[0028] DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0029]

[0022] One skilled in the art will realize the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing embodiments are therefore to be considered in all respects illustrative rather than limiting of the invention described herein. Scope of the invention is thus indicated by the appended claims, rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

[0030]

[0023] Embodiments of the present invention are directed to a display system that works well in both day mode and night mode, for example, when the user (e.g., a pilot in a cockpit) wears NVG. Such a display system may include two displays attached to each other, the front display is operated during light hours in day mode and the back display is operated during darkness at night mode. The switching between day mode, and night mode may be manual (e.g., by the user) or automatic, based on signals from sensors, or external devices.

[0031]

[0024] The arrangement of a first display and a second display, where the first display comprises subpixels with transparent portions and the second display comprises subpixels that may include opaque portions, may allow for a dual-mode operation suitable for both day and night conditions. This configuration may ensure that the display system can switch between high-visibility day mode and NVG-compatible night mode without compromising image quality or requiring separate display units.

[0032]

[0025] By incorporating Micro-LEDs or O-LEDs in both the first and second displays, the system benefits from the superior image quality, higher brightness, and better efficiency of these technologies compared to traditional LCDs. This results in a display that is not only more energy-efficient but also provides sharper images with deeper blacks and a wider range of colors, enhancing the overall user experience.

[0033]

[0026] An additional benefit of Micro-LEDs or O-LEDs displays is that neither requires backlight. Backlight is a huge energy consumer, therefore, Micro-LEDs or O-LEDs displays have higher energy efficiency.

[0034]

[0027] The physical attachment of the second subpixels to the transparent portions of the first subpixels may ensure precise alignment, which is crucial for maintaining image integrity and reducing any potential misalignment issues that could degrade the display quality. This precise alignment is particularly important in applications where clarity and accuracy are critical, such as in aviation cockpits.

[0035]

[0028] The compatibility of at least one of the displays with NVIS or NVG ensures that the display system can be used effectively with night vision equipment, addressing a significant limitation of current LCD-based NVG-compatible displays. This compatibility is achieved either through the use of NVG-compatible transparent portions in the first display or by tuning or filtering the red subpixels of the second display to emit NVG- compatible colors such as orange or yellow, providing flexibility in design and implementation, as discussed and explained with respect to Fig. 6 herein below.

[0036]

[0029] Reference is now made to Fig. 1 which shows an exploded view of a compatible display according to some embodiments of the invention. A compatible display 50 may include: a first display 10 comprising one or more first subpixels 12, and a second display 20, attached to first display 10, and comprising one or more second subpixels 22. In some embodiments, each one of the first subpixels 12 and the second subpixels 22 may include Micro-Light Emitting Diodes (Micro-LEDs) or Organic LEDs (O-LEDs) 14, or 24.

[0037]

[0030] In some embodiments, first display 10 may be the front display, and the second display 20 is the back display.

[0038]

[0031] As used herein, an O-LED, refers to a display technology that uses organic materials to produce light. O-LED displays are made of thin layers of organic materials sandwiched between two electrodes. When an electric current is applied to the electrodes, the organic materials emit light. The color of the light emitted depends on the type of organic material used. O-LED displays are self-illuminating, which means that they do not require a backlight similar to Liquid Crystal Displays (LCD). This results in thinner, lighter, and more energy-efficient displays than LCD.

[0039]

[0032] As used herein, a Micro-LED, refers to a display technology that uses microscopic LEDs to create individual26s / sub-pixels on a screen. Micro-LEDs have many performance advantages over LCD and O-LED displays, including higher brightness, lower latency, higher contrast ratio, greater color saturation, intrinsic self-illumination, and better efficiency. The main advantages of Micro-LEDs, may include: (i) Superior Image Quality: Micro-LED promises incredibly sharp images with deep blacks, high brightness, and a wide range of colors. This is due to the fact that each micro-LED can be turned on or off independently, achieving perfect black levels and unmatched contrast; (ii) Durable and Long-lasting. Unlike O-LEDs that use organic materials, micro-LEDs are inorganic. This means they are less prone to bum-in (image retention) and offer a potentially longer lifespan; and (iii) Highly Efficient: Micro-LEDs are efficient at converting electricity into light, leading to potentially brighter displays while consuming less power.

[0033] Therefore, since both O-LEDs and Micro-LEDs are flexible and transparent, they may be suitable to be included in a compatible display according to embodiments of the invention. In some embodiments, at least one of, first display 10 or second display 20 is compatible to a Night Vision Imaging System (NVIS) or a Night Vision Goggles (NVG). The selection of the wavelength compatibility is discussed and explained with respect to Fig. 6 herein below.

[0040]

[0034] Micro-LEDs or O-LEDs displays may include a series of thin layers of materials, each serving a specific function in the emission of light. The primary structure includes a substrate, an anode, organic or inorganic emissive layers, and a cathode. The substrate, for example, made of glass or flexible plastic, provides the foundational support for the display. The anode may be composed of a transparent conductive material such as indium tin oxide (ITO), which facilitates the injection of positive charges (holes) into the emissive layer.

[0041]

[0035] The emissive layer in O-LEDs consists of organic compounds that emit light when an electric current passes through them. This layer is sandwiched between the anode and the cathode. In Micro-LEDs, the emissive layer comprises microscopic inorganic LEDs, each acting as an individual pixel or subpixel. These Micro-LEDs are directly deposited onto the substrate, allowing for precise control over light emission and color.

[0042]

[0036] The cathode, for example, made of a low-work function metal such as aluminum or calcium, injects electrons into the emissive layer. When an electric current is applied, electrons from the cathode and holes from the anode recombine in the emissive layer, resulting in the emission of light. The color of the emitted light depends on the specific materials used in the emissive layer. For O-LEDs, different organic compounds are used to produce red, green, and blue light. For Micro-LEDs, the color is determined by the semiconductor material, such as gallium nitride for blue and green LEDs, and aluminum indium gallium phosphide for red LEDs.

[0043]

[0037] In some embodiments, at least one first subpixel 12 of first display 10 may include one or more Micro-LEDs or O-LEDs 14 emitting at least one of, green, blue, and red light, and a transparent portion 16. A detailed illustration of two optional subpixels 12a and 12b is given in Figs. 2A, and 2B. Subpixel 12a may include 3 Micro-LEDs or O-LEDs 14 each emitting green, blue, and red light, and a transparent portion 16b covering the area of subpixel 12a not comprising Micro-LEDs or O-LEDs 14. Subpixel 12b may include a single Micro-LEDs or a single O-LED 14. As should be understood by the one skilled in the art, the green Micro-LEDs or O-LED shown in Fig. 2B is given as an example only, and subpixel 12b may include any one of green, blue, and red Micro-LEDs or O-LEDs 14.

[0044]

[0038] In some embodiments, transparent portion 16b may be compatible to NVIS or NVG. For example, the panel of the display may include, monolithic glass, polymers, or composites, that comply with MIL-STD-85762 and / or MIL-STD-3009 standards, as discussed with respect to Fig. 6.

[0045]

[0039] In some embodiments, compatible display 50 may further include driver circuits that control the current supplied to each subpixel or subpixel. These circuits may be integrated into the display's backplane, which can be made of silicon or other semiconductor materials. The driver circuits ensure that each subpixel receives the correct amount of current to produce the desired brightness and color. Additionally, power management circuits may regulate the overall power consumption of the display, enhancing energy efficiency and prolonging the lifespan of the display components.

[0046]

[0040] In some embodiments, at least one second subpixel 22 of second display 20 may include one or more Micro-LEDs or O-LEDs 24, and a portion 26. A detailed illustration of two optional second subpixels 22a and 22b is given in Figs. 2A, and 2B. Second subpixel 22a includes 3 Micro-LEDs or O-LEDs 24 / 24a, and a transparent portion 16a covering the area of subpixel 12a not comprising Micro-LEDs or O-LEDs 14. Second subpixel 22b includes a single Micro-LEDs or a single O-LED 24. As should be understood by the one skilled in the art, the green Micro-LEDs or O-LED shown in Fig. 2B is given as an example only.

[0047]

[0041] In some embodiments, when first display 10 is attached to second display 20, at least one Micro-LED or O-LED of second subpixel 22 is attached to transparent portion 16a of a corresponding first subpixel 12.

[0048]

[0042] In some embodiments, when transparent portion 16 of first display 10 is compatible to NVIS or NVG, each second subpixel 22 may include at least one Micro-LED or O-LED emitting at least one of, green, blue, and red light.

[0049]

[0043] In some embodiments, when transparent portion 16 of first display 10 in of regular transparency and not compatible to NVIS or NVG, each second subpixel may include at least one Micro-LED or O-LED emitting at least one of, green, blue (Micro-LED or O-LED 24), and NVIS or NVG compatible red light (Micro-LED or O-LED 24a). In some embodiments, the NVIS or NVG compatible red light is an orange light, or a yellow light , as discussed with respect to Fig. 6.

[0050]

[0044] In some embodiments, portion 26 not including the Micro-LEDs or O-LEDs may be an opaque portion, a semi-transparent portion, or of regular transparency. As used herein an opaque portion comprises a panel that is configured to block at least 70%, 80%, 90%, or more from the visible light.

[0051]

[0045] Referring again to Figs. 2A and 2B, show illustrations of subpixels according to some embodiments of the invention. In some embodiments, first display 10 may be attached to second display 20 such that each first subpixel 12 is substantially attached to a corresponding second subpixel 22 with a maximum offset x of 10% of the first and second subpixels' dimensions. For example, a lateral offset may be not more than 10% of the width of the subpixel, and a vertical offset may be not more than 10% of the height of the subpixel. In some embodiments, first subpixel 12 and second subpixel 22 may have substantially the same dimensions. In some embodiments, the maximum offset may be not more than 8%, not more than 6%, not more than 5%, not more than 4%, not more than 3%, not more than 2%, not more than 1%, not more than 0.1% or any value or range in between. In a nonlimiting example, a subpixel comprising O-EED has a size of 40 to 200pm, therefore, the maximum offset x may be between 4 to 20pm. In another example, a subpixel comprising Micro-EED has a size of 2.5 to 5pm, therefore, the maximum offset x may be between 0.25 to 0.5 pm.

[0052]

[0046] Reference is now made to Fig. 3 which is a block diagram of an article according to some embodiments of the invention. An article 100 may be a display system for displaying information both in day and night modes. Article 100 may include a compatible display 50 accoridng to any one of the embodiments disclosed herein above. Article 100 may further include a power source 30, for providing electrical power to a compatible display 50 and a controller or computing device 60. Controller or computing device 60 may be configured to execute the method discussed with respect to the flowchart of Fig. 4.

[0053]

[0047] Article 100 may further include two controllers 60, a first controller controls the first display and a second controller controls the second display. A nonlimiting example for controller 60 is given with respect to Fig. 5.

[0048] Article 100 may further include a switch 40, for example, a bezel switch, for manually selecting between day mode or night mode, meaning, selecting between the operation of first display 10 or second display 20.

[0054]

[0049] Switch 40 may be integrated into article 100 to facilitate the manual selection between day mode and night mode. Bezel switch 40 may be positioned on the outer frame of compatible display 50, allowing the user to easily access and operate the switch without obstructing the view of the display. Switch 40 may include a tactile button or a rotary dial, providing a clear and responsive interface for the user to toggle between modes.

[0055]

[0050] Upon activation, switch 40 may send a signal to controller 60, indicating the desired mode of operation.

[0056]

[0051] Switch 40 may also include an indicator light or display to provide visual feedback to the user, confirming the current mode of operation. This ensures that the user may quickly verify the mode without needing to look away from the primary display area.

[0057]

[0052] Reference is now made to Fig. 4 which is a flowchart of a method of controlling a compatible display according to some embodiments of the invention. Article 100 may be operated in two modes, a day mode, and a night mode. Therefore, in step 410, an indication for a day may be received. The indication may be received from a bezel switch operated manually by the user or automatically. For example, the day mode indication may be received from a light sensor, an information related to day hours at the specific date (in the annual calendar), stored for example, in storage system 6 of controller 60, from an external computing device (e.g., a main controller), and the like. In step 415, first display 10 may be operated, presenting information to the user using green, blue, and red subpixels.

[0058]

[0053] Alternatively, in step 420, an indication for night mode may be received. For example, the night mode indication may be received from a light sensor, an information related to day hours at the specific date, stored for example, in storage system 6 of controller 60, from an external computing device, and the like. In step 425, second display 20 may be operated. In one embodiment, if first transparent portion 16 is compatible to NVIS or NVG, the information may be presented using green, blue, and red subpixels. In another embodiment, if first transparent portion 16 is not compatible to NVIS or NVG, the information may be presented using green, blue, and NVIS or NVG compatible red (e.g., orange and yellow) subpixels.
