When choosing a projector, the light source is the most important factor affecting the quality of projection. Currently, the main light sources used in the projector market are traditional light sources, LED light sources and laser light sources. Among them, laser light sources have advantages that traditional light sources and LED light sources do not have, such as high brightness, wide color gamut, long life, and low energy consumption. They have become the mainstream choice for flagship products. Currently, more than 80% of digital cinemas in the world use laser light sources. .
However, there are two types of laser projection. Many consumers only see "laser projection" marked on the promotional page, mistakenly believe that the effect is basically the same and blindly place an order, but the actual experience is very different. The
monochromatic laser uses a single blue laser to excite the yellow and green phosphors on the fluorescent color wheel, and refracts the red, green, and blue light produced on the DMD chip through the prism, and finally combines it into the desired color. form a projected image.
And Hisense ’s full-color laser technology is the first display technology to use pure three-color laser as the light source. It uses red, green, and blue three-color (RGB) lasers to emit light separately. Since the laser is very monochromatic, as long as the laser of the appropriate wavelength is selected, it can ensure that the emitted red, green, and blue light is almost Stray light, red, green, and blue three-color lasers are then irradiated onto the DMD chip respectively, and finally the light is combined to form the required color using the phenomenon of persistence of vision.
What are the outstanding features of three-color laser projection in actual experience? Let’s take Vidda C1, which currently uses Hisense’s full-color laser technology, as an example.
The first thing is the image quality. Vidda C1 has a 4K resolution that is rare among similar products. The image quality is excellent, the measured brightness is high, and it is more resistant to ambient light and can perform well during the day.
In terms of color, Vidda C1, which uses Hisense full-color laser projection technology, eliminates the fluorescent color wheel component and directly uses red, green, and blue primary color lasers as light sources. The actual color gamut coverage reaches 202% BT.709, and the color accuracy value is Reaching △E≈0.9, it has a color performance of up to 1.07 billion. After testing, many authoritative media concluded that the image quality of Vidda C1 is far better than that of models in the same price range, reaching the ceiling of image quality within 10,000 yuan.
In terms of eye protection, many projectors currently promote low blue light, which sounds very healthy, but Vidda C1 is the only one that dares to say that it has zero harmful blue light . Since Hisense's full-color laser technology uses 465nm laser as the blue light source, it avoids the 400nm-450nm high-energy short-wave blue light that is harmful to human eyes, and truly achieves 0 harmful blue light. The difference between low blue light and 0 blue light is still very big. .
Hisense's full-color laser projection technology surpasses monochrome laser projection in terms of image quality, color and eye protection, not to mention how far ahead it is compared to traditional light sources and LED light sources. The performance of Vidda C1, which is currently equipped with Hisense's full-color laser technology, is not difficult to find in the actual measurement. It is not difficult to find the advancement of three-color laser. No wonder some people say that this is the next generation of display technology.
