With the improvement in living standards over the past two years, more people are purchasing larger TVs. From the widespread sales of 55-inch TVs a couple of years ago to the recent surge in demand for 65-inch and larger models, it's clear that consumers are craving bigger and better viewing experiences. However, the size and price of mainstream LCD TVs have been rising rapidly, making them less accessible for many.
In the ultra-large TV market, LCD or LED models are not only bulky but also come with steep price tags. For instance, Sony’s 100-inch LCD TV costs around 500,000 yuan, while LG’s latest 77-inch OLED TV is priced near 200,000 yuan. As a result, projection technology has emerged as a more affordable alternative for large-screen displays. In the last two years, major manufacturers have started introducing laser projectors, signaling a shift in the industry.
What exactly marks the rise of laser television as the fourth generation of TV technology?
Laser projection TVs are still a relatively new concept for many. To clarify, they are a type of projection device that uses ultra-short focus and laser light source technology to create large images from a short distance. This innovation follows the evolution of television from black-and-white, to color, and then to high-definition. Laser TVs are considered a breakthrough in the fourth generation of TV technology because they can display images of 100 inches or even larger without needing much space.
One key advantage of laser TVs is that they are easier on the eyes during long viewing sessions. Unlike LCD TVs, which emit more radiation and consume more power, laser TVs operate using diffuse reflection, making them more comfortable for extended use. This makes them an ideal choice for families who watch TV for long periods.
Another benefit is their stability. Traditional projectors often suffer from issues like brightness fading and color degradation over time, requiring costly bulb replacements. Laser light sources, on the other hand, maintain consistent performance over long periods, reducing maintenance and saving money in the long run.
Additionally, laser TVs offer clearer image quality. While they may look similar to LCD screens, the panels used in laser TVs are "cold screens" that don’t require power. They include a multilayer film that reduces light scattering, resulting in sharper and more vivid images.
Lastly, laser TVs are less likely to experience color fading over time. Unlike CRT TVs, which suffered from color degradation, or LED TVs, which often have lower color saturation, laser TVs maintain consistent and vibrant colors. This ensures a superior visual experience even after years of use.
