lcd screen lifespan manufacturer

LCDs have a lifespan of about 50,000 hours, or 5 years — half the lifespan of LED. To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program.

Flat-panel LCD TVs have a lifespan newly approaching 100,000 hours on average. The lifespan of an LCD TV is generally longer than that of similar-sized plasma televisions.

LED technology has improved drastically in recent years improving quality while driving costs down. LED is a bigger investment up front but generally has a lifespan of about 100,000 hours. LCD is cheaper and generally more familiar. A LCD screen typically has a lifespan of about 50,000 hours.

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.

In addition to humidity and temperature exposure, cyclic loadings and handling conditions (bending, repetitive shock, and drop loading) have been shown to cause failures in LCDs.

While LCDs are not susceptible to burn-in the same way CRT monitors are, LCDs suffer from what manufacturers call image persistence. Like the burn-in on CRTs, image persistence on LCD monitors is caused by the continuous display of static graphics on the screen for extended periods.

Lifespan. LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable. Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured).

LED TVs are more energy-efficient as these models use light emitting diodes (LED) for backlighting. These TVs consume less power as compared to cold cathode fluorescent lamps (CCFL), which most LCD TVs use. This results in a power savings of up to 30%.

If you"re still wondering whether you should opt for an LCD or LED monitor, the answer is simple– LED displays are always the better choice, regardless of whether you"re looking for a better viewing angle, picture quality, or anti- eye fatigue features.

Is LED or LCD Better for the Eyes? An LED display provides the option to dim the backlight, along with other eye comfort features. Not only that, it provides a wider viewing angle without harming image quality. Therefore, an LED display is far better for your eyes than an LCD.

On average LCD flat-screen TV is slated to have a half-life of roughly around 60,000 hours. LG LCD TVs fit squarely in with this statistic, as they last for anywhere between 40-60,000 hours, which would translate to 5 to 7 years.

An LCD or LED TV may not perform well under extreme temperature conditions. In the cold, the response time of an HDTV picture may lag. For this reason, many LCD and LED television manuals will specify a safe-operating-temperature range. In most HDTVs, this range is about 50–90°F.

Quite simply, the QN90B is one of the best LCD TVs you can buy, so it"s especially good that this TV is available in such a wide range of screen sizes. Like the Hisense U8H, the Samsung QN90B achieves excellent picture quality by way of mini-LED backlighting, local dimming, quantum dot color, and a 120 Hz refresh rate.

OLEDs are true emissive components that produce light on their own and do not require a light source. Meaning they produce a light that"s more natural and less harsh on your eyes. OLED TVs also provide excellent color and contrast because they do not use light from other sources to display colors, as LCD/LED TVs do.

According to manufacturers, the lifespan of an LED TV varies between 4 and 10 years (between 40,000 and 100,000 hours), depending on usage and maintenance. Of course, factors like type, brand, location and environment play a crucial role.

When it comes to picture quality, full-array LED monitors are almost always superior to LCD monitors. But bear in mind that only full-array LEDs are superior. Edge-lit LEDs may actually be inferior to LCD monitors.

Liquid Crystal Displays (LCD) remain a popular choice for televisions and computer monitors. Unfortunately, these can be affected by a defect called backlight bleeding. Occurring when light isn"t entirely blocked around a display"s bezels, the imperfection is fixable in some cases, although not always.

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.

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.

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 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.”

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.

Much has been made of the longevity of LCD displays, at least compared to plasma monitors. The conventional wisdom is that LCD televisions last longer than their plasma TV counterparts, which is true. The problem is, a lot of people extrapolate from this that either (a) LCD displays last forever or (b) LCD monitors suffer no picture "wear" over time. Neither of these suppositions is correct.

Flat-panel LCD screen displays have a lifespan approaching 60,000 hours. The lifespan of an LCD display is generally longer than that of similar-sized plasma displays. Some manufacturers even claim that their LCDs can last upwards of 80,000 hours when used continuously under controlled conditions (e.g., in a room with "standard" lighting conditions and 77° temperatures throughout). Just how realistic such claims are is debatable. After all, whose living room has no windows and remains at a perfectly comfortable 77 degrees year-round?

In any case, the pictures on LCD displays will show some "wear" because they are generated by powerful lamps, which, like any lighting appliance, will dim over time and with use. The picture you see will dim ever so slightly as the lamp itself dims.

Therefore, the most important thing to consider when it comes to the lifespan of your LCD TV is the actual lifespan of the light source in your LCD. LCD TVs last as long as their lightsources do. So, the lightsource in your LCD monitor is the critical component of your LCD display unit.

The quality of your lightsource is particularly important for maintaining a proper white balance on your TV. As these florescent bulbs age, colors can become unbalanced, which could result in too much red, for example, in your picture. So, it pays to buy name-brand displays. You will definitely pay more for better LCD display brands like Sharp, Toshiba, JVC, or Sony than you will for cheap Chinese or Korean variety knock-offs, but you"ll get a backlighting bulb of higher quality and, in the end, a TV whose colors will stay truer longer.

To ensure the integrity of your lightsource for the duration of your LCD display"s lifespan, you will definitely want to adjust the CONTRAST setting of your LCD TV. Too high of a CONTRAST level will prematurely age your lightsource because it will have to work harder to maintain such light intensities. Your best bet is to keep your CONTRAST set appropriately for the conditions under which your view your LCD display. Higher light levels require slightly higher CONTRAST levels, while lower ambient light levels demand less CONTRAST.

You will also want to pay attention to the warranty for this particular feature, since it can be shorter than for the display as a whole. This means you might have to buy a whole new LCD monitor because the coverage on its backlight has expired. Moreover, some bulbs can be replaced, while others are built in to the unit itself. You should definitely do some research on the backlighting system, how it"s configured, and how it"s warranted.

Note: Sharp is currently the only manufacturer that makes LCD displays whose lamps can be changed out. This is definitely something to consider, given that LCD monitors dim as their lightsources do, so being able to replace its lamp will restore your picture to "like new" levels.

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 life span of traditional LCD screens is between 40,000 and 60,000 hours, and the more recent popular OLED screens have a life span of about 30,000 hours. If you look at the phone for an average of 3 hours a day, it can also last 10,000 days, or 27 years, which is far more than the average user’s replacement cycle.

Nowadays, OLED screen has become the standard for high-end smartphones, compared with the traditional LCD technology, it is not only thinner, lower energy consumption, high brightness, can display pure black, faster response time, but also can be made into a curved screen, giving people a different visual impact

The cell phone industry in these two years the hottest words than “full-screen” and “under-screen fingerprint recognition”, if there are still phones can not support these two functions, it is estimated that many people will be seriously considered, after all, the under-screen fingerprint unlocking posture is more handsome, and want to use the under-screen fingerprint unlocking, but not only an additional under-screen fingerprint reader also needs an OLED screen.

Why under-screen fingerprint recognition can only be used in OLED screen? This is because it is relatively “soft”, OLED in the construction of only two layers of thin film and glass or plastic substrate, and through the OLED material self-lighting characteristics, can be without backlight module and color filter, also do not need the general LCD panel filling liquid crystal process, can achieve 0.5-1.8mm thickness. Nowadays, most of the under-screen fingerprint recognition is optical fingerprint program, so relatively in the use of optical fingerprint program, OLED screen will be more suitable.

Why can’t under-screen fingerprint recognition be used in LCD screen? This is because it is relatively “hard”, the working principle of LCD is mainly composed of two parallel glass plate, between the two layers of glass plate and then by the liquid crystal layer and polarizer, color filter layer and so on material composition. In simple terms, LCD is the need for backlight irradiation to display, so is the result of LCD screen than OLED screen thicker, light transmission is weaker, not conducive to the use of under-screen fingerprint identification.

Since OLED screen can use under-screen fingerprint recognition, why do not all cell phone manufacturers use OLED screen? This involves the advantages and disadvantages of LCD screens and OLED screens.

OLED screen has the advantage of being able to achieve the integration of on-screen fingerprints without opening holes, as well as a wide color gamut, but there are also certain defects, short life, easy to burn the screen (if the same screen bright screen for a long time, the screen will leave that long-term static picture traces), low pixel density, etc., and the overall technology is not mature enough, due to the low pixel density of OLED screen, it is difficult to have 2K, 4K screen.

LCD screen, although temporarily can not use under-screen fingerprint recognition, but, LCD screen is also the advantages of OLED can not be comparable, there is a natural DC dimming more eye protection, color is also natural, drawing people prefer LCD, screen life compared to OLED long, but also not easy to change color, also do not have to worry about using a long time after the problem of burning screen, which is also the reason why LCD loyal users like it.

In addition, LCD screen does not stimulate the human eye, will not cause eye fatigue, especially open eye protection mode filtering blue light, less damage to the eyes. oled screen will leave residual shadows, eye damage, even dimming can not be completely avoided.

Have you ever thought How long does a monitor last? or wondered what the lifespan of a monitor is? After all, monitors are the significant peripheral device of a PC.

Furthermore, much of the time it possibly winds up changing for another one when we need a new one, with a bigger screen and/or with a higher resolution. In this article, I will answer this question, which we are sure that more than one of you have ever asked yourself.

If you’re thinking about buying a new LCD monitor in today’s technological progress, though, you might be wondering how long they last. At the end of the post, you will find tips for extending the life of your Monitor.

LCD monitors usually have a lifespan of 30,000 to 60,000 hoursof use, which equals 10 to 20 years if the monitor is used for eight hours a day. It has a longer life than the plasma and CRT monitors and is somewhat shorter than that of current LED Monitors.

These numbers may fluctuate slightly, depending on the model and manufacturer, but the fact remains. After this period, the screen brightness drops noticeably, dark areas appear in the corners, and the backlight tint turns yellow.

To ensure your LCD display’s lifespan, you definitely need to adjust the contrast setting (an important factor) for the conditions under which you view your LCD display. Higher light levels and contrast levels affect the life expectancy of the LCD monitor and vice versa.

A LED monitor’s lifespan range between 80,000 to about 120,000 hours. Which is equivalent to about 20 years, if we use 8 hours a day, depending on its materials and manufacturers.

LED monitors that are being sold right now in stores to come with the latest screen materials and technology. Their main advantage if they live longer than LCDs, and CRTs by providing bright and vivid display features that are energy efficient.

A significant factor that influences the life span of a LED monitor is the conditions like Usage, Temperature, and Brightness. The harsherthe use, the higher the temperature and brightness can reduce the lifespan, and the less you can expect a LED to last.

The CRT monitor is old since they were used old technology of cathode-ray rubes that illuminate the corresponding pixels ( typically old backlighting technology) leads to less efficiency, often heavy, bulky, and fragile units. result in a short lifespan.

Today the world is moving with great speed along alongside innovative progress. Also, no one will surprise anyone with a thin LCD monitor or TV. They can be seen in almost any office. Many have already swapped out their old fat CRT TVs for new thin LCD panels. Laptops also have an LCD screen, so this also applies to them.

In fact, there is no exact answer to the lifespan of OLED. However, as per the report and research, the OLED monitor can have a lifespan of 100,000 hours. And it can be last long about 8 – 15 years if you use it 8 hours a day.

There isn’t any certain time period as to when a monitor should be replaced. But, it is worth it when you notice the degradation of the monitor in the form of dead pixels, stuck pixels, dim and greenish image screens.

In most cases, visual abnormality like “Stuttering” and “flickering” is a very common sign of understanding the end of the monitor’s life. When it reaches the end of its life, the screen will disappear even when the power is turned on.

The LCD monitor is turned on and off frequently or used in an extreme temperature environment, the LCD monitor’s backlight life will be significantly shortened. Therefore, if you want to extend the life of the LCD monitor as much as possible, neither turn it on and off every few minutes nor use the LCD monitor in a harsh temperature environment.

You shouldn’t leave the monitor all the time, this significantly affects the expected service life of the monitor. Instead, you can leave your monitor on it goes into sleep mode not just displaying a black screen unless it shortens the life of the monitor as well as consume a lot of electricity

You can spread the knowledge and care for others by sharing the article “How long does a monitor last?” to make aware known of the lifespan of monitors.

The second question that I get from friends or family when discussing plasma TVs is, "Plasmas don"t last as long right, they burn out faster (than other television technologies)? The short answer to this question among top tier brands is, "No, plasma is the equivalent of LCD/LED in lifespan as a technology, though there is variation among brands and models".

One practical example I will cite here is the Panasonic Tau units being used by video rental company, In Motion Pictures at major airports around the country. Most of the earlier Tau models have now been replaced by a newer model, but these plasma displays were used for 5 years and were the first generation of plasma displays to go a considerable distance. In Motion displays images on them from 6AM until 10PM daily (16 hours). By my estimates, these early plasma displays by Panasonic were in use by In Motion for around 30,000 hours or more. They never fail to catch my eye as I pass by in one airport or another to see if they are still in use. If they have lost some of their brightness level its hard to tell. This use equates to 18 years for a home owner that watches 3 hours television per day. So a 100,000 hour lifespan for a plasma TV will mean triple that to 54 years at 3 hours per day.

1) Never leave static images on the unit. Plasma phosphors have become more resilient to burn in and there are many technologies now incorporated to prevent it, but still its better to be safe. Do not leave a static image on the plasma screen for more than 15 minutes during the first month of use. This can cause a ghosting effect which will "wash" out by use over time. Watch the unit in full widescreen format as much as possible to avoid differentiation between the side bars of the unit. While this does not actually decrease the longevity of the phosphors it does cause an annoyance to have to play a gray static image to "erase" the temporary burn in.

2) Use Brightness and Contrast levels that are necessary for viewing - not excessive. In a brightly lit room you may need to view the plasma TV or LCD at a higher contrast and brightness, which will decrease the life of the unit. However, there are memory setting adjustments available on most recent plasma displays that allow the user to choose a memory setting to suit viewing needs. At night, or in a lower light room use lower contrast levels and extend the life. Do not use your plasma or LCD TV on 100% contrast (often designated as the picture option in the menu). In rooms with normal lighting you should not need to use the contrast setting on more than 60% of contrast.

NOTE: Plasma and LCD TV manufacturers routinely ship plasma TVs with the contrast (picture) setting tweaked to 100% of contrast. Therefore, you will need to make this necessary adjustment yourself. See our article titled How to Calibrate your TV.

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.

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).

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.

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.

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.

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.

Now, molecules in liquid crystals move as a reaction to an electric field. Their arrangement changes as a voltage are applied to them. This allows liquid crystals to control polarized light, which, in turn, defines which pixels on a screen will be illuminated or not.

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.

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.

Now, light emitted by your panel’s backlight source enters the first horizontal polarizing filter. It then passes through the liquid crystals. The polarized light vibrates vertically if the liquid crystals are in a twisted state. Hence, these light waves can then pass through the second vertical polarizing filter. The pixel on the screen turns on and is illuminated properly.

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.

Product lifecycle management is the process of taking your product from inception, to design, to manufacturing, to repair/service and then finally to disposal. Implementing an organized product lifecycle management program may be a challenge for companies who run into design and engineering challenges. AGDisplays works together with your teams to support your product’s life from the conception to disposal. At the end of a product’s lifecycle, we can provide EOL display and component alternatives to extend your product’s lifespan.

Once the project gets to AGDisplays, this stage involves gathering and defining the product requirements as defined by customer, company and/or applicable regulations. After specifications are placed, technical parameters are put together. Concept design is created. In the case of building LCD units and peripherals, drawings are gathered, and technical specifications are matched. This is the stage where LCD components are implemented to determine compatibility. The benefit of working with AGDisplays is that we are involved as much as you need us to be. We work from start to finish with your team to bring life to your vision. With over 40+ years of experience in handling, building and repairing displays, our design members are passionate about finding cost effective, compatible and safe components to bring your project to fruition.

Design and development takes place in this stage, and prototype testing can begin. This phase may involve CAD drawings, drawing specifications, specification definition, prototypes and creation of a bill of materials (BOM). If redesigns are necessary, prototype and design will be improved. All hands are on deck when teams work together to collaborate on electrical, mechanical, production, validation and logistical aspects of the project. Project supervisors, Stakeholders, or Managers use these elements to choose a definitive design to realize the final LCD product.

EOL components prompt time and energy to be spent on re-designing of products and extra sourcing charges. LCD Lifecycle Support is a service for customers who have panels in need of component replacement parts. As broken components on your panel go EOL, AGDisplays quickly sources and installs components for increased panel lifespan.

We follow strict supply chain practices and well-maintained databases that lead to ultimate quality and customer satisfaction. Our International Procurement Office in China verifies these resources and quality of the companies we do business with; we have a secure list of trusted vendors with whom we maintain current business practices. Samples are always tested and verified before placing large orders. AGDisplays continues to watch the market for current LCD availability to stay on top of our customer’s needs. We also employ cross-verification methods for alternate components and sourcing.

If you or your company are buying an LCD direct from the LCD manufacturer, it is likely that you will eventually receive an end of life (EOL) notice about the panel(s) you have purchased. This EOL notice is there to let you know that the manufacturer will cease to produce that product part number in the coming years. If you are buying through a distributor, there’s a chance the EOL notification may not reach you. Purchasing the right LCD panel itself is a tedious task. Considering lifespan on top of that may add to the complications of selecting the right display.

The act of selecting the television screen that suits your needs can be difficult enough, but when you consider all the different technologies available out there, it can become downright confusing. If you aren’t into buying a new set every couple of years, you’ll want to take the TV lifespan into consideration. Thankfully, we’re going to cover

Many of us are unaware of the technical aspects regarding televisions, which often leads to blindly purchasing products with a short shelf life. In fact, the more people shift their shopping habits into the online world, many consumers never even see the screen until it’s up in their living rooms. It doesn’t always work out the way they’d hoped.Selecting a set in person will allow you to see the differences in the different technologies, and you won’t find any surprises when you mount it in your home. It can make or break a purchase in regards to how one wants their favorite show or film presented, so knowing what you’re looking for can be incredibly helpful.

In many cases, the location where the television is being used in the household/building can change opinions regarding a purchase. For example, a room full of windows will cause glare on the screen. If the television is at an angle or mounted up high, the picture may not be visible at all. Since these factors have a huge impact on the usage of the televisions, here’s what the most popularscreensoffer:

LED & LCD –LED and LCD televisions are the big players in the market today. They are basically the same backlit setup and each technology has similar perk/setbacks. LED and LCD televisions work excellent in bright rooms, they’ve outsold plasma televisions (and they have taken over the market). They consume less power, they’re thin/light to transport, and they’re bright. However, both LCD and LED televisions fall short when it comes to motion blur (on lower-end models), they sometimes have backlight issues, and they offer limited viewing angles.

Plasma –Although the plasma screen market has been declared “dead”, some still floating around on the market for a decent price. Plasma screens are known for working the best in dark/dimly lit areas, they have no motion blur, and they have the best black coloring in their picture. Unfortunately, plasma screens fall short when it comes to performing in rooms with lots of windows, so this might be a good purchase on the second-hand market for the basement. They’re bulkier than the competition, and they sometimes have image retention issues. Also, they consume more power and can make a buzzing noise.

People generally want to know the lifespan of a TV in years. The average life of LED TVs and LCD sets is typically somewhere from 4 to 7 years of active use. Most of us don’t watch our TVs twenty-four hours a day, so a simple calculation on your watching habits can give you a good estimate. If you watched for 6 hours a day, you could theoretically multiply that lifespan by 4 (6×4=24), giving you 16 to 28 years.

Considering the regular defects and issues that occur over time, LCD and LED televisions basically have the same lifespan. With each of these technologies, the likely failure will come in the form of a worn-out backlight, so decreasing your backlight levels can significantly extend your set’s lifespan. A higher-quality set with a better backlight can also net you a few more years of use.

Plasma screens look great, but are much more sensitive and have little warranty as they have ceased production. The added bulk also means it will be a little tougher to move around if you’re prone to rearranging rooms. If you choose to purchase a plasma screen, chances are it’s a second set, and you shouldn’t expect it to last forever. If longevity is a big factor, opt for newer technology.

If you’re designing a display application or deciding what type of TV to get, you’ll probably have to choose between an OLED or LCD as your display type.

LCDs utilize liquid crystals that produce an image when light is passed through the display. OLED displays generate images by applying electricity to organic materials inside the display.OLED and LCD Main Difference:

These different technological approaches to display technology have big impact in some features including contrast, brightness, viewing angles, lifespan, black levels, image burn-in, and price.

graphics and images visible. This is the reason you’re still able to see light coming through on images that are meant to be dark on an LCD monitor, display, or television.

OLEDs by comparison, deliver a drastically higher contrast by dynamically managing their individual pixels. When an image on an OLED display uses the color black, the pixel shuts off completely and renders a much higher contrast than that of LCDs.OLED vs LCD - Who is better at contrast?

Having a high brightness level is important if your display is going to be used in direct sunlight or somewhere with high ambient brightness. The display"s brightness level isn"t as important if it’s going to be used indoors or in a low light setting.OLED vs LCD - Who is better at Brightness?

Have you ever looked at a screen from an angle and noticed that the images became washed out or shadowy? The further away you get from the “front and center” view, the worse the image appears to be. This is an example of viewing angles in action – the wider the viewing angle, the better the images on screen will appear as you view them from different vantage points.

This means the display is much thinner than LCD displays and their pixels are much closer to the surface of the display, giving them an inherently wider viewing angle.

You’ll often notice images becoming distorted or losing their colors when tilting an LCD or when you view it from different angles. However, many LCDs now include technology to compensate for this – specifically In-Plane Switching (IPS).

LCDs with IPS are significantly brighter than standard LCDs and offer viewing angles that are on-par with OLEDs.OLED vs LCD - Who is better at Viewing Angles?

LCDs have been on the market much longer than OLEDs, so there is more data to support their longevity. On average LCDs have proven to perform for around 60,000 hours (2,500) days of operation.

With most LCDs you can expect about 7 years of consistent performance. Some dimming of the backlight has been observed but it is not significant to the quality of the display.

So depending on how your OLED is used, this can greatly affect its lifespan. An OLED being used to show static images for long periods of time will not have the same longevity as one displaying dynamic, constantly moving images.OLED vs LCD - Which one last longer?

There is not yet a clear winner when it comes to lifespans between LCD and OLED displays. Each have their advantages depending on their use-cases. It’s a tie!

Transmissive displays are dominated by LCDs. Pixels within traditional LCDs operate like shutters, opening and closing to either allow light through or block it altogether. A backlight, which is a glowing LED panel, is behind the LCD to push the light through the pixels. This approach has been used for decades but only allows 7% of the light through, meaning 90%+ is trapped behind the pixels – a complete waste of energy! This gets even worse when the LCD must go outside and be seen in direct sunlight.

To overcome this power drain, LCD manufacturers created the third category of displays – Reflective. They removed the backlight and replaced it with reflective material allowing the display to work by using reflected light from the ambient environment. This reduces power consumption by over 90% compared to Emissive or Transmissive displays! The Kindle e-reader is an example of a reflective display, which looks great in the sun and has a 3+ week battery life.

The challenge with Reflective LCDs is that the industry hasn’t been able to produce a way to light the display in the dark. Reflective LCDs require extremely precise front lighting in order to work and a solution has never been found. Until Azumo…

Azumo’s technology can deliver light from a single LED through their patented optical material. This enables the full promise of LCD 2.0TM — combining all the benefits of a Kindle display (easy to see in the sun, multi-week battery life, easy on the eyes for extended viewing) with all the benefits of an iPad display (full color, video, high resolution).
