With the advancement of science and technology and the improvement of quality of life, home smart projectors have attracted more and more attention. For consumers who are keen to watch movies, pay attention to experience and emphasize atmosphere creation, home projectors are better than TVs in terms of aesthetics, practicality and comfort, and have gradually become the preferred device for viewing experience.
Vidda branded tri-color laser technology has become the industry benchmark for brightness and image quality. Over the years, Vidda has continued to innovate and launched a number of high-quality products to meet the needs of the market. In May this year, Vidda will release a new three-color laser projection product, once again injecting new vitality into the market.
Why is the tri-color laser the best light source technology?
Trichromatic laser technology emits light by using lasers (RGB) in three colors, red, green, and blue. Thanks to the laser's excellent monochromaticity, the red, green, and blue colors emitted are virtually free of stray light when the appropriate wavelength of the laser is selected. Subsequently, these red, green, and blue lasers are irradiated on the DMD chip, and finally the optical signal is integrated to form the desired color using the visual persistence phenomenon. Compared with conventional LED and monochrome lasers, trichromatic lasers have the advantages of high brightness, high contrast, wide color gamut, and healthy eye protection.
High brightness, high color gamut and high contrast: The three-color laser light source has higher brightness than the monochromatic laser, and the projection effect is better than that of the LED light source. It is also the only consumer display product that can exceed 100% of the color gamut BT2020, and the color gamut coverage can reach twice that of LEDs when converted to the same color gamut standard. In terms of contrast, the three-color laser picture is better than the monochrome laser, the contrast between light and dark is more in place, and the vision is more comfortable. Taking the Vidda series products as an example, its color gamut reaches 110% BT2020, the contrast ratio is as high as 1700:1, and many parameters are among the top in the industry.
Better eye protection, eye protection: In tri-color laser technology, blue light is generated by a separate laser emitter, so it is only necessary to avoid the harmful blue light spectrum and choose a blue light with a longer wavelength as the light source, such as the blue light spectrum in the 460nm band, to achieve a hardware-level anti-blue light effect. However, in monochromatic laser technology, the blue laser passes through the fluorescent color wheel to produce a variety of stray light, including short-wave blue light, which can cause great and irreversible damage to the eyes.
Dynamic speckle dissipation technology, non-inductive speckle to the naked eye: Speckle phenomenon is a "coherent" effect of light in the process of surface reflection with roughness greater than the wavelength of the light wave, which is a natural phenomenon and does not specifically refer to trichromatic lasers. This phenomenon is also common in daily life, so there is no basis for a direct correlation between speckle and tricolor lasers. At present, there are many ways to solve the speckle problem of three-color laser, such as Vidda adopts a new multi-dimensional dynamic speckle dissipation technology, which minimizes the "speckle" image interference caused by laser coherence, making the picture more transparent and clearer.
summary
The excellent performance of trichromatic laser technology is undoubted, and its high brightness, high color gamut, high contrast and eye protection characteristics have demonstrated excellent strength in various application scenarios. These significant advantages not only greatly improve the user's visual experience, but also meet the urgent demand of modern people for high-quality display technology.
With the stunning release of Vidda's new products in May, we have reason to believe that in the coming period, three-color laser technology will once again lead the market trend and set off a new upsurge, and its excellent performance and wide application prospects will promote the entire industry to new heights.
