ips lcd vs pls tft lcd for sale

When it comes to choosing the right panel type of your LCD monitor, the options are seemingly endless. We’ve discussed the differences between AMOLED and LCD displays as well as the different types of touchscreen monitors that are commonly used for various devices and their benefits. Now it’s time to learn about the different features and specifications of PLS and IPS panels so you can decide which one is the most suitable choice for your specific personal or professional applications.

PLS stands for plane to line switching. Also referred to as Super PLS Panel, this technology boasts superior technological advancements such as a multitude of brightness setting options, crystal-clear image quality, and adjustable viewing angles without breaking the bank.

IPS stands for in-plane switching. It’s one of the most commonly used monitors for LCD displays and it consists of two glass panels that hold a layer of liquid crystals in between them. The liquid crystals become animated and perform predetermined actions such as moving in a specific direction or displaying certain colours when they’re charged with an electric current. These actions result in the high-quality images that appear on your television, laptop, or smartphone screen.

Both LCD monitor panel types have their advantages and disadvantages for various types of applications. Finding out how they work will help you determine which one is the best choice for your needs.

As mentioned, IPS LCD monitors contain hundreds of liquid crystals that are situated between two glass sheets in a parallel formation. As electric currents run through the liquid crystals when the screen is turned on, they become animated and move in different directions and backlighting passes through them. This is what produces the crystal-clear and instantaneous images you see on the screen. The excellent viewing angles are the result of the horizontal movements of the liquid crystals inside the panel.

PLS panels for LCD monitors have been on the market for over a decade and have proven to be a worthy adversary for their IPS predecessors. Although the technology is the same for the most part, IPS does offer some minor improvements. The main difference is that IPS panels offer more optimized liquid molecular alignment, which makes for a slightly better viewing experience. Hence, PLS screens offer 15% more brightness than IPS panel types.

From an aesthetic and logistical standpoint, PLS panel types are also thinner than IPS due to the fact that the glass sheets that hold the liquid crystals in place are positioned much lower in the screen configuration.

When it comes to comparing and contrasting the differences between IPS and PLS LCD monitor panel types, the competition is pretty stiff. Both monitors are fairly similar with the exception that PLS is meant to be an improvement on the previous technology. Here are the key factors that should be considered when deciding which one is the best monitor panel for LCD industrial displays.

PLS monitors offer superior viewing angles when compared to IPS displays. Unlike IPS displays, PLS monitors don’t have any noticeable colour distortions and they have significantly lower production costs.

Colour contrast and brightness is a central concern when purchasing a new commercial or industrial display. Whether you’re a gamer or graphic designer, your best option in this regard is to stick to IPS displays. They offer far more consistent image quality, colour contrast, and brightness that’s perfect for applications that rely heavily on high-quality image production.

Unfortunately, PLS and IPS monitors both have a fairly slow response time (the amount of time it takes for liquid crystals to shift from one colour or shade to another). For this reason, neither one is the ideal choice for gaming purposes, but they’re both suitable for graphic design projects that focus more on colour distribution and accuracy than response time.

PLS panel types have been proven to have superior colour distribution and accuracy compared to IPS panel types. PLS displays have a far more expansive colour gamut that’s ideal for users who require the most natural-looking images and colour options.

Backlight bleed occurs when the lights from the back of the screen leak through the edges, which results in uneven lighting or glow. This is a fairly common shortcoming of IPS screens when the brightness is adjusted to a particularly high level and can make for a poor viewing experience. PLS panel types don’t have this problem and offer even lighting regardless of the brightness settings.

The answer is inconclusive. Both IPS and PLS monitor types certainly have their advantages. Although PLS is slightly better in terms of backlighting and faster response times, the margins for improvement are fairly tight. It really just depends on what your preferences are as well as the applications that the monitors are being used for.

If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays.  We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.

These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.

These LCD screens offer vibrant color, high contrast, and clear images at wide viewing angles. At a premium price. This technology is often used in high definition screens such as in gaming or entertainment.

Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.

Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming

Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.

Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.

This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.

PLS (Plane to Line Switching) panel in an IPS-type panel made by Samsung; All IPS-type panels, such as Innolux’s AAS, AUO’s AHVA and LG’s AH-IPS and Nano IPS offer excellent color accuracy and wide viewing angles.

PLS stands for Plane to Line Switching and is produced by Samsung, who claims that a PLS panel offers 10% more brightness, better viewing angles, lower production costs (about 15%), better image quality and the possibility of having flexible panels.

There are several variations of IPS panels, such as AU Optronics‘ AHVA (Advanced Hyper-Viewing Angle) panels. New AHVA panels are usually faster than other IPS panels but don’t have as wide color gamut. However, they can be paired with custom backlights and deliver an exceptional color gamut, such as the Acer XB323UGP with full Adobe RGB color space coverage.

In reality, most people don’t differentiate between IPS, AHVA and PLS since they are pretty much alike, which is why they are categorized under a single entity and simply called ‘IPS.’

Overall, whether a monitor has an IPS, PLS, or AHVA panel shouldn’t be the deciding factor when searching for a new display. You should check each monitor’s color gamut, brightness, response time and other specs to determine which monitor’s panel is better.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

Nostalgia or riddance aside, there are still some valid reasons to use a CRT monitor. When compared to LCD panels, CRT monitors can have higher contrast ratio, very low response time (which leads to non-blurred pictures even with fast movement on screen), and very little input lag, although LCD input lag can be largely negated. The downsides of CRTs are apparent, though: they’re large, heavy, consume more power, produce flicker, can produce audible, high frequency noise (although age plays into whether one can hear them or not), produce slightly distorted images, and produce harmful electromagnetic waves (in the form of x-rays), which requires that toxic materials such as lead and barium must be used as shielding to prevent detrimental health effects. CRT monitors are also notoriously hazardous to repair, given their large, active electrical coils that can measure upwards of 50,000 volts of electricity.

To be clear, many of these issues have been improved upon, but due to the underlying science of LCD TN panels, cannot be completely resolved. In fact, many of these issues -- like uneven backlighting, motion blur, input lag, and dead/stuck pixels -- are inherent issues across all LCD panel types. Poor viewing angles become a more pressing issue with larger displays, since the viewing angle when viewed straight on increases towards the outside of the monitor, thus causing more color distortion. TN panels do have the advantages of lower response times and higher refresh rates than other panel types/CRTs. TN panels are generally from 60Hz to 144Hz, offering substantially greater fluidity of gameplay with higher frequencies.

TN panels provide a good compromise between CRTs and other LCD panels as their traditionally low response rates, input lag, and high refresh rate make them comparable to CRTs for accuracy; TN panels also have the advantages of offering sharper pictures, widescreen output, lower weight, smaller physical dimensions, and higher resolutions compared to CRTs.

Still, compared to other LCD panels, TN panels suffer from poor viewing angles and worse color reproduction. Ultimately, for most gamers playing somewhat competitively to very competitively, TN panels are a good choice, but for those looking for a prettier and improved color experience, another panel type may be worth considering.

IPS (In-Plane Switching) was created to address the shortcomings of TN panels. IPS panels seek to solve TN panels’ issues of poor color reproduction and viewing angles. In this regard, IPS panels have largely succeed. Not only do they offer a higher contrast ratio (superior blacks), high color accuracy (which leads to IPS panels also generally looking less “washed out”), but IPS panels also have very little color shift when changing the viewing angles.

The tradeoff to this is that IPS panels have slower response times, higher production costs, higher power consumption, and lower possible refresh rates. IPS panels have traditionally been 60Hz, although, as with all monitors, they can be overclocked (results will vary). There have been improvements to IPS panels over the years, and slightly different revisions in the form of E-IPS and H-IPS, but ultimately the differences between these versions are inconsequential to gamers and those not involved in graphic design as a job.

Due to their worse response rates and lower possible refresh rates, IPS panels are generally considered to be worse for competitive gameplay and used more often when color is important, such as graphic design. For gamers who don’t play competitively and prefer breathtaking strolls in Skyrim instead of sweeping scrubs in CS:GO, an IPS panel should be a consideration for the next monitor.

PLS (Plane to Line Switching) are quite similar to IPS panels, so much so that they have the same advantages and disadvantages, with a couple extra minor advantages. PLS is produced by Samsung, who claims that compared to IPS panels, PLS panels have better viewing angles, a 10% increase in brightness, 15% decrease in production costs, increased image quality, and allow for flexible panels. Samsung’s PLS panels have been known to overclock well in monitors such as the QNIX 2710 in particular. Overall, PLS is basically Samsung’s version of IPS, as it is very similar in functionality (and even name). AHVA is also very similar to IPS and PLS, and differentiation between them is rare, although it should not be confused with the next panel type.

VA (Vertical Alignment) panels offer a solid medium between TN and IPS panels. VA was created to combine the advantages of IPS and TN panels, and largely did, although they did so with some compromise. That seems to be a theme in the world of monitors.

Compared to IPS panels, VA panels have the advantage of higher possible refresh rates. Although most are currently 60Hz, there are a few that are above 60Hz. VA has more advantages over TN panels than IPS, with better color reproduction, higher maximum brightness, and better viewing angles. VA panels do have the best contrast ratios of all panel types mentioned, but they also have the worst response times of the monitor technologies covered here. This causes blurring in fast-moving pictures and is disadvantageous to gaming.

IPS panels solve the issues of TN panels, with better color reproduction and viewing angles, but do so at the cost of refresh rate and response time. IPS panels are especially useful for those not wanting to play too competitively, but want a beautiful/immersive visual experience. PLS and AHVA are similar enough to IPS to usually not be differentiated.

VA panels provide a good middle ground with better-than-IPS refresh rates and contrast levels, but have worse viewing angles and color production, although generally still better than TN. Response times are VA’s largest downfall, though, being slower than IPS and its variants and TN.

What’s best for you will depend on all of these items. For those wanting to play at a competitive level and who favor FPS or racing games, TN panels are best. Those wanting a more impressive and immersive experience may want an IPS (or similar variant, such as PLS), especially if working on artistic endeavors. Finally, those wanting a general monitor for work might consider a VA panel, although due to their higher response times, they won’t be good for gaming.

Samsung came up with its unique 18:5:9 AMOLED display for the Galaxy S8. LG picked up its old trusted IPS LCD unit for the G6’s display. These display units have been familiar to the usual Indian smartphone buyer. Honor, on the other hand, has just unveiled the new Honor 8 Pro for the Indian market that ships with an LTPS LCD display. This has led to wonder how exactly is this technology different from the existing ones and what benefits does it give Honor to craft its flagship smartphone with. Well, let’s find out.

The LCD technology brought in the era of thin displays to screens, making the smartphone possible in the current world. LCD displays are power efficient and work on the principle of blocking light. The liquid crystal in the display unit uses some kind of a backlight, generally a LED backlight or a reflector, to make the picture visible to the viewer. There are two kinds of LCD units – passive matrix LCD that requires more power and the superior active matrix LCD unit, known to people as Thin Film Transistor (TFT) that draws less power.

The early LCD technology couldn’t maintain the colour for wide angle viewing, which led to the development of the In-Plane Switching (IPS) LCD panel. IPS panel arranges and switches the orientation of the liquid crystal molecules of standard LCD display between the glass substrates. This helps it to enhance viewing angles and improve colour reproduction as well. IPS LCD technology is responsible for accelerating the growth of the smartphone market and is the go-to display technology for prominent manufacturers.

The standard LCD display uses amorphous Silicon as the liquid for the display unit as it can be assembled into complex high-current driver circuits. This though restricts the display resolution and adds to overall device temperatures. Therefore, development of the technology led to replacing the amorphous Silicon with Polycrystalline Silicon, which boosted the screen resolution and maintains low temperatures. The larger and more uniform grains of polysilicon allow faster electron movement, resulting in higher resolution and higher refresh rates. It also was found to be cheaper to manufacture due to lower cost of certain key substrates. Therefore, the Low-Temperature PolySilicon (LTPS) LCD screen helps provide larger pixel densities, lower power consumption that standard LCD and controlled temperature ranges.

The AMOLED display technology is in a completely different league. It doesn’t bother with any liquid mechanism or complex grid structures. The panel uses an array of tiny LEDs placed on TFT modules. These LEDs have an organic construction that directly emits light and minimises its loss by eradicating certain filters. Since LEDs are physically different units, they can be asked to switch on and off as per the requirement of the display to form a picture. This is known as the Active Matrix system. Hence, an Active Matrix Organic Light Emitting Diode (AMOLED) display can produce deeper blacks by switching off individual LED pixels, resulting in high contrast pictures.

The honest answer is that it depends on the requirement of the user. If you want accurate colours from your display while wanting it to retain its vibrancy for a longer period of time, then any of the two LCD screens are the ideal choice. LTPS LCD display can provide higher picture resolution but deteriorates faster than standard IPS LCD display over time.

An AMOLED display will provide high contrast pictures any time but it too has the tendency to deteriorate faster than LCD panels. Therefore, if you are after greater picture quality, choose LTPS LCD or else settle for AMOLED for a vivid contrast picture experience.

On some lower quality LCD screens, you can see bright spots in the middle or on the perimeters of screens. This is caused by uneven light distribution. The downside to using backlights, is that black is never true black, because no matter what, light has to be coming through, so it will never have as dark of a screen as an AMOLED screen. Its comparable to being able to slow a car down to 2 mph versus coming to a complete stop.

OLED vs. IPS LCD is a topic that comes up whenever consumers upgrade to a newer TV or a smartphone. Should you buy a TV that uses an IPS LCD display or should you pick up a TV with an OLED screen? Well, the answer isn’t so straightforward because they both have their advantages and disadvantages. In this article, we will explain how these screen technologies work and which one you should opt for while buying a TV.

IPS LCD (In-Plane Switching Liquid Crystal Display) and OLED (Organic Light-Emitting Diode) are the two most commonly used screen technologies. Older technologies, such as TN (Twisted Nematic) and PLS (Plane-to-Line Switching) displays, have almost disappeared (except in the world of PC monitors and budget laptops) because IPS LCD and OLED are clearly better in almost all aspects. Other technologies such as Mini-LED, MicroLED, and QNED technologies are extremely new and they won’t become mainstream for a few years.

So, when you are finally deciding which TV to buy, the real battle is between OLED and IPS LCD. So where do these stand? Which is better for you? Which one should you pick for your new home theatre? Read on for more information on the OLED vs IPS LCD battle.

IPS LCD displays are perhaps the most common display type days, especially in TVs and laptops. Laptops, entry-level and mid-range smartphones, and most TVs use LCD displays. So, how do IPS displays work? IPS displays use an array of LCD pixels that shift colour as required. However, they don’t emit light on their own. That’s the reason they need a backlight made up of LEDs (Light-Emitting Diodes). The backlight can be arranged in various layouts: towards the edges, spread across the whole display, or separated into different sections.

IPS screens display the black colour by changing the alignment of LCDs so that pixels block the transmission of light, but some light still gets through. That’s the reason IPS LCD displays can’t display true deep black colour. Instead, they display dark grey and there is some ‘backlight bleed’.

OLED displays have traditionally been restricted to high-end devices. Even today, only high-end TVs and laptops feature OLED displays. In the world of smartphones, though, OLED technology has been democratised and even mid-range smartphones these days use OLED displays with high brightness and high refresh rates.

In a nutshell, OLED displays don’t use separate backlight sources. Instead, every pixel can reproduce its own light (also known as self-emissive displays). So, there’s no need for an additional backlight and each pixel can be turned on or off as needed. Since there is no need for a separate backlight plane, OLED displays are much thinner than LCD displays. They also offer a much better contrast ratio and viewing angles. However, the organic material used in OLED pixels tends to “burn” over the years that results in ghosting. Moreover, they can’t be as bright as LCD, Mini-LED, or Micro-LED displays.

We have given you a brief overview of IPS and OLED technologies. But which one is better? And which of these will be right for you? Here’s a list of pros and cons to help you in your purchase decision, where it is for smartphones or TVs.

OLED TVs are slimmer and flexible: As we mentioned earlier, OLED displays don’t need a bulky backlight plane, so OLED TVs are really slim. The next wave of display technologies – foldable and rollable displays – will also be powered by OLED.

IPS LCD TVs offer higher brightness: IPS LCD TVs use a powerful backlight which also lets them get much brighter than their OLED counterparts. This can make for better HDR and even offer a better viewing experience if your TV room gets a lot of sunlight.

IPS TVs suffer from backlight bleed and blooming: This is less of an issue with high-end IPS TVs, but some cheaper models may suffer from glow (bright, greyish areas near the corners of the screen) or backlight bleed (patches or leaks of light, usually around the edges).

OLED TVs can suffer burn-in: OLED displays are at risk of burn-in, a condition in which a static image left on for too long can get permanently ‘burned’ onto the display and may appear like a ghostly dark patch.

OLEDs may get dimmer with age: OLEDs use organic substances which tend to decay over time. So, OLED displays lose brightness with age. It is quite slow and modern OLED TVs are not as affected by this as older OLED TVs, and this really shouldn’t be an issue, but you need to be aware of this.

IPS TVs are much cheaper: OLED is a relatively newer technology and is more expensive to manufacture. Currently, very few companies make OLED display panels. LG Display makes most of the OLED panels found on OLED TVs, while Samsung Display, CSOT, LG Display, and BOE make OLED screens for smartphones and smaller products. Most manufacturers also tend to restrict OLED tech to their largest, most feature-packed range, fueling the perception of OLED being expensive.

Tried and trusted TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen. The pixels themselves do not produce light; instead, the screen uses a backlight for illumination.

So, why use a TFT display? Well, it is a mature technology meaning the manufacturing processes are efficient, yields high and cost much lower than AMOLED.

TFT displays also have a much longer lifespan than AMOLED displays and are available in a far greater range of standard sizes, which can be cut down to fit a space restricted enclosure for a relatively low cost adder.

Super AMOLED (S-AMOLED) and Super LCD (IPS-LCD) are two display types used in different kinds of electronics. The former is an improvement on OLED, while Super LCD is an advanced form of LCD.

All things considered, Super AMOLED is probably the better choice over Super LCD, assuming you have a choice, but it"s not quite as simple as that in every situation. Keep reading for more on how these display technologies differ and how to decide which is best for you.

Super LCD is the same as IPS LCD, which stands forin-plane switching liquid crystal display. It"s the name given to an LCD screen that utilizes in-plane switching (IPS) panels. LCD screens use a backlight to produce light for all the pixels, and each pixel shutter can be turned off to affect its brightness.

There isn"t an easy answer as to which display is better when comparing Super AMOLED and IPS LCD. The two are similar in some ways but different in others, and it often comes down to opinion as to how one performs over the other in real-world scenarios.

For example, one quick consideration is that you should choose S-AMOLED if you prefer deeper blacks and brighter colors because those areas are what makes AMOLED screens stand out. However, you might instead opt for Super LCD if you want sharper images and like to use your device outdoors.

S-AMOLED displays are much better at revealing dark black because each pixel that needs to be black can be true black since the light can be shut off for each pixel. This isn"t true with Super LCD screens since the backlight is still on even if some pixels need to be black, and this can affect the darkness of those areas of the screen.

However, since LCD screens have backlights, it sometimes appears as though the pixels are closer together, producing an overall sharper and more natural effect. AMOLED screens, when compared to LCD, might look over-saturated or unrealistic, and the whites might appear slightly yellow.

When using the screen outdoors in bright light, Super LCD is sometimes said to be easier to use, but S-AMOLED screens have fewer layers of glass and so reflect less light, so there isn"t really a clear-cut answer to how they compare in direct light.

Another consideration when comparing the color quality of a Super LCD screen with a Super AMOLED screen is that the AMOLED display slowly loses its vibrant color and saturation as the organic compounds break down, although this usually takes a very long time and even then might not be noticeable.

Without backlight hardware, and with the added bonus of only one screen carrying the touch and display components, the overall size of an S-AMOLED screen tends to be smaller than that of an IPS LCD screen.

This is one advantage that S-AMOLED displays have when it comes to smartphones in particular, since this technology can make them thinner than those that use IPS LCD.

Since IPS-LCD displays have a backlight that requires more power than a traditional LCD screen, devices that utilize those screens need more power than those that use S-AMOLED, which doesn"t need a backlight.

That said, since each pixel of a Super AMOLED display can be fine-tuned for each color requirement, power consumption can, in some situations, be higher than with Super LCD.

For example, playing a video with lots of black areas on an S-AMOLED display will save power compared to an IPS LCD screen since the pixels can be effectively shut off and then no light needs to be produced. On the other hand, displaying lots of color all day would most likely affect the Super AMOLED battery more than it would the device using the Super LCD screen.

An IPS LCD screen includes a backlight while S-AMOLED screens don"t, but they also have an additional layer that supports touch, whereas Super AMOLED displays have that built right into the screen.

For these reasons and others (like color quality and battery performance), it"s probably safe to say that S-AMOLED screens are more expensive to build, and so devices that use them are also more expensive than their LCD counterparts.
