According to the specific analysis, due to the limitation of panel technology and comprehensive cost, the above-mentioned commercial LCD splicing large screen has been introduced. Each individual display liquid crystal unit can only reach 65 or 70 inches, so the liquid crystal splicing formed by the liquid crystal display unit is spliced. There must be physical seams on the large screen. Therefore, in the process of using the screen, the actual physical seams between the frame and the frame of each unit will inevitably lead to the splitting of the screen, which will hinder the viewing and damage the normal viewing effect. And this is exactly the opposite of current consumer demand.
For the small-pitch LED large screen, its self-illuminating technical characteristics make the picture have certain advantages in display brightness, picture saturation and contrast, but it is also due to its self-illuminating green laser pointer point light source technology. Long-term viewing of small-pitch LED large screens in the close-range indoors is very likely to cause blue light damage to the user's eyes. In the short term, it is easy for the human eye to accelerate fatigue, and in the long run, the eyesight will be degraded. In addition, a single LED small lamp bead constitutes a large LED screen. Since the attenuation curves between different lamp beads are inconsistent, after long-term use, the screen is prone to inconsistent color temperature or permanent damage of the lamp bead module, thereby increasing the maintenance cost in the later stage. These unfavorable factors will eventually lead to limited application of small-pitch LED large screens in indoor commercial displays.
The seamless laser large screen is based on the mature laser pointer projector in recent years as the light source core. The laser light source of the laser projector has the characteristics of large wavelength selectivity and high spectral brightness, which can synthesize the natural color of the human eye. More than 5% color gamut coverage for perfect color reproduction. At the same time, the laser source has an ultra-high brightness, soft and non-glare viewing experience, and its long service life greatly reduces the maintenance cost in the later period. In practical scenarios, these technical advantages are important guarantees for the massive data presentation and refined HD presentations in the era of big data and the Internet of Things.
Above, we can find that from the home laser TV, to the commercial seamless laser large screen, on the evolution of the product, home display and commercial display have chosen the development route of laser display technology. Therefore, we can roughly draw a judgment that in the home display field and indoor commercial display and other application scenarios, the laser large screen product is the best product with comprehensive performance and benefit ratio.
With the release of the "Made in China 2025" strategy, along with the maturity of the green laser pointer big screen technology, we have every reason to believe that in this round of large-screen industry upgrades, no matter in the home display field and indoor commercial display, the laser is big. Screen technology is the main route for the upgrade of the large-screen industry. Laser large-screen products will sing the protagonist in this round of industrial upgrading.
