SEOUL/TOKYO -- Samsung Electronics intends to manufacture liquid crystal display panels through the end of 2022, reversing plans to end production due to an unexpected spike in demand.

But the change in plan also highlights Samsung"s difficulty in developing next-generation displays, and the tech giant"s outlook after the pandemic-driven demand fizzles remains uncertain. Compatriot and rival LG Display has also postponed plans to end production of LCD panels.

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.

For over 20 years Newhaven Display has been one of the most trusted suppliers in the digital display industry. We’ve earned this reputation by providing top quality products, services, and custom design solutions to customers worldwide.

How do we do it? Our agile workforce – from engineers and developers to supply chain experts – work together to respond quickly to a dynamically changing market, customizing solutions to fit each customer’s unique requirements.

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:

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Last week I had the opportunity to tour BOE Technology Group’s Gen 10.5 factory in Hefei, the capital of China’s Anhui Province.This was the third factory, or “fab” that Beijing-based BOE built in Hefei alone, and in terms of capability, it is now the most advanced in the world.BOE has a total of 12 fabs in Beijing, Chongqing, and several other major cities across China; this particular factory was named Fab 9.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

Since most display manufacturing has to be done in a cleanroom and handling the glass requires such precision, the factory is heavily automated.As you watch the glass come in, it is placed into giant cassettes by robot handlers, and the cassettes are moved around throughout the factory.At each step, robots lift a piece of glass out of the cassette, and position it for the processing machines.Some of the machines, like the ones that deposit silicon or ITO, orient the glass vertically, and put them inside an enormous vacuum chamber where all the air is first pumped out before they can go to work.And then they somehow manage to deposit micrometer thin layers that are extremely uniform.It is a miracle that any of this stuff actually works.

It obviously costs a lot to equip and run such a fab.Including all of the specialized production tools, press reports say BOE spent RMB 46 billion (US$6.95 billion). Even though you don’t see a lot of people on the floor, it takes thousands of engineers to keep the place running.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

As part of an exposé that discovered Asanzo Vietnam importing Chinese products and disguising them as locally made merchandise for sale, Tuoi Tre (Youth) newspaper witnessed first-hand the process of assembling China-imported parts into finished products labeled as “made in Vietnam with Japan technology” inside a ‘manufacturing’ plant of the electronics firm.

The factory at Vinh Loc is considered the manufacturing center of Asanzo Vietnam. But there are only assembling activities at the facility, with workers busily making ‘made-in-Vietnam’ TVs and air conditioners from Chinese parts, a ‘manufacturing’ process that also involves removing the ‘made-in-China’ stamps on the main components.

While Asanzo TVs and air conditioners are assembled in Vietnam, the company has been discovered bringing home appliances in the form of finished products from China to sell in the country under the guise of Vietnamese goods.

On April 8, Tuoi Tre reporters witnessed Le Quang, a company headquartered in District 12, and Van Doan Co., located in District 7, clearing customs for many containers of electronics parts shipped from China at Cat Lai port.

In one of the containers imported by Le Quang were six different types of TV components, shipped by Xin Ying Global Co. from the Chinese province of Guangzhou, while 402 LCD panels, shipped by Hong Kong Kangguan Technology, were seen being loaded out of one of the shipments imported by Van Doan.

Le Quang has imported hundreds of thousands of TV components from China in the first four months of this year, according to documents reviewed by Tuoi Tre. Similarly, Van Doan brought to Ho Chi Minh City from China more than 128,000 TV parts, mostly LCD panels in the same period.

Asanzo has said it sold more than 160,000 air conditioners during the peak of this year’s hot season. The company does not manufacture any air-con components in Vietnam, so where the parts were from?

Accordint to Tuoitrenews,  on April 24, Tran Thoan Co. cleared customs for six containers worth of such air conditioner parts as heaters, condensers and compressor motors, shipped by Ningbo Aux Import & Export, at Cat Lai port. The company later imported five more containers of these products.

It is at this facility that the TV and air conditioner components, all imported from China, are assembled into finished products that will be sold as Vietnamese goods manufactured using Japanese technology in the domestic market.

The process starts with placing the circuit board onto the LCD panel, followed by wiring, back panel installing and screwing. The two last steps are checking and stamp labeling.

According to the assembling manual by Asanzo, a worker in charge of the third step in the above process is responsible for placing an Authenticated Stamp Guaranty (ASG) stamp onto every LCD panel to cover the “made in China” text on the original one before installing the back panel.

However, in reality, your correspondents were told to remove the “made in China” stamps rather than overlaying them. The removal method involves applying adhesive tape to the stamp and pull the tape off in the opposite direction. This helps ‘erase’ the “made in China” part on the stamp rather than completely removing the stamp. But that’s enough.

After erasing the stamp, the worker in charge of this step will go on to place the back panel onto the product and proceeds to the next step in the assembly line, no matter how badly torn the original stamp is.

Your correspondents have bought an Asanzo 32” LED TV from a store in Ho Chi Minh City and opened the product to check the LCD panel inside. There, a stamp was found damaged in the same fashion as what your correspondents witnessed at the Vinh Loc factory, meaning no “made in China” was visible from the stamp.

The ‘disguising process’ is much simpler at the Asanzo factory at Tan Binh Industrial Park, where workers only have to assemble parts into finished products such as electric ovens, and place ASG stamps on the products.

According to Vietnamese law, air conditioners imported as finished products are subject to a special consumption tax and a state quality control process. Importing parts for later assembly is a deliberate act of the importer to evade taxes and the required quality check.

Mandy, ETS is obviously a company that you are connected to and this could easily be taken for spam. I think we can make an exception at this time since you are asking a good market research question that may be useful to many.

Having checked out your video, I personally will not use the aftermarket screen as a replacement for my X. It just doesn"t have what I expect for a $1000 USD phone. I recognize that $300 USD for a replacement is hefty but the aftermarket screen does not appear to have the quality that I would expect for my phone.
