[0026] V: Equipment Detailed Implementation

[0027] The following disclosure provides numerous different embodiments or examples for implementing various features of the provided invention. The embodiments of components and configurations described below are merely examples and are not intended to be limiting. Furthermore, for simplicity and clarity, reference numerals and / or designations are repeated in the examples, but this does not in itself limit the relationship between the various embodiments and / or components discussed.

[0028] Please refer to Figure 1 , Figure 1 This is a schematic diagram of an electronic paper display system 100 according to an embodiment of the present invention. The electronic paper display system 100 is applicable to any device surface, clothing, and mobile vehicle, including but not limited to drones, vehicles, aircraft, rescue equipment, precision shooting tools, etc., or any device requiring visual concealment. Figure 1 In the example, the electronic paper display system 100 is used on the surface of the device V (e.g., the surface of a drone) and includes an electronic paper display panel 110, an image capturing device 120, and a processor 130.

[0029] The electronic paper display panel 110 is shaped and covers the entire surface of the device V and is configured to display the desired colors. The electronic paper display panel 110 is flexible and bendable, allowing it to conform appropriately to the appearance of the device V. Figure 1 In the example shown, the e-paper display panel 110 is only attached to the main surface of the drone. In other examples, the e-paper display panel 110 may also be completely attached to the entire drone, such as to the fan blades, support frame, fan blade bearings, etc.

[0030] In some embodiments, the electronic paper display panel 110 is formed by attaching electronic ink to a thin-film transistor (TFT) substrate. Alternatively, the electronic paper display panel 110 may be a segmented display, with each segment corresponding to a driving line, so that the desired pattern can be pieced together by multiple segments.

[0031] The image capturing device 120 is configured to capture the environment in which the device V is located and generate an environmental image P. The image capturing device 120 includes, but is not limited to, a digital camera, a network surveillance camera (IP camera), a charge-coupled device (CCD) camera, a complementary metal-oxide-semiconductor (CMOS) camera, or other devices for capturing images or pictures.

[0032] In some embodiments, the image capturing device 120 is a rotatable image capturing device, which can be rotated to different positions to capture the surrounding environment of the device V and generate several environmental images P corresponding to these positions. In some embodiments, the image capturing device 120 also includes close-up and long-range adjustment functions to obtain a complete environmental image P of the environment in which the military device V is located.

[0033] It should be understood that, although Figure 1 The image capturing device 120 shown is depicted above the main unit of the drone, but in fact, without affecting the acquisition of environmental images P, the image capturing device 120 can be placed in other locations on the drone as needed, and is not limited to above the main unit of the drone.

[0034] The processor 130 is electrically connected to the image capturing device 120 and the electronic paper display panel 110, and is configured to receive the environmental image P captured by the image capturing device 120. The processor 130 can train an artificial intelligence model using a color recognition algorithm, so that the trained artificial intelligence model can automatically generate control signals to adjust the display color and pattern of the electronic paper display panel 110 based on the received environmental image P. In this way, the electronic paper display panel 110 can change the color displayed on the surface of the device V according to this control signal, or further change the surface pattern, so that the color and pattern of the surface of the device V are similar to the outline and color of objects in the environment, thereby concealing itself in the surrounding environment.

[0035] The aforementioned "color similarity" means that after the grayscale value of the electronic paper display panel 110 is adjusted, the displayed color can be as close as possible to the perceived ambient color. For example, the processor 130 identifies the ambient color based on the ambient image P and selects the closest, or within an acceptable range, grayscale value to generate a control signal, so that the color of the device V's surface, after being adjusted by the control signal, can be close to the ambient color. The device V can also further adjust the surface pattern to improve its camouflage effect. For example, when the device V is flying in a forest, it can change its surface color to green and further display leaves on the surface; or when it is hovering over a branch, it can change its surface color to brown and display the tree's texture on the surface to increase the camouflage effect.

[0036] In embodiments of the present invention, the color recognition algorithm includes neural networks, region-based color analysis, and color difference calculation. Through these algorithms, the processor 130 can automatically identify the color of the environmental image P and calculate the corresponding control signal to adjust the color of the device V's surface to be similar to the environmental color.

[0037] In an embodiment of the present invention, the electronic paper display system 100 further includes a driving circuit (not shown). The driving circuit is electrically connected between the processor 130 and the electronic paper display panel 110, and is configured to generate a corresponding driving signal according to a control signal to drive the electronic paper display panel 110 to display a color similar to the ambient color.

[0038] In an embodiment of the present invention, the electronic paper display system 100 further includes a power supply system (not shown). The power supply system is used to supply DC or AC power required by the electronic paper display panel 110, the image capturing device 120, and the processor 130.

[0039] In embodiments of the present invention, the processor 130 may be embedded in the device V and form a modular integrated circuit with the electronic paper display panel 110, the driving circuit, and the power supply system, but the present invention is not limited thereto. In embodiments of the present invention, the image capturing device 120 can automatically identify the ambient color without communicating with the ground host and change the appearance color of the device V in real time according to the ambient image P.

[0040] In some embodiments, the processor 130 is further configured to adjust the shooting angle, orientation, magnification of distant scenes, and magnification of near scenes of the image capturing device 120. For example, in an embodiment where the electronic paper display panel 110 includes multiple display areas, when the processor 130 cannot identify the ambient colors corresponding to these display areas from the ambient image P, it can generate adjustment signals to adjust the shooting angle, orientation, magnification of distant / near scenes, etc. of the image capturing device 120, so as to re-obtain one or more identifiable ambient images P.

[0041] In embodiments of the present invention, the electronic paper display panel 110 includes a plurality of display areas. For example, the electronic paper display panel 110 may be divided into multiple display areas, which are respectively attached to different positions on the surface of the device V. Each display area can be independently controlled by the processor 130, thereby exhibiting more delicate display colors. In such an embodiment, the processor 130 is further used to generate several control signals corresponding to these display areas based on one or more environmental images P. Therefore, each display area can display a color similar to the adjacent environmental color according to the corresponding control signal. Alternatively, each display area can display a pattern according to the corresponding control signal, so that the pattern on the surface of the device V at different positions is similar to the outline of objects in the adjacent environment.

[0042] In an embodiment of the present invention, the electronic paper display panel 110 includes a deformable substrate, a stretchable electrode layer, and a stretchable electrophoretic display dielectric layer, thereby enabling the electronic paper display panel 110 to be further stereolithographically formed on the surface of a device V of different shapes.

[0043] Please refer to Figure 2 , Figure 2 This is a schematic diagram illustrating an electronic paper display method 200 for use on a device V according to an embodiment of the present invention. The electronic paper display method 200 includes steps 210 to 230. The electronic paper display method 200 can... Figure 1 This is achieved through the electronic paper display system 100 shown or other similar configurations. The following refers to... Figure 1 The electronic paper display system 100 shown is illustrated as an example.

[0044] In step 210, an environmental image P of the environment in which the device V is located is first acquired by the image capturing device 120. The image capturing device 120 can be rotated to different orientations to capture the surrounding environment of the device V, thereby obtaining one or more environmental images P adjacent to the electronic paper display panel 110 on the device V.

[0045] In step 220, the artificial intelligence model trained by the color recognition algorithm identifies the environmental image P to generate a control signal for the environmental color of the environment in which the corresponding device V is located. Specifically, training the artificial intelligence model by the color recognition algorithm also includes collecting several environmental images as a dataset, and finally generating an artificial intelligence model that can identify the environmental color based on the environmental image P.

[0046] In step 230, the processor 130 transmits a control signal to the electronic paper display panel 110, and then changes the color displayed on the electronic paper display panel 110 to be similar to the ambient color according to the control signal. Specifically, a driving circuit is also included between the processor 130 and the electronic paper display panel 110. The processor 130 first transmits the control signal to the driving circuit, and then the driving circuit generates a corresponding driving signal. Afterwards, the driving circuit drives one or more display areas of the electronic paper display panel 110 to emit the corresponding color according to this driving signal. In this way, the device V can be concealed in the environment to the greatest extent possible, making it difficult to be detected.

[0047] According to the electronic paper display system and method for device surfaces of the present invention, by using an electronic paper display panel coated on a carrier and a color recognition algorithm, the color of the carrier can be automatically adjusted according to the ambient color, thereby achieving a good stealth effect. In summary, the present invention can improve the environmental adaptability and survivability of devices and carriers, and reduce the risk of being detected or attacked.

[0048] Although the present invention has been disclosed above with various embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
