tft lcd versus led future pricelist
Reports suggest that Apple is getting closer to implementing MicroLED in its future product releases, including the Apple Watch, with the display technology potentially offering a number of benefits compared to other methods. AppleInsider explains how the current TFT and OLED display technologies work, and how MicroLED differs.
MicroLED shows promise as a display technology, potentially offering power savings and a reduced screen thickness when put beside current-generation display panels. Apple has recognized the potential, and has invested heavily into developing the technology over the last few years, with a view to using it in the company"s future products.
To understand fully how MicroLED can benefit Apple, it is worth understanding how the commonly-used display technologies work in the first place, before examining how different MicroLED really is in a comparison.
The most common display technology used by consumer products today, and the oldest of the technologies examined in this article, TFT"s full name of TFT LCD stands for Thin-film-transistor liquid-crystal display. This technology is extensively used by Apple in its products, found in iPads, iPhones, MacBooks, and iMac lines.
The LCD part relates to the concept of defining small translucent or transparent areas in a thin and flexible liquid crystal-filled panel, like the displays used in calculators. Passing current through the segment changes the molecular properties of the defined segment area, allowing it to switch between being see-through or opaque.
TFT takes this a stage further, by effectively covering an entire panel with a grid of isolated liquid crystal segments, which again can vary between opaque and transparent based on the level of electrical current. In this case, there are far more segments needed to make up the display than with a normal calculator.
Polarizing filters on either side of the TFT display sandwich are used to prevent light from passing through directly, with the liquid crystal reaction of each segment affecting polarized light passing through the first filter to go through the second.
Sometimes these types of display are known as "LED," but this somewhat of a misnomer, as this actually refers to the use of Light Emitting Diodes as a light source. The LED backlight shines light through the various layers making up the TFT LCD.
Displays that use collections of LEDs as individual pixels do exist, but it isn"t usually found in consumer products. LED screens are commonly used for billboards, in attractions, and as a large-scale display for events.
TFT LCD screens continue to be widely used in production for a number of reasons. Manufacturers have spent a long time perfecting the production of the display panels to make it as cheap as possible, while its high usage allows it to benefit from economies of scale.
Used in consumer devices in a similar way to TFT LCD, OLED (Organic Light-Emitting Diode) is a display technology that is similar in the basic concept, but differs considerably in its execution. Again, the idea is for a thin panel to be divided up into segments, with charge applied to each section to alter its molecular properties, but that"s where the techniques diverge.
As the name implies, OLED uses an organic compound film that is put between two electrodes, which are used to provide charge. Instead of the charge changing how light passes through, the current instead causes the emissive electroluminescent layer to emit light, without the need for a rear light source.
These self-emitting pixels gives OLED a considerable advantage over LCD-based systems in a number of areas. Most obviously, by not needing a backlight, OLED panels can be made far thinner than an equivalent LCD-based display, allowing for the production of thinner devices or more internal area for other components, like a larger battery.
The power efficiency of OLED panels can be far greater, as while a TFT screen requires an always-on backlight, the brightness of OLED pixels themselves determine power usage, with a black pixel consuming no power at all. OLED screens are also faster to respond than LCD displays, making them more useful for VR displays, where response time needs to be as rapid as possible.
This also allows OLED to provide superior contrast ratios compared to TFT, as the lack of backlight bleed-through that occurs in TFT simply doesn"t happen in OLED.
OLED also can be produced on plastic substrates instead of glass, allowing it to be used to create flexible displays. While this is currently embodied in curved and other non-flat screens in some devices, it has the potential to be employed in foldable smartphones or rolled up for storage, an area Apple is also allegedly examining.
Despite the advantages, OLED is still lagging behind TFT in terms of adoption. The cost of production is far higher, in part due to the need for extremely clean environments, as a single speck of dust can potentially ruining a display during fabrication.
OLED panels are also affected by the presence of water, both in production and in use. Small amounts of water contacting the organic substrate can cause immediate damage to the display, rendering parts of the screen useless.
So far, Apple"s usage of OLED consists of the premium iPhone X and the Apple Watch. As the cost of production drops down, it is plausible for Apple to use OLED in more future products, providing a better screen for customers to use.
Thought to be the next big thing in display technology, MicroLED basically takes the idea of using LEDs for pixels in a large stadium-style screen and miniaturizes it all.
Using extremely small LEDs, three MicroLEDs are put together to create each pixel, with each subpixel emitting a different color from the usual red, blue, and green selection. As each LED emits light, there is no need for a backlight as used in TFT screens.
MicroLED doesn"t use an organic compound to produce light, making it less susceptible to failure compared to OLED. Just like OLED, it can be applied onto a flexible material, allowing it to be used for curved displays or non-stationary components, like a watch strap, and can result in an extremely thin display panel.
MicroLED offers the same lower power consumption and high contrast ratio benefits as OLED when compared to TFT. However, MicroLED is also capable of producing a far brighter image than OLED, up to 30 times brighter, and is in theory more efficient in converting electricity into light.
As a relatively new and in-development technology, the cost of MicroLED production is extremely high in comparison to the more established OLED and TFT mass production lines, in part due to lower than required yields. Manufacturing equipment vendors have produced hardware for MicroLED production that cuts defects in half and reduces deposition deviance from 3 nanometers down to 1 nanometer, but it is unclear if this is enough to help mass production move forward.
While MicroLED is an attractive proposition for Apple, it is not the only technology under development by the company"s engineers. Apple has previously filed patent applications for a technology described as "Quantum Dot LED and OLED Integration for High Efficiency Displays."
Quantum Dots are photoluminescent particles included in an LED-backed TFT display that can produce brighter and more vibrant colors, with the colors produced depending on their size. While available in current QLED televisions, the technology is only really being used to enhance the backlight, rather than being used to illuminate individual pixels.
The technology in theory can create an even thinner display than OLED, along with a more streamlined manufacturing process. True QD displays are also capable of high pixel densities of up to 1,000ppi, multiple times the density required to be called a Retina-quality display, and based on Apple"s hybrid invention, will also boast the response times of OLED technology.
As is usually the case, Apple does produce a considerable number of patent applications every week that are filed with the US Patent and Trademark Office, and not everything it files will be fully commercialized.
The QD patent application certainly shows Apple is thinking about display technology in multiple ways, and how it can be applied to future devices, but short of getting firm supply chain information or an official announcement from Apple directly, it is difficult to confirm which direction it will be heading.
Apple has been interested in using the technology for some time now, with the first notable sign being its acquisition of LuxVue in May 2014, alongside assorted related patents. A MicroLED specialist, LuxVue was rumored to have been the display producer for the ill-fated Google Glass headset, but was also the holder of assorted patents in the LED display field, including MicroLED.
At the time, the acquisition was thought to be an attempt by Apple to bring part of its display technology development in-house, with suggestions the MicroLED technology would be used in another rumored-at-the-time device, the Apple Watch. A more recent report suggests Apple is working with TSMC to make small panels for a future premium Apple Watch, potentially starting mass production by the end of the year.
Apple has also reportedly set up a secret facility just 15 minutes away from Apple Park, believed to be used for developing MicroLED. The 62,000 square-foot facility is thought to house around 300 engineers on a project named "T159," relating directly to the technology"s development.
The facility is also claimed to be sufficient in size to perform small scale manufacturing of display panels, allowing the company to keep development and testing in-house without involving third-parties. Considering Apple"s previous history in developing technologies before issuing information to manufacturing partners, it is possible that Apple is trying to work out the kinks in production before suppliers even attempt to make MicroLED panels.
Reports from last year also suggest Apple"s investment in MicroLED was a cause for concern for Samsung, LG, and other South Korean suppliers who provide display panels for the company"s products. Owning the process for MicroLED manufacturing could allow Apple to migrate away from its existing display suppliers in the coming years, reducing revenues and profits.
Aside from Apple"s development, there has been little in the way of announcements from other firms for products using the technology that could be bought by consumers in the coming months. The exception is Samsung, Apple"s main rival in the mobile marketplace and a major supplier of display panels, but its usage of MicroLED is not aimed at producing smaller screens.
At CES 2018, Samsung introduced The Wall, a 148-inch TV claimed to be the "world"s first consumer modular MicroLED" television. According to the South Korean electronics giant, The Wall"s modularity meant consumers would be able to customize their television"s size and shape to suit their needs.
The impending use of the technology in a high-priced consumer product could be considered proof that MicroLED display technology is maturing enough for use in devices. If the reports claiming Apple is getting close to mass producing panels is true, the inclusion of MicroLED in the Apple Watch could end up being the first mainstream usage of the technology.
In one corner is LED (light-emitting diode). It’s the most common type of display on the market, however, it might be unfamiliar because there’s slight labelling confusion with LCD (liquid crystal display).
For display purposes the two are the same, and if you see a TV or smartphone that states it has an ‘LED’ screen, it’s an LCD. The LED part just refers to the lighting source, not the display itself.
In a nutshell, LED LCD screens use a backlight to illuminate their pixels, while OLED’s pixels produce their own light. You might hear OLED’s pixels called ‘self-emissive’, while LCD tech is ‘transmissive’.
The light of an OLED display can be controlled on a pixel-by-pixel basis. This sort of dexterity isn’t possible with an LED LCD – but there are drawbacks to this approach, which we’ll come to later.
In cheaper TVs and LCD-screen phones, LED LCD displays tend to use ‘edge lighting’, where LEDs sit to the side of the display, not behind it. The light from these LEDs is fired through a matrix that feeds it through the red, green and blue pixels and into our eyes.
LED LCD screens can go brighter than OLED. That’s a big deal in the TV world, but even more so for smartphones, which are often used outdoors and in bright sunlight.
Take an LCD screen into a darkened room and you may notice that parts of a purely black image aren’t black, because you can still see the backlighting (or edge lighting) showing through.
You’ll often see a contrast ratio quoted in a product’s specification, particularly when it comes to TVs and monitors. This tells you how much brighter a display’s whites are compared to its blacks. A decent LCD screen might have a contrast ratio of 1,000:1, which means the whites are a thousand times brighter than the blacks.
Contrast on an OLED display is far higher. When an OLED screen goes black, its pixels produce no light whatsoever. That means an infinite contrast ratio, although how great it looks will depend on how bright the screen can go. In general, OLED screens are best suited for use in darker rooms, and this is certainly the case where TVs are concerned.
OLED panels enjoy excellent viewing angles, primarily because the technology is so thin, and the pixels are so close to the surface. You can walk around an OLED TV or spread out in different spots in your living room, and you won’t lose out on contrast. For phones, viewing angles are extra important because you don’t tend to hold your hand perfectly parallel to your face.
Viewing angles are generally worse in LCDs, but this varies hugely depending on the display technology used. And there are lots of different kinds of LCD panel.
Perhaps the most basic is twisted nematic (TN). This is the type used in budget computer monitors, cheaper laptops, and very low-cost phones, and it offers poor angled viewing. If you’ve ever noticed that your computer screen looks all shadowy from a certain angle, it’s more than likely it uses a twisted nematic panel.
Thankfully, a lot of LCD devices use IPS panels these days. This stands for ‘in-plane switching’ and it generally provides better colour performance and dramatically improved viewing angles.
IPS is used in most smartphones and tablets, plenty of computer monitors and lots of TVs. It’s important to note that IPS and LED LCD aren’t mutually exclusive; it’s just another bit of jargon to tack on. Beware of the marketing blurb and head straight to the spec sheet.
The latest LCD screens can produce fantastic natural-looking colours. However, as is the case with viewing angles, it depends on the specific technology used.
OLED’s colours have fewer issues with pop and vibrancy, but early OLED TVs and phones had problems reining in colours and keeping them realistic. These days, the situation is better, Panasonic’s flagship OLEDs are used in the grading of Hollywood films.
Where OLED struggles is in colour volume. That is, bright scenes may challenge an OLED panel’s ability to maintain levels of colour saturation. It’s a weakness that LCD-favouring manufacturers enjoy pointing out.
Both have been the subject of further advancements in recent years. For LCD there’s Quantum Dot and Mini LED. The former uses a quantum-dot screen with blue LEDs rather than white LEDs and ‘nanocrystals’ of various sizes to convert light into different colours by altering its wavelength. Several TV manufacturers have jumped onboard Quantum Dot technology, but the most popular has been Samsung’s QLED branded TVs.
Mini LED is another derivation of LED LCD panels, employing smaller-sized LEDs that can emit more light than standard versions, increasing brightness output of the TV. And as they are smaller, more can be fitted into a screen, leading to greater control over brightness and contrast. This type of TV is becoming more popular, though in the UK and Europe it’s still relatively expensive. You can read more about Mini LED and its advantages in our explainer.
OLED, meanwhile, hasn’t stood still either. LG is the biggest manufacturer of large-sized OLED panels and has produced panels branded as evo OLED that are brighter than older versions. It uses a different material for its blue OLED material layer within the panel (deuterium), which can last for longer and can have more electrical current passed through it, increasing the brightness of the screen, and elevating the colour volume (range of colours it can display).
Another development is the eagerly anticipated QD-OLED. This display technology merges Quantum Dot backlights with an OLED panel, increasing the brightness, colour accuracy and volume, while retaining OLED’s perfect blacks, infinite contrast and potentially even wider viewing angles, so viewers can spread out anywhere in a room and see pretty much the same image. Samsung and Sonyare the two companies launching QD-OLED TVs in 2022.
And for smartphones there’s been a move towards AMOLED (Active-Matrix Organic Light Emitting Diode) screens for Android screens, while Apple has moved towards OLED for its smartphones and tried Mini LED with its iPad Pro. Technologies are consistently evolving with Superand Dynamic AMOLED versions available, more performance is being eked out.
While LED LCD has been around for much longer and is cheaper to make, manufacturers are beginning to move away from it, at least in the sense of the ‘standard’ LCD LED displays, opting to explore the likes of Mini LED and Quantum Dot variations.
OLED has gained momentum and become cheaper, with prices dipping well below the £1000 price point. OLED is much better than LED LCD at handling darkness and lighting precision, and offers much wider viewing angles, which is great for when large groups of people are watching TV. Refresh rates and motion processing are also better with OLED though there is the spectre of image retention.
If you’re dealing with a limited budget, whether you’re buying a phone, a monitor, a laptop or a TV, you’ll almost certainly end up with an LCD-based screen. OLED, meanwhile, incurs more of a premium but is getting cheaper, appearing in handheld gaming devices, laptops, some of the best smartphones as well as TVs
Which is better? Even if you eliminate money from the equation, it really comes down to personal taste. Neither OLED nor LCD LED is perfect. Some extol OLED’s skill in handling darkness, and its lighting precision. Others prefer LCD’s ability to go brighter and maintain colours at bright levels.
How do you decide? Stop reading this and go to a shop to check it out for yourself. While a shop floor isn’t the best environment in which to evaluate ultimate picture quality, it will at least provide an opportunity for you to realise your priorities. Whether you choose to side with LCD or OLED, you can take comfort in the fact that both technologies have matured considerably, making this is a safe time to invest.
TFT LCD is a mature technology. OLED is a relatively new display technology, being used in more and more applications. As for Micro LED, it is a new generation technology with very promising future. Followings are the pros and cons of each display technology.
TFT Liquid Crystal Display is widely used these days. Since LCD itself doesn"t emit light. TFT LCD relies on white LED backlight to show content. This is an explanation of how TFT LCD works.
Relatively lower contrast:Light needs to pass through LCD glasses, liquid crystal layer, polarizers and color filters. Over 90% is lost. Also, LCD can not display pure black.
Organic Light-Emitting Diode is built from an electro-luminescent layer that contains organic compounds, which emit light in response to an electric current. There are two types of OLED, Passive Matrix OLED (PMOLED) and Active Matrix OLED (AMOLED). These driving methods are similar to LCD"s. PMOLED is controlled sequentially using a matrix addressing scheme, m + n control signals are required to address a m x n display. AMOLED uses a TFT backplane that can switch individual pixels on and off.
Low power consumption and flexible: OLED doesn"t rely on backlight and consumes less power. OLED is essentially created on plastic film. It is bendable and easy to process.
High contrast and vivid color: OLED emits light itself, can produce very bright image with beautiful color. And because OLED can be turned off, it can produce true black.
Stroboscopic effect: most OLED screen uses PWM dimming technology. Some people who are easy perceive stroboscopic frequency may have sore eyes and tears.
Micro LED, sometimes called μLED is made up of tiny LED, measure less than 100μm. Another way of looking at this is that MicroLEDs are simply traditional LEDs shrunk down and placed into an array.
Replacing organic material with inorganic GaN material eliminates the need of polarizing and encapsulation layer, found in OLED. Micro LED is smaller and thinner, consumes less power.
While the main LED and LCD difference lies in the technology the TV uses to project visuals on screen, each of the two technologies responds to projections and video in a different way.
An LED TV, owing to the technology it uses, flaunts a thinner screen with sharper edges. On the other hand, the two-layer display technology adds bulk to an LCD TV.
Backlight is an important difference between LCD and LED TVs. An LED TV backlight comes in two ways: edge lighting and full array lighting. Unlike an LCD TV that uses CCFL for backlight, most LED TVs use ‘light guides’ to project pictures on the screen. For example: the latest LED Sony TV and LG TV use the edge lit with local dimming technology to present bright visuals.
When comparing LCD vs LED on the parameter of brightness, an LED TV stands out as a winner. This is because it appoints an individual dimming and backlighting system, which in comparison to LCD, makes your projections more defined, authentic, and closer to reality.
LED TVs have superior black levels and employ dynamic contrast mechanisms as compared to LCDs. Colour precision is also more defined in case of LED TV.
LCDs project clear pictures for up to 165 degrees, but projections tend to distort beyond this point. However, LED TVs are equipped to offer you better clarity at all viewing angles.
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%.
Owing to the technology on offer, the price of LED TVs is higher as compared to LCD TVs. For instance, to buy an LED TV that is HD Ready, you will have to spend a minimum of Rs. 10,000 and the price will go up with an increase in screen size and technology. Smart TVs, for instance, come with a higher price tag.
The best part about an LED TV is that it can perfectly fit your space, however limited or expansive it may be, courtesy its versatile size and thickness. You can buy LCDs ranging between 13 and 57 inches in size and LEDs of up to 90 inches, based on the available space.
The most common type of LCD TVs today is the flat screen; however, you can also get front projection LCDs that project an image onto a flat screen. When it comes to LEDs, the most common type is the Edge LED TV that spreads the light uniformly behind the screen. You can also find Dynamic RGB LEDs, which offer dimmer or brighter projections on certain areas, and Full-array LEDs that do not offer dimming or brightening of an individual area.
With this comparison, you must have realised that LED TVs are better than LCDs. However, when choosing a TV, understand your viewing requirement first, then choose what suits you the best. If playing games or watching films in high definition is your passion, then choose LED TVs over LCDs.
In the time to come, OLED technology is going to dominate the LED TV market. While some brands like Sony have already launched exceptional OLED TVs, more is yet to come. Unfortunately, LCD TVs will slowly vanish from the market owing to their cumbersome make and limited features.
In this context, the global consumer electronics market where LCD is located is affected in many ways. First of all, due to the pull of the economy, purchasing power can still remain strong, especially the commercial and education market demand in the North American market will remain relatively strong. There is also a downside. Due to the promotion of consumer demand in the early stage, especially the resident assistance policy, the phenomenon of demand overdraft has already occurred, and consumer demand will be affected by demand overdraft, and the future trend is not optimistic.
From the perspective of LCD panel shipment performance, according to the shipment performance of the four major mainstream LCD applications such as TV, Monitor, Notebook, and Mobile in 2021, it shows the characteristics of “weak at both ends and strong in the middle”. Looking forward to 2022, the shipments of LCD for mobile phones are expected to remain relatively stable, while the shipments of large-size LCD panel applications such as Notebook, Monitor, and TV have experienced a year-on-year decline of varying degrees due to the fading dividends of the epidemic, but the shipment area of large-size panels has performed significantly better than performance in terms of shipments. From the perspective of notebook LCD shipment performance, it is expected that the shipment area in 2022 will decrease by 3.8% year on year, and the decline in the area is lower than the decline in quantity. The shipment area of Monitor and TV panels can still maintain relatively good growth. The area growth brought about by large size is still the most effective way for LCD panel manufacturers to reduce production capacity.
Among large-size LCD applications, TV panels are the absolute main force in reducing production capacity. From the perspective of the shipment area in the first three quarters of 2021, TV panel shipments account for more than 70% of all application panel shipments. In the future, it is expected that the global display panel market will still exhibit cyclical fluctuations, and TV panels will still undertake the important task of reducing production capacity. Since the second half of 2020, the LCD panel price, especially the increase in the price of large-size panels, has driven the profitability of LCD manufacturers to improve significantly. At present, manufacturers are still in a period of high profitability. Of course, it cannot be ignored that the price of large-size panels continues to decline. It is expected to face profit challenges in 2022. The profitability of LCD manufacturers will face differentiation, and some manufacturers may fall into loss expectations.
From the perspective of production capacity investment, investment in the global display panel market will show two characteristics: first, the pace of investment in new LCD lines by panel manufacturers has slowed down significantly; second, investment in OLED will remain active, but the direction of investment in OLED will change. Significant changes occurred.
First of all, it turns out that panel manufacturers are very active in investing in small-sized OLEDs, especially flexible OLEDs. The future investment strategy will shift from small-sized to medium-to-large-sized, and from low-generation (6th generation) to mid-to-high-generation lines. According to statistics, it is expected that three 8.5-generation OLED production lines will usher in mass production by 2025. At the same time, the change of OLED investment direction will also change from the original Flexible OLED to multi-technology, WOLED will continue to expand production, and QD-OLED production capacity will continue to increase. At present, panel manufacturers represented by Korean factories(SAMSUNG & LG) are very active in investing in Hybrid OLED. Statistics show that it is expected that the global OLED display panel production area will continue to grow by more than 10% by 2025, especially with the gradual mass production of high-generation OLED production lines. It is expected that QD-OLED and Hybrid OLED will play an increasingly important role in the global OLED panel market from 2023.
Although the investment pace of panel manufacturers in LCD panels has slowed down, Chinese panel manufacturers still maintain a positive strategy for the expansion of existing production lines. The expansion of production will also drive the continuous growth of the supply area of LCD panels. According to statistics, it is expected that the global display panel production capacity will reach a high-speed growth of 12% year-on-year in 2022, and the overall production capacity growth rate will reach the largest increase since 2013. Therefore, it can be predicted that the pressure on panel manufacturers to reduce production capacity in 2022 should not be underestimated.
How will the global display industry pattern evolve? In 2021, an obvious “one superpower, many strong” competition pattern has been formed. BOE maintains a very clear leading edge in all applications. The market share of each application market has exceeded 20% in terms of the number of shipments and shipment area, and the leading edge is obvious. There is an imbalance in other panel manufacturers. Most manufacturers have certain competitive advantages in some fields, but the overall competitiveness is still not strong. For example, TCL (CSOT) and HKC can maintain a market share of about 15% in the TV panel market. It cannot be ignored that the performance of the IT application panel and the Mobile application panel is still relatively weak. Under this competitive landscape, it is expected that Chinese panel manufacturers including TCL and HKC will adopt active strategies for LCD applications other than TV in the future, including the expansion of existing production lines, and strive for opportunities to increase investment in new production lines.
Let’s look at the evolution of the competitive landscape of OLED. At present, OLED technology, especially in mobile phone applications, has gradually gained popularity. According to statistics, the overall proportion of OLED in the global smartphone shipments will reach nearly 40% in 2021, and will continue to grow in the future. The proportion will be close to 50% before 2025. In particular, the penetration rate of flexible OLEDs in mobile phone applications has shown a trend of significant growth. In 2021, the overall proportion will reach 22%, and it is expected that this proportion will continue to increase to 33% by 2023. From the perspective of panel makers, currently, flexible OLEDs are still dominated by Korean factories. Samsung Display will account for more than 50% of the entire global flexible OLED market in 2021. Although it will shrink due to the increase in production capacity from Chinese panel makers, it will also shrink in 2022. But it will still maintain a share of about 50% in 2022. Chinese panel manufacturers are particularly active in capacity expansion, especially BOE, TCL, and Visionox are all actively deploying flexible OLEDs. It is expected that the market share in 2022 will increase significantly compared to 2021.
The first is the upstream material supply chain. The shortage of upstream materials, especially semiconductor materials, has accelerated the restructuring of the upstream supply chain in the past year or so. Panel manufacturers pay more attention to the risk management of the supply chain. Chinese panel manufacturers will continue to expand and cooperate with local manufacturers. BOE is constantly introducing more local partners, and will continue to strengthen its thinking on display semiconductor materials in the future; TCL will also introduce more local supply chains to prevent supply chain risks and actively seek win-win cooperation with upstream manufacturers situation. From the downstream point of view, the diversified layout of the supply chain will become an obvious trend to prevent supply chain risks and achieve the purpose of supply chain balance.
In 2022, the overall demand for TV panels is not optimistic, but there are structural opportunities. The famous brand’s overall stocking strategy tends to be conservative, which affects the number of panel shipments to maintain a year-on-year downward trend. However, thanks to the accelerated promotion of large-scale size, the shipment area continues to increase. At the same time, from the perspective of subdivisions, although the performance of the 8K LCD market is mediocre, the shipment scale of OLED panels and high refresh rate panels will expand significantly, which is worth looking forward to. Especially in 2022, Samsung Electronics and other leading TV manufacturers will join the OLED camp, and Samsung Electronics will also carry out active and strategic cooperation with LGD in the WOLED field, which is expected to drive the global OLED TV and OLED TV panel shipments to continue to expand. According to statistics, the number of OLED TV panel shipments in 2021 will reach 7.6 million units, a year-on-year increase of 72.2%. It is estimated that the global OLED TV panel shipment scale will exceed 10 million units in 2022, with a year-on-year growth rate of 47.1%.
In 2022, the overall LCD TV supply and demand environment will be loose. In the first quarter, there will be excess supply in the off-season, and panel prices will continue to decline, but the decline will gradually narrow. In the second quarter, supply and demand will tend to balance, and panel prices are expected to stabilize.
The gradual increase in the production capacity of displayers, coupled with the growth of LCD panel manufacturers in monitor display supply planning, is expected to maintain a growth trend in the supply trend of display panels in 2022. Combined with the changes in the demand structure, the overall supply and demand situation in 2022 will be relatively loose. Therefore, it will lead to a continuous decline in the cost of displayer panels in at least the first half of 2022. Affected by the demand structure, the upgrade momentum of the monitor market will slow down, but there are still representative markets with growth potential, such as the Gaming monitor, which is driven by the dual engines of 240Hz and OLED, and the Gaming displayer market in 2022 can still maintain positive growth; Another example is Ultrawide displayer. Under the influence of the active strategy of suppliers, the joint force of the entire supply chain will promote the positive growth of the Ultrawide displayer market in 2022; the Curved surface LCD market will enter a state of slow growth, with the hope that the market can find new growth momentum.
With the growth of Notebook LCD production capacity, especially the mid-to-high-end production capacity, the supply shortage of Notebooks will be significantly eased in 2022. From the purchasing point of view, there is a certain risk of saturation in the notebook market in 2022. Therefore, in 2022, we should be alert to the risk of oversupply. In this process, there is still a positive side, such as the accelerated trend of large-scale LCD size and structural upgrading, etc. Accelerating this change will have a better impact on the market.
By sorting out the development potential of 5 core technologies such as Gaming, OLED, LTPS, Oxide, and Mini-LED in LCD panel applications for Notebook, we believe that on the whole, in 2022, the situation of the coexistence of multiple new notebook technologies and development and competition will become more obvious. In the process, the technologies with the greatest development potential in 2022 are Gaming, OLED, and LTPS; Oxide has slowed down in the past 2 years due to the influence of certain factors, but we believe that after 2023, Oxide will usher in new. The development of Mini-LED is limited in the future due to the high cost.
In 2021, under the panel supply pattern with the participation of BOE and Samsung Display, and more players, the competition in the smartphone panel market will show a hot trend, and the integration of the industry chain will also accelerate. In terms of technology types, the trend of the proportion of each technology type shows a differentiation phenomenon. Among them, the demand for flexible OLED continues to grow driven by the supply side. It is estimated that by 2025, the market share of flexible OLED smartphone panels will reach about 33%; In addition to the growth of flexible OLEDs, the penetration rates of a-Si(IPS), LTPS, rigid OLEDs, etc. are all in a downward trend, forming a “hamburger” shape market.
In recent years, smartphone terminal brands have maintained high inventory levels. As of the end of 2021, there will still be a lot of inventory in some technology-specific panels, but the demand for flexible OLED panels for high-end brands in 2022 will still show a growing trend. The structure of the supply chain is shifting to mainland China. At the same time, flexible OLED panel factories in mainland China will also grow rapidly, and the customer structure will be further enriched.
In terms of technology, the development trend of the in-vehicle displays toward large size and high resolution is also very clear. At the same time, in the future, there will be more and more car brands and models equipped with OLED. However, considering that it is more difficult to apply vehicle display technology, it is estimated that by 2025, the shipment of OLED vehicle displays will be about 3 million pcs. Mini-LED backlight products have been mass-produced in other applications, but currently, there are relatively few applications in the automotive field. There are already models released, and mass production is expected to be achieved in 2022. Mini-LED backlight is an upgrade of a-Si LCD, and each panel factory has a layout. Therefore, we expect that by 2025, the shipment of Mini-LED backlight vehicle display products will reach about 4 million pieces, with rapid growth.
In summary, the LCD applications and market in 2022 will see significant technological advances alongside the challenges. As an LCD supplier and manufacturer, VISLCD is optimistic about the future of LCD development and will maintain stable shipments and reasonable market prices, regardless of whether the market is hot or the demand is slow so that we can move forward together with our customers.
There are three main technologies used for projection – DLP, LCD and LED. DLP (Digital Light Processing) uses a chip made of tiny microscopic mirrors and a spinning colour wheel to create an image. DLP projectors deliver sharp images, don"t need any filters, have a better response time as well as 3D capabilities. The effective lamp life of a DLP projector is only 2000-5000 hours and some people see colour ghosting/banding in some scenes. On the other hand, LCD projectors use liquid crystal displays, have no moving parts and thus are generally less expensive. If you are on a budget a single chip LCD projector is ideal while 3-chip LCDs offer better colour saturation, lower noise levels and work better for movies. However, LCDs require constant filter maintenance and output less contrast. The LEDs in LED projectors have a lifespan of over 20,000 hours. They deliver better colours, have lower power consumption and virtually zero maintenance costs. Also, LED projectors are smaller and generate less heat. Do keep in mind that LED projectors have limited brightness compared to LCD or DLP so they are not recommended if your room has a lot of ambient light.
Tip: Some high-end projectors come with a feature called lens-shift. This is a physical rail that adjusts the lens up/down & sideways to move the image around. Obviously, this offers a lot more flexibility with regards to projector placement.
Pico projectors use LEDs as the light source due to which they can be extremely compact in size. Pico projectors can fit in your palm or be integrated into various devices like mobile phones (Samsung Galaxy Beam), tablets (Lenovo Yoga Tab 3), computers, and even digital cameras (Nikon S1000pj). While these projectors do not offer very high resolution or brightness, they are good enough to use in a small, dark room. You can get a 60-inch screen and you can connect multiple devices like smartphones, gaming consoles and laptops. Moreover, the portable size enables manufacturers to add internal storage as well as rechargeable battery in devices that weight less than 200 grams.
Some movies are shot in widescreen (16:9 or wider) – but to display them in standard width video formats (4:3 or square), you will see black bars above and below the display area. This is called letterboxing
A 3 colour LCD system uses individual LCDs for red, green and blue. The light from each LCD is combined using a prism to create a final image. It usually offers better quality than single chip LCD or DLP designs.
Two of the main contenders for display technologies that are widely available are AMOLED and LCD. Here in this article, we will be comprising AMOLED vs LCD and find out which one is better for you.
Starting with the AMOLED first, it is a part of the OLED display technology but with some more advanced features. To completely know about it must understand its all three components. The first one is LED, “Light Emitting Diode”. Then we have “O” which stands for organic and makes the OLED.
It actually means that organic material is placed with two conductors in each LED, which helps to produce the light. And the “AM” in AMOLED means Active Matrix, it has the capability to increase the quality of a pixel.
The AMOLED display is similar to the OLED in various factors like high brightness and sharpness, better battery life, colour reproduction, etc. AMOLED display also has a thin film transistor, “TFT” that is attached to each LED with a capacitor.
TFT helps to operate all the pixels in an AMOLED display. This display might have a lot of positives but there are a few negatives too let’s point both of them out.
It comes with individual LEDs so, the pixels can be turned on and off individually. This will show you true black colours, as the pixels on the black part of the image will be turned off.
Low outdoor visibility, usually the AMOLED Displays are quote not bright in direct sunlight and outdoor readability could be a problem for some devices but average screen brightness.
The LCD stands for “Liquid Crystal Display”, and this display produces colours a lot differently than AMOLED. LCD display uses a dedicated backlight for the light source rather than using individual LED components.
The LCD displays function pretty simply, a series of thin films, transparent mirrors, and some white LED lights that distributes lights across the back of the display.
As we have mentioned, an LCD display always requires a backlight and also a colour filter. The backlight must have to pass through a thin film transistor matrix and a polarizer. So, when you see it, the whole screen will be lit and only a fraction of light gets through. This is the key difference comparing AMOLED vs LCD and this is what differentiates these two display technologies.
The LCD displays are cheaper compared to the AMOLED as there is only one source of light which makes it easier to produce. Most budget smartphones also use LCD displays.
LCD displays have bright whites, the backlight emits lots of light through pixels which makes it easy to read in outdoors. It also shows the “Accurate True to Life” colours, which means it has the colours that reflect the objects of the real world more accurately than others.
LCDs also offer the best viewing angle. Although it may depend on the smartphone you have. But most high-quality LCD displays support great viewing angles without any colour distortion or colour shifting.
The LCD displays can never show the deep blacks like AMOLED. Due to the single backlight, it always has to illuminate the screen making it impossible to show the deep blacks.
The LCDs are also thicker than other displays because of the backlight as it needs more volume. So, LCD smartphones are mostly thicker than AMOLED ones.
Let’s start with the pricing. Most AMOLED display smartphones always cost more than an LCD smartphone. Although the trend is changing a bit. But still, if you want to get a good quality AMOLED display you have to go for the flagship devices.
The colors are also very sharp and vibrant with the AMOLED displays. And they look much better than any LCD display. The brightness is something where LCDs stood ahead of the AMOLED display. So using an LCD display outdoors gives much better results.
The last thing is battery consumption, and there is no one near the AMOLED displays in terms of battery. As of now, all smartphones feature a Dark Mode and most of the apps and UI are dark black with a black background. This dark UI on smartphones doesn’t require any other light, it gives the AMOLED displays a boost in battery performance.
Looking at all these factors and comparing AMOLED vs LCD displays, the AMOLED displays are certainly better than the LCDs. Also, the big display OEMs, like Samsung and LG are focusing more the OLED technologies for their future projects. So, it makes sense to look out for AMOLED displays. That being said, if we see further enhancements in the LCD technology in terms of battery efficiency and more, there is no point to cancel them at this moment.
The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.
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.
