Further, when reversing the lens diameter is increased attempts to increase the number of parallaxes, the stereoscopic display resolution is reduced. In other words, an increase in the number of parallaxes is in a trade-off is a barometer of the resolution increases and three-dimensionality of a stereoscopic display.
[0008] As a method for increasing the number of parallaxes, for example, with respect to the light emitting pixel a microlens array is relative motion, there is a method to refract light in a plurality of directions (for example, see Patent Document 4). Further, there is a method of controlling the position of the droplets of liquid lens (e.g., see Patent Document 5)

In so that to be described later, the lower electrode 61- 1 to the lower electrode 61 - 4 are both an electrode ing to the upper electrode 65 pairs, as necessary, a predetermined voltage between the upper electrode 65 It applied. In the following, when there is no need to be distinguished from the lower electrode 61 - 1 to the lower electrode 61 - 4 it will be simply referred to as the lower electrode 61.
[0063] Between the lower electrode 61- 1 to the lower electrode 61 - 4 and the upper electrode 65, the insulator 62 from the bottom, the layers of the nonpolar liquid 63 and the polar liquid 64, is formed.
[0064] insulator 62 is, for example, a polymer of fluorine-based, PVdF, force hydrophobic PTFE or the like is used, and the dielectric constant is large material is desirable. At that time, although the film thickness is better thinner is desired in order to increase the dielectric constant, thicker Considering surface force of the insulating strength is desirable tool optimum value is determined in consideration of both. For example, if the Teflon (DuPont) 0.5醒膜thickness, the lower electrode 61 is an ITO electrode, the insulator 62 Teflon 0.5 (s Awakening), nonpolar liquid 63 is dodecane 25um, polar liquid 64 is water 100um, if the upper electrode 65 is an ITO electrode, mosquitoes such exhibit breakdown to 40V in the experiment ゝ ivy. Incidentally, the insulator 62, such as using the transparency materials, setback as possible the emitted light passing through the liquid lens portion 56 V, being configured such that desired.
[0065] the nonpolar liquid 64, decane, dodecane, to hexadecane, or charcoal hydrocarbon-based material such as Undekan, high refractive index silicone oil or a 1,1 Jifue - Ruechiren is used. By wettability change between insulator 62 and electrode liquid 64 by applying a voltage between the lower electrode 61 and the upper electrode 65, if Re der those results shape of the liquid varies as limited in particular I,.
[0066] in a polar liquid 64, for example, water, potassium Shioi匕, or an aqueous solution obtained by dissolving an electrolyte such as Shioi匕 sodium small methyl alcohol having a molecular weight, or alcohols such as ethyl alcohol is used. However, the polar liquid 64, wettability is changed between the nonpolar liquid 63 by applying a voltage between the lower electrode 61 and the upper electrode 65, is not limited in particular if Re der what changes the shape of the liquid . However, the polar liquid 64 and the nonpolar liquid 63 is not mixed with each other, unlike the refractive index is increased with each other, and, (based on the viewpoint of the shape change rate,) it is preferable that both the intended low viscosity.
[0067] The upper electrode 65 is an electrode corresponding to the lower electrode 61 is formed on the lower surface of the transparent plate 60-1 in a similar manner using the same material as the lower electrode 61. That is, the upper electrode 65 is a transparent electrode formed of a thin film of indium oxide (ITO) or Sani匕 zinc (ZnO), ideally, be configured so as not to interfere with the emitted light passing through the liquid product lens unit 56 that. However, the upper electrode 65 is different from the lower electrode 61 consisting of a plurality of electrodes, a single electrode formed on the entire liquid lens portion 56 (solid electrode). That is, the upper electrode 65, any of the lower electrode 61 - 1 to the lower electrodes 61 - 4 are opposed to the passage direction of the light.
[0068] Light passing through the liquid lens portion 56, the transparent plate 60-2, (lower electrode 61) insulator 62, (nonpolar liquid 63,) the polar liquid 64, the upper electrode 65, and the transparent plate 60- 1 passing through the layers. The layer of the lower electrode 61 is not formed on the entire passage area of ​​the light, a gap is generated as shown in Figure 5. Therefore, depending on the passing position, the light is also Ikoto such passes through this layer. The layer of the nonpolar liquid 63 to deform by applying a voltage between the electrodes, may not light passes through this layer by passing position or the like. [0069] ribs 66- 1 and the rib 66-2 is a partition separated Ru liquid lens portion 56 to each other are arranged in an array. More specifically, the ribs 66- 1 and the rib 66-2 is separated layers of the nonpolar liquid 63 of the liquid lens portion 56. In practice, the ribs 66 - 1 and the rib 66-2 is one of the partition member of the network th shape (lattice shape). In other words, each partitioned by the ribs 66 - 1 and the rib 66- 2 are configured as one liquid lens portion 56. If there is no need to distinguish the ribs 66- 1 and ribs 66- 2 to each other in the following, it referred to as the rib 66.
[0070] ribs 66, for example as in 榭脂 like epoxy or acrylic, not dissolved in the polar liquid 64 and the nonpolar liquid 63, and, in that neither reaction desirable instrument typically polymer of 榭 fat is used, for example, an epoxy or acrylic resin. Incidentally, the ribs 66, Do passes light, being configuration desired by an opaque member.
[0071] The liquid lens portion 56, as described later, by suitably applying a voltage between the lower electrode 61 and the upper electrode 65, and controls the shape and position of the polar liquid 64, whereby the non-polar to control the shape and position of the liquid 63, due to its nonpolar interface of the liquid 63 and the polar liquid 64, and controls the optical path of passing over the light. That is, the ribs 66, by separating the nonpolar liquid 63, it is possible to separate the structure of each liquid product lens unit 56. Therefore, the liquid lens portion 56 is actually force are arranged in an array (delimited by the ribs 66), as shown in FIG. 6, a shareable member is shared with other liquid lens portion 56 ing. For example, in the example of FIG. 6, the transparent plate 6 0-1, the transparent plate 60-2, the insulating layer 62, the polar liquid 64 and the upper electrode 65, is shared in all of the liquid lens portion 56, the rib 66 (e.g., ribs 66- 2 and ribs 66- 3), respectively, are shared by the liquid lens portion 56 adjacent.
[0072] That is, in the example shown in FIG. 6, the nonpolar liquid 63 for controlling the optical path, the lower electrode 61 (lower electrode 61- 1 1 to the lower electrode 61 - 1 to control the position of the nonpolar liquid 63 4, the lower electrode 61- 2 1 to the lower electrode 61 - 2 4, and, only the lower electrode 61 - 3 1 to the lower portion electrode 61- 3- 4), the liquid lens portion 56 (or even smaller units ) and provided we are in each, otherwise are shared.
[0073] Returning to FIG. 5, in the liquid lens portion 56 having such a configuration, a voltage is applied is controlled by the control unit 51 between the lower electrode 61 and the upper electrode 6 5. As shown in FIG. 5, the control unit 51 includes a power supply 71 and the connection selecting portion 72. Power supply 71 is connected between the connection selecting portion 72 and the upper electrode 65, a voltage applied between the upper electrode 65 and lower electrode 61 (by Ri selected lower electrode connection selecting portion 72) supplies. Connection selection unit 72 is a switching unit for selecting from among the lower electrodes 61 - 1 to the lower electrode 61-4, the electrode to be connected to a power source 71 (upper electrode 65 via a). In other words, the connection selecting portion 72 controls the state of application of the respective voltages of the lower electrode 61 - 1 to the lower electrode 61- 4. In FIG. 5, the control unit 51, only portions related to the electrical connection of the upper electrode 65 and lower electrode 61 are shown. In practice, the control unit 51, the configuration other than that shown in FIG. 5, for example, also have configurations such determination unit 53, the shape control unit 54, and a position control unit 55 shown in FIG. That is, the selection control unit 72 of FIG. 5, for example, determine tough 53 shown in FIG. 4, under the control of such shape control unit 54, and the position control section 55, the lower electrode 61 to connect to a power source 71 select.
[0074] Thus, the liquid lens portion 56, a predetermined voltage between the upper electrode 65 and lower electrode 61
By application of (the power supply voltage of 71), by changing the shape of the nonpolar liquid 63, the selection of the lower electrode 61 for applying a voltage, varying the position of the nonpolar liquid 63, controls the emission Direction of transmitted light to.
[0075] Incidentally, FIG. 5, both the voltage of the lower electrode 61 - 1 to the lower electrode 61- 4 shows a state that has not been applied (OFF). That is, in this case, the connection selecting portion 72, both of the lower electrodes 61 - 1 to the lower electrode 61 - 4 not to be connected to the power supply 71, is open (disconnected).
[0076] Thus, in a state where a voltage between the electrodes is not applied, the interface between the two layers due to the nonpolar liquid 54 and the polar liquid 53, the influence on the optical path of the light emitted from the parallax image displaying portion 11 as not adversely, it is important to the horizontal in the figure 5, for example, the shape of the insulator 62 and the ribs 66, due to the wettability of the atmosphere and the like for the polar liquid 64 and the nonpolar liquid 63. Thus, each part constituting the liquid lens portion 56 (in particular, the insulator 62, the polar liquid 64, the nonpolar liquid 63, and the rib 66) made of, size, shape, etc., a ヽ a voltage is applied between the electrodes , in the state, is also determined in consideration of the interface between the two layers due to the nonpolar liquid 63 and the polar liquid 64 to be horizontal. [0077] However, not necessarily, in some cases the entire interface between the two layers due to the nonpolar liquid 63 and the polar liquid 64 is water earnestly required are summer Nag sometimes need only partially leveled.
For example, if the portion that emits light mainly passes from the parallax image displaying portion 11 such as to concentrate on part of the interface, only that portion need only be leveled. In more additional remark, if considered equivalent to the case where substantially the entire of the two layers according to the nonpolar liquid 63 and the polar liquid 64 interface is horizontal (the interface does not affect the optical path), the interface whatever the state (shape), it is.
[0078] Next, an example of a reference to a lens movement control to FIGS. 7-10.
[0079] FIG. 7 is a nonpolar liquid 63, which shows an example of when moving in the right side in the figure in the liquid lens portion 56. 7, the connection selecting portion 72, the lower electrode 61- 1, the lower electrode 61- 2, have been and the lower electrode 61 4 Power 71 〖this connection, these electrodes becomes "ON" state ! /, Ru. In other words, the lower electrode 61- 1, between the lower electrode 61 - 2 and the lower electrode 61 - 4 and the upper electrode 65, the voltage of the power source 71 is applied. In contrast, the connection selecting portion 72 is open not to connect the lower portion electrode 61- 3 to the power supply 71. In other words, the lower electrode 61- 3 is "OFF" state, the voltage of the power supply 71 is not applied between the lower electrode 61 - 3 and the upper electrode 65.
[0080] The lower electrode 61 - 1 Thus, the lower electrode 61- 2, and the lower electrode 61 - 4, the voltage of the power source 71 is applied between the upper electrode 65, lower electrode 61- 1, lower electrodes 61- 2, and polarized charges to the electric field direction is generated in the insulator 62 of the lower electrode 61 - 4 near surface charge in the vicinity of the insulator 62 is accumulated (charged bilayer state). Polar liquid 64 to have one lifting polarities, the lower electrode 61- 1 by Coulomb force, and WHETHER the lower electrode 61- 2 and the lower electrodes 61-4 near the insulator 62. In other words, the lower electrode 61- 1, the lower electrode 61- 2, and the polar liquid 64 is approaching the insulator near the lower electrode 61 - 4 neighborhood. Nonpolar liquid 63 is a nonpolar contrast but therefore such force does not occur. Therefore, the lower electrode 61- 1, the lower electrode 61- 2 and the lower electrode 61- 4 near the insulator near neighbor of the nonpolar liquid 63, is pushed aside by the polar liquid 64, the voltage between the upper electrode 65 been applied, Do, gathered insulator vicinity 62 of the lower electrode 61 - 3 vicinity, becomes Ekishizukujo, the interface between the polar liquid 64 is lenticular.
[0081] In this case, the interface between the nonpolar liquid 63 and the polar liquid 64, the difference in refractive index of the second liquid, the shape of the interface, the light emitted from the parallax image displaying portion 11 (passing light of the liquid lens portion 56 ) refract light paths. Thus the liquid lens portion 56 actually generates the parallax of parallax images as described below.
[0082] In addition, curvature of the interface is based on the refractive index of the nonpolar liquid 63 and the polar liquid 64, the refractive index of the passing light is previously adjusted so as to optimize. In other words, the material of each part constituting the liquid lens portion 56, the size, the voltage applied between the electrodes Nag only shape also, so that the refractive index of the passing light becomes optimal, advance or appropriate, are determined.
[0083] FIG. 8 shows an example of optical paths in the state of FIG. 8, the liquid lens unit 5 6, the light emitted from the light-emitting pixel 81 and the light-emitting pixels 82 of the parallax image displaying portion 11 (visual information) is arranged to be incident. At this time, the outgoing light (visual information) of the light emitting pixel 81 and the light emitting pixel 82 of the parallax image display unit 11 is a light for stereoscopic display (an image including parallax images). The light emitting pixel 81 and the light-emitting pixels 82, in consideration of the lens characteristics of the nonpolar liquid 63, the focal distance (distance indicated by the double arrow 91), is provided spaced a liquid lens portion 56.
[0084] the light emitted from the light-emitting pixel 81 and the light-emitting pixels 82 (i.e., passing light of the liquid lens portion 56) is refracted by the shape of the interface between the nonpolar liquid 63 and the polar liquid 64 emitted from the liquid lens portion 56 It is. For example, in the case of FIG. 8, the light 101A and light 102A is emitted from the light-emitting pixels 81, respectively, it is refracted at the interface between the nonpolar liquid 63 and the polar liquid 64, the liquid lens as a light 101B and a light 102B It is emitted from part 56. Similarly, for example, light 103A and a light 104A is emitted from the light-emitting pixels 82, respectively, it is refracted at the interface between the nonpolar liquid 63 and the polar liquid 64, emitted from the liquid lens portion 56 as light 103B and a light 104B It is. Therefore, by arranging like this, the liquid lens portion 56, the Ideally, it is possible to emit transmitted light as a light close to parallel light or collimated light.
[0085] Figure 9, as opposed to the case shown in FIG. 7 shows an example of a case where the nonpolar liquid 63, is moved to the left in the figure side of the liquid lens portion 56. 9, the connection selecting portion 72, the lower electrode 61 - 1, connects the lower electrode 61 - 3, and the lower electrode 61 - 4 to the power source 71, these electrodes are "ON" state. In contrast, the connection selecting portion 72 is opened not to connect the lower electrode 61-2 to the power source 71, Ru (ROFFj state).
[0086] As in FIG. 7, a voltage is applied, Coulomb force that occur with respect to the polar liquid 64. Therefore, the lower electrode 61- 1, the lower electrode 61- 3 and the lower electrode 61-4 near the absolute Entai nonpolar liquid 63 in the vicinity, is pushed aside by the polar liquid 64, a voltage applied between the upper electrode 65 It is! , I! / Collects in the insulator near 62 of the lower electrode 61 - 2 vicinity Ekishizukujo next, the interface between the polar liquid 64 a lens shape.
[0087] Accordingly, as shown in FIG. 10, the light emitted from the light-emitting pixel 81 and the light-emitting pixel 82 (that is, transmitted light of the liquid lens portion 56), as in the case of FIG. 8, the nonpolar liquid 63 to be emitted from being refracted liquid lens portion 56 due to the shape of the interface between the polar liquid 64. For example, in the case of FIG. 10, the light 111A and a light 112A is emitted from the light-emitting pixels 81, respectively, it is refracted Te Contact! ヽ the interface between the nonpolar liquid 63 and the polar liquid 64, and optical 111B and light 112B It is emitted from the liquid lens portion 56 Te. Similarly, for example, light emitted der Ru light 113A and a light 114A from the light emitting pixel 82, respectively, interface with your V between the nonpolar liquid 63 and the polar liquid 64, is refracted Te, liquid as light 113B and a light 114B It is emitted from the lens unit 56.
[0088] In the case where the 8 in FIG. 10, the position of the nonpolar liquid 63 are different from each other.従Tsu Te, the emission direction of light passing through the liquid lens portion 56 (and the progress direction of light 101B or light 104B in FIG. 8, each traveling direction of light 111B or light 114B in FIG. 10) are different from each other. That is, the position control unit 55 of the control unit 51 controls the connection selecting portion 72, as shown in FIG. 9 (FIG. 10) and FIG. 7 (8), a voltage is applied between the upper electrode 65 from 〖this by selecting the lower electrode 61, it is possible to control the position of the nonpolar liquid 63. That is, the position control section 55, a lower electrode 61 for applying a voltage between the upper portion electrode 65, for example, by switching in synchronization with an integral multiple of the synchronizing signal of the displayed parallax images, the nonpolar liquid 63 it can be varied in position. By doing so, the emission direction of the emitted light of the liquid lens portion 56 is changed. That is, the liquid lens portion 56 may be one of light emitted from the light emitting pixels is more towards direction 〖this exit. In other words, the parallax generating portion 12 increases the number of parallaxes by each liquid lens portion 56 for antibody originating, it is possible to increase the visual difference number you! ヽ Te displayed parallax images to the parallax image displaying portion 11. [0089] In FIG. 7 and FIG. 9, the connection selecting portion 72 selects the lower electrode 61 to "ON" state, but this selection, shape control unit 54 and the position control unit 55 of the control unit 51 it is due to both the control result.
[0090] For example, the shape control unit 54 and controls the connection selecting portion 72 so as to the shape of the nonpolar liquid 53 Lenticular (state as parallax occurs), the connection selecting portion 72, an initial state as shown in FIG. 7 Te, a voltage is applied to the lower electrode 61, further, when the position control unit 55 controls the connection selecting portion 72 so as to vary the position of the nonpolar liquid 53, the connection selecting portion 72 switches the lower electrode 61 to "oN" state, a state shown in FIG. Thereafter, connection selection unit 72 based on control of the position control unit 55, switches repeated connection of the lower electrode 61, so as to repeat the state shown in state and 9 shown in Figure 7, the non-polar liquid varying the position of the body 53. Then, to exit the position variation controls the connection selecting portion 72 so that the position control unit 55 terminates the switching of the connection, if ending the parallax generating the shape control unit 54 is a connection selecting portion 72 controlled, thereby all the lower electrodes 61 to the "OFF" state.
[0091] By doing so, the parallax generating portion 12 can also perform shape control not only the position control of the nonpolar liquid 63. That is, in this case, the parallax generating portion 12, the presence or absence of parallax generated Nag in only the number of parallaxes increase or decrease also becomes controllable.
[0092] In the initial state pattern of the voltage applied to the lower electrode 61 described above, Yogu example Even otherwise the Nag only pattern of FIG. 7, Choi a pattern shown in FIG.
[0093] By switching the position of the nonpolar liquid 63 as described above, the parallax generating portion 12, it is possible to generate a parallax of parallax images displayed on the parallax image displaying portion 11, simply apolar liquid 63 even if the position is varied, actually, as shown in FIG. 11, there is a possibility that the emission direction overlaps.
[0094] FIG. 11 is an emission direction is controlled, Do is a schematic diagram showing an example of a state of parallax generated when.
[0095] In FIG. 11, the light emitting pixel 121 to the light emitting pixel 123 shows an example of a luminescent image elements of the parallax image displaying portion 11, the liquid lens 124 - 1 and the liquid lens 124 - 2, the parallax generating portion 12 shows an example of a state of positional change of the nonpolar liquid 63 of the liquid lens portion 56, light 1 31 to beam 136, liquid lens 124 - is 1 and emitted from the liquid lens 124 - 2, the light emitting pixel 121 to light emitting It shows an example of the output light of the pixel 123, Ru.
[0096] That is, light rays 131 emitted from the light emitting pixel 121, the light passing through the liquid lens 124 - 1 (nonpolar liquid 63 is controlled to move to the position represented by the liquid lens 12 4 1) It is shown. Similarly, ray 132 is emitted from the light emitting pixel 122 shows the light passing through the liquid lens 124-1, light rays 133 emitted from the light emitting pixel 123, a light spent through the liquid lens 124-1 shows. In contrast, light rays 134 emitted from the light emitting pixel 121 and passes through the liquid lenses 124 - 2 (non-polar liquid 63 which is controlled to move to the position represented by the liquid lens 124 - 2) Light the shows. Similarly, ray 135 is emitted from the light emitting pixel 122 shows the light passing through the liquid lens 124-2, light rays 136, shines out from the light-emitting pixel 123, the light passing through the liquid lens 124-2 shows.
[0097] As the liquid lens 124 - 1 and the liquid lens 124 - 2, be varied the position of the nonpolar liquid 63 of the liquid lens portion 56, as shown in FIG. 11, the beam direction the position of the emitted light in some cases overlap with the previous fluctuations. In other words, as the force entire outgoing light that is Ru can switch the central axis of each outgoing light overlaps with the previous change light. When directed force the user in this way overlap the plurality of the emission light to see the parallax images, it appears to overlap a plurality of images, or looked image should be still images to moving images, or visible image flickers, there is a possibility that the color and shape or looked strange Watte. That is, if such, the position of the user viewing the parallax images, it may not be possible to show the original intended image correctly.
[0098] Therefore, as shown in FIGS. 12 and 13, in a predetermined direction by moving the lens to shift the light beam direction, there is no light in the initial state (state prior to shift the beam direction) so as to. Hereinafter, an example of how the emission direction control will be described with reference to FIGS. 12 to 14.
[0099] FIG. 12 is a schematic diagram showing an example of a direction of emission of the case where the position of the nonpolar liquid 63 of the liquid lens portion 56 is in the other hand (the position can be represented by the liquid lens 124 - 1). For Figure 1 2, the display unit 22 of the parallax image displaying portion 11 is made the structure as shown in each of FIGS. 2 and 3, the emitted light is separated by a predetermined interval for each emission pixel It is emitted Te. Light source 140, which illustrates such a state, the three light emitting pixels (light emitting pixel 141 to the light emitting pixel 143) are separated fractionated by spacer 144 to spacer 147 of a predetermined size. For example, the display unit 22 of the parallax image displaying portion 11, when having a pinhole filter 35 as shown in B of FIG. 3, the light emitting pixel 141 to the light emitting pixel 143, each pin hole (opening of the pin hole filter 35 represents the light that is emitted from the part)! /, Ru.
In [0100] Figure 12, the nonpolar liquid 63 of the liquid lens portion 56 is controlled to a position where it is and this represented by the liquid lens 124 - 1. Light 151 is emitted from the light emitting pixel 141 indicates the traveling direction of the light passing through the liquid lens 124-1. Similarly, the light 152 is emitted Ri good luminescent pixels 142 indicates the traveling direction of the light passing through the liquid lens 124-1, the light 153 is emitted from the light emission pixels 143, the liquid lens 124-1 indicates the traveling direction of light that has passed through
[0101] As shown in FIG. 12, since it is separated by the light emitting pixel 141 to the light emitting pixel 143 Gasupesa 144 to space over support 147, the light 151 to light 153 are separated from each other, a gap (optical 151 to light 153 the direction) occurs not reach.
[0102] FIG. 13 is a schematic diagram showing an example of a direction of emission of the case where the position of the nonpolar liquid 63 of the liquid lens portion 56 is in the other (the position can be represented by the liquid lens 124 - 2). Light 1 54 is emitted from the light emitting pixel 141 indicates the traveling direction of the light passing through the liquid lens 124-2. Similarly, the light 155 is emitted from the light emitting pixel 142, the liquid lens 124-2 shows the traveling direction of the light passed through the light 156 is emitted from the light emitting pixel 143, the liquid lens 124 - 2 It shows the traveling direction of the light that has passed through! /, Ru.
[0103] As in the case of FIG. 12 in the case of FIG. 13, the light 154 to light 156 are separated from each other, the gap
(Direction Light 154 to which the light 156 does not reach) occurs.
[0104] In this case, the size of the spacer to the same size as the light emitting pixel. That is, the ratio of light emission pixels at the exit surface of the light source 140 to 1Z2. For example, if having a pinhole filter 35 as the display unit 22 is shown in B of FIG. 3, (for the entire parallax image display surface portions percentage of light is emitted) open mouth rate of the pinhole 36 and 1Z2 the to. That is, for example, when the light emitting element portion of each light-emitting pixels of the display portion 22 are arranged without gaps array, the area of ​​the pinhole 36 corresponding to each light-emitting pixel, and half of the light emitting element portions.
[0105] By doing so, the light source 140, the ratio of the surface product of the liquid lens 124 - 1 viewed from the light emitting portion is halved. In other words, the proportion of light 151 to light 153 (light 154 to light 156) for the entire range of emission directions of light of the liquid lens 124-1 to the entire light source 140 (liquid lenses 124 - 2) is halved. In other words, the range and magnitude of the range of the clearance of light 151 to light 153 are equal. At the same time, it equal the size of each range and the range of the gap of the light 154 to light 156.
[0106] By combining such two states best shown in FIGS. 12 and 13, ie, the liquid lens 124 - 1 and the difference in position of the liquid lens 124 - 2 (i.e., the nonpolar liquid 6 3 by optimally by adjusting the position variation amount), as shown in FIG. 14, the light after the lens moves can be made to fit without clearance between the rays of the initial state. That is, in the case of this FIG. 14, each light 151 to light 156 are both not overlap with other light, also, even if the gap between the other light, I,.
[0107] In this way, the user to view a parallax image, in any position forces, without uncomfortable, such as flickering or overlap, it is possible to view the image corresponding to the position correctly.
[0108] That is, the parallax image display device 1, by varying the lens position, the number of parallaxes of the lens per without reducing the resolution of the image can be increased, further, the aperture ratio of the light source, the lens position by adjusting the amount of variation, it is possible to suppress a decrease in image quality.
[0109] In the above, there has been described a case where the display unit 22 is provided with a pin-hole filter 35, the display unit 22, also filed in other configurations, such as described above with reference to FIGS. 2 and 3 Of course, good.
[0110] Further, in the above, (the number of positions which the position control unit 55 controls) number of positions of the force the nonpolar liquid 63 described to vary the nonpolar liquid 63 between the two positions is , it may be three or more positions as described below. However, without overlapping the traveling direction of the light from each other emitted from the liquid lens portion 56 as shown in FIG. 14, and, in order to prevent a gap, the position of the position control unit 55 controls the number of N (N is an integer and,, N≥2) of the result, Ru need to the aperture ratio of the light source 140 shown in FIGS. 12 to 14 to 1 Zn. [0111] Next, a description will be given of the amount of movement of the nonpolar liquid 63 for performing directional control of the light as shown in FIG. 14.
[0112] the lens from the light source, since the put away by the focal length of the lens, (although strictly different) the rays emitted from each lens'll assumed to be parallel light, emitted from the lens and, the slope of the edge of the bundle of light corresponding to each pixel is substantially the same as the slope of the straight line passing through the center of the lens from both ends of each pixel.
[0113] Hereinafter, to indicate the ends of the light 151 to light 156 shown in FIG. 14, the gradient of each straight line. However, the upper end of each beam and H, and the lower end. Further, (each, longitudinal length in view of the light emitting pixel 141 to the light emitting pixel 143 in FIG. 14) as the A, the liquid lens 124 - 1 and the liquid lens 124 - 2 (non-polar Sa I's of the respective light emitting pixels a liquid 63) the gap of the light source and X, the movement amount of the liquid lens 124 - 1 and the liquid lens 124 - 2 (nonpolar liquid 63) (the difference position of the liquid lens 124 - 1 and the liquid lens 124 - 2) Y far.

[0115] Here, for example, interest positional relationship between the light 156 and light 152. 15, the light 1
56 and shows the positional relationship between the light 152. 15, dotted lines 156H and point line 156L, respectively, shows the upper end of the light 156 and the lower end, the solid line 152H and a solid line 15
2L respectively show the upper end of the light 152 and the lower end. [0116] As shown in FIG. 15, overlap of the two regions of the light 156 and light 152 is determined by the relationship between the dotted 156L and the solid line 152H. That is, the dotted line 156L and the solid line 152H, respectively, also in that it shows a lower end and an upper end of the portion where the light 1 56 and the light 152 overlap. Thus, as much as possible, in order to light 156 and light 152 do not overlap, set to be as much as possible parallel to each other and dotted 156L and the solid line 152H (to be closer) that is required.
[0117] emitting pixel size A is a constant, the lens and the distance X between the light-emitting pixel is also a constant, is a lens movement amount y What determines the slope of the dashed line 156L and the solid line 152H. In other words, it overlaps with Rigo, degree of, will be determined by the amount of lens movement Y.
[0118] The relationship between the moving direction of the lens movement amount Y and the light 156 and light 152 shown in FIG. 16. A in FIG. 16, the value of the lens movement amount Y indicates the state of the light emitting pixel size A larger (Y> A) of the case, the light 156 Contact and light 152. In this case, would be the area of ​​the region and a light 152 of the light 156 away from each other, light is delivered force no portion is generated. Therefore, in this case, the position Looking at parallax image is an image to view the user, each pixel location has become uneven, there is a fear that unevenness such as unwanted dark portion occurs occurs. That is, in this case, the quality of the image seen by the user is reduced.
[0119] B of FIG. 16 shows the contrary to the case of A in FIG. 16, the value of the lens movement amount Y is emitting pixel size A is smaller than (Y rather A) in the case, a state of light 156 and light 152 ing. In this case, the area of ​​the region and a light 152 of the light 156 is mutually largely overlap Gotsu. The dotted line 1 56L and solid 152H described above can Do parallel to each other ヽ, therefore, further away from the parallax generating portion 12, the area of ​​which overlap Gotsu region increases. That is, in this case, the position to view a parallax image, resulting unevenness in an image that the user sees, flickering, deformation, undesired phenomena such as discoloration may occur. In other words, in this case also decreases the image quality of the image seen by the user wait.
C of [0120] FIG. 16, the value of the lens movement amount Y indicates the state of the light emitting pixel size equal to A (Y = A) of the case, the light 156 and light 152. In this case, as much as possible becomes parallel to each other and dotted 156L and the solid line 152H, the size of the region where the light 156 and light 152 overlap is minimized. That is, by the light emitting pixel size A lens movement amount Y, deterioration of image quality due to light overlapping the like can be minimized. The size of the overlapping portion in this case is an amount obtained by subtracting the amount of movement y of the lens diameter, usually, for a degree greater than about 300 m, the user can also look at the images to confirm the overlap thereof it is almost impossible.
[0121] That is, the parallax image display device 1 of FIG. 1 according to the present invention, it is possible to generate more parallaxes without reducing the resolution and image quality.
[0122] Incidentally, such a liquid lens portion 56 can be manufactured as follows, for example. Lower portion electrode 61 is formed, for example, an electrode with a film in a predetermined manner the ITO film on a substrate made of glass. Also the upper electrode 65 is formed in the same manner. The insulator 62 was formed on the substrate having the lower electrode 61 form a film by a spin coating method or a dip coating method, or the like. For example, in the film formation according to a Teflon (registered trademark) (DuPont) spin coating method in a 3% solution of 1601s, 150 0rpm, in conditions of 60 sec, the film thickness is about 0.5um. The solution concentration of 1% to 6%, it is possible to control several microns from submicron scan Pinkoto speed 1500rpm to 5000 rpm.
[0123] In addition to forming a network of ribs 66 thereon. Rib pixel size at this time is determined by matching with the Display I pixel. For example, using a resist epoxy 榭脂 can be produced by a given photolithographic technique or the like. When using a fluoride compound-based as the insulator 62, the resist is thus repelled relationship mosquito Ra wettability, this problem can be avoided by devising the manufacturing process. For example, Teflon powder MicroChem S U-8 3050 resist on, when applying using a blade, but would les resist is repelled when subjected to a normal process after coating, cold soft beta step (50 ° C) long or in, or can be painted a resist onto Teflon it or to room temperature air drying. Although blade height setting can control the height of the rib 66 up to several um to hundreds of um, lower from the second drop of the operating speed viewpoint, what is desired.
[0124] Thereafter, spraying the gap-shaped Naruzai as inter-electrode distance between the lower electrode 61 and upper electrode 65 becomes a predetermined value to the lower electrode periphery. For example, those mixed with silica spheres Ya seal adhesive type and the like to the adhesive.
[0125] Thereafter, the nonpolar liquid 63 in the rib pixel, is injected in the order of the polar liquid 64. At this time, the relationship mosquito ゝ Luo polar liquid 64 of the wettability, irrespective gravity of the nonpolar liquid 63, the nonpolar liquid 63 is lower, the polar liquid 64 is shaped overlying stable. At this time, it is possible to change the second shape of the liquid in the steady state with a hydrophilic variation of the rib 66 by elevation ultraviolet irradiation. For example, after injection rib size 0.6 mm X 0.6 mm using gunpowder MicroChem SU-8, and have contact with the height 50um, the liquid 1 when used water, the liquid 2 in dodecane, dodecane on one side in the rib, a method of sealing death with an epoxy adhesive after pouring a large amount of water from the top, by way of UV irradiation morphism time 10 minutes diameter of dodecane to become 400 um, the intended 30 minutes became 250 um. This is attributed to the difference in hydrophilicity strength of the rib 66 due to a difference in the irradiation time.
[0126] Then, an upper substrate, bonding the lower substrate gap forming material is sprayed, for sealing the panels periphery of the Awa bonding a sealing 榭脂. Sealing 榭脂, for example, ionomer, and an adhesive polyethylene. The aforesaid process liquid lens structure can be manufactured beam direction control device deployed in a two-dimensional shape.
[0127] Note that Te is higher Nio ヽ has been described control position of the nonpolar liquid 63 (the location of moving the nonpolar liquid 63) as two points, control the position of the nonpolar liquid 63 was at least three also of course good.
[0128] With reference to FIGS. 17 to 21, control the position of the nonpolar liquid 63 describes the case of three.
[0129] Figure 17, in this case, is a schematic diagram showing a configuration example of the liquid lens portion 56, a view control position corresponds to Figure 5 in the case of two locations. In the case of FIG. 17, the configuration of the liquid lens portion 56 is basically the number of force lower electrode 61 is similar to that of FIG. 5 is different. For Figure 17, it has six lower electrode 61 disposed on a plane (the lower electrode 61 - 1 to the lower electrode 61 - 6).
These lower electrodes 61 - 1 to the lower electrode 61 - 6, both connected to the connection selecting portion 72, the connection between the power source 71 is switched by the connection selecting portion 72. That is, of the lower electrode 61 - 1 to the lower electrode 61 - 6, the lower electrode 61 which is selected in the connection selecting portion 72, a voltage is applied between the upper portion electrode 65. In FIG. 17, 61- 6 lower electrode 61- 1 to the lower electrode are both not connected to the power source 71 are all "OFF" state. Nonpolar liquid 63 at this time, for example, the interface between the polar liquid 64 is made horizontally (in the horizontal direction), Do affect the optical path of the transmitted light, as done is in!, Ru. [0130] Figure 18, in the example of the liquid lens portion 56 of FIG. 17 is a diagram showing an example of positioning the nonpolar liquid in the right side in the drawing. 18, the connection selecting portion 72, the lower electrode 61- 1 to the lower electrode 61 - 3, and, connected to the power supply 71 to select the lower electrode 61-6, and the "ON" state. Thus, the polar liquid 64 is lower electrodes 61- 1 to the lower electrode 61 - 3, the parallel beauty, so gather near the lower electrode 61-6, the nonpolar liquid 63, as a result, the lower electrode of the "OFF" state 61 4 and positioned in the lower electrode 61- 5 vicinity (in the figure in the liquid lens portion 65 on the right).
[0131] FIG. 19 is the liquid lens portion 56 of the example of FIG. 17 is a diagram showing an example of positioning the nonpolar liquid Zuchu center. 19, the connection selecting portion 72, the lower electrode 61- 1 and the lower electrode 61 - 2, and is connected to the power source 71 to select the lower electrode 61- 5 and the lower electrode 61 - 6, the "ON" state ing. Therefore, the lower electrode 61-1 and the lower electrode 61 - 2 polar liquid 64, and, since the whole current in the vicinity of the lower electrode 61-5 and the lower electrode 61-6, the nonpolar liquid 63, as a result, "OFF" located in the lower electrode 61 - 3 and the lower electrode 61- 4 near the state (middle in the figure in the liquid lens portion 65).
[0132] FIG. 20 is the liquid lens portion 56 of the example of FIG. 17 is a diagram showing an example of positioning the nonpolar liquid on the left side in the figure. In Figure 20, the connection selecting portion 72, the lower electrode 61- 1, and, connected to the power supply 71 to select the lower electrode 61-4 to the lower electrode 61-6, and the "ON" state. Therefore, the lower electrode 61- 1 polar liquid 64, and, since gather near the lower electrode 61- 4 to the lower electrode 61-6, the nonpolar liquid 63, as a result, the lower electrode of the "OFF" state 61- 2 and position the lower electrode 61- 3 near (left side in the figure in the liquid lens portion 65).
[0133] Thus, by the lens position is controlled at three positions, as shown in FIG. 21, each emitting light power from the light emitting pixel of Table radical 113 22, to proceed to three different directions It is controlled.
[0134] FIG. 21 is a diagram illustrating an example of how the emission direction control in this case.
[0135] In FIG. 21, because as shown by the liquid lens 181- 1 through the liquid lens 181- 3, the position of the nonpolar liquid 63 of the liquid product lens unit 56 is controlled at three positions, the light emitting pixel of the light source 140 three light emitted from each of the 141 to the light emitting pixel 143, the liquid lens 181 -1 through liquid lens 181- 3, as indicated by the light 191 to light 199, emitted in the nine directions that differ from each other.
[0136] In FIG. 21, the light 191 is emitted from the light emitting pixel 143, indicates the light passing through the liquid lens 181- 1, the light 192 is emitted from the light emitting pixel 143, passes through the liquid lens 181- 2 light are shown, light 193 is emitted from the light emitting pixel 143, indicates the light passing through the liquid lens 181- 3, light 194 is emitted from the light emitting pixel 142, indicates the light passing through the liquid lens 181-1, the light 195 is emitted from the light emitting pixel 142, indicates the light passing through the liquid lens 181- 2, light 196 is emitted from the light emitting pixel 142, indicates the light passing through the liquid lens 181- 3, the light 19 7, is emitted from the light emitting pixel 141, it indicates the light passing through the liquid lens 181- 1, the light 198 is emitted from the light emitting pixel 141, indicates the light passing through the liquid lens 181- 2, light 199, light emission pixels 141 is more emitted, the liquid lens 181 - shows the light passing through the 3, Ru.
[0137] At this time, the aperture ratio of the light source 140 since the control position of the nonpolar liquid 63 is three is set to 1Z3, distances between each position of the liquid lens 181- 1 through liquid lens 181- 3 ( the amount of movement of the liquid lens) is that is set equal to the size of each light-emitting pixel. The distance between the light source 140 and the liquid lens 181- 1 through the liquid lens 181- 3 is set to the focal length of the liquid lenses 181- 1 through the liquid lens 181- 3.
[0138] Hereinafter, to indicate the ends of the light 191 to light 199 shown in FIG. 21, the gradient of each straight line. However, the upper end of each beam and H, and the lower end. Also, the service I's of the respective light emitting pixels is A, the liquid lens 181- 1 through the liquid lens 181- 3 (nonpolar liquid 63) the gap of the light source and X, the liquid lens 181- 1 through liquid lens 181- 3 ( the amount of movement of the nonpolar liquid 63) (difference between the position of the liquid lens 181- 1 through liquid lens 181- 3) put a Y.
[0139] 191H: {(7/2) A + Y} / X
191L: {(5/2) A + Y} / X
192H: {(7/2) A} / X
192L: {(5/2) A} / X
193H: {(7/2) AY} / X
193L: {(5/2) AY} / X
194H: {(1/2) A + Y} / X 194L: {- (1/2) A + Y} / X
195H: {(1/2) A} / X
195L: {- (1/2) A} / X
196H: {(1/2) AY} / X
196L: {- (1/2) AY} / X
197H: {- (5/2) A + Y} / X
197L: {- (7/2) A + Y} / X
198H: {- (5/2) A} / X
198L: {- (7/2) A} / X
199H: {- (5/2) AY} / X
199L: {- (7/2) AY} / X
[0140] Therefore, as in the case control position is at two locations, the degree of overlap is dependent on the lens movement amount Y, the aperture ratio of the light source and 1Z3, by the lens movement amount Y = A, visual the difference generator 12, also in this case, it is possible to suppress to a minimum the image quality degradation due to overlapping of light.
[0141] Thus, a number to Rukoto the number N of the control position of the nonpolar liquid 63 in each of the liquid lens portion 56, the parallax image display device 1 can be further increased Caro the number of parallaxes. Even in this case, each part of the arrangement relation, the lens movement amount, since the aperture ratio and the like of the light source is properly set, the parallax image display device 1, without reducing the resolution and image quality, the number of parallaxes leave in be increased.
[0142] The number of the lower electrode 61, if a nonpolar liquid 63 in each of the liquid lens portion 56 as it can be moved to a predetermined control position, may be any number, mutually different dates Tei it may be. For example, in the example of FIG. 17 (if the control position of the three), may be the number of lower electrode 61 to 7 or more. Also, advance sufficiently positioned much lower electrodes 61 may be capable of changing the number of control positions according to the situation. Also, magnitude may be different from each other in each of the lower electrode 61, the control unit 51, may also be capable of applying a voltage of different voltage values ​​for each lower electrode simultaneously, one lower the voltage value of the voltage applied to the electrode 61, along the time axis, it may be to allow the child to continuously or discontinuously change.
[0143] In addition, the number of luminescent pixels corresponding to the liquid lens portion 56, i.e., the number of light emitting pixels is emitted light passing through each liquid lens portion 56, if the possible number generating a parallax of the parallax image, go even One, and then each other in each of the liquid lens portion 56 to each other!, to be different, even if,.
[0144] Next, with reference to the flowchart of FIG. 22, an example of the flow of by that image display processing to the display control unit 21 of the parallax image displaying portion 11.
[0145] For example, such a parallax image displaying device 1 of FIG. 1 is started, the image display processing is started, the display control unit 21 of the parallax image display unit 11 in step S1, the parallax image from the outside determining whether the image signal is supplied. When determining supplied with, the process proceeds to step S2, and controls the respective light emitting pixels of the display unit 22 based on the image signal, by emitting light as necessary, a parallax image corresponding to the supplied image signal on the display unit 22 a.
[0146] a display control unit 21 displays the parallax image, the process advances to step S3. Moreover, Te Contact ヽ the stearyl-up S 1, when the image signal of the parallax images from the outside is judged supplied by! ヽ a ヽ omits the processing of step S2, the flow proceeds to step S3.
In [0147] Step S3, the display control unit 22 to determine force not to end the image display processing. If it is determined not to end, the display control unit 22 returns the process to step S1, and repeats the subsequent processing. Further, in step S3, when the supply of the image signal is determined to end the image display process by, for example to stop for a while, the display control unit 22 ends the image Display processing.
[0148] By controlling as above, the display control unit 21 can display a parallax image on the display unit 22.
[0149] Note that, in step S1, the display control unit 21, the supplied image signal to determine mosquitoes ゝ whether the supplied "image signal of the parallax images", also includes the image signal of the normal two-dimensional image when the image signal other than the parallax image is supplied, may be omitted the process of step S2, simply determines whether the image signal is supplied, any image supplied image signal even the signals, may be the process proceeds to step S2. In other words, visual difference image display unit 11, may be allowed to be displayed only parallax images, even ordinary planar image other than the parallax images also can be displayed Yo,.
[0150] Next, with reference to the flowchart of FIG. 23, an example of the flow of parallax onset production control processing by the control unit 51 of the parallax generating portion 12.
[0151] For example, such a parallax image displaying device 1 of FIG. 1 is activated, the parallax generation controlling processing is initiated, the determination unit 53 of the control unit 51 of the parallax generating portion 12, in step S21, determines force not acquired external from the control information. If the control information is determined to have been supplied, the determination unit 53 advances the process to step S22, and based on the control information, determines a force not to generate a parallax.
[0152] When it is determined that generates a parallax of parallax images displayed on the parallax image displaying portion 11, determine tough 53 advances the processing to step S23. In step S23, as the shape control unit 54 controls the connection selecting portion 72, the interface between the polar liquid 64 of the nonpolar liquid 63 in a convex shape (lens shape), select the lower electrode 61 for applying a voltage is, a voltage is applied between the lower electrode 61 and the upper electrode 65 and the selected. When applying a voltage shape control unit 54 advances the process to step S24.
[0153] In step S24, the position control unit 55 controls the connection selecting portion 72, so that the position of the nonpolar liquid 63 at a predetermined period varies the length of the opening, between the upper electrode 65 to switch the lower electrode 61 for applying a voltage. Step processing position control section 55 to end of the S 24, the process advances to step S25.
[0154] In addition, our in step S21, Te, if it acquires from the control information externally, Do, was determined, the determination unit 53 advances the process to step S25. Further, in step S22, if it is determined not to generate parallax judging section 53 advances the processing to step S25.
[0155] In step S25, the determination unit 53 determines whether to end the parallax generation controlling processing, when it is determined not to end, the process returns to step S21, thereby repeated the subsequent processing. Further, in step S25, if it is determined to end the parallax generation controlling processing, determination unit 53 advances the processing to step S26. In step S26, the shape control unit 54 and the position control unit 55 controls the connection selecting portion 72, opens the connection of all the lower electrodes 61, the application of a voltage between the lower electrode 61 and upper electrode 65 finish. When ends the mark addition of voltage, shape control unit 54 and the position control section 55 exits the parallax generation controlling processing.
[0156] By controlling the generation of the parallax as described above, the control unit 51 of the parallax generating portion 12, braking Te based ヽ the control information, the parallax image displayed on the display unit 22 of the parallax image displaying portion 11 parallax can be generated for. At this time, as described above, since the emission direction of light is appropriately controlled while switching the position of the nonpolar liquid 63, the control unit 51 is able to generate more parallaxes without allowing reducing the resolution and quality as described above, it is possible to control each liquid lens portion 56 of the light path control part 52.
[0157] As described above, the parallax image display device 1 can display a parallax image while generating a parallax. Accordingly, the parallax image display device 1 is, for example, to display the ad A product to users located in the front right side of the parallax image display surface, etc. for displaying user B product advertisement located on the left front, different each user located in place, it is possible to display different images from each other.
[0158] In the above, has been described parallax image display unit 11 and the parallax generating portion 12 as part of the configuration of the parallax image display device 1 is not limited to this, the parallax image displaying portion 11 and the parallax generating portion 1 separate device 2 and respectively (e.g., the parallax image display device and a parallax generating device) may be be configured as a. In this case, for example, operate in cooperation with the parallax image display device and a parallax generating device, it performs the same operation as the parallax image displaying device 1 of FIG. 1 as a whole.
[0159] Also, in the above, the parallax image display device 1 has explains to generate a parallax in the horizontal direction, generating direction of parallax, Yogu be any direction, for example, in the vertical direction it may be a diagonal grain direction.
[0160] Further, using this disparity, it is possible to stereoscopically display an image by the IP method. Figure 24 is a diagram showing a configuration example of a wavefront control type display device according to the present invention.
In [0161] Figure 24, the wavefront control type display device 200, and displays a two-dimensional parallax images including a disparity information, by generating a parallax of parallax images and displays a two-dimensional image to look like solid a device for realizing the stereoscopic display (3D display). Wavefront control type Display device 200 includes a signal separation unit 211. Signal separator 211, Ru is supplied from the outside, it acquires the signal of the parallax image including both the parallax information and the image information, the signal, the signal containing image information (image signal) and the signal including the disparity information (disparity separating the information signal) and. Wavefront control type display device 200 further has a two-dimensional image display drive circuit 212 and the 2-dimensional image image display unit 213. Signal separating unit 211 supplies the image signal whose separation into two dimensional image display unit driving circuit 212.
[0162] 2-dimensional image display unit driving circuit 212 is a circuit configuration for driving the two-dimensional image display unit 213, when the clock signal and necessary based the synchronizing signal luminance signal, the equation difference signal or the like Te, and it supplies the image signal to the two-dimensional image display unit 213 causes driving the two-dimensional image display section 213. 2-dimensional image display section 213 that has a plurality of luminescent pixels 214 to expand into a planar shape. Emitting pixel 214 has, for example, also comprising semiconductor light emitting device power. The two-dimensional image display unit 213, nag only luminescent pixels 214 group other displays, for example, a liquid crystal display device, an organic electroluminescent display device, an electroluminescent display device, plasma display panel, elect port chromic display device, a display device using a fluorescent display tube, a display device using a cathode ray tube, or may be a projector or the like. Is not particularly limited as long as the wavefront controllable display device by the wavefront control section 216 to be described later.
[0163 emitting pixel 214 is constituted by a combination of elements capable of emitting light emitting device or a full-color of the individual single color.
[0164] Further, the wavefront control type display device 200 further includes a wavefront control section drive circuit 215 and wavefront control unit 2 16. Signal separator 211 supplies the separated disparity information signal to the moving circuit 215 drive the wavefront control unit.
[0165] wavefront control unit driving circuit 215 is a circuit configuration for driving the wavefront control section 216.
Wavefront control section 216 has a plurality of liquid lens portions 217 that are arranged in a matrix so as to face the image display surface of the two-dimensional image display unit 213, Ru. The details of the configuration of the liquid lens portion 217 thereof is omitted description is the same as the reference of the liquid lens portion 56 described with configuration to FIG. Further, as shown in FIG. 24, one liquid lens unit 217 (in FIG. 24, nine) a plurality of light emitting pixels 214 correspond to, they are arranged such that their emitted light passes.
