[0033] The embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention This is not limited to the description below, and its form and details can be changed in various ways, as is the case for those skilled in the art. This will be easily understood. Furthermore, the present invention is not necessarily limited to the contents of the embodiments described below. It should not be interpreted in that way.
[0034] (Embodiment 1) Figure 1 illustrates a display device, a method for driving the display device, and one aspect of the program. Display devices described in terms of their form of application include, for example, light-emitting devices and liquid crystal display devices. Light-emitting devices are, For example, this includes an organic electroluminescent device.
[0035] As shown in Figure 1(C), the display device 100 includes a display unit 120 and a detection means 140. The display unit 120 includes, for example, the display surface 120a shown in Figure 1(A). The display surface 120a has an image It can display 110a.
[0036] The shape of the display device 100 is, for example, a ring formed by curving a strip-shaped structure. The component 100, for example, is flexible in at least part and has a gap 105. Therefore, it can be attached to the wrist by moving it to widen the gap 105. The device 100 can be worn not only on the wrist, but also on the neck, ankle, etc. Furthermore, a display device... The 100 can be attached not only to the wrist, neck, and foot, but also to columnar objects such as pipes and poles. The cross-section of the columnar object may be, for example, a circle or a polygon, but is not necessarily limited to these. The device 100 can be attached to objects other than columnar structures.
[0037] The display device 100 shown in Figure 1 has a gap 105, but the display device 100 has a gap 10 It is not necessary to have 5. In other words, the display device 100 is a curved, strip-shaped structure It can have a structure in which they are connected without breaks. Also, the shape of the display device 100 is It can have a structure similar to that used in typical wristwatches.
[0038] The display device 100 is, for example, an annular display device. An annular display device is, for example, a medium It is an empty, columnar display device. The cross-section of the display device 100 is, for example, shaped as shown in Figure 2. Yes, there is. The annular display device can be made into a shape that is connected without any breaks, as shown in Figure 1. As shown in A), it can also be made into a shape with a cut.
[0039] The display surface 120a is not only the front as shown in Figure 1(A), but also as shown in Figure 1(D). It can be extended to the outer peripheral surface on the opposite side. The display surface 120a is, for example, a display device 1 It can exist in a range greater than 180° and less than 360° along the circumferential direction of 00. The display surface 120a is, for example, along the circumferential direction of the display device 100, within a 360° range. It can exist. The display surface 120a is, for example, along the circumferential direction of the display device 100. , can be present across the entire surface. The display surface 120a is, for example, in the circumferential direction of the display device 100. Accordingly, it can exist in an angular range larger than the viewing angle of the display device 100.
[0040] An image 110a can be displayed on the display surface 120a. For example, an image 110a can be... For example, it can be an object that displays things like the time, weather, temperature, humidity, stock prices, and exchange rates. The object may be an icon or a widget. In addition to the object, wallpaper can be displayed on the display surface 120a. Display surface 1 In addition to the object, operation buttons can be displayed in 20a. Buttons include, for example, a button that returns to the previous screen, and a button that displays the home screen. These are buttons and keyboards. Also, instead of the aforementioned objects, the wallpaper and the controls are used. The "Create" button can be displayed.
[0041] Image 110a can be a still image or a moving image.
[0042] The detection means 140 is a detection means for detecting the position information of the display device 100. The position information of 00 may include the rotational position information of the display device 100. Display device 100 The rotational position information includes, for example, the direction of rotation and the angle of rotation of the display device 100. The rotation angle of the display device 100 is the tilt of the display device 100 before rotation (for example, The tilt of the display device 100 in the state shown in Figure 1(A), and the tilt of the display device 100 after rotation. This can be the difference from (for example, the tilt in the state shown in Figure 1(B)). Display device 1 The reference point for the tilt of 00 (i.e., the position where the tilt of the display device is set to 0°) shall be determined as appropriate. This is possible. The tilt of the display device 100 will be described later using Figure 8 and other references.
[0043] The direction of rotation of the display device 100 is, for example, arrows 115a and 115 in Figure 1(B). This includes the circumferential direction as shown in b. The direction of arrow 115a is the opposite direction to that of arrow 115b. The direction of rotation of the display device 100 is, for example, arrows 115a and 115 in Figure 1(B). This may include circumferential and perpendicular directions, as in b. The rotational position information of the display device 100 is displayed The rotational speed (i.e., angular velocity) of the device 100 may be included.
[0044] The detection means 140 is, for example, a detection means for detecting the tilt of the display device.
[0045] Using the detection means 140, position information based on the tilt of the display device 100 with respect to the vertical direction is obtained. It can be detected. The aforementioned vertical direction is the direction of gravity. The aforementioned vertical direction is the direction of the weight It can also be expressed as the direction indicated by the thread when the object is suspended by a thread. A certain point on the display device 100 A line segment connecting the center point of rotation of the display device 100 and a vertical line passing through the center point are displayed. The angle between the line segment connecting one of the points where the device 100 intersects and the center point is defined as the angle in the vertical direction. This can be defined as the tilt of the display device 100.
[0046] The detection means 140 is, for example, an acceleration sensor or a gyroscope.
[0047] The acceleration sensor is, for example, a two-axis acceleration sensor or a three-axis acceleration sensor.
[0048] A single-axis acceleration sensor can also be used as the aforementioned acceleration sensor.
[0049] By providing multiple acceleration sensors, a configuration can be adopted to detect positional information. Cut.
[0050] The detection means 140 is a sensor that detects tilt other than the acceleration sensor and gyro sensor. It is possible.
[0051] If, for example, an acceleration sensor is used as the detection means 140, the detection means 140 is provided. The tilt of the device can be detected. The accelerometer detects the acceleration due to gravity. The tilt of the device can be detected.
[0052] For example, when an acceleration sensor is mounted on a substrate and the substrate is kept horizontal, The velocity sensor has a downward (direction of gravitational acceleration) corresponding to +1g (where g is the acceleration due to gravity) A force is applied. Here, the downward direction when the accelerometer is held horizontal is the Z-axis direction, and the Z-axis The directions perpendicular to the direction and the directions that are perpendicular to each other are defined as the X-axis direction and the Y-axis direction. The direction, Y-axis direction, and Z-axis direction change in response to changes in the tilt of the accelerometer.
[0053] When an acceleration sensor is mounted on a substrate and the substrate is kept horizontal, the acceleration sensor It detects an acceleration of +1g (where g is the acceleration due to gravity) in the Z-axis direction. The substrate is moved in the X-axis direction. If tilted 90° in the Y-axis direction, the accelerometer will show 0g in the Z-axis direction (where g is the acceleration due to gravity). The acceleration (in degrees) is detected. When the circuit board is turned upside down (i.e., the circuit board is kept horizontal and the acceleration is detected), the acceleration is detected. (If the sensor is positioned below the substrate), the accelerometer will have a response of -1g in the Z-axis direction. Detect the acceleration (where g is the acceleration due to gravity).
[0054] Similarly, the accelerometer can also detect acceleration in the X-axis direction. Example For example, when the substrate is kept horizontal, the acceleration sensor is 0g in the X-axis direction. The acceleration (where g is the acceleration due to gravity) is detected. The circuit board is rotated 90° with the Y-axis of the acceleration sensor as the axis of rotation. When tilted (that is, when the accelerometer detects an acceleration of 0g (where g is the acceleration due to gravity) in the Y-axis direction) (When the circuit board is tilted 90° while maintaining the detection state), the accelerometer moves in the X-axis direction. Detects acceleration of +1g (where g is the acceleration due to gravity) or -1g (where g is the acceleration due to gravity). For example. When the acceleration sensor detects a positive acceleration in the X-axis direction, the display device 100 displays a positive value. When it rotates in that direction and the accelerometer detects negative acceleration in the X-axis direction, it displays It can be defined that the device 100 rotated in the negative direction.
[0055] Figure 8 shows a cross-sectional view of the display device 100 equipped with the detection means 140. For example, Figure 8 The direction to the right of the detection means 140 (in this case, the acceleration sensor) in (B) is the X-axis of the acceleration sensor. The positive direction in this figure, and the left direction, are considered the negative direction on the X-axis of the accelerometer. Figure 8(B) If it is rotated from the state in Figure 8(A), then, using the state in Figure 8(B) as a reference, it will return to the state in Figure 8(A). The tilt of the display device 100 is an angle θ (θ is between -90° and less than 0°). The accelerometer detects a negative acceleration g·sinθ (arrow 145a) in the X-axis direction. In this case, it can be defined that the display device 100 rotated in the negative direction.
[0056] When the rotation is performed from the state shown in Figure 8(B) to the state shown in Figure 8(C), using the state shown in Figure 8(B) as the reference point, The tilt of the display device 100 in Figure 8(C) is an angle θ (where θ is greater than 0° and less than or equal to 90°). Therefore, at this time, the acceleration sensor detects a positive acceleration g·sinθ (arrow 14) in the X-axis direction. 5b) is detected, and in this case, it can be defined that the display device 100 has rotated in the positive direction. ru.
[0057] Similarly, the accelerometer can also detect acceleration in the Y-axis direction.
[0058] The display device 100 is in the state shown in Figure 8(D) (for example, θ is greater than 90° and less than 180°) In the state shown below, the acceleration sensor detects a positive acceleration g·sinθ in the X-axis direction. The system detects angles where θ is greater than 90° and less than or equal to 180°. Then, the conditions shown in Figures 8(C) and 8(D) are obtained. It can become difficult to distinguish between states. However, in this case, the Z-axis direction of the acceleration sensor When considered together with the detection results, it is possible to distinguish between the states in Figure 8(C) and Figure 8(D). For example, in the state shown in Figure 8(C), the acceleration sensor detects positive acceleration in the Z-axis direction. This is because, in the state shown in Figure 8(D), negative acceleration is detected in the Z-axis direction.
[0059] Therefore, by providing an acceleration sensor on the display device 100, the tilt of the display device 100 can be detected. This can be detected. As a reference for the tilt of the display device 100, for example, the state shown in Figure 8(B) The state can be defined as the tilt of the display device 100 being 0°.
[0060] The tilt of the display device 100, which is equipped with an acceleration sensor, is detected by the acceleration sensor. It can be determined from acceleration using trigonometric functions. The tilt of the display device 100 is 90° or When the change occurs near -90°, the change in acceleration detected by the acceleration sensor is It becomes smaller. As a result, the sensitivity of the display device 100 to the tilt of the display device 100 is It will decrease. Therefore, multiple acceleration sensors are placed at different positions on the display device 100 (for example) If multiple acceleration sensors detect different accelerations, the display device 100 will be positioned at different locations. (Placed in this position) and when all accelerometers are tilted at approximately 90° or -90° simultaneously Since the acceleration of the tilt in the foyer is no longer detected, the tilt of the display device 100 can be detected with high accuracy. It can be released.
[0061] The aforementioned location information may include geographical location information. Geographical location information includes, for example, This is location information expressed in latitude and longitude coordinates. The aforementioned geographical location information also includes height. It may also include directional coordinates. In this case, the detection means 140 detects geographical location information. What is possible is necessary. For example, a satellite positioning system to detect geographical location information. Specifically, the Global Positioning System (GPS) You can use em).
[0062] Figure 1(A) shows the display device 100 before it rotates in the circumferential direction. Figure 1(B) shows the circumferential direction The display device 100 is shown after being rotated in the direction of arrow 115b. Display position of image 110a If the device is fixed to the display device 100, the display device 100 will move in the circumferential direction (arrow). When it rotates in the direction of 115b (for example, when a wristwatch is used as the display device 100) (When the wristwatch rotates around the arm as an axis in the direction of arrow 115b), as shown by the dotted line in Figure 1(B) In addition, the display position of image 110a moves relative to the line of sight in the direction of arrow 115b. For example, in Figure 1(B), image 110a moves from the front to the top of the display surface 120a. Therefore, it may become difficult to see. Also, the display device 100 is more than in the state shown in Figure 1(B). Furthermore, when rotated in the direction of arrow 115b, image 110a is the outer surface opposite to the display surface 120a. It is difficult to move to and even to see.
[0063] The annular display device 100 includes a detection means 140 for detecting the position information of the display device, and It has a display unit 120 that displays an image at a display position determined based on location information. This allows the image to be moved to a more visible position even when the display device 100 moves. Preferably, the display device 100 can display the image in the same position as it was before it moved. It is possible.
[0064] The position information of the display device 100 is rotational position information based on the circumferential rotation of the display device 100. This may include the following: In this case, the display position of the image is determined by the rotation of the display device 100 in the circumferential direction. The direction can be set to move in the opposite direction. For example, the display device 100 is an arrow When rotated in the direction of 115b, the display position of the image on the display surface 120a is indicated by the arrow. It can move in the direction of 115a. Therefore, when the display device 100 rotates, However, the image can be moved to a more visible position, preferably as shown in Figure 1(B). As shown, image 110a moves to become image 110b, and the display device 100 rotates in the circumferential direction. The image can be displayed in the same visible position both before and after rotation. .
[0065] In addition, as the display position of the image moves on the display surface 120a, the liquid crystal elements and EL elements Burn-in of the display unit 120, which has display elements such as sub-display elements, can be suppressed. The lifespan of the display device 100 can be extended.
[0066] Furthermore, the display device 100 does not need to be equipped with a mechanism to suppress burn-in, such as a screen saver. Also, burn-in of the display unit 120 can be suppressed, so the display device 100 can be made simpler It can be configured as follows.
[0067] The detection means 140 can be a means for detecting the displacement of the display device 100. In addition, the method for driving the display device includes the steps of detecting the displacement of an annular display device and based on the displacement The process includes the steps of determining the display position and displaying the image at the said display position. This is possible. Furthermore, the driving method can be controlled by a program.
[0068] Figure 2 shows a more detailed example of how to determine the display position of an image.
[0069] Figure 2(A) shows the case where the cross-section of the display device 100 is considered to be a circle.
[0070] Figure 2(A) assumes that the cross-section of the display device 100 is a circle with radius r (r>0), and the table This shows the case where the display device 100 is rotated by an angle θ radians (θ > 0) in the direction of arrow 115b. At this time, the display position of the image is in the opposite direction to the rotation direction of the display device 100, that is, the arrow. It can be determined that the movement in the direction of mark 115a is a length rθ, which is the product of the angle and the radius. In Figure 2(A), image 110a moves in the direction of arrow 115a and image 110b It is displayed as follows.
[0071] Figure 2(A) shows the case where the cross-section of the display device 100 is considered to be a perfect circle. The cross-section of the display device 100 itself does not necessarily have to be a perfect circle. However, if the shape is close to a perfect circle, the actions described in Figure 2(A) can be performed. Furthermore, even if the cross-section of the display device 100 is not close to a perfect circle, as shown in Figure 2(A) By implementing the measures described, it is possible to use simple methods as shown in Figure 2(A) and to achieve a higher level of efficiency. The image can be moved to a more visible position.
[0072] Figure 2(B) shows the case where the cross-section of the display device 100 is considered to be elliptical. In B), the distance r (r>0) between the center of rotation and the display device 100 in the radial direction. Although it is not constant, if the major and minor axes of the ellipse are known, the shape of the ellipse can be determined. Therefore, the display The length of the elliptical arc corresponding to the rotation angle θ in radians (θ > 0) of device 100 is determined. Therefore, the length by which the display position is moved can be determined. Thus, the cross-section of the display device 100 is Even when considered as an ellipse, the image can be moved to a more visible position.
[0073] In Figure 2(C), the cross-section of the display device 100 is assumed to be an arbitrary curve containing a closed curve. Let's illustrate the case. In Figure 2(C), the center point of rotation and the display device 100 in the radial direction. The distance r (r>0) is not constant, but the distance r is a value determined by the angle θ (θ>0) f(θ ) can be measured in advance. In this case, before the display device 100 rotates The position where image 110a is displayed is at an angle θ0 radians (θ0>0), and the display device 100 If the rotation angle is Δθ radians (Δθ>0), then the length of movement of the display position (along the arc) The length from image 110a to image 110b is calculated using the integration interval [θ0, θ0+Δθ]. It can be expressed as a definite integral of f(θ) with respect to the variable θ.
[0074] Therefore, regardless of the cross-sectional shape of the display device, one aspect of the present invention can be implemented. can.
[0075] The shape of the display device 100 shown in Figure 1(A) is a strip-shaped structure. Image 110a moves to Image 110b along the longitudinal direction of the strip-shaped structure. Examples are shown, but are not limited to these. For example, the strip-shaped structure of the display device 100 In accordance with the rotation of the object in the shorter direction, relative to the display device 100, and the strip-shaped structure The display position of the image can be moved in the opposite direction to the rotation of the structure in the shorter dimension. In this case, the display surface 120a extends, for example, so as to curve in the shorter direction of the strip-shaped structure. It is preferable that it be present. The image you want to see is on the back surface of the display surface 120a and the display surface 120a Rather than a hard-to-see area such as the side in the aforementioned short direction, the front of the display surface 120a It can be displayed in an area that is easy to see.
[0076] In the above, an example is given in which the image is moved in the longitudinal direction of the strip-shaped structure, and the image is moved in the strip-shaped We have shown an example of moving a structure in the shorter direction, but these can be implemented in combination. It is possible to do either one or the other. Furthermore, it is possible to switch between them. It is also possible.
[0077] For example, if a wristwatch is used as the display device 100, you can watch the wristwatch display while lying down. There are cases where this is the case. For example, when standing, the display surface 120a that is visible when looking at the back of the hand There are cases where you view the display area (for example, as shown in Figure 1(A)), and when you are lying down... When viewing the display area of the display surface 120a that is visible when looking at the palm of the hand (for example, Figure 1( There are cases where it can be viewed as in D).
[0078] As shown in Figure 9, the camera unit 170 provided on the display device 100 is used to capture the user's face. The image is captured, and the display position of the image is determined based on the position of the face in the captured image 180. can.
[0079] Figure 9(A) shows the case where the display device 100 is located below the face. When wearing a wristwatch, if you are standing, the watch will be below your face. I often look at my watch while I'm in that state.
[0080] In the state shown in Figure 9(A), assume that the image you want to see is displayed in a clearly visible position. When the camera unit 170 is used to image a face, as shown in Figure 9(C), the face is captured in the image 18 It is located above the number 0.
[0081] Figure 9(B) shows the case where the display device 100 is located above the face. When wearing a wristwatch, if you are sleeping, the watch will be above your face. I often look at my watch while I'm sitting down.
[0082] When a face is imaged using the camera unit 170 in the state shown in Figure 9(B), the result will be as shown in Figure 9(D). The face is located at the bottom of image 180.
[0083] The position of the face in Figure 9(D) is lower than the position of the face in Figure 9(C). By moving the image on the display surface in the direction of arrow 115c, the state shown in Figure 9(B) can be reached. Even if there is a viewer, the image can be displayed in an easily visible position. The direction of arrow 115c is for the viewer The direction from which the object can be directly observed can be described as the direction from top to bottom.
[0084] Face in the captured image 180 when the display device 100 moves relative to the viewer. The relationship between the magnitude and direction of the positional displacement and the length and direction of the image movement on the display surface is It is preferable to prepare in advance.
[0085] Furthermore, when the display device 100 moves relative to the viewer, the captured image 180 The magnitude and direction of the displacement of the face position in the image 180, the area of the face in the captured image 180, and the display surface It is preferable to prepare in advance the relationship between the length and direction of the image movement described above. When the distance between the viewer and the display device 100 changes, the area of the face in the captured image 180 changes. Furthermore, when the display device 100 moves relative to the viewer, the captured image 180 The magnitude of the displacement of the face position changes. Therefore, the area of the face in the captured image 180 is different from the magnitude of the displacement of the face position. By using relationships, images can be moved more precisely on the display surface. ru.
[0086] However, a relationship with the area of the face in the captured image 180 is not necessarily required. For example, table When a wearable device such as a wristwatch is used as the display device 100, the viewer and the display The distance of the display device 100 can be considered to remain almost unchanged.
[0087] For example, in a display device including a camera unit, the display device and the object to be imaged are in a first phase When in a relative positional relationship, the first camera unit is used to image the object to be imaged. When the step, the display device, and the object to be imaged are in a second relative positional relationship, A second step of using the camera unit to image the object to be imaged, and the first step A portion of the object to be captured in the first image captured in the first step, and in the second step The magnitude of the positional displacement of the part of the object being imaged in the second image captured in the image. A third step of determining the display position of the image to be displayed on the display device based on its orientation and direction. A method for driving a display device, including, can be implemented. Furthermore, this driving method can be programmed It can be controlled.
[0088] As illustrated above, when the display device 100 moves relative to the viewer, Even if you want to display the image you want to see in the desired position on the display surface, for example, Display device 1 moved relative to the viewer with respect to the position of the face in the captured image 180 If the position of the face in the captured image 180 taken at 00 is located at the top, the image It can be moved on the display surface in the direction of arrow 115d.
[0089] The display device 100 moves relative to the viewer, and the display device also points to the arrow 115c. Even when rotated in directions such as arrow 115d, the image you want to see will be displayed in a position that is easy to view. This can be shown. In this case, the techniques described herein, such as those in Figure 2 and Figure 9, can be combined. Just let them do it.
[0090] It is preferable to provide multiple camera units 170. This allows for a wider imaging range of one camera unit. Even when the face is located outside of 75, the face can still be imaged by other camera units. Therefore, based on the position of the face in the captured image 180, the display position of the image on the display surface It is possible to determine this.
[0091] The display surface 120a preferably has a curved surface.
[0092] In the curved display surface 120a, the outer periphery and side surfaces opposite to the display surface 120a are not visible. This is a difficult area. Not just the outer periphery on the opposite side, but also off the front of the display surface 120a. As the degree increases, visibility decreases. Therefore, in areas where visibility decreases... By lowering the brightness, power consumption can be reduced.
[0093] For example, the tangent plane of the first display area on the display surface 120a and the tangent plane of the second display area When the angle with is greater than 0 and 180° or less, the brightness of the second display area is set to the first The brightness of the display area can be made smaller than that of the first display area. The tangent plane of the first display area and the The angle formed by the tangent plane of the second display area is such that the first display area and the second display area are separated. The angle that becomes larger with respect to this can be considered as the first display area and the second display area These are regions that do not overlap with each other.
[0094] Here, the first display area is, for example, the front of the display surface 120a, and the second is The display area is, for example, the side surface of the display surface 120a. The tangent plane of the first display area and the second The case where the angle between the display area and the tangent plane is 90° is, for example, when the first display area is This is the case where it is the front view and the second display area is the side view. Tangent plane of the first display area The case where the angle between the second display area and the tangent plane is 180° is, for example, the first display area. This is the case where the area is the front surface and the second display area is the outer surface on the opposite side.
[0095] The angle between the tangent plane of the first display area and the tangent plane of the second display area is 90° or more. When the first display area is visible, the second display area is visible. Even that is difficult.
[0096] Therefore, for example, the tangent plane of the first display area and the tangent plane of the second display area When the angle is greater than 0 and less than 90°, the brightness of the second display area is set to the first display area. It can be made smaller than the brightness of the display area. For example, the tangent plane of the first display area and If the angle between the second display area and the tangent plane is 90° or more and 180° or less, the second The brightness of the display area of the first display area is made less than the brightness of the second display area. The display area can be turned off.
[0097] For example, the angle between the tangent plane of the first display area and the tangent plane of the second display area is When the viewing angle of the display device 100 is greater than or equal to 180°, the brightness of the second display area is set to the front To make the brightness of the first display area less than the brightness of the second display area, or to turn off the display of the second display area. It is possible. When the first display area is the front, the first display area The angle between the tangent plane and the tangent plane of the second display area is 1 / 2 of the viewing angle of the display device 100. When the angle is greater than or equal to 180°, the brightness of the second display area is reduced to the brightness of the first display area. The value can be reduced to less than a degree, or the display of the second display area can be turned off.
[0098] By adjusting the current flowing to the display elements of the display unit 120 and the voltage applied to them, the display surface 12 The brightness of 0a can be adjusted.
[0099] Wearable devices (such as watches) are devices that are intended to be carried around. In this regard, it is important to suppress power consumption. As described above, one of the display surfaces 120a By reducing the brightness of the part or turning off the display, the power consumption of the display device 100 is reduced. The power can be reduced. In addition, the brightness of the display surface 120a can be reduced, or the display Turning it off has the synergistic effect of extending the lifespan of the display device.
[0100] The display device 100 can be equipped with a touch panel. This reduces the area for operation buttons on the display surface 120a, so the display The display surface 120a can be made larger, or the display device 100 can be made smaller. ru.
[0101] The touch panel can detect operation information on the display surface 120a, as shown in Image 1. The display position of 10a can be determined based on the operation information. For example, display surface 120 The operation information includes actions such as tracing a with a finger or pen, or tapping the display surface 120a. It is possible.
[0102] For example, if you move your finger along the circumferential direction of the display surface 120a, from top to bottom in Figure 1(B) By tracing with a pen or similar object, the image 110a is moved on the display surface 120a in the direction of the arrow 115a. It can be moved. In other words, by tracing the display surface 120a with your finger or a pen, you can move it to image 1. 10a can be scrolled. In the direction of arrow 115a in Figure 1(B), display surface 1 By tracing 20a with your finger or a pen, you can create the opposite side of the display surface 120a, as shown in Figure 1(D). The image displayed on the outer periphery of the side is shown on the front of the display surface 120a, as shown in Figure 1(B). It can be moved.
[0103] In the annular display device 100 shown in Figure 1(B), for example, in the direction of arrow 115a When you scroll the display surface 120a in that direction, image 110a is the same as the display surface 120a in Figure 1(B). Move to the bottom. Furthermore, if you scroll the display surface 120a in the direction of arrow 115a, the image Image 110a is viewed from the front as shown in Figure 1(B), and from the opposite outer surface, i.e., Figure 1(D). Move to the bottom of the display surface 120a. Furthermore, scroll the display surface 120a in the direction of arrow 115a. When rolled, image 110a moves to the top of display surface 120a in Figure 1(D), and further, When the display surface 120a is scrolled in the direction of arrow 115a, the display surface 120a in Figure 1(B) Image 110a appears from the top.
[0104] The scrolling operation described above occurs when the display surface 120a moves circumferentially, as shown in Figure 1(B). It can be performed even if there is a break in the direction, and the display surface 120a is seamless in the circumferential direction. It can be done even when connected.
[0105] Image 110a does not fit in front of the display surface 120a shown in Figure 1(A), and is shown in Figure 1(D). It may extend to the outer peripheral surface on the opposite side of the display surface 120a. In this case, for example, The action of double-tapping image 110a triggers the reduction of image 110a. It is possible.
[0106] When reducing the size of image 110a, reduce it without changing the aspect ratio of image 110a. This prevents image distortion.
[0107] As shown in Figure 3(A), the display device 100 may include a storage medium 130. The program for controlling the driving method of the display device 100 is stored in the storage medium 130. This is possible. The storage medium 130 is a storage medium that can be read by a computer. 30 can be electrically connected to the detection means 140 and the display unit 120. 40 and the display unit 120 can be electrically connected.
[0108] As shown in Figure 3(B), the storage medium 130 may be located outside the display device 100. In this case, the storage medium 130 is connected to the detection means 140 and via the terminals of the display device 100. The display unit 120 can be electrically connected. Alternatively, the storage medium 130 can be connected to the detection means 1 40 and the display unit 120 can be connected wirelessly. In addition, the detection means 140 and The display unit 120 can be connected wirelessly.
[0109] Components (e.g., display unit 120, storage medium 130, detection means 140) are wired together. By connecting with a short circuit, poor contact can be prevented. Furthermore, the display device 100 is small It can be typed.
[0110] If the detection means 140 detects a displacement of the display device 100, the image is rewritten. If the displacement of the display device 100 is not detected, the image will not be rewritten, or The program instructs the storage medium 130 to retain the displayed image. This allows for reduced power consumption required for image rewriting.
[0111] Wearable devices (such as watches) that can be carried around while disconnected from a power source. In devices where this is anticipated, reducing power consumption is important. In other words, The above configuration can suppress power consumption, and is suitable for wearable devices (for example, on the wrist). This applies to devices that are intended to be carried around while disconnected from a power source, such as (a total). It is more effective when applied to devices that are connected to a power source.
[0112] As shown in Figure 3(C), the display device 100 can include a battery 150. Battery 150 is, for example, a primary or secondary battery. Display device 100 is battery 1 If it includes a rechargeable battery as 50, then the battery 150 can be charged wirelessly. It can also be charged by cable connection. The display device 100 is a power generation mechanism It may include 160. The power generated by the power generation mechanism 160 is stored in the secondary battery. The power generation mechanism 160 can, for example, use a solar cell, a thermoelectric conversion element (for example, a Peltronic cell), etc. It is a (YE element). A wearable device such as a wristwatch is used as the display device 100. In such cases, it is preferable to use a thermoelectric conversion element as the power generation mechanism 160. This is because This is because it is possible to generate electricity constantly due to the temperature difference between body temperature and the outside temperature. However, The electrical mechanism 160 is not limited to this, and for example, it may convert the rotational energy of the display device 100 into power. It can be a mechanism that converts to electricity, or a mechanism that converts vibration energy into electricity. The mechanism that converts the rotational energy of the device 100 into electricity is performed in accordance with the rotation of the display device 100. It can generate electricity and transmit that generated electricity to a secondary battery. A gyro sensor may be used as the power generation mechanism 160.
[0113] The display device 100 moves the display position of the image when the display device moves, as described above. The system switches between a mode where the display moves and a mode where the image display position does not move even when the display device moves. It can be done.
[0114] Figure 4 shows an example of how to drive the display device 100. First, the display position of the image is specified. Step S110 is performed. If the display device 100 moves as a result of step S110, the image The system switches to a mode that moves the display position.
[0115] The image display position can be set in advance. Alternatively, the image display position can be set by default. It may be set to FORT. In these cases, step S110 can be omitted. The display device is already set to a mode that moves the image display position when the display device moves. This is preferable.
[0116] Next, the displacement of the display device 100 is detected (S120). If the displacement of the display device 100 is not detected, perform step S130. In this case, do not perform step S130.
[0117] The displacement of the display device 100 includes rotational displacement based on the circumferential rotation of the display device 100. This may be possible. The rotational displacement includes, for example, the direction of rotation and the angle of rotation.
[0118] Instead of step S120, as shown in Figure 5, the circumferential displacement of the display device 100 is The detection step (S220) can be performed.
[0119] The circumferential displacement of the display device 100 is detected by a detection sensor such as an acceleration sensor or a gyroscope. It can be detected by the stage.
[0120] The acceleration sensor is, for example, a two-axis acceleration sensor or a three-axis acceleration sensor.
[0121] A single-axis acceleration sensor can also be used as the aforementioned acceleration sensor.
[0122] Displacement can be detected using multiple acceleration sensors.
[0123] Displacement is detected by sensors that detect tilt other than acceleration sensors and gyroscopes. It is possible.
[0124] The aforementioned displacement may include geographical displacement. Geographical displacement refers to, for example, a difference in latitude and longitude. This is the displacement on the represented coordinate system. The geographical displacement further includes the coordinate system in the height direction. It is also possible to detect geographical displacement, for example, using satellite positioning systems, specifically all The Earth positioning network can be used.
[0125] Next, the display position of the image is moved based on the displacement of the display device 100 (S130). As shown in Figure 5, the display position of the image is adjusted according to the amount of displacement of the display device 100. A step (S230) can be performed to move in the reverse direction. Or, see Figure 2 and its explanation. The display position of the image can be moved by the method described in part.
[0126] Next, it is determined whether or not the display position of the image has been removed (S140). If it is determined that the position setting has been canceled, the display position of the image will be changed when the display device moves. Exit the moving mode and switch to a mode where the image display position does not move even if the display device moves. If it is not determined that the display position of the image has been removed, repeat step S1. Perform step 20.
[0127] As described above, there is a mode in which the display position of the image moves when the display device moves, and the display device By switching to a mode that does not move the image display position even when the system moves, consumption It can reduce power consumption.
[0128] Wearable devices (such as watches) that can be carried around while disconnected from a power source. In devices where this is anticipated, reducing power consumption is important. In other words, The above configuration can suppress power consumption, and is suitable for wearable devices (for example, on the wrist). This applies to devices that are intended to be carried around while disconnected from a power source, such as (a total). It is more effective when applied to devices that are connected to a power source.
[0129] When repeating steps S120, S130, and S140, the frequency of repetition can be adjusted as appropriate. It can be set. For example, step S120 can be set to be greater than 0 seconds and less than or equal to 1 / 60 of a second. This can be done once per step. Alternatively, in step S140, the display position of the image After it is determined that the designation has not been removed, the interval until step S120 is started is 0 It can be greater than a second and less than or equal to 1 / 60th of a second.
[0130] In step S110, for example, tap on the image 110a displayed on the display surface 120a. The trigger is either by clicking or by approaching the image 110a displayed on the display surface 120a. - This allows you to specify the display position of the image.
[0131] A button for specifying the display position of the image can be provided on the display device 100. If you touch or approach image 110a to specify the position, please be careful. This could potentially cause an error, moving the object. Specify the display position of the image. The presence of a button on the display device 100 reduces the possibility of malfunction. It is possible.
[0132] In step S110, for example, the display position of image 110a is changed using sound as a trigger. It can be specified. For example, by typing "Specify display position", image 110a You can specify the display position.
[0133] In step S110, for example, tap, double tap, hold, flick, ping Actions such as clicking can be used as triggers.
[0134] In step S110, for example, the action of tracing the display surface 120a with a finger or pen is performed. As a rigger, you can specify the display position of the image. For example, display surface 120a can be set downwards. After tracing in one direction, you can use tracing to the right as a trigger. In other words, L This is a motion that resembles drawing the character "no". Such a motion can be called a gesture. (Display surface) After tracing 120a downwards, continue tracing to the right, and then continue tracing downwards again. It can also be triggered by swiping downwards and then swiping to the left. It can also be called a rigger. One or more of the following directions can be combined: up, down, right, left. You can use gestures that are set to a specific direction. Furthermore, you can use gestures that combine diagonal directions. It can be used. It can also be triggered by actions that draw curves, such as circles. Display surface When tracing 120a, it is not necessary to make contact with the display surface.
[0135] Swiping upwards or downwards is sometimes used to scroll through images. Swiping to the right or left is used to move to an adjacent display area. This can happen. Therefore, two directions are selected from the following directions: up, down, right, left, etc. When triggered by a continuous tracing motion in one direction, distinguish it from a motion that traces in only one direction. This is preferable because it allows for this.
[0136] The gesture is triggered only while the button on the display device 100 is pressed. You can configure this setting once you switch to this mode.
[0137] The methods described herein can be controlled by a program.
[0138] This embodiment can be combined with other embodiments and other matters described herein. Cut.
[0139] (Embodiment 2) Figure 6 will be used to explain how images are displayed on the display surface 120a.
[0140] An object that displays images such as a clock, weather, temperature, humidity, stock prices, and exchange rates. It can be an icon or a widget. It may be present. In addition to the object, wallpaper may be displayed on the display surface 120a. Yes, it is possible. In addition to the object, operation buttons can be displayed on the display surface 120a. Yes, it is possible. The aforementioned operation buttons include, for example, a button that has the function of returning to the previous screen, and a button that returns to the home screen. These are buttons and keyboards that have the function of displaying information. Also, instead of the aforementioned object, The aforementioned wallpaper and operation buttons can be displayed.
[0141] In this embodiment, the image is described as an object. Therefore, the object It can also be implemented by replacing it with another image.
[0142] As shown in FIG. 6, a plurality of objects can be displayed on the display surface 120a. In particular, a plurality of objects can be displayed in a visible area of the display surface 120a (for example, the front of the display surface 120a). Of course, objects may also be displayed on the outer peripheral surface on the opposite side of the display surface 120a.
[0143] As shown in FIG. 6(A), objects can be displayed on the display surface 120a such that a plurality of objects are arranged along the circumferential direction of the display device 100. The number of objects displayed on the display surface 120a is not limited to three, and may be one, two, or four or more.
[0144]
[0145]
[0146]
[0147] Objects can be displayed in a matrix. Objects to be displayed on display surface 120a The number of units is not limited to six; it can be one, two, three, four, five, or even seven. That's fine too.
[0146] The display device 100 may be equipped with a telephone function. The telephone function is an object. A button to execute this action can be displayed on the display surface 120a.
[0147] Objects include, for example, clocks, weather, temperature, humidity, stock prices, exchange rates, maps, electronic money, These are blood pressure, body temperature, and pulse. This applies when the display device is a wearable device such as a wristwatch. It is preferable to display blood pressure, body temperature, pulse, etc. as objects. Pulse rate and other vital signs are measured by a person wearing a wearable device such as a wristwatch, or by the blood pressure and body of an animal. It is not necessarily limited to temperature and pulse. For example, blood pressure and body temperature of people or animals in remote locations. It can also display pulse rate.
[0148] When using weather as an object, you can display things like sunny, cloudy, rainy, etc. Yes, it's possible. For the weather, you can display the weather at the time you check the display, or you can display the weather forecast. It is permissible to display it. The weather displayed will change according to the region where the display device is located. It is preferable to do so. In this case, in order to detect the geographical location information of the display device, for example, a satellite It can utilize a star-based positioning system, specifically the Global Positioning Network.
[0149] This embodiment can be combined with other embodiments and other matters described herein. Cut.
[0150] (Embodiment 3) This embodiment shows an example of an arm-mounted display device. A perspective view of the display device is shown in Figure 7. vinegar.
[0151] As shown in Figure 7, the display device 200 is a flexible display on the curved surface of the support structure 210. It has a section 220.
[0152] The shape of the support structure 210 is a curved bracelet made from a strip-shaped structure. 210 is at least partially flexible, and moves in a direction that widens the gap 205. Therefore, it can be worn on the wrist. The support structure 210 shown in Figure 7 has a structure that allows its end to bend. The central part, which is far from the ends, hardly fluctuates. Therefore, the support structure In the central part of the body 210, the curvature remains the same as when it was attached and fixed during manufacturing, and the arm Even after repeated installation, the display unit 220, which overlaps the central part, suffers minimal damage.
[0153] Furthermore, if an active matrix display device is provided in the display unit 220, The display device has at least a layer containing transistors. The layer containing transistors is If the support structure 210 is simply attached and fixed to the curved surface, reliability is unlikely to decrease, The layer containing the lunger is bent and curved in one direction to form a concave surface, then returned to a flat surface, If you then repeatedly bend it in another direction to create a convex surface, the reliability will decrease. There is a risk. In that sense, the support structure 210 shown in Figure 7 is almost unchanged in the central part. Because it does not move, even if it does bend, by fixing it to the curved surface of the support structure 210, it will only bend in one direction. It can be configured to simply bend. That is, the support structure 210 is such that the display unit 220 bends It functions as a protective material to prevent excessive force or large torsional deformation.
[0154] As the material of the support structure 210, metal, resin, natural materials, etc. can be used. For weight reduction, it is preferable to make it thin. If metal is used as the material of the support structure 210, it is excellent in impact resistance, has high thermal conductivity, and is preferable. Also, if resin is used as the material of the support structure 210, weight reduction can be achieved and metal allergy will not occur. For weight reduction, it is preferable to make it thin. If metal is used as the material of the support structure 210, it is excellent in impact resistance, has high thermal conductivity, and is preferable.

The upper electrode 1435 is translucent and has an EL layer. It transmits the light emitted by 1433.
[0163] Furthermore, as shown in Figure 14(B), the EL layer consists of EL layer 1433A and EL layer 1433B. By using this method, the colors may differ from pixel to pixel. In that case, the emitted colors will be different. Therefore, in that case, the colored layer 1459, etc., does not necessarily have to be provided. good.
[0164] A colored layer 1459 is provided in a position that overlaps with the light-emitting element 1430, and overlaps with the insulating layer 1411. A light-shielding layer 1457 is provided at the position. The colored layer 1459 and the light-shielding layer 1457 are insulating. It is covered with layer 1461. The space between the light-emitting element 1430 and the insulating layer 1461 is sealed with a sealing layer 1413. It is filled.
[0165] The light-emitting panel has multiple transistors in the light extraction section 1304 and the drive circuit section 1306. It has a transistor 1440, which is provided on the insulating layer 1405. 05 and substrate 1401 are bonded together by adhesive layer 1403. Also, insulating layer 145 5 and substrate 1303 are bonded together by adhesive layer 1305. Insulating layer 1405 and insulating If a film with low water permeability is used for layer 1455, water will enter the light-emitting element 1430 and transistor 1440. This is preferable because it can suppress the intrusion of impurities such as [unclear], thereby increasing the reliability of the light-emitting panel. The bonding layer 1403 can be made of the same material as the adhesive layer 1305.
[0166] In specific example 1, an insulating layer 1405 and a transistor 1440 are fabricated on a heat-resistant substrate. The optical element 1430 is fabricated, the fabricated substrate is peeled off, and the adhesive layer 1403 is used on the substrate 1401. It can be fabricated by transposing the insulating layer 1405, the transistor 1440, and the light-emitting element 1430. This shows a light-emitting panel. In particular example 1, an insulating layer 14 is placed on a heat-resistant fabrication substrate. 55.

This shows a light-emitting panel that can be fabricated by inverting the shape.
[0167] When using a substrate made of a material with high water permeability and low heat resistance (such as resin), the substrate may be affected during the manufacturing process. Because high temperatures cannot be applied, the conditions for fabricating transistors and insulating films on the substrate are restricted. There are limitations. In the manufacturing method of this embodiment, the manufacturing of transistors and the like is done on a heat-resistant substrate. Because it is possible to manufacture transistors and form insulating films with sufficiently low water permeability, This can be done.

[0168] It is preferable to use materials with high toughness for substrates 1303 and 1401, respectively. This makes it possible to create a display device that is highly shock-resistant and less prone to damage. For example, a circuit board 1303 is an organic resin substrate, and substrate 1401 is a substrate using a thin metal material or alloy material. By using a plate, it is lighter and less prone to breakage compared to using a glass substrate. This makes it possible to create optical panels.
[0169] Metallic and alloy materials have high thermal conductivity and can easily conduct heat throughout the substrate, so light-emitting particles This is preferable as it can suppress the localized temperature rise of the flannel. The substrate thickness is preferably 10 μm to 200 μm, and 20 μm to 50 μm. It is preferable to do so.
[0170] Furthermore, if a material with high thermal emissivity is used for the substrate 1401, the surface temperature of the light-emitting panel will increase. This can suppress damage to the light-emitting panel and reduce its reliability. For example, substrate 140 1. A metal substrate and a layer with high thermal emissivity (for example, a metal oxide or ceramic material can be used) It can also be a laminated structure.
[0171] <Specific Example 2> Figure 11(A) shows another example of the light extraction section 1304 in the light-emitting panel.

[0181] Alternatively, a conductive layer that is electrically connected to the upper electrode 1435 may be provided on the insulating layer 1411. This configuration suppresses the voltage drop caused by the resistance of the upper electrode 1435. This is possible. If a paste (such as silver paste) is used as the material for the conductive layer, the conductive layer can be constructed. The metals that make up the layer aggregate into granular form. Therefore, the surface of the conductive layer has a rough and porous structure. As a result, the EL layer 1433 is difficult to cover the conductive layer, and the electrical relationship between the upper electrode and the conductive layer This makes it easier to establish connections, which is preferable.

[0223] First, a release layer 1503 is formed on the fabricated substrate 1501, and an insulating layer 14 is placed on the release layer 1503. 05 is formed. Next, multiple transistors are placed on the insulating layer 1405, a conductive layer 1357, and an insulating layer 1405. Layer 1407, insulating layer 1409, multiple light-emitting elements, and insulating layer 1411 are formed. Insulating layer 1411, insulating layer 1409, and insulating layer 1357 are exposed. 407 opens (see Figure 12(A)).
[0224] Furthermore, a release layer 1507 is formed on the fabricated substrate 1505, and an insulating layer 14 is placed on the release layer 1507. 55 is formed. Next, a light-shielding layer 1457, a colored layer 1459, and an insulating layer 1455 are formed on top of the insulating layer 1455. This forms the margin 1461 (see Figure 12(B)).
[0225] The fabricated substrates 1501 and 1505 are a glass substrate and a quartz substrate, respectively. Hard substrates such as sapphire substrates, ceramic substrates, and metal substrates can be used.
[0226] Furthermore, examples of glass substrates include aluminosilicate glass and aluminoborosilicate. Glass materials such as glass and barium borosilicate glass can be used. Subsequent heat treatment When the temperature is high, it is best to use materials with a strain point of 730°C or higher. In addition, crystallization gas You can use materials like lass.
[0227] When a glass substrate is used for the above-mentioned fabricated substrate, a silicon oxide film is placed between the fabricated substrate and the release layer. When insulating films such as silicon oxide nitride films, silicon nitride films, and silicon oxide nitride films are formed, This is preferable because it prevents contamination from the glass substrate.
[0228] Tungsten and molybdenum are used as the release layer 1503 and the release layer 1507, respectively. Titanium, tantalum, niobium, nickel, cobalt, zirconium, zinc, ruthenium, An element selected from rhodium, palladium, osmium, iridium, and silicon, said element It consists of an alloy material containing the element, or a compound material containing the element, and is a single layer or a laminated layer. The crystalline structure of the silicon-containing layer may be amorphous, microcrystalline, or polycrystalline.
[0229] The release layer can be formed by sputtering, plasma CVD, coating, printing, etc. The coating method includes spin coating, droplet dispensing, and dispensing.
[0230] If the delamination layer has a single-layer structure, it may consist of a tungsten layer, a molybdenum layer, or tungsten and molybdenum. It is preferable to form a layer containing a butene mixture. Alternatively, tungsten oxide or This is a layer containing oxidized nitride, a layer containing molybdenum oxide or oxidized nitride, or tang A layer containing an oxide or oxidized nitride of a mixture of stainless steel and molybdenum may be formed. Oh, a mixture of tungsten and molybdenum is, for example, an alloy of tungsten and molybdenum. It corresponds to this.
[0231] Furthermore, the release layer is a laminated structure consisting of a tungsten-containing layer and a tungsten oxide-containing layer. When forming the structure, a layer containing tungsten is formed, and an insulating layer formed of oxide is formed on top of it. By forming a film, the interface between the tungsten layer and the insulating film contains tungsten oxide. The formation of a layer may be utilized. Alternatively, the surface of the tungsten-containing layer may be subjected to thermal oxidation treatment. Treatments using oxygen plasma, nitrous oxide (N2O) plasma, ozonated water, etc., which have strong oxidizing properties. A layer containing tungsten oxide may be formed by treatment with a solution or other means. The processing and heat treatment may involve using oxygen, nitrogen, nitrous oxide alone, or a mixture of these gases with other gases. The procedure may be carried out in a gaseous atmosphere. The surface condition of the peeled layer is determined by the plasma treatment or heat treatment described above. By changing this, it is possible to control the adhesion between the release layer and the insulating film that is formed later. be.
[0232] The insulating layer may be a silicon nitride film, a silicon oxide nitride film, or silicon oxide nitride It is preferable to form the film, etc., in a single layer or multiple layers.
[0233] Each insulating layer is formed using methods such as sputtering, plasma CVD, coating, and printing. It is possible to achieve this, for example, by plasma CVD, where the film deposition temperature is 250°C or higher and 400°C or higher. By forming the film at temperatures below ℃, a dense film with very low water permeability can be created.
[0234] Subsequently, the surface of the fabricated substrate 1505 on which the colored layer 1459 etc. is provided or the fabricated substrate 1501 A material that will become the sealing layer 1413 is applied to the surface on which the light-emitting element 1430 etc. is provided, and the sealing layer 14 The surfaces are bonded together via 13 (see Figure 12(C)).
[0235] Then, the fabricated substrate 1501 is peeled off, and the exposed insulating layer 1405 and the substrate 1401 are bonded together. The layers are bonded using layer 1403. The fabricated substrate 1505 is then peeled off, revealing the exposed insulating layer 1 455 and substrate 1303 are bonded together using adhesive layer 1305. In Figure 13(A), Although the plate 1303 is configured so that it does not overlap with the conductive layer 1357, the conductive layer 1357 and the substrate 1303 It's okay if they overlap.
[0236] In addition, various peeling methods can be applied to the fabricated substrate in the peeling step according to one embodiment of the present invention. For example, if a layer containing a metal oxide film is formed on the side in contact with the layer to be peeled as the peeling layer, By weakening the metal oxide film through crystallization, the layer to be peeled off can be removed from the fabricated substrate. Furthermore, between the heat-resistant fabricated substrate and the layer to be peeled, an amorphous silicon containing hydrogen is used as the peeling layer. If a film is formed, the amorphous silicon film is removed by laser irradiation or etching. This allows the layer to be peeled off from the fabricated substrate. A layer containing a metal oxide film is formed on the side in contact with the metal, and the metal oxide film is weakened by crystallization, Furthermore, a portion of the peeled layer is etched using a solution or fluorine gas such as NF3, BrF3, or ClF3. After removal with a greaseproofing agent, it can be peeled off in the weakened metal oxide film. Furthermore, peeling A film containing nitrogen, oxygen, hydrogen, etc. as an abscission layer (for example, an amorphous silicon film containing hydrogen, a hydrogen-containing film) Using a gold film, an oxygen-containing alloy film, etc., the delamination layer is irradiated with laser light to remove the nitrogen contained within the delamination layer. Even when using a method that releases oxygen or hydrogen as gas to promote the separation of the layer to be peeled from the substrate, Good. Also, the fabricated substrate on which the peeled layer has formed can be mechanically removed or treated with a solution, NF3, BrF 3. Methods such as etching with a fluoride gas like ClF3 can be used to remove it. In this case, it is not necessary to provide a release layer.
[0237] Furthermore, by combining multiple of the above peeling methods, the peeling process can be performed more easily. In other words, irradiation with laser light, etching of the stripping layer with gas or solution, sharp knife or After mechanically removing the material with a scalpel or similar tool to make it easier to separate the peeled layer from the layer to be peeled, Furthermore, peeling can also be performed by physical force (such as by machinery). This process is described herein. This corresponds to the formation of the starting point for delamination. Processing is performed using a laminate manufacturing apparatus according to one aspect of the present invention. It is preferable that the construction member and the laminate have a starting point for the delamination.
[0238] Furthermore, by permeating the interface between the release layer and the layer to be released, the layer to be released is removed from the fabricated substrate. Alternatively, you can apply a liquid such as water while peeling.
[0239] As another peeling method, if the peeling layer is formed with tungsten, ammonia water and peroxide It is preferable to perform the stripping process while etching the stripping layer with a mixed solution of hydrogen oxide water.
[0240] Furthermore, if peeling is possible at the interface between the fabricated substrate and the peel-off layer, a peel-off layer may not be required. For example, glass is used as the fabrication substrate, and an organic resin such as polyimide is formed in contact with the glass. Then, insulating films, transistors, etc. are formed on the organic resin. In this case, the organic resin is heated. This allows for delamination at the interface between the fabricated substrate and the organic resin. Alternatively, the fabricated substrate and the organic resin can be separated. A metal layer is placed between the resins, and by passing an electric current through the metal layer, the metal layer is heated, and the metal layer and organic Delamination may be performed at the resin interface.
[0241] Finally, the conductive layer 1357 is exposed by opening the insulating layer 1455 and the sealing layer 1413. To release (see Figure 13(B)). Note that in the case where the substrate 1303 overlaps with the conductive layer 1357 In this case, the substrate 1303 and the adhesive layer 1305 are also opened (Figure 13(C)). The means of opening is special Not limited to, for example, laser ablation, etching, ion beam sputtering A cutting method or similar can be used. Alternatively, a sharp blade or similar tool can be used to cut into the film on the conductive layer 1357. You can also insert a needle and use physical force to peel off a portion of the membrane.
[0242] Based on the above, a light-emitting panel can be manufactured.
[0243] Furthermore, touch sensors or touch panels may be provided. For example, in Figure 10 Figure 15 shows an example where a touch panel 9999 is provided. The touch panel may be formed directly on the substrate 1303, or it may be formed on another substrate. You can place 9999 of them.
[0244] Although an example using a light-emitting element as the display element is shown here, the actual product of the present invention The implementation configuration is not limited to this. Various display elements can be used. Example For example, in this specification, etc., display element, display device having a display element, light-emitting element A light-emitting device, which is a device having a light-emitting element, can use various forms or various elements It may have children.

[0245] Furthermore, in this specification, etc., an active matrix system having an active element in the pixel, This allows for the use of a passive matrix system, which does not have active elements in the pixels.
[0246] In the active matrix system, the active elements (active elements, nonlinear elements) are, In addition to transistors, various active elements (active elements, nonlinear elements) can be used. This can be done. For example, MIM (Metal Insulator Metal), or T It is also possible to use elements such as FD (Thin Film Diode). Because it involves fewer manufacturing steps, it is possible to reduce manufacturing costs or improve yield. Alternatively, these elements can improve the aperture ratio due to their small size. This allows for lower power consumption and higher brightness.
[0247] Other than the active matrix method, there are active elements (active elements, nonlinear elements) It is also possible to use a passive matrix type that does not use active elements. Because it does not use sub-elements or nonlinear elements, the manufacturing process is simpler, resulting in reduced manufacturing costs or higher yield. This can improve the performance. Alternatively, active elements (active elements, nonlinear elements) can be used. Because it does not exist, the aperture ratio can be improved, leading to lower power consumption or higher brightness. It is possible.

Furthermore, even if the configuration includes a touch sensor, it is still composed of two circuit boards. This is possible. By minimizing the number of circuit boards, the light extraction efficiency and display clarity can be improved. Improvement becomes easier.
