Abstract

Passive diffuser frame uses light emitted from a video display front face to produce cold emission ambient lighting effects, having a light guide capturing display image light and in optical communication with a distributive outer frame that redirects that light. The ambient light can be diffused, non-image forming, directed as spill light or to a light pipe. A goniophotometric element or a goniochromatic element allows changing intensity or color of ambient light as a function of viewing angles. The light guide can use a prism splitter or partial reflector, to redirect light and allow viewing the original display image simultaneously. Additional and subtractive color mixing and photoluminescent substances allow new chromaticities, including fluorescent colors and new colors outside of the gamut of output light colors in per se producible by the unaided video display unit.

Description

Utilize video display unit to carry out the passive diffuser frame system of ambient lighting as light source

Technical field

The present invention relates to the product of a kind of video display and ambient lighting effect thereof.Especially, the present invention relates to utilize the video display light to carry out the passive diffuser frame system of ambient lighting as light source, the conversion that this system comprises the space of display light and colourity is so that the effect that can not be provided by conventional video display unit or printing opacity equipment to be provided.

Background technology

The engineer has explored for a long time and has widened by consuming video capacity, for example by enlarging screen and projected area, for 3 dimension effects modulation sound true to nature, and improvement video image, comprise wideer video colour gamut, resolution, and aspect ratio, for example have high definition (HD) Digital Television and video system and the sense that obtains.In addition, film, TV and video product also attempt to utilize audio-visual equipment, for example by using color, scene cut, visual angle, scene and area of computer aided diagrammatic representation on every side to influence spectators' impression dexterously.This point also will comprise the theatrical stage illumination.Illuminating effect for example usually is recorded synchronously with video or performance scene, and reproduces under the help of instrument or computer, and this instrument or computer are programmed to the suitable scene drama that scheme with the expectation of utilizing is encoded.Illumination is in the scene, and is normally impossible to the fast-changing automatic adaptation in not plan or the Unrecorded scene especially usually.

PHILIPS Co. (Holland) and other company disclose and have been used to change environment or ambient illumination to increase the device of typical family or the commercial video capacity of using, but relating to, this point utilizes traditional light source, and the improved script of the illuminating effect of expectation or some classifications of coding.Using of this script and conventional light source is always impossible or not desired as people.

This invention utilizes passive framework photoconduction and photophore, utilizes and produces light atmosphere and luminous effect from the video captured display light of video display unit own.Video display unit can be with using any technology or platform, for example CRT (cathode ray tube), LCD (LCD), PDP (plasma display), FED (electroluminescent display) or other technology.For the transmission of video or visual information even can use any transmission medium, for example can find in the window of building.In order clearly to discuss, use video display schematically to illustrate herein.

Sense is undoubtedly the born in a certain respect a kind of function of human vision, and sensation that its utilization is very complicated and nerve fiber produce the perception to color and luminous effect.The mankind can distinguish about 10,000,000 kinds of different colors.In people's eyes, receive or light adaptation power for color, exist three groups to be approximately 2,000,000 sensation bodies that are called cone, they have sharp cutting edge of a knife or a sword value 445,535 and 565nm, and have a large amount of crossovers the absorption of light wave distribute.These three kinds of cone types form so-called trichromatic system, are called B (blueness), G (green) and R (redness) for historical reasons; This point cutting edge of a knife or a sword value unnecessary with display in any primary colours of using, for example normally used RGB phosphor is corresponding.For the low-light body, or also there is interaction in the so-called night vision body that is called rod.Human eyes typically have 100,012,000 rods, and this has influence on visual experience, especially for the low-light (level) state that for example finds in home theater.

Set up the principle that color video is based on human vision, and three looks of known human vision and channel opposing theory us have been joined and have seen desired color and the understanding that has the effect of high-fidelity for original or predetermined picture for how influencing eyes.In the color mode and space of majority, three-dimensional or coordinate are used to describe human visual experience.

Color video definitely depends on metamersism, and it utilizes the generation of the reference stimuli permission color sensation of peanut, rather than the actual light of desired color and character.Like this, in the mankind's brains, utilize limited number purpose reference stimuli, the whole colour gamut that known RGB (red, green, blue) trichromatic system of for example using is come reproducing color therewith in whole world rabbit.For example, by produce the redness and the green light of number about equally in each pixel or pixel, nearly all video display shows that yellow scene light is known.Pixel is less for the solid angle that they face toward, and eyes are deceived and the perception yellow; And be not the green or red of its actual propagation of perception.

The method that has multiple color mode and definite color comprises that known CIE (Commission Internationale De L'Eclairage (Commission Interationale de I ' eclairage)) color corridinate system is used to describe and the color of definite rabbit.In this is open, get rid of display or the color space is used double-colored or four colour systems system, or produce the system of multiple reference stimuli without any thing.Can use the color mode of any number in the present invention, comprise opposition color space, for example CIEL*U*V* (CIELUV) or CIE L*a*b* (CIELAB) system of using.The CIE that is built in 1931 is a mechanism for all color managements and reproduction, and its achievement is to utilize the chromaticity diagram of x, y and three coordinates of z.The zone of high-high brightness is generally used for describing color according to x and y in this three dimension system, and is called 1931x, and this zone of y chromaticity diagram is believed to describe all colours of human perception.This just and color rendering formed significant contrast, metamersism is used to deceive eyes and brain in color rendering.Use today multiple color mode or space to be used for wherein having ISO RGB, Adobe RGB, NTSC RGB to wait reproducing color therewith by using three-dimensional three primary colors or phosphor.

Yet, notice that this point is very important, utilize promptly that the video system of these trichromatic systems shows might color scope be limited.NTSC (international television standard committee) RGB system has the available color gamut of relative broad, but half of all colours of human perception only can be reproduced by this system.Utilize the feasible scope of conventional video system can not sufficiently give multiple blueness and purple, blue-green and orange/redness.

In addition, human vision system has been endowed the ability of compensation and identification, is necessary to its understanding for any video system of design.Human color appears in the various modes of performance, and target pattern and light-emitting mode are wherein arranged.

In target pattern, the light that light stimulus is sent from light source as target reflection and perceived.In light-emitting mode, sight stimulates perceived as light source.Light-emitting mode is included in the stimulation in the complex domains, and this stimulation is brighter than other stimulation.It does not comprise as light source, for example known stimulation of video display, and its brightness and illumination are less than or equal to the scene of eyesight or whole brightness in zone, thereby make this stimulation show as target pattern.

Especially, there is the multiple color only appear in the target pattern, wherein, brown, olive colour, chestnut color, grey and shallow brown yellowish pink.For example do not exist such as object, for example the traffic sign lamp of brown as the brown light emitting source.

For this reason, the direct light source of additional utilization of attempting to increase the video system of color of object can not be accomplished this point.Can not reproduce brown or hestnut color in the azarin of nearly scope and the combination of green LED (light-emitting diode), this point has limited selection to a great extent.Only the spectral color at the brightness rainbow different with saturation can reproduce by the Direct observation of illuminating source.

Therefore it is preferred that available colour gamut surpasses traditional light source.The possible colour gamut that enlarges the system's reproduction frequently of typical trichromatic vision also is preferred.At last, also wish to send to by modulation or change the color of video user, develop the characteristic of human eyes, for example the relative brightness of different colours is as the change of the function of intensity level.

With reference now to Figure 10-12,, it shows another embodiment of the present invention, and wherein passive diffuser frame P has the function of angle measurement luminosity.Figure 10 illustrates this embodiment of the present invention, wherein the passive diffuser frame of Fig. 9 is equipped with one type angle measurement luminosity element PN, is depicted as cylindrical prism or lens in the external frame PF that is formed on, is integrated in or insert photoconduction PG and/or distribution here.This allows special effect, and promptly the characteristic of the surround lighting M of Chan Shenging changes as the function of spectators' position.The outward appearance of passive diffuser frame P and display D is illustrated among Figure 11, and as shown in Figure 6 similar wherein shows the front schematic view of passive diffuser frame of the angle measurement luminosity of Figure 10.As directed display D sends original display imaging 1.If the external frame PF of the distribution with diffuser core or characteristic is arranged, the non-imaging 3 of the framework shown in surround lighting M takes, and the form of the non-imaging angle measurement of the framework luminosity light 4 that also produces with the angle measurement luminosity element PN shown in the sectional view of Figure 10.The effect of this optical form as can be seen from Figure 12, Figure 12 illustrates the passive diffuser frame of Figure 10 again, and the effect of angle measurement luminosity is shown, this effect provides the different brightness of the non-imaging angle measurement of framework luminosity light 4 and characteristic as function of viewing angle.As directed, show that output light K enters cylindrical prism or angle measurement luminosity element PN by photoconduction PG.Shown in the sample ray in, only anisotropically change direction-as directed from angle measurement luminosity element PN, depend on inlet point on the cylindrical surface of cylindrical prism-as directed, with the spectators of the as directed advantage point that mediates or human viewer Q will than under observer-Q and observer+Q of top brightness of receiving different angle measurement luminosity element PN.For example, this effect can allow user or spectators to see the effect that stands from chair, or allows the user to make the light that a little adjustment is different from angle measurement luminosity element PN with the optical power level that obtains to receive or brightness for the observation place.Based on the little change of observation place, this allows to change based on the personal preference brightness of the surround lighting of generation.Can use other optic shape and form, comprise rectangle, triangle or erose prism or shape, and they can place as expected or be integrated on the external frame PF of distribution.Be different from isotropic output, here the effect of Huo Deing may be the wave band of interested light that projects wall, object on every side and be positioned at the surface of display D, makes a kind of light be presented in the black room variation as situation elements, color and brightness on the display.The number of operable angle measurement luminosity element and type almost are unlimited, comprise polylith plastics, glass and the visual effect of being produced by the manufacturing technology that etching and appropriateness are destroyed.For different stagewises, passive diffuser frame P can be unique, even also can exchange.

With reference now to Figure 13-16,, shows a plurality of interchangeable embodiment of photoconduction and distribution.Figure 13 illustrates the similar passive diffuser frame with Fig. 9, but utilizes the partial interior reflection so that the free of losses break-in of passive diffuser frame P interior lights to be provided.In this embodiment, form photoconduction PG and be used to provide the critical surfaces that 100% internal reflection takes place thereon, this point is described in the explanation of Figure 18 below in more detail.This point, as show that output light K enters photoconduction PG, the multi-direction light of part that by chance surpasses the internal reflection critical angle is changed direction, become as directed internal reflection output light KX by internal reflection, and other the multi-direction light that shows output light K remains under the critical angle, the quilt shown in becoming by photoconduction PG transmits or the output light KT of deflection not.Like this, photoconduction PG is as separator or distributor.As shown, this point can increase the external frame PF that distributes and go up selected area, has the good especially light yield of external frame top end that is positioned at distribution, be shown as the non-imaging 3 of framework, and right side shown in the figure has not by the demonstration output light K of deflection with the real surplus in the front by passive framework.In this embodiment, as directed, produce the light of high brightness from the external frame PF of 2 distribution being appointed as the non-imaging 3 of framework.

Here anything that comprises simple block passive diffuser frame P can be used.Figure 14 illustrates the view similar to Figure 13, utilize the external frame of simple block diffuser as photoconduction and distribution, and Figure 15 illustrates similar embodiment, is not having under the situation of diffuser material, utilizes the external frame of simple transparent block as photoconduction and distribution.Equally, the use of diffuser material can be used in the limited method, for example in Figure 16 of the passive diffuser frame that Figure 13 is shown, wherein under the condition that does not have the front diffuser, forms transparent light guide and upwards penetrates to allow surround lighting.As what can see, internal reflection output light KX upwards transmits, by photoconduction PG outwards to become the non-imaging 3 of the framework that is sent to external environment condition.

Among the embodiment in front, the benchmark area FA that sacrifices described display D is used to provide the light that is input to passive diffuser frame P.This point may be unsatisfactory for original display imaging 1 for some of unallowed minimizing in the available picture size.The losing of scene details may be offended or make angry or be reduced interest for this ambient light system.Another embodiment of the present invention allows to observe edge pixel (because refraction effect may spatially be moved), allows simultaneously to show that output light K is injected among the photoconduction PG of passive diffuser frame P.

With reference now to Figure 17 and 18,, show the cross section close up view that is equipped with the display top of Amici prism according to embodiments of the invention, this Amici prism is equipped with passive diffuser frame.In each figure, form as shown photoconduction PG with critical angle place that allows critical surfaces CS to be present in to be used for total internal reflection or near.In Figure 18, for example, the right-hand front of going up the external frame PF that distributes that is presented at figure is tilted to form critical surfaces CS, and the normal vector of this critical surfaces CS approximately departs from 45 degree from the common output light outward direction D (K) that sees easily.Because the critical angle of the internal reflection of most of particle typically is approximately 42 degree, this provides a kind of chance that photolysis is entered into photoconduction PG, because selected geometry, as directed, almost half light that enters will be above critical angle to become internal reflection output light KX, as directedly become (although strict the saying of the non-imaging 3 of framework, if diffusion Be Controlled, can keep image for projection upwards as shown)-and second half light that enters photoconduction PG will not be changed direction, but launch forward and become the output light KT that is transmitted, and become framework image light 2 as shown.Therefore, spectators will receive or distinguish the primary characteristic of original displayed image among the reference area FA, yet, distributing for environment simultaneously, light can be used to from the upwards emission of external frame PF that distributes.See original display image under the brightness that therefore bright or transparent passive diffuser frame P allows reducing in whole viewing area, this point does not pay particular attention to owing to human visual system's compensation characteristic itself.

Also show additional feature, promptly use front surface reflector or reflecting surface T with the reverberation of reflection photoconduction PG inside to become environment separation light (illustrate, separate).This luminous energy illuminates the rear wall shown in Fig. 7.

By explanation, the performance of the outward appearance of present embodiment is illustrated among Figure 19, Figure 19 shows the display of embodiment of Figure 18 and the front schematic view that passive framework upper divides, and the continuity of the image by passive diffuser frame, and allows to show that output light changes direction to become surround lighting.The part of the sun that illustrates and be presented at the aircraft that shows on the original image can to cross critical surfaces CS in sight by the external frame PF that distributes.This image of seeing by the external frame PF that distributes is shown as framework image light 2; The non-imaging 3 of framework that produces from the external frame PF that distributes also is shown as before.For purpose attractive in appearance, shown front surface reflector or reflecting surface T are the twice of chromium or other metal trim on function, and it exercises the function of optics, promptly helps surround lighting to penetrate outside the rear of passive diffuser frame P to provide rear side to separate (not shown).

Usually, instruction given here also can be applicable to many aspects.Geometry for the Amici prism of the external frame PF that distributes can comprise single plane, whole framework border, as shown in FIG.; Interchangeable, framework comprises four planes, and each is corresponding to the every side that shows the benchmark border, that is, and and top, bottom, left side and right side.Interchangeable, may there be regional prism or little prism, even the prism of Pixel Dimensions is to obtain to go up on a small scale identical influence.

Usually, the form of passive diffuser frame P can with the expection the same variation of light varying effect.The distribution of surround lighting may be simple or complicated.Simple diffuser block or the like can be used for the distributing light of approximate bounds pixel U among the benchmark area FA, this light can be distributed to the general color of whole passive framework front (and/or side) to give to go out from the framework elm among the external frame PF of distribution isogonism then.On the other hand, can obtain the zone by the external frame PF that specifically forms photoconduction PG and distribution or special effects is used for providing preferred optical channel or break-in in selected zone.For example,, may there be periodic passage, the mark of surround lighting for example is provided, for example light is sent to the zone of expection, or illuminate specific feature, for example red ball, blue line or the like in specific direction or for specific purpose.Can obtain specific side or edge effect to framework self.

Can see an example with reference to the Figure 20 that shows the embodiment of Figure 18, among Figure 20 photoconduction PG comprise for further distributional environment light to ad-hoc location or be in two the photoconductive tube P1 and the P2 of specific purpose, not shown.The surround lighting M that produces from these two photoconductive tubes that illustrates is for other local use, and the base plate of light distributor (not shown) for example being installed or being produced the ceiling flashing light unit (not shown) of special-effect can be by optical pumping in other optical texture.For the purpose that environment distributes, in order to amplify, photoconductive tube also can be used for transmitting light.

Figure 18-20 shows the interchangeable embodiment of Amici prism embodiment.Figure 21 shows function and the identical the present invention shown in 18, utilizes partial reflection surface T2 to substitute the internal reflection of critical surfaces CS.As before, part light, i.e. internal reflection output light KX distribute for environment and emission upwards reflection is as the non-imaging 3 of framework, and other light is transmitted and become the output light KT that is transmitted.As directed, the external frame PF major part of distribution can be a hollow, and has optical channel shown in Figure 180.It can be favourable utilizing local reflex surface T2, because there is not the refraction misalignment effects on the image, just as the internal reflection with the refraction shown in Figure 18 is identified by critical surfaces CS; Yet, utilize the local reflex surface to have the shortcoming of introducing some light losses at reflecting surface, and the internal reflection at the critical surfaces CS place 100% of Figure 18 is absolute.In addition, as directed, front surface reflector T is used to increase the separation backward of surround lighting on the top of whole display D.As the alternative embodiment of local reflex surface T2, can utilize the reflector of selection on a small scale, it directly reflects and changes all and shows directions of light, at light by the passage between the reflector of these selections to become the framework imaging.

One of obtainable function of the present invention is by obtaining from original displayed image light 1, rather than the product of the passive framework of in esse colourity.This point is carried out under the situation without any active intervention by passive framework, and and do not rely on heat or existing light source, LED for example, even when primary colours are combined, its colourity as discussed previously is difficult to Be Controlled.Light by the external frame PF break-in that distributes can be non-imaging and mixed, allows the combination of primary lights or other color of light.Two kinds of color A and B that this point allows to come from two different scene areas on the display can form not shown chrominance C on original image, but are pleasant to eyes, obtain from the content of original image as it.This point can be found out with reference to figure 22-31.

With reference to Figure 22 and 23, provided the embodiment of Figure 18 and 19, utilize the identical viewpoint shown, and the blend of colors of color composograph is to produce surround lighting colourity on the expression video display, this colourity is the result of the output combination of a plurality of display pixels in the single viewing area.Figure 22 illustrates the similarly positive top with Figure 19.In this example, it is red being illustrated in the discernible aircraft in passive diffuser device framework P back, and produces shiny red framework imaging 2R, and as directed, the top of some trees produces the green framework imaging 2G of high brightness.In Figure 23, the corresponding output light K that shows is respectively as two kinds of different light source KR and KG, and the promptly red and green output light that shows is illustrated.The part of this colourama KR and KG is not departed from basically, produce framework imaging 2, and some are by internal reflection and upwards break-in, in the end face place combination of the external frame PF that distributes, and mix (MIX) as shown in the figure to produce the non-imaging 3Y of as directed metameric yellow framework.Therefore, when the scene element is a different and independent redness and when green, the surround lighting that passive framework produces can be yellow, so that interested stagewise to be provided.This point is along with the use of diffuser especially is improved, and as shown in figure 24, Figure 24 is similar with Figure 13 on function.Exercising this function in light illumination mode, to need the redness in this example and the light source of green light be bright, for example when utilizing inner nail and photoconductive tube light belt to be gone into and when putting on the fraction of external frame PF of distribution.The process of this basic principle figure is illustrated among Figure 25, and wherein azarin light and green glow are brought into together putting on the external frame PF that carries out the extra distribution that mixes by photoconduction PG, thus the yellow surround lighting Y shown in causing.

Under similar circumstances, yet the flow of ruddiness and green glow is not very strong, and passive diffuser frame P will be with the target pattern functionating, shown in Figure 26 and 27.There, extra blend of colors produces brown light (brown) among the external frame PF of Fen Peiing as shown, as mentioned above, utilizes the LED in for example near scope of bright active light source, and this point is not possible usually.

In seeking the process of utilizing human eyes characteristic, can obtain color modulation by the present invention.Provide for the luminosity function of the detection sensitivity of different vision wavelength function and change as intensity level.

The noctovision or the night vision that depend on rod are tended to more responsive for blue light or green light.Utilize the photopic vision of retinal cones more to be applicable to the wavelength that detects than long, for example red and yellow.In the home theater environment of dark, change on some degree by modulation or change the color that sends video user to being cancelled as these of the relative luminosity of the different colours of the function of intensity level.This point utilizes the color subtraction step to realize.

Therefore, Figure 28-31 show to Figure 24-27 in similar paired figure for two illustrative embodiment of the present invention, wherein passive diffuser frame P comprises transmission absorption device TA (Figure 28) respectively, and reflection-absorption device (Figure 30), have the corresponding light that schematically shows in Figure 29 and 31 respectively and reduce and the increase process.Especially, in Figure 28, the inner surface of the external frame PF of distribution and transmission absorption device TA are in alignment, and the function of this transmission absorption device is from being absorbed the wavelength of selecting the light of propagating as the non-imaging 3 of framework.This transmission absorption device TA can be a metallic film, for example gold or aniline dyes; Or in passive diffuser frame P, can exercise optical function and stable any other absorber.Metallic film for example gold thin film allows green light and blue light by wherein, absorbs the light of longer wavelength, and this point can be supposed to have the visual angle of high brightness levels.Here schematically illustrated another example, wherein after passing through transmission absorption device TA, rgb light has some absorbed green light, thereby has produced the green glow g of low-light level.

Substitute transmission absorption device TA, can use the reflection-absorption device.In a similar fashion, Figure 30 and 31 illustrates the side being arranged in photoconduction PG or the reflection-absorption device RA of a plurality of sides, and is therefore as directed, distribute for environment, reverberation from its upwards by or pass through to other place of the external frame PF of distribution.

Utilize other embodiments of the invention, further color transformed is possible.With reference to Figure 32 and 33, another embodiment of the present invention is shown, it is color transformed that wherein passive diffuser frame utilizes the execution of luminescence generated by light device.As shown in example, photoconduction PG and luminescence generated by light device PE are in line, and this luminescence generated by light device is used for from the demonstration output light K absorption of introducing or through excited target, and stand to be transmitted into the wavelength of expectation again.By this excitation and the emission again of luminescence generated by light device, for example fluorescent pigment can allow to be presented on non-existent new color in the raw video image, perhaps also has not in the colour gamut of the operation of display itself or the new color in the color gamut.In corresponding schematically process shown in Figure 33, new layer or the functional steps of luminescence generated by light device PE is shown, it has orange-colored light, the orange illustrative example of searcher for example, for this example can with fluorescent pigment be known (referring to ref[2]).The example that provides relates to fluorescent color, and is opposite with common phenomenon of fluorescence and relevant phenomenon, is devoted to this figure for this reason.Any photic mixture, material or material can be used for luminescence generated by light device PE, as long as it shows that for response output light K has activation or excitation energy.
