Definitions
- This disclosure relates generally to optics, and in particular but not exclusively, relates to image generation.
- Displaying information is performed by monitors, televisions, and projectors, just to name a few.
- Large displays can be prohibitively expensive as the cost to manufacture display panels rises exponentially with display area. This exponential rise in cost arises from the increased complexity of large monolithic displays, the decrease in yields associated with large displays (a greater number of components must be defect free for large displays), and increased shipping, delivery, and setup costs.
- a scheme of tiling smaller display panels to form larger multi-panel displays is also sometimes used to display information, but that scheme is still quite costly and may include distracting seams between tiles.
- Projectors can generally project large images, but often suffer from poor contrast ratios.
- FIG. 1 illustrates an example block diagram configuration of a display system that stimulates a photoactive layer, in accordance with an embodiment of the disclosure.
- FIGS. 2A and 2B illustrate two possible examples of light directors that can be used in a display system, in accordance with an embodiment of the disclosure.

- Embodiments of a system and method for generating images from a backside of a photoactive layer are described herein.

- One skilled in the relevant art will recognize, however, that the techniques described herein can be practiced without one or more of the specific details, or with other methods, components, materials, etc.
- well-known structures, materials, or operations are not shown or described in detail to avoid obscuring certain aspects.
- FIG. 1 illustrates an example block diagram configuration of a display system 100 that stimulates a photoactive layer 133 to generate an image, in accordance with an embodiment of the disclosure.
- the illustrated display system 100 includes a light modulator 105 , wedge optical element 150 , light director 115 , and photoactive layer 133 .
- Light modulator 105 emits image-forming light 106 and is optically coupled to wedge optical element 150 .
- Wedge optical element 150 directs image-forming light 106 (via light director 115 ) to stimulate photoactive layer 133 to form an image displaying image light 199 .
- light modulator 105 includes a steerable laser that can be directed to the proper two-dimensional coordinates of the angled side of wedge optical element 150 to form an image on photoactive layer 133 .
- the laser may be capable of raster scanning and may be coupled to a servo motor.
- the laser is coupled with an electric lens to selectively focus the laser light onto the angled side of wedge optical element 150 .
- light modulator 105 includes a laser with micromirrors paired with micro-electro-mechanical systems (“MEMS”) actuators, such as Digital Light Processing (“DLPTM”) technology.
- MEMS micro-electro-mechanical systems
- DLPTM Digital Light Processing
- Light modulator 105 may include multiple lasers that are configured to emit laser light at different wavelengths where the wavelengths depend on the material in photoactive layer 133 .
- Possible photoactive materials include photoluminescent and photochromic materials. Photoluminescent materials absorb energy from photons from non-visible light and re-emit the energy from the photons as visible light. Photochromic materials are “reflective” in that they reflect visible (e.g. ambient) light and can be stimulated to change how they reflect the visible light, including reflecting specific colors of visible light. The stimulation of the photochromic materials may be done by visible light, and/or non-visible light (e.g. ultraviolet (“UV”), near-infrared (“NIR”), infrared (“IR”)).
- UV ultraviolet
- NIR near-infrared
- IR infrared
- a chemical composition known as Spiropyrans are stimulated with UV light, which causes a chemical reaction that makes the Spiropyran chemical reflect colored light.
- Another possible photoactive material would be a thermochromic material that changes the light the material absorbs/reflects based on its temperature.
- Photo-active materials or paints are available from companies such as DuPontTM, 3MTM, and others. Therefore, using photoluminescent, photochromic, and thermochromic materials separately or in combination offers a wide variety of ways to create an image and even color images on a photoactive surface.
- Light modulator 105 can be configured to include one or more of the appropriate light sources (e.g. lasers with different wavelengths) to stimulate an image on the photoactive material selected.
- the “decay time” of the material is the amount of time that the stimulation of the material affects the optical output or reflection of the material.
- Some of the decay times of the materials can be characterized as “half-lives” because of their rate of decay.
- the materials may have half-lives of 0.5 seconds, one second, or thirty minutes. When a material is first stimulated, it may turn black, but then fade to gray, and eventually white if it is not re-stimulated to turn black.
- the half-lives can vary depending on the particular chemical composition of the material. Some of the materials have more digital or bi-stable characteristics, meaning they don't slowly fade from black to white.
- these bi-stable materials may maintain a pigment or color until affirmatively switched back by a stimulus (e.g. certain temperature or wavelength).
- a stimulus e.g. certain temperature or wavelength
- a first stimulation e.g. light of a first wavelength
- a second, different stimulation e.g. light of a different wavelength than the first wavelength
- the material may be stimulated to a first color by stimulating the material with a first wavelength, which causes the material to reach a certain temperature that causes a chemical reaction.
- the thermochromic material may then need to be cooled by a different stimulus to cause the material to switch back to white. This may appear as erasing the image by a person that is viewing the thermochromic material.
- a photochromic compound is stimulated with a laser light of a first intensity to cause colorization of the photochromic compound and laser light of a second intensity stimulates the photochromic compound to cause de-colorization of the photochromic compound.
- a photochromic material may reflect different colors of light based on the wavelength of the stimuli. Hence, the same material can reflect red, green, and blue light if stimulated with the proper wavelength of light. Therefore, light modulator 105 may be configured with three or more steerable or guided lasers that can stimulate a material with different wavelengths of light to generate different colors for generating an image.
- the images displayed by display system 100 on photoactive layer 133 may not have the high refresh rate (e.g. 60 or 120 Hertz) required for watching sporting events or movies and may be best suited for displaying static or slow changing images.
- the decay time may give display system 100 a significant power advantage over conventional displays and projectors.
- photoactive layer 133 only needs to be re-stimulated or refreshed every ten seconds, while still maintaining an acceptable contrast ratio.
- different photoactive materials may have higher or lower half-lives.
- the watts per square inch needed to present an image using image generating system 100 may be orders of magnitude less than conventional displays and projectors due to the lower refresh rate required to maintain the image.
- light modulator 105 is optically coupled to wedge optical element 150 in a side-emitter configuration and directs image-forming light 106 toward an angled side of the wedge optical element.
- Wedge optical element 150 is made from a clear substrate and may be glass or plastic.
- the angled side of the wedge optical element reflects image-forming light 106 in the direction of light director 115 and image-forming light 106 propagates in the wedge optical element until the angle the image-forming light 106 strikes an interface between wedge optical element 150 and light director 115 is greater than the critical angle of Total Internal Reflection (“TIR”).
- TIR Total Internal Reflection
- each ray of image-forming light 106 would propagate normal to the backside surface of photoactive layer 133 to form a crisp image.
- the wrong pixel area of photoactive layer 133 may be stimulated; neighboring pixels may receive the stimulation intended because of the refracting angle. This unwanted effect may be called “directional bleed” or “spread” and negatively impact the image clarity of the desired image.
- light director 115 may assist in increasing the amount of image-forming light 106 that strikes the backside of photoactive layer 133 at an angle that is substantially normal.
- FIGS. 2A and 2B illustrate two possible examples of light director 115 , in accordance with an embodiment of the disclosure.
- FIG. 2A shows a light directing turning film 215 A.
- Turning films are commercially available and generally include optical structure (on the microscopic level) to bend light.
- light directing turning film 215 A doubles the bend of light to encourage the light to propagate substantially normal to the backside of photoactive layer 133 .
- FIG. 2B shows light directing glass bead 215 B, which may be incorporated in a film. Films that include glass beads may be available from 3MTM.
- the shape of glass beads 215 B optically couple image-forming light 106 to photoactive layer 133 in an optically efficient manner.
- the materials that glass beads 215 B are made from may be tuned to couple the particular wavelength or wavelengths of light emitted by light modulator 105 .
- glass beads are impregnated in the clear substrate of wedge optical element 150 .
- FIG. 3 illustrates an example block diagram configuration of display system 300 that stimulates photoactive layer 133 and uses a camera module 310 as feedback, in accordance with an embodiment of the disclosure.
- the illustrated display system 300 includes light modulator 105 , wedge optical element 150 , light director 115 , photoactive layer 133 , logic engine 315 , and camera module 310 as an environment input 330 .
- Display system 300 may also include environment inputs 330 which may include microphone 332 and proximity sensor 334 , as illustrated.
- Camera module 310 is positioned to monitor photoactive layer 133 and provides logic engine 315 feedback via image data sent to logic engine 315 through communication link 350 .
- Communication link 350 can be wireless or wired and may also be connected to network 375 .
- Logic engine 315 may analyze the image data and send a command to light modulator 105 , in response to analyzing the image data.
- Logic engine 150 may analyze the image data from camera module 310 for the contrast of the image displayed on photoactive layer 133 and cause light modulator 105 to increase or decrease the refresh rate of the image in response to the image data.
- Logic engine 315 may recognize a person (image recognition) using image data from camera module 310 and display images on the wall according to settings configured by the recognized person. Sports scores, stock tickers, weather reports, reminders, calendars, clocks, books, and recipes are possible images for display. Using the image data, logic engine 150 may recognize certain events (e.g. movement in the room) or contexts (ambient light brightness) and cause light modulator 105 to display information in response.
- events e.g. movement in the room
- contexts ambient light brightness
- logic engine 315 is coupled to microphone 332 to receive sound signals received by microphone 332 .
- Display system 300 (using logic engine 315 ) may recognize sounds using microphone 332 and display an image in response. It may respond to voice commands from a user.
- Display system 300 may recognize songs, televisions shows, or movies and display an image or series of images that correspond with the sound input received from microphone 332 .
- Proximity sensor 334 is configured to receive proximity signals from a tag and communicatively coupled to send a proximity alert signal to logic engine 315 when a “tag” is proximate to the proximity sensor.
- proximity sensor 334 may receive proximity signals from a “tag” located, for example, on a key chain or embedded in a mobile device, and display system 300 may display an image in response to receiving the proximity signals.
- environment inputs 330 may include more inputs and hardware than what is shown in FIG. 3 .
- Environment inputs 330 may include instruments to measure temperature data, humidity data, and/or atmospheric pressure.

Description
- This application claims priority under the provisions of 35 U.S.C. §119(e) to U.S. Provisional Application No. 61/636,458 filed on Apr. 20, 2012.
- This disclosure relates generally to optics, and in particular but not exclusively, relates to image generation.
- Displaying information is performed by monitors, televisions, and projectors, just to name a few. Large displays can be prohibitively expensive as the cost to manufacture display panels rises exponentially with display area. This exponential rise in cost arises from the increased complexity of large monolithic displays, the decrease in yields associated with large displays (a greater number of components must be defect free for large displays), and increased shipping, delivery, and setup costs. A scheme of tiling smaller display panels to form larger multi-panel displays is also sometimes used to display information, but that scheme is still quite costly and may include distracting seams between tiles. Projectors can generally project large images, but often suffer from poor contrast ratios. In addition, conventional technologies typically have high power consumption per square inch of displayed information, making displaying images on a large-scale quite costly, especially at acceptable contrast ratios. A display system capable of displaying high-contrast images (especially on a large-scale) with better power efficiencies than conventional technologies is desirable.

FIG. 1 illustrates an example block diagram configuration of adisplay system 100 that stimulates aphotoactive layer 133 to generate an image, in accordance with an embodiment of the disclosure. The illustrateddisplay system 100 includes alight modulator 105, wedgeoptical element 150,light director 115, andphotoactive layer 133.Light modulator 105 emits image-forminglight 106 and is optically coupled to wedgeoptical element 150. Wedgeoptical element 150 directs image-forming light 106 (via light director 115) to stimulatephotoactive layer 133 to form an image displayingimage light 199. - In one embodiment,
light modulator 105 includes a steerable laser that can be directed to the proper two-dimensional coordinates of the angled side of wedgeoptical element 150 to form an image onphotoactive layer 133. The laser may be capable of raster scanning and may be coupled to a servo motor. In one embodiment, the laser is coupled with an electric lens to selectively focus the laser light onto the angled side of wedgeoptical element 150. In one embodiment,light modulator 105 includes a laser with micromirrors paired with micro-electro-mechanical systems (“MEMS”) actuators, such as Digital Light Processing (“DLP™”) technology. The laser may be capable of modulating a duty cycle and/or intensity of the laser light output. -
Light modulator 105 may include multiple lasers that are configured to emit laser light at different wavelengths where the wavelengths depend on the material inphotoactive layer 133. Possible photoactive materials include photoluminescent and photochromic materials. Photoluminescent materials absorb energy from photons from non-visible light and re-emit the energy from the photons as visible light. Photochromic materials are “reflective” in that they reflect visible (e.g. ambient) light and can be stimulated to change how they reflect the visible light, including reflecting specific colors of visible light. The stimulation of the photochromic materials may be done by visible light, and/or non-visible light (e.g. ultraviolet (“UV”), near-infrared (“NIR”), infrared (“IR”)). In one example, a chemical composition known as Spiropyrans are stimulated with UV light, which causes a chemical reaction that makes the Spiropyran chemical reflect colored light. Another possible photoactive material would be a thermochromic material that changes the light the material absorbs/reflects based on its temperature. Photo-active materials or paints are available from companies such as DuPont™, 3M™, and others. Therefore, using photoluminescent, photochromic, and thermochromic materials separately or in combination offers a wide variety of ways to create an image and even color images on a photoactive surface.Light modulator 105 can be configured to include one or more of the appropriate light sources (e.g. lasers with different wavelengths) to stimulate an image on the photoactive material selected. - The “decay time” of the material is the amount of time that the stimulation of the material affects the optical output or reflection of the material. Some of the decay times of the materials can be characterized as “half-lives” because of their rate of decay. As an example, the materials may have half-lives of 0.5 seconds, one second, or thirty minutes. When a material is first stimulated, it may turn black, but then fade to gray, and eventually white if it is not re-stimulated to turn black. The half-lives can vary depending on the particular chemical composition of the material. Some of the materials have more digital or bi-stable characteristics, meaning they don't slowly fade from black to white. Rather, these bi-stable materials may maintain a pigment or color until affirmatively switched back by a stimulus (e.g. certain temperature or wavelength). For these materials, a first stimulation (e.g. light of a first wavelength) may stimulate the material to turn black or “ON”, while a second, different stimulation (e.g. light of a different wavelength than the first wavelength), may cause the material to turn white or “OFF.” For thermochromic materials, the material may be stimulated to a first color by stimulating the material with a first wavelength, which causes the material to reach a certain temperature that causes a chemical reaction. The thermochromic material may then need to be cooled by a different stimulus to cause the material to switch back to white. This may appear as erasing the image by a person that is viewing the thermochromic material.
- In one example, a photochromic compound is stimulated with a laser light of a first intensity to cause colorization of the photochromic compound and laser light of a second intensity stimulates the photochromic compound to cause de-colorization of the photochromic compound. In still another example, a photochromic material may reflect different colors of light based on the wavelength of the stimuli. Hence, the same material can reflect red, green, and blue light if stimulated with the proper wavelength of light. Therefore,
light modulator 105 may be configured with three or more steerable or guided lasers that can stimulate a material with different wavelengths of light to generate different colors for generating an image. - Due to the decay time of the photoactive material(s), the images displayed by
display system 100 onphotoactive layer 133 may not have the high refresh rate (e.g. 60 or 120 Hertz) required for watching sporting events or movies and may be best suited for displaying static or slow changing images. However, the decay time may give display system 100 a significant power advantage over conventional displays and projectors. In one example,photoactive layer 133 only needs to be re-stimulated or refreshed every ten seconds, while still maintaining an acceptable contrast ratio. Of course, different photoactive materials may have higher or lower half-lives. The watts per square inch needed to present an image usingimage generating system 100 may be orders of magnitude less than conventional displays and projectors due to the lower refresh rate required to maintain the image. - Referring to the illustrated embodiment in
FIG. 1 ,light modulator 105 is optically coupled to wedgeoptical element 150 in a side-emitter configuration and directs image-forminglight 106 toward an angled side of the wedge optical element. Wedgeoptical element 150 is made from a clear substrate and may be glass or plastic. The angled side of the wedge optical element reflects image-forming light 106 in the direction oflight director 115 and image-forminglight 106 propagates in the wedge optical element until the angle the image-forminglight 106 strikes an interface between wedgeoptical element 150 andlight director 115 is greater than the critical angle of Total Internal Reflection (“TIR”). - Ideally, each ray of image-forming
light 106 would propagate normal to the backside surface ofphotoactive layer 133 to form a crisp image. However, if enough of image-forminglight 106 propagates at angles that are substantially offset from normal to the targeted areas or pixel area ofphotoactive layer 133, the wrong pixel area ofphotoactive layer 133 may be stimulated; neighboring pixels may receive the stimulation intended because of the refracting angle. This unwanted effect may be called “directional bleed” or “spread” and negatively impact the image clarity of the desired image. To mitigate this problem,light director 115 may assist in increasing the amount of image-forminglight 106 that strikes the backside ofphotoactive layer 133 at an angle that is substantially normal. -
FIGS. 2A and 2B illustrate two possible examples oflight director 115, in accordance with an embodiment of the disclosure.FIG. 2A shows a lightdirecting turning film 215A. Turning films are commercially available and generally include optical structure (on the microscopic level) to bend light. In one example, lightdirecting turning film 215A doubles the bend of light to encourage the light to propagate substantially normal to the backside ofphotoactive layer 133.FIG. 2B shows light directing glass bead 215B, which may be incorporated in a film. Films that include glass beads may be available from 3M™. The shape of glass beads 215B optically couple image-forming light 106 tophotoactive layer 133 in an optically efficient manner. The materials that glass beads 215B are made from may be tuned to couple the particular wavelength or wavelengths of light emitted bylight modulator 105. In one embodiment, glass beads are impregnated in the clear substrate of wedgeoptical element 150. -
FIG. 3 illustrates an example block diagram configuration ofdisplay system 300 that stimulatesphotoactive layer 133 and uses a camera module 310 as feedback, in accordance with an embodiment of the disclosure. The illustrateddisplay system 300 includeslight modulator 105, wedgeoptical element 150,light director 115,photoactive layer 133,logic engine 315, and camera module 310 as anenvironment input 330.Display system 300 may also includeenvironment inputs 330 which may includemicrophone 332 andproximity sensor 334, as illustrated. - Camera module 310 is positioned to monitor
photoactive layer 133 and provideslogic engine 315 feedback via image data sent tologic engine 315 throughcommunication link 350.Communication link 350 can be wireless or wired and may also be connected tonetwork 375.Logic engine 315 may analyze the image data and send a command tolight modulator 105, in response to analyzing the image data.Logic engine 150 may analyze the image data from camera module 310 for the contrast of the image displayed onphotoactive layer 133 and causelight modulator 105 to increase or decrease the refresh rate of the image in response to the image data. -
Logic engine 315 may recognize a person (image recognition) using image data from camera module 310 and display images on the wall according to settings configured by the recognized person. Sports scores, stock tickers, weather reports, reminders, calendars, clocks, books, and recipes are possible images for display. Using the image data,logic engine 150 may recognize certain events (e.g. movement in the room) or contexts (ambient light brightness) and causelight modulator 105 to display information in response. - Still referring to
FIG. 3 ,logic engine 315 is coupled tomicrophone 332 to receive sound signals received bymicrophone 332. Display system 300 (using logic engine 315) may recognizesounds using microphone 332 and display an image in response. It may respond to voice commands from a user.Display system 300 may recognize songs, televisions shows, or movies and display an image or series of images that correspond with the sound input received frommicrophone 332.Proximity sensor 334 is configured to receive proximity signals from a tag and communicatively coupled to send a proximity alert signal tologic engine 315 when a “tag” is proximate to the proximity sensor. For example,proximity sensor 334 may receive proximity signals from a “tag” located, for example, on a key chain or embedded in a mobile device, anddisplay system 300 may display an image in response to receiving the proximity signals. It is appreciated thatenvironment inputs 330 may include more inputs and hardware than what is shown inFIG. 3 .Environment inputs 330 may include instruments to measure temperature data, humidity data, and/or atmospheric pressure.Logic engine 315 may include a processor a Field Programmable Gate Array (“FPGA”), or other logic for processing image data andenvironment inputs 330.Logic engine 315 may include memory to store settings, images, and image data received from camera module 310. - A user may be able to communicate with display system 300 (via network 375) with a mobile device or personal computer. A user may be able to change the images or theme of the images displayed by
display system 300.Display system 300 may include a BlueTooth or other wireless interface (not shown) for mobile device interface. - It is appreciated that
display system 100 could be built into a wall or sold as a panel display.Display system 300 could also be built into a wall or sold as a panel display with camera module 310 being positioned separately to monitor the image displayed onphotoactive layer 133. -
FIG. 4 shows an example configuration of aphotoactive layer 133 that includes different photoactive materials arranged in a pattern having pixels and sub-pixels, in accordance with an embodiment of the disclosure.FIG. 4 shows a view from the frontside ofphotoactive layer 133. In the upper left corner,FIG. 4 shows a zoomed in view of a pixel ofphotoactive layer 133 having a first color sub-pixel 406, asecond color sub-pixel 411, and athird color sub-pixel 416. Different photoactive materials that emit or reflect different colors of light (e.g. red, green, and blue) are disposed, separately, in the sub-pixels. Thelight modulator 105 will stimulate the sub-pixels on an individual basis to generate a perceived color of each pixel to form an image. The intensity or duration of stimulation of first color sub-pixel 406,second color sub-pixel 411, andthird color sub-pixel 416 may be varied to get the desired color from the pixel. The intensity of the stimulation may be varied by changing a duty cycle of the emitted laser light. - When the first color sub pixels 406 are stimulated, they subsequently emit or reflect a first color (e.g. red) light for a period of time, when the second
color sub pixels 411 are stimulated, they subsequently emit or reflect the second color (e.g. green) light for a period of time, and when the thirdcolor sub pixels 416 are stimulated, they subsequently emit or reflect the third color (e.g. blue) light for a period of time. By aligning or timing image-forming light 106 fromlight modulator 105 with the different sub-pixels, the appearance of color images and videos may be created. Of course, other color combinations may be used. By arranging three different colors of photoactive paint onphotoactive layer 133, a color display may be created in conjunction withlight modulator 105 having a laser of a single wavelength to stimulate the three different colors of photoactive paint to generate a color image. -
FIG. 5 is a flow chart illustrating aprocess 500 of generating an image on a photoactive surface, in accordance with an embodiment of the disclosure. The order in which some or all of the process blocks appear inprocess 500 should not be deemed limiting. Rather, one of ordinary skill in the art having the benefit of the present disclosure will understand that some of the process blocks may be executed in a variety of orders not illustrated, or even in parallel. - In
process block 505, image-forming light (e.g. image-forming light 106) is directed to a backside of a photoactive layer to generate an image on a frontside of the photoactive layer (e.g. photoactive layer 133). In one example, directing the image-forming light to the backside of thephotoactive layer 133 may include directing image-forming light to an angled side of a wedge optical element having a clear substrate. In that example, a light director layer receives the image-forming light from the angled side of the wedge optical element and couples the image-forming light to the backside of the photoactive layer in an optically efficient manner. Inprocess block 510, a camera module monitors the image from a frontside of the photoactive layer. The image data is analyzed inprocess block 515. Inprocess block 520, the image on the frontside of thephotoactive layer 133 is completed or refreshed by directing additional image-forming light to the backside of the photoactive layer. The completing or refreshing of the image is in response to the analyzed image data. In one embodiment, the refresh rate of the image is based on a contrast ratio of the image. Afterprocess block 520, the process may return to process block 510. - The processes explained above are described in terms of computer software and hardware. The techniques described may constitute machine-executable instructions embodied within a tangible or non-transitory machine (e.g., computer) readable storage medium, that when executed by a machine will cause the machine to perform the operations described. Additionally, the processes may be embodied within hardware, such as an application specific integrated circuit (“ASIC”) or otherwise.
- A tangible non-transitory machine-readable storage medium includes any mechanism that provides (i.e., stores) information in a form accessible by a machine (e.g., a computer, network device, personal digital assistant, manufacturing tool, any device with a set of one or more processors, etc.). For example, a machine-readable storage medium includes recordable/non-recordable media (e.g., read only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices, etc.).
