In 2017, the laser TV market experienced a significant boom. The term "laser TV" gained massive popularity, growing exponentially in public awareness. Leading traditional brands like Hisense and Changhong were at the forefront of promoting these innovative products, followed closely by internet giants such as Xiaomi and Kansang. Additionally, established projector manufacturers including BenQ and Nuts began investing substantial resources into exploring the laser TV market. Laser TVs are known for their large screen sizes, long lifespans, and superior color reproduction. However, today’s discussion isn’t about laser TVs themselves, but rather an often-overlooked yet crucial accessory: the anti-glare curtain.
Many consumers might wonder why there's so much emphasis placed on purchasing an anti-glare curtain when a simple white wall or sheet seems sufficient for watching movies. The answer lies in the technology and benefits these curtains provide.
Anti-glare curtains are specifically designed to enhance the viewing experience of laser TVs by reducing the impact of ambient light. These curtains typically feature a unique sawtooth optical structure where the black absorbing layer atop the structure blocks unwanted light, while the base incorporates a specialized paint coating to ensure the true colors of the projected image are accurately displayed, resulting in a vivid, high-contrast image. This design not only combats ambient light but also boosts contrast, offering a superior visual experience compared to a plain white wall.
The technical principle behind anti-glare curtains can be simplified as redirecting the light emanating from the laser TV toward the viewer’s eyes. Unlike a white wall, which diffuses light in all directions leading to a loss of brightness, the carefully crafted anti-glare curtain focuses the light directly towards the audience, increasing screen brightness and improving overall picture quality. These curtains can achieve their glare-resistant properties either through physical structures or optical coatings, depending on the specific design principles.
Hisense, one of the pioneers in the laser TV industry, offers laser TVs equipped with Fresnel optical screens. These screens, produced by Chengdu Feisite Technology, are renowned for their exceptional optical performance, boasting a gain of 1.2, which represents a high standard within the industry. Hisense’s Fresnel screens are designed with a hard-metal frame, ensuring resistance to ambient light interference, thus maintaining excellent viewing quality even in well-lit environments. With a thickness of just 10 millimeters and no requirement for external power, these screens are perfect for integration into living rooms.
Changhong also equips its laser TVs with Fresnel optical screens, which similarly provide effective anti-glare capabilities. These screens reflect the laser light source into parallel beams, enhancing both brightness and contrast, resulting in clearer and more vibrant images.
Interestingly, not all laser TVs come with anti-glare curtains. For instance, Mijia’s laser TV, priced at $9,999, did not include an anti-glare curtain upon release. Meanwhile, Zimi’s T1 laser TV, priced at $79,999, came with a standard 100-inch anti-glare curtain, valued at approximately $5,000. This highlights the significant price difference between standard and premium anti-glare curtains.
In conclusion, anti-glare curtains remain a critical component for optimizing the laser TV viewing experience. Their advanced designs, combining physical structures or optical coatings, require extensive research and development. Currently, the domestic market lacks affordable counterfeit alternatives, as these imitations often fail to deliver the desired performance. Therefore, it is advisable for consumers to purchase laser TVs with factory-supplied anti-glare curtains rather than attempting to buy them separately.
