On November 20th, Miji Technology, a leading domestic manufacturer of laser non-screen TVs, secured Baidu’s lead round C financing and became a major focus in the industry. Just three days later, on the 23rd, Hisense launched a range of 4K laser televisions, further boosting demand for laser TVs as a potential replacement for traditional LCD models. Laser TV, also known as a laser projector, is essentially a device that uses a laser light source combined with reflective ultra-short-focus projection technology. It consists of two main components: the projector and the projection screen. The term "television" is used because it employs a laser light source, which offers superior performance compared to conventional projectors, including features like anti-light curtains, ultra-short focus, and compatibility with standard TV cabinets.
However, due to high costs, laser TVs remain a niche product, mainly appealing to home theater enthusiasts rather than the general consumer market. Despite the buzz around their potential to replace LCDs, current laser TVs are still largely conceptual and experimental. They are not yet ready for mainstream adoption. The technology is still in its infancy, and while it has strengths in large-screen displays, it faces significant challenges in terms of cost, brightness, and color accuracy.
The industry is divided on whether laser TVs should be classified as projectors or actual televisions. In essence, a laser TV is just a projector with a laser light source and an anti-reflective screen, giving it a more TV-like appearance. However, without both the screen and the projector, it reverts to being just a projector. This makes the term "laser TV" somewhat misleading. The combination of these elements is what gives it the name, but it's not a true television in the traditional sense.
Laser TVs are designed as integrated systems that combine projection technology, anti-light screens, sound systems, and smart features. While they offer a unique solution, they are not simply cheaper alternatives to traditional TVs. In fact, achieving high brightness and color gamut comparable to LCDs often comes at a steep price. Consumers must pay for expensive anti-light curtains, which can cost several thousand or even tens of thousands of yuan. This pricing model limits their appeal to a broader audience.
Technically, laser TVs face challenges such as scanning deflection, where the laser beam scans the entire image line by line. This process requires high-speed rotation of components like prism wheels, leading to issues with noise, lubrication, and maintenance. These factors make it difficult to bring the technology to mass-market viability.
Additionally, many laser projectors lack smart features found in modern smart TVs, such as voice recognition and facial recognition. The resolution of most laser TVs is also a concern, with many claiming 4K capabilities but actually using 1080P lenses. Achieving true 4K would require advanced chips from manufacturers like Texas Instruments, which adds to the overall cost and complexity.
From a practical standpoint, the size of laser TVs presents another challenge. Most homes are not equipped to accommodate large screens, and the optimal viewing distance is often not met. A 150-inch TV, for example, requires a minimum of 3-5 meters of space, making it unsuitable for typical living rooms. Moreover, the human eye cannot fully appreciate the details of such a large display unless the viewer is very close, which may not always be feasible.
Brightness is another critical issue. While manufacturers claim high lumens, the actual brightness after accounting for ambient light and screen size is often much lower. This discrepancy leads to poor image quality, especially in well-lit environments. Anti-light screen technology helps, but it comes at the expense of reduced brightness, creating a trade-off between contrast and luminance.
Color accuracy is also a concern. Most laser TVs use a blue laser and a yellow fluorescent wheel to create white light, resulting in limited color gamut and potential color drift. True trichromatic lasers (red, green, blue) offer better color performance but are prohibitively expensive and complex to implement. As a result, most laser TVs today use two-color systems, which improve color quality but still fall short of true RGB performance.
Despite these challenges, some high-end models, such as Hisense’s T1, boast impressive specifications, including up to 4000 ANSI lumens of brightness. However, such models come with a hefty price tag, making them inaccessible to the average consumer. On the other hand, more affordable options like Miji’s laser TV at 9,999 yuan aim to disrupt the market, but they still struggle to gain widespread acceptance.
Overall, laser TVs are still in their early stages of development. While they have the potential to revolutionize home entertainment, they are not yet ready for mass adoption. For now, they remain a luxury product, suitable only for those with the space, budget, and technical understanding to appreciate their full potential. The future of laser TVs may lie in high-end homes or specialized settings, but for the average consumer, they are still more of a novelty than a practical alternative to traditional TVs.
