The frame may include a light modulator, or an angular photometric or angular chromatic element, to change the characteristics (intensity, color) of the ambient light as a function of the viewing angle, or a luminous emitter for new colors outside the full range of display colors. It may include. The frame can split light between an observer and a frame input and can derive an added video signal to drive a selected display pixel to raise the output of display light into the frame.

Description

ACTIVE FRAME SYSTEM FOR AMBIENT LIGHTING USING A VIDEO DISPLAY AS A SIGNAL SOURCE}

The present invention relates to the generation of video displays and ambient lighting effects derived therefrom. More specifically, the present invention controls and generates lighting effects for distribution to the periphery, including spatial and colorimetric conversion of display light to produce effects that cannot be provided by conventional video display units or light-transmitting elements. To an active diffuser frame system using video display light and / or display video signal as an optical, signal, or content source.

Technicians have long extended the realistic picture and projection area, including wider video color gamut, resolution, and picture aspect ratio, for example, for high definition (H (D)) digital TV and video systems, with realistic three-dimensional effects Research continues to expand the sensory experience gained by consuming video content by adjusting the sound and improving the quality of the video image. Furthermore, film, TV, and video producers can also use viewers to visually and auditory means, for example, by the use of color, scene cuts, viewing angles, surrounding landscapes, and computer-aided graphical representations. Try to influence your senses. This will also include stage lighting. Lighting effects, for example, are typically written in script, ie synchronized with video or acting scenes, and reproduced with the aid of a machine or computer program for the appropriate scene script with the desired structure. Automatic adaptation of lighting is usually not possible for fast changes in any scenes, especially unplanned or scripted scenes.

Philips (Netherlands) and other companies have disclosed means for changing ambient or ambient lighting to improve the quality of video content for typical home or business applications, but this is typically far from video displays, and In many applications, the use of a separate light source is irrelevant to any improved script or encoding of some kind of desired lighting effect. Ambient light added to a video display or television is known to reduce observer fatigue and improve the realism and depth of the experience. However, the generation of ambient light in the immediate vicinity of the display output has proved to be problematic in practice.

The present invention uses an active frame or active diffuser frame system to use the captured video display light or the video display signal from the video display unit itself to produce light aura or effects. The video display unit can use any technology or platform, such as CRT (cathode ray tube), LCD (liquid crystal display), PDP (plasma display panel), FED (field emission display) or other technology. In many embodiments, this may even apply to any transmission medium for the delivery of video or visual information, such as found in windows of a building. For clarity of discussion, video displays will be used herein for illustrative purposes.

Sensory experience is naturally a function of aspects of human vision, which uses a number of complex sensory and neurological devices to create a sense of color and light effects. Humans can probably identify 10 million distinct colors. In the human eye, for color-receptive or photoelectric vision, there are approximately two million sensory bodies, called cones, which are very much superimposed, with peaked absorption distributions at 445, 535 and 565 nm light wavelengths. There are three sets. These three cone cell types form what are called tristimulus systems and are called B (blue), G (green), and R (red) for historical reasons; Peaks do not necessarily correspond to any primary colors used, for example, in displays that typically use RGB phosphors. There is also an interaction for dark adaptation, called so-called night vision, called rod. Human eyes typically have 120 million rod cells, which affect the video experience, especially in low light conditions such as those found in home theaters.

Color video is built on the principles of human vision, and how the well-known three-primary and complementary channel theory of human vision affects the eye to see the effect of high fidelity on the desired color or intended image. It is included in our understanding. In most color models and color spaces, three-dimensional or magnetic fields are used to describe the human visual experience.

Color video is absolutely dependent on metamerism, which allows the generation of color perception using a small number of reference stimuli, rather than the actual light of the desired color and characteristic. In this way, the full range of colors is reproduced in the human mind using a limited number of reference stimuli, such as the well-known RGB (red, green, blue) tristimulus used in video playback worldwide. For example, it is well known that almost all video displays show yellow scene light by generating approximately the same amount of red and green light in each pixel, i. The pixels are small in relation to the corresponding solid angle and the eye is deceived to perceive yellow; The eye does not recognize the green or red that is actually being broadcast.

Many color models and color specific schemes exist, including the well-known Commission Internationale de l'Eclairage (CIE) color coordinate system used to describe and specify colors for video playback. The present disclosure does not exclude the use of displays or color spaces that use bistimulus or quadrapole systems, or systems that produce multiple reference stimuli. Any number of color models can be employed using the present invention, including applications for complementary color spaces, such as CIE L * U * V * (CIELUV) or CIE L * a * b (CIELAB). The CIE was established in 1931 as the basis for all color management and reproduction, and the result is a chromaticity diagram using three coordinates x, y and z. At maximum luminance, the drawing of this three-dimensional system is commonly used to describe color in terms of x and y, and it is believed that this drawing, called the 1931 x, y chromaticity diagram, can describe any color perceived by humans. . This is the opposite of color reproduction, in which conditional lighting is used to deceive the eye and the brain. In order to reproduce colors using three primary colors or phosphors, many color models or spaces are used today, such as ISO RGB, Adobe RGB, NTSC, RGB and the like.

However, it is important to note that the range of all possible colors represented in video systems using these tristimulus systems is limited. NTSC (National Television Standards Committee) RGB systems have a relatively wide range of colors available, but they can only reproduce half of all colors perceived by humans. Many blue and purple, cyan, and orange / red colors do not render properly using the available range of traditional video systems.

Furthermore, human perceptual systems are endowed with the nature of the compensation and discrimination whose understanding is necessary to design any video system. For humans, color can occur in three or four appearance modes, including object mode and ore mode.

In the object mode, the light stimulus is perceived as light reflected from the object illuminated by the light source. In the body mode, the light stimulus is seen as a source of light. The hull mode includes stimuli in the composite field that are much brighter than other stimuli. It does not include a stimulus known as a light source, such as a video display, whose brightness, or brightness, is equal to or lower than the overall brightness of the scene or visual field so that the stimulus can appear in the target mode.

Specifically, there are many colors that appear only in the target mode, such as brown, tan, maroon, gray, and beige fresh tones. For example, there is no such thing as a brown light source, such as brown traffic light.

For this reason, supplemental means for video systems that attempt to add a target color cannot use a direct light source. The combination of bright red and green LEDs in any near range cannot reproduce brown or tan at all, which greatly limits the selection. By direct observation of a bright light source, only the spectral colors of the rainbow, of varying intensity and saturation, can be reproduced.

The active diffuser frame system of the present invention relies solely on the video input, without script or additional communication for the required ambient light coding, and can use multiple inputs from the video to improve the realism and fidelity of the video image.

Conventional systems that attempt to introduce light into the ambient space operate separate entertainment control signals required by the lighting entertainment system disclosed in US Pat. No. 6,166,496 to Lys et al., Or ambient lighting disclosed in US 2003/0057884 such as dowling. A separate channel of information is often required for system operation, such as computer code or computer application content needed to make the application work. Almost no video broadcast system places ambient lighting codes or commands in any analog waveform space, such as the vertical blanking intervals in an NTSC broadcast system, and virtually any digital video system (e.g. DVD format, MPEG4, etc.) Do not place the ambient lighting code within any subcode, such as a DVD subcode or a composite digital video subspace.

Another drawback of many conventional ambient lighting systems is that the light source used cannot display video information in the object mode, so that a large area in the human color space cannot be generated by the human color space.

Another disadvantage is that the current description of the ambient light located in proximity to the video transmission element or display tragically loses the opportunity to exploit the known characteristics of the human visual system. One possible reason to avoid ambient lighting that closely matches in terms of close physical proximity to video display units using active light sources is that the generated image is often required, inadequate, and not dense.

Oftentimes, conventional light sources for generating ambient lighting and methods of driving them are a poor combination for the quality and nuance of video displays. In other cases, the derivation of a virtual image space of the kind that essentially creates another complementary video display for generating ambient lighting-relies on what is found in US Pat. No. 6,661,297 to Akashi et al. In 6,661,297, although it is proposed that the frame around the display can be used in pseudo light emission or target mode, separately induced lighting control data is required, and also the creation of a virtual video space embedded in separately recorded lighting control data. Using an inexpensive system that does not require or correspond to a complementary video display, its available color space is comparable to--or beyond--the display itself to provide satisfactory and practical output. No teaching about doing It is not empty.

It therefore essentially does not undertake the creation of a virtual image space producing a second display to be used as an optical frame and does not require separately derived lighting control data, and rather only relies on data directly available from the video display unit. It is advantageous. It is also advantageous to exceed the full range of colors available for traditional light sources and to extend the full range of colors reproduced by a typical tristimulus video display system. It also provides video users with an active diffuser frame system that makes good use of the compensatory effects, sensitivity, and other specificities of human vision best used within the frame surrounding the display, or provides ambient light in close proximity to the video display. By modulating or changing the transmitted color, it is desirable to exploit the characteristics of the human eye, such as a change in the relative luminosity of the different colors as a function of light level. It is also desirable to make these systems backwards compatible with existing broadcast and production standards such as NTSC, SECAM, PAL, and MPEG4.

With respect to the light capture discussed below, prior art frames surrounding the video screen do not function in the way that the present invention does to capture, redirect, and broadcast light as taught herein. . In contrast to many prior art designs, the present invention is not related to metering inside a display, such as a traditional CRT. The invention selectively captures light only from the front display surface, for example RMBowie, US Pat. No. 2,837,734, Surround-Lighting Structure, shows that CRT metering from a transparent glass band 22 Captured by the plate transparent member 30.

The present invention provides a high degree of freedom and high realism for creating desired (and new) saturation and effects without creating another virtual image space, such as separately derived and recorded lighting control data to be used to drive other supplemental displays. An apparatus and method for an active diffuser frame system for a video display unit.

FIELD OF THE INVENTION The present invention relates to an apparatus and method for an active diffuser frame system for a video display unit for broadcasting caravan light into an ambient space, wherein the system is directed to directing output light from itself to produce ambient light. Any of a plurality of controllable light sources, having the same size, location and optionally formed, is used. This light source includes many kinds of lighting elements or lighting arrays, which are formed and configured to allow control of ambient light using at least an active diffuser frame unit derived from the video display unit itself in order to increase fidelity and realism. Three active frame inputs, namely a passive light input of display output light from the [a] video display unit; [b] passive sensing of display output light from the video display unit using the display light sensor; And [c] at least a portion of the active video signal driving the video display unit may be used together in each or in any combination. Display output light from the display may be mixed with light from the controllable light source. Output light generated through or within the active diffuser frame is broadcast to the surrounding space using a distributed outer frame or frame light modulator to disperse the output light into the surrounding space in the observer mode.

The present invention allows the original original display light from the video display to be used in an active frame system, for example to illuminate or to help illuminate a distributed outer frame. In one embodiment, active interference to the display itself is achieved by using the latter two active frame inputs to drive selected output pixels of the video display using a processor to generate a starting area video signal provided to the video display unit. There is a possibility to increase this contribution from the display. This drives the reference output pixel in the video display unit that is used directly by the frame and possibly resides in the starting area to produce modified display light, possibly mixed with light from the controllable light source.

The present invention relates to an indoor condition sensor that senses an ambient condition in a surrounding space around a video display unit, such as, for example, an indoor light sensor, an indoor acoustic sensor, and a frame contact sensor, to allow for sensing an indoor condition, and for example, a gorgeous Or a user preference input to cleverly use a specific characteristic of human vision and toggle or selection between active frame output modes, such as suppressed.

It may include. This makes it possible to adjust the ambient light generated by the active frame to account for recent scene light, such as bright stimuli, to make the ambient light output more plausible and less colorful.

The light source may include a light emitting diode (LEd), an electroluminescent element, an incandescent lamp, an ion discharge lamp, a laser, a field emission display (FED), a liquid crystal display (LCD), a frame light modulator, and a photoluminescent emitter, This can be combined with display output light obtained using the light guide.

The light guide splits a portion of the display output light from the video display unit within the active frame so as to be redirected for use by the active frame by reflection from the surface and other display light toward the viewer as image light. By allowing it to pass substantially outside, the observer can be configured to still see the entire image area on the display.

The active diffuser frame system may include a photoluminescent emitter for modifying the spectrum of the light source to color-convert ambient light emitted from at least a portion of the active diffuser frame system. This photoluminescent emitter may be selected such that the generated ambient light includes at least one new color outside of the full range of display output light colors inherently generated by the video display unit not assisted by the active diffuser frame system. Can be.

Other embodiments provide that the active frame changes characteristics as a function of the goniophotometric, ie, the viewing angle (N, 2) of the active diffuser frame system, or more specifically, the goniochromatic, ie active It includes the use of an angular photometric element that allows to emit ambient light, changing color as a function of the viewing angle of the diffuser frame system. Angular photometric elements include: metal pieces, glass pieces, plastic pieces, particulate matter, oils, fish scale essences, guanine flakes, 2-aminohypoxanthine, crushed mica, crushed glass, crushed plastics, pearl material, semi-glossy, And materials such as working bronze.

It may simply be inserted between and in optical communication with each other. An active diffuser frame, such as taking the form of a prism block, can incorporate both the function of a light guide and a distributed outer frame . They do not need to be separate components. In its most general form, the light guide is, in this specification and the appended claims, whether optical or material objects, or even vacuum or atmospheric spaces, frame light modulators, dispersive outer frames, photoluminescent emitters or their It is defined as anything bounded by other components in the frame and the light sources according to the invention, such as any combination.

Referring now to FIG. 1, an exemplary front surface diagram of rectangular video display D is shown as having a total active or light generating front surface area DA such as the product of height h and width w as shown. . The display D may include a plurality of pixels, ie, pixels U, that generate display output light K, as shown. The peripheral region, shown as FA, is used as the starting point region dedicated to the generation and dispersion of the ambient light using one embodiment of the present invention for illustrative purposes.

Referring now to FIG. 2, a front schematic view of a conventional RGB video pixel in the display of FIG. 1 is shown for illustrative purposes. As in most displays, the display output light K from the subpixels or components of the pixel U is multi-directional, so the video display D can be conveniently viewed from a wide angle range. This multi-directionality of the output will be used for the advantage as found in the embodiment depicted in FIG. 20.

Referring now to FIGS. 3 and 4, schematic side cross-sectional views of a cathode ray tube display and a flat panel display are shown, respectively. In each figure, the display D is oriented such that its display output light K can be emitted in multiple directions to the right on the page as shown, in a general output light outward direction D (K) as shown. do. Each display D has an active diffuser frame A according to the invention in optical communication with the display, which captures light from the starting area FA as shown in the surface view of FIG. 1. Is mounted. For clarity, only the active portion of the display is shown here, so the total display height h shown is active. There is an observer or observer Q at some distance from the general direction D (K), which is schematically illustrated as a cross section of the eye.

Referring now to FIG. 5, an enlarged view of the upper portion of the schematic cross-sectional view of FIG. 4 is shown. The upper part of the side of the display D is shown optically coupled to the active diffuser frame A. FIG. The active diffuser frame A may be mechanically mounted on the display D and may also comprise a flange and slip-on shape for this purpose or be suspended only in optical communication with the display D. Can be. The active diffuser frame (A) can be made of a number of commonly available transparent or translucent materials, also known as transparent plastics, such as, for example, Lexan®, Lucite®, and many other polymeric resins such as PET and ABS resins, also known It can be formed using manufacturing techniques. Any known stable light transmitting material with the required mechanical and optical properties can be used. As noted below, as noted below, the portion of the active diffuser frame A that allows the display output light K to enter and optically couple to the active diffuser frame A is a light guide. Called; The portion used to rebroadcast this light to be ambient light is called a distributed outer frame (shown as AF). The distributed outer frame AF may comprise a distributed frame outer surface AS as shown. The display output light K can be redirected and shown as redirected light J, resulting in ambient light M as shown. Ambient light M is opposite to the normal output light outward direction D (K), such as toward the observer Q as shown, and also away from the observer Q (shown as spill). Can be emitted in any direction, such as in a direction. In this example, the ambient light leaks onto the back wall N in the ambient space behind the display D, becoming ambient reflected light MR, which is probably sent in the normal output light outward direction D (K). It is shown that observer Q will be able to see the original display image light. The active diffuser frame A, and in particular the dispersion frame outer surface AS, may comprise a frosted or glazed surface AS, depending on the desired visual effect; Glass or plastic, including rib structures, such as by using metal or other internal interceptors; Alternatively, it is possible to implement various diffuser effects for generating light mixing as well as translucent or other phenomena such as hole structures. The simple active diffuser frame A is shown here for the sake of clarity. As shown below, using the original display light is not necessary for the active diffuser frame (A).

Referring now to FIGS. 6 and 7, one general effect is illustrated by way of example. 6 shows a schematic surface perspective view of the upper right portion of the display D, equipped with a generalized block active diffuser system, according to one embodiment of the invention. As shown in FIG. 6, the active diffuser frame A will be peripheral in nature, and-although not necessarily-use light from the starting area FA on the periphery of the display or on any desired area. It is not required, but is expected. Only part of the frame is shown for clarity. Note how the ambient light M, including the sides and top of the display D, can be emitted in a direction in the peripheral space Z as opposed to the normal output light outward direction D (K). The observer Q receives not only the original display image light 1 as shown from the non-origin region of the display, but also the ambient light M coming from the active diffuser frame A as shown. That is not shown here in FIG. 5, active frame control inside the active diffuser frame A, which can be controlled in part based on display output light K or other active frame input as shown below. Possible light source LS.

A general effect is illustrated by way of example in FIG. 7, where an active diffuser frame (capturing some sun and approximate topographical form is shown) from the starting point area FA as shown in FIG. A front schematic view of the display D using A) is shown. This light is captured using a light guide (not shown) to be used by the active diffuser frame system to send light from the distributed outer frame AF (shown) to the surrounding space as ambient light M. Dispersion outer frame, shown here as having a height H and a width W greater than the height h and width w of the surface area DA of the active display D as shown in FIG. 1. There is no restriction on the type of AF.

Referring now to FIGS. 8, 9, and 10, a non-intercept active diffuser frame system embodiment is shown in a similar form to the figures of FIGS. 5, 6, and 7. FIG. 8 shows an enlarged view for a non-intercept embodiment similar to that of FIG. 5, but without the active frame intercepting light from the video display unit, generating its own light. The active diffuser frame A has its own light source (as shown) which now generates light as shown, together with a representative schematic light ray LJ which provides radiant energy for producing ambient light M as shown. LS). The light source LS may include any of the following: [1] LED (light emitting diode), [2] electroluminescent element, [3] incandescent lamp, [4] ion discharge lamp, [5] laser, [6] Any number of known controllable light sources, including an LCD (liquid crystal display), [7] frame light modulator, [8] photoluminescent emitter, or an array functioning like a display.

FIG. 9 is a view similar to that of FIG. 6, but shows a schematic surface view for the non-intercept embodiment of FIG. 8. Note that the active diffuser frame A does not blur or intercept the original display image light 1. FIG. 10 shows a similar schematic front view of a display D using an active diffuser frame A, where, as shown, the active diffuser frame A does not directly intercept or use the original display light. Do not.

The dispersive outer frame AF may comprise a diffuser for changing the characteristics of the ambient light produced, as schematically illustrated herein. Long-life organic mixtures, which are known to those skilled in the art for their production and preparation; Gels; And small suspended particles inside the diffuser object, including a sol; Rigid foam; Any number of known diffuse or scattering materials or phenomena, including preparation using scattered plastics or resins, such as colloids, emulsions, or small spheres of 1-5: m or less, such as less than 1: m This can be used. Scattering phenomena can be designed to include Rayleigh scattering over visible wavelengths, such as for generating blue to enhance the blue of ambient light. The generated color may be defined locally, such as having a blue tint or a regional tint overall in a particular area, such as a blue light-generating top portion.

Referring now to FIGS. 11 and 12, whereby the active diffuser frame A is functionally angular photometric, and also active display of passive detection of display output light from the video display unit using the display light sensor or sensors. Another embodiment of the invention for use as an input is shown. FIG. 11 shows a generalized schematic cross-sectional view of the upper part of the active diffuser frame system according to the invention, in a manner similar to FIG. 5, wherein as shown, the display output light K from the display D is A light guide (not explicitly shown for clarity) is used to transport the display light sensor DS. The display light sensor DS may include one single sensor to control the light source LS as shown, or may be used as an electrical or other signal to be used by a processor not shown. A plurality of sensors, such as a photovoltaic cell for converting K), or a sensor block using any number of known photo-sensing converting elements, such as charge coupled devices. The display light sensor DS is wrapped inside the active diffuser frame A using a separator S as shown to prevent the passage of light and / or heat from the light source LS to the display light sensor DS. Lost The light source LS generates frame light, which passes through the light guide LG which is now clearly shown as the active frame light beam LJ, as shown. The light guide LG guides the light from the light source LS to the dispersive outer frame AF, while the ambient light, now shown as frame non-image light 3, enters the surrounding space around the display D. . Note that the frame non-image light 3 can pass back to the left on the drawing to leak backwards, as also shown in FIG. 5.

The active diffuser frame A, and in particular here, for illustrative purposes-a distributed outer frame AF-is formed inside the light guide LG and / or the distributed outer frame AF, as shown here. It is shown mounted with a kind of angular photometric element, shown here as a cylindrical prism or lens that can be integrated, integrated or inserted therein. This enables the special effect that the characteristics of the generated frame non-image light 3 change as a function of the viewer's position. 11 illustrates an angular photometric effect that provides different light intensities and properties for frame non-image angular photometric light 4 as a function of viewing angle. Light from the light source LS enters the cylindrical prism, ie the angular photometric element AN, through the light guide LG as shown. In the sample beam shown, the light-depending on the entry point on the cylindrical surface of the cylindrical prism used as shown-and the observer or human observer Q at the intermediate position point as shown is Non-isotropically out of the angle photometric element (AN) in such a way that it perceives different light intensities from the angle photometric element (AN) as compared to the vertically lower observer (-Q) or higher observer (+ Q). Reorient. This effect may, for example, allow a user or observer to see this effect when he is in a chair, or the position of the user to see different light perceived light levels or intensities from an angular photometric element (AN). You can allow a bit to adjust. This allows to change the intensity of the ambient light generated according to personal preferences, based on small changes in viewing position. Other optical shapes and shapes can be used, including prisms or shapes having square, triangular or irregular shapes, and they can also be placed or integrated on the dispersive outer frame AF as desired. Rather than isotropic output, the effect obtained here can vary infinitely in the bands of interesting light shining on the surrounding wall, object, and surfaces, for example located around the display D, so that the scene elements, colors, and intensity on the video display unit change. When you do, you can create a kind of light show in a dark room. The number and type of angular photometric elements that can be used are almost unlimited, including plastic pieces, glass pieces, and optical effects produced by gold or weakly destructive manufacturing techniques.

The appearance of the active diffuser frame A and the display D is shown in FIG. 12, where a front schematic similar to that of FIG. 7 is shown for the angular photometric active diffuser frame system of FIG. 11. Display D emits the original display image light 1 as shown. Using a diffuser core or shaped diffused outer frame AF, the ambient light M takes the form of frame non-image light 3 as shown, and also an angular photometric element shown in cross section in FIG. It also takes the form of a frame non-image angle photometric light 4 emerging from (AN).

Referring now to FIGS. 13 and 14, a non-intercept active diffuser frame system according to the present invention, which uses an active video signal supplied to a video display unit to control a light source LS inside an active diffuser frame A. FIG. A generalized schematic cross section of the upper part is shown. In FIG. 13, the video display signal RF includes its coaxial line, optical fiber, wireless link, or source of any other signal or bitstream that provides video information and any relevant data to the display D, Any known method, including known inductive sensing or pick-up of signals using consumer-provided adapters, including indiscriminate taps of signal lines or transmission lines, or some integration method where signals are obtained from within the display D Way, it is schematically shown as being obtained from the display D. This may include infrared, Bluetooth, or pulse width modulated communication from the display to the processor CPU as shown. Known compression techniques can be used for this communication. The data tapped for the video display signal (RF) may comprise an analog signal, such as an NTSC, PAL or SECAM waveform, and may also be digitized, including source coding and any subcode or auxiliary data, or metadata. It can consist of information. The video display signal RF then uses principles known in the art of video and television engineering by the processor CPU, shown here as integrated or appended to the active diffuser frame A as shown. Is used. In the alternative, the processor CPU may be integrated within the display D or may be positioned independently of either the active diffuser frame A or the display D. FIG. As before, light from light source LS passes through light guide LG and exits to dispersive outer frame AF, producing frame non-image light 3.

In Fig. 14, another embodiment is shown in which the active diffuser frame system utilizes remote sensing such as electromagnetic couplers EC1 and EC2 for the active frame input of the video display signal RF delivered to the video display unit. In this embodiment, the video display signal RF, a portion thereof, or a signal derived from the video display signal RF drives the electromagnetic coupler EC1 in such a manner as to encode desired information from the video display signal RF. To be used directly or indirectly, using techniques known in the electronics and electrical arts. If necessary, for example, sampling only a subset of the pixels in the display, averaging technique, or reduction of data loaded on any driver (not shown) needed to feed the electromagnetic coupler EC1 may be allowed. As with any other compression sampling that is present, there may be some processing done to simplify the video signal. In the analog manner, the processor CPU may use a signal inductively or electromagnetically received by the electromagnetic coupler EC2, which is in electromagnetic communication with the electromagnetic coupler EC1. This allows for easy portability of the active diffuser frame A, especially for flat panel (non-CRT) displays. Electromagnetic coupler (EC2) may take the form of an antenna or may be obvious, such as those commonly available and known in the art, using IREDs (Infrared Emitting Diodes) or similar emitters for encoding and transmitting signal information. It may be an optical device. Any number of configurations can be used. For example, electromagnetic coupler EC1 can be part of, attached to, or coupled to display D, while electromagnetic coupler EC2 can be part of active diffuser frame A, thereby providing portability and exchangeability. Allowed.

Referring now to FIG. 15, the active diffuser frame A is shown according to a different embodiment than that shown in FIG. 13, where output light from light source LS is modulated by frame light modulator AM. do. As shown, the frame light modulator AM is now part of the distributed outer frame AF, and is also inserted in between the light source LS and the distributed outer frame surface AS, so that it emerges from the light source LS. Properties, such as intensity of light, hue or saturation, may be changed prior to ambient dispersion, as shown, to be referred to herein as modulated ambient light 3M. This may allow for any number of lighting effects whose execution is determined by content derived from an active frame input, such as a video display signal RF. Frame light modulator (AM) is a single element, such as found in a single element, or a flat array of such elements, such as found in LCDs (liquid crystal displays), varying in transmission or throughput as a function of time or position, Or it may include one composite device that allows light to pass through itself but is also an active light source such as an FED (electroluminescent display) or a PDP (plasma display panel).

As another example, referring now to FIG. 16, a view similar to that of FIG. 15 is shown, but this is for another embodiment that uses a partially intercepted configuration, whereby as done in the embodiment of FIG. 11, Some display output light K is also allowed to enter the light guide LG. In this embodiment, both the display output light K and the output light from the light source LS pass through the light guide LG and go out through the distributed outer frame AF to the surrounding space.

Using a frame light modulator AM, the scene can be projected onto a distributed outer frame AF that complements the content from the display D in a satisfactory manner. The derivation of the control signal for generating such content starts with an active frame input derived from the video display unit D, and does not need to come from a script, subcode, or dedicated data in the video display signal RF.

The light redirected by the dispersive outer frame AF may be non-image light and may be mixed light, allowing a combination of primary and other colors. This allows for a blend as shown in Figure 24, so that two colors (A and B) from two distinct scene areas on the display are not shown in the original image when derived from the original image content. The eye can form satisfactory saturation (C). Thus, the light provided in the dispersive outer frame AF can be distinguished, for example, into separate red and green regions, while the ambient light 3M generated by the active diffuser frame provides an interesting staged effect, It may be yellow. This is particularly enhanced when the distributed outer frame AF comprises a diffuser. This may produce object mode colors such as brown from light sources where brown is less likely to be produced, such as LED arrays.

Referring now to FIGS. 17 and 18, a basic schematic block diagram of an exemplary light flow in the embodiment shown in FIGS. 15 and 16, respectively, is shown. In FIG. 17, the light source (shown as the light source) and FIG. 18, the light source and some display light (shown as the display) emerge as RGB component light, or frame light as referred to in the appended claims, This light then passes through the light guide LG as shown and advances to the frame light modulator AM as shown, which is shown in green (G) as shown by a weakened rough arrow representing transmitted green light. ) To remove a portion of the light. This modulated light passes through a dispersive outer frame AF, and in our exemplary embodiment, they are mixed together to form magenta light (shown as magenta), which is broadcast to the surrounding space. This color difference selection is collected as a function of position on the distributed frame outer surface AS, using a known method for controlling the frame light modulator AM as a function of the behavior of the display D, collected from one or more active frame inputs. And can be modulated as a function of time.

FIG. 19 shows another embodiment similar in some ways to that shown in FIG. 16, wherein the active diffuser system supplements the video signal provided to the video display unit to produce modified video display light, and also in FIG. 11. It includes an exemplary angular photometric element as shown. This embodiment of the present invention is a video in which a CPU (not shown for clarity) resides in an origin region FA as shown in FIG. 1 to produce a modified display light K + as shown. Display output light K or video to generate a starting area video signal (discussed below) provided to video display unit D to drive or raise (or suppress upwards if necessary) the selected output pixels in the display unit. Allows the use of passive sensing of either of the display signals RF. This may allow for an increase in light generation, for example, because for the original display D there are now two new light sources, namely the modified light from the display and the light source LS in the active diffuser frame A as shown. This is because display light K + exists. As before, the modified display light K + and output light from the light source LS pass through the light guide LG and advance through the frame light modulator AM and the scattering outer frame AF. Some of this light in this illustrative example passes through the angular photometric element (AN) and produces what is now shown as the frame non-image angular photometric light 4M, which is a function of the viewing angle as shown. As a result, the characteristics can be changed.

In another embodiment of the invention, the light guide LG may allow the viewer to simultaneously transmit the original display light from the starting area FA and still pump or use the display light for use by the active diffuser frame system. Can be allowed.

Referring now to FIG. 20, one embodiment of this is illustrated using an enlarged cross-sectional view of an upper portion of the display D showing a starting area (not shown for clarity) with a splitter-prism equipped with an active diffuser frame system. Is shown. The light guide LG takes the form of a right prism as shown, and is thus formed to provide a critical surface where 100 percent internal reflection can occur.

Specifically, the light guide LG and / or the dispersive outer frame AF are formed as shown to allow for the presence of the critical surface CS at or near the critical angle for total internal reflection. The front face of the distributed outer frame AF shown on the right side of the figure is inclined such that its normal vector forms a critical surface CS about 45 degrees away from the normal output light outward direction D (K). Because the grain boundary angle for the internal reflection of most plastics is typically about 42 degrees, this provides an opportunity to split the light entering the light guide (LG), because using the selected terrain, the approximate Half will be beyond the critical angle, resulting in internally reflected output light KX as shown, and then passing through the frame light modulator AM mounted on top as shown, the frame modulated ambient light 3M. On the other hand, the other half of the light that enters the light guide LG is not thus redirected, but becomes the output light KT transmitted through the front as shown, and also becomes the frame image light 2. Thus, the observer will perceive or distinguish the original features of the original display image in the origin area FA, and still, at the same time, the light is available for pumping up from the dispersive outer frame AF for peripheral dispersion. This hollow or transparent active diffuser frame A thus allows the original display image to be viewed throughout the entire display area under reduced intensity, which is not specifically noted because of the inherent compensation system of the human visual system. . Small deflections from the straight exit to the transmitted output light KT are not shown for clarity.

This redirected internally reflected output light KX can be used as an input by the active diffuser frame system, adding information to the active diffuser frame A and any associated processor (not shown). It is possible to replace the display light sensor DS instead of the frame light modulator AM, or any combination of the two, in order to provide.

An additional feature is also shown, the use of the front reflector or reflecting surface T to reflect light internally inside the light guide LG to become ambient leakage light (shown as leakage). Such light may illuminate the back wall as shown in FIG. 8.

As an alternative embodiment to the divider prism embodiment illustrated in FIG. 20, FIG. 21 uses partial reflecting surface T2 instead of internal reflection at critical surface CS. As before, some light, i.e. the internally reflected output light KX, is passed through the active light diffuser frame A and / or alternatively to the display light sensor, such as by passing through the frame light modulator AM as shown. Reflected up for use as input to (DS) (not shown). The other light becomes the output light KT transmitted and transmitted as before. The light guide and the dispersive outer frame AF are now integrated into one physical block component here, so that most of them can be hollow as shown, with the optical path as previously shown in FIG. 20. . Using the partially reflective surface T2 may be advantageous as there is no refractive displacement effect on the image to be distinguished across the critical surface CS because there is an internal reflection refracted as shown in FIG. 20; Using a partially reflective surface can have the disadvantage of introducing some light loss at the reflective surface, while the 100 percent internal reflection at the critical surface CS of FIG. 20 is absolute. As in the previous FIG. 20, the front reflector T is used to enhance the backside leakage of ambient light as shown across the top of the display D. FIG. As an alternative to the continuous partially reflective surface T2, use selective reflectors or partial reflectors on a small physical scale that individually reflect and redirect some display light to leak, while the other light is frame image light 2. It may be allowed to pass between these select reflectors to add to it.

In general, the teachings given herein may be applied in a variety of ways. The divider prism shape for the light guide LG and / or the distributed outer frame AF may comprise one single plane with respect to the entire frame, alternatively the divider prism may each have a display origin boundary (see FIG. 1). It may include four planes, one for each side of, ie, top, bottom, left and right sides. Alternatively, there may be zone prisms or small prisms, even pixel-scale prisms, to achieve the same effect at a smaller scale.

The distributed outer frame AF also includes one or more light pipes (not shown) for specific purposes not shown or for further emitting or emitting ambient light at specific locations in the surrounding space. For example, the light pipe may be attached to the back of the dispersion outer frame AF, adjacent to where the leaked light exits back, as shown in FIG. 20 or 21. The ambient light M coming from such a light pipe can be optically pumped into other light structures for use elsewhere, such as floors with optical diffusers (not shown) or ceiling split units for special effects. have. Light pipes can also be used to carry light to amplify for the purpose of ambient dispersion.

One of the functions achievable by the present invention is the creation by the chromatic active frame, which is derived from the original display image light 1 but is not actually present. This can be done without relying on hot or active light sources, such as LEDs, which are difficult to control, even when the primary colors are combined, as mentioned previously. For example, the original display image light 1 may be color converted or color modulated. It should be noted that the luminance function of the human visual system provides detection sensitivity for various visible wavelengths, which varies as a function of light level.

For example, dark adaptation or night vision, which depends on rod cells, tends to be more sensitive to blue and green. Bright acclimation using cone cells is more suitable for detecting longer wavelength light, such as red or yellow. In dark home theater environments, this change in the relative luminance of the different colors as a function of light level can be offset to some extent by modulating or changing the color delivered to the video user in the surrounding space. This can be done using a color subtraction step using a frame light modulator AM, or can be done using the teachings of another embodiment of the invention shown in FIG. 22, in which the upper portion of FIG. Although shown, there are additional components, ie photoluminescent emitters for further modifying the light before ambient emission. Since the internally reflected output light KX as previously shown in FIG. 21 emerges upward in FIG. 22, it passes through the frame light modulator AM as before, and thereafter, as shown, the frame light modulator AM is shown. Ascend through the photoluminescent emitter (PE) attached, attached or integrated. As another example, and referring now to FIG. 23, a function similar to that shown in FIG. 15, further comprising a photoluminescent emitter PE interposed between the frame light modulator AM and the dispersion frame outer surface AS. Another embodiment of the present invention is shown. In this case, the output light from the light source LS passes through the light guide LG, passes through the frame light modulator AM, and is broadcast by the distributed referential frame AF in order to ambiently emit the surrounding space. Alternatively, the photoluminescent emitter PE may be integrated into the dispersive outer frame AF.

The photoluminescent emitter PE is excited by absorption, i.e. from incoming light from the light source LS or from the display output light K (e.g. KX), and then re-emits this light at a higher desired wavelength, Perform the conversion. Excitation and re-emission by photoluminescent emitters, such as fluorescent dyes, are new colors that do not originally exist in the original video image or light source, and are also probably not within the range or full range of colors inherent to the operation of the display D. Allows rendering of.

FIG. 24 shows a basic schematic block diagram of an exemplary light flow for this process, such as the embodiment given in FIG. 23. RGB light from a light source (shown as a display or light source) passes through a frame light modulator (AM), such as a TFT LCD display, and then onto a photoluminescent emitter (PE), where excitation, or absorption, at various wavelength ranges is { Additive mixing, for example, at the dispersion frame outer surface AS produces an orange color O that provides a new color (shown in orange boost) that does not originally exist in the display or light source.

The generation of new colors can provide new and interesting visual effects. An illustrative example may be the generation of orange light, such as the hunter's orange, for which available fluorescent dyes are well known (see ref [2]). The example given relates to one fluorescence color, in contrast to the general fluorescence and related phenomena, since the drawing would have otherwise focused on something that is not a specific example of a hunter's orange. In other words, any photoluminescent compound, material or material can be used for the photoluminescent emitter PE as long as it has an activation or excitation potential to respond to sources and light sources inside the active diffuser frame A. .

Using fluorescent oranges or other fluorescent pigment species may be particularly useful in low light conditions, where the rise in red and orange can offset the reduced sensitivity of dark adaptation time to long wavelengths.

Fluorescent pigments are proprietary pigments such as Peryllens, Naphthalimides, Komarins, Thioxanthines, Anthraquinones, Thioindigoids, and Day-Glo Color Corporation, Cleveland, Ohio. Pigments, such as known in the pigments may be included. Available colors include Apache Yellow, Tigris Yellow, Savannah Yellow, Pocono Yellow, Mohawk Yellow, Potomac Yellow, Marigold Orange, Ottawa Red, Volga Red, Salmon Pink, and Columbia Blue. These pigments can be included in resins such as PS, PET, and ABS using known processes.

Fluorescent pigments and raw materials can be designed to be significantly brighter than non-fluorescent materials of the same saturation, thereby enhancing the visual effect. The so-called durability problem of traditional organic pigments used to generate fluorescent colors is due to the recent technological advances that resulted in the development of durable fluorescent pigments that maintain their distinct color for 7 to 10 years of exposure to the sun. It was solved for over twenty years. Therefore, these pigments can hardly be destroyed in a home theater environment where UV light incident is minimized.

Alternatively, fluorescent photopigs can be used, which operate simply by absorbing short wavelengths of light and re-emitting this light as longer wavelengths, such as red or orange. Technically advanced inorganic pigments that are excited using visible light such as blue and purple, for example 400-440 nm light, are readily available.

Highly fluorescent materials provide uniquely colored light with unnatural brightness, known as fluorence, the psychophysical perception of fluorescence color phenomena.

This phenomenon remains largely unstudied, but the relationship between the maximum theoretically achievable luminance (relative to white) as a function of chromaticity has been quantitatively modeled by MacAdam (1935) and subsequently the macadam limit in color science records ( MacAdam limit). It is proposed that fluorescence can be specified by Y / YMacAdam (x, y). Where Y is the relative or apparent reflectance of the fluorescent color stimulus and YMacAdam (x, y) is the macadam limit for the chromaticity coordinates (x, y) of the fluorescent color stimulus.

FIG. 25 shows a comparison of conventional video color generation by conventional light sources or displays against the closest available saturation with the color conversion process of FIG. 24 in accordance with the present invention. As shown at left, the original video image or light source using primary colors R, G, and B produces a new orange color that cannot be uniquely produced by the display or light source as shown in FIG. This full range-outer light is shown as ambient light M +. Compare this to the generation of the same color of closest saturation using the light inherently generated by the display or light source, while by way of example, the high intensity of red light (shown as R) and green light (g Light containing the smaller intensity of the < RTI ID = 0.0 > < / RTI > is subtractively filtered by the frame light modulator AM to produce an orange color (shown in orange), which is still active diffuser frame A It is within the full range of colors inherently produceable by the display or light source connected with the. This figure graphically shows that the light generated by the active diffuser frame system using the photoluminescent emitter in accordance with the present invention may exceed the macadam limit for its saturation.

FIG. 26 shows a process in which fluorescent light emission can be used by the active diffuser frame of the present invention to produce color outside the full range of colors normally generated by a video display, in the form of a schematic block. RGB light from the display color gamut RGB is allowed to excite fluorescent material inside the photoluminescent emitter PE and is outside the full gamut of colors available by the unique operation of the display D or the light source LS. Allows the generation of color by the distributed outer frame AF. This is illustrated graphically in FIG. 26, where fluorescence causes the generation of out-of-gamut colors.

For illustrative purposes, FIG. 27 shows activation, reflection, fluorescence, and total power spectra for a fluorescent material (hunter's orange) that may be used for the embodiments illustrated by FIGS. 22, 23, 28, and 30. A prior art graph of variance is shown (from ref [2], p. 365). In this example, the photoluminescent emitter PE is excited by the shorter wavelength shown as E. The conventional reflection process shown by R is supplemented by the fluorescence emission spectral variance shown by F to provide a high-output total emission shown as HO, which is outside the intrinsic color full range of display D. Can be set to.

FIG. 28 shows a perspective cross-sectional view of a portion of a simple divider prism distributed outer frame AF integrated in a light guide LG. Some light from the light source, such as light source LS (not shown), or display output light K (not shown) may be reflected and not become frame image light 2, for example the blue light shown. Instead, this light is internally reflected and directed upwards in the figure towards the frame light modulator AM and subsequently passes through the photoluminescent emitter PE as shown at the top of the dispersive outer frame AF. This converts the light output (eg blue light) in a manner similar to that shown in the spectral dispersion graph of FIG. 27 to full-range orange light exiting into the ambient space as the peripheral frame non-image light 3 as shown. .

This process can easily generate ambient light outside the full range of colors inherent in the display D. Referring now to FIG. 29, two possible peripheral color or chromaticity coordinates, shown as M +, can be found on a standard CIE x-y chromaticity diagram, ie a color map. The map shows all colors known at maximum luminance as a function of chromatic coordinates x and y, with nanometer light wavelengths and CIE standard ore white points shown as reference. The saturation of the ambient color M + is easily shown to lie outside the full range of colors obtainable by the PAL / SECAM, NTSC, and Adobe RGB tristimulus color generation standards as shown.

The photoluminescent emitter PE incorporates a reflective fluorescent material, together with a diffused outer frame AF, which is formed and adapted to use reflection as a color modulation method within the active diffuser frame A, as well as absorb and re-emit only. You can.

It should also be noted that any number of known phosphors having a long relaxation time (eg longer than 10 ⁻⁸ seconds, eg 1 second) may be replaced or added to the fluorescent material in the photoluminescent emitter (PE). This may allow special effects, such as a time delay or drag in the progression of the luminance of the active diffuser frame A as scene elements played on the display. This effect allows the ambient light output shape to be scripted.

In another embodiment of the invention, FIG. 30 illustrates the angular photometric and angular chromatic elements (AN) to produce different optical colors, intensities and properties as a function of viewing angle theta and pi as shown. Another perspective cross-sectional view of a portion of a simple divider prism distributed outer frame AF additionally included but integrated with a light guide LG. Pi is measured in the horizontal plane, and theta θ is measured in the vertical plane. As shown, the simple divider prism used as a combination of the light guide LG and the dispersive outer frame AF is provided with input light (not shown) from a light source (not shown) such as light source LS or display output light K. R, G, B) is shown. As in the previous FIG. 28, some RGB light is internally reflected upwards and passes through the frame light modulator AM and the photoluminescent emitter PE, both of which may be optional. However, the light guide LG is here in optical communication with the angular photometric element AN, which is shown as part of the distributed outer frame AF and here as part of the front surface FF. Light from the photoluminescent emitter PE may exit the front face FF directly or may be reflected from the rear reflector RR, which helps guide light out of the front face FF. As shown, many color-differentiating effects are such as low intensity green light (g), and high intensity yellow light (Y), orange light (O), red light (R), and blue light (B). It can be established as a function of the viewing angle, shown schematically here as the illustrated light beam. In order to realize this effect, the angular photometric element AN in the form of the front surface FF may be a metallic or pearlescent permeable colorant; Iridescent materials using well known refractive or thin film interferences, such as using fish scale essences; Many known angular photometric and angular chromatic elements, such as guanine, or flakes of 2-aminohypoxanthine with preservatives, can be used alone or in combination. Pearlescent materials made from finely ground mica or oxide layers, bonite or malachite; Other materials may be used, such as metal pieces, glass pieces, plastic pieces, particulate matter, oils, crushed glass and pulverized plastics.

The front surface FF may be processed, formed or engraved to provide an angular photometric effect. For example, the front surface FF may include depressions, ribs, clouded areas, inclusions, including trapped air or particles, such as a piece of resin or glass. The angular photometric effect can be implemented through the use of either reflective or transmissive materials, as will be appreciated by those skilled in the art. It should also be noted that the embodiment shown in FIG. 11 may have weak photochromic properties due to the spectroscopic phenomena available by the use of prisms or lenses.

The effect of this active diffuser frame A is to change the optical properties very sensitively as a function of the observer's position when moving up or out of the chair, such as looking at a blue sparkle and later seeing red light. It can be a stage element.

To illustrate this, FIGS. 31 and 32 use the iridescent front face (FF), for the angular chromatic embodiment illustrated in FIG. 39, respectively, for the dominant color wavelength versus viewing angle pi and theta of the generated ambient light. A rectangular coordinate graph is shown. The wavelength and color of the light vary as a function of pi and theta, respectively.

Inclusion or other treatment of the front surface FF, including the inclusion of small color elements, allows the light intensity to vary angularly photometrically as shown in FIG. 33, which is not illustrated in FIG. 30. An orthogonal plot of the relative light intensity of the ambient light produced versus the viewing angle pi for an embodiment that is angular chromatic is shown.

In general, multiple optical elements, including small elements, can be used to multiplex the distributed outer frame. The simple configuration selected here for illustrative purposes should not be considered limiting in any way. Small light sources LS can be used, for example, with an internal structure that routes light to a specific position on the dispersion frame outer surface AS.

 Active diffuser frame system according to the present invention. It may be implemented in a larger context of the overall system, such as an entertainment center or computer peripherals. As discussed above, a processor or equivalent thereof for use in controlling the light source LS or for modulating the display output light K, or for generating a modified display light K +, may be provided within the display D. ; Can be located inside the active diffuser frame A, such as inside any light source LS, inside the light guide LG, or inside the distributed outer frame AF, or alternatively any of these It may be attached to or located external to any of these.

The control of the light source in the active diffuser frame A is carried out from one or more active frame inputs from the video display unit (display light, signals from a display light converter such as display light sensor DS, and resin from video display signal RF). Video content, which may be a function of many, and optionally also includes inputs that take into account viewing indoor or ambient space conditions, user preferences, or other optional input of information such as pre-recorded or transmitted screenplays. can do.

FIG. 34 shows another embodiment of the invention, similar to that shown in FIG. 15, but additionally including a frame contact sensor ST on the outer surface AS of the distributed outer frame AF. The frame connection sensor ST is substantially transparent and can also be fabricated using known techniques such as pressure sensitive semiconductor films, capacitive sensors, microphone technology, or planar switches, and also piezoelectric attached to the active diffuser frame A. Pure, as in the form of discrete accelerometers, such as accelerometers (not shown), or alternatively measuring contact with a conductive object such as the human body, such as when manually touching, rather than directly measuring vibration. For example, using known designs, such as in the form of capacitive sensors, it may take a different form than shown. Using a frame contact sensor ST for converting a contact, tap or other vibration into a transitional or other electrical or optical signal, the user can inform the processor (not shown) preference.

For example, connecting or tapping the active diffuser frame A is such that the characteristics of the resulting ambient frame light are not at all ambient light, with a more suppressed pattern and intensity, between the bright and fast moving light patterns on the distributed outer frame AF. Without them, it can cause them to toggle. In order to enable the active diffuser frame A to adjust the peripheral output for the desired effect, the conditions in the surrounding space around the display D can also be monitored. FIG. 35 shows an embodiment similar to that shown in FIG. 9 but additionally including an optical sensor and an acoustic sensor. The optical sensor SL is exemplarily shown on a distributed frame outer surface AS facing the viewer, and is a selenium photovoltaic cell or other photovoltaic cell, such as a silicon-germanium photosensitive cell, or other known photosensitive elements. It may include. Similarly, an acoustic sensor SS comprising any known kind of microphone or acoustic transducer can be integrated into the active diffuser frame A on the front side as shown.

There may be a number of light sources, including on or behind the distributed outer frame AF of the active diffuser frame A, including a flat array or display that is part of the active frame. The frame light modulator AM shown in the above figures may take the form of an LCD display (not shown) with or without backlight.

Referring now to FIG. 36, an enlarged schematic cross-sectional view of an upper portion of another embodiment of an active diffuser frame using two light sources is shown. In the upper left of the figure, a light source LS, such as an LED array, is positioned to allow the generation of ambient light M that is emitted up or back (to the left of the page) as shown, while the active diffuser frame A On the front side of the), an electroluminescent element EL is provided to produce a frame electroluminescent light 3EL towards the right side of the page towards the viewer (not shown). The frame contact sensor ST may also be integrated as shown. The electroluminescent element EL may comprise a flat panel array display and any other light emitting display such as an LCD may be used instead. Known electroluminescent devices such as shown in US Pat. No. 5,895,692 to Shirasaki et al. Can be used, wherein a fluorescent layer is applied on top of the electroluminescent device. The electroluminescent element EL may comprise a gas discharge lamp and a plasma display panel, or may utilize direct electroluminescence, such as the use of a display using a destriau effect phosphor, or any number of known charges Injection electroluminescent elements can be used.

Furthermore, the electroluminescent element EL is designed and formed to allow a graphical user interface (GUI) as shown to be provided on the front side or any other side of the active diffuser frame A, And frame touch sensor ST may be a touch-sensitive screen of known design that allows menu selection or other field-sensitive input from the user.

37, 38, and 39 may be referred to as processing modules or subcomponents that provide a more functional description and provide some way of illustration for embodiments of the present invention. As would be expected by those skilled in the field of electronics design, there are many possible configurations. The functional components given herein may be embedded independently or together on an electronics control module, chip, or processor or on multiple component circuit boards, and may also communicate using software, memory, and network cards. Such as interfacing with a referral processor.

37 is a functional schematic for control of an active diffuser frame system in accordance with the present invention that includes one active frame input that includes video content analysis that is subsequently used to affect the operation of any number of light sources. Shows. Solid lines with arrows may indicate signals such as control or electrical or optical signals. FIG. 37 clarifies some of the functions as shown in FIG. 38 and relates to light amplification and generation. In summary, in the figures, the processor receives a video display signal RF from the display D as previously shown in the component figures, and desired to be used to control the light source or light sources, such as a flat panel LED display or a frame light modulator. Video content analysis may be performed to generate or derive active frame light control signals or signals (shown as functional or physical modules or units, ie, video content analysis + active frame light control signals ). This includes simple analog signals, such as driver voltages to regulate the output of the LED device, or complex waveforms or digital frames or packets that make up the video signal itself, such as video signals used to control LED flat panel arrays or LCDs. can do. The final active frame light control signal or data (typically a large amount of data at high bit rates, indicated by double arrows) is fed to the optical amplification + generation board as shown. This interface may include a known driver, including a power transistor, needed to control any number of light sources, and as shown in this example, the interface may be a LED of known design. and controls the light source (shown as LED), (as shown by the different active light source) other active light source such as a plasma display panel or a laser bank, and the EL device (shown in electroluminescent devices). For example, it is expected that self-reference data can be obtained from these light sources, such as the current consumption for the LED array, and fed back to the optical amplification + generation board as shown (see single arrow).

As shown, the optical amplification + generation board can also control an LCD modulator or other frame optical modulator, and also as a set of scheduled to be broadcast in a particular manner or in a particular direction, as shown in the previous figures ( leakage ). A spill unit, which may include light, lamps, LEDs, or lasers, may be controlled as shown. In this example, it is also shown that data can flow back from the optical amplification + generation board to the video content analysis + active frame light control signal unit, such as for the purpose of collecting a history of broadcast ambient light.

38 illustrates a functional schematic for control of an active diffuser frame system in accordance with the present invention, including using a plurality of active frame inputs, wherein ambient conditions and user preferences are utilized. Transmission of control and other signals is shown using solid lines as before, while optical or light transmission is now shown using dashed lines. As before, a functional module, software module, or hardware module is shown, as shown, the video content + active frame light control signal has six inputs: passive detection of display light , active video signal pickoff , Receive any or all of the sensing (light and sound), frame contact or vibration sensing, user preferences, and active frame output history . This module also provides two outputs in this example, one for controlling the optical amplification + generation module as described above in FIG. 37, and the other for the display as a starting point area signal (FAS). It is. The starting area signal FAS is included in the active diffuser frame system or inside the display D to assist in driving the display output pixels residing in the starting area FA (shown as driving the display output pixels ). Supplied as a module. This optional process of driving display pixels in display D to produce modified display output light based on one or more active frame inputs is described in FIGS. 19, 40, and 41.

The modified display output light K + produced in this way by the display D is shown using dashed lines to selectively contribute to the passive optical input from the display as shown, naturally in a kind of feedback loop. The driving of the display output pixel in the starting area FA may contribute as shown to provide an associated input to the passive sensing of the display light and the active video signal pickoff as shown.

Passive optical input from the display can provide light for passive optical rebroadcast as shown, which can be directly directed to ambient light sent to observer Q as shown, and / or the light May contribute to or be modified by the optical amplification + generation module as shown, such as when passive light is subsequently modified by the frame light modulator AM. The light instantaneous + generating module generates three optical or light outputs: one output through a light source not explicitly shown in FIG. 38, such as using an LED as described in FIG. 37; Provide another output to a functional / physical module, such as a photoluminescent emitter (PE), as shown to provide fluorescence rise, full color gamut expansion as shown; As shown, a third output may be provided to a functional / physical module, such as an angular photometric element (AN), to provide an angular photometric + angular chromatic effect. The output light or ambient light finally generated by this module is shown at the bottom of this FIG. 38 as directed or available to the observer Q. FIG. Of course, in response to a signal in the active frame light control signal, it is generated thereby, such as an angled photometric element (AN) with a motor that changes the angle of the internal optics, such as the catch angle of the front face (FF) in FIG. 30. It does not exclude the modulation of the angular photometric element to change the properties of the emitted light.

FIG. 39 shows a similar schematic diagram of control of an active diffuser frame system according to the present invention, similar to that shown in FIG. 38 but also including video frame parsing and the use of a graphical user interface. As before, a functional module, software module, or hardware module is shown, and the video content analysis + active frame light control signal , as shown, may receive any or all of the six inputs previously discussed. Can be. However, as shown here, the frame output memory using known memory elements or elements advertises six inputs, which are now represented as the active frame output history table as shown. The frame output memory in turn obtains the information it needs from a surveillance function integrated within the video content analysis + active frame light control signal , which is designed to code or otherwise record and output the history of the ambient light control it provides. And / or can be programmed.

This history function is temporarily in response to the latest scene light generated by the display D, or after a certain color stimulus is shown on the active diffuser frame A, or in dark home theater environments if bright light was not. When introduced into the ambient space, it can be used to change (eg, color buffer or compensate) the ambient light. Well-known simultaneous color contrast compensation can be performed in this way. For example, if bright white light is projected onto a display that is uniformly illuminated with low intensity blue light (which can be detected by an indoor condition sensor such as light sensor SL), the white light will appear bright yellow. The blue light will have a more gray atmosphere if the two stimuli are provided independently. In essence the compensating hue is induced by adjacent illumination or stimulation. This is similar to continuous color contrast, such as when strong color stimuli, known as chromatic adaptation, induce a compensating hue for subsequently exposed stimuli. This can be important for home entertainment, and active diffuser frame systems can be used to compensate for ambient spatial light events, such as recent bright light, to affect frame color and intensity, and also active frame behavior in a satisfactory manner. The frame output memory can be used to continue the writing operation of the latest color and intensity provided on the display so as to affect the. In this way, recent video scenes containing bright white light followed by dark scenes containing blue light may affect the active diffuser frame system to use higher saturation blue for short periods of time during the visual adaptation process in the observer. Can be.

The user preference module now has two inputs: user preference values (memory) which can record and hold user preferences ; And as shown, it may, by its design, is shown to include a graphical user interface on the frame surface to provide coded affinity. In the context of larger systems, graphical user preferences or similar data can be downloaded to this memory or other active frame system memory using from a network such as a central server or satellite system.

Optical amplification and generation (using the associated light source) and passive optical rebroadcast of display light are not shown in FIG. 39, but as shown now the video content analysis + active frame light control signal module includes a video frame grabber + parse unit and Notified by the content modification unit . The video frame grabber + parse unit provides some desired characteristics of the video display signal (RF) in order to be able to provide data, perhaps simplified, to the content modification unit as shown, which is a radio frequency signal, or MPEG feed Whether it is a signal, it may include parsing individual video frames of the video display signal RF. This parsing can lead to overall hue and saturation as the average of the video content, and to specify rules for the desired effect.

The content modification unit provides the necessary data to the video content analysis + active frame light control signal module which allows for easy derivation of the active light control signal for the light source, not shown. This may include any particular color transformation into colors in the color space available by the use of a light source. The content transformation unit mounts a transformation matrix or equivalent thereof from the read-only memory (ROM) required, as well as any light source specific or content specific information required for rendering and characterization of the desired color within the generated ambient light. In order to do so, a modified data (memory) module as shown may be employed.

Appropriate deformation, if overall or localized edge effects are desired, such as, for example, the edge of the scattering frame outer surface AS closest to the display is dim, or has light of lower saturation chromaticity than the outer edge. Can be stored in the variant data memory and can be controlled according to user preferences. Deformation data also provides for localized light effects, such as tying together light from a wide input area to a particular area on the frame, or pumping light into the side area to project into the surrounding space or leak onto the back wall. Can be used to execute a transfer function that allows.

As mentioned, the active diffuser frame system according to the present invention is such that the video content analysis + active frame light control signal module can generate a starting area signal (FAS) which is used to influence the display (D). Active frame inputs as described may be allowed to be used. FIG. 40 is similar to that shown in FIG. 1, but the origin region video signal FAS is provided to the video display unit D to drive the origin output pixel UF shown as resident in the origin region FA. , Video display unit. The origin output pixel UF provides the display output light within the origin region KF, but after application of the origin region signal FAS, the video display signal RF driving the display is modified as described previously. It is supplemented to produce (K +). This modified display light can be used to increase the luminance output of the display output light K to enhance the passive display light entering the light guide LG. FIG. 41 shows a general schematic showing the combination of the original video signal RF and the video frame information for integrating the origin region video signal FAS for driving the selected origin output pixel UF in the video display unit. For analog waveforms, the summation of the start area signal FAS and the video display signal RF can be performed using a known method; In digital frames or packets, such as those used in the MPEG standard, a processor such as a processor (CPU) or other processor (not shown) may combine or permutate signals for driving display pixel U in a desired manner.

In addition to using the video information collected from the display D, the video content analysis + active frame light control signal module can analyze the sound provided with the video display signal RF, and also the sound level in the video program content. Depending on any desired structure that modulates the total intensity of ambient light M as a function of-in one mode that can be selected by the user, for example-the characteristic of ambient light M from active diffuser frame A can be changed. Can be. Accordingly, FIG. 42 shows a front schematic surface view of a display using an active frame A similar to that shown in FIG. 10, where the active frame ambient light M varies in response to video content as a function of time. Shows a broadcast pattern that may appear to be moving. For example, in a concert, a pattern may appear on the frame that rotates around the frame in response to an acoustic pattern, such as a basic beat or a drum beat. The illustrated active diffuser frame A has a pattern whose size and orientation can vary as a function of time.

FIG. 43 shows a Cartesian graph of relative luminance intensity versus time for an active diffuser frame system that modulates itself localized or general ambient light output in response to video content analysis, such as the component audio portion of video content. The oscillating luminance intensity variation shown may be responsive to the audio content of the video signal RF (not synchronized because there is no script required to operate the active diffuser frame system). Alternatively, the acoustic sensor SS as shown in FIG. 35 can sense loud music in the surrounding space and begin to wave the luminance intensity in response. In either case, the basic beats, drum beats, or other generalized or detectable patterns within the video content sound or similar detectable acoustic patterns present in the surrounding space may be imitated by the active diffuser frame A, which is It will appear to participate in the acoustic pattern in its own way.

In a similar manner, the acoustic sensor SS can be used to detect loud voices or continuous high noise levels, and this information can be used to derive the desired effect in the ambient light M generated by the active diffuser frame A. It can be used by video content analysis + active frame light control signal module. For example, loud voices or even laughter sounds can be detected by the acoustic sensor SS together with those provided by the video program content (the indigenous video program content sounds can be subtracted and eliminated by a subtraction unit not shown in the module circuitry). This may be a brilliant or high saturation hue in the ambient light M, or a high speed rolling or moving pattern in the dispersive outer frame AF as shown in FIG. 42, or vibration as shown in FIG. 43. Brightness can be derived. Similar glare effects can be triggered as a result of responding to high ambient spatial light levels detected by the light sensor SL. This splendor also shows that the fluorescent color, such as by modulating the use of the frame light modulator AM in the embodiment of FIG. 23 to increase or decrease the amount of activating light allowed to impinge on the photoluminescent emitter, is characterized in that the photoluminescent emitter ( To the extent allowed to be generated by PE).

The described graphical user interface, such as in FIG. 36, includes changing the degree of desired color fidelity; Varying splendor, including the extent to which any fluorescent color or color outside the full range is broadcast into the surrounding space; Turning on / off the active frame; Or change the preferences associated with system behavior, such as changing the general intensity level for the active diffuser frame A. The user preferences related to the brilliant and shiny motion of the active diffuser frame A versus the suppressed and low intensity motion are determined by the intensity or other nature of the video content received and analyzed by the video content analysis + active frame light control signal module. As with exaggerating changes, it may include the extent to which active frames respond to changes in video content quickly or significantly.

Advanced content analysis can produce suppressed tones in movies or content of certain characteristics. Video content that includes many dark scenes in the content can affect the behavior of the light source in the active frame, causing the ambient light to be broadcast to become dark, while the brilliant and bright tones can produce large amounts of sparkling tones. It can be used for certain other content, such as bright scenes (sunlit beaches, savanna tigers, etc.).

In general, an active diffuser system may include an optional adjustment screen or display type, such as a secondary display or a peripheral display, which can use an electroluminescent device for this purpose, which eliminates the need for a backlit LCD panel. Allows for a smaller, custom shape, such as a 2 centimeter-wide frame that complements the display D.
