CVIA Lumen VS Ansi Lumen

2025-03-27

Why CRE Adopt CVIA Lumen Standard for Smart Home Projectors? As a leading provider of smart home projectors factory OEM more than 300 brands like Xiaomi/Anker/Dangbei/JMGO, we are committed to delivering the best visual experience for our customers. That’s why we have adopted the CVIA Lumen standard, ensuring more accurate brightness measurement and superior color consistency compared to traditional ANSI Lumens. Unlike ANSI Lumens, CVIA Lumens offer stricter regulations on color temperature (6000-18000K), uniform color space (CIE 1976), and color deviation (Duv ≤ 0.015), guaranteeing more precise and reliable brightness levels. Additionally, CVIA testing requires a 15-minute warm-up period before measurement, ensuring stable and consistent results. This means users enjoy a more immersive and true-to-life viewing experience at home. We believe this advanced standard will enhance your customers' satisfaction with brighter, more vivid projections. If you are interested, we would love to discuss how our projectors can benefit your business.

"Dust-free enclosed optical machine”

2024-12-12

The term “dust-free enclosed optical machine” generally refers to an optical equipment system that operates in an enclosed environment, especially where a high degree of cleanliness and precision optical operations are required. Such systems are often used in research, production and experimental applications where the optics are required to be kept free of dust and contamination to ensure precise operation and measurement. The following are some of the key features: Dust-free design: In order to prevent dust or other tiny particles from interfering with or affecting the optical system, the equipment is hermetically sealed. This design prevents dust from the external environment from entering the system and keeps the optics clean. Hermetically sealed construction: The system is completely enclosed to avoid contamination from outside air circulation. The air inside the optical system is made to a high standard of cleanliness by means of special materials or structures that meet specific environmental criteria. Optical system: Optical components contained within the system, such as lenses, lasers, optical fibers, etc., must be kept clean because any stains, dust, oil, etc., will affect their performance, leading to measurement errors or affecting optical performance. Application Scenario: This type of optical machine is widely used in semiconductor manufacturing, precision laser processing, scientific research experiments and other places that require an extremely clean environment. In these settings, any minor contamination may adversely affect the production process or research results. Translated with DeepL.com (free version)

About LCD sealed projector

2024-11-29

Looking for crystal-clear image quality without the hassle of frequent maintenance? Then you need to discover the LCD sealed projector! Compared to traditional open-frame LCD and DLP projectors, the LCD sealed projector excels with its outstanding color performance and unique dust-proof design. Why Choose an LCD Sealed Projector? First, the dust-proof design of the LCD sealed projector effectively prevents dust from entering the optical core, ensuring stable and clear image quality. Many users face a common issue: over time, their projector’s image gets blurry or colors start to fade. The sealed LCD projector solves this problem perfectly, allowing you to enjoy consistently high-definition visuals. Second, the LCD sealed projector excels in color performance, delivering natural, vibrant colors ideal for home theaters and business presentations. Unlike the potential “rainbow effect” found in some DLP projectors, the LCD sealed projector provides a smoother viewing experience, capturing every detail and bringing each frame to life. Finally, its low maintenance cost is a major advantage. The sealed design significantly reduces the risk of dust buildup inside the device, reducing the need for frequent cleaning and repairs—saving you time and hassle. Whether you're a home user looking for a flawless viewing experience or a business professional needing reliable visual quality, the LCD sealed projector meets your needs. High-definition image quality, natural colors, and low maintenance—it's the ideal choice for you!

A Smart Choice for Image Quality Preservation — LCD Sealed Projector

2024-11-05

A Smart Choice for Image Quality Preservation — LCD Sealed Projector In the projector market, the LCD sealed projector stands out for its superior dust-proof design and stable image quality. Compared to open-frame LCD projectors and DLP (Digital Light Processing) projectors, the LCD sealed projector is ideal for users seeking high-quality visuals, low maintenance, and longevity. Let’s take a closer look at the advantages of LCD sealed projectors and why they make a great choice for home entertainment and business presentations. LCD Sealed Projector vs. Open-Frame LCD Projector LCD projectors are known for their vivid image quality, but they come in sealed and open-frame designs. The sealed LCD projector is specially designed to prevent dust, with the optical system and LCD panel enclosed in a separate chamber that keeps out dust and other particles, ensuring consistent image clarity. Open-frame LCD projectors, however, expose the LCD panel to the air, which is more budget-friendly but can be affected by dust, leading to image blurring or color distortion. Stable Image Quality: The sealed design of the LCD projector prevents dust from entering the optical module, keeping color accuracy and clarity intact. This makes it ideal for long-term use without frequent cleaning and maintenance. Low Maintenance Costs: Due to the sealed structure, the impact of dust on the LCD panel is greatly reduced, lowering the frequency of component cleaning and replacement, which in turn reduces daily maintenance costs. This low-maintenance feature is particularly advantageous for home theaters and educational institutions where projectors are frequently used. Extended Device Lifespan: The sealed design can effectively extend the lifespan of the LCD panel. Even in dustier environments, the LCD sealed projector can consistently deliver excellent imaging quality. In comparison, open-frame LCD projectors are more suitable for users on a budget or those who don’t require extensive, long-term usage.
