touch panel according to one embodiment of the present invention was manufactured. Now, let us explain the results of the sensing test conducted on the touch panel in a bent state. Reveal.

[0410] [Touch panel production] In this embodiment, a touch sensor is provided on the opposing substrate (substrate on the display surface side) of a flexible display panel. In addition, the electrodes of the touch sensor are arranged in a mesh pattern. By making the shape of the metal mesh, the load capacity between the touch sensor and the display panel is improved. This structure allows the user to fold it freely. The thickness of the entire touch panel can be made thin enough to be practical. This suppresses the effect of noise from the display panel on the touch sensor, eliminating false detection and detection failure. This can prevent such problems from occurring.

[0411] The in-cell touch panel produced in this embodiment is driven by a projected capacitive touch panel. We adopted the mutual capacitance method, which is one of the methods.

[0412] FIG. 23(A) shows the structure of the touch panel produced in this example. The left side shows a schematic diagram of the touch panel, the right side shows the cross-sectional structure of the touch panel, and the The touch panel is a flexible display device. The touch panel has two flex boards. The flexible substrates are bonded to each other by an adhesive layer. A passivation layer is provided on the surface of the flexible substrate. An FET layer and an organic light-emitting diode (OLED) are formed on the insulation layer. On one flexible substrate, a touch sensor and a color filter are formed on a passivation layer. As shown in FIG. 23(A), the touch panel produced in this embodiment has a convex display surface. It is possible to bend it in a concave or concave manner.

[0413] FIG. 23B shows a more specific cross-sectional structure. On one flexible substrate side, There are partitions on both ends of the organic EL element, and spacers are placed on the partitions. The other flexible substrate has a passivation layer on the surface of the organic EL element side. The black matrix and the sensor metal electrodes that make up the touch sensor ), bridge metal, and color filters are formed in that order. The color filters are arranged over the organic EL elements. Between the sensor, the sensor electrode, the bridge electrode, and the color filter, an insulating layer (Inte The sensor electrode and the bridge electrode are The sensor electrodes and bridge electrodes are arranged on the display surface side. By arranging a black matrix, it is possible to suppress the reflection of external light caused by these. Furthermore, the sensor electrodes and bridge electrodes are arranged inside the width of the black matrix. This allows the effect on the aperture ratio (light extraction efficiency) to be minimized.

[0414] The touch panel is first fabricated by depositing a release layer, a passivation layer, a FET layer, and a glass substrate. An organic EL element was formed.

[0415] The transistor included in the FET layer (corresponding to transistor 502t) has a channel A transistor using an oxide semiconductor was used as the semiconductor to be formed. The oxide semiconductor has a c-axis oriented in a direction approximately perpendicular to the film surface, and the crystal grain boundaries in the film surface direction are Crystalline oxide semiconductors not identified (CAAC-OS: C-Axis Aligned Crystalline-Oxide Semiconductor was used.

[0416] CAAC-OS is a crystalline oxide semiconductor whose c-axis is aligned approximately perpendicular to the film surface. CAAC-OS has the characteristic that no grain boundaries are observed, so it is possible to It is possible to form a stable and uniform film on the substrate. Therefore, the CAAC-OS film is less likely to crack due to the stress generated by the application of heat.

[0417] In this example, an In--Ga--Zn-based oxide was used as the oxide semiconductor material.

[0418] The pixel electrode (lower electrode) is made of an alloy containing silver, which has a very high reflectance. Depending on the configuration of the device, a transparent electrode layer (optical layer) with an appropriate thickness is selected to obtain the microcavity effect. An optical adjustment layer (also called an optical adjustment layer) was formed on the pixel electrode.

[0419] The organic EL element used was a top-emission type white EL element. A tandem structure was formed in which a blue light-emitting unit and a yellow light-emitting unit were stacked.

[0420] In addition, a release layer, a passivation layer, a black matrix, etc. are formed on a glass substrate different from the above. A substrate, a sensor electrode, a bridge electrode, a color filter, and an insulating layer between them were formed.

[0421] Next, the two substrates were bonded together with an adhesive layer. The distance between the substrates (cell gap) was The thickness was adjusted to about 5 μm. After that, each substrate was The flexible substrate was attached to the film. A plastic substrate of this type was used.

[0422] In this manner, the touch panel was fabricated. The specifications of the touch panel are as follows: Diagonal 8.67 inches, pixel count 1080 x RGBY x 1920, resolution 254 ppi The aperture ratio is about 46%. The touch sensor uses a mesh-shaped sensor electrode, In the long side direction of the part, 48 transmitting electrodes are formed, and in the short side direction, 27 receiving electrodes are formed. The distance between the touch sensors was set to 4 mm. The touch sensor was placed over the 40 x 40 pixel area of ​​the display. Each area corresponds to one unit of the touch sensor.

[0423] The touch panel produced had a display surface that was flat when bent into a convex shape and a concave shape when bent into a concave shape. We confirmed that the display was normal both when the screen was bent. The surface can be detected correctly in each of the flat, convex, and concave parts. We confirmed that this is possible.

[0424] [Evaluation of parasitic resistance and capacitance at bends] The operation of bending the fabricated touch panel reduces the parasitic capacitance and parasitic capacitance between the receiving electrodes and the display panel. The effect on resistance was evaluated.

[0425] Measurements were taken with the touch panel display surface flat, bent convexly, and bent concavely. The test was carried out for three cases: when the radius of curvature R was 10 mm and when it was 5 mm. I researched the following.

[0426] The measurements were performed using an LCR meter (Agilent Technologies, 4275A). Ta.

[0427] Figure 24 shows the parasitic resistance and The number of measurements was six. bend in a concave shape (indicated as "inside bend"); Even in either state (denoted as bend) or with a curvature radius of 5 mm, It was confirmed that the variation rate of the parasitic resistance and the parasitic capacitance was extremely small, less than 0.1%. The results confirmed that bending the touch panel had very little effect on detection sensitivity. Done. EXAMPLES

[0428] Below, we will explain the effect of providing a touch sensor electrode on the light extraction efficiency. The results will be explained.

[0429] The touch panel produced in Example 1 used a top-emission type light-emitting element. The light from the element is extracted through the opposing substrate. Both flexible substrates with and without the optical transparency were fabricated. The pass rate was measured.

[0430] Figures 25(A), (B), and (C) show the measurement method and schematic cross-sectional views of the prepared samples.

[0431] FIG. 25(A) corresponds to a measurement system that directly measures the luminance of light from a reference light source. (B) is a sample with a mesh-shaped sensor electrode (denoted as w / metal mesh). ) corresponds to a measurement system for measuring the surface area of ​​a mesh-shaped sensor electrode. This corresponds to a measurement system for measuring samples that do not form metal meshes (referred to as w / o metal mesh). do.

[0432] The sample shown in FIG. 25(B) has a structure shown in FIG. 23(B) in which the The stacked structure of the upper layer and the position of the flexible substrate are different, but the two are the same. In FIG. 25(B), the flexible substrate is attached to the color filter side via an adhesive layer. It is being done.

[0433] The sample shown in Figure 25(C) has a black matrix and a color filter on the passivation layer. The flexible substrate is attached to the capacitor via an adhesive layer.

[0434] The measurement is performed by placing a sample on a surface light source and measuring the brightness of the light that passes through the sample upwards with a measuring instrument. The measurements were made in 12 places. The surface light source was an edge-type backlight (Schott Moritec The measurement equipment used was a color luminance meter (TOSHIBA Corporation, MEBL-CW145). The BM-5AS manufactured by Pukone Technohouse was used.

[0435] When the samples were placed on a surface light source and compared, no difference was visible to the naked eye. The measurement results are shown in Fig. 6. Fig. 26 shows the results when no sample is placed (Fig. 25(A)) at 100 %, and the measured brightness of each sample is shown as the transmittance. The transmittance of the sample with the sensor electrode formed was about 16.0%, and the transmittance of the sample without the sensor electrode formed was about 16.0%. The transmittance of the material was about 16.3%, and it was confirmed that there was almost no difference. The slightly lower transmittance of the sample with the sensor electrode is thought to be due to the difference in the laminate structure. do.

[0436] From the above, it has been found that the touch sensor of one embodiment of the present invention has almost no effect on the light extraction efficiency. It was confirmed that: [Explanation of symbols]
