<br> <br> DLP technology is an innovative, uses optical semiconductor produces digital multi light display solution. It is the very high reliability for all digital display technology, in all kinds of products (such as large-screen digital TV, corporate / .family / professional Conference projector and digital camera (DLPCinema)) provides the best image effects. At the same time, this solution is a global electronics companies are fully mature independent technology. Since 1996, has provided more than 75 manufacturers supply is 500 million sets .of system. <br> <br> DLP technology has been widely used to meet a variety of pursuing excellence in Visual images. It is also the market of multi-function display technology. It is the only one that can also support the world's smallest .projector (below 2-lbs) and the largest of the movie screen (up to 75 feet) display technology. This technology enables the image is very high fidelity, gives a clear, bright, crisp picture. <br> <br> How DLP .technology <br> <br> This technology development through microelectronics engineering to achieve optimum picture quality the whole process of commercialization. <br> <br> 1. semiconductor technology has changed the world <br> <br> Each of the DLP ® projection .system is the core optical semiconductors, digital microscope device or DLP chip, this is a Texas Instruments' Dr. LarryHornbeck invented in 1987. DLP chip may be what date are the world's most advanced optical switching devices, containing 200 000 rules arrange mutually articulated mini .microscope. The size of each microscope is equivalent to one-fifth of the hair. When the DLP chip and digital video or image signals, lighting and projection lens co-ordination, microscopy digital image can be projected onto a screen or other surface. We .will DLP and advanced electronic devices called peripherals DigitalLightProcessin technology (optical data processing). <br> <br> 2. digital optical processing I: <br> <br> Grayscale image to DLP chip microscope, miniature chain fixed along the DLP Projection System .light forward (ON) or backward (OFF), formed on the projection surface or bright or dark pixels. Enter semiconductor device image bit stream code control microscope on or off, switching times per second, up to several thousand times. When the microscope is .frequently connected to off, the lens reflex light gray pixels are normally closed status of microscope reflected heavy gray pixels. In this way, DLP Projection System microscope could be reflected 1,024 pixels in shades of gray, will enter the DLP chip video or image signal is .converted to grayscale image rich layers. <br> <br> 3. digital optical treatment II: <br> <br> Add color DLT projection system lighting produces white light passes through the color wheel to DLP ® chip plane. Wheel optical filter for .red, green and blue. Single-chip DLP projection systems use the color wheel filtered light at least can generate .7 million colors. Take 3 tablets DLPCinema projection system can generate color not less than 3 500 million. Each microscope is on or off with three .basic colors. For example, to join the purple pixels of microscope is responsible only for the projection surface reflection red Blu-ray; visible to the people of these two fast flashing light, the projection of images on the mixture of colors. <br> .<br> 4. the application and configuration <br> <br> ★. Single-chip DLP Projection System <br> <br> Using DLP technology TV, home theater and business projectors mainly as a single chip DLP chip has been configured, .the described earlier. The white light produced by color wheel filters for red, green, blue, order to DMD surface. Microscope switch and "on" or "off" time, according to the projection of the color brightness tuning. One of the Visual .organ and the colour of the continuous casting, so they can see the full color image. <br> <br> ★ .3 chip DLP Projection System <br> <br> DLP technology-projector suitable for picture quality, or brightness, the .most demanding of situations, such as the cinema, or adopt 3-DMD-chip configuration system shows dynamic and static quality picture of a large Conference Hall. In 3 chip systems, lighting produces white light through a Prism divided into red, green and blue .light. Each chip DLP? one color for which, the microscope optical reflection of color through the combination of image formation through the projection lens. <br> <br> The advantages of DLP technology <br> <br> Beautiful picture <br> .<br> Clarity <br> <br> DLP & reg; technology generates the accuracy of the original data mirroring better than other display system. This is the DLP technology projection image always maintain the level of crystal clear. <br> <br .> DLP & reg; technology is the core of the lens by tens of thousands of digital microscope system consisting of the distance between each lens for less than 1 micron, so you can achieve very high duty factor. Minimizing the distance between the projected image .pixels, you can generate seamless digital pictures, in any size can maintain good sharpness, no other technology pixel mark or "sieve". <br> <br> Brightness <br> <br> Due to the lens, improves efficiency, lumen DLP .& reg; projection systems than all other display system is more brightness. <br> <br> With all other technical, light during the transfer process will be subject to certain losses, DLP projection system for the microscope illumination light source can be a .greater amount of light transmitted to the screen. <br> <br> They have the obvious disparity. DLP & reg; technology, home video entertainment products can produce enough to stunning visual enjoyment. Business communication can demonstrate a clear image, and with .or without lighting. Large venue show15, 000 lumens of bright enough to meet the requirements of a large number of viewers watching. <br> <br> Color <br> <br> DLP & reg; technical richness of color range can restore .350 trillion kinds of pigment. <br> <br> TV and home theater system, and all other technology, DLP projection technology gives rich black levels and shadow effects. Show film, DLPCinema? technology can restore 350 trillion kinds of pigment, eight times .more than the movie. <br> <br> Ingenious product specifications <br> <br> Design <br> <br> DLP & reg; technology is the core digital microscope devices, optical signal modulation is much faster than all other display .devices much faster. This means that the DLP & reg; projection system only requires a Panel, and all other technology you need three pieces. <br> <br> As a result, the projection subsystem can be very small, the weight is .light, leaving for the creative design adequate space. Product designers can conceive of small volume, light weight, more fashionable product. <br> <br> Ultra large-screen TV in the living room space can be saved. Portable projector weight can be .designed as two pounds, the brightness is available for viewing session presentations. <br> <br> Reliability <br> <br> DLP & reg; technology enables projectors, home theater systems and TV's performance is more stable and reliable <br> .<br> DLP & reg; technology of digital features product heat, not affected by humidity or vibration and other environmental factors, the image will not fade device long-term use. <br> <br> Each use & reg;, .DLP projection system can display the original source flavor picture, without tuning, maintenance is minimal.
