Texas Instruments DLP is an all-digital display technology with extreme reliability that delivers the best picture quality for a wide range of products, including large-screen digital TVs, commercial, home and professional projectors, and DLP theaters. This market's most versatile display technology delivers the sharpest and brightest picture quality, creating the world's most illuminating projector with less than a pound of illuminance, illuminating a giant screen up to 75 feet. Since the beginning of 1996, Texas Instruments has supplied more than 15.5 million DLP subsystems to 75 of the world's top display product manufacturers. According to the latest information from the Pacific Media Association, DLP has more than 50% of the global front projection industry and successfully won the leading position in the front projection market.
DLP Technology Overview
DLP is a true all-digital reflective projection technology created by Texas Instruments based on its Digital Micromirror Device (DMD). DMD is made up of millions of microlenses with an area of ​​10.8x10.8 microns, which is smaller than the cross section of the hair. Each microlens can reflect light from two directions; when the digital signal is in the "ON" state The microlens will rotate to +12 degrees. If the digital signal is in the "OFF" state, the microlens will rotate to -12 degrees. The microlens forms a gray scale on the front and rear of the rapid rotation, and then with one or three DMD chips, you can get a vivid color display. A DLP projection system with a DMD chip is called a "single-chip DLP projection system". The color filtered by the color wheel can generate at least 16.7 million colors, while the 3-chip DLP Cinema projection system can generate 35 million. Kind of color. DLP is currently introducing the latest "Extreme Color" technology, which can even create more than 200 mega colors.
As an advanced digital technology, DLP features high definition, high reliability, high dust resistance, high contrast, high response speed, high portability, and high cost performance.
High definition: The core of DLP technology is a digital micro-display system consisting of tens of thousands of lenses. The distance between each lens is less than 1 micron, which can greatly reduce the distance between the pixels of the projected image and generate seamless. Digital images can maintain good sharpness in any size without the lattice (mosaic phenomenon) caused by other technologies, which is why the image projected by DLP technology always keeps crystal clear.
High reliability: DLP is a digital technology. The advantage of digital projection technology is that it can completely and faithfully reproduce images without being affected by factors such as temperature, humidity or vibration. DLP chips have a service life of more than 100,000 hours. Make sure the picture does not fade.
High dust resistance: For educational projectors that account for more than 45% of the domestic market share, one of the most critical additional features is dust protection. Projectors made with DLP technology can be designed with a fully enclosed optomechanical design. DLP chips and other components can be protected by dust. It is difficult for dust to reach the core of the optical path, ensuring that the image quality is not affected by dust and remains the same.
High contrast: The three-dimensionality of the image is crucial when watching a movie. Because the human visual organ relies on contrast values ​​to identify the edges of objects, images with high contrast values ​​look sharper. When the contrast is low, the dark part is blurred, and the image appears flat and lacks realism. For the text textbooks (PowerPoint, Excel, Word files) commonly used in teaching, the high original contrast value of DLP technology can clearly and sharply present text, which is unmatched by other techniques that emphasize dynamic contrast, because the text is presented. For content, the projector requires a high "raw" contrast.
High response speed: DLP technology has a fast switching speed of only a few microseconds, which is thousands of times faster than the liquid crystal panel in milliseconds. Because of this fast response speed, even high-speed motion images such as racing cars or balls do not appear to be smeared, showing the clearest and most realistic images.
High portability: Single-chip DLP projectors for the education, business, and consumer markets require only one panel, while all other projection technologies require three. Therefore, DLP's projection system can be made small and the weight is much lighter, leaving plenty of room for innovative design. At present, many manufacturers such as Samsung, Mitsubishi and Toshiba have launched DLP pocket projectors with less than one pound to open a new era of projector applications.
Cost-effective: Texas Instruments uses semiconductor process technology to produce DLP chips. The semiconductor process not only helps to significantly reduce panel size, but also provides significant price reduction, which in turn provides consumers with affordable, high-quality products.
DLP is widely used
LCD has been the leader in the projector market for several years, but the emergence of DLP has brought huge impact to the LCD camp. Although DLP technology has been used in the projector industry for only 13 years, it has experienced rapid development, creating a record of market share growth for 15 consecutive quarters. At present, the market share of DLP projectors reaches 50%, and it has achieved half of the global projector market. Texas Instruments has partnered with more than 75 projector manufacturers, including Toshiba, BenQ, Optoma, InFocus, Sharp, Changhong, Lenovo, etc., to provide consumers with high-quality, cost-effective projector products, showing high color Saturation, real, natural picture.

Manufacturers such as Mitsubishi and Samsung have launched DLP HD 3D TVs in the North American market and are widely acclaimed. At present, there are more than 60 DLP high-end TVs from 5 brands in the US market.
Texas Instruments DLP Cinema technology ensures flawless movie screens with DLP Cinema technology with superior digital images and standards. At the same time, Texas Instruments DLP and technology licensors, including Barco, Christie and NEC, have been working closely together to ensure the best performance and image quality, and to help film exhibitors, publishers reduce costs, and ultimately bring consumers A digital cinema experience with reasonable price and excellent picture quality. In March 2008, Texas Instruments' DLP Cinema Products Division announced that IMAX will use DLP Cinema Projection Solutions. Under the agreement, it is expected that from the middle of 2008, the IMAX digital projection system deployed in commercial cinemas worldwide will be equipped with DLP cinema projectors to create an unparalleled IMAX digital cinema viewing experience for fans. Up to now, the screens using DLP cinema technology worldwide have exceeded 6,000 blocks. More than 99% of digital cinemas worldwide use DLP cinema technology.
DLP leads the new development of projection technology
Since Texas Instruments first introduced the ultimate color technology in 2005, it has attracted widespread attention from the media and users. This new technology successfully breaks through the traditional concept of three primary color processing, using up to six color processing methods, adding yellow, cyan and magenta complementary colors on the basis of red, green and blue. The addition of complementary colors can increase the number of color ratios, greatly increase the richness of color, and create more than 200 trillion different colors, equivalent to three hundred times of high-end plasma TVs. At the same time, with complementary color matching, the film and the natural landscape image occupy more than 90% of the intermediate color (the middle color is the color in the image other than pure red, pure green, pure blue), can also get significant brightness and color Upgrade. Most of the colors surrounding everyday life are intermediate colors. Therefore, the improvement of the intermediate color by the six-color processing means that the color rendering is more accurate and closer to reality. In addition to improving optical utilization efficiency, increasing system brightness and color display range, Extreme Color Technology brings more convenience and flexibility to projector design, bringing unlimited possibilities for product diversification. Extreme color technology offers design flexibility that no other competitive technology can match, greatly enriching the projector market and giving users more choice. In 2007, more than 70 DLP projectors with the most extreme colors entered the market in the next few years. DLP's ultimate color technology will still be the absolute backing of DLP projectors in color performance, and will also lead the projector from the traditional three. Color processing has entered a new era of multi-color processing.
The raw contrast is the baseline contrast value displayed by the projector for various screens, which is more critical for presenting dark field images. With the rapid development of DLP technology, the original contrast of DLP projectors is also increasing. In September 2007, Texas Instruments' DLP Products Division announced the launch of the new chipset DarkChip 4, further strengthening DLP's leadership in image quality and contrast. This new chipset is based on different applications and can increase raw contrast by up to 30%. In 2008, many of the listed DLP projection products will use the new DarkChip4 chipset. The DarkChip 4 was originally designed to meet the high-brightness and high-contrast image quality requirements of the digital cinema industry. In the digital cinema industry, DLP Cinema pioneered the industry and is a recognized global market leader. The DarkChip 4 achieves higher contrast by enhancing the lithography of the micromirror design with other professional processing.
