The concept of "smart micro-projection" is no longer unfamiliar to consumers. Compared to traditional display devices like TVs and smartphones, it offers a natural advantage in terms of portability, screen-free viewing, and large-screen experience. Since 2015, when LED-based smart micro-projectors broke through the 1000-lumen brightness threshold, the market has seen explosive growth. In recent years, analysts predict that the home smart micro-projection market will reach a scale of 10 billion yuan in the near future. Over the past three years, both traditional appliance manufacturers and emerging projector brands have entered the smart micro-projection space, drawing significant investment. Many people are optimistic about the future of projection technology, even surpassing smartphones and televisions in popularity.
However, despite the apparent enthusiasm, the smart micro-projection industry has gradually found itself in an awkward position. According to authoritative media reports, from January to July 2017, only 530,000 projectors were shipped online, with 430,000 units for home use and 1.9 million units for smart micro-projections (weighing less than 1 kg). With hundreds of millions of units sold, smart micro-projections accounted for less than one percent of the total. This highlights just how small the market truly is.
In essence, the limitations of display technology have prevented smart micro-projectors from significantly improving their resolution, which remains a key performance indicator. After years of development, most smart micro-projectors still operate at 720P or 800P resolution. In contrast, smart TVs and smartphones now commonly feature 2K or even 4K ultra-high-definition displays. The difference in image clarity is obvious, and many consumers remain hesitant, waiting for better options. Even the few 1080P models available often come with prices over 4,000 to 5,000 yuan, making them unaffordable for many. As a result, the prediction of a 10-billion-yuan market seems increasingly unrealistic.
Cool Music's R4 series recently launched, creating a buzz in the smart micro-projection market. What makes the R4 so popular? Let’s take a closer look at its impressive features.
Resolution:
Projector resolution refers to the physical resolution of the core light engine. Simply put, it determines how clear the image appears. Cool Music’s R4 features a full 1920×1080P physical resolution, offering 2.25 times the clarity of typical 720P smart projectors. This resolution is almost on par with high-definition LCD TVs.
Brightness:
Previously, smart projectors used RGB three-channel designs. The R4 uses an innovative RGGB four-channel design, boosting brightness by 30%. Combined with an 8A high-current LED light source and overcurrent drive technology, the brightness reaches 880 ANSI lumens—more than 1000 lumens, ensuring vivid visuals. Additionally, the LED light source lasts up to 20,000 hours, eliminating the need for frequent bulb replacements.
Glass Lens:
Many projectors use plastic lenses to cut costs, but this can lead to issues like blurring and defocus during playback. Cool Music’s R4 features a 7-spherical all-glass lens designed by optical expert Ma Yongzhen, along with precision-milled metal components. This setup effectively eliminates thermal defocus and other common problems.
Image Optimization:
Cool Music is known for its visual quality. The R4 includes 11 image optimization technologies, such as HDR high dynamic range, noise reduction, anti-mosquito noise, de-jittering, and color enhancement. These features significantly improve image realism, detail, and contrast.
Hardware Configuration:
The R4 uses a dual 64-bit Mstar processor with a Mali 3D GPU, delivering smooth 4K video decoding. It also features 3GB DDR4 + 16GB storage, twice the speed of DDR3, ensuring seamless performance without lag.
Speaker Sound:
Cool Music collaborated with AR, a renowned speaker manufacturer, to create a 10W two-channel discrete speaker system. Equipped with DSP sound field processing, DBE bass enhancement, and 360° Dolby surround sound, the R4 delivers powerful and immersive audio.
Additional Features:
The R4 also includes four-way trapezoidal correction, auto-focus, 3D active shutter display, and runs on the Light OS system for a smooth user experience.
Cost-Effective:
Launched in early December, the R4 series offered premium features at a price under 3,000 yuan, positioning it as one of the most cost-effective smart micro-projectors on the market. This helped boost the popularity of Full HD projections.
Currently, only the R4 and R4S models are available, but more models are expected in 2018. It looks like the trend is far from over.
