Description

The present invention relates to an interactive display device that has a thin large screen and can detect a person in front of the screen and present wind and fragrance to the person via the screen.

In the virtual reality (VR) system, real-time perspective projection conversion of a life-size three-dimensional space model onto a two-dimensional screen realizes motion display and binocular stereoscopic display. is required. In order to realize an intelligent human interface, it is convenient to be able to detect the movement of the user's line of sight and facial expressions in real time. If a gaze point on the screen or a gaze target can be sent to a communication partner in a video conference or the like, the collaboration function can be enhanced.

In the video display, scent presentation and tactile presentation using airflow or wind are effective for enhancing the sense of reality. In order to present a scent or air flow so as to follow a change in an image, it is desirable to control the release of gas based on the position detection of a person.

As described above, in a display device that can change display contents according to the movement of a person or present gas, a function of detecting a person with a non-wearing means and a function of releasing gas from the screen are important.

In response to this problem, the present inventor provided a camera on the back side of the screen, photographed a person through the screen, and detected the position and line of sight of each part of the person, and a gas generator on the back side of the screen And invented a display device having a function of presenting a scent or wind to a person via a screen. In the display device, the object reflected light or the gas can be passed by making the pixels between the screens transparent or making holes between the pixels (Japanese Patent Publication No. WO2008-093721).

However, in this document, there is a negative effect on the technology that configures the screen to be thin and large, and the technology that allows the object reflected light or gas to efficiently pass through the screen in various directions, that is, the video quality. There has been no disclosure regarding a screen configuration technique in which an elongated slit-shaped passage portion that is rarely provided is provided in the screen.

As a technology for forming a thin and large screen, Japanese Patent Publication No. WO2006-100775 discloses a plasma tube array system in which a large number of thin glass plasma tubes are arranged and a resin film with electrodes provided thereon is provided. However, this document does not disclose a technique for photographing a person by providing a camera on the back side of the screen, and a technique for releasing a gas through the screen by providing a gas discharge device on the back side of the screen.

As described above, it is a thin large screen that can detect the movement and line of sight of a person with a camera through the screen, can present airflow, wind, and fragrance from various directions, and there is no display device with excellent manufacturability .

In particular, for a display device using an EL element, a technique for configuring a large screen has not been realized even in the absence of the interactive property.

Special WO2008-093721 Special WO2006-100775

In order to realize a large-screen display device capable of interactive operation, the present invention enables a wide range of observers to be detected by a camera provided on the back side of the screen. In addition, wind and fragrance can be presented via the screen. Specific issues are as follows.

<Means 1>
The display device of the present invention will be described with reference to FIGS.
Display function parts such as a thin tubular or thin strip using a self-luminous body (PLM, EL, LED) or a light shielding body (Liq) (71 in FIG. 1, 72 in FIG. 2, 73 in FIGS. 3 to 8, A screen (10) configured such that 73 in FIG. 10B and 79) in FIG. 10D are arranged at predetermined intervals so that the subject reflected light (28) or the gas (7) passes between the display functional components. And a camera (Cam) that captures the reflected light of the subject through the screen or a gas discharge device (6) that discharges the gas toward the subject through the screen.

The camera (Cam) captures the reflected light (24 to 28) of the subject by invisible light illumination (LgIn) and processes the image to determine the position of the subject (person), the position of the eyes, the position of the nose, the line of sight, etc. It can be detected. Motion detection and binocular stereoscopic display are possible using detection of the eye position. Further, the gas can be controlled to be released to the detection position.

The display function component means a component that performs display so as to divide the screen (10). Between the display function parts (62), a long and narrow gap (slit-like gap) can be provided. By using the plurality of gaps, a gas containing a scent, a warm gas, a cold gas, a humid gas, a strong gas Wind, weak wind, and the like can be emitted toward an observer detected by the camera. Here, the gap means a gap without optical distortion with respect to the passage of light. Therefore, the case where the gap is filled with a transparent material is included. Moreover, with respect to the passage of gas, it means space.

The subject reflected light (24, 28) passes at least between the display function components (62), but in addition to this, it may be configured to pass inside the display function components (71-73, 79).

As means for arranging a plurality of the display function parts in a line, the display function parts (71 to 73, 79) are stuck on a transparent sheet (BS, BS1, BS2) with little optical distortion, sandwiched, or a display function part The space (62) can be filled with a transparent material with little optical distortion. A hole (HL) may be made in the transparent sheet so that light or gas can pass therethrough.

The display function parts (71 to 73, 79) are characterized by high reliability because the light emitter is sealed therein. By using the display function parts side by side, the screen can be configured to be thin, large and inexpensive. In addition, since the screen is thin, a large number of slit-shaped gaps can be provided between the display function components (62). Subject reflected light (24, 28) or gas (7) can pass through the screen in various directions. Accordingly, the light incident on the camera does not change much near and around the optical axis of the camera lens, and a wide range can be photographed brightly. In addition, the gas discharge device can discharge a gas in a wide range or discharge with directivity.

As shown in FIG. 1 (D) and FIG. 3 (D), the display functional parts (71 to 73) have a cross-section with a round shape such as a flat circle or an ellipse, or a triangle or a trapezoid. By doing so, a part of the display functional parts is narrow from the screen front side to the back side, and the back side can be widened. With this structure, the subject reflected light or gas can further pass through the screen in various directions.

<Means 2>
The display device of the present invention will be described with reference to FIGS. 1E, 2, 3, 6, 7, and 10B.
In the means 1, the display function parts (71 to 73) are provided with self-luminous bodies forming a color pixel in a row and arranged in a row, and the display function parts are arranged at a predetermined interval to thereby display the display function parts. An elongated gap (62) is provided between the functional parts, and the subject reflected light (28) or the gas (7) can pass through the gap with a spread in the horizontal direction.

The elongated gap may be configured such that the minor axis is larger than 1/3 of the screen thickness and the major axis is equal to or greater than the screen thickness or the pixel length. In order to make the gap inconspicuous when viewed from a standard viewing distance, it is desirable that the minor axis is 0.25 degrees or less in terms of viewing angle.

<Means 3>
The display device of the present invention will be described with reference to FIG.
In the means 1 or 2, the plurality of display function parts (72) are fixed to the sheets (BS 1, BS 2) so as to be arranged at a predetermined interval, and drive the light-emitting body (PLM) or the light shielding body. Circuits (64, 69) for the above are characterized in that they are integrated and wired so as to widen the object reflection light or gas passage (62).

In the means 3, the drive circuit (64, 69) can be provided in the sheet (BS1 or BS2) or in the display function component (PLM).

<Means 4>
The display device of the present invention will be described with reference to FIGS.
Display function parts (73, 79) such as thin tubular or thin strips using self-luminous elements (EL, LED) or light-shielding bodies (Liq) are arranged in rows at predetermined intervals on sheets (BS, BS1, BS2). The signal input unit of the circuit that drives the self-light-emitting body or the light-shielding body is integrated at the end (78) of the display function component, and is fixed between the display function components (62). An elongated gap is provided in the object, and subject reflected light or gas passes through the gap.

In the means 4, a tubular plasma light emitter (PLM) may be used as the self light emitter. Liquid crystal (Liq) may be used as the light shielding body.

In FIG. 6, the drive circuit (64, 69) for the self-luminous body or the light-shielding body is such that a current flows from the end (78) to the end (78) of the display function component for each pixel (PX). Can be configured. As the number of pixels increases, the number of circuits increases. This can be dealt with by using a multilayer wiring technique or the like.

In FIG. 7, a pixel driving circuit (70) for receiving signals in time series is provided near each pixel, the pixel driving circuit is connected by a common line (75, 76, 69), and current is supplied to each pixel. Can also be operated. The common line can be composed of a control line (76) for supplying a light emission signal to each pixel in time series and a power line (75, 69) for supplying power to each pixel. By using the common line, the number of wiring lines for pixel driving can be greatly reduced.

The pixel driving circuit (70) can be composed of a switching element composed of a MOS transistor or the like and a timing circuit.

In the means 4, the signal current is output from the end (78) of the thin tubular or thin strip-shaped display functional component from the input end (78), that is, the wiring for scanning the pixel constituting the screen is provided in the display functional component. It is provided in parallel and does not need to be provided in a direction orthogonal to the display function component. Therefore, when the display function parts are arranged, a very narrow gap (62) can be provided between the parts, and the reflected light from the subject or the gas can pass in various directions.

<Means 5>
The display device of the present invention will be described with reference to FIGS.
In any one of the means 1 to 4, the display function parts (71, 72) are constituted by using thin tubular plasma emitters (PLM), and the display function parts are arranged at a predetermined interval, whereby the display function parts are arranged. A gap (62) through which subject reflected light or gas passes is provided between the parts.

As shown in FIG. 1, one tubular plasma luminous body may be used as the display functional component (71), or a plurality of tubular plasma light emitters may be used as the display functional component as shown in FIG. For example, three tubular plasma emitters corresponding to the three primary colors of light may be combined into a color display function component (72). When the color display function component is used, the color unevenness is small and the object reflected light or gas passage characteristic is also good.

The display functional parts can be arranged and fixed on the transparent sheets (BS1, BS2) at predetermined intervals to form a screen. The transparent sheet can be provided with a transparent driving circuit for causing the plasma luminous body to emit light. A transparent gap (62) for allowing the subject reflected light to pass therethrough or a space (HL) for allowing the gas to pass therethrough can be provided between the display functional components.

As shown in FIG. 1D, the subject reflected light (24, 28) may be configured to pass not only between the display function parts (62) but also within the display function parts or the light emitting body. This is possible by using a flat circular tube for the plasma emitter container (PLM) and using a plasma emitter transparent to near infrared light.

As shown in FIG. 1D, when the edge of the cross section of the display function component (71) is rounded, the gap (62) when the display function components are arranged is directed from the front side to the back side of the screen. Since it can be configured such that a part is narrow and the back side is wide, the subject reflected light (28) or gas can pass in various directions. That is, the degree of freedom in the passing direction is great. If a camera is provided on the back side of the screen, the subject can be accurately photographed over a wide range. Moreover, if a gas discharge device is provided, gas can be discharged in a predetermined direction.

<Means 6>
The display device of the present invention will be described with reference to FIGS. 3 to 8 and FIG.
In any one of the means 1 to means 4, the display function component (73) is configured in a thin strip shape by arranging electroluminescence (EL) elements or LED elements in a row, and the strip display function components are arranged at a predetermined interval. Thus, a gap (62) through which the subject reflected light or gas passes is provided between the display function parts.

As shown in FIG. 4, the band-shaped display functional component (73) is a transparent thin and long strip glass substrate (b1, b2) provided with EL light emitters in a row and transparent for applying a voltage to the light emitters. An electrode (A, K) is provided, and a lead wire from the electrode can be taken out from the display functional component. The display function parts can be arranged on the transparent sheets (BS1, BS2) at predetermined intervals to constitute the pasting screen (10). As shown in FIG. 6, the transparent sheet (BS1, BS2) can be provided with a drive circuit (64) for the light emitter. Images can be displayed by driving the light emitters in the vertical and horizontal directions. Between the display function components (62), a subject reflected light or gas passage can be provided.

Moreover, as shown in FIG. 6, you may comprise so that the said lead wire (64, 69) may be taken out from the edge | tip (78) of a strip | belt-shaped display functional component. When the band-shaped display functional components are arranged, the subject reflected light or gas passage portion becomes an elongated slit-shaped gap (62). A camera provided on the back of the screen can capture a wide range, and the gas discharge device can discharge gas in various directions.

The EL light emitters provided in the band-shaped display functional component may be arranged in a line by combining three color light emitters constituting a color pixel (EL (PXC) in FIG. 6A). In this configuration, since the three colors are collected, there is little color unevenness. In addition, you may comprise so that to-be-photographed object light may pass not only between display function components (62) but the inside of EL element.

<Means 7>
The display device of the present invention will be described with reference to FIG. 1, FIG. 3, FIG. 9, and FIG.
In any one of the means 1 to 6, the gas (7) is discharged from the screen toward the subject (P) detected by the camera (Cam).

<Effect of means 1>
In the present invention, display function parts such as thin tubes or thin strips are arranged at predetermined intervals to form a screen, so that a thin large screen can be manufactured, and a slit-like gap can be provided between the display function parts. There is an effect of allowing subject reflected light or gas to pass in various directions.

Since the movement of a person can be detected from the image captured by the camera and the information can be fed back to the display, motion vision, binocular stereopsis, etc. can be realized by non-wearing means. In addition, it is possible to present tactile stimulation and scent presentation by wind to the person. Thus, it is excellent as an interactive display device. Further, even when the gap is soiled, the interval is slit and the cleaning liquid passes, so cleaning is easy and maintenance is good.

<Effect of means 2>
In the present invention, subject reflected light and gas are unlikely to pass through the interval unless the pixel gap is increased. However, in the first means, when the interval is increased, color unevenness may occur. On the other hand, the means 2 has the effect of reducing the color unevenness and improving the image quality by arranging the band-like display functional parts having the color pixel rows to form the screen. Further, when EL is used as the self-luminous body, the yield is higher when the three colors are manufactured as one body.

<Effect of means 3>
In the present invention, since the circuit for driving the pixel array is integrated and wired so as to widen the subject reflected light or the gas passage between the display function parts, the camera can capture a wide range, and the gas emission device emits scent and wind. It has the effect of being released far away in various directions.

<Effect of means 4>
In the present invention, a circuit for driving the pixel column is provided in the display function component, and an end of the component serves as a signal input unit. Therefore, most of the interval between the plurality of display function components is reduced by subject reflected light or gas. It can be used as a passing part. Therefore, the camera can shoot a wide range brightly and finely. The gas discharge device can discharge airflow in various directions.

<Effect of means 5>
In the present invention, since the tubular plasma light emitter is used for the display functional component, a thin and large screen can be formed, and a slit-like gap can be provided between the tubular plasma light emitters, so that the subject reflected light or gas varies. Can pass in any direction. Therefore, there is an excellent effect as a large screen interactive display device.

<Effect of means 6>
In the present invention, a thin large screen can be formed because a strip-like body in which EL elements or LED elements are arranged in a line is used as the display function component. In addition, since an elongated slit-like gap can be provided between the display function components, the subject reflected light or gas can pass in various directions. Therefore, there is an excellent effect as a large screen interactive display device.

<Effect of means 7>
In the present invention, a wide range can be photographed finely with a camera on the back side of the screen, and a person can be detected with high accuracy. The gas discharge device can present fragrance and wind to the person with high accuracy. Therefore, there is an excellent effect as a large screen interactive display device.

Embodiments of the present invention will be specifically described.

FIG. 1 shows an embodiment of the present invention in which a screen 10 is configured by arranging display functional parts 71 using a tubular plasma luminous body PLM at predetermined intervals. 1A is a cross-sectional view of the display device, and FIG. 1B is a front view. Cam is a camera provided on the back side of 10, CCD is an image sensor, and LgIn1 is a concentric (doughnut-shaped) near-infrared illumination device as shown in FIG. Alternatively, it can be made of an LED or the like. The camera can photograph the front through the screen 10. Reference numeral 1 denotes a camera drive control device, 2 denotes an illumination drive control device, 3 denotes an information processing device, and 4 denotes a video control device. 6 is a fragrance generating device or airflow generating device, and 5 is a gas control device for controlling 6.

The configuration of the screen 10 will be described. In FIGS. 1A and 1B, the display functional component 71 is configured by one PLM. In the PLM, a plasma luminescent material is provided in a thin tube, and a transparent electrode (ITO) for applying a voltage to the light emitter is provided outside the tube. The plurality of PLMs are fixed at predetermined intervals so as to be sandwiched between the transparent sheets BS1 and BS2. Drive circuits 64 and 69 for applying a voltage to the transparent electrode are provided on the sheets BS1 and BS2.

In the single PLM in the figure, a portion to which a voltage is applied in the vertical direction emits light in a predetermined color, and becomes a pixel PX. PLM-B, PLM-G, and PLM-R are tubular plasma emitters that emit blue, green, and red light, respectively. When these three are combined, a color pixel PXC can be configured.

Since PLM can be manufactured with a thickness of about 1 mm and a length of several meters, a large screen can be configured by arranging them. Here, the transparent electrode can be provided on the transparent sheet by a printing technique. The sheet BS2 on the back side of the screen is provided with a member Ref-BGR that reflects or blocks visible light and allows near infrared light to pass through.

62 is a PLM interval. The light 21 of the near-infrared light illumination device LgIn1 is irradiated onto the subject P via the screen, and the subject reflected lights 24 and 28 are captured by the camera Cam via the screen. FIG. 1D is an enlarged view of the display functional component (PLM) 71. If the cross section of 71 is made flat and round as shown in the figure, the display function parts can be partially narrowed from the screen front side to the back side, and the back side can be widened. With this structure, the subject reflected light 28 or gas can further pass through the screen in various directions. Therefore, the camera can capture a wide range.

Further, by making the PLM transparent at the near-infrared wavelength, the subject reflected light 24 that passes through the PLM, that is, the display function component 71 is also captured by the camera Cam. Further, by making the cross section of the PLM a flat circle, the visible light emitting surface becomes large and a bright image can be displayed.

A camera lens (Lens) is provided close to the screen 10. If the screen 10 is sufficiently close to the shortest focal length Fc-Lim of the camera lens Lens, the PLM that is the screen structure can capture the subject P without being reflected in the image. In addition, as described above, the PLM can be configured to be transparent in the near infrared, and in this case, a brighter subject image can be obtained. Here, Fc is the focal length to the subject, and Fc is sufficiently far compared to Fc-Lim.

As another method for holding the display function component 71 at a predetermined interval, the interval 62 may be filled with a transparent resin. Further, as shown in FIG. 1E, the three PLMs constituting the color pixel PXC are collectively used as the display function component 72, arranged at a predetermined interval with 72 as a unit, and the interval 62 is set as the subject reflected light passage unit. It may be.

Further, holes HL may be provided in the sheets BS1 and BS2 that hold the PLM at predetermined intervals so that the subject reflected light or gas can pass therethrough. In the region indicated by 68 in FIG. 1B, a large number of small holes HL for allowing gas to pass therethrough are provided. A fragrance generating device or an airflow generating device 6 can be provided on the screen back side of this region. A person in front of the screen can be detected, and scent or airflow 7 can be presented to the person.

The tubular plasma element may be replaced with another light emitting element such as an EL element or an LED, as will be described later with reference to FIGS. 3 and 10B. The screen 10 of the present invention is large but thin and can be configured with a thickness of about 1 mm to 10 mm.

The screen 10 according to the present invention can emit various geometric pattern light because invisible illumination light having a near infrared wavelength or more efficiently passes between pixels. The illumination device LgIn1 emits near-infrared light having a wavelength of 800 nm or more or infrared light. By projecting the pattern light and capturing the subject reflected light and the corneal reflected light of the pattern with a camera, a pupil image and a corneal reflected image can be detected. A person's viewpoint and line of sight can be detected using the detection result.

FIG. 2 shows a second embodiment of the present invention in which three thin tubular plasma emitters constituting color pixels are used as the display functional component 72. (A) is a front view. Only differences from FIG. 1 will be described. PLM-B, PLM-G, and PLM-R are integrally formed in close proximity. It is bonded so as to be sandwiched between the transparent sheets BS1 and BS2. The PLM becomes a pixel PX by partially emitting light, but since the three colors are close to each other, the color pixel PXC has little color blur.

A solid line 64 is a horizontal driving circuit provided on the front transparent sheet BS1, and a broken line 69 is a vertical driving circuit provided on the back transparent sheet BS2. A voltage is applied to a portion where the horizontal line and the vertical line intersect, and plasma is emitted. By sequentially applying a voltage to each line, an image can be displayed by scanning the entire screen. 69 may be provided directly on the PLM tube wall.

FIG. 2B shows the transparent sheet BS1. A (ITO) is a transparent anode electrode that applies a voltage to the PLM. A, 64, and 69 can be configured using an ITO film (Indium Tin Oxide) or the like. Reference numeral 64 is integrated and wired so as to widen the space 62 between the display functional components 72 that serve as a passage for subject reflected light or gas. An elongated hole HL can be provided by the approach of the three 64 in the 62 region.

FIG. 2C is another example of BS1. 64 is further integrated in the region 62, and the hole HL is further elongated. By providing a large number of slit-like elongated holes, the object reflected light and gas pass efficiently. Further, when cleaning the screen, the cleaning liquid is easy to pass through the hole, so that the cleaning is easy.

FIG. 3 shows a third embodiment of the present invention in which a band in which EL elements are arranged in a row is used as the display function component 73. FIG. (A) is a cross-sectional view of the display device, and (B) is a front view. Compared with FIG. 1, the configuration other than the screen 10 is the same.

The configuration of the screen 10 will be described. FIG. 3E shows a configuration example of the display function component 73. Strip-shaped thin transparent bodies b1 and b2, for example, three color EL light emitters (EL-B, EL-G, and EL-R) constituting the color pixel PXC are arranged in a glass plate in a vertical direction. Provided with a transparent electrode and a drive circuit for applying a voltage to each of the light emitters, and a lead wire for signal input provided outside. Reference numeral 69 denotes a vertical driving circuit and lead wires. Techniques such as those shown in FIGS. 4 and 5 described later can be applied to this structure. Since 73 can be manufactured with a width of 1 mm to several mm, a thickness of 1 mm or less, and a length of several meters, a large screen can be configured by arranging them. 73 Since the area of each one is small, the manufacturing yield is high.

In the figure, the color pixels PXC are arranged in a row in the vertical direction, but a plurality of rows may be provided as long as they can be manufactured. That is, 73 may be configured to display a partial video.

In FIG. 3A, a plurality of 73 are sandwiched and bonded from both sides by thin transparent sheets BS1 and BS2 and held at a predetermined interval 62. Reference numeral 64 denotes a circuit for driving each pixel in the horizontal direction, or an electrode therefor. By controlling the light emission of each pixel PXC with 64 and 69, 10 becomes a display screen. The transparent sheet BS2 on the back side of the screen is provided with a member Ref-BGR that reflects or blocks visible light and allows near infrared light to pass. The subject reflected lights 24 and 28 by the LgIn1 illumination light 21 pass through 62 and are captured by the camera Cam. Moreover, the fragrance and the airflow 7 are presented to the person by the gas discharge device 6 installed on the back side of the screen 10.

As shown in FIG. 3D, when the cross section of 73 is flattened, the distance 62 between the 73 is narrower in the center from the screen front side to the back side and wide on the back side. Can pass 62 at an angle. Therefore, the camera Cam can photograph a wide area brightly. Further, when the display function component 73 that is transparent in the near infrared is used, the subject reflected light 24 can travel straight on the flat surface 63 of the 73, so that a bright camera image can be obtained.

As shown in FIG. 3B, a hole HL can be provided in BS1 and BS2 to allow subject reflected light and gas to pass therethrough.

FIG. 4 shows a configuration in which a white organic EL element and a color filter are used for the display function component 73 in the display device of FIG. FIG. (A) is a sectional view of the apparatus. On the thin transparent glass substrate b1, a drive circuit DV using a TFT (Thin Film Transistor) as a switching element is formed. IS is an insulating film. The color filters Fil-B, Fil-G, and Fil-R are formed thereon, the transparent anode A (ITO) is formed thereon, and the white light emitting layer EL-W is formed on the A, A transparent cathode K (ITO) is formed thereon.

The light emitting layer of the present invention is not limited to white, and a low molecular laminate type, a single layer polymer dispersion type, or the like can be applied. As the light emission phenomenon, fluorescence from a singlet excited state and phosphorescence from a triplet excited state can be used. As the low molecular light emitting layer, aluminum complexes, anthracenes, indium complexes and the like can be applied. A rare earth metal complex may also be used. As the polymer light emitting layer, pi-conjugated systems, polyphenylene vinylenes, polyfluorines, dye-containing polymer systems, and the like can be applied.

Although not shown in FIG. 4A, in the case where a low molecular system is used for the light emitting layer (EL-W), a hole injection layer and a hole transport layer are provided between A and the light emitting layer to emit light. An electron transport layer and an electron injection layer can be provided between the layer and K. The light emitting element is preferably stacked in the order of A, hole injection layer, hole transport layer, light emitting layer, electron injection layer, and K.

A film Ref-BGR that reflects or blocks visible wavelength light and allows near-infrared light to pass through is provided on K (ITO), and a thin transparent body b2 is provided thereon. b2 is a transparent sealing film or protective film that prevents moisture from entering from the outside. The sealing effect can be enhanced by repeating the formation of several pairs of a polymer film and an oxide film. As the oxide film, silicon dioxide (SiO2) or the like can be used.

PX indicates one color pixel (sub-pixel). PA can be made transparent by a partition that separates pixels. Even if the thickness of the display functional component 73 is thick from 1 mm or less as a whole, it can be manufactured with several mm. The plurality of 73 are held so as to be sandwiched between the transparent sheets BS1 and BS2 and constitute the screen 10. A slit-like gap 62 is provided between 73.

In the figure, Ref-BGR is provided immediately above K. However, the position is not limited as long as it is the back side of the light emitting layer. That is, it may be a part of BS2. Further, it may be provided in the camera lens system or in front of the CCD.

PW is a power source. When a voltage is applied between A and K, EL-W emits white light. The voltage applied to PX can be individually controlled by the drive circuit DV. The white light becomes light of three colors by the color filter. Reference numerals 11, 12, and 13 denote blue, green, and red light, respectively. A color pixel is composed of three colors. Although not shown in the figure, a blue-green filter may be added to form a color pixel with four colors (four PXs).

The drive circuit of FIG. 4 is an active matrix type, but a passive matrix type drive circuit that crosses the anode and the cathode vertically and horizontally and sequentially selects the intersection to emit light may be used. In particular, when a large screen is configured, a system in which the screen area is divided and each is passively driven is desirable.

LgIn is an illumination device provided on the back side of the screen 10 and emits near-infrared light (invisible light) 21 toward the front side through the screen to illuminate a person. It can be composed of an EL element or an LED element. LgOut is an illumination device provided outside the screen 10 to illuminate a person by emitting light 20 from visible to near infrared. Use as necessary with incandescent lamps (bulbs) provided on the ceiling, walls, etc. of the room.

Reference numerals 24 to 28 denote subject reflected light that passes through the screen 10. 28 passes between the display functional parts 62. 25, 26, and 27 pass through blue, green, and red elements, respectively. 24 passes through the partition wall PA. These lights are blocked in the visible wavelength range by Ref-BGR, and only near-infrared light passes through the camera lens Cam1 (Lens) and forms an image on the CCD. Therefore, the light contributing to the subject image is near-infrared light among the light emitted from LgIn or LgOut.

The screen 10 can transmit near-infrared light over the entire surface, but there may be a region where light does not partially pass through depending on the pixel structure. As shown in the figure, when the camera lens Cam1 (Lens) is brought close to the screen, the component does not form an image on the image sensor CCD. Only subject reflected light forms an image.

The EL element structure in FIG. 4A is a bottom emission type in which light is emitted from the side where the driving circuit DV is provided, that is, the anode side, but the portion where the driving circuit is formed does not emit light, so In some cases, the space (light emitting area ratio) that shines is as small as about 20% to 40%. In order to solve this problem, a top emission type EL element that emits light from the cathode side may be used.

In FIG. 4B, EL-W1 and EL-W2 are examples of emission spectra of white phosphorescent organic EL elements. The horizontal axis indicates the wavelength, and the vertical axis indicates the relative value of the light intensity. Although there are differences depending on the material, a light emitter having a wavelength of about 400 nm to 700 nm can be used. Ref-BGR is a characteristic example of a film that reflects or blocks visible light and allows light exceeding the human visible limit wavelength (HV-Lim) to pass. The vertical axis represents the relative value of the light transmission rate. Although HV-Lim has individual differences, for example, it can be 830 nm or more. At wavelengths above 900 nm, most people do not perceive light. The margin may be set to 900 nm or more with a margin. LgIn is a light emission wavelength characteristic of a lighting device using a near-infrared light emitting diode (LED-IR), and LgOut is a light emission wavelength characteristic of an external lighting device. The vertical axis represents the relative value of light intensity.

In FIG. 4C, Fil-B, Fil-G, and Fil-R each indicate the wavelength pass characteristics of the color filter. The vertical axis represents the relative value of the light transmission rate. In the figure, Fil-B allows light having a wavelength of about 370 nm to 520 nm and light having a wavelength of 800 nm or more to pass centering on about 450 nm and blocking the others. The Fil-G transmits light having a wavelength of about 470 nm to about 650 nm and light having a wavelength of 800 nm or more with the center at about 550 nm, and blocks the others. The Fil-R allows light having a wavelength of about 590 nm or more to pass therethrough and blocks light below that.

White light becomes blue, green, and red light by the filter. The wavelength ranges of the light 11, 12, and 13 from the EL element of FIG. 4A are the light (AK-B, AK-G, and AK-R) that passes through each filter in FIGS. ). The camera Cam captures light having a wavelength of 840 nm or more by Ref-BGR.

FIG. 4D is an enlarged view of the wavelength HV-Lim before and after FIG. 4B. The white EL element desirably emits light only in the visible range, but some elements have a spectrum to some extent in the near-infrared wavelength range, such as EL-W2. In the white phosphorescent organic EL element, the emission color changes depending on the current density, and the intensity in the near-infrared wavelength region around 800 nm may be relatively high.

Even in such a case, in the present invention, since Ref-BGR is provided, most of the light in the wavelength range is blocked, and the amount of light Leak leaking to the sensitivity region of the camera is extremely small. Therefore, the subject image is not affected. As described above, in the present invention, by selecting an EL material, visible light for displaying an image can be emitted only forward, and near-infrared light for subject detection can be captured by a camera.

FIG. 5 shows a configuration in which organic EL elements that emit blue, green, and red light are used for the display function component 73 in the display device of FIG. FIG. (A) is a sectional view of the apparatus. A different point from FIG. 4 is demonstrated. EL-B, EL-G, and EL-R are EL elements each having the emission wavelength characteristics shown in FIG. For example, EL-B has a peak at about 465 nm, EL-G has a peak at about 525 nm, and EL-R has a peak at about 635 nm. The vertical axis represents the relative value of the emission intensity. Since the EL element itself emits light of the three primary colors, a color filter is not necessary.

LgIn is an illuminating device provided so as to overlap the back side of the screen 10 and is composed of an organic EL element having a near-infrared light emitting layer EL-IR. As shown in FIG. 5B, EL-IR has a material with a wide emission wavelength range. However, a member (filter) ReF-BGR that reflects or blocks visible light and allows non-visible light of 840 nm or more to pass therethrough. Is used before LgIn and is not perceived by humans.

For the blue (B), green (G), red (R), and near infrared (IR) light emitting layers, EL materials such as low molecular weight, high molecular weight, and rare earth light can be applied. When a rare earth is used for the light emitting layer, light having only a necessary wavelength spectrum can be emitted, so that color characteristics are good.

FIG. 6 shows a fourth embodiment of the present invention, in which a band in which EL elements constituting a color are arranged in a row is used as the display function component 73. FIG. 1A is a front view of a display device. A different part compared with FIG. 3 is mainly demonstrated.

In the screen 10, three rows of strip-like display functional parts 73 are provided. 73, color pixels PXC are arranged in a column in the vertical direction. 64 (ITO) is a horizontal transparent drive circuit, but all the lead wires are integrated on the end 78 of the display function component. Reference numeral 69 (ITO) denotes a vertical transparent drive circuit. Since all the lead wires are integrated in the longitudinal direction of 73, when 73 are arranged, an elongated gap 62 can be formed between 73. The object reflected light can pass through 62.

FIG. 6B shows a configuration of the transparent sheet BS1 for holding the display function component 73 at a predetermined interval. Reference numeral 74 denotes an area where 73 is provided. 74 is provided with a hole HL for allowing subject reflected light and gas to pass therethrough. In this invention, since an aperture ratio can be raised, gas passes efficiently. Moreover, since the screen is thin, the gas can pass in various directions such as a horizontal direction and a vertical direction. A person can be detected and a scent or airflow can be presented in that direction.

FIG. 7 shows a fifth embodiment of the present invention, in which a band in which EL elements constituting a color are arranged in a row is used as the display function component 73, and a common line is used in the drive circuit. FIG. 7A is a front view of the display device. Differences compared to FIG. 6 will be mainly described.

75 (ITO) is a transparent common line for supplying power. It is connected to the EL element via the pixel driving circuit 70 and connected to 69. 70 has a switch function that can open and close the circuit in time series by a signal. When the circuit is open, current flows from 75 to 69. As described above, since the signal input portion of the drive circuit is integrated at the end 78 of the display function component 73, an elongated gap can be provided between the display function components 62.

FIG. 7B is an enlarged view of the light emitter driving unit. Three blue EL elements (EL-B1, EL-B2, and EL-B3) as light emitters are arranged in the vertical direction. An LED may be used instead of the EL element. 76 (ITO) is a transparent signal line that controls opening and closing of the pixel drive circuits 70-1, 70-2, and 70-3. 70 is composed of a MOS transistor or the like, and performs timing adjustment and switching.

7C and 7D are diagrams for explaining the operation 70. The horizontal axis t is time. (C) shows an example of a signal flowing through 76, and (D) shows 70 open / closed states. A trigger signal 77 is sent from 76 to 70. 70-1 opens the switch for a predetermined time after the time T1. In the figure, it is shaded. When the switch is open, a signal EL-B1 for operating the EL element is sent from 76. By this signal, current is supplied to the EL element (EL-B1) for the shaded time as indicated by the numeral 1.

The same applies to 70-2 and 70-3. After receiving the trigger signal 77, the switches are opened for a predetermined time indicated by shading after the times T2 and T3, respectively. As indicated by the numerals 2 and 3, current is supplied to the EL elements (EL-B2, EL-B3) during this predetermined time. In the present invention, the number of wiring lines for pixel driving can be greatly reduced by using a common line.

FIG. 8 shows a sixth embodiment of the present invention, in which a band in which EL elements constituting a color are arranged in a plurality of columns is used as the display function component 73, and a common line is used in the drive circuit. FIG. 8A is a front view of the display device. Differences compared to FIG. 7 will be mainly described.

Display functional parts 73-1 and 73-2 using EL elements are arranged in the horizontal direction between the transparent sheets BS1 and BS2. The common lines 75 and 69 constitute a drive circuit for each pixel. Each display functional component is provided with two color pixel rows, and a hole HL is provided between them. As described above, the display functional component may have a plurality of color pixel columns. An elongated hole HL is provided between 62-1 and 73-2. Since many wide holes are provided in the horizontal direction, the gas passage characteristics in the horizontal direction are good. By arranging 73, a large screen can be configured.

8B and 8C are diagrams illustrating the operation of the pixel drive circuit 70. FIG. A trigger signal 77 is sent to 70 from the common line. 70-1 opens the switch for a predetermined time after time T1. In the figure, it is shaded. When the switch is open, a signal EL-B1 for operating the EL element is sent from 76. By this signal, current is supplied to the EL element (EL-B1) for the shaded time as indicated by the numeral 1. The difference from FIG. 7D is that the shaded time is lengthened by giving the switch an operation holding characteristic. In this way, the screen is brightened by operating the light emitter for a long time.

FIG. 8D shows a method for manufacturing the display functional component 73. Since an extremely thin and elongated strip-like glass plate b1 is used, the glass substrate b1 can be wound around a roll R. An EL element is formed in a portion where the glass plate between the rolls is extended, and the film is wound while the protective film b2 is attached. When forming a screen, this band can be cut into a predetermined length and used as a display functional component.

FIG. 9 is a seventh embodiment of the present invention, which is a display device with a large curved screen and its application. In FIG. 9A, a screen is provided so as to surround a person, and a plurality of cameras are directed to a predetermined area where the person is present so as to be congested. An example using the curved screen 10, FIG. 9B is a top view of the example.

The screen 10 is configured by arranging display functional parts using EL elements, light emitting diodes, and the like. Reference numeral 56 denotes a predetermined observation area near the center of curvature of 10, and it is assumed that the user P is in the area. On the back side of 10, a camera Cam-x (x = 1 to 4) with illumination similar to that shown in FIG. 1 is provided. In front of the camera, a member Ref-BGR that reflects or blocks visible light and allows near-infrared light to pass through is provided. Near-infrared illumination devices LgIn3-x (x = 1, 2) are provided at the left and right ends of the screen. In addition, an air gun scent generator 6-x (x = 1 to 2) is provided. Cam-x and 6-x are directed to 56.

The user P can perceive the display target Obj-Px (x = 1 to 3) stereoscopically by wearing the binocular stereoscopic glasses 48. This figure shows a concert being watched. A visual field range of 100 degrees or more can be realized. Further, it is possible to create a scent space by detecting that the user is in the region 56 with the camera and causing the plurality of scent vortex rings 7 coming out of 6-x to collide with each other. High sense of presence is obtained by visual, auditory, and olfactory displays.

Next, the reason why it is possible to detect a gaze with high accuracy by allowing a large eyeball rotation by using the screen and the camera as described above. In FIG. 9B, 21 is near-infrared illumination light, and 24 and 28 are subject reflected light. The reflected light is photographed by each camera Cam1-x. Here, consider a case where the user P is facing the front of the screen and looking at Obj-P3 with a horizontal eye (line of sight Gaze).

In the Cam-2 or Cam-3 image in front of P, since the eyeball is greatly rotated, the pupil image is distorted into an ellipse, and the deviation del between the pupil center and the center of the cornea reflection image is large. When this image is used, the process of obtaining the center of the ellipse is complicated, and if the eyeball rotation angle θ is too large, the relationship between θ and del is not linear. Therefore, it is difficult to obtain high gaze detection accuracy.

However, since Cam-4 captures the eyeball from the front, the pupil image is close to a circle and the del is small, so that the line of sight Gaze can be accurately detected with a simple algorithm using a relatively inexpensive camera. As described above, in this embodiment, it is possible to realize high eye-gaze detection accuracy by selectively processing a camera image obtained by capturing an eyeball near the front. Specifically, if a camera equipped with an image sensor of about 4 million pixels is used, 56 is a range of 1 m square from a standard observation point, an eyeball rotation angle is about 40 degrees left and right, and a line of sight of about 1 to 2 degrees. Detection accuracy is obtained.

As a method of selectively processing a Cam-4 image from a plurality of camera images, del is calculated in each camera image, and an image having the smallest del is selected. Alternatively, in the next-line gaze detection, a camera image in the immediately previous gaze detection direction may be preferentially processed.

The above effect will be compared with FIG. 9F in which the camera is installed in parallel. Also in this figure, the camera that captures the eyeball in front is Cam-4, but the eyeball cannot be captured unless the field of view is wide. However, if the camera has a wide-angle field of view, a high-resolution lens system and an image sensor are required, and it is difficult to realize at low cost.

In FIG. 9C, the screen 10 is configured so as to surround the predetermined area 56 by connecting three plane screens, and the field of view of the three cameras Cam-x (x = 1 to 3) is directed to 56. It is an example.

FIG. 9D shows an example in which the flat screen 10 is used, but the field of view of the three cameras Cam-x is directed to 56.

FIG. 9E shows an example in which five cameras Cam-x with near-infrared illumination devices are provided on the screen 10 curved in the horizontal and vertical directions, and a large circular illumination device LgIn3 is provided at the edge of the screen. . The subject can be photographed brightly and finely without shadows.

FIG. 10A is an example in which the wall of the room is used as a display screen in the eighth embodiment of the present invention and used as a media room. In the figure, reference numerals 10-1 to 10-5 denote display screens. A number of cameras Cam are provided on the back side of the screen, and a person is detected via the screen. Reference numeral 6 denotes a gas discharge device installed on the back side of each screen, which can create a flow of fragrance (Frg) and air (Air) from wall to wall through the screen.

FIG. 10B is a front view of the display screen 10-4. An example in which a light emitting diode (LED) is used as the display function component 73 is shown. On the belt-shaped substrate, the components made up of pixels of LEDs that emit three colors of visible light and near-infrared light are arranged, and the drive circuits 64 and 69 are configured to take out lead wires from the end 78 of 73. Yes. FIG. 10C is an enlarged view of the component. LED-B, LED-G, LED-R, and LED-IR are light-emitting diodes that emit blue, green, red, and near-infrared light, respectively. The plurality of 73 is fixed to the transparent sheet BS at a predetermined interval, and constitutes the screen 10. An area for allowing the subject reflected light or gas to pass therethrough is provided between 73. HL is a slit-like elongated hole through which gas passes.

FIG. 10C shows an example in which the liquid crystal element Liq is used as the display function component 79. The liquid crystal is used as a light shield. If a screen is configured by arranging the 79 in a large number of rows and the screen is used as a wall of a room, a multifunctional electronic curtain is obtained. A pattern can be displayed on the curtain using external light, or external light can be blocked. Since the screen has a hole, it cannot be completely darkened, but the amount of external light can be controlled. Since air passes, it can take in wind.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention in the implementation stage. Further, the above-described embodiments include various stages of the invention, and may be implemented by an appropriate combination.
