I have a few questions about a Sharp XG-1500U Projector!?

Ok, I just bought a Projector on ebay. Can you give me the specs on it. Here is the link for it: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=300214167036&ssPageName=STRK:MEWN:IT&ih=020. What is the weight? What are the hours allowed on the bulb or lamp? How many lumens? Wierd: How long does it take to turn on/off? Does it handle VGA and RCA? I went to google.com and typed in the name of the projector. This is what I came up with. It shows me, like, nothing:http://www.projectorcentral.com/Sharp_XG_Series-XG-1500U.htm. Thanks!

It's an oldie and I don't remember much about it but it's a 480p 4:3 aspect ratio projector. The bulb should last 2000 hours (I checked, a new one is around $380). For $100, you should be able to have some fun with it. It will have some serious screen door effect (it looks like your seeing the picture through a screen door) but hook it up to a dvd player and sit further back.

Organic Light Emitting Diodes-Smart Elements For Displays

 

 

 

Organic light emitting diode-Smart element for display.

 

An organic light emitting diode (OLED), is a light-emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. This layer of organic semiconductor material is formed between two electrodes, where at least one of the electrodes is transparent.

OLED can be used in television screens, computer monitors, small, portable system screens such as cell phones and PDAs, watches, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. OLEDs emit less light per unit area than inorganic solid-state based LEDs .

 

OLED displays have certain advantages over liquid crystal displays (LCDs). OLED displays do not require a backlight to function. Thus, they can display deep black levels and can be thinner and lighter than LCD panels. OLED displays achieve higher contrast ratios than either LCD screens using cold cathode fluorescent lamps (CCFLs) or the more recently developed LED .

OLED Components:An OLED is a device that is 100 to 500 nanometers thick or about 200 times smaller than a human hair. OLEDs can have either two layers or three layers of organic material; in the latter design, the third layer helps transport electrons from the cathode to the emissive layer. In this article, we'll be focusing on the two-layer design.

 

An OLED consists of the following parts:

1.Substrate (clear plastic, glass, foil) - The substrate supports the OLED.

 2.Anode (transparent) - The anode removes electrons (adds electron "holes") when a current flows through the device.

3.Organic layers - These layers are made of organic molecules or polymers.

4.Conducting layer - This layer is made of organic plastic molecules that transport "holes" from the     anode. One conducting polymer used in OLEDs is polyaniline.

5.cathode: The cathode gives electrons to the emissive layer

 

 

 

 

OLED is com posed of an emissive layer, a conductive layer, a substrate, and both anode and cathode terminals. The layers are made of organic molecules that conduct electricity. The layers have conductivity levels ranging from insulators to conductors, so OLEDs are considered organic semiconductors.

OLEDs consisted of a single organic layer of poly(p-phenylene vinylene).

Multilayer OLEDs can have more than two layers to improve device efficiencyand conductive properties,  the layers are  chosen to aid charge injection at electrodes by providing a more gradual electronic profile or block a charge from reaching the opposite electrode and being wasted.

.

 

 

Schematic of a 2-layer OLED: 1. Cathode (−), 2. Emissive Layer, 3. Emission of radiation, 4. Conductive Layer, 5. Anode (+)

 

Operation ofOLEDs:

OLEDs emit light in a similar manner to LEDs, through a process called electrophosphorescence.

The process is as follows: 1. the voltage is applied across the OLED.

2.An electrical current flows from the cathode to the anode through the organic layers (an electrical current is a flow of electrons).

The cathode gives electrons to the emissive layer of organic molecules.

       The anode removes electrons from the conductive layer of organic molecules.

3.At the boundary between the emissive and the conductive layer , Electrostatic forces bring the electrons and the holes towards each other and they recombine. This happens closer to the emissive layer, because in organic semiconductors holes are more mobile than electrons. The recombination causes a drop in the energy levels of electrons, accompanied by an emission of radiation whose frequency is in the visible region. Hence this layer is called emissive.

 

        4.When this happens, the electron gives up energy in the form of a photon of light . The OLED emits    

           Light.

        5.The color of the light depends on the type of organic molecule in the emissive layer.

             Manufacturers place several types of organic films on the same OLED to make color displays.

         6.when the anode is put at a negative potential with respect to the cathode then holes               move tothe anode and electrons to the cathode, so they are moving away from each other and do not recombine.In this case OLED  is not functions as light emitter. 

 

 

7.The intensity or brightness of the light depends on the amount of electrical current applied: the more current, the brighter the light

8.Anode material in OLED must have high work function where cathode material must have low workfunction.so generally Indium tin oxide is used as the anode material. It is transparent to visible light and has a high work function which promotes injection of holes into the polymer layer. Metals such as aluminium and calcium are often used for the cathode as they have low work functions which promote injection of electrons into the polymer layer

 

Types of OLEDs:

There are several types of OLEDs & each type has different uses.

 

1.Passive-matrix OLED

2.Active-matrix OLED

3.Transparent OLED

4.Top-emitting OLED

5.Foldable OLED

6.White OLED

Passive-matrix OLED (PMOLED)
PMOLEDs have strips of cathode, organic layers and strips of anode. The anode strips are arranged perpendicular to the cathode strips. The intersections of the cathode and anode make up the pixels where light is emitted. External circuitry applies current to selected strips of anode and cathode, determining which pixels get turned on and which pixels remain off. Again, the brightness of each pixel is proportional to the amount of applied current.

 

PMOLEDs are easy to make, but they consume more power than other types of OLED, mainly due to the power needed for the external circuitry. PMOLEDs are most efficient for text and icons and are best suited for small screens (2- to 3-inch diagonal) such as those you find in cell phones, PDAs and MP3 players. Even with the external circuitry, passive-matrix OLEDs consume less battery power than the LCDs that currently.

AMOLEDs have full layers of cathode, organic molecules and anode, but the anode layer overlays a thin film transistor (TFT) array that forms a matrix. The TFT array itself is the circuitry that determines which pixels get turned on to form an image.

 

AMOLEDs consume less power than PMOLEDs because the TFT array requires less power than external circuitry, so they are efficient for large displays. AMOLEDs also have faster refresh rates suitable for video. The best uses for AMOLEDs are computer monitors, large-screen TVs and electronic signs or billboards

Transparent OLED
Transparent OLEDs have only transparent components (substrate, cathode and anode) and, when turned off, are up to 85 percent as transparent as their substrate. When a transparent OLED display is turned on, it allows light to pass in both directions. A transparent OLED display can be either active- or passive-matrix. This technology can be used for heads-up displays.TOLEDs can greatly improve contrast, making it much easier to view displays in bright sunlight.This technology can be used in Head-up displays, smart windows or augmented reality applications

 

Top-emitting OLED
Top-emitting OLEDs have a substrate that is either opaque or reflective. They are best suited to active-matrix design. Manufacturers may use top-emitting OLED displays in smart cards.

 

Foldable OLED
Foldable OLEDs have substrates made of very flexible metallic foils or plastics. Foldable OLEDs are very lightweight and durable. Their use in devices such as cell phones and PDAs can reduce breakage, a major cause for return or repair. Potentially, foldable OLED displays can be attached to fabrics to create "smart" clothing, such as outdoor survival clothing with an integrated computer chip, cell phone, GPS receiver and OLED display sewn into it.

White OLED
White OLEDs emit white light that is brighter, more uniform and more energy efficient than that emitted by fluorescent lights. White OLEDs also have the true-color qualities of incandescent lighting. Because OLEDs can be made in large sheets, they can replace fluorescent lights that are currently used in homes and buildings. Their use could potentially reduce energy costs for lighting.

In the next section, we'll discuss the pros and cons of OLED technology and how it compares to regular LED and LCD technology.

Stacked OLED

Stacked OLED (SOLED) uses a pixel architecture that stacks the red, green, and blue subpixels on top of one another instead of next to one another, leading to substantial increase in gamut and color depth, and greatly reducing pixel gap. Currently, other display technologies have the RGB (and RGBW) pixels mapped next to each other decreasing potential resolution.

Inverted OLED

In contrast to a conventional OLED, in which the anode is placed on the substrate, an Inverted OLED (IOLED) uses a bottom cathode that can be connected to the drain end of an n-channel TFT especially for the low cost amorphous silicon TFT backplane useful in the manufacturing of AMOLED displays.[44]

Advantages OLED

OLEDs offer many advantages over both LCDs and LEDs:

      1.The plastic, organic layers of an OLED are thinner, lighter and more flexible than the crystalline layers in an LED or LCD.

2.Because the light-emitting layers of an OLED are lighter, the substrate of an OLED can be flexible instead of rigid.

3.OLED substrates can be plastic rather than the glass used for LEDs and LCDs.

4.OLEDs are brighter than LEDs.

5.Because the organic layers of an OLED are much thinner than the corresponding inorganic crystal layers of an LED, the conductive and emissive layers of an OLED can be multi-layered.

6.LEDs and LCDs require glass for support, and glass absorbs some light. OLEDs do not require glass.

7.OLEDs do not require backlighting like LCDs .since  OLEDs generate light themselves

8. As OLEDs do not require backlighting, they consume much less power than LCDs .This is especially important for battery-operated devices such as cell phones.

9.OLEDs are easier to produce and can be made to larger sizes. Because OLEDs are essentially plastics, they can be made into large, thin sheets.

10.OLEDs have large fields of view, about 170 degrees. OLEDs produce their own light, so they have a much wider viewing range.

Disadvantages OLED
OLED seems to be the perfect technology for all types of displays, but it also has some problems:

1.Lifetime - While red and green OLED films have longer lifetimes (46,000 to 230,000 hours), blue organics currently have much shorter lifetimes (up to around 14,000 hours.

Manufacturing - Manufacturing processes are expensive right now.

2.Water - Water can easily damage OLEDs.

Color balance issues

The OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light. This differential color output change will change the color balance of the display and is much more noticeable than a decrease in overall luminance. This can be partially avoided by adjusting colour balance but this may require advanced control circuits and interaction with the user, which is unacceptable for some users.

Other companies

The Optimus Maximus keyboard developed by the Art. Lebedev Studio and released early 2008 uses 113 48×48-pixel OLEDs (10.1×10.1 mm) for its keys.

OLEDs can be used in High-Resolution Holography (Volumetric display). Professor Orbit showed on May 12, 2007, EXPO Lisbon the potential application of these materials to reproduce three-dimensional video.[citation needed]

OLEDs could also be used as solid-state light sources. OLED efficiency and lifetime already exceed those of incandescent light bulbs, and OLEDs are investigated worldwide as a source of general illumination; an example is the EU OLLA project.[75]

On March 11, 2008 GE Global Research demonstrated the first successful roll-to-roll manufactured OLED, marking a major milestone towards cost effective production of commercial OLED technology. The four year, $13 million research project was carried out by GE Global Research, Energy Conversion Devices, Inc and the National Institute of Standards and Technology.[76][77]

Chi Mei Corporation of Taiwan, demonstrated a 25" Low-Temperature Polycrystalline silicon Active Matrix OLED at the Society of Information Displays (SID) conference in Los Angeles, CA, USA on May 20–22, 2008.

On June 5, 2009 DuPont demonstrated a new material that can be printed, so called solution deposition. The breakthrough is the ability to produce economically scalable and durable OLED displays at the 2009 International Symposium, May 31-June 5, 2009, Henry B. Gonzalez Convention Center, San Antonio, TX, USA

The use of OLEDs is also being investigated for the treatment of cancer by photodynamic therapy.[78]

On 30 Aug 2009, South Korea's LG Electronics said it would launch a 15-inch television set using AM-OLED displays for sale in November.[79][80]

According to Isuppli Corp,[81] upward momentum of OLED Shipments for primary cell phone displays is their expectation in coming years. They claimed that global shipments of OLED main cell phone displays would rise to 178 million units in 2015, up from 22.2 million in 2009. In other words, the shipments will rise eightfold by 2015. Therefore, it's evident that the manufacture of OLED display and OLED equipment by Samsung, DuPont, Anwell, Chi Mei Corporation, etc has expanded dramatically in recent years.

built dvd tuners
What built-in digital tuners are compatible with a QAM tuner?

My local cable TV company says that if I buy my own DVD recorder that it has to have a built-in QAM tuner but I'm having trouble locating such a beast. (Yes I've called Best Buy, etc. and no one can give me a straight answer.)
So can anyone tell me what digital tuners are compatible with a QAM tuner?
Thanks!

QAM isn't the standard for OTS, 8VSB is.

QAM is what you need to look for in the manual or spec list.

There is a good chance if it has an ATSC tuner it can tune QAM.

About the only digital tuners that cannot tune QAM are the SD digital converters made to get digital broadcast on an older TV. Those are prohibited from tuning QAM as part of the coupon program to purchase them.

Shopping for a Big Screen TV means avoiding lots of people trying to dazzle you with new technology.

You have to side-step slick TV salesmen talking about "DLP", "EDTV" or "1080i". You have to outsmart internet con artists selling "gray market" Plasmas. And you have to ignore bone-headed advice from Fred, the neighborhood know-it-all.

Mistake #1: Don’t Buy A "No-Name" Plasma TV!
The most important decision you can make when buying a big screen TV is to decide not to buy a "No-Name". A device as complex as a LCD, Plasma or DLP TV must be manufactured with the finest components by dozens of expert technicians working in multi-million dollar plants. "No-name" companies use none of those.

Mistake #2: Never Trust A "Seeing Eye" TV Salesman!
If you walk into a TV showroom and don’t know EDTV from HDTV, some slick salesman will smile and eat you for lunch! Don’t let salesmen make choices for you, or you’ll end up with some outdated TV his boss wants to get rid of. Or you’ll end up with screen burn-in on your new Plasma when your son hooks up his Playstation 3; or suffer with a dim display in your brightly lit living room. Do a little research before you make a purchase; it’s not difficult.

(If you’re not familiar with some of the terms used above - DLP, EDTV, LCD - Google the "123 Guide To Plasma TV.com")

Mistake #3: Don’t Buy From A "No-Name" Retailer!
It’s important to buy your Plasma TV from a reputable dealer selling brand name merchandise. The return of a faulty $2000 Plasma TV won’t bankrupt Wal-Mart or Sony; but could devastate a Mom and Pop electronics store. Try to make major purchases from a major retailer’s website; make sure they offer a good return policy and have brand name Plasmas at a discount price.

Mistake #4: Don’t Fall For Plasma Internet Scams!
We’ve all seen what look like great deals on Plasma TVs online. But exactly what is a great deal? It means getting GREAT MERCHANDISE at a GREAT PRICE. It’s not a great deal if you get CRAPPY MERCHANDISE at a GREAT PRICE! You don’t want your "new" Plasma to be a returned or refurbished item. Avoid "gray market" or "B stock" merchandise, and avoid sellers who aren’t authorized retailers.

Mistake #5: Don’t Play Video Games On A Plasma Television!
The chance of screen burn-in on a Plasma TV has been greatly reduced by improved technology, but not eliminated. Computer programs, video games, stock tickers and station logos can burn permanently into the screen, ruining your expensive TV. LCD and DLP TV screens cannot suffer screen burn-in, ever.

Mistake #6: Don’t Let A Know-It-All Pick Your TV!
Your neighbor Fred says he’s an expert on Big Screen TVs, and volunteers to help you buy one. Fred may be a good guy. . . he may even know the difference between DTV and DLP. But Fred may also be a Boob blowing smoke out the rear of his shorts. How can you tell? Rely on the only person you can trust to look out for your interests . . . you! Listen to Fred, but take him with a grain of salt . . . and do your own research!

Mistake #7: Don’t Try To Bring Home A Plasma TV By Yourself!
There was a time you could go to Circuit City, buy a 19-inch color TV, throw it in the back seat and take it home . . . those days are over! Shipping a Plasma TV to your home is the only sensible way to get it there; it’s too big, expensive, heavy and delicate to be shoved in the trunk of a car. Your retailer will arrange shipping for you; make sure that insurance and order tracking are included in the deal. Don’t sign for delivery until you’ve inspected your TV for damage.

Mistake #8: Don’t Install A Plasma TV Without Help!
A Plasma TV, although thin, is actually very heavy. A 50-inch Plasma TV can weigh over 160 pounds. Mounting a Plasma TV on it’s table stand is a three person job; call some strong friends over. The delivery people will put your TV on the curb, or in your living room, depending on what you paid for. They won’t install your TV on a wall mount, that service costs $200-$300.

Mistake #9: Don’t Fail To Connect A Dolby Sound System!
You shouldn’t settle for the sound coming from your TV speakers. Attached to your TV, a Dolby 5.1 Surround Sound amplifier sends six separate channels of sound through speakers in front of, on both sides of and behind the viewer. Home Theater Systems start as low as $250 and go into the thousands; they include an amplifier, five speakers, wire and a sub woofer. Dolby 7.1 is even more advanced with eight sound channels.

Mistake #10: Don’t Forget To Budget For Peripherals!
For full enjoyment of your new Plasma TV, you’ll need lots of other stuff: HDMI cables for each peripheral, surge protectors, a TV stand or wall mount, a hdtv dvd player and digital cable for High Def broadcasts. You’ll also need a Home Theater System with at least Dolby 5.1 Surround Sound and a comfortable viewing area. I’m not trying to scare you . . . a modest system can cost less than $300, A good system between $800-$1000 and a Top-of-the-Line system $1500 and up.

Well, there you have it . . . the 10 Biggest Bone-Headed Mistakes you could make when shopping for the perfect Plasma TV! Avoid them like the plague!

Good luck . . . I hope you find the Plasma TV that will thrill your family for years to come!

It’s as easy as 123!

I need a 26 inch tv for my bed room. I went to best buy.com and I narrowed it down to these two choices. I don't know which one I should buy.

A 26 inch toshiba

I manage to find a 26 inch one of this in my local store
But I don't know choose which one I want. The toshiba is cheaper but the samsung is a LED.But hte toshiba also has a dynalight backlight control.

Samsung is a better quality brand and it is LED TV that provide you better picture qualiy, deeper black.

but if you want 26inch I would suggest Panasonic VIERA X1 Series TC-L26X1 26-Inch 720p LCD HDTV, good quality, good pictures and a bit cheaper.

Where's the cheapest place I can get double mats for framing photos--either pre-cut or special order?

I'm want to buy about 25 double-mats -- all the same interior and exterior dimensions, but whenever I look at prices, I have to compute type of mat, cutting fee, shipping fee, etc., and doing that for 10 different matting websites is confusing to the point I have to call some of them up to figure out the final fee. Anyone have a recommendation for a matting website? Or should I try eBay or a store?

Seriously. Try buying a matting knife (cheap) and practice making your own
