DESC:FIELD OF THE INVENTION
[0001] The present disclosure relates to programmable LED display system for military vehicles. More particularly, the present invention provides a programmable LED display system for dynamically displaying identification information on military vehicles.
BACKGROUND OF THE INVENTION
[0002] Military vehicles often require clear and visible identification markings for operational purposes. Traditionally, these markings have been implemented using static methods such as painted stencils, reflective decals, or fixed metal plates displaying vehicle numbers or tactical codes. While these conventional approaches have been widely used, they present certain limitations in dynamic battlefield environments.
[0003] Visibility of traditional markings can be compromised under various conditions, including low light, adverse weather, or when obscured by dirt or debris. This reduced visibility may hinder quick and accurate identification of friendly forces, potentially impacting tactical coordination and situational awareness during operations.
[0004] Furthermore, static identification systems lack the flexibility to adapt to changing mission requirements. In scenarios where operational security demands rapid changes to vehicle identifiers, the process of physically altering or replacing fixed markings can be time-consuming and resource-intensive.
[0005] The advent of light-emitting diode (LED) technology has opened new possibilities for display systems across various applications. LEDs offer advantages such as high brightness, energy efficiency, and the ability to dynamically change displayed information. While LED displays have found widespread use in commercial and civilian contexts, their application in military vehicle identification systems presents unique challenges.
[0006] Military vehicles operate in harsh environments characterized by extreme temperatures, shock, vibration, and electromagnetic interference. Any identification system deployed on such platforms must be robust enough to withstand these conditions while maintaining reliable performance. Additionally, military-grade systems often require specialized features such as night vision compatibility and low observable modes to support diverse operational requirements.
[0007] As armed forces continue to modernize their equipment and tactics, there is an increasing focus on enhancing battlefield networking and information sharing capabilities. This trend underscores the potential value of adaptable, electronically controlled identification systems that can integrate with broader command and control networks.
[0008] The prior art patent application US20180286247A1 relates to a vehicle identification system using LED displays. This system incorporates LED panels mounted on vehicles to display dynamic information such as vehicle identification numbers, status indicators, or other relevant data. The LED displays are designed to be visible under various lighting conditions and can be electronically updated to reflect changes in vehicle status or mission requirements. The system include features such as wireless connectivity for remote updates, integration with existing vehicle electrical systems, and ruggedized construction to withstand automotive environments. The displays may be configured to show alphanumeric characters, symbols, or simple graphics, allowing for versatile information presentation. However, the system may not incorporate advanced features such as night vision compatibility, low observable modes, or resistance to extreme environmental conditions and electromagnetic interference that are often critical in military contexts.
[0009] Therefore, in view of above mentioned drawbacks, there is a requirement of programmable LED display system for military vehicles that provides improved visibility in various environmental conditions, including low light and adverse weather, which can enhance situational awareness for both friendly and allied forces.

This may include the use of specialized LED arrangements or micro-lens arrays to ensure that vehicle identification information remains legible even when viewed from sharp angles or during vehicle movement.
[0053] The system (200) may also be designed to operate effectively in extreme temperature ranges typical of military deployments, from arctic to desert environments. This may involve the use of specialized components rated for wide temperature ranges and the implementation of active or passive thermal management techniques to maintain optimal operating conditions.
[0054] To support interoperability with allied forces, the display system (200) may be capable of switching between different identification formats or symbologies as required by multinational operations. This flexibility may extend to supporting various character sets or custom symbols specific to different military organizations or mission types.
