Night vision system with transparent overlay display technology
The patent US12072506B2 describes a head-mounted night vision system that integrates a semiconductor chip designed to enhance night vision capabilities by superimposing a display image over an underlying image captured by a night vision device. The system features light emitters on the semiconductor chip that correspond to individual pixels of the display image, emitting light with intensity based on pixel values stored in a frame buffer. The processor within the system updates these pixel values at a slower frame rate than the rate at which they are communicated to the light emitters, allowing for efficient processing and display of information. Additionally, the system includes a communication interface for data exchange with an external controller, enabling the processor to receive and update pixel values based on various symbols and parameters.
Further enhancements to the system include the ability to detect the intensity of the first light using multiple detectors aligned with the display image pixels. This capability allows the processor to adjust pixel values based on the detected intensity, which can include information from infrared beacons or other light sources. The system can also transmit changed pixel values to an external controller, facilitating real-time updates. The integration of wireless communication and optical data reception further expands the system's functionality, making it adaptable for various applications, including the representation of alphanumeric characters, icons, and other symbols in low-light conditions. Overall, the patent outlines a sophisticated approach to improving night vision technology through advanced display and processing techniques.
