Projector technology types and specifications

Projector technology types and specifications

LCD Technical Specifications: LCD projector product structure, performance and cost requirements, LCD panels with different sizes. LCD liquid crystal panel size determines the size of the projector, the smaller the LCD liquid crystal panel Unit, the optical system of the projector can be made the smaller, so that the smaller the projector. But to achieve high resolution on a small LCD, and maintain a high brightness, and the difficulty of its technology can be imagined. 0.9-inch and 0.7-inch panel production, the ratio reached 70%, the proportion of 1.3 inches in about 15%, 0.5-inch, 0.79-inch, 0.99-inch and 1.0-inch panel for projector products. On the number of liquid crystal panel, since the monolithic structure in the aspects of performance and color defects is substantially eliminated. Mainstream 3-LCD projector, outstanding performance in terms of performance and color in a very long time, and represents the most mature level of projector product development. In the case of the same brightness and resolution, the the projector smaller the size the higher the price corresponding.
DLP Technical Specifications: LCD technology, the DMD chip size is an important factor to determine the size and weight of the projector, and Texas Instruments also introduced 0.55 inches, 0.7 inches, 0.9 inches and 1.1 inches of a variety of sizes chips. DLP projector, the most common structure of single-chip and three-two, three-structure theater systems and high-performance products are mainly used in the ordinary application of the common market, all the products are monolithic structure, people comparison of general talk about DLP technology and LCD technology, mainly based on the comparison between the single-chip DLP technology and 3-LCD technology. The single-chip DLP projector dichroic color wheel to achieve three primary colors with the same imaging components, compared with the three primary colors have imaging system 3 LCD projector, single-chip DLP projector in color saturation has been than three LCD projectors difference. The first generation of DLP projector color wheel speed of 60Hz, second-generation DLP color wheel speed doubled, still 120Hz to 120Hz, the next generation of DLP projector color wheel speed, but the color wheel with 6 separations (3 separations), equivalent to improve the speed and doubled, reached 240Hz. Current DLP projector color performance has been greatly improved, but compared to LCD products, the products of most of the single-chip DLP projector color performance is still lagging behind.

ANSI lumens
The main performance indicators of the projector, the unit of measurement for the brightness, the U.S. National Bureau of Standards lumens display device has a standard, this a standard measurement of brightness is usually ANSI Lumens. In general, the higher the lumens, the brighter the projector more upscale. The measurement screen brightness of the projected image: the image of one square meter were divided into nine in, measuring the value of each central point of light, and then calculated the average of nine.
CRT tube focus performance
CRT projector decomposition to the input source signal R (red), G (green), B (blue) under high pressure on the phosphor screen of three CRT tubes, light emitting, via a signal amplifier and a converging, shown on a large screen a color image. The focus of the CRT tube is divided into electrostatic focusing magnetic focusing and electromagnetic composite focus three, electromagnetic composite focusing more common, it is to focus performance, high focus accuracy can partition focus and corner focus, clear projection screen .
High pressure mercury lamp
A light source for generating a liquid crystal projector, the original lamp followed by a voltage, the high potential difference at the same time to generate heat, the mercury vaporized mercury vapor in a high potential difference, by the excitation discharge is generated between the pole pitch, the internal halogen element, there is the function of the catalytic and protection; its advantages as a light-emitting brightness, long life, LCD projectors currently on the market most of the ultra-high pressure mercury lamp.

Projector in the Top 10 Considerations

how to Use and maintenance of projection lamp

how to Use and maintenance of projection lamp


Bulb fear most often baking for a long time

Moment, the projector on the market from the first-tier manufacturers like Samsung, BenQ, Optoma code, according to the research reflect these brand projector both product workmanship, quality, after sales service, could make consumers satisfaction assured, so, in addition to individual cases, the projector automatically shuts down the culprit, we can exclude quality reasons.

Use, improper maintenance - According to a survey, in fact, cause the projector automatically shuts down or because of the temperature of the lamp, the heat not be able to shed caused when the projection lamp or the temperature inside the machine, projector hot protection function comes into play, along with the working status of the projector will automatically switch to the protection of state - the projector is automatically shut down, this time, you do not know what to do or worry about, first of all the measures taken after the projector automatically shut down after about half an hour, and then follow the normal boot sequence to turn on the projector, you can usually allow the projector to resume normal work.

In fact, solve the automatic shutdown cure a dustproof structure of the projector to be cleaned on a regular basis to ensure that the entire air duct patency maximize bulb cooling; Do not let the other is the projection bulb uninterrupted work long hours - I propose the user as much as possible not to allow the projector to continue to work more than 5 - 6 hours, even if the cooling fan, especially in the higher temperature environment can play a role in cooling, but still very long period of high temperature baking likely to cause the life of the attenuation of the light bulb, so, business education and home users, we must be reasonable arrangements for the time of the projected work. In addition, there is little need to explain general 200W bulb most reasonable continuous working time is 3 - 4 hours, beyond this time, we'd better let the projection halfway standby for an hour, until the lamp has cooled, and then to use.




Avoid direct unplug the power

Projector shutdown cooling fan will continue to rely on the power in the state of the high-speed operation over a period of time, the main purpose is to do so in order to let the bulb after prolonged use can be cooled to the lowest temperature, thus shortening when the fan stops working natural cooling time of the bulb, so when the user finished using the projector, it is recommended that until the fan stops working completely, unplug the power, so you can ensure the projection after each use, and can shorten the natural cooling with time, but also indirect from role to extend lamp life. Part of the special needs of that complete business people that go, the market has been that opened that off the projector with a small accumulators, can guarantee to cut off power supply fan can continue to work until the heat is dissipated, also can do the demo is complete you can cut off the power to the projector away.




Avoid repeated movement

In the projection process, we will certainly encounter To adjust the projector position, this time, a lot of people will be taken directly move to adjust to the appropriate placement. But here I want to warn that, in fact, the projection lamp when the temperature is very high, then the light bulb filament inside is usually semi-molten state at this time frequently moving the projector, it is likely The damage projection lamp. Therefore, I suggest, if it is placed in the projection, when we use two or three times the best can the projector be placed lock, such as a non-exceptional circumstances, we must avoid moving, so that not only each easy to use, and also reduce projection consequential damages.




Projector lamp replacement / installation method is very particular about the

When the projection lamp needs to be replaced, we should instantly view the projector enclosed instructions to ensure the maintenance and replacement steps correct; At the same time, the purchase of the lamp, we need to confirm what general types of bulbs can be compatible with the projector If you choose the wrong type of bulb, which are not compatible, and even may burn the projection lamp or projector.

Short so the Jingui the objects, we usually use the best be treated with caution, meticulously maintained, only one ultimate goal, to maximize the extended lamp life savings.

Take good care of your projector lamp

Take good care of your projector lamp

Light bulb is the main light source of the projector, it works very complicated, and will release a lot of heat during use, and each bulb is the high price. So, we are more of the Prevention of Cruelty to light bulbs. First thing to note the order of the switching machine, you should first turn the power switch, then hold the Lamp button on the projector panel, until the green light of the projector is stable; when the projector is turned off, you should always press Lamp button until the projector fan stops running , and then turn off the power switch. If not in the correct order, the projector lampmay not be a good heat dissipation, seriously will lead to unimaginable danger.

After you are finished using the projector, the user should turn off the projector control panel software switch, the light bulbs stop working, and then let the projector fan to continue working for some time, so the heat generated in the work cleared, the cooling fan stops working and then cut off power, which will also benefit on the bulb.
Then, we need to be careful not to frequent power to switch between the startup and shutdown state, the user should be maintained during the time for the heat about 5 minutes, this is due to supply part of the projector using a transformer and power switch tubes and other electronic components, these components in the process of frequent switching will produce great heat, causing the projector internal temperature is too high, causing the lamp to explode.
In addition, we also do not arbitrarily move the projector in the projection process, the inside of the bulb filament usually work in the semi-molten state, frequently moving the projector at this time is likely to damage the bulbs.
Finally, when you need to replace the lamp, we should look at the manual of the projector, ensure that the replacement of the correctness of the steps, make sure that what general types of bulbs can be compatible with the projector, be sure not to use is not compatible with the projector light bulbs, may cause the lamp working properly, or even damage.

How to choose the projector bulb

How to choose the projector bulb

In the projector bulb in use, to the life of the period must be replaced, some users think cheaper more affordable, and some users thought the bulb brightness is higher, the price more expensive. In fact, the correct choice must be from the projector type sets out, consider the use of the environment, it can be purchased to fit the projector bulb.
There are several major aspects:
1, do not have to buy the projector bulb manufacturers packaging. As everyone knows, the global projector light bulb manufacturers only PHILIPS ( UHP ), USHIO ( UMPRD ), OSRAM ( VIPR ), Panasonic ( MSCR ), EPSON ( UHE ), as well as several, projector manufacturers to these bulbs manufacturers orders, and their own production lamp rack and packaging box. The light bulb manufacturers produce only a light bulb, is not responsible for the lamp rack and packaging box.
2, prevent buy wick lamp. Now there are many unscrupulous traders use the purchaser’s ignorance sold for wick lamp to make profits, must be careful identification.
3, please be careful with the use of the original factory production UHP series of bulb. The projector bulb with the appearance of the original little difference, looks very beautiful. But as a result of technology and technical reasons, the light bulb three months later will decay quickly, life is authentic vendors bulb short. There are lots of unscrupulous traders take it as genuine sold for huge profits.
Non original bulbs as original bulbs:
1, light quality, easy explosion. Look from the exterior, the bulb lamp thinner, in the state of high temperature and high pressure is easy to damage. Despite the bulb photos plant manufacturers commitment to the warranty for six months, but to change the bulb to the normal work and study directly affected.
2, the bulb brightness is not enough. Practice has proved that, due to technical reasons, the brightness of light bulbs are not up to the standards. To estimate only the original 70% light bulbs, and after a period of time in use, brightness decay quickly.
3, the use of only half of the original light bulbs. In accordance with the use time to calculate, two non original bulbs corresponds to an original light bulbs, than to buy a original bulbs expensive.
4, the user does not understand the bulb, many unscrupulous traders take it as the original factory quality goods for sale. Now there are many kinds of false UHP bulb, a continental imitation UHP, its Cup appearance and McCoy are obviously different; and OSRAM company produced UHP, appearance and OSRAM out VIPR bulbs are very similar, but also in the wick has a filament around; there was UHP100W into 120W, 150W, 200W cup; and a wick ass is a filamentous guide electrode; there are now available do not know exactly how long lifetime of the Yellow cup. It is true and false matter, unless you are a light bulb professionals. These false UHP lamp with low cost, low price and the users don’t understand recognition at a low price to sell in the market, the original light bulbs are becoming less and less is more and more difficult to sell.
