Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

The world of smartphones has been busy for the past few months. There have been numerous revolutionary launches with groundbreaking innovations that have the capacity to change the course of the smartphone industry. But the most important attribute of a smartphone is the display, which has been the focus for all prominent players in the mobile phone industry this year.

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.

According to LCD (Liquid Crystal Display) technology and LCD materials, mobile phone LCD assemblies can be classified into 2 types: TFT (Thin Flim Transistor) and OLED（Organic Light-Emitting Diode). TFT display needs with backlight, but OLED is light-emitting, each pixel is creating its own light.

For Original iPhone LCD, 5-8 plus and Xr, 11 is TFT, X-13 Pro Max is OLED (except XR and 11). But in mobile phone aftermarket, there are too many different types and different qualities, which makes customers confused.

What is in-cell? What is OGS or " with TP"? What is COF? What is COG? What is OEM? What is FOG? What is Original Change Glass? What is IPS? What is LTPS? What is a-Si?

HTPS with small size, high precision, and high contrast. Most used in magnified display products. Such as projectors, projection TVs, etc. And cannot be used as a mobile phone display, so we don"t talk about it here.

Because the electrons deflect the liquid crystal molecules through the transistor. Electron mobility fundamentally determines the refresh rates of the TFT device. The smaller mobility, the slower transmission of holes and electrons, and the slower response rate. Can"t physically support high refresh rates.

In order to improve the response performance, can increase transistor size to enhance the migration, but this will lead to the extra TFT device that will occupy the display area pixel area. Therefore, the larger unit transistor area, the single-pixel occupy area is smaller(Pixel Aperture Ratio ), resulting in lower brightness.

As we can see electron mobility of a-Si is very low (0.5-1cm2/Vs). But LTPS can deliver a hundred times the mobility than a-Si, and a much higher aperture ratio and PPI is much higher than a-Si resolution.

Compared with LTPS，a-si TFT have those "weakness":a-Si with so much low resolution and low definition. a-Si is 720*1280 with a very blurred display effect.

a-Si with so much bad display performance, but why are there still so many manufacturers producing phone LCDs with a-Si, or why do the customers willing to use a-Si LCD for their phone?

LCDs business has too much competition and wholesalers want to make more profit, they keep pushing suppliers to make LCDs at lower prices. So some of the suppliers start to produce aftermarket phone displays with a-Si to match customers" lower price requirements.

Now in the market a-Si LCDs for iPhone is TFT with TP but not in-cell. Our ZY a-Si will be in-cell not just TFT with TP. ZY a-Si incell for Xr and 11 ready now, please to get more details.

LTPS is an abbreviation for Low-Temperature Polycrystalline silicon. When compared to conventional methods LCD, this form of monitor is speedier and much more incorporated.

Furthermore, rather than enclosing the best positioned, individual row/column controller semiconductors are incorporated onto the glass surface, decreasing the TFT portion as well as the wire between the pixels.

As a result, LTPS LCD units may be brought adjacent together again and attain densities of 200 dpi or higher. It has higher graphic intensities and uses less electricity because it does not light up each pixels separately. Customers might anticipate greater resolution of the image on tablet devices.

This LTPS panel offers a higher graphical fidelity to the viewer, and some people believe it will be more believable. It has higher picture densities and uses less electricity because it does not light up each pixel separately.

The much more essential feature of a smartphones, however, is its display, which has been the focus of all major participants in the mobile phone market early 2019.

Currently, a-Si panels account for a sizable portion of the cell phone screen industry. LTPS is now the gold standard in power supply manufacture and can be discovered while behind majority of high-end LCD and AMOLED displays used in today’s handsets.

It really is based on the common technique to a-Si, but LTPS is manufactured at a greater processing temperature, culminating in a semiconductor with enhanced electrical characteristics. Due to the larger amount of current necessary by this process, LTPS is currently the only technique that truly works with AMOLED.

LTPS also has better electronic conductivity, which indicates whether quickly/easily the electrons can pass across the transistor, with up to 100 percent more maneuverability than a-Si. In instance, this enables significantly quicker swapping between display screens.

The increasing demand for Low Temperature Polysilicon (LTPS) Display is leading firms in the worldwide Low Temperature Polysilicon (LTPS) Market globally to investigate new rivals, innovations, as well as expenditures.

In particular, any use of crystal of silicon in thin-film semiconductors (LTPS-TFT) offers a tremendous potential for huge manufacture of electronic equipment such as flat screen LCD displays or photodetector.

The Low Temperature Polysilicon (LTPS) Display market research also includes detailed information on industry advancement trends, present market characteristics, sourcing raw – materials assessment, and customer requirements.

Samsung Electronics has been one of the growing industries in the global market focusing on better daily technologies to be integrated for major sectors of operations. The Samsung Displays had been exploring producing thin-film transistors (TFT) for use in Samsung Electronics’ Micro LED TVs.

This TFT serves as a switch which toggles its screen’s pixels on and off. For prior Micro LED TVs larger than 100 inches in length, Samsung employed circuit boards (PCB). Nevertheless, the tech behemoth intends to use LTPS TFT for the smaller Micro LED TV versions.

This is attributed to the reason that thinner TV versions will employ even tiny LEDs that would be more densely populated altogether. Any use of LTPS TFT allows for the creation of a microcircuit that really can regulate these tiny LEDs separately. This is tough to achieve using circuits on a standard PCB. This touchscreen will indeed be manufactured by Samsung Displays.

Sony Corporation is growing its development technologies focusing on the LTPS Market of global operability with much higher display systems in operations. Sony has created low-power, comparatively tiny LTPS (Low Temperature Poly Silicon) TFT-LCD screens for mobile devices.

Sony is able to make LTPS TFT-LCDs that utilise approximately 25% lower electricity compared present versions by strengthening drive circuits. Sony also managed to minimise the volume used by control loops by 14%, freeing up more room here on monitor for such monitor screen.

It also intends to manufacture a 1080p Full Active LTPS LCD panel with a 2:1 viewing angle. It has a 6-inch diagonally touchscreen with tiny bezels and Pixel Eyes technology, which allows for far lower black depths than what has been generally connected with LCD displays.

The demand for the best visual experience has grown higher over recent years. Everyone wants the best in the class display to their smartphones to view the high-definition magic their phone provides. This demand for better display has risen recently as big brands like iPhone and Samsung have added some absolutely gorgeous displays to their smartphones.

The major battle begins here. The two competitors of the game are LTPS LCD and AMOLED. These are state of the art displays and people often find themselves comparing these two displays. People are wondering about the result for LTPS vs AMOLED.

LTPS and AMOLED comparison has always been an interesting debate. Potential buyers of smartphones keep comparing the difference between LTPS and AMOLED. There is a complete LTPS and AMOLED comparison below which outlines the difference between these two types:

LTPS stands for Low-Temperature PolySilicon. This type of display provides a faster and more integrated display compared to a standard LCD. The LTPS display provides a better picture quality for the user and some people consider it to be more true to life. It provides larger picture densities and is also lower on power consumption as it does not light up every pixel individually. People can expect a higher picture resolution in their displays.

AMOLED stands for Active Matrix Organic Light Emitting Diode. AMOLED displays are completely different. They use an array of LEDs that help light up every pixel individually, so the only area of the display that is in use, only those pixels light up and the others stay shut. This helps provide a higher contrast to the image with very deep blacks. The display also helps in power consumption as every pixel draws power individually.

There is no actual winner to this debate, just like the console war or the Android vs Apple debate. The choice depends completely on the user and their tastes and preferences. If the users want a better picture resolution in their display, they can go with LTPS LCD and if the user wants a higher contrast picture to their display then they can go with AMOLED. Both displays deteriorate faster than standard LCD screens. Apple is known to use LCD panels in their smartphones and Samsung is known to use AMOLED ones. These are the points that can help the user make an informed decision about which display they would want to go with.

In recent years, with the development of full-screen mobile phones, In-cell LCD screens have gradually been applied to various mobile phone brands. In the In-cell LCD screen assembly, In-cell screens of LTPS In-cell LCD, IPS In-cell LCD, and Retina In-cell LCD have gradually appeared. Let me introduce the characteristics of the three In-cell LCD screens.

LTPS (Low-Temperature Poly-silicon) is a type of polysilicon, which means that the arrangement of molecular structure in a crystal grain is neat and directional, so the electron mobility rate is faster than that of disordered amorphous silicon. Because of the slow electron movement rate of the amorphous silicon a-si, the drive circuit (gate scanning circuit, data circuit) of the panel can only be done on the IC (voltage -10V~15V), and because LTPS has fast electron movement, Therefore, he built the driving circuit (L/S amplifier circuit in the gate direction, switch circuit in the data direction) around the glass substrate, so he only needs to buy low-voltage IC chips (which are cheaper). When LTPS In-cell LCD is applied to the mobile phone screen assembly, it has the features of ultra-thin, lightweight, fast response speed, high resolution, and low power consumption.

IPS screen (In-Plane Switching, plane switching) technology is a liquid crystal panel technology launched by Hitachi in 2001, commonly known as "Super TFT". IPS screen is a technology based on TFT, and its essence is TFT screen. IPS is a film with a layer of resin attached to the surface. The advantage of the IPS screen is that it is oriented into an opaque mode. The electrode with the vertical orientation of the liquid crystal molecules determines how much light is transmitted. The higher the voltage, the more molecules are twisted.

IPS is mainly used on hard screens. The reason why IPS hard screens have a clear and ultra-stable dynamic display effect depends on its innovative horizontal conversion molecular arrangement, which changes the vertical molecular arrangement of VA soft screens, thus having a more robust and stable liquid crystal structure. The reason why it is called an IPS hard screen is to add a hard protective film to the LCD panel to prevent the LCD screen from being damaged by external hard objects. IPS In-cell LCD has fast response speed, large viewing angle, vivid and saturated display color, and stable dynamic high-definition display.

Retina display is also called retina screen, Retina is actually the name of display technology. This technology compresses more pixels onto a single screen to achieve a delicate screen with amazing resolution. Although the resolution of the screen generally appears in the format of "number of pixels x number of pixels", it is the pixel density, that is, PPI, not the number of pixels, that really determines the screen resolution. In addition, in addition to PPI, the distance between the eyes and the screen also determines whether a screen is clear enough to be called "Retina". For smartphones, 326 PPI can be called Retina display. Retina In-cell LCD uses the same technology as LTPS In-cell LCD, but Retina screens have more advantages in PPI.

Mobile phone screen assemblies can be classified according to the type of TFT technology and the arrangement of LCD liquid crystals. LCD and AMOLED are similar in that they both contain TFT glass, and each type of TFT has its advantages and disadvantages.

IGZO, whose performance is one grade lower than LTPS and one grade higher than amorphous silicon a-Si, is suitable for filling the market gap of LTPS in large size, such as tablet computers and computer monitors.

When TFT technology is applied to mobile phone screens, LTPS>IGZO>a-Si. Under the premise of using the same TFT type, IPS>TN, because the VA liquid crystal mode will produce pressing water ripples, it is not suitable for touch screen mobile phones.

As the TFT type, mobile phone screen of IGZO is only Sharp, IGZO does not participate in the ranking. The Samsung AMOLED series does not belong to the scope of LCD liquid crystal display, nor does it participate in the ranking.

With The Advent Of New Display Technologies And The Availability Of Examples Such As IPS LCD, LTPS LCD, And AMOLED‌ In Mobile Phones, The Choice Has Become Difficult For Users.

The world of smartphones has undergone various changes and developments in recent years. We have witnessed the unveiling of innovations in this field, each of which can be considered a revolution. Undoubtedly, one of these innovations is introducing different generations of display panels, which has led to the display of high-quality images and smartphones these days.

Displays act as an interface between the device and users and are now recognized as one of the most vital components of smart devices such as tablets, smartphones, and home computers; Because the result of the operation of the whole device is displayed on this component of the hardware and the transfer of commands is also transferred to the device through this part.

While Samsung, the largest manufacturer of smartphones globally, AMOLED displays are used in its flagship products, LG continues to equip its new products with IPS LCD monitors. Many other companies have another type of display panel called LTPS LCD Are employed. But what is remarkable is the advantages and disadvantages of each of these screens over the other.

Do not use AMOLED displays high-end and expensive Galaxy S and Galaxy Note phones. Does it have an advantage over the screens in LG and Huawei phones? We intend to answer these questions below by examining the types of technologies that can use on screens.

Liquid Crystal display LCDIt is a technology that brings slim and thin screens to the world of smartphones. In a better description, this technology made it possible to produce today’s thin smartphones. LCD monitors have optimal energy consumption and work based on the “light barrier” phenomenon. The liquid crystal in these displays is a kind of backlight that an LED can control or has a reflector provided and uses to expose the image to users.

Screen LCD is divided into two main types; Passive Matrix pages) And Thin Film Transistor pages, which are called TFTAre also known to users. LCD monitors with a passive matrix relative to TFT plates Consume more energy.

Although the use of backlighting in these displays makes them and the smartphones produced by the thicker, this makes the colors and images displayed more natural and clear.

For this reason, it is said that the best viewing angle for viewing images on these screens is the front angle. TFT monitors are now obsolete and have fewer smartphones.

Technologies used in LCD monitors could not maintain the quality of colors and images at wide viewing angles. That’s why another category of LCD monitors under In-Plane SwitchingOr IPSIt was introduced to the market, which solved this problem to a great extent. IPS screens have the ability to change the direction of liquid crystal molecules between glass substrates and arrange them. This significantly improves the viewing angle and the ability to produce color on these displays.

Compared to TFT monitors, IPS LCD monitors consume less energy, and you can also see better images in the sun. The colors produced by these panels are also very natural, but the cost of producing them is far from the cost of producing LCD screens. More than. IPS LCD screens have helped to grow the smartphone market in recent years, and many manufacturers are now using these screens in their products.

LCD screens use uniform (amorphous) silicon material as a color rendering agent; Because this material can be used along with complex electronic boards with high electrical current. This will cause the screen resolution to be slightly limited and the temperature to rise slightly. Later, the replacement of amorphous silicon by polysilicon removed these barriers, and it was possible to increase the resolution and reduce the operating temperature of these displays.

Display manufacturers could also use larger volumes of uniform polysilicon to help electrons move faster, resulting in better resolution and faster refresh rates. With the use of this new material because of the possibility of using cheaper and more expensive substrates, the total cost of production of this type of LCD monitorsDecreased.

These monitors are now titled LCD Low-Temperature PolySilicon Or LTPS LCDAre, compared to LCD monitors’ first generation. They have higher pixel density, better resolution, lower power consumption, and lower operating temperatures.

These panels are therefore called RetinaThey became known that the human eye could not see their pixels. Although Apple measures the pixel density of its displays differently from other companies, Retina displays are Designed to provide users with a density of more than 300 pixels per inch.

screenAMOLEDCompared to LCD monitors, they use completely different technologies, and there is no mention of liquid crystals or other complex structures in them. These displays have an array of small LEDs mounted on Thin Film Transistor modules. Or TFTThey is riding. Organically structured and made using organic materials, these LEDs emit the light needed to display images and colors.

Manufacturers use a combination of filters to minimize the amount of light dissipated by these sources to have outstanding efficiency in these displays. The amount of brightness and color produced by these OLED sources also varies according to the electric pulse.

Given that each LED, Is a separate source from other LEDs, can be cut off by energy, the light emission by each of them can be stopped and thus display a specific image for users.

This structure has the ability to control any OLEDAnd provides the system with pixels; The so-called Active MatrixAnd is currently used in Active Matrix Organic Light Emitting Diode displays AMOLED Is used.

Produce more vivid and natural colors, wider viewing angle, less thickness and weight, and faster response time, including OLED displays’ benefits compared to LCD monitors.

Compared to other technologies used in displays, AMOLED displays can display black colors more accurately and clearly; Because this color is easily accessible by turning off part of the LEDs. More accurate display of black colors makes AMOLED displays, Images with much better contrast or contrast.

Given that OLED displays do not have a backlight, and when producing black color, some of these LEDs are turned off, the energy consumption of these panels is compared to LCDs.It is much more efficient.

But on the other hand, studies show that the lifespan of AMOLED screens is less than LCD panels. Other disadvantages of these displays include losing a significant portion of the image quality when working in bright environments such as sunlight.

Super AMOLED screens are also an upgraded version of OLED screens, and AMOLED is currently manufactured exclusively by Samsung. Unlike AMOLED panels, These displays are designed to integrate touch sensors with OLED cells to fit in.

This way, you will not need to use a separate touch module when using these panels. This causes Super AMOLED displays to have better brightness and image quality and also be able to provide users with better images in bright environments.

In choosing an ideal display panel for smartphones, we must pay more attention to the user’s needs and, by examining them, choose one of the above. If you need a good display with an accurate color display, LCDscreensIt will be the best option for you.

These monitors also have the best lifespan among different types of display panels. LTPS LCD monitors can provide higher image resolution than IPS LCD monitors, and they Spoil sooner.

AMOLED displays also have the best contrast when displaying images among these panels; But compared to LCD monitors over time, they break down faster. That way, if you care more about image quality and resolution, LTPS LCD monitors select AMOLED displays. If you are more interested in contrast, they will be the best choice for you.

In addition, if you spend most of your time outdoors and in the sun, it is better to have a smartphone with an IPS LCD.  Choose; Because these monitors perform better in bright environments. But if you are indoors most of the time, choose a smartphone with an AMOLED display. Or Super AMOLED, Seems wiser.

Japan Display Inc. (JDI) today announced the development of a 21.3-inch high resolution (5 mega-pixel) monochrome TFT display made by low temperature polysilicon (LTPS) technology.

In order to assure high accuracy in medical diagnoses, diagnostic-use displays have recently tended to require higher resolution, higher contrast, excellent grayscale, and brighter and longer lifetime backlights. After many years of supplying medical-use displays using amorphous silicon (a-Si) TFT technologies, JDI has developed a brand new 21.3-inch high resolution (5 mega-pixel) monochrome TFT display incorporating JDI’s most advanced IPS and LTPS technologies to meet the needs for higher performance displays coming about from the medical market.

When a-Si technology is used in high-end medical monitors featuring high brightness (e.g., 2000cd/m2), there are certain side effects that arise from using a more powerful backlight, such as higher cost, bulky heat-sink design, potential noise from fans, higher power consumption, etc. These medical monitors need a better display solution to overcome these problems. By using LTPS technologies, the new display has higher tranmissivity, which contributes to a one-third (1/3rd) power consumption savings compared to the conventional a-Si product. Furthermore, LTPS technologies enable the new display to have fewer driver-ICs and a finer driving circuit layout. Thus, the display’s border can be narrowed by nearly 45%, which helps doctors to more smoothly read and interpret multi-frame radiology and mammography images.

Samples of this new product will be available in the fourth quarter of 2017, and mass production is planned in the second quarter of 2018. JDI plans to further expand its medical-use display lineup by adopting cutting-edge LTPS technologies.

Japan Display Inc. (JDI) is the leading global manufacturer of advanced small- and medium-sized LTPS LCD panels. By leveraging its advanced technologies and the world"s largest LTPS production capacity, JDI provides high resolution, low power consumption and thin displays for smartphones, tablets, automotive electronics, digital cameras, medical equipment and other electronic devices. JDI, which commenced operations in April 2012, was formed through the consolidation of the display panel businesses of Sony, Hitachi and Toshiba. The company"s common stock is traded on the Tokyo Stock Exchange with the securities code number 6740. For more information

Just one year back, the outlook for LTPS LCD (Low Temperature Polycrystalline Silicon Liquid Crystal Display) was filled with fear and uncertainties as smartphone brands such as Samsung, Apple and top China brands shifted their focus to Flexible OLED displays.

LTPS LCD has been the display of choice for most high end products and iPhone models in recent years, but intense interest in flexible OLED display, rave reviews, an expected iPhone shift to OLED and hopes of higher adoption rates created demand uncertainties for LTPS LCDs last year. This year is bringing a change. After slower than expected sales of the iPhone X, the industry’s mood is shifting. Can it bring new opportunities for LTPS LCD?

The success of LTPS LCD panels in high end smartphones, especially iPhones, led many display companies such as JDI, BOE, Tianma, AUO and Sharp, to invest in Gen 6 LTPS LCD fab capacity aggressively in the last few years. The rise of flexible AMOLED and Apple’s decision to adopt that technology has created challenges for LTPS LCD. By the end of 2016, some display suppliers started to delay their expansion plans for LTPS and to focus more on AMOLED displays. Nevertheless, substantial growth of LTPS LCD capacity came in 2017, just when industry interest was waning and global smartphone demand was slowing down. JDI from Japan continued to be the leader but there were substantial capacity growth from China, especially from Tianma.

Last year, the smartphone market also saw the introduction of very high priced phones ($850 to $999) from Samsung and Apple using AMOLED flexible displays. That has helped to increase the average ASP of phones but has not helped the growth in global unit shipments. Smartphone market growth slowed down in 2017 due to saturation in mature markets, a slow upgrade to smartphones from feature phones in emerging markets and longer replacement cycles. LTPS LCD faced fierce competition and oversupply as demand slowed down, leading to aggressive price reductions.

Lowered panel prices have the potential to help in demand creation. Reductions can enable smartphone brands to offer mid-range priced devices ( $500-$600) with higher performance, providing better value to customers. The mid-range segment of the market saw faster growth last year. In spite of over-supply and slower smartphone demand, lower prices boosted LTPS LCD panel unit growth in 2017. The year 2018 can also offer unit growth for LTPS LCD panels due to lower price, increased capabilities and the impact of iPhone X sales.

LTPS LCD has higher electron mobility than other TFT-LCDs, especially a-Si (Amorphous Silicon). Since a large aperture ratio (which is possible because of the smaller transistors, enabled by the better mobility) enables better use of the light, power consumption can be reduced or brightness can be increased. LTPS LCD is suitable for high pixel densities and up to 800 ppi is already possible.

Suppliers such as JDI, AUO and others are making products with advanced in-cell touch technology that enables thin, highly sensitive panels with lower costs. LTPS enables smartphones with a narrow border, resulting in full active bezel-less (or thin bezel) product with a screen-to-body ratio closer to AMOLED-based products from Samsung or Apple. Smartphone brand Asus, showcased a LTPS IPS LCD product at Mobile World Congress (MWC) conference recently, that had a similar screen-to-body ratio as the iPhone X and Samsung Galaxy products. Asus also used an AI chip to reduce power consumption further. Many smartphone brands are coming up with new designs and new, lower priced offerings.

OLED displays can be thinner, lighter, have better color, lower power and better design differentiation especially with flexible displays and plastic substrates. Foldable phones with flexible OLED displays can show truly differentiated design, which will be difficult for LCD to match. As for flexible display, OLED shines and LCD struggles. JDI is planning to introduce LTPS-based plastic full active flex smartphone displays in 2018, where it will be possible to form curved shapes. In the near term, redesigned LTPS LCD has been able to reduce the performance and features gap and even design differentiation gaps with OLED by reinvention. This can also come at a substantially lower cost. With lower price, increased supply LTPS LCD can now bring value differentiation driving demand growth.

Intense interest in flexible OLED display, rave reviews, the expected iPhone X shift to OLED and hope of higher adoption rates created demand uncertainties for LTPS LCDs last year. After lower than expected sales for iPhone X, the industry mood is shifting. There is talk in the industry about Apple reducing flexible AMOLED display procurement in 2018. Now Apple is expected to introduce only one AMOLED model in the second half of this year instead of the original expectation of two models. Samsung Display (the dominant OLED supplier and supplier for iPhone X) is said to have cut utilization rates due to slow demand.

There is industry news about other OLED suppliers delaying production ramp-up. Flexible AMOLED display manufacturing process is very complex and costs are still very high resulting in very high priced smartphones. In the face of a slower, mature smartphone market, these high-end high priced products will not help shipment growth. Most of the smartphone growth in the next few years is expected to come from emerging markets such as India, South East Asia and the rest of the world. In these regions, there is greater need for mid-range and low-end smartphone products. This is where LTPS LCD can come to the rescue until OLED manufacturing yield improves to bring lower costs.

As I said in my Display Daily article almost one year back (May 2017), “OLED Pain = LPTS Gain”, OLED pain can open up a window of opportunity for LTPS.

Most of the smartphone brands have ready shifted their focus to Flexible OLED for their next generation products in 2017. Lower than expected iPhone X sales, combined with Apple and Samsung Display’s decision will force smartphone brands to take a second look at LTPS. Redesigned LTPS LCD-based smartphones have been able to reduce the performance, features and design differentiation gaps with OLED-based products at a lower cost. Issues with flexible OLED’s high costs, lower utilization rates, delayed capacity ramp-up combined with need for lowered priced products will open up new growth opportunities for LTPS LCD. – Sweta Dash

AMOLED and TFT are two types of display technology used in smartphones. AMOLED (active-matrix organic light-emitting diode) displays are made up of tiny organic light-emitting diodes, while TFT (Thin-Film Transistor) displays use inorganic thin-film transistors.

AMOLEDs are made from organic materials that emit light when an electric current is passed through them, while TFTs use a matrix of tiny transistors to control the flow of electricity to the display.

Refresh Rate: Another key difference between AMOLED and TFT displays is the refresh rate. The refresh rate is how often the image on the screen is updated. AMOLED screens have a higher refresh rate than TFT screens, which means that they can display images more quickly and smoothly.

Response Time: The response time is how long it takes for the pixels to change from one colour to another. AMOLED screens have a shorter response time than TFT screens..

Colour Accuracy/Display Quality: AMOLED screens are more accurate when it comes to displaying colours. This is because each pixel on an AMOLED screen emits its own light, which means that the colours are more pure and true to life. TFT screens, on the other hand, use a backlight to illuminate the pixels, which can cause the colours to appear washed out or less vibrant.

Viewing Angle: The viewing angle is the angle at which you can see the screen. AMOLED screens have a wider viewing angle than TFT screens, which means that you can see the screen from more angles without the colours looking distorted.

Power Consumption: One of the main advantages of AMOLED displays is that they consume less power than TFT displays. This is because the pixels on an AMOLED screen only light up when they need to, while the pixels on a TFT screen are always illuminated by the backlight.

Production Cost: AMOLED screens are more expensive to produce than TFT screens. This is because the manufacturing process for AMOLED screens is more complex, and the materials used are more expensive.

Availability: TFT screens are more widely available than AMOLED screens and have been around for longer. They are typically used in a variety of devices, ranging from phones to TVs.

Usage: AMOLED screens are typically used in devices where power consumption is a concern, such as phones and wearable devices. TFT screens are more commonly used in devices where image quality is a higher priority, such as TVs and monitors.

AMOLED and TFT are two different types of display technology. AMOLED displays are typically brighter and more vibrant, but they are more expensive to produce. TFT displays are cheaper to produce, but they are not as bright or power efficient as AMOLED displays.

The display technology that is best for you will depend on your needs and preferences. If you need a screen that is bright and vibrant, then an AMOLED display is a good choice. If you need a screen that is cheaper to produce, then a TFT display is a good choice. However, if you’re worried about image retention, then TFT may be a better option.
