Many laser TVs use three-color laser technology,At present, some smart projections have also begun to transition to this technology。 Many people say that the projection tricolor laser is the future light source, so what kind of technology is it?
Trichromatic laser technology is a technology that uses lasers to emit trichromatic light, namely red, green, and blue trichromatic lasers. This technology can be used in display devices such as projectors and laser TVs to achieve higher color expression and picture brightness. Compared with traditional LED technology, three-color laser technology has obvious advantages in color gamut and brightness, but it also has problems such as high cost and speckle.
The main advantages of tri-color laser technology are color expression and picture brightness. Since the laser light source is purer, the color gamut of the projection is higher. At the same time, the light brightness of the three-color laser technology is also higher, which can present a clearer and more delicate picture. These advantages make the three-color laser technology have high application value in the field of high-end display equipment.
However, there are also some drawbacks and challenges associated with tri-color laser technology. First of all, due to the limitations of laser luminous efficiency and high cost, the equipment price of trichromatic laser technology is relatively high, which limits its popularity in the market. Secondly, due to the luminescence characteristics of the laser, the three-color laser technology has the problem of speckle, that is, when viewed on a smooth plane, the picture will appear irregular bright spots.
However, in recent years, the industry has made great strides in solving the problem of speckle.
The main technology is to use a laser light source to generate a beam of high brightness and high contrast, and control the propagation of the beam through a microlens and an XPR chip. The XPR sensor recalculates the beam so that it forms a high-resolution image on the screen. This technique reduces beam scattering and speckle to provide a clearer, more detailed picture.
In addition, some brands also use special screen materials and optical path design to further reduce the effect of speckle. These screen materials and optical path designs can control the propagation and reflection of light, reducing the interference of speckle on the picture.
Therefore, speckle is no longer a particularly prominent problem, although it has not been completely overcome, but its impact on the general consumer has been relatively small. In addition, users can also adjust the color balance, contrast, brightness and other parameters of the picture to reduce the visual perception of speckle. Some brands have even achieved that the human eye is basically insensitive, so there is no need to worry too much about the problem of speckle.
When buying a tri-color laser projector, you can focus on the device with speckle reduction technology for a better visual experience. At the same time, with the development of laser projection technology, more advanced technologies may emerge in the future to help solve the speckle problem.
