life of lcd display in stock

Perhaps you’ve wondered how long a digital display lasts. It’s a great question. One quick search on Google will tell you that an LCD panel has a lifespan of about 60,000 hours, which is equivalent to almost seven years.

Of course, LCDs aren’t the only kind of displays. You also have LED, OLED, QLED, ELD, PDP, and MicroLED, plus many other variations. Obviously, that 7-year estimation will not apply across the board. For the sake of ease, let’s just focus on some of the common types of displays that most of us are familiar with.

Here’s some LCD alphabet soup: There are LED LCD displays, CFFL LCD displays, LED displays, and more. With all these acronyms, it can get a bit confusing. What"s important to note is whether or not the display uses an LCD panel, and how the LCD panel is illuminated. You can read more about thedifferences between types of LCD and LED signage, but these are the most common types:

LCD displaysgenerate images and colors via a Liquid Crystal Display (LCD) panel, which is not self-emitting and requires an external light source to illuminate the image, typically an LED backlight. Their full name "LED-backlit LCD display" is commonly shortened to "LED displays", which is why they"re often confused with the true LED displays we"ve identified above.

Unfortunately, LED backlights used in LCD displays burn out over time. If used at high or maximum brightness, which is necessary for outdoor applications,an LED backlight will last between 40,000 to 60,000 hours. Or, about 4.5 to 7 years.

OLED stands for Organic Light Emitting Diode. OLED displays differ from common LCD displays in that their pixels are self-illuminating. In other words, there is no LED backlight required to illuminate the the display image; everything occurs within the OLED pixels themselves. According to onearticle from the US Department of Energy,OLED screens have a life expectancy of about 40,000 hours at 25% brightness, and 10,000 hours at full brightness. That equates to about 1 to 4.5 years, which is a much shorter (albeit, brilliant) lifetime than an LCD display.

Perhaps you noticed that the acronym QLED closely resembles the acronym OLED. This is not accidental. QLED is basically Samsung’s original design built to compete with OLED technology. However, the two are not the same. QLED stands for Quantum Light Emitting Diode. While QLED is similar to a regular LED design, it in fact differs by using nanoparticles called “Quantum dots” to achieve its unique brightness and color. Samsung approximates that the lifespan ofQLED panels are likely to last 7-10 years. After that, a user is likely to notice traces of degradation.

MicroLED is an emerging display technology, consisting of small LEDs in tiny arrays within each pixel. This technology goes beyond the offerings of the formerly frontrunning OLEDs, with much darker blacks and more radiant contrast levels. And, unlike OLEDs, MicroLEDs are not organic. They are not as subject to burn-in, and thus, have a longer lifespan than OLEDs. However, they are significantly more expensive - so much, in fact, that they aren’t considered a viable option for the majority of consumers.According to Samsung, the lifespan of its MicroLED panels should last about 100,000 hours, or, roughly 11 years.

PDP stands for Plasma Display Panel, and it refers to displays that use small cells full of plasma. The atoms within the plasma emit light upon being charged by electricity. While PDP is generally considered to offer better colors than LCDs, they consume a lot more power and usually cannot be battery-operated.The average lifespan of the newest generation of PDPs is approximated to be 100,000 hours, or 11 years of continual use.

In some ways,reflective LCD panelsoperate similarly to other LCDs, only they have one key difference - they do not require a backlight. Instead, they rely on ambient light (or sunlight) in order to produce images. This opens the door to some groundbreaking possibilities. The first (and most appreciable) is low power consumption. Reflective displays use up to 95% less energy. Not bad - especially in a world that is continually looking for new ways to go green. Take into consideration the financial implications of this. Lower power means less money spent on operating costs.

Being that reflective displays do not require a backlight (a component that is particularly subject to degradation), and since they do not generate as much heat, it is safe to say that the lifespan of these displays should far exceed that of backlit LCD panels (which was 7 years at the high end). However, being that thisinnovative technologyis relatively new, its actual lifespan is therefore more difficult to estimate -- simply because it has yet to be reached.

There are also a few challenges that can affect reflective displays. For one, they rely on ambient light. On a nice sunny day, these displays perform beautifully and can be easily seen in even the brightest of conditions. This performance wanes as the available ambient light decreases. And, since they do not generate light of their own, they are not designed to be viewed under nighttime or extremely low light conditions (without additional lighting features). In short, their images are visible to the degree that ambient light is present. However, in light of this, side light (and front light) options are being explored.

One company at the front lines of this research isAzumo. Azumo has created a light guide that laminates to the front of a display. It requires 90% less energy than the backlight of a traditional LCD display. This greatly improves the problem of low light visibility otherwise encountered, and keeps reflective displays in the same low energy consumption ballpark. One issue, however, is that Azumo currently only offers its light guides for smaller-sized units. If you happen to want this feature applied to a display that is over 10” diagonally, then you’re still on the search for a solution.

Other “pioneer companies” are at the frontier of this research as well, and many are already innovating new solutions to increase the viability of reflective technology - both in their low light visibility and in the screen sizes they are available in. Due to the huge potential offered by reflective technology, it is fair to assume that we will see even greater enhancements to it in the very near future.

One other factor to consider regarding reflective technology is its cost. That reflective layer is more costly to manufacture than many of the backlights it replaces, creating a seemingly greater upfront cost for those who are interested in investing in energy-efficient signage. However, these initial price points are quickly justified as buyers will recognize the significantly lower operating costs and increased longevity (not even including replacement costs of other “expired” displays) that comes with their purchase of reflective display signage. If a backlit LCD panel only lasts 7 years, for example, you’ll have paid for that LCD twice in the period of ten years. A very valid question arises… is that “cheaper” backlight really cheaper? Probably not. It only feels that way at first.

Sun Vision Displayis working hard to create reflective display solutions for the digital signage world. We are currently offering them in 32" and 43" diagonal sizes, with a 55” size in development. These displays are built formany environments. We are thrilled to be bringing such innovative solutions to the market.

LCD is a very popular display technology used by many monitor manufacturers. As a matter of fact, you might be reading this article on a device with LCD technology. And you know that every monitor would come with an estimated lifespan. But what about LCD monitors? Do they have an estimated lifespan?

To answer all of your questions regarding this topic, we have written this post. In this post, we will share how long do LCD monitors last. We will share the estimated lifespan of other display technologies as well. In addition, we will try to share some tips to extend the average lifespan of your particular monitors.

LCD or Liquid Crystal Display is a technology that is found on flat-screen monitors. Typically, the estimated lifespan of an LCD monitor is 30,000 hours to 60,000 hours. That means if you will be using the monitor for 8 hours every day, you will be able to go for 10 to 20 years. Remember, this is an estimation. We cannot tell the exact lifespan of any particular monitor.

This type of monitor does not have a long lifespan. For the record, it has an estimated lifespan of 25,000 to 30,000 hours. This means you can expect 8 to 10 years of lifespan if you are using it 8 hours per day.

LED or Light Emitting Diode is a newer technology. You might already be using an LED display on your phone or monitor. They tend to be very bright and color accurate.

Also, they are a bit pricey compared to the previously mentioned display types. Reportedly, LED monitors can last for up to 50,000 hours. That means it can go up to 17 years if you are using your monitor for 8 hours per day.

OLED is a different type of display panel technology. And, this is also very new and expensive technology. Still, OLED or Organic Light-emitting Diode monitors are known for color accuracy and high brightness and contrast.

However, if you use screensavers or don’t overuse your monitor, an OLED monitor can go a long way. Reportedly, an OLED monitor can have a lifespan of up to 100,000 hours. Theoretically, you can expect an average lifespan of 8 to 15 years from your OLED monitor.

At this point, you are aware of the average lifespan of different types of monitors. But how would you know if your monitor is defective or not? There are a few ways you can be sure about that. So, let’s talk about it…

Of course, if you see that the display is behaving erratically, then it is a sign of defective monitors. In that case, your monitor would turn on or off from time to time automatically. The source of the problem could be a faulty power adapter. Also, the physical buttons on the monitor could be damaged as well.

Have you recently noticed any ghosting on your monitor? It means that you will see a ghost-like appearance on the monitor of a graphic that was showing while the monitor was on. It could also occur when you are playing resource-hungry games with a low-end GPU.

The dead pixel issue is related to the hardware. So it is not possible to fix it without replacing the monitor. Normally, some new monitors even can have dead pixels. It is the absence of pixels on the monitor. For some monitors, there could be only one dead pixel. However, for others, there could be multiple dead pixels.

Last but not least, your monitor can show random issues all of a sudden. You could notice that your monitor’s display has turned blue or greenish. Also, you could see that your monitor is flashing automatically from time to time.

In addition, you could also notice a burning smell if the monitor is defective. In the case of CRT monitors, you might hear a random popping sound when it became damaged. And of course, if you see that your monitor is not turning on anymore, you can be sure that it is already damaged.

Now, whatever the problem on your monitor is, you should contact a professional for this. And if your monitor still has the warranty, then you should send it to the warranty as fast as possible. Most monitor issues can be solved by repairing.

There are many ways you can take care of your monitors. And, if you want to extend the estimated lifespan of your monitor, you should follow some instructions. Let’s talk about them…

Normally, your monitor should come with a power adapter. That adapter should be able to withstand a wide range of voltage. That way, if there is a sudden spike in the electricity flow in your home, your monitor will be protected.

Normally, you will find air vents at the back or bottom of the monitor. When you are running a monitor for a long time, it will get hot. To prevent heat buildup, those air vents are there.

If you are living in an area where load-shedding is a regular occurrence, you should opt for a UPS. That way, your monitor will not be turned off suddenly.

So now you know how long does LCD monitors last. At the same time, you also know this information for other types of display technology. To be honest, most monitors come with a very high estimated lifespan. Still, it is not possible that every monitor will last that long.

How long will your LED display last? In nearly every industry, from retail businesses to concert halls to corporate centers, decision makers need to evaluate the return on investment (ROI) of their LED signage. In most cases, potential buyers go straight to the obvious place: the LED manufacturer’s spec sheet. The industry standard for LED lifespan is 100,000 hours, or about 10 years, and most people assume that’s how long their display will last. But it’s not quite that simple.

The 100,000-hour figure assumes that every diode will be running at full brightness, consistently — which, on an LED screen, is virtually never the case. The lifespan figure can also be misleading because it indicates when a diode degrades to half-brightness, not completely dark. Many other variables affect an LED display’s lifespan; you can’t rely solely on the number on the diode spec sheet.

“The reality is, your screen can often last significantly longer than 100,000 hours,” says Kevin Izatt, a senior product manager in Samsung’s Display division. “We’ve had displays that have been up for 15-plus years with more than adequate brightness. Because the diode is actually only one factor in the lifespan of your LED display.”

The biggest contributor to diode degradation is heat. As you increase a diode’s brightness, it produces more heat. Your display’s physical environment also contributes to the temperature of the diodes, especially for outdoor displays.

The quality of your display’s power supply — and how hard it drives the diodes — can have a significant impact on your screen’s lifespan. The other components being powered, such as fans and electrical components, have their own lifespans as well, which are also impacted by the power supply.

“Fans are mechanical; they break down,” explains Izatt. “And similar to your computer, the electrical components don’t last forever. Together, these factors all contribute to the lifespan of an LED display. Looking at just the diode lifespan doesn’t give you the complete story — almost always, another part will go out first.”

“Something like airflow is very important,” says Izatt. “You need a screen that has good cooling, and a design that allows heat to flow out of the back through vents.”

It’s easy to see why: The circuit boards powering the display release heat, and that heat needs to go somewhere. Without a strong design, thermal stress will degrade the life of the display, except for the highest-quality parts — optimal conditions notwithstanding.

“Lots of variations on the color and brightness you use will impact the life of the diode,” explains Izatt. “For instance, black doesn’t use any of the diodes at all. And if your content is using lots of gray, that’s a much lower power output than white.”

That’s not to say you should hold back on displaying rich, vibrant colors — after all, that’s what LED does best. But it does factor into your product’s life expectancy.

To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program. Samsung will come on site to remove your existing display and provide a discount on a new LED bundle kit.

Traded-in LCD displays that are still operating will be refurbished and resold, and your business will receive a cash rebate. Nonworking displays will be recycled and their parts reused.

You can’t rely on the number on the diode spec sheet; the lifespan of your LED display depends on many more factors. “Overall quality has a tremendous impact on the life of the display that diode specs just don’t take into account,” says Izatt. Your best bet is to look at the purchase holistically and invest in a top-tier product.

LCD display screens are everywhere. You probably own one or more devices with an LCD display screen at home and at work. This includes your TV, computer monitor, watches, clocks, smartphones, and even calculators.

But have you ever wondered about how your LCD display screen works, its lifespan, components, and how it holds up to other emerging display technologies today?

Knowing all these things about your LCD display lets you appreciate your screen all the more. Caring for your device becomes easier when you’re armed with this knowledge.

LCD display screens make use of Liquid Crystal Display technology. The screen is embedded with liquid crystals, a substance that has properties in between a conventional liquid and a solid crystal. Liquid crystals can flow, but their molecules carry a crystal-like solid orientation.

Liquid crystals are responsible for producing an image flashed onto the LCD screen. They don’t emit light, though. Backlights are used to illuminate these crystals.

A display screen is made up of several tiny color blocks called pixels. The term is a portmanteau of “picture” and “element”, denoting pixels as little elements making up an entire screen picture. A screen is typically made up of millions of pixels.

Every pixel on the display screen is made up of red, blue, and green light. These lights can be quickly turned on or off to create an overall moving picture or image.

Now, in LCD displays, pixels are regulated by using liquid crystals for rotating polarized light. Polarized light denotes light waves with vibrations occurring in a single plane. In LCDs, this is achieved by using polarized layers.

Each pixel has polarizing filters on both its front and back. Tiny nematic (twisted) liquid crystals are placed in between these filters. The liquid crystals can be switched on or off electronically through tiny electronic transistors.

When the liquid crystal is turned off, electricity controlled by the transistor stops flowing. The pixel is then turned on, brightening up due to the 90-degree twisting of the nematic liquid crystal. This allows light to pass through both polarizing filters on the pixel, illuminating the pixel by letting light pass through.

When the liquid crystal is turned on, electricity flows through the nematic liquid crystals. They completely straighten out from their twisted state. The polarizing filter in front of the liquid crystal blocks out the light, resulting in the pixel turning off and becoming dark.

A single LCD contains millions of pixels, nematic liquid crystals, polarizing filters, and transistors. They all work together to create images on the screen.

Most LCD monitors have a lifespan ranging from 30,000 to 60,000 hours. That’s equivalent to 5-7 years using the monitor for 24 hours per day. It could also translate to 10-20 years with running the monitor for 8 hours a day, 5 days a week.

The backlight’s life expectancy is the biggest factor in determining the LCD display lifespan. It’s because liquid crystals do not give off light from themselves. The liquid crystals depend on the backlight for illuminating them. Hence, the LCD screen wears off when the backlights dim as it reaches its maximum lifespan.

The backlight serves as the illuminator of the entire LCD display device. Without a backlight, the LCD device remains darkened and hard to use. Backlights are installed directly behind the LCD panel to lighten up the display.

Simple devices such as pocket calculators don’t use a backlight for their LCD screens. Users rely on natural light to see the numbers displayed on such calculators. However, the majority of modern LCD screens such as televisions, computer monitors, smartphones, aviation screen panels, outdoor signages, and medical monitoring devices use backlights as their internal light source.

This type of backlight is the most popular and widely-used light source for LCDs today. Light-emitting diodes are semiconductors that emit light once electric current flows into it. Particles carrying the electric current are called electrons holes. These combine with electrons in the semiconductor, releasing photons (light particles).

Band separations called bandgaps determine the photons’ energy. Furthermore, the photon’s energy dictates which color the LED emits, depending on the emitted light’s wavelength. Various kinds of semiconductors and their corresponding varying bandgaps create different light colors.

Edge-Lit White LED (EL-WLED)– One or more LED rows are placed on the screen’s edge. A special light diffuser is used to scatter the light evenly across the entire display screen. Computer monitors, laptops, notebooks, and even HDTVs are now lit in this way.

White LED (WLED)– The LCD panel’s rear side is lit up with several white-colored LEDs. A diffuser is set in front of the LEDs to help evenly smooth out the light throughout the screen. Some computer monitors and large-screen LCD TVs use this LED technology.

Red-Green-Blue LED (RGB LED)– This technology works like WLED. The difference is that it uses red, green, and blue LED combination lights instead of white lights. Better picture quality and higher color gamut are its advantages over WLED and EL-WLED.

ELP uses electroluminescent materials such as colored phosphors instead of heat to create light. This material is placed in between two conductor layers. The material emits light as a result of an electric current flowing through it. ELPs are mostly used in small LCD screens.

CCFL backlight uses a cold cathode fluorescent lamp as its main light source. This lamp consists of a cathode that isn’t heated electrically by a filament, hence the connotation “cold”.  A diffuser is placed in front of the CCFL lamp to evenly distribute light across the entire screen.

The cathodes used in CCFL produce light by creating a non-heated thermionic emission of electrons. This is accomplished by using discharges in mercury vapor to create an ultraviolet light. This light, in turn, creates a fluorescent coating inside the lamp, resulting in visible light.

Computer monitors and TV screens predominantly used CCFLs for backlights. However, modern manufacturers opt for LED technology instead of CCFL for their devices’ backlights.

HCFL backlights have filaments that need to be heated to excite mercury atoms, cause the current to flow, and ultimately emit light. HCFLs are often used in LCD equipment such as medical devices, custom task-oriented lamps, scanners, and outdoor LCD signs.

Liquid crystals are the heart of an LCD display. This unique substance flows like a liquid but retains many characteristics of solid crystals. They have long and cylindrical-shaped molecules that can twist when changes in molecular orientation happen.

Different liquid crystal families are used in LCD displays. One requirement of such liquids is to exhibit mutual attraction. Also, the molecules in the liquid crystal need to be anisotropic. This means that the liquid crystal molecules have that average structural order along a molecular axis.

Liquid crystals are often sandwiched in between the color filters and the polarizers. They twist and straighten in response to electrical currents applied to them. The movement of liquid crystals controls whether polarized light will pass through the filters or not.

The nematic phase is characterized by the crystal molecules freely moving around the liquid. However, these molecules point themselves to one direction only, making it unique from pure liquid molecules. Nematic liquid crystals are the most common liquid used in LCD screens.

Color filters are found in between the liquid crystals. These filters determine whether the pixel shows red, green, or blue colors when activated. The filters work by independently controlling the pixel’s red, green, and blue sub-pixels. With this, the LCD screen can reproduce all possible colors found in the color space.

The color filters aren’t active elements, though. It’s the liquid crystal molecules that control the light passing through the filters. The color filters simply determine the color the pixel shows based on how much light is passing through them, as determined by the applied electric voltage and the movement of the liquid crystal molecules.

An LCD cell is made up of two polarizing filters. They enclose the LCD display and color filters. One polarizing filter is located in front of the backlight and is horizontal in orientation. The other one is found just beneath the pixel in front and is vertical in orientation. Polarizing filters are typically made of transparent crystals or glass substrates.

The role of polarizing filters is to control which light patterns can pass through the LCD screen. Without these filters, visual images generated by the LCD panel will have a poor contrast ratio and an inferior quality image.

Meanwhile, if the LCD display is arranged in a straightened way, the horizontal light waves that came from the first polarizing filter will be blocked from entering the vertical polarizing filter. The pixel is then turned off and no light illuminates it.

The two polarizing filters need to be vertical and horizontal in orientation, respectively. If the filters are oriented in the same way (ie; both horizontal or both vertical) will block all the light passing through, displaying nothing on the screen.

TFTs are responsible for providing electrical voltage to the LCD display. Each screen pixel has a corresponding transistor, enabling the pixels to easily be controlled in unison through changes in electrical current.

Using TFTs requires less charge and less power to operate the LCD display screen successfully. TFT use also leads to sharper images because each pixel has its own transistor controlling it. The charge given to a certain pixel can be actively maintained even if the screen is refreshed to display another image.

That’s all the basic information you need to know about LCD display screens. Now, you know how an LCD screen works, its possible lifespan, its components, and how it compares to other display technologies.

Armed with this information, you can better appreciate and take care of your LCD display devices. And in case you’re planning to add display devices to your business, the information you’ve learned will help you make educated choices regarding the display technologies you’ll utilize.

Knowing the average lifespan of your monitor is the first step in ensuring the monitor lasts longer. The second tip is to establish how best you can use your monitor while maintaining it in the best condition. Finally, you need to know the signs of a malfunctioning monitor.

This article is a complete guide to monitors" lifespan. We"ve discussed in detail the average lifespan of cathode ray tube monitors, LCD monitors, and so on. Most importantly, we"ve included ways in which you can maintain your monitor to last longer.

A cathode-ray tube monitor has a lifespan of between 20,000 to 30,000 hours. This duration means that your CRT monitor will last up to 10 years of active use. This duration will last if you use the monitor for eight hours every day. After lasting for ten years, you"ll need to repair it or replace it if it"s in an unworthy condition.

The CRT monitor has a shorter lifespan because it uses less efficient cathode-ray tubes. Besides, these monitors are bulky and have fragile units with low durability.

Expectedly, LCD monitors last longer than CRT monitors. Depending on use frequency and maintenance practices, a typical LCD monitor will last for about 30,000 hours to 60,000 hours. This duration translates to between 10 to 20 years of active use, given that you use the monitor eight hours a day.

The reason for the improved lifespan of the LCD monitors is the robust, durable components and the use of more advanced technology. This monitor uses a liquid crystal solution in a polarized material to produce light.

You"ll know that your LCD monitor has reached its lifespan if you notice a drop in the brightness level, display fades on the screen edges, and its backlight tint becomes yellowish.

The lifespan of a LED monitor is higher than that of a CRT monitor and LED monitor. On average, it has a lifespan of 80,000 hours to 120,000 hours of active use. This duration translates to 30 to 40 years if you use it for 8 hours every day.

The reason behind the long lifespan of LED monitors is its production of bright displays with energy efficiency. Its screen technology is also efficient in energy consumption, making the monitor last longer.

Little is known about the lifespan of OLED monitors. However, various research and experiments show that an OLED monitor can last 100,000 hours of active use. This duration implies that your OLED monitor can last for 35 years if you use it for 8 hours a day.

How long your OLED monitor lasts largely depends on how you use it. Exposing the OLED monitor to harsh working conditions degrades its components, resulting in early burn-in. Long session gaming on these monitors also limits its lifespan.

From a general point of view, any monitor will last longer when built with durable and quality materials, provided you use it under the recommended conditions.

The number of hours you use your monitor per day can extend or lower the computer monitor lifespan. The average estimate of hours per day you should use your monitor is 8 hours. Keeping the monitor active past 8 hours can lower its lifespan. Similarly, using the monitor for fewer hours than 8 hours per day may increase its duration, provided you keep it at optimum condition.

In this regard, you should clean your monitor frequently using a soft microfiber cloth. Also, repair the monitor immediately you notice a malfunction.

The tips for improving the lifespan of your monitor are listed below.Always observe the recommended usage condition of the monitor as stipulated by the manufacturer.

Once in a while, open up the monitor to clean the internal components—dust off any dust and dirt. When dust combines with moisture, it can result in short-circuit as they conduct electricity.

Keep the monitor"s air vents open. The air vents are found at the sides of the monitor. Keeping them open eliminates heat buildup in the monitor. If the air vents are blocked with dust, you can remove them using a vacuum cleaner or soft brush.

Calibrate the screensaver to solid black mode. This mode has low power consumption and the LCD"s backlight bulb to last longer. With this mode, you won"t experience burn-in issues easily.

If your monitor has a burn-in, it will frequently display some unintended graphics on the screen. You can address the burn-in issue by placing a screensaver at the exact point the graphics show up. You can also use JScreenFix software.

Your monitor may develop unusual behavior when it nears the end of its lifespan. It may switch on or off unexpectedly, hibernate suddenly, and show a black screen more often. The most common cause of this malfunction is a faulty power supply unit.

A faulty screen display does not display images or graphics. Instead, it lights up but shows a blue screen. You shouldn"t confuse this problem with the black screen. If the screen is black, then it is a power supply issue.

Computer monitors have no scheduled replacement timelines. How often you replace it depends on how well you use the monitor. If you observe the recommended operating conditions and observe maintenance practices, the monitor will last longer, eliminating the need to replace it.

Faulty monitors have many signs. You can tell your monitor is faulty when it turns on and off unexpectedly, black or blue display, or horizontal and vertical lines on the screen.

You can extend the life of your monitor by following the recommended operating conditions, observing maintenance practices, lowering brightness and gamma settings, and using voltage stabilizers.

Choosing whether to repair or replace your monitor depends on the monitor"s condition, age of use, and the repair price vs. purchase price. You can repair your monitor if its damage can be repaired at a lower cost. However, replace the monitor if it is old and the repair cost equals the purchase price for a new one. Also, you can buy a refurbished monitor, but they come with some risks. For instance, they may not be reliable and long-lasting as the new monitors. Additionally, the warranty policy may be for a limited time.

Early flat-screen TVs, especially plasmas, were notorious for their limited lifespan. This has improved dramatically with the latest technology, however. You can rest assured that any new TV you buy now should last you until you decide to change it.

A screen"s lifespan is measured as "half life", which is the time it takes for the internal lamp to fade to half its original brightness. Your old CRT set has an average half life of around 25,000 hours, but the latest flat screens claim to last up to twice as long.

LCDs are said to have a slightly longer lifespan to plasmas, but the difference is not particularly significant. Plasma"s half life ranges between 30,000 to 50,000 hours, while LCD offers around 60,000 hours.

In real terms, if you watch the TV for an average of 4-6 hours a day, then a screen with a half life of 30,000 hours will last you over 16 years -- by which time we"ll probably all be watching holograms!

It"s possible to change the lamp for both plasmas and LCDs, but not all manufacturers offer this service and the cost is usually greater than the expense of simply buying a new TV.

There are several technical problems that can afflict flat screens during their lifespan, including dead pixels, backlights and, in plasmas, screen burn -- where a lasting image leaves an imprint on the screen. But manufacturers don"t usually offer repairs and it"s best to find a screen with a good guarantee.

Equally important to extending the lifespan of a flat-screen TV is finding a model with a future-proof specification. This includes features such as integrated Freeview, high-definition compatibility and multiple HDMI connections.

Sony claims the model you mentioned, the KDL-40W2000, has a half life of around 60,000 hours -- more than enough in this day and age. The screen also features a future-proof specification and comes with a free three-year warranty from good suppliers.

the contrast settings remains after being set, i.e., depends on calculator main hardware. It uses a four-bit range parameter (0 to 15), usually in the X-register. If you have HEPAX, try HEPAX function 005. Default contrast is 5 (0101) instead of expected 7 (0111)... Go figure!

For real-life application we used many of these in a commercial automated capuccino machine, and they had no problems (using a reputable Asian brand name of module) provided they were mounted in a stress-free way.

The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.

For over 20 years Newhaven Display has been one of the most trusted suppliers in the digital display industry. We’ve earned this reputation by providing top quality products, services, and custom design solutions to customers worldwide.

5. Longer Life: These industrial grade displays can be used for 50,00 hours. Standard TV average life is only 15,000 hours. At (12) hours a day, (7) days a week that averages to 11 years of usage. Save money on having to replace a standard TV, that typically burns out after just the second year of continuous use.

Fifty years ago, a pair of physicists in a Swiss laboratory began untangling a mystery that had been intriguing a handful of other scientists for several years.

Here was their conundrum: Could miniscule electrical jolts unwind the spiral molecular structure of a new substance known as “liquid crystal,” causing the crystals to block light, then re-twist them and allow light to pass through again?

The physicists – Dr. Martin Schadt and Dr. Wolfgang Helfrich – placed the liquid crystal between two plastic surfaces carrying a grid of transparent electrodes. In so doing, they discovered they could create individual picture elements, or “pixels,” which could be used to form shapes.

They filed a Swiss patent for the idea on Dec. 4, 1970. Though it attracted scant attention at the time, the milestone now stands as the birthdate of the liquid crystal display (LCD) – the technological platform which has transformed consumer electronics and presented a brilliant new way to view the world.

Early LCD developers took a few years to figure out that specialty glass, not plastic, was the best stable substrate for the delicate LCD circuitry and the color backplane component. Once they did, they turned increasingly to Corning to supply them with extraordinarily stable, flat, fusion-formed glass, able to preserve the critical properties of the liquid crystal and withstand high processing temperatures.

And LCDs rapidly transformed from “passive matrix” models, mostly used in pocket calculators and digital watches, to “active matrix” LCDs in which each sub-pixel was controlled with an isolated thin-film transistor. AMLCDs enabled wide viewing angles; brilliant, fast-moving images; and high-resolution images that had never been possible before.

Corning Incorporated was a critical player in this development, and eventually became the world’s leading supplier of LCD glass substrates. And Corning® EAGLE XG® Glass, the world’s first LCD substrate with no arsenic or other heavy metals, went on to exceed sales of 25 billion square feet, making it one of the most successful products in Corning’s history.
