Do not Buy a Projector If You Dont Have The Projector Knowledge.
Knowledge of the types of projector it is important to know before you buy a projector. Because this information will help you to obtain projector that suits your needs and budget you have. Well, there are three main types of video projectors namely CRT, LCD, and DLP. Although actually there are several other types such as LCOS, D-ILA and SXRD. This time we will review some of the common types circulating in the community. 1. CRT (Cathode Ray Tube) CRT projector in the form of a large projector device that consists of three lenses. Each of these lenses represent the basic colors. These three lenses combined with a magnifying lens that can project the image light colored to a large screen contained in a dark room. With the right blend of video circuits, the size of the CRT and lens combination, then a CRT projector can produce images with high resolution. CRT projectors have a number of advantages such as: • Image displayed in a CRT projector screened by using an electron beam and not limited to certain areas only. Therefore CRT projector be the best option when the resolution becomes a major consideration. • CRT projector is able to produce the blackest black color among all types of projectors. • CRT projector has a resistance to the projection of up to 20,000 hours. As a comparison, LCD projectors and DLP light source must be replaced every 1000 hours or 2000 hours to obtain a brightness or brightness and optimal contrast. Besides a number of advantages, CRT projectors also have a number of disadvantages, among others: • CRT projectors usually have a very large size. CRT projectors require a fairly extensive room as well as television measuring 20 ". Because the projector of this type is quite difficult to carry travel or move from one room to another. • CRT projectors do not have the capability to display images with great clarity as other types of projectors. Therefore this type of projector should be used in the room really dark. • CRT projector to be put together with the right to produce a high quality image. This is because the CRT projector has three lenses that must be aligned in order to project the image properly. If the lens fails to perform its functions, the two other lens also must be addressed to be able to reflect the colors and brightness are balanced. • CRT projectors usually have a higher price compared to other types of video projectors. 2. LCD (Liquid Crystal Display) projector type LCD produces light from a small three-panel LCD. LCD projectors have a larger size than the type of DLP projectors but smaller than the type CRT projector. LCD has several advantages for displaying video. These advantages include: • Front LCD projectors have a cheaper price. • LCD Rear Projector TV has the look thinner when compared to CRT Rear Projector TV because it has an LCD panel and a small lamp. This excess can certainly save space used to place the projector. • LCD projector has a brighter image due to the use of a separate light. For a more perfect and light, you should choose an LCD projector that uses LED backlight. Avoid having the projector with the lamp still traditional. • Although the LCD projector has three LCD panels, but this type has a light source so that users do not need to adjust the concentration of the image as it is done like on a CRT projector. Display LCD projectors are brighter so that it becomes more attractive. This projector display has the appearance of a higher quality than the display DPL projector. LCD and DLP technology offers distinct advantages. LCD projectors offer better color accuracy, while the DLP projector has a higher contrast ratio. 3. DLP (Digital Light Processing) DLP projectors usually have one chip with a small lens that can rotate. Light emitted by the chip and reflected through a wheel and then displayed on the screen. DLP projectors are smaller, lighter, cheaper and lighter when compared to LCD and CRT. But this type of projector has a contrast of colors and worse. Some advantages of DLP projectors make this projector is not only suitable for business but also for home theater purposes. The film will be digitally converted and stored on the hard drive or optical disc. Furthermore, the results of the conversion are included in the DLP projector and projected onto the screen. Another advantage possessed DLP projector is a good color accuracy, there is no effect of "screen door" that appears like the LCD projectors, require less power and has high contrast and brightness. Besides a number of advantages, DLP projectors also have a number of disadvantages, among others • As in LCD projectors, DLP chip has a certain number of pixels. • Although it did not produce the effect of "screen door" like the LCD projectors, DLP projectors produce an effect yet "rainbow". This effect displays a flash of colors when viewers see from the side. • As with the LCD projector, the light source must be replaced every 1000 hours or 2000 hours. Although the DLP projector technology is not perfect, but many home theater enthusiasts choose this type of projector. 4. LCoS (Liquid Crystal On Silicon) Many people are interested in having this projector because the projector technology is the result of a merger between LCD and DLP technology. LCoS is the best projector to produce a display image on the screen than any other projector. But this projector has the highest price when compared to other projectors on the market are common. 2.2. Resolution familiar with the projector Meanwhile, based on the resolution, the projector is equipped with some of the information that is SVGA, XGA, and SXGA +. This information is used to indicate the resolution used on devices with a standard screen 4: 3, such as computers and projectors. While WVGA, WXGA and WUXGA are used to mark the resolution contained in the devices widescreen 16: 9 as home cinema projector. Value resolution of a projector is measured in ANSI Lumens or usually called Lumens only. ANSI is an acronym for the American National Standards Institute. This shows the value ANSI format and method of measurement of light. While Lumens are a measure used to indicate the level of brightness or brightness of light projected. As an illustration, a paraffin wax to produce a level of resolution at 13 lumens, a 100-watt bulb produces 1200 Lumens. So the higher the value of lumens, the more real image produced in the same measure by a projector. When the size of the image is enlarged, the existing Lumens will spread on a larger area, thereby reducing the brightness of the image. The screen resolution standard 4: 3 • SVGA resolution of 800 x 600 • XGA resolution of 1024 x 768 • SXGA + has a resolution of 1400 x 1050 resolution widescreen 16: 9 • 480p (WVGA) has a resolution of 854 x 480 • 720p (WXGA) resolution 1280 x 720 • 1080p (WUXGA) has a resolution of 1920 x 1080 2.3. Key Issues in Choosing Projectors Well, when you intend to buy a projector, then there are many things to be considered. But basically there are three main things you should consider, namely the resolution, weight, and brightness. 1. Resolution The higher the resolution of a projector, the image is displayed even more perfect. Most projectors use technology SVGA or XGA. If you want to get a projector with a resolution better again, then of course you have to reach into deeper pockets. Technology SVGA 800x600 resolution suitable for displaying video, DVD, and some kind of a Powerpoint presentation. While technology XGA or WXGA has a higher resolution, which is 1024 X 768 and 1280 x 800. But of course the price is higher. Meanwhile, if you have enough money and need a projector with high resolution, so you can choose the technology SXGA with 1280 X 1024 resolution and UXGA technology that has a resolution of 1600 X 1200 resolution measurements equal to the measurement resolution projector monitors the PC (Personal Computer). The greater the resolution, the greater the size of the screen and the more that can be displayed. 2. Weight Usually projector weighs approximately between 2 Kg and 3.5 Kg. But there is also a projector that weighs less than 2 kg. Of course, this lightweight projector has a higher price. Projector that weighs between 2 Kg and 3.5 Kg features a more complete compared with a projector that weighs under 2 kg. Projector that weighs more than 3.5 kg are also available. Such projectors typically offer a number of advantages though quite troublesome if taken away. If you often travel with the projector, then choose a projector with a weight of 2 kg. 3. Brightness Brightness plays an important role in the use of a projector. A projector that has a high brightness capability will be very supportive if you want to display images in large sizes. In addition to the ability of brightness, intensity of light in a room also affects the image display projector. At a room with low light intensity, the projector lamp will be seen clearly. While in the room with high light intensity, the brightness projector capabilities will be very useful to display images perfectly. In addition to the intensity of light, medium for projection displays also have an influence. For example, a wall. Wall is bad media for projection displays because the walls do not reflect light very well. While the projector screen has the ability to reflect light well so as to display projection perfectly. Projectors usually have ANSI Lumens 2000-3000. Projectors less than 2000 ANSI Lumens will display the projections look bleak. While projectors over 3000 ANSI Lumens will display the projections very bright. 4. Contrast Ratio Contrast Ratio is useful to measure the darkest part and black, as well as the very bright and white colors projected. Contrast Ratio function estimating the level of light projectors for all types of room lighting conditions. The greater the lumens, the brighter the projected image. The more light a room, the higher the level required Lumens. 5. Features plug-and-play portable projector Most of today has been using a feature plug and play, easy to use and can be set appropriately. So, you only need electrical sockets only. You simply plug the cable in the electrical socket alone projector and the projector is ready to use. 6. Additional features Consider the special features that might meet your specific needs. Features that could be considered, among others: • Memory card, this tool can replace the role of the notebook for storing presentation materials. • Wireless or wireless, to simplify the user. • Ability networking, for the operation of any other place apart. • Digital keystone correction, to increase the flexibility of placement of the projector. • component video input, for better video quality. • Lens shift, which is more convenient to use.
