  As described above, the display unit 10 of the electronic device 1 according to the embodiment includes the display 11, the microlens array 12, and the touch sensor 13.

  The display 11 has a light emission surface 11a at the upper side in FIG. The light emission surface 11 a includes a plurality of pixels.

  The microlenses 30 are arranged in a predetermined array on the microlens array 12.

  The microlens array 12 is positioned to face the light emission surface 11 a of the display 11. The microlens 30 has, for example, a convex shape that protrudes toward the light emission side of the display 11.

  In FIG. 3, the microlens array 12 directly overlaps the display 11. Also, the touch sensor 13 overlaps the display 11 via the microlens array 12.

  The overlapping of the display 11 and the microlens array 12 or the touch sensor 13 may mean that the display 11 and the microlens array 12 or the touch sensor 13 overlap perpendicularly to the respective surfaces. In other words, the overlapping of the display 11 and the microlens array 12 or the touch sensor 13 may be overlapping of the display 11 and the microlens array 12 or the touch sensor 13 in the thickness direction of each panel.

  The display unit 10 may include predetermined panels other than the display 11, the microlens array 12, and the touch sensor 13. A predetermined panel may be interposed between the display 11 and the microlens array 12. The panel may be interposed between the microlens array 12 and the touch sensor 13.

  Although the display 11 and the touch sensor 13 are separated in FIG. 3, the touch sensor 13 may be integrated with the display 11. The display in which the touch sensor 13 and the display 11 are integrated is, for example, an in-cell display or an on-cell display.

  The microlens array 12 may be disposed inside the display 11. The display 11 includes, for example, a color filter inside. At this time, a glass substrate or a polarizing plate may be disposed on the light emission side of the color filter. Here, the microlens array 12 may be disposed between the color filter and the glass substrate in one embodiment. In one embodiment, the microlens array 12 may be disposed between the color filter and the polarizer. In one embodiment, the microlens array 12 may be disposed between the polarizing plate and the glass substrate. The microlens array 12 may be disposed on the light exit side of the color filter. As a result, the color filter and the microlens array 12 can be accurately aligned, and thus a clear image can be displayed on the display unit 10.

  FIG. 4 is a first example of a plan view of the display unit 10 according to an embodiment. Only a portion of the display unit 10 is shown in the figure for simplicity.

  In FIG. 4, a square portion surrounding a circle indicates the microlens 30. As shown in FIG. 5, a plurality of microlenses 30 are disposed to face the light emission surface 11a. The light emission surface 11a of the display 11 included in the display unit 10 has a first area 111a and a second area 112a. The first area 111a is an area indicated by oblique lines in FIG. The second area 112 a is an area other than the hatched area. The microlens 30 is positioned to face the first area 111 a of the first area 111 a and the second area 112 a. The microlenses 30 are disposed to face each other in the first region 111a, and the microlenses 30 are not disposed to face each other in the second region 112a. In FIG. 5, the first region 111 a includes thirteen microlenses 30.

  In FIG. 5, the positional relationship between the microlenses 30 is shown. In FIG. 5, only a portion of the display unit 10 is shown for simplicity.

  The first distance L1 from the center point of the micro lens 30 to the center point of another micro lens 30 located closest to the micro lens 30 is twice the distance from the predetermined side of the micro lens 30 to the center point It may be larger than the second distance L2. In other words, the first region 111a described above includes a plurality of regions (that is, the plurality of microlenses 30), and is one of the plurality of regions from the center point of the third region which is one of the plurality of regions. The first distance L1 to the center point of the fourth area located closest to the three areas may be larger than the second distance L2 which is twice the distance from the end of the third area to the center point of the third area . Further, the plurality of regions (that is, the plurality of microlenses 30) may be arranged at equal intervals in a predetermined direction. In FIG. 5, the plurality of microlenses 30 are arranged at equal intervals in the vertical direction, the horizontal direction, and the diagonal direction of the square.

  The plurality of microlenses 30 may be arranged in a checkered flag, as shown in FIGS. 4 and 5. In the checkered flag arrangement, the first area 111a and the second area 112a are alternately arranged in both the vertical direction and the horizontal direction in FIGS. 4 and 5. The checkered flag-like arrangement is one of the arrangements that satisfy the distance between the microlenses 30 and the arrangement thereof described above.

  The plurality of microlenses 30 may be spaced apart without contacting at points or lines.

  The microlens array 12 may be configured by arranging a plurality of microlenses 30 on a glass substrate. In this case, flat glass is present in the second region 112a. In addition, the microlens array 12 may be configured by bonding predetermined points at the ends of the plurality of microlenses 30 or a part of the sides. In this case, no object exists in the second area 112a.

  The microlens 30 is not limited to a quadrangle in plan view, and may be any polygon such as a triangle, a pentagon, or a hexagon. The microlenses 30 may be circular.

  FIG. 6 is a second example of a plan view of the display unit 10 according to an embodiment. Only a portion of the display unit 10 is shown in the figure for simplicity.

  In FIG. 6, the shaded area is the first area 111a of the light emission surface 11a. Further, the area other than the hatched area is the second area 112 a of the light emission surface.

  FIG. 7 is a third example of a plan view of the display unit 10 according to an embodiment. Only a portion of the display unit 10 is shown in the figure for simplicity.

  In FIG. 7, the hatched area is the first area 111 a of the light emission surface 11 a. Further, the area other than the hatched area is the second area 112 a of the light emission surface.

  FIG. 8 is a view showing the relationship between the display unit 10 according to an embodiment, light emitted from the display unit, and the human pupil 50. As shown in FIG.

  The display 11 has a light emission surface 11a, and displays an image by emitting light from the light emission surface 11a. The pupil 50 is the pupil of the user's eye observing the image displayed on the display 11. The light incident on the pupil 50 is projected onto the retina 50b via the lens 50a to form an image. Thereby, the user can recognize the image displayed on the display 11.

  The light emitted from the light emission surface 11a is diffused light. The micro lens 30 has an arbitrary focal length and reduces the diffusion degree of the diffused light to be transmitted. Specifically, for example, when the micro lens 30 is disposed at a position away from the light emission surface 11 a of the display 11 by a distance close to the focal distance of the micro lens 30, a specific light emission point of the light emission surface 11 a The light emitted from the light source is collimated as it passes through the microlens array 12. That is, the light passing through the microlens array 12 is focused so as to be parallel light beams. Therefore, the display unit 10 in which the microlens array 12 is arranged can display an image with a deeper focal depth than a display unit in which the diffused light emitted from the light emission surface 11 a is directly incident on the pupil 50. Also, after passing through the pupil 50, parallel light passing through the microlens array 12 forms an image at a shorter distance than diffused light. Therefore, even if the refractive power of the lens 50a is weak, that is, even if a refractive error such as presbyopia or myopia occurs in the user's pupil, the display unit 10 can display an image that the user can easily focus on. Focusing means that the light passing through the lens 50a is imaged in the vicinity of the retina 50b. The distance between the light emission surface 11 a and the microlens 30 may be within ± 10% of the focal length of the microlens 30. As a result, the light having passed through the microlens 30 can be easily focused within the desired range at the observation position.

  Parallel light emerging from a particular light exit point and passing through the microlens array 12 may have any length. For example, since the pupil diameter of a human being is about 2 mm in the bright place, in order to be incident on the pupil 50, the path of the parallel light may be about 2 mm or less. Also, the parallel light passing through the microlens array 12 has a diameter approximately equal to the diameter of the microlens 30. Therefore, the diameter of the microlens 30 may also have an arbitrary value, but the diameter may be about 2 mm or less, as with parallel light having passed through the microlens array 12.

  Diffuse light is emitted from the light emission surface 11a as described above. Thus, light emitted from a predetermined point on the light emission surface 11 a can illuminate the plurality of microlenses 30 included in the microlens array 12. As a result, a part of the diffused light from the predetermined point may pass through a certain microlens 30 and be collimated to enter the pupil 50. Further, the other part of the diffused light from the predetermined point may pass through another micro lens 30, be collimated, and be guided away from the pupil 50.

  When the entire light emission surface 11 a emits light, a plurality of light beams enter the pupil 50. Then, when a plurality of light beams enter the pupil 50, the depth of field becomes shallow. Therefore, the number of incident light beams may be controlled by emitting light from a part of the light emission surface 11 a so that the depth of field is not extremely shallow. To allow light to be emitted from a part of the light emission surface 11a may be to provide a light emission point. The light emission point may be, for example, one per pixel. At this time, the distance between the light emission points, the distance between the light emission points, and the distance between the parallel light beams emitted from the light emission point and passing through the microlens 30 may be any value.

  FIG. 9 is an exploded perspective view showing the positional relationship between the display 11 and the microlens array 12 in the display unit 10 according to an embodiment. In FIG. 9, only a portion of the display unit 10 is shown for simplicity. FIG. 10 is a view showing a pixel 100 included in the display unit 10.

  The image displayed on the display 11 is composed of a plurality of pixels 100 included in the light emission surface 11 a. That is, the display 11 performs display by emitting diffused light from the light emission surface 11 a having the plurality of pixels 100. The display 11 shown in FIG. 9 includes 5 × 5 pixels 100.

  As shown in FIG. 10, the pixel 100 may include one type of sub-pixel for each of the three primary colors. The pixel 100 includes a red pixel 100a, a green pixel 100b, and a blue pixel 100c. The red pixel 100a is a red sub-pixel. The green pixel 100b is a green sub-pixel. The blue pixel 100c is a blue sub-pixel. In FIG. 10, the red pixel 100a, the green pixel 100b, and the blue pixel 100c are arranged in a stripe, but the present invention is not limited to this, and they may be arranged in an arbitrary form and in order.

  As shown in FIG. 9, a mask 60 having a plurality of openings may overlap with the display 11. As a result, the light emitted from the light emission surface 11 a of the display 11 and incident on the microlens array 12 is limited. The mask 60 has a plurality of light emission points 60a. The mask 60 is bonded to the display 11 directly or indirectly. The mask 60 may not be disposed. That is, the display unit 10 may be configured such that all the light emitted from the light emission surface 11 a is incident on the microlens array 12.

  In FIG. 9, the microlens 30 has a size corresponding to one pixel 100 among the plurality of pixels 100 included in the display 11. However, the positional relationship between the display 11 and the microlens array 12 described in FIG. 9 is only an embodiment, and for example, a plurality of microlenses 30 may be opposed to one pixel 100. Alternatively, one microlens 30 may be opposed to a plurality of pixels 100.

  Further, in FIG. 9, one pixel 100 is disposed for a plurality of light emission points 60a. However, the light emission point 60a of the display 11 described in FIG. 9 is only one embodiment, and one light emission point 60a may be disposed in one pixel 100, for example. When one light emission point 60a is disposed in one pixel 100, light emitted from one pixel 100 may be configured to be incident on one light emission point 60a. Also, each sub-pixel may have one light emission point 60a.

  The image displayed on the display unit 10 will be described with reference to FIGS. 11 and 12. 11 and 12 show only a portion of the display unit 10 for the sake of simplicity.

  The display 11 of the display unit 10 shown in FIGS. 11 and 12 includes 9 × 9 pixels 100. The microlenses 30 of the display unit 10 shown in FIGS. 11 and 12 are arranged in a checkered flag, as in FIGS. 4 and 5.

  The controller 27 can determine whether to emit light for each of the plurality of pixels 100 included in the display unit 10. In addition, the controller 27 can control the amount of light emitted for each of the plurality of pixels 100 included in the display unit 10.

  In FIGS. 11 and 12, a plurality of microlenses 30 are disposed to face each other in the first area 111a of the light emission surface 11a. Moreover, the micro lens 30 is not arrange | positioned facing the 2nd area | region 112a of the light emission surface 11a.

  FIG. 11 shows a first example of an image displayed on the display unit 10 in the first display mode.

  In FIG. 11, a diamond-shaped image is displayed on the display unit 10, and no image is displayed in parts other than the diamond shape. At this time, the controller 27 displays a diamond-shaped image on the display unit 10, and performs display processing in which the image is not displayed on parts other than the diamond shape. It should be noted that "display processing" includes not displaying an image in parts other than the diamond shape. Note that not displaying an image may be, for example, displaying black.

  In FIG. 11, the entire first region 111a of the light emission surface 11a in which the plurality of microlenses 30 are disposed opposite to each other, and the entire second region 112a of the light emission surface 11a in which the microlenses 30 are not disposed opposite to each other. Display processing is performed on both sides. In other words, the controller 27 executes display processing in both the entire first area 111a and the entire second area 112a. In the first display mode, display is performed in at least a part of the second area 112a. In the first display mode, in one embodiment, the display process is performed on the entire second area 112a, and the area where the display process is performed in the first area 111a is less than the area where the display is performed in the second area 112a. I hope there is. In the first display mode, in one embodiment, the display process is performed on the entire second area 112a, and the display process may not be performed on the first area 111a. In other words, in the first display mode, the proportion of substantially parallel light emitted from the first area 111a may be equal to or less than the proportion of diffused light emitted from the second area 112a.

  FIG. 12 shows a second example of the image displayed on the display unit 10 in the second display mode.

  In FIG. 12, the display processing is performed on the entire first region 111a of the light emission surface 11a in which the microlenses 30 are disposed opposite to each other, and the second region of the light emission surface 11a in which the microlenses 30 are not disposed opposite to each other. Display processing is not performed at 112a. In other words, the controller 27 performs the display process on the entire first area 111a, and does not execute the display process on the second area 112a. In the second display mode, the area in which the display processing is performed is larger in the first area 111a than in the first display mode. In the second display mode, in one embodiment, the display process is performed in at least a part of the first area 111a, and the display process is performed in the second area 112a in the first area 111a. It should be larger than the area. In other words, in the second display mode, the proportion of substantially parallel light emitted from the first area 111a may be larger than the proportion of diffused light emitted from the second area 112a.

  In the first display mode or the second display mode, the fact that the controller 27 does not execute the display process may perform the display process with a smaller amount of light than the area where the display process is executed.

  The first display mode and the second display mode may be performed in consideration of ambient brightness. For example, when the surroundings of the user are bright, the pupil diameter of the user is smaller than when the surroundings are dark. Therefore, when the surrounding environment is bright, the depth of field of the user's pupil is deep, and even if refraction error occurs in the user's pupil, the possibility of focusing can be enhanced compared to when the environment is dark. . In addition, for example, when the environment around the user is dark, the pupil diameter of the user is larger than when the environment is bright. Therefore, when the surrounding environment is dark, the depth of field of the user's pupil is shallow, and when refraction error occurs in the user's pupil, there is a high possibility that focusing can not be performed as compared with a bright environment. .

  A user with a refractive error in the pupil is more likely to be able to focus when the environment is bright, even if light from the first region 111a from which substantially parallel light is emitted is not emitted . In addition, when a user has a refractive error in the pupil, if the surroundings are bright, the light from the second area 112a from which the diffused light is emitted is the light from the first area 111a from which the light having a substantially parallel light quantity is emitted. Even if it is more than the amount of light, the possibility of focusing can be increased. Thus, the first display mode may be performed when it is estimated that the environment around the user is bright. For example, the controller 27 may execute the first display mode at a preset time such as 6 o'clock to 17 o'clock. Thus, the estimation that the environment around the user is bright is performed, for example, by time. The morning or daytime is likely to be brighter around the user than at night. The controller 27 may execute the first display mode when the detection result of the illuminance sensor 24 is equal to or greater than a predetermined value. When the controller 27 determines the brightness around the user based on the detection result of the illuminance sensor 24, it can be estimated that the surrounding environment is bright even in the room regardless of day and night. In addition, the diameter of the human pupil is smaller in a bright place than in a dark place and larger in a dark place than in the bright place. Therefore, the controller 27 measures the pupil diameter of the user with the camera 23 and the measured pupil The first display mode may be executed when the distance is equal to or less than a predetermined value. The estimation of the brightness by the time, the estimation of the brightness by the illuminance sensor 24, and the estimation of the brightness by the measured pupil diameter may be performed in combination as appropriate.

  A user having a refractive error in the pupil is likely to be unable to focus when light is not emitted from the first region 111a from which substantially parallel light is emitted, when the environment is dark. In addition, when a user has a refractive error in the pupil, if the surrounding area is dark, the light from the second area 112a from which diffused light is emitted is the light from the first area 111a from which light having substantially parallel light quantity is emitted. If the amount is larger than the amount of light, the possibility of being unable to focus increases. Thus, the second display mode may be performed when it is estimated that the user's surroundings are dark. For example, the controller 27 may execute the second display mode at a preset time such as 17 o'clock to 6 o'clock. Thus, the estimation that the environment around the user is dark is performed, for example, by time. At night, the surroundings of the user are likely to be dark compared to morning or daytime. The controller 27 may execute the first display mode when the detection result of the illuminance sensor 24 is less than a predetermined value. When the controller 27 determines the brightness around the user based on the detection result of the illuminance sensor 24, it can be estimated that the surrounding environment is dark also in the room regardless of day and night. Further, the controller 27 may measure the pupil diameter of the user by the camera 23 and execute the second display mode when the measured pupil diameter is equal to or more than a predetermined value. The estimation of the brightness by the time, the estimation of the brightness by the illuminance sensor 24, and the estimation of the brightness by the measured pupil diameter may be performed in combination as appropriate.

  In the above embodiment, in the dark place where the user who has ametropia in the pupil is less likely to focus the image than in the bright place, the second mode has a higher proportion of parallel light than the first mode. And a user with refractive error in the pupil can display an image that is easy to focus. Further, in the above-described embodiment, the second display mode in which the ratio of parallel light is larger than that of diffused light can be performed, and a user who has a refractive error in the pupil can display an image that is easy to focus. In the above-described embodiment, by performing display processing in both the first area 111a and the second area 112a, a user who has a refractive error in the pupil can display an image that is easy to focus on. It is possible to display an image with a wider viewing angle than with light alone. In the above-described embodiment, by performing display processing in both the first area 111a and the second area 112a, a user who has a refractive error in the pupil can display an image that is easy to focus on. It is possible to display an image brighter or resolution higher than that of light alone. Therefore, the visibility of the image displayed on the electronic device 1 is improved.

  In the above embodiment, the first display mode for emitting only the diffused light is performed in the bright place where the user who has a refractive error in the pupil is more likely to focus the image than in the dark place, It is possible to display an image with a wider viewing angle than in the second display mode. In the above-described embodiment, the ratio of diffused light is larger than that of parallel light in a bright place where a user who has a refractive error in the pupil is more likely to focus an image than in a dark place. The display mode can be executed to display an image having a wider viewing angle than the second display mode. In the above-described embodiment, by performing display processing in both the first area 111a and the second area 112a, it is possible to display an image brighter or higher in resolution than in the case of only diffused light. Therefore, the visibility of the image displayed on the electronic device 1 is improved.

  In one embodiment, the controller 27 may increase the amount of light in the area where the display processing is performed as the surrounding brightness becomes brighter, that is, as the value detected by the illuminance sensor 24 increases. At this time, the controller 27 may increase the light quantity of the first display area emitting parallel light before increasing the light quantity of the second display area emitting the diffusion light. As a result, parallel light is more likely to be incident on the user's pupil than diffused light, so an image with the brightness desired by the user is displayed by an increase in the light amount smaller than in the case of increasing the light amount in the first region 111a. be able to. Further, in one embodiment, the controller 27 may increase the light amount of the entire area in which the display processing is performed as the surrounding brightness becomes brighter.

  In one embodiment, the controller 27 may increase the area in which display processing is performed as the surrounding brightness becomes brighter, that is, as the value detected by the illuminance sensor 24 increases. At this time, the controller 27 may increase the area where the first display area emitting parallel light performs the display process before the second display area emitting the diffused light increases the area performing the display process. As a result, since the ratio of parallel light incident on the user's pupil is larger than that of diffused light, the first region 111a increases the number of regions to execute display processing, thereby increasing the number of regions to execute display processing. Can display an image with a desired brightness. In one embodiment, the controller 27 may increase the area in which the display processing is performed in the entire area including the first area 111a and the second area 112a as the surrounding brightness is brighter. In one embodiment, the controller 27 increases the second display area for emitting diffused light to execute the display process before the first display area for emitting parallel light increases the area to execute the display process. May be

  FIG. 13 is a flowchart for explaining the flow of processing by the electronic device 1 according to an embodiment.

  The controller 27 determines whether the current time is within a predetermined time (step S101). When the controller 27 determines that the current time is within the predetermined time (step S101 / Yes), the controller 27 executes the first display mode (step S102). When the controller 27 determines that the current time is not within the predetermined time (step S101 / No), it determines whether the detection result of the illuminance sensor 24 is equal to or more than the predetermined (step S103). When the controller 27 determines that the detection result of the illuminance sensor 24 is equal to or more than the predetermined value (step S103 / Yes), the controller 27 executes the first display mode (step S102). When the controller 27 determines that the detection result of the illuminance sensor 24 is less than the predetermined value (step S103 / No), the controller 27 executes the second display mode (step S104).

  In the flowchart of FIG. 13, steps S101 and S102 may be interchanged. Further, in the flowchart of FIG. 13, one or both of step S101 and step S102 may be omitted. When both step S101 and step S102 are omitted, the user of the electronic device 1 may set the first display mode or the second display mode by operating the electronic device 1 by itself.

  Further, even if both steps S101 and S102 are not omitted, the user of the electronic device 1 may be able to set the first display mode or the second display mode by operating the electronic device 1 by itself. According to this, for example, from the second display mode by the intention of the user, when the user can focus without displaying an image in the second display mode, such as when the user wears glasses for glasses or near vision The setting of the electronic device 1 can be changed to the first display mode. In addition, even if the surroundings of the user are bright, that is, even if the first display mode is being executed, if the user wears glasses for glasses or near-eye glasses, the user focuses more than when naked eyes It is easy to match. Therefore, the ratio of diffused light to parallel light in the first display mode set by the user operation may be larger than the ratio of diffused light to parallel light in the first display mode set regardless of the user operation. In this case, the electronic device 1 may be able to switch between the first display mode not based on the user operation and the first display mode set by the user operation. According to this, in the bright place, when the user wears reading glasses or glasses for near vision, it is possible to increase the ratio of the diffused light in the first display mode by the user operation.

  According to the above embodiment, when the light emitted from the display 11 is collimated by the microlens array 12, the amount of light entering the eye is larger than when the diffused light from the display 11 is directly incident on the pupil of the user The image looks bright to the user. Also, for example, even if the user does not want more images, according to one embodiment, the display unit 10 uses the microlens array 12 with less power than a display unit that does not have the microlens array 12. It is possible to display an image of the same brightness as a display unit that is not provided.
