Since entering the market, DLP technology has always been more powerful than the LCD camp in terms of propaganda and market effects, which is why DLP projectors can account for more than 40% of the global market share in three or four years. At the beginning of DLP technology entering the market in 2001, the LCD camp was indeed a big idea, and the threat of DLP was not felt. TI was active all over the world, and invited more and more manufacturers to form alliances, such as BENQ, OPTOMA, etc. Large manufacturers are very willing to promote DLP technology, and even some Japanese manufacturers mainly based on LCD technology have introduced the DLP product line. Even after the establishment of the 3LCD Alliance, it has not been able to weaken the influence of many DLPs. DLP can be today, really a little myth! !
The battle between LCD and DLP technology seems to have been cold for a while, but the author always believes that technology is the foundation of quality innovation. Many exaggerated behaviors based on market strategy let it put it down. Today, we should talk again. Talking about the fundamental problem of technology.
Also in 2005, there was a major technological innovation in the LCD and DLP camps in the technology sector. The biggest innovation in the LCD camp was the conversion of organic materials for the manufacture of panel diaphragms to inorganic materials, while the DLP camp developed an extreme color. Technology (BrilliantColor). The same is technological innovation, but the strength of DLP camp promotion is still stronger than LCD.
LCD technology innovation
The LCD camp uses Epson and Sony as examples. Both manufacturers have changed the organic materials used to make panel diaphragms to inorganic materials. Although it is such a small change, it brings about the improvement of LCD technology.
Sony's panel brand with new technology diaphragms is called "Bi:NA6". This panel with new technology has a contrast ratio of 5 times that of most of the front projection projectors currently produced by Sony. At 2000:1, the aperture ratio is increased by 10%, and the image quality it can provide is between Sony's ordinary projector and the high-end Qualia 004. On the other hand, the original organic film alignment film is used in the LCD panel. Generally, the light barrier performance is poor, the contrast and brightness are relatively low, and the lifetime is not too long, and the new inorganic film can increase the lifetime to about the original LCD film. 4 times. This new panel will start mass production in about a year.
Epson and the panel developed to the D5 generation. In fact, its technology enhancement core is similar to that of Sony. The organic materials of the panel alignment film are changed into inorganic materials. Epson crowns this new technology called “Crystal HD Fine†inorganic orientation technology ( Crystal Clear Fine). This technology not only ensures the bright image achieved by the previous D series products, but also further increases the aperture ratio, greatly improves the contrast ratio (increased by 4 to 5 times compared with the past), and improves the black reproduction ability (reproduction black) Black) reduces the uneven orientation, making the image more detailed and clearer. Projector products developed using "Crystal HD Fine" inorganic orientation technology enable people to enjoy more realistic and natural images. Seiko Epson collectively refers to this technology as "Crystal Clear Fine" technology, which means it can achieve high definition quality like crystal. Epson's new technology is suitable for 3LCD projectors, including digital projectors and home theaters, and will be gradually applied to HTPS after 2006.
DLP technology innovation
BrilliantColor is a major technological innovation of TI in the United States. The brand that first strongly supports and adopts this technology is Mitsubishi. Currently known models such as Mitsubishi 549 and Mitsubishi MD-7200X are used. This technology.
What is the ultimate color technology (BrilliantColor)?
Extreme color technology, simply a color processing enhancement technology, provides the processing power of up to six colors in the same time, under the vivid colors that the existing DLP® technology can provide. Increase the color vividness of the DLP projector to make the picture more harmonious, real, natural and perfect.
Advantage analysis of BrilliantColor?
1. Breaking through the limitations of color gamut
Most display devices used in the past used three primary colors: red, green, and blue. The combination of the three primary colors can display all the colors in the triangle enclosed by these three colors (see Figure 1). This limits the range of colors that can be displayed.
Bright yellows and cyan, which are common in nature, are hard to show. Currently, the color gamut of all consumer-grade display systems cannot balance color gamut and brightness. You can increase the gamut range by increasing the saturation of the three primary colors. The saturated primary color shifts the red, green, and blue points of the triangle closer to the edge of the visible spectrum, increasing coverage. However, since the saturated primary color is generally not bright, the use of a saturated primary color reduces the overall brightness of the white and saturated colors. If you add yellow, cyan, and magenta to your image, you can get darker red, green, and blue dots while maintaining white spot brightness.
The three primary color gamuts have been used quite successfully in CRT display technology. A similar approach was used in the first generation DLP display system, which decomposed the image into red, green and blue components and displayed on a digital micromirror chip (DMD).
The color gamut of the red, green, and blue displays is a triangular region, and the three vertices are determined by the chromaticity values ​​of the red, blue, and green filters, respectively. Any color that the system can display is a mixture of red, green and blue. Although this color space is sufficient for many applications, it does not perform bright yellow and cyan. This is because the bright yellows and cyans we often see in nature are beyond the scope of this triangle. Adding extra colors allows us to expand the triangle into a larger polygon, and the available colors increase. Figure 2 depicts the triangle of the Rec. 709 color standard used by many television sets today. By using multiple primary color wheel and extreme color technology, we can extend the color gamut to the outer polygon (dashed line).
This new color gamut represents the richer colors of nature than most of today's display systems. The new color gamut also better balances chromaticity and brightness, presenting the most realistic colors, giving viewers a wonderful visual experience.
