Texas Instruments' "Ultimate Color Technology"
Projectors using single-chip DLP display technology have strong contrast, but far behind the 3LCD display technology in terms of color display, Texas Instruments (TI), which is the owner of DLP technology, has developed “extreme color technology†to make up for This deficiency.
In June 2005, Texas Instruments released "BrilliantColor", the official analysis of this technology is: based on the rich colors that the existing DLP technology can provide, this new color Processing enhancement technology can provide up to six colors of processing power at the same time, improving the color liveness of DLP projectors. This technology, which exceeds three color processing capabilities, can further enable DLP customers to deliver more stunning images and visual experiences. And, the extreme color technology uses a floating-point algorithm to ensure the accuracy of the calculation and reduce the noise. The increased computational accuracy and widened color gamut provide richer colors for DLP projection systems with extreme color technology.
One of the working principles of "ultra-color" technology is to increase lighting efficiency. For UHP bulbs, this technology can improve brightness by 50% over traditional tri-color solutions. At the same time this technique can be to broaden the color gamut and increase color saturation by improving the color wheel. The use of extreme color technology on the basis of traditional red, green and blue (RGB) color wheels can improve color processing and broaden the color gamut by utilizing intermediate colors.
The advantage of “extreme color†technology in image processing is that in addition to enhancing the optical efficiency of the DLP projection system, it further stimulates the color wheel's color performance. The "Ultimate Color" technology can be combined with different color wheel designs to achieve a wider color gamut in a DLP display system. The color wheel support multi-color processing is also very flexible, can be formed according to the needs of the 3, 4, 5, 6 color and other different color segment processing, so as to provide a very flexible color design space for projector equipment manufacturers , According to the different needs of users to produce a unique color gamut and brighter personalized products, differentiated competition in the market. It can be said that the projector using the "Ultimate Color" technology is excellent in terms of color brightness, color saturation, color gradation, and color accuracy.
Laser - very pure
In a laser beam, all photons are related to each other, that is, their frequencies (or wavelengths) are consistent, their phases are consistent, their polarization directions are consistent, and their directions of propagation are uniform. The laser is like a disciplined photon force, acting in unison, and therefore has a very strong fighting power. Many things can not be done by the general light source and the laser can do it.
The color of the laser is very pure. Although the monochromatic light source has a single wavelength, it still has a certain range of distribution. For example, the Xenon lamp emits only red light, and its monochromaticity is very good. It is regarded as the crown of monochromaticity. The wavelength distribution still has a range of 0.00001 nanometers. Therefore, the red light emitted by a xenon lamp still contains dozens of reds if it is carefully identified. . The light output from the laser has a very narrow range of wavelength distribution, so the color is very pure. Taking a He-Ne laser emitting red light as an example, the wavelength distribution of the light can be narrowed to 2×10^-9 nanometers, which is two-tenths of the wavelength range of the red light emitted by the xenon lamp. The monochromaticity of the laser far exceeds any monochromatic light source.
