DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following description, and it is understood by those skilled in the art that various changes can be made in form and detail. The present invention is not necessarily limited to the description of the following embodiments. The above statements are not to be construed as ... meaningless.
[0034] (Embodiment 1) An embodiment of a display device, a method for driving the display device, and a program will be described with reference to FIG. The display device described in the embodiment is, for example, a light-emitting device or a liquid crystal display device. For example, organic electroluminescent devices are included.
[0035] As shown in FIG. 1C, the display device 100 includes a display unit 120 and a detection unit 140. The display unit 120 includes a display surface 120a shown in FIG. 110a can be displayed.
[0036] The shape of the display device 100 is, for example, a ring formed by curving a belt-shaped structure. The device 100 may, for example, be at least partially flexible and have a gap 105. Therefore, the device can be worn on the wrist by moving the gap 105 to widen it. The device 100 can be worn not only on the wrist, but also on the neck, ankle, etc. The device 100 can be attached not only to the wrist, neck, or foot, but also to a columnar object such as a pipe or a pole. The cross section of the columnar object may be, for example, a circle or a polygon, but is not necessarily limited thereto. The device 100 can be mounted on more than just posts.
[0037] The display device 100 shown in FIG. 1 has a gap 105. 5. In other words, the display device 100 does not necessarily have a curved belt-shaped structure. The display device 100 can have a structure in which the display elements are connected without interruption. , it may have a structure that is commonly used in wristwatches.
[0038] The display device 100 is, for example, a ring-shaped display device. The display device 100 is a hollow columnar display device. The cross section of the display device 100 has a shape, for example, as shown in FIG. The annular display device can be made to have a continuous shape, as shown in FIG. It may also be formed with a slit as shown in A).
[0039] The display surface 120a can be displayed not only from the front as shown in FIG. 1(A) but also from the front as shown in FIG. The display surface 120a can extend to the outer peripheral surface on the opposite side. 00 circumferential direction, it can exist in a range of more than 180° but less than 360°. The display surface 120a is, for example, circumferentially arranged in a range of 360° along the circumferential direction of the display device 100. The display surface 120a may be arranged, for example, along the circumferential direction of the display device 100. The display surface 120a may be present on the entire surface of the display device 100 in the circumferential direction, for example. , can be present in an angular range greater than the viewing angle of the display device 100.
[0040] An image 110a can be displayed on the display surface 120a. For example, you can create objects that display a clock, weather, temperature, humidity, stock prices, and exchange rates. The object may be an icon or a widget. In addition to the objects, wallpaper can be displayed on the display surface 120a. In addition to the objects, operation buttons can be displayed on the display 20a. The button may be, for example, a button having a function of returning to the previous screen, a button having a function of displaying the home screen, or In place of the object, the wallpaper and the operation buttons are displayed. You can display the work button.
[0041] The 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 the display device 100 may include rotational position information of the display device 100. The rotational position information includes, for example, the direction of rotation of the display device 100 and the angle of rotation. The angle of rotation of the display device 100 is determined based on the inclination of the display device 100 before the rotation (for example, The inclination of the display device 100 in the state of FIG. 1(A) and the inclination of the display device 100 after rotation. The difference between the tilt angle and the tilt in the state shown in FIG. 1(B) can be used as the difference between the tilt angle and the tilt in the state shown in FIG. The standard for the 00 tilt (i.e., the position where the tilt of the display device is 0°) will be determined appropriately. The inclination of the display device 100 will be described later with reference to FIG.
[0043] The direction of rotation of the display device 100 is indicated by, for example, arrow 115a and arrow 115 in FIG. The direction of the arrow 115a is opposite to the direction of the arrow 115b. The direction of rotation of the display device 100 is indicated by, for example, arrow 115a and arrow 115 in FIG. The rotational position information of the display device 100 may include a direction perpendicular to the circumferential direction such as b. This may include the rate of rotation of the device 100 (ie, the angular velocity).
[0044] The detection means 140 is, for example, a detection means for detecting the inclination of the display device.
[0045] Using the detection means 140, position information based on the inclination of the display device 100 with respect to the vertical direction is detected. The vertical direction is the direction of gravity. It can also be expressed as the direction indicated by a string when the display device 100 is hung by the string. 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 intersecting with the device 100 and the center point is defined as the angle with respect to the vertical direction. It can be defined as the tilt of the display device 100.
[0046] The detection means 140 is, for example, an acceleration sensor or a gyro sensor.
[0047] The acceleration sensor is, for example, a two-axis acceleration sensor or a three-axis acceleration sensor.
[0048] The acceleration sensor may be a one-axis acceleration sensor.
[0049] A configuration in which a plurality of the acceleration sensors are provided to detect position information can be adopted. Cut.
[0050] The detection means 140 is a sensor that detects tilt other than an acceleration sensor or a gyro sensor. It is possible.
[0051] When an acceleration sensor is used as the detection means 140, for example, the detection means 140 is provided. The acceleration sensor detects the acceleration of gravity and can detect the tilt of the device. , the tilt of the device can be detected.
[0052] For example, when an acceleration sensor is provided on a substrate and the substrate is kept horizontal, The speed sensor detects a gravity force corresponding to +1g (g is the acceleration of gravity) in the downward direction (the direction of gravitational acceleration). When the acceleration sensor is held horizontally, the downward direction is the Z-axis direction. The directions perpendicular to the X-axis direction and the Y-axis direction are defined as the X-axis direction and the Y-axis direction. The orientation, Y-axis direction, and Z-axis direction change in response to a change in the inclination of the acceleration sensor.
[0053] When the acceleration sensor is provided on a substrate and the substrate is kept horizontal, the acceleration sensor detects an acceleration of +1g (g is the gravitational acceleration) in the Z-axis direction. or tilted 90° along the Y-axis, the acceleration sensor will be at 0g (g is the acceleration due to gravity) along the Z-axis. If you turn the board upside down (i.e., keep the board horizontal and the acceleration When the sensor is placed under the board, the acceleration sensor detects -1g in the Z-axis direction. Detects the acceleration of gravity (g).
[0054] Similarly, the acceleration sensor can detect acceleration in the X-axis direction. For example, when the substrate is kept horizontal, the acceleration sensor detects 0 g ( g is the acceleration of gravity). The board is rotated 90° around the Y axis of the acceleration sensor. When tilted (i.e., the acceleration sensor detects an acceleration of 0g (g is the acceleration of gravity) in the Y-axis direction), While maintaining the detection state, tilt the board by 90 degrees. In the X-axis direction, the acceleration sensor Detects acceleration of +1g (g is the acceleration due to gravity) or -1g (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 is When the camera rotates in the direction of the arrow and the acceleration sensor detects a negative acceleration in the X-axis direction, the display It may be defined that the device 100 has rotated in a negative direction.
[0055] FIG. 8 shows a cross-sectional view of a display device 100 provided with a detection means 140. For example, FIG. The rightward direction of the detection means 140 (here, the acceleration sensor) in (B) is the X-axis of the acceleration sensor. The left direction is the negative direction on the X-axis of the acceleration sensor. When the camera rotates from the state shown in Fig. 8(A) to the state shown in Fig. 8(B), the camera rotates to the state shown in Fig. 8(A). The inclination of the display device 100 in this state is an angle θ (θ is equal to or greater than −90° and less than 0°). The acceleration sensor detects a negative acceleration g·sinθ (arrow 145a) in the X-axis direction. This case can be defined as the display device 100 being rotated in the negative direction.
[0056] When rotating from the state of Fig. 8(B) to the state of Fig. 8(C), if the state of Fig. 8(B) is used as the reference, The display device 100 in FIG. 8C is inclined at an angle θ (θ is greater than 0° and less than or equal to 90°). At this time, the acceleration sensor detects a positive acceleration g sinθ (arrow 14) in the X-axis direction. 5b) is detected, and this case can be defined as the display device 100 rotating in the positive direction. do.
[0057] Similarly, the acceleration sensor can detect acceleration in the Y-axis direction as well.
[0058] When the display device 100 is in the state shown in FIG. 8(D) (for example, θ is greater than 90° and less than or equal to 180°), When the acceleration sensor detects a positive acceleration g sinθ( (θ is greater than 90° and less than 180°). Then, the state of Fig. 8(C) and Fig. 8(D) However, in this case, it may be difficult to distinguish between the two states in the Z-axis direction of the acceleration sensor. Considering this together with the detection results of the 100mW ... For example, in the state shown in FIG. 8(C), the acceleration sensor detects a positive acceleration in the Z-axis direction. This is because, in the state of FIG. 8(D), a negative acceleration is detected in the Z-axis direction.
[0059] Therefore, by providing an acceleration sensor in the display device 100, the tilt of the display device 100 can be detected. As a reference for the inclination of the display device 100, for example, the state of FIG. In this state, the tilt of the display device 100 can be regarded as 0°.
[0060] The tilt of the display device 100 having an acceleration sensor is detected by the acceleration sensor. The acceleration can be calculated using trigonometric functions. When the angle changes near -90°, the change in acceleration detected by the acceleration sensor is As a result, the sensitivity of the display device 100 to tilt is Therefore, multiple acceleration sensors are arranged at different positions on the display device 100 (for example, For example, the display device 100 may be moved to different positions so that multiple acceleration sensors detect different accelerations. When the acceleration sensors are placed at the same time, the inclination of all the acceleration sensors is close to 90° or -90°. Since it is not necessary to detect the acceleration of the tilt at the time, the tilt of the display device 100 can be detected with high accuracy. It can be put out.
[0061] The location information may include geographical location information. The geographical location information may be, for example, The location information is expressed as latitude and longitude coordinates. The geographic location information further includes height, In this case, the detection means 140 detects the geographical position information. In order to detect geographical location information, it is necessary to use, for example, a satellite positioning system. Specifically, the Global Positioning System (GPS) em) can be used.
[0062] FIG. 1A shows the display device 100 before it is rotated in the circumferential direction. FIG. 1B shows the display device 100 after it is rotated in the circumferential direction. 1 shows the display device 100 after it has been rotated in the direction indicated by the arrow 115b. When the display device 100 is fixed, the display device 100 moves in the circumferential direction (arrow 115b) (when a wristwatch is used as the display device 100, for example, When the wristwatch rotates around the arm in the direction of the arrow 115b, the wristwatch rotates as shown by the dotted line in FIG. 1(B). As shown, the display position of image 110a moves in the direction of arrow 115b relative to the line of sight. For example, in FIG. 1B, the image 110a moves from the front to the top of the display surface 120a. In addition, when the display device 100 is in a state where the image is more blurred than that shown in FIG. When the image 110a is rotated in the direction of the arrow 115b, the image 110a is displayed on the outer peripheral surface of the display surface 120a on the opposite side. It is difficult to move around and even see.
[0063] The annular display device 100 includes a detection means 140 for detecting position information of the display device, The display unit 120 displays an image at a display position determined based on the position information. This allows the image to be moved to a more easily visible position even if the display device 100 is moved. Preferably, the image is displayed in the same position as it was before the display device 100 was moved. It is possible.
[0064] The position information of the display device 100 is rotational position information based on the rotation of the display device 100 in the circumferential direction. In this case, the display position of the image may be determined based on the rotation of the display device 100 in the circumferential direction. The direction can be defined as moving in the opposite direction. For example, when the display device 100 is When the image is rotated in the direction of 115b, the display position of the image is changed to the arrow on the display surface 120a. Therefore, when the display device 100 is rotated, However, the image can be moved to a more visible position, preferably as shown in FIG. Thus, the image 110a moves to become the image 110b, and the display device 100 rotates in the circumferential direction. The image can be displayed in the same visible position before and after rotation. .
[0065] In addition, the display position of the image is moved on the display surface 120a, so that the liquid crystal element, the EL element, It is possible to suppress burn-in of the display unit 120 having a display element such as a display element. This can extend the life of the display device 100.
[0066] In addition, the display device 100 does not need to be provided with a mechanism for suppressing burn-in, such as a screen saver. Since burn-in of the display unit 120 can be suppressed even in the case of a single-mode display, the display device 100 can be made simpler. It can be configured as follows.
[0067] The detection means 140 may be a means for detecting the displacement of the display device 100. In this case, the method of driving the display device includes the steps of detecting a displacement of the annular display device, and and displaying the image at the display position. In addition, the driving method can be controlled by a program.
[0068] FIG. 2 shows a more detailed example of how to determine the display position of an image.
[0069] FIG. 2A shows a case where the cross section of the display device 100 is regarded as a circle.
[0070] In FIG. 2A, the cross section of the display device 100 is assumed to be a circle with a radius r (r>0). 1 shows the case where the display device 100 is rotated in the direction of the arrow 115b by an angle of θ radians (θ>0). At this time, the display position of the image is rotated in the opposite direction to the direction of rotation of the display device 100, that is, in the direction of the arrow. The distance traveled in the direction of the mark 115a is the product rθ of the angle and the radius. In FIG. 2A, image 110a moves in the direction of arrow 115a, and image 110b moves in the direction of arrow 115b. is displayed as:
[0071] FIG. 2A shows a case where the cross section of the display device 100 is considered to be a perfect circle. However, 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, it is possible to implement what is described in FIG. 2(A). In addition, even if the cross section of the display device 100 is not nearly a perfect circle, the cross section shown in FIG. By implementing the measures described in Figure 2(A), it is possible to achieve a more efficient You can move the image to a more visible position.
[0072] FIG. 2B shows a case where the cross section of the display device 100 is considered to be an ellipse. In B), the distance r (r>0) between the center of rotation and the display device 100 in the radial direction is not constant, but if you know the major and minor axes of the ellipse, the shape of the ellipse can be determined. The arc length of the ellipse corresponding to an angle θ radians (θ>0) of rotation of the device 100 is to be determined. Therefore, the length by which the display position is moved can be determined. Even if the image is considered to be an ellipse, it is possible to move the image to a position where it is more easily visible.
[0073] In FIG. 2C, the cross section of the display device 100 is considered to be an arbitrary curve including a closed curve. In FIG. 2C, the center of rotation and the display device 100 in the radial direction are The distance r (r>0) is not constant, but the distance r is a value f(θ ) before the display device 100 is rotated. The position where the image 110a is displayed is defined as an angle θ0 radian (θ0>0) on the display device 100. If the rotation angle is Δθ radians (Δθ>0), the distance to move the display position (along the arc) is The integral interval is [θ0, θ0+Δθ]. It can be expressed as a definite integral of f(θ) with respect to the variable θ.
[0074] Therefore, one aspect of the present invention can be implemented regardless of the shape of the cross section of the display device. can.
[0075] The display device 100 shown in FIG. 1A has a belt-shaped structure. In the figure, the image 110a moves to the image 110b along the longitudinal direction of the belt-shaped structure. For example, the display device 100 may have a strip-shaped structure. In response to the rotation of the object in the short direction, the display device 100 and the belt-shaped structure The display position of the image can be moved in the direction opposite to the direction of rotation of the object in the short dimension direction. In this case, the display surface 120a is extended so as to be curved in the short direction of the belt-shaped structure, for example. It is preferable that the image to be viewed is displayed on the back surface of the display surface 120a and on the display surface 120a. The display surface 120a is not a region where it is difficult to see, such as the side surface in the short length direction, but a region in front of the display surface 120a. It can be displayed in an area where it is easily visible.
[0076] In the above, an example in which the image is moved in the longitudinal direction of the belt-shaped structure, and an example in which the image is moved in the longitudinal direction of the belt-shaped structure The example of moving the structure in the short direction is shown, but these can be combined. You can also choose to do only one of them. You can also choose to do both by switching between them. It is also possible.
[0077] For example, if a wristwatch is used as the display device 100, the user may want to view the display on the wristwatch while lying down. For example, when standing, the display surface 120a that is visible when looking at the back of the hand may be When the user is lying down, the display area may look like that of Fig. 1(A). When viewing the display area of the display surface 120a that is visible when viewing the palm of the hand (for example, FIG. 1( D) may be seen as such.
[0078] As shown in FIG. 9, a camera unit 170 provided in the display device 100 is used to capture a picture of a user's face. and based on the position of the face in the captured image 180, the display position of the image can be determined. can.
[0079] FIG. 9A shows a case where the display device 100 is located below the face. For example, If you are wearing a watch on your wrist, make sure that the watch is below your face when you are standing. I often look at my watch while in this position.
[0080] In the state of FIG. 9(A), assume that the image you want to see is displayed in an easy-to-see position. In this state, when the face is captured using the camera unit 170, the face is captured in the captured image 18 as shown in FIG. Located above 0.
[0081] FIG. 9B shows a case where the display device 100 is located above the face. For example, If you are wearing a watch on your wrist, it may be above your face when you are sleeping. I often look at my watch while I'm in bed.
[0082] When the face is captured using the camera unit 170 in the state of FIG. 9(B), the result is as shown in FIG. 9(D). The face is located at the bottom of the captured image 180 .
[0083] The face position in FIG. 9(D) is located below the face position in FIG. 9(C). By moving the image on the display surface in the direction of the arrow 115c, the state shown in FIG. 9(B) is obtained. The image can be displayed at a position that is easy to see even if the viewer is not using the camera. can be expressed as a direction from top to bottom where the surface is directly visible.
[0084] A face in a captured image 180 when the display device 100 moves relative to the viewer The relationship between the magnitude and direction of the displacement of the position of the object and the length and direction of the image movement on the display surface is It is advisable to prepare in advance.
[0085] Furthermore, when the display device 100 moves relative to the viewer, the captured image 180 the size and direction of the displacement of the face position in the captured 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 image movement. When the distance between the viewer and the display device 100 changes, the area of the face in the captured image 180 changes. In addition, in the captured image 180 when the display device 100 moves relative to the viewer, Therefore, the amount of displacement of the face position in the captured image 180 changes. Using this relationship allows for more precise movement of the image on the display surface. do.
[0086] However, the relationship with the area of the face in the captured image 180 is not necessarily required. When a wearable device such as a wristwatch is used as the display device 100, It can be assumed that the distance of the display device 100 hardly changes.
[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. a first switch for capturing an image of the object to be captured using the camera unit when the object is in a positional relationship with the first switch; when the step, the display device, and the object to be imaged are in a second relative positional relationship, A second step of capturing an image of the target object using the camera unit; a part of the object to be imaged in a first image captured in the second step; the magnitude of displacement of the position of the part of the object to be imaged in the second image captured in the a third step of determining a display position of the image to be displayed on the display device based on the length and orientation of the image; In addition, the driving method of the display device can be implemented by a program. Can be controlled.
[0088] As exemplified above, when the display device 100 moves relative to the viewer, Even if the image is displayed on the screen, the image can be displayed at the desired position on the display screen. The display device 1 moves relative to the viewer with respect to the position of the face in the captured image 180. If the face position in the captured image 180 captured at 00 is located on the upper side, 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 is aligned with the arrow 115c or Even if the camera is rotated in the direction of the arrow 115d, the image you want to see is displayed in an easy-to-see position. In this case, the techniques described in this specification, such as those shown in FIG. 2 and FIG. 9, can be combined. Just match it up.
[0090] It is preferable to provide a plurality of camera units 170. In this way, the imaging range of one camera unit 1 Even if the face is located outside the camera 75, the face can be captured by other camera units. Therefore, the display position of the image on the display screen can be determined based on the position of the face in the captured image 180. can be determined.
[0091] The display surface 120a preferably has a curved surface.
[0092] In the case of the display surface 120a having a curved surface, the outer peripheral surface and the side surface on the opposite side of the display surface 120a are not visible. It is difficult to get the display screen 120a out of the front, not just the outer periphery or side of the opposite side. As the degree increases, the visibility decreases. By lowering the brightness, power consumption can be reduced.
[0093] For example, a tangent plane of a first display area on the display surface 120a and a tangent plane of a second display area When the angle between the first display area and the second display area is greater than 0 and is equal to or smaller than 180°, The luminance of the first display area can be reduced by a factor of 1. The angle of the tangent plane of the second display area is Here, the larger corner of the first display area and the second display area can be used. The regions are non-overlapping areas.
[0094] Here, the first display area is, for example, the front of the display surface 120a, and the second The display area is, for example, a side surface of the display surface 120a. The angle between the first display area and the tangent plane of the second display area is 90°, for example, when the first display area is The first display area is the front side, and the second display area is the side surface. The angle between the tangent plane of the first display area and the tangent plane of the second display area is 180°. In this case, the first display area is the front surface and the second display area is the outer peripheral 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. In this case, when the first display area is visible, the second display area is visible. Even this is difficult.
[0096] Therefore, for example, the tangent plane of the first display area and the tangent plane of the second display area are When the angle between the first display area and the second display area is greater than 0 and less than 90°, the luminance of the second display area is For example, the luminance of the first display area may be smaller than the luminance of the second display area. When the angle between the second display area and the tangent plane is 90° or more and 180° or less, the luminance of the first display area is made smaller than the luminance of the first display area, or The display of 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 displayed. When the viewing angle of the display device 100 is larger than 180° or less, the luminance of the second display area is The luminance of the first display area is made smaller than that of the first display area, or the display of the second display area is turned off. When the first display area is the front, the first display area The angle between the tangent plane of the second display area and the tangent plane of the second display area is 1 / 2 the viewing angle of the display device 100. When the angle is larger than 180° and is equal to or smaller than 180°, the luminance of the second display area is set to be larger than the luminance of the first display area. Alternatively, the display of the second display area can be turned off.
[0098] By adjusting the current flowing through the display element of the display unit 120 and the voltage applied thereto, the display surface 12 The brightness of 0a can be adjusted.
[0099] Devices that are intended to be carried around, such as wearable devices (e.g., wristwatches) As described above, when the display surface 120a is By reducing the brightness of the display portion or turning off the display, the power consumption of the display device 100 is reduced. In addition, the brightness of the display surface 120a can be reduced or the display By turning off the power, there is a synergistic effect that the life of the display device can be extended.
[0100] The display device 100 can be provided with a touch panel. This makes it possible to reduce the area for operation buttons on the display surface 120a. The display surface 120a can be enlarged, or the display device 100 can be made smaller. do.
[0101] The touch panel can detect operation information on the display surface 120a, and can display an image 1 The display position of the display screen 120a can be determined based on the operation information. The operation information may include a gesture of tracing a with a finger or a pen or a gesture of tapping on the display surface 120a. can be done.
[0102] For example, when the display surface 120a is pointed in the circumferential direction from top to bottom in FIG. By tracing with a pen or the like, the image 110a is moved in the direction of the arrow 115a on the display surface 120a. That is, by tracing the display surface 120a with a finger or a pen, the image 1 The display screen 10a can be scrolled in the direction of the arrow 115a in FIG. By tracing 20a with a finger or a pen, the display surface 120a is displayed on the opposite side as shown in FIG. The image displayed on the outer peripheral surface of the side is displayed in front of the display surface 120a as shown in FIG. , can be moved.
[0103] In the case of the annular display device 100 as shown in FIG. 1B, for example, When the display surface 120a is scrolled in the direction of the arrow, the image 110a is shifted to the direction of the arrow of the display surface 120a in FIG. Further, when the display surface 120a is scrolled in the direction of the arrow 115a, the image The image 110a is taken from the front as shown in FIG. 1B to the outer peripheral surface on the opposite side, that is, the outer peripheral surface of FIG. 1D. The display surface 120a is then moved to the bottom. The display surface 120a is then further scrubbed in the direction of the arrow 115a. When the image 110a is rolled, it moves to the top of the display surface 120a of FIG. 1(D) and further to the top of the display surface 120a. When the display surface 120a is scrolled in the direction of the arrow 115a, the display surface 120a of FIG. Image 110a appears from the top.
[0104] The above-mentioned scroll operation is performed when the display surface 120a rotates in a circumferential direction as shown in FIG. It can be used even if the display surface 120a is continuous in the circumferential direction. This can also be done while connected.
[0105] The image 110a does not fit in front of the display surface 120a shown in FIG. 1(A) and is displayed in the same direction as the image 110a shown in FIG. 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 image 110a is reduced in size by using the action of double tapping the image 110a as a trigger. can be done.
[0106] When reducing the size of the image 110a, the image 110a is reduced without changing its aspect ratio. This helps prevent image distortion.
[0107] As shown in FIG. 3A, 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. The storage medium 130 is a computer-readable storage medium. The detector 30 can be electrically connected to the detector 140 and the display unit 120. 40 and the display unit 120 can be electrically connected.
[0108] As shown in FIG. 3B, the storage medium 130 may be present outside the display device 100. In this case, the storage medium 130 is connected to the detection means 140 and the display device 100 via the terminal unit of the display device 100. The storage medium 130 can be electrically connected to the display unit 120. Alternatively, the storage medium 130 can be electrically connected to the detection means 1. 40 and the display unit 120 can be wirelessly connected. 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 connected by wires. By connecting the display device 100 without wires, it is possible to prevent poor contact. It can be categorized into types.
[0110] When the detection means 140 detects a displacement of the display device 100, the image is rewritten. If no displacement of the display device 100 is detected, the image is not rewritten, or A program for instructing the user to hold the image being displayed is stored in the storage medium 130. This makes it possible to reduce the power consumption required for rewriting an image.
[0111] Carrying the device away from a power source, such as a wearable device (e.g., a wristwatch) It is important to suppress power consumption in devices where this is expected. The above-mentioned configuration capable of suppressing power consumption is provided as a wearable device (e.g., a wristwatch). It is not applicable to devices that are expected to be disconnected from the power source and carried around, such as , which is more effective than applying it to devices that need to be plugged into a power source.
[0112] As shown in FIG. 3C, the display device 100 may include a battery 150. The battery 150 is, for example, a primary battery or a secondary battery. When the battery 50 includes a secondary battery, the battery 150 can be charged wirelessly. Alternatively, the display device 100 can be charged by connecting a power generating mechanism. The power generated by the power generating mechanism 160 is stored in the secondary battery. The power generation mechanism 160 may be, for example, a solar cell, a thermoelectric conversion element (for example, a thermocouple, The display device 100 is a wearable device such as a wristwatch. In this case, it is preferable to use a thermoelectric conversion element as the power generation mechanism 160. This is because For example, electricity can be generated continuously by the temperature difference between body temperature and the outside air temperature. The power mechanism 160 is not limited to this, and may be, for example, a device that converts the rotation energy of the display device 100 into electricity. The mechanism can be a mechanism for converting vibration energy into electricity or a mechanism for converting vibration energy into electricity. The mechanism for converting the rotational energy of the display device 100 into electric power converts the rotational energy of the display device 100 into electric power in response to the rotation of the display device 100. It can generate electricity and transmit the generated electricity to a secondary battery. A gyro sensor may be employed as the power generation mechanism 160 .
[0113] The display device 100 shifts the display position of the image when the display device is moved as described above. The display device moves in one mode, and the display device does not move in the other mode. It can be carried out.
[0114] FIG. 4 shows an example of a method for driving the display device 100. First, a step for specifying the display position of an image is performed. In step S110, when the display device 100 moves, the image is The display position of the image will be changed to a different mode.
[0115] The display position of the image can be preset or the display position of the image can be set to default. In these cases, step S110 can be omitted. The display device is already set to a mode in which the display position of the image moves when the display device moves. is preferred.
[0116] Next, the displacement of the display device 100 is detected (S120). If the displacement of the display device 100 is not detected, step S130 is performed. In this case, step S130 is not performed.
[0117] The displacement of the display device 100 includes a rotational displacement based on the rotation of the display device 100 in the circumferential direction. The rotational displacement may include, for example, a direction of rotation, an angle of rotation, and the like.
[0118] Instead of step S120, as shown in FIG. 5, the displacement of the display device 100 in the circumferential direction is A detecting step (S220) can be performed.
[0119] The circumferential displacement of the display device 100 is detected by a detection means such as an acceleration sensor or a gyro sensor. This can be detected by a step.
[0120] The acceleration sensor is, for example, a two-axis acceleration sensor or a three-axis acceleration sensor.
[0121] The acceleration sensor may be a one-axis acceleration sensor.
[0122] The displacement can be detected by a plurality of acceleration sensors.
[0123] Displacement is detected by a sensor that detects tilt other than an acceleration sensor or a gyro sensor. This can be done.
[0124] The displacement may include a geographic displacement. The geographic displacement may be, for example, a latitude and longitude. The displacement is expressed as a displacement on the coordinate system. The geographical displacement further includes a height coordinate. To detect geographical displacement, for example, a satellite positioning system, in particular a global positioning system, can be used. The global 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). For example, as shown in FIG. 5, the display position of the image is changed according to the amount of displacement of the display device 100. Alternatively, the step of moving in the opposite direction (S230) may be performed. The method described in part allows the display position of the image to be moved.
[0126] Next, it is determined whether the designation of the display position of the image has been released (S140). If it is determined that the designated position has been released, the display position of the image is adjusted when the display device moves. Exits the moving mode and switches to a mode in which the image display position does not move even if the display device moves. If it is not determined that the designation of the image display position has been released, step S1 is performed again. Do 20.
[0127] As described above, there is a mode in which the display position of the image is moved when the display device moves, and a mode in which the display device By switching to a mode where the image display position does not change even if the The power consumption can be reduced.
[0128] Carrying the device away from a power source, such as a wearable device (e.g., a wristwatch) It is important to suppress power consumption in devices where this is expected. The above-mentioned configuration capable of suppressing power consumption is provided as a wearable device (e.g., a wristwatch). It is not applicable to devices that are expected to be disconnected from the power source and carried around, such as , which is more effective than applying it to devices that need to be plugged into a power source.
[0129] When steps S120, S130, and S140 are repeated, the frequency of the repetition is appropriately set. For example, step S120 can be set to a value greater than 0 seconds and equal to or less than 1 / 60 seconds. Alternatively, in step S140, the display position of the image may be changed. After it is determined that the designation has not been released, the interval until step S120 is started is set to 0 It can be greater than a second and less than or equal to 1 / 60 of a second.
[0130] In step S110, for example, the image 110a displayed on the display surface 120a is touched. The trigger is to touch or approach the image 110a displayed on the display surface 120a. As a result, the display position of the image can be specified.
[0131] The display device 100 may be provided with a button for specifying the display position of the image. When touching or approaching the image 110a to specify the display position, This may cause the object to move, resulting in malfunction. The display device 100 is provided with a button for changing the settings, thereby reducing the possibility of malfunction. It is possible.
[0132] In step S110, for example, the display position of the image 110a is changed using a sound as a trigger. For example, by saying "specify display position", the image 110a You can specify the display position.
[0133] In step S110, for example, a tap, a double tap, a hold, a flick, a pick The trigger can be an action such as punching.
[0134] In step S110, for example, a motion of tracing the display surface 120a with a finger or a pen is performed. As a trigger, the user can specify the display position of the image. For example, the display surface 120a can be moved downward. You can trigger the trigger by swiping left and right. This is a gesture that resembles drawing a square. Swipe down on 120a, then swipe to the right, then swipe down again. You can also use the action of swiping down and then left to trigger the It can also be used as a trigger. It can be used in combination with one or more of the following directions: up, down, right, and left. You can also use gestures that combine diagonal directions. It can also be triggered by drawing a curved line such as a circle. The action of tracing 120a does not necessarily require contact with the display surface.
[0135] Swipe up or down may be used to scroll through images. Swipe right or left to move to adjacent viewing areas. Therefore, two directions selected from the directions such as up, down, right, and left are possible. If the trigger is continuous swiping in both directions, it must be distinguished from swiping in only one direction. This is preferable because it is possible to
[0136] A gesture is used as a trigger only while a button provided on the display device 100 is being pressed. You can set it by switching to this mode.
[0137] The methods described herein can be programmably controlled.
[0138] This embodiment may be combined with other embodiments and other aspects described herein. Cut.
[0139] (Embodiment 2) A method of displaying an image on the display surface 120a will be described with reference to FIG.
[0140] For example, objects that display clocks, weather, temperature, humidity, stock prices, exchange rates, etc. The object may be an icon or a widget. In addition to the objects, the display surface 120a may display wallpaper. In addition to the objects, operation buttons can be displayed on the display surface 120a. The operation button can be, for example, a button having a function of returning to the previous screen, a button for returning to the home screen, In addition, instead of the above objects, The wallpaper and the operation buttons can be displayed.
[0141] In this embodiment, an image is considered to be an object. It is also possible to replace the image with another image.
[0142] A plurality of objects can be displayed on the display surface 120a as shown in FIG. In particular, a plurality of objects are displayed in a visible area of the display surface 120a (for example, in front of the display surface 120a). Of course, the object can be displayed on the outer peripheral surface opposite to the display surface 120a. The project may be displayed.
[0143] As shown in FIG. 6A, the display surface 120a has a plurality of circumferential The display surface 12 can display objects so that a number of objects are arranged on the display surface 12. The number of objects displayed in 0a is not limited to three, but can be one, two, four or more. good.
[0144] As shown in FIG. 6B, the display surface 120a has a circumferential direction of the display device 100. Display objects so that they are aligned in a certain direction (for example, perpendicular to each other) The upper and lower parts of the display surface 120a may be difficult to see. As shown in Figure 6(B), by displaying objects, many objects become visible. The number of objects to be displayed on the display surface 120a can be reduced to two. There is no limitation, and it may be one or three or more.
[0145] As shown in FIG. 6C, the display surface 120a has a circumferential direction of the display device 100 and a A plurality of objects are arranged in a direction intersecting (for example, perpendicular to) the circumferential direction of the display device 100. Alternatively, the display surface 120a may display an object as if it were placed on the screen. The objects displayed on the display surface 120a can be displayed in a matrix. The number of kuts is not limited to six, but can be one, two, three, four, five, or even seven. More than that is fine.
[0146] The display device 100 can be equipped with a telephone function. A button for executing the above can be displayed on the display surface 120a.
[0147] The objects include, for example, clocks, weather, temperature, humidity, stock prices, exchange rates, maps, electronic money, Blood pressure, body temperature, and pulse. If the display device is a wearable device such as a wristwatch, It is preferable to display blood pressure, body temperature, pulse rate, etc. as objects. Pulse rate and other information can be monitored by measuring the blood pressure and body temperature of people and animals wearing wearable devices such as wristwatches. The following are not necessarily limited to temperature and pulse: For example, blood pressure, body temperature, etc. of people and animals in remote locations. It can also display your pulse rate.
[0148] When using weather as an object, you can display sunny, cloudy, rainy, etc. As for the weather, you can display the current weather at the time of checking the display, or you can display the weather forecast. The displayed weather shall be adapted to the location of the display device. In this case, in order to detect the geographical position information of the display device, for example, a satellite A star positioning system, specifically the Global Positioning Network, may be used.
[0149] This embodiment may be combined with other embodiments and other aspects described herein. Cut.
[0150] (Embodiment 3) In this embodiment, an example of a wrist-worn display device is shown. A perspective view of the display device is shown in FIG. vinegar.
[0151] As shown in FIG. 7, the display device 200 is a flexible display device on a curved surface of a support structure 210. The sensor 200 has a section 220.
[0152] The shape of the support structure 210 is a bracelet made by bending a belt-like structure. At least a part of 210 is flexible, and the gap 205 can be moved in a direction to widen the gap. Therefore, it can be worn on the wrist. The support structure 210 shown in FIG. 7 has a flexible end. The support structure is stable and has almost no fluctuation in the center, which is far from the ends. The curvature at the center of the body 210 remains the same as when it was attached and fixed at the time of production, and the curvature at the center of the body 210 remains the same as when it was attached to the arm. Even if the device is repeatedly attached, the display unit 220 overlapping the central portion is hardly damaged.
[0153] In addition, when an active matrix display device is provided in the display unit 220, The display device has at least a layer including a transistor. If the device is simply attached to the curved surface of the support structure 210 and fixed thereto, the reliability is unlikely to decrease. The layer containing the transistor is bent in one direction to create a concave surface, then returned to a flat surface, and If the plate is then bent in the other direction to make it convex, the reliability will decrease. In that sense, the support structure 210 shown in FIG. Since the support structure 210 is fixed to the curved surface, even if it does bend, it will only bend in one direction. That is, the support structure 210 can be configured so that the display unit 220 is only warped. It acts as a protective material to prevent excessive or large torsional deformation.
[0154] The material of the support structure 210 can be metal, resin, natural material, etc. Therefore, it is preferable to make the thickness small. If a metal is used as the material of the support structure 210, The support structure 210 is preferably made of resin, which has excellent impact resistance and high thermal conductivity. By using this material, it is possible to reduce the weight of the material and it does not cause metal allergies.
[0155] The shape of the display device shown in FIG. 7 is an example, and may be a belt or clasp for fixing to the wrist. Alternatively, a ring-shaped or cylindrical display device may be provided around the wrist.
[0156] In addition, although the example shows the device being worn on the wrist or upper arm, it may be worn on any part of the human body. For example, the device may be attached to the ankle. When the device is attached to the ankle, the device may be attached to the ankle as shown in FIG. It is sufficient to make the ankle support in a shape different from that of the ankle support and in a size that fits the shape of the ankle.
[0157] This embodiment may be combined with other embodiments and other aspects described herein. Cut.
[0158] (Embodiment 4) In this embodiment mode, an example of a flexible light-emitting device (light-emitting panel) will be described.
[0159] <Example 1> FIG. 10A shows a plan view of a flexible light-emitting panel. An example of a cross-sectional view between the chain lines G1-G2 is shown in FIG. 10(B). Another example of a cross-sectional view is shown in FIG. 4(A)(B).
[0160] The light-emitting panel shown in FIG. 10B includes an element layer 1301, an adhesive layer 1305, and a substrate 1303.

The element 1430 has a top emission structure. The upper electrode 1435 is transparent, and the EL layer It transmits the light emitted by 1433.
[0163] As shown in FIG. 14(B), the EL layer is an EL layer 1433A and an EL layer 1433B. In that case, the color of light emitted from each pixel may be different. In that case, the colored layer 1459 is not necessarily required. good.

The light emitting element 1430 is covered with a layer 1461. A sealing layer 1413 is provided between the light emitting element 1430 and the insulating layer 1461. It is filled.
[0165] The light emitting panel has a light extraction section 1304 and a driving circuit section 1306, and includes a plurality of transistors. The transistor 1440 is provided over an insulating layer 1405. The insulating layer 145 is bonded to the substrate 1401 by an adhesive layer 1403. 5 and the substrate 1303 are bonded together by an adhesive layer 1305. When a film with low water permeability is used for the layer 1455, water can be prevented from entering the light emitting element 1430 and the transistor 1440. This is preferable because it can suppress the intrusion of impurities such as ruthenium and zinc, thereby increasing the reliability of the light-emitting panel. The adhesive layer 1403 can be made of the same material as the adhesive layer 1305 .
[0166] In the specific example 1, the insulating layer 1405, the transistor 1440, and the light emitting device are formed on a highly heat-resistant substrate. An optical element 1430 is manufactured, the manufacturing substrate is peeled off, and the optical element 1430 is attached to the substrate 1401 using an adhesive layer 1403. The insulating layer 1405, the transistor 1440, and the light-emitting element 1430 can be transferred to the In the specific example 1, an insulating layer 14 is formed on a highly heat-resistant substrate. 55, a colored layer 1459 and a light-shielding layer 1457 are formed, the formed substrate is peeled off, and an adhesive layer 13 is formed. 05, an insulating layer 1455, a coloring layer 1459 and a light-shielding layer 1457 are formed on a substrate 1303. 1 shows a light-emitting panel that can be produced by transposing.
[0167] When using a material with high water permeability and low heat resistance (such as resin) for the substrate, Since high temperatures cannot be applied, the conditions for fabricating transistors and insulating films on the substrate are limited. In the manufacturing method of this embodiment, transistors and the like are fabricated on a highly heat-resistant fabrication substrate. This allows the formation of highly reliable transistors and insulating films with sufficiently low water permeability. By transferring them to the substrate 1303 or 1401, the reliability can be improved. Thus, in one embodiment of the present invention, a light-weight or thin light-emitting panel can be manufactured.

[0168] It is preferable to use a highly tough material for the substrate 1303 and the substrate 1401. This makes it possible to realize a display device that is highly impact resistant and difficult to break. The substrate 1303 is an organic resin substrate, and the substrate 1401 is a substrate made of a thin metal material or alloy material. By using a plate as the substrate, it is lighter and less likely to break than when a glass substrate is used. Light panels can be realized.
[0169] Metallic and alloy materials have high thermal conductivity and can easily conduct heat across the entire substrate, making it possible to This is preferable because it can suppress local temperature rises in the panel. The thickness of the substrate is preferably 10 μm or more and 200 μm or less, and more preferably 20 μm or more and 50 μm or less. It is more preferable to do so.
[0170] In addition, if a material with high thermal emissivity is used for the substrate 1401, the surface temperature of the light-emitting panel will become high. This can prevent the light-emitting panel from being damaged or the reliability from being reduced. 1 can be made by using a metal substrate and a layer with high thermal emissivity (e.g., metal oxide or ceramic material). A laminated structure of the above may also be used.

[0181] In addition, a conductive layer electrically connected to the upper electrode 1435 may be provided on the insulating layer 1411. With this configuration, the voltage drop caused by the resistance of the upper electrode 1435 is suppressed. When a paste (such as silver paste) is used as the material for the conductive layer, the conductive layer can be formed. The metal that forms the conductive layer becomes granular and aggregates. This results in a structure in which the surface of the conductive layer is rough and has many gaps. Therefore, it is difficult for the EL layer 1433 to cover the conductive layer, and electrical connection between the upper electrode and the conductive layer is not possible. This is preferable because it makes it easier to establish a connection.

[0234] Thereafter, the surface of the preparation substrate 1505 on which the colored layer 1459 and the like are provided or the preparation substrate 1501 A material for forming a sealing layer 1413 is applied to the surface on which the light emitting element 1430 and the like are provided, and the sealing layer 14 The surfaces are attached to each other via 13 (see FIG. 12(C)).
[0235] Then, the fabrication substrate 1501 is peeled off, and the exposed insulating layer 1405 and the substrate 1401 are bonded together. The insulating layer 1403 is used for bonding. The fabrication substrate 1505 is peeled off, and the exposed insulating layer 1 455 and a substrate 1303 are attached to each other using an adhesive layer 1305. The plate 1303 is configured not to overlap the conductive layer 1357. may overlap.
[0236] Note that in the peeling step of one embodiment of the present invention, various peeling methods can be applied to the formation substrate. For example, when a layer containing a metal oxide film is formed as a peeling layer on the side in contact with the layer to be peeled off, The metal oxide film is weakened by crystallization, and the layer to be peeled off can be peeled off from the substrate. In addition, a hydrogen-containing amorphous silicon layer is formed between the heat-resistant substrate and the layer to be peeled off. If a film is formed, the amorphous silicon film is removed by irradiation with laser light or etching. In this way, the layer to be peeled off can be peeled off from the formation substrate. a layer including a metal oxide film is formed on the side in contact with the metal oxide film, and the metal oxide film is weakened by crystallization, and Furthermore, a part of the peeling layer is etched using a solution or a fluoride gas such as NF3, BrF3, or ClF3. After removal by welding, the weakened metal oxide film can be peeled off. Films containing nitrogen, oxygen, hydrogen, etc. as delamination layers (e.g., amorphous silicon films containing hydrogen, hydrogen-containing alloys, etc.) The peeling layer is irradiated with laser light to remove the nitrogen contained in the peeling layer. Alternatively, a method may be used in which oxygen or hydrogen is released as a gas to promote peeling between the layer to be peeled and the substrate. In addition, the substrate on which the peeled layer is formed can be mechanically removed or the peeled layer can be removed by removing the peeled layer from the substrate using a solvent such as NF3, BrF 3. A method of removing the film by etching with a fluoride gas such as ClF3 can be used. In this case, the release layer does not need to be provided.
[0237] In addition, the peeling process can be performed more easily by combining a plurality of the above peeling methods. In other words, laser irradiation, etching of the peeling layer with gas or solution, sharp knife or Mechanical removal is performed using a scalpel or similar tool to make the peeling layer and the layer to be peeled easier to peel off. Alternatively, the peeling can be performed by physical force (mechanically, etc.). This corresponds to the formation of the starting point of peeling in the laminate manufacturing apparatus according to one embodiment of the present invention. It is preferable that the construction member and the laminate have a starting point for the peeling formed therein.
[0238] In addition, a liquid is permeated into the interface between the release layer and the layer to be peeled off, and the layer to be peeled off is peeled off from the substrate. Also, the peeling may be performed while pouring liquid such as water on the film.
[0239] As another peeling method, when the peeling layer is made of tungsten, it is The peeling layer may be etched with a mixed solution of hydrogen oxide and water to perform the peeling.
[0240] In addition, if peeling can be performed at the interface between the preparation substrate and the layer to be peeled off, a peeling layer may not be provided. For example, glass is used as the substrate, and an organic resin such as polyimide is formed on the glass. Then, an insulating film, a transistor, etc. are formed on the organic resin. In this case, the organic resin is heated. This allows the substrate to be peeled off at the interface between the substrate and the organic resin. A metal layer is placed between the resin and the metal layer is heated by passing an electric current through the metal layer, and the metal layer and the organic Peeling may occur at the resin interface.
[0241] Finally, the insulating layer 1455 and the sealing layer 1413 are opened to expose the conductive layer 1357. 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 (FIG. 13(C)). However, the present invention is not limited to the above, and examples thereof include laser ablation, etching, and ion beam sputtering. Alternatively, a film on the conductive layer 1357 may be cut with a sharp blade or the like. Alternatively, a scratch may be applied and a portion of the membrane may be peeled off using physical force.
[0242] In this manner, a light-emitting panel can be manufactured.
[0243] A touch sensor or a touch panel may be provided. For example, in FIG. FIG. 15 shows an example in which a touch panel 9999 is provided. The touch panel may be formed directly on the substrate 1303 or on a separate substrate. You may also place 9999.
[0244] In this embodiment, a light-emitting element is used as a display element. One embodiment is not limited to this. Various display elements can be used.

[0246] In the active matrix method, a transistor is used as an active element (active element, nonlinear element). By using not only transistors but also various active elements (active elements, nonlinear elements), For example, MIM (Metal Insulator Metal) or T It is also possible to use FD (Thin Film Diode) and other elements. Since the number of manufacturing steps is small, it is possible to reduce manufacturing costs and improve yields. Alternatively, these elements can improve the aperture ratio due to their small size. This makes it possible to achieve low power consumption and high brightness.
[0247] As a non-active matrix type, active elements (active elements, nonlinear elements It is also possible to use a passive matrix type that does not use active elements. Since it does not use any nonlinear elements, there are fewer manufacturing steps, which reduces manufacturing costs and improves yield. It is possible to improve the accuracy. Or, it is possible to use active elements (active elements, nonlinear elements) Since the aperture ratio is not increased, it is possible to achieve low power consumption and high brightness.
