• Perform highly diversified duties to install and maintain electrical apparatus on production machines and any other facility equipment (Screen Print, Punch Press, Steel Rule Die, Automated Machines, Turret, Laser Cutting Machines, etc.).

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.

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.

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.

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.

year of the CCFL expected life if you assume a CCFL lifetime in the middle of the range. If you don"t operate your LCD at max brightness then these numbers should be conservative.

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!

If you"re looking for lifespan, CRTs are the way to go. The reason CRTs dim is that the phosphors in the tube slowly escape as they are bombarded by current. Yes, mikef, they dim. But very slowly. However, with a CRT, you"re looking at all kinds of other problems like heat and inconsistency. A flicker is also noticeable in low-end CRTs.

LCDs have a much shorter lifespan, for the same reason as everyone else has said -- The backlight grows dimmer. To answer your question, most modern LCD monitors will be at half brightness after about 60,000 hours, about 5 years for many computer users. But in the past 2 years, their performance has begun to blow away CRT monitors, which were traditionally much better in terms of quality. Also, LCDs are much easier to dispose of.

Of course, everyone is aware of televisions and monitors, but what about the low-level radiation from LCD monitors? Are there reliable studies on this?

What happened to me constantly: whenever I came back to my desktop, the display would switch itself off JUST at the time I came back. Then waking the screen could destroy it very quickly...

What I"m curious about is where you got this idea that LCD monitors even would produce any appreciable amount of low-level radiation. I don"t mean any offense, and I could be wrong without doing any research on it, but it seems rather absurd to me.

I cannot think of any major components in an LCD TV/Monitor that would even produce such radiation. As far as I know, they hardly produce any radiation but that on the visible spectrum, which is obviously necessary.

TFT monitors do not emit radiation at all (compared to CRT monitors). The TCO standard was developed for CRT monitors first, then TCO-99 added TFT / LCD monitors as well.

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.

LCD panels are made of a layer of liquid crystal between two pieces of polarized glass. Liquid crystal can not emit light. Backlights are therefore used to illuminate the display. LCD panels are sleek in design, but typically limited to specific sets of dimensions.

LCD video walls on the other hand take on a tiled approach. This means that screens are jutted against one another. This approach creates bezels or seams and the final dimensions of the wall is directly dependent on the dimensions of the individual screens.

LCD is a more straightforward product and consumers are generally more familiar with LCD. LCD is used for cell phones, computer screens, and most TVs, but is it the best choice for video walls? Ultimately that choice is up to the consumer. LCD is cheaper, but generally less customizable. LCD does not work well for outdoor uses and is generally very limited in terms of size and shape.

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.

The liquid crystal display (LCD) technology has been used in several electronic products over the years. There are more reasons for LCDs to be more endearing than CRTs.
