The YANTOK YT-SG802D active shutter 3D glasses are professional 3D viewing accessories specifically designed for DLP-Link projectors. With precise synchronization technology, high-definition visual presentation, and comprehensive compatibility, they break through the limitations of traditional 3D glasses, bringing an immersive, high-definition 3D visual experience to home entertainment, business presentations, and cinema screenings. Balancing practicality and comfort, they are the preferred accessory for DLP-Link projector users, easily unlocking a new realm of 3D viewing. In terms of core working principle, the YT-SG802D adopts a core solution combining DLP-Link synchronization technology and active shutter imaging technology. It eliminates the need for an additional signal transmitter, significantly reducing usage costs and operational complexity. The principle involves using a DLP chip to add a white pulse synchronization signal between the left and right eye corresponding frames of an image. The photosensitive element at the front of the glasses captures this pulse and controls the liquid crystal light valves of the left and right lenses to alternately open and close, maintaining precise synchronization with the projector's image refresh. This rapid alternation allows the left and right eyes to see corresponding images respectively. Utilizing the persistence of vision, the images are then fused by the brain to form a realistic 3D image. It supports multiple frame rates of 96Hz, 100Hz, 120Hz, and 144Hz, adapting to the display needs of different DLP-Link projectors and avoiding ghosting and blurring issues, delivering a stable and clear 3D effect. The product has a wide range of applications, comprehensively covering various scenario needs. In home entertainment scenarios, it is compatible with mainstream DLP-Link projectors and laser TVs from brands such as BenQ, XGIMI, Xiaomi, and Dangbei. Whether watching 3D movies, playing 3D games, or watching 3D documentaries, it delivers a cinematic immersive experience, instantly transforming the living room into a private 3D theater to meet the leisure and entertainment needs of the whole family. In business office scenarios, it can be used with DLP-Link business projectors for 3D product model demonstrations, architectural design renderings, etc., making abstract design solutions more three-dimensional and intuitive, improving communication efficiency and presentation effects. In commercial cinemas and educational scenarios, it is compatible with professional DLP-Link projection equipment for 3D movie screenings, 3D teaching demonstrations, etc., balancing comfort and practicality, and adapting to the needs of long-term use. Compared with similar products, the YT-SG802D has four core advantages. First, it is fully compatible with all models, without distinguishing between projector brands and models. As long as the device uses DLP (DMD) technology and supports the DLP-LINK protocol, it can be seamlessly adapted with a 100% compatibility rate, far exceeding the industry average, completely solving the pain point of poor compatibility of traditional 3D glasses. Secondly, it offers high-definition, ghosting-free viewing. Utilizing high-transmittance LCD lenses with a transmittance of 38%±2% and a contrast ratio of 1000:1, it accurately reproduces image colors and details. Combined with a low-latency design, it effectively reduces eye fatigue, providing a ghosting-free and immersive viewing experience. Thirdly, it is comfortable and durable. Featuring a lightweight ergonomic design, the glasses weigh only 28g±3g. The frames conform to the contours of the face, and the ear loops are soft on the outside and firm on the inside, preventing constriction or pinching. Myopic users can easily stack them, ensuring comfortable wear for extended periods. The lenses are scratch-resistant, durable, and extend the product's lifespan. Fourthly, it boasts long battery life. Equipped with a built-in 80mAh rechargeable lithium polymer battery and a Mini USB charging port, it can operate continuously for approximately 40 hours on a full charge. With a standby current of less than 2uA, it automatically conserves power when not in use. An LED charging indicator clearly shows the charging status, eliminating the need for frequent charging and meeting the needs of extended use.
