What Makes a Projector? -LCD

Last time we spoke I talked about what a DLP Video Projector is.  How it works as well as its Pros and Cons.  From this point forward, I will be discussing what makes another large segment of the projector market, LCD Projectors.

LCD (Liquid Crystal Display) is a subtraction display technology versus DLP, additive display technology.  DLP Adds layers of colors to make an image where as LCD blocks pixels to take away color for dark area.  One is not better than the other. One of the main advantages of LCD is the lack of a color wheel.  This means one of DLP's main detriments(rainbowing) is not a concern.  LCD uses 3 colored filters to break the light into Red, Green and Blue.  These are then re-combined before final projection.

LCD Projectors were the first projectors on the market.  They quickly replaced the older and antiquated CRT (cathode ray tube) Projectors.  Their portable size and surprisingly bright image( for the time) was a welcome change.
You would think this type of technology was rather new, but in reality its almost 35 years old.  The first 'Light Valve' was pioneered in 1968 at RCA by John van Raalte.  It took until 1984 for him to work out the issues such as being able to control the 'light valves' in a meaningful way for a projector.  Since each pixel is arranged in a grid pattern, there needs to be a way to address each pixel.  This also showed the first use of negating the 'screen door affect' of each pixel being too obvious and looking like a grid of color.

It wasn't until the mid to late 1990s that LCD computer projectors became more common place. Before then, the most common form of LCD projector was a flat panel that was set atop a common overhead projector.

Once the LCD digital projector became common place it rapidly advanced.  At first the contrast was an issue at low brightness's.  The implementation of an auto iris resolved that.  This Iris physically blocks the lamps light beam at a specific level to balance the light needed to display the color required by the video.

Both LCD and DLP Projectors use lamps and lenses. Everything in between is quite different.
The lamp in an LCD projector starts off by focusing its light through a lens in the front of the lamp. This lens ensures the maximum amount of light hits the first lens of the projector.  The lens ' job is to focus the lamp light onto the the next piece of glass which is a color prism.  This prism reduces the light to its core colors of Red, Green and Blue.  The now filtered light is passed through a set of mirrors and multiple Dichroic filters.

The 3 filters further filter the lights to single color channels. Each of the 3 core colors have their own light path and their own LCD panel. Directly prior to passing through the LCD panel the light is balanced by 2 polarized glass panels.  These are adjusted in the factory so that each color is of equal intensity. This is critical because once the light passes through the LCD panel it is now 1/3 of the picture.  It is combined with the other 2 colors to form the full color image.  If any of the 3 colors are more dim or bright than each other, the image will look out of balance and not vivid.
The Lamp in an LCD projector is different as well.  The lamps usually have an optical lens rather than a filter lens as in a DLP lamp.  There is no need to block the UV and IR as it leaved the lamp.  The UV is already blocked by the glass, but the IR is not going to affect a color wheel so it can be filtered out after it leaves the lamp.

At one point around 2010 DLP projectors were surpassing LCD in quality but now the differences can be minuscule in the image quality.  LCD is still quite popular and posses a slightly large part of the home theater market but only barely.

Either projector can serve you well for most purposes.  Once type of lamp is not necessarily more expensive either.  Ideally you want to look at the picture.

If the image looks how you want it to look then LCD is the right technology for your home theater.  Maybe DLP looks better since it does have slightly deeper colors?  At that point it is up to your personal preference.   Be sure to follow us for our next post where I will discuss the other types of display technology such as LCOS and DiLA.

No matter which you choose you can get your lamp from us with the confidence that you are purchasing from a company who knows lamps.

10 Tips to Prolong Lamp Life from Pureland Supply

Projector lamps are most important to your projector. Prolong their life with these tips.


1.  Handle the Projector Lamp with gloves. Oils and deposits from hands and fingers can cause hot spots on face of the Projector Lamp, which may result in premature Lamp failure.  Gloves also insure against any smudges that could get on the glass lenses or the projector or the lamp itself.

2.  Operate your projector in a clean, cool, and well ventilated area. A dust free environment would be ideal.  It may be advantageous to look into a ventilation system or air filtration system in the area that the projector will be operating in.

3.  Keep the projector air filters and air vents clean. Clogged filters/vents will not remove heat effectively. This can cause the projector to overheat with an early lamp failure.  During routine maintenance it is recommended to vacuum any loose debris and dust from the projector.  You can also get a can of sealed air to blast out any small particles and dust from the air vents and filter.

4.  Do not place anything on top of the projector or in front of the intake or exhaust vents. This will cause the projector lamp to overheat and fail. Refer to your manual for safe placement of the projector and the accessories.  The vents should be operating in an unrestricted environment that has strong air circulation.

5.  If the projector is built into a compartment, wall, ceiling, or shelf mount, the minimum distance requirement is usually at least 2 feet.  This allows enough space to dissipate any heat that will build up.  Refer to your owner’s manual for specific recommendations.

6.  When you replace the projector lamp make sure the new housing is seated completely and securely. Pureland Supply continually gets phone calls and inquiries from customers that think they have a defective lamp when in actuality they simply didn’t push the lamp in far enough.  Pay attention to the old lamp. Re-install and remove the old lamp a few times to get familiar with the how it fit into your projector. When you install the new lamp you can seat it firmly but without too much pressure.  Use the screws to tighten the lamp into its final position.

7.  Hot Projector Lamps are fragile. Do not move or shake the projector until the Projector Lamp has completely cooled. Shock and vibration applied to hot projector lamps may cause the lamp to break or shorten its effective lifespan.  It is recommended that after operation you let the lamp cool at least an hour before handling the projector or lamp.

8.  Do not unplug the projector until the Lamp has properly cooled. After the projector has been shut off, the fan will remain on for a period. This is required for proper cooling of the lamp.  If the lamp is not cooled properly it will cause the life of the lamp to be shortened drastically.  This is a critical point where many people unplug their projector during use in order to turn it off.  By doing this the lamp is extremely hot and has no air circulation resulting in damage or shortened life of the lamp.

9.  Do not turn the projector on and off frequently during presentations. Each time the projector is switched on, the inrush of power causes stress on the Projector Lamp as does the thermal cycles (heating cooling). Try to minimize your on/ off cycles by not frequently turning on and off. If you are not using the unit for less than 30minutes, use a screen saver or video mute option that some models offer.

10.   Wait until the fans stop running before attempting to turn a projector back on after use. Forcing the Projector Lamp to start before it is adequately cool will cause a thermal and electrical shock to the bulb causing the life to be shortened.

It is recommended that you have your projector serviced and maintained approximately every 2 years.

Preferably have the projector cleaned for dust buildup seasonally.

Insist on high quality projector lamps with the original manufacturer’s bulb inside (Made by Philips, Ushio, Phoenix, or Osram).  All lamps are available for sale at PurelandSupply

4 Common Mistakes that Projector Owners Must Avoid


Your projector might be a small unassuming device you throw in your laptop bag between presentations. It might also be a venerated piece of gear carefully installed into your Home Theater.  Maybe you are tasked with handling a school districts worth of SmartBoards...

In any of these situations there are 4 common mistakes people make when they own a projector. These mistakes are not only annoying but can also be costly to rectify.

1. Ordering a Cheaper lamp that "looks" OK.  

Sure, that lamp might be under $50 and says it will run in your projector but as I mentioned in an earlier blog, your cost of ownership can be over 4X what it should be if you had purchased an Original Inside lamp.  Check with the company and see what brand bulb is inside.  Your old lamp will have markings on that bulb. Make 100% sure your new lamp is the same as the old one.  The adage of "if it looks too good to be true, it probably is" holds very true here.

2. Replacing the bulb portion only. 

Always buy a full lamp if its available.  This is/has been advertised by many companies over the years. They offer an explanation that you can get away with only replacing the bulb since the bulb is the only part of your lamp that goes bad right?  In most cases this is not true. While the plastic and metal structure of the lamp will handle tens of thousands of hours of heat, the other parts, such as the lamp's lens and wires will not.  On a lamp for a DLP projector, there is a special coating that is applied to the lens. That coating blocks harmful ultraviolet and Infrared light from entering the optic path of your projector. Since that coating has degraded over the years, your 2500 hours lamp housing now is only blocking a percentage of that UV/IR light.  That now un-blocked light is attacking your optics.  It will cause the lenses inside to heat-up and eventually start melting. The more concerning problem is that you are exposing you, your family or coworkers to dangerous invisible UV/IR light over a few dollars.   I will say, there are a handful of projectors who use a built in IR/UV filter that is made to handle repeated bulb replacement. These are few and far between. For a few dollars more you will have the peace of mind knowing you are protecting your investment as well as the safety of yourself and those around you.  This BenQ 5J.05Q01.001 is a good example. The lens on the front shows the coating. This is also a problem for cheap lamps. They use an inexpensive coating that will not work as well. The glass has a 'green' shine to it. If you see that send the lamp back.

3. Resetting the Lamp timer without replacing the lamp.  

This is a bad idea. While you are probably thinking you are putting one over on the manufacturer, you are only putting your projector at risk.  The time limit on your projector lamp is determined by the manufacturer of your projector. They determine this by seeing how long the lamp can run before the light output drops past a certain threshold (varies per model) and/or when the lamp may be getting deformed from heating cycles(on and off).  Once a lamp begins to deform, it has an increased chance of rupturing.  If you lamp ruptures while running, the chances of damaging the projector also increase dramatically. That "replace lamp" warning is the best time to buy a new lamp.  If your old lamp still works, then put it away as a backup. Your new lamp will be much brighter and will ensure longer functional life of your projector.

4. Not cleaning your projector often enough.  

This is by far the most common mistake I see with projectors. A dirty projector is a projector that is unable to cool properly.  That will lead to shortening the life of the lamp and the projector itself.  No matter how clean your house is, there is dust in the air.  That dust is pulled into the projector via the cooling fans. Electricity generates a static charge which causes the dust to stick to components inside. Over time that dust will cover the heatsinks that cool electronics like the DLP chip. That dust will build up on the leading edge of the Lamp cooling fan blades. Once enough blades are coated the fan will no longer push enough air through the lamp.  When your lamp is running at 500F and that air stops flowing, you can expect 700F+ at the lamp. That corresponds to increased heat throughout the projector. The lamp will finally reach the temperature for the Quartz to become soft. Once that happens it’s only a moment before the arc tube in the center of the lamp ruptures. I recommend having your projector opened and cleaned at least once a year.  At the least, take a vacuum cleaner and some canned air (air duster, not Perri-Air) and blow out and dust through the intake/exhaust vents on the side.   In the future I will address cleaning to a more direct degree.

There are other mistakes and suggestions, but these are the top 4 that I see. A few weeks ago, I had the pleasure of cleaning some NEC V260X projectors that had never been cleaned in 7 years.  They had enough dust that I could weigh it.  They also had bad color wheels because of the heat and would sometimes get as much as 200 hours before a new lamp would fail. After cleaning them and replacing the color wheel, the NP18LP lamp I installed will run for its entire expected life.

What to Do if Your Lamp Stops Working...

...or if your new lamp does not work read these to see if they can help you.

I installed my lamp and now it won’t turn on. Do I have a defective lamp?

There are a few things to check before contacting customer service that may rectify the situation.
·         Make sure your projector is plugged back in.
·         Is the lamp cover fully secured back into place? The projector will not turn on unless it recognizes this access door is closed.
·         It is always best to unplug the unit when replacing the lamp, so make sure it’s properly plugged into a good power outlet. Maybe unplug and re-plug in the projector to be sure.


My projector is plugged in, but I still am not getting light!

     Listen to the projector when you turn it on.  You should hear the exhaust fans after you press the power button for at least a few minutes while the unit tries to start the lamp.  If you do not hear the fans, it could be an indication that the lamp is not seated properly or the lamp access cover is not secure.  Remove and re-install the lamp and carefully replace the lamp cover.  If you still cannot hear any fans, check your power cord and then check to see if there are indicator lights flashing on the projector.
   If you can hear the fans running and there is still no picture, check for any flashing/solid indicator lights on the projector. These lights are how the unit tells us what is going on within the projector, and has a corresponding reference in the owner’s manual.
  Every projector has an owner’s manual available on line for free.  Check the flashing indicator lights against the description in the owner’s manual.  If the description points to a failed lamp, please contact our Customer Service for further assistance.


My lamp is projecting a picture, but I have a message telling me to replace the lamp.  This is a new lamp, why is it saying that?

     Most Projectors have a Lamp Hour Counter or Lamp Timer to keep track of lamp usage.  The units are designed to warn you when the lamp is approaching the end of its life.  When a new lamp is installed, you must manually reset the timer or the projector will not know the lamp has been changed and will count an incorrect amount of hours.  This also means that if you prematurely reset the timer, you will not have a proper hour count on the replacement lamp once installed.  Some projectors will turn off completely and need to be manually reset before they will turn on if the lamp hours are exceeded beyond the factory settings.
- It is always a good idea to check the manual and reset the timer as instructed.



My projector is much dimmer than I would expect with a new bulb. Do I need to send it back?

     Check to make sure the bulb is installed flush with the front of the housing.  It should sit exactly as the old bulb and must be installed the same way or the light will not illuminate the image correctly. Should the bulb be slightly off center, or not aligned correctly the image can be dim, and you will need to contact PurelandSupply for a Return Authorization (RA) Form.


My projector turns on for a few minutes and turns off after installing the new lamp.

     While this could be a defective lamp, it is common for many Projectors to turn themselves off when there is another issue.  Many times the fans will be dusty and not spin correctly.  That will cause the projector to shut down.  Try cleaning the projector with a vacuum to make sure as much dust and dirt is cleaned up as possible.


I installed the lamp and my projector is telling me that it is getting too hot.

     Anytime you replace your lamp, it is a good idea to clean the unit for dust.  Heat is the primary cause of early lamp failure.  By keeping your TV/Projector clear of dust, you will help it keep the lamp at a proper temperature.  While the lamp is out, use a vacuum cleaner to collect any dust from the lamp compartment and the vents so that it does not re-collect in the TV/Projector.
     This is recommended to be done at least when the lamp is changed, but once every 3-4 months is even better.  With proper maintenance of the TV/Projector, the longer it will last.


I received my lamp but it is not the same as the one I removed.

     It is very rare that there can be multiple lamps for a Projector.  Occasionally the manufacturer will switch lamps mid production, which can be confusing and frustrating. This can be resolved very easily with some help from you.  Record any numbers on the lamp/bulb.  Also verify your model # as well as any letters before or after the model number.  Contact our customer service with the information from your old lamp/bulb and we can correct your order and have the issue taken care of.


My projector has a new lamp, but the color of the screen is still wrong.  I see colors where they shouldn’t be and the picture is either flickering or off color completely. Is my lamp defective?

     Our lamps only project a bright white light.  Your Projector processes the color control by shining the white light thought either a color wheel for DLP or LCD panels for LCD units.  The color can only be affected by the internal optics of the projector.  Generally an off color display will not be noticed with an older lamp as it is not operating at full power. With a new lamp, it will be brighter and show any issues that may have been there previously with a lot more clarity.  A new lamp will NOT resolve this as the issue is with the internal optics.
           

I do not see the answer to my issue.  Is there anyone I can talk to?

Hitachi CP-X306 and it's DT00841 Lamp

hitachi lcd projector using dt00841
     The Hitachi CP-X306 is an older LCD video projector with a great reputation.  If you own a CP-X306 that uses the DT00841 lamp, you already know of the hi lumen output of 2600 lumens.  For its time, 2600 lumen (2060 in eco mode) was a bright and useful projector.
The CP-X306 was one of the earlier XGA models.  It has a native resolution of 2014 x 768 which would give you a native 720p resolution if used for Home Theater.

The DT00841 Lamp runs at 220W and feeds a 0.6” set of LCD panels. That gives the projector a respectable 500:1 contract ratio (respectable for 2008 when the unit was first made).    In data mode, the projector can upscale to 1600 x 1200 dpi.  This isn’t useful for home theater but for certain computer driver display applications it is very useful.
The Input panel is one of the most useful features of the CP-X306. 


The CP-X306 also has the capabilities to support Composite,S-Video, Composite, and Dual VGA in (D-sub 15 pin).  The option to use the network jack is a plus. You can then use a newer OS like Windows 10 to connect via a network, so you can skip finding a VGA cable long enough.  If your needs require it, you can also control it via RS232 or USB.  

The Hitachi CP-X306 is a highly flexible projector.  If you own one or plan to buy a used one on eBay give this link a click to treat your Hitachi to a new lamp.  The DT00841 sold by PurelandSupply.com has an original Ushio brand bulb to ensure proper operation.
