Description

Optical sensor stereo display system

The present invention relates to an optical sensing stereoscopic display system, which is a system for displaying stereoscopic images.

With the development of science and technology, image display technology is constantly innovating. People are no longer pursuing just flat images, but are constantly improving from 3D technology to 4D, 5D and even more immersive experiences.

3D imaging technology has been developing for decades. Current 3D displays or projection devices mostly rely on active or passive 3D wearable devices (e.g., 3D glasses) to achieve 3D stereoscopic imaging. Wearing a 3D wearable device can conflict with existing myopic glasses and can also cause dizziness and discomfort.

The most direct way to solve these problems is to present digital information in 3D stereoscopic form without wearing a 3D wearable device. Although screen angle polarization technology currently allows viewers to directly view 3D stereoscopic images without wearing any equipment, the image input format must be processed, and there are also distance and angle limitations on the imaging. Therefore, there is still considerable room for improvement.

The system of the present invention uses optical sensing to allow viewers to view 3D stereoscopic images without wearing a 3D wearable device.

The optical sensing stereoscopic display system of the present invention comprises a color light sensing panel, a stereoscopic display panel, and a control panel. The color light sensing panel is used to sense the color light of an image. The color light sensing panel has a sensing surface, a plurality of color zones, and a plurality of color light sensing elements. The sensing surface is located on one side of the color light sensing panel. The color zones are evenly distributed on the sensing surface. The sensing surface is used to display the image, and the image can completely cover the color zones, so that each color zone has a color block corresponding to the image. The color light sensing elements are respectively installed in the color zones and are used to sense the color light and convert it into an electronic signal. The 3D display panel is used to present a 3D image. The 3D display panel is constructed from a plurality of 3D display modules. The 3D display panel is adjacent to one side of the color light sensor panel. The number of 3D display modules is the same as the number of color zones, and the positions of the 3D display modules and the color zones correspond to each other. There is a bit difference between the 3D display modules, which enables the 3D display panel to present a 3D image. The control panel is used to convert the electronic signals and provide at least one value signal to the stereoscopic display panel. The control panel has a signal transceiver element, a signal conversion element and a database. The signal transceiver element is electrically connected to the color light sensing elements, the stereoscopic display modules and the signal conversion element, and the signal conversion element is electrically connected to the database.

The signal transceiver element receives the electronic signals and transmits them to the signal conversion element. The signal conversion element converts the electronic signals into equal-value signals and transmits them to the signal transceiver element. The signal transceiver element transmits the equal-value signals to the 3D display modules. The 3D display modules are displaced or deformed in response to the equal-value signals. This displacement or deformation creates a height difference between the 3D display modules, ultimately creating a concave-convex surface on the 3D display panel to present a 3D image.

This invention presents 3D images more intuitively, allowing viewers to see them with their naked eyes without the need for any assistive devices. This eliminates the discomfort associated with wearing assistive devices (e.g., 3D glasses) and eliminates the viewing distance and angle restrictions associated with wearing assistive devices.

In a preferred embodiment, the image is projected onto the sensing surface via a projector.

In a preferred embodiment, the image is displayed on the sensing surface via a display.

In a preferred embodiment, the three-dimensional display modules form the potential differences by displacement.

In a preferred embodiment, the three-dimensional display module has a displacement block, a microactuator and an actuator control element. The displacement block is fixed to one end of the microactuator. The microactuator is electrically connected to the actuator control element. The actuator control element is electrically connected to the signal transceiver element to receive the equal-value signal. The content of the equal-value signal controls the microactuator to drive the displacement block to perform linear displacement in one direction.

In a preferred embodiment, the three-dimensional display modules form the potential differences by deformation.

In a preferred embodiment, the 3D display module comprises a deformable block, a heater, and a heater control element. The deformable block is fixed to one end of the heater and can be deformed by temperature. The heater is electrically connected to the heater control element, which is in turn electrically connected to the signal transceiver element to receive the equal-value signal. The equal-value signal is used to control the heater to heat the deformable block to a certain temperature, causing the deformable block to change shape due to the heat.

In a preferred embodiment, the deformation block is selected from a polymer material, a metal alloy material or a ceramic material with a high thermal expansion coefficient that is sensitive to temperature changes.

Other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

As used herein, the articles "a," "an," and "any" refer to one or more than one (i.e., at least one) items without specifying a specific quantity. For example, "an element" means one element or more than one element.

In the diagrams in this article, the proportions are shown as partial enlargements to clearly present the microscopic structure.

Please refer to Figure 1, as shown in the figure, it includes a color light sensor board 1, a stereo display board 2, and a control board 3. The color light sensor board 1 is used to sense the color light of an image, and its color light information can be transmitted to the control board 3. The control board 3 provides a signal to the stereo display board 2, so that the stereo display board 2 can present a three-dimensional image through its signal.

Please refer to Figure 2 for the design of the color light sensor board 1. As shown in the figure, the color light sensor board 1 comprises a sensing surface 11, a plurality of color zones 12, and a plurality of color light sensing elements 13. In this embodiment, the sensing surface 11 is located on one side of the color light sensor board 1. The color zones 12 are evenly distributed on the sensing surface 11 and arranged in a matrix. The sensing surface 11 is used to display a light source or image. The light source or image completely covers each color zone 12, so that each color zone 12 contains a color block corresponding to the light source or image. In one example, the light source or image is displayed on the sensing surface 11 through projection. A projector is set up in front of the sensing surface 11, and the light source or image can be projected onto the sensing surface 11. In other examples, the sensing surface 11 can also be a display (such as a liquid crystal display), so that the light source or image can be directly displayed on the sensing surface 11. It is worth mentioning that whether the light source or image is realized through a projector or a monitor, the only difference between the two is the source direction of the light source or image. However, the light source or image completely covers each color area 12, so that each color area 12 has a color block corresponding to the light source or the image. In other possible embodiments, the light source or image can also be displayed on the sensing surface 11 through non-projection or direct display, and this embodiment is not limited thereto.

Next, a color sensor 13 is installed in each color zone 12. The color sensor 13 is used to sense the three primary colors of light (RGB) and convert it into an electronic signal. In this embodiment, the color light comes from a projector, display, or other light source or image displayed on the sensing surface 11. In practice, the color sensor 13 can convert the color light into an electronic signal through a color filter. The color filter can filter out the R, G, or B color bands (whether it is a single color or a switching of multiple colors), and then generate a corresponding signal based on the strength of the filtered band. For example, a blue light is incident on one of the color zones 12 and passes through the color sensor 13 in that zone. Based on the wavelength of the blue B light, the blue light is detected as (R 0, G 0, B 255). In another example, an orange light is incident on another color zone 12 and passes through the color sensor 13 in that zone. Based on the wavelength of the orange R and G light, the orange light is detected as (R 255, G 97, B 0).

The 3D display panel 2 is constructed from a plurality of 3D display modules 21, each arranged in a matrix. The 3D display panel 2 is adjacent to one side of the color light sensor panel 1. Each 3D display module 21 has the same number of color zones 12, and the positions of each 3D display module 21 and each color zone 12 correspond to each other. In other words, each 3D display module 21 has a corresponding color zone 12. Each 3D display module 21 can be displaced or changed in shape, creating a length difference between the 3D display modules 21. This further gives the 3D display panel 2 the appearance of a concave and convex surface, thereby presenting a three-dimensional image. In this embodiment, the main body of the 3D display module 21 is made of a light-transmitting material. This allows light or images to pass through each 3D display module 21 and be displayed on the sensing surface 11. In other embodiments, the main body of the 3D display module 21 is made of a non-light-transmitting material. In this way, light or images do not need to pass through each 3D display module 21 to be displayed on the sensing surface 11.

The 3D display module 21 has two ways of changing: displacement or shape, to achieve a three-dimensional image on the 3D display panel 2. These are: A. Displacement change is produced through a mechanical structure. Please refer to Figure 3. As shown in the figure, the mechanical 3D display module 21 includes a displacement block 211, a microactuator 212, and an actuator control element 213. The displacement block 211 is fixed to one end of the microactuator 212. The microactuator 212 is electrically connected to the actuator control element 213. The actuator control element 213 can receive a signal and control the microactuator 212 based on the content of the signal, so that the microactuator 212 can drive the displacement block 211 to perform a linear displacement in a certain direction. The microactuator 212 can be an electrostatic actuator (electrostatic acutator). An electrostatic actuator uses a large number of cross-arranged comb electrodes as parallel plates of a capacitor. When a bias is applied between the movable and fixed comb electrodes, an electrostatic attraction is generated, thereby causing displacement. The displacement block 211 can be fixed to the end of the electrostatic actuator that generates displacement. In other embodiments, the microactuator 212 may also be a thermal actuator, a magnetic actuator, a piezoelectric actuator, a scratch drive actuator (SDA), or other driving devices capable of providing linear displacement. As long as the microactuator 212 can drive the displacement block 211 to linearly displace in a certain direction, it falls within the scope of the microactuator 212 of this embodiment, and this embodiment is not limited thereto. B. Shape change is a change produced by a structural change in the material. Referring to FIG. 4 , the shape-changing 3D display module 21 includes a deformation block 214, a heater 215, and a heater control element 216. The deformation block 214 is fixed to one end of the heater 215. The deformation block 214 can be deformed by temperature. The heater 215 is electrically connected to the heater control element 216. The heater control element 216 can receive a signal and control the heater 215 according to the content of the signal. The heater 215 can heat the deformation block 214 to a temperature according to the instruction of the signal, so that the deformation block 214 is heated and changes in shape due to changes in the material structure. The deformable block 214 is made of a polymer material with a high thermal expansion coefficient and memory properties that are sensitive to temperature changes. Simply put, this polymer material easily changes shape due to molecular expansion or contraction when the temperature changes (e.g., heating or cooling). If the temperature stops changing, the material temporarily remains in its deformed shape. Then, when the temperature changes again, the material returns to its original shape. Therefore, the deformable block 214 can be heated by the heater 215 to produce a shape change. The material can be a polymer material (e.g., thermotropic shape memory polymer, electrotropic shape memory polymer, phototropic shape memory polymer, chemically induced shape memory polymer, etc.). Alternatively, the deformable block 214 may be a metal alloy (e.g., titanium-nickel alloy), a ceramic material, or any other structure that can be deformed by temperature changes. As long as the deformable block 214 can change shape in response to temperature changes, the deformable block 214 of this embodiment is not limited thereto. Furthermore, the heater 215 may be a micro heater.

Please refer to Figure 5 for the design of the control panel 3. As shown in the figure, the control panel 3 has a signal transceiver element 31, a signal conversion element 32 and a database 33 inside. The signal transceiver element 31 is electrically connected to each color light sensor element 13 and the actuator control element 213 or heater control element 216 of each stereoscopic display module 21. The signal transceiver element 31 is in turn electrically connected to the signal conversion element 32, which is electrically connected to the database 33. The signal transceiver element 31 can receive each color light signal sensed by each color light sensing element 13 and transmit its signal to the signal conversion element 32. The signal conversion element 32 can search the database 33 for the value that matches its color light signal, and then convert its value into a signal and transmit it to the signal transceiver element 31. The signal transceiver element 31 then transmits its value signal to the actuator control element 213 or the heater control element 216 of each three-dimensional display module 21, so that the actuator control element 213 can control the micro-actuator 212 according to its value signal, or the heater control element 216 can control the heater 215 according to its value signal.

It is worth mentioning that the database 33 is pre-keyed with the displacement or deformation corresponding to each color of light. In practice, the 256 colors of RGB can be keyed in. If a mechanical 3D display module 21 is used, then each of the 256 colors has a corresponding displacement; or, if a shape-changing 3D display module 21 is used, then each of the 256 colors has a corresponding deformation.

The following are three different implementation scenarios of the present invention (the three-dimensional display module 21 in the following three embodiments is illustrated by mechanical displacement changes, and other types of three-dimensional display modules 21 can be arbitrarily replaced): A. Please refer to Figures 6A and 6B. As shown in the figure, a projector 4 is set to project an image A1 onto the sensing surface 11. In each color area 12, there is a color block A11 of a portion of the image A1, and the color light sensing element 13 can sense the color light of the color block A11 and convert it into a color light signal B1. The color light signal B1 sensed by the color light sensing element 13 can be transmitted to the signal transceiver element 31, which then transmits its color light signal B1 to the signal conversion element 32. The signal conversion element 32 can search the database 33 for a value that matches its color light signal B1, and then convert its value into a value signal C1 and transmit it to the signal transceiver element 31. The signal transceiver element 31 then transmits its value signal C1 to the actuator control element 213 of each 3D display module 21, so that the actuator control element 213 can control the micro actuator 212 according to its value signal C1, and further, the micro actuator 212 drives the displacement block 211 to perform a linear displacement in one direction. In this way, each color light sensor 13 senses the color light of a different color block A11. Ultimately, each displacement block 211 shifts the corresponding color light by the amount of light, creating a 3D image with various concave and convex variations in the appearance of the entire 3D display panel 2. B. Referring to Figures 7A and 7B, a liquid crystal display 5 is provided, and the color light sensor panel 1 is mounted on the liquid crystal display 5. An image A2 is displayed on the sensing surface 11 through the liquid crystal display 5. Each color region 12 contains a color block A21 representing a portion of image A2. The color light sensor 13 senses the color light of the color block A21 and converts it into a color light signal B2. The color light signal B2 sensed by the color light sensing element 13 can be transmitted to the signal transceiver element 31, which then transmits its color light signal B2 to the signal conversion element 32. The signal conversion element 32 can search the database 33 for a value that matches its color light signal B2, and then convert its value into a value signal C2 and transmit it to the signal transceiver element 31. The signal transceiver element 31 then transmits its value signal C2 to the actuator control element 213 of each 3D display module 21, so that the actuator control element 213 can control the micro actuator 212 according to its value signal C2, and further, the micro actuator 212 drives the displacement block 211 to perform a linear displacement in one direction. In this way, each color light sensing element 13 senses the color light of a different color block A21. Ultimately, each displacement block 211 shifts the value of the corresponding color light, allowing the entire three-dimensional display board 2 to form a three-dimensional image with many concave and convex changes in appearance. C. Please refer to Figures 8A and 8B. As shown in the figure, an external device 6 is set. The external device 6 can be a mobile phone, tablet computer, computer or other device that can read or transmit an image A3. The external device 6 is electrically connected to the signal conversion element 32, and the image A3 is transmitted to the signal conversion element 32 through the external device 6. The signal conversion element 32 can then search the database 33 for a signal that matches its color light signal B3. The corresponding magnitude is converted into a magnitude signal C3 and transmitted to the signal transceiver 31. The signal transceiver 31 then transmits the magnitude signal C3 to the actuator control element 213 of each 3D display module 21. The actuator control element 213 controls the micro-actuator 212 according to the magnitude signal C3. The micro-actuator 212 then drives the displacement block 211 to linearly shift in a certain direction. Ultimately, each displacement block 211 shifts by the magnitude of the corresponding color light, creating a 3D image with a variety of concave and convex shapes on the entire 3D display panel 2.

In the above embodiments, the light source or image, image A1, image A2 or image A3, can be any type of image presented by colored light, and can be static or dynamic.

Compared to other conventional technologies, the optically-sensitive stereoscopic display system provided by this invention offers a primary advantage: it presents stereoscopic images more intuitively, allowing viewers to see them with their naked eyes without the need for any assistive devices. This eliminates the discomfort associated with wearing assistive devices (e.g., 3D glasses) and eliminates viewing distance and angle restrictions associated with the use of assistive devices.
