    Dlp Technology In Projector Lamps “use Dlp Technology For A Better And Sharper Image”

    By Brian on Wednesday, February 22nd, 2012 | No Comments

    DLP technology has overcome the drawbacks of the traditional LCD technology used in projector lamps. The poor and blurred quality image produced by the LCD, paved way for the use of DLP technology. With the advent of this technology, the images obtained are sharper and clearer.

    The DLP projection system works on the basis of a DLP chip. These DLP chips are made up of many micro mirrors. These mirrors are in turn made up of aluminum for the purpose of reflecting light and form clear pictures. The micro mirrors are arranged in the form of a matrix and each mirror represents a pixel which refines the quality of images.

    The chip tilts itself towards or away from the projector, as directed by the image code that enters the semiconductor. As a result the color of the pixel is determined. When the chip is directed towards the projector lamps, a light grey pixel is reflected and a dark grey pixel is obtained when the chip is switched off.

    Another vital advantage of the DLP technology is the BrilliantColor Technology. The lamp generates white light, which is directed towards the chip. The chip in turn has filters on its surface which further separates the white light into a minimum of three colors; red, blue and green. 16.7 million colors can be produced by a single chip in a DLP projection system.

    With the micro mirrors on the chip and the BrilliantColor Technology, the DLP technology used in projector lamps provide quality image. A wide range of DLP projector lamps are available at BulbToGo.

    Inside Your LCD TV

    By Brian on Friday, February 17th, 2012 | No Comments

    In an LCD TV or “transmissive” display, a light source shines through a panel of liquid crystals in order to display an image.  A white diffusion panel behind the LCD redirects and scatters the light evenly to provide a more uniform image than most competing technologies.  

    The LCD face consists of two transparent layers which polarize a liquid crystal layer sandwiched in between.  The front layer of glass is etched with a grid pattern on the inside surface to form a template for the liquid crystals.  Liquid crystals are rod shaped molecules that bend light in response to an electric current; the crystals align so that no light can pass through.  Each crystal acts like a camera’s shutter, either blocking light or allowing it to pass through.  A pattern of transparent or dark crystals forms the image.  This same technology has been around for awhile, even in such unsophisticated items as digital watches.

    LCD TVs use an “active matrix” LCD; the most advanced type of LCD.  The active matrix design is based on TFT, or thin film transistors.  These are tiny switching transistors and capacitors that are arranged in a matrix on a glass substrate, they switch the LCD pixels on and off.  In a color TV’s LCD, each color pixel is created by three sub-pixels with red, green, and blue color filters.

    One of the biggest challenges for LCD TV manufacturers has been speeding up the pixel response time, (how fast an individual pixel’s color can change without blurring) so that fast moving images don’t exhibit motion lag or “ghosting”.  This is especially critical for larger-screen LCD TVs, or for LCD TVs on which much of the viewing will be HDTV, or DVD movies.  

    An important difference between LCD technology and Plasma is that an LCD screen doesn’t have a coating of phosphor dots; LCD TVs color is created through the use of filters.  This keeps image burn-in from being a problem— which is good news in-particular for people who might use a video gaming system or PC on their TV. Another benefit of owning an LCD TV is the energy efficiency of this technology.  LCD TVs typically consume 60% lees power than comparably sized tube-type, direct-view TVs.

    In most ways that really matter there isn’t much difference between LCD TVs and Plasma TVs.  Both of these highly popular types of flat panel TVs are thin enough to be placed virtually anywhere, and both produce images that are startlingly clear, sharp, and bright.  The most notable difference is screen size.  The majority of LCD TVs have a screen size measuring 30 inches and smaller.  Plasma TVs are, for the most part, uninhibited by measurement restrictions.

    Basically, LCD and Plasma TVs are different approaches to the same result because the both create superior images using radically different technology.

    LED TV Technology

    By Brian on Monday, January 2nd, 2012 | No Comments

    LED means Light-Emitting Diode and unlike such a large amount of people think, it’s not a brand new TV technology. It’s just a different way to light the LCD – Liquid crystal. A liquid crystal is really a glass that actually works by manipulating the capacity of their segments (pixels) by varying the electrical signal. Each segment (pixel) provides a shutter to manage the quantity of light being passed through. The essential distinction between an Television technology and an LED TV technology may be the supply of light that go through these pixels.

    Television Technology

    On Television displays, fluorescent lighting is accustomed to back-light screens. LCD TVs make use of a Cold-Cathode Flourescent Lamp (CCFL), that are lamps that may, and therefore are utilized by many people to light their homes. To back-light a television, a number of these lighting is horizontally laid over the back from the television. The sunshine is distributed evenly onto the glass panel with a plastic sheet put into front from the light but for the greater degree, creates a clear image in your screen. However, developing a true black picture is usually difficult using the LCD technology. The reason being to darken a screen the sunshine source should be blocked out, with LCD, the sunshine is continuously on. Manufacturers cope with this by preventing the sunshine source having a screen is darkened, however with most televisions, the sunshine bleeds through, hence never enables a true-black image.

    LED TV Technology

    LED TV technology however use tubes (LEDs) that are small compared to CCFL tube to create the sunshine. There’s two types of LED lighting – edge and direct mount.

    Edge lighting arranges the LEDs across the fringe of the tv panel. Due to the tubes being installed on the advantage from the television, the tv can be produced much thinner. The ultra thin TV sets displayed in shops make use of this kind of lighting technology. LED light is channelled behind the tv glass, using the light being spread evenly by guides.

    Direct lit LEDs are tubes placed behind the tv glass. The quantity of LEDs placed depends upon how big the tv with as much as 1500 LEDS. Just one LED could be accountable for illuminating 1400 pixels in your screen. The benefit of direct lit LEDs is when a place of the screen is dark, the LEDs could be switched off thereby helping the contrast. This is referred to as local dimming, which LCDs cannot perform.

    There’s two kinds of direct lit LEDs – White and RGB (red, green, blue). White LEDs act like CCFLs for the reason that they produce white light. RGB LEDs make use of the three colours, making the tv effective at a broader range colour.

    The debate which is much better from LCD and LED TV technology continues, and also the debate on which kind of LED tube is better is definitely an a great deal larger debate. Opinion, in this instance, greatly rules!
