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. […]
Introduction As global energy efficiency standards improve, the LED lighting market is expected to exceed $127.2 billion in 2028. Compared with traditional lighting, LED systems have become the first choice in commercial and industrial fields due to their advantages of 70% lower energy consumption and 5 times longer life. However, the performance of different types […]
Introduction of Light Therapy More than 130 million people suffer from chronic wounds every year, and the failure rate of traditional therapies is as high as 50% (World Health Organization, 2023). As a breakthrough technology, light therapy is subverting the field of wound care by precisely controlling wavelength and energy density. The latest clinical data […]
Introduction Light intensity is a fundamental aspect of both natural and artificial environments. It influences human health, plant growth, workplace efficiency, and even technological innovations. Properly measuring light intensity ensures optimal lighting conditions in various fields, from interior design and industrial safety to medical applications and renewable energy solutions. Despite its significance, many people overlook […]
