Today, when liquid crystal display (LCD) technology dominates the visual world, it is the hero behind the scenes – the backlight source that gives it a fresh life. When the traditional cold cathode fluorescent lamp (CCFL) gradually becomes history, LED backlight completely reshapes the display rules with its excellent performance. Understanding its precise working principle is the […]
For a long time, the lights in the operating room have been like silent dancers, and their projection direction and brightness determine the clarity of the surgeon’s vision. From flickering candlelight to dazzling halogen lamps, to efficient LEDs, surgical lighting has undergone a long evolution. However, the inherent limitations of overhead light sources – inevitable […]
Human-computer collaboration significantly improves medical efficiency and resource accessibility Telemedicine breaks the geographical cage: Video consultation and remote monitoring technology enable high-quality medical care to transcend mountain barriers. According to the World Health Organization report, telemedicine can increase the coverage of medical services in resource-poor areas by more than 30%, so that remote patients no longer lose […]
1.Material foundation: excellent performance of optical-grade transparent materials Light guide plate is by no means an ordinary transparent body. It requires the material to have extremely high light transmittance (usually >92%), low scattering rate and excellent mechanical stability. Polymethyl methacrylate (PMMA) and polycarbonate (PC) have become the mainstream. PMMA has a light transmittance of up […]
1. Light source revolution: Green transition from CCFL to LED The core power source of the backlight system has undergone a fundamental change. Although the early cold cathode fluorescent lamp (CCFL) had excellent brightness, its high energy consumption and large size have become a technical shackle. White light LEDs have completely reshaped industry standards with […]
1. The rise of multimodal interaction technology: a comprehensive upgrade from touch to brain-computer interface Traditional touch technology is still the mainstream of HMI (accounting for more than 60% of the global market), but the penetration rate of voice, gesture and brain-computer interface has increased significantly. In 2025, these three together account for 25% of […]
Abstract As a core component of modern display technology, light guide plate (LGP) converts line light source into uniform surface light source through precise optical design, and is widely used in LCD screens, advertising light boxes, medical equipment and intelligent lighting. Its core principle is based on the refraction, reflection and diffusion of light, combined […]
Abstract As the core optical component of liquid crystal displays, light guide plates achieve efficient light transmission and uniform distribution through precise optical control technology. This article systematically analyzes the working principle, material composition, functional characteristics and industry applications of light guide plates, and cites research data from international authoritative institutions to reveal how this […]
Introduction: The Medical Revolution from “Lighting the Outside” to “Lighting the Inside” In traditional operating rooms, surgeons often struggle with shadows, glare, and frequent lighting adjustments. According to statistics, the overhead light needs to be adjusted every 7.5 minutes on average (Journal of Surgery, 2022), and this inefficiency may even affect surgical accuracy. The birth […]
Introduction In the field of tactical equipment, fiber optic sights have attracted much attention as the “king of daytime”-the 2023 survey of the American Shooting Association showed that 78% of competitive shooters chose it as the main aiming device. However, the controversy over “whether it can emit light autonomously in the dark” continues to exist. […]
