By Lee Kyung-minSamsung Display has decided to close its liquid-crystal display (LCD) business in June, hobbled by a declining global competitive edge due to cheaper products made by its Chinese and Taiwanese counterparts, according to the industry, Sunday. No investment plan details have since been announced.The decision by the display affiliate of Samsung Group came six months sooner than expected, due in large part to rapid losses from falling LCD prices.According to Display Supply Chain Consultants (DSCC), a U.S. market research firm, the average price index of LCD panels, measured against 100 in January 2014, will fall to 36.6 in September of this year. The figure has dropped farther from the record low of 41.5 in April of this year, and 58 percent lower than the record high of 87 in June 2021.Also factored in was Samsung Electronics, the largest buyer of Samsung Display products, partnering with overseas LCD suppliers, including BOE Technology Group, a Chinese electronic components producer and AU Optronics Corp. (AUO), a Taiwanese LCD panel maker.The display affiliate initially sought to close its LCD business in late 2020, but the plan was delayed at the request of its parent company, Samsung Electronics, due to a sudden spike in LCD prices amid the COVID-19 pandemic.Samsung Display will no longer produce LCDs used for large TV screens and focus instead on manufacturing organic light-emitting diode (OLED) and quantum dot (QD) displays. The employees of the LCD businesses are expected to be transferred to the QD businesses.The display affiliate was first formed in 1991, as an LCD business arm under Samsung Electronics. It formally launched in 2012 as Samsung Display and has since merged with three local and Japanese makers of active matrix organic light-emitting diodes (AMOLED), for the production of advanced types of displays.Samsung Display was unavailable for comment.

Compared to Samsung, LG"s LCD factory at Paju felt like a ghost town — despite housing thousands of people on-site. Of course, the sub-zero temperatures at the time probably accounted for that. It was also doubly eerie because the LCD plant is the tallest building visible from North Korea — as it"s so close to the border — and the army base built next door to protect it probably makes it even more of a target!

While televisions of one type or other have been in Australia for over 50 years, they have gone through several changes, with flat panels the latest iteration. LCD TVs have been mainstream products for about four years, but what makes them tick? This year we were fortunate enough to have visited both the Samsung and LG plants in South Korea to get a better understanding of how an LCD TV is made, and what the future holds for the technology.

Samsung is one of the world"s largest manufacturers of LCD panels, and it claims to produce one out of every four in the world. One of Samsung"s largest facilities is in Tangjeong, 80km south of Seoul. Samsung has four different plants on this site, and this is where the joint Sony/Samsung S-LCD plant was first built — and still produces Sony panels to this day. CNET Australia visited Tangjeong recently and while we not only got a squiz at the production lines, we also met with the engineers and designers who helped make them possible.

The Tangjeong factory is a large facility south of Seoul, and produces panels for the five-year-old S-LCD collaboration between Sony and Samsung. As a result of this union, Sony owns part of the production lines on the Tangjeong site — this equates to 50 per cent of the L7-1 line, plus half of the combined L8 (1 and 2) lines. The L8-2 factory has only come online in the last month.

Samsung has begun planning its ninth plant, which will produce its Generation 11 panels (L9), and this will fit in behind the two existing factories. It will be capable of producing much larger panels than the L8 plant with 40, 62 and 72 inches possible.

We got to see one of the L7 (no relation to the LA-based band) lines in operation, after donning the fetching blue shoe covers. Unfortunately, we were unable to take photos inside the LCD factory, as apparently corporate espionage is a big problem. However, we"ll do our best to explain the long corridor with its helpful blue signs and series of LCD panels in various states of undress explaining each part of the process.

There were several different "lines" in each factory — each doing a different sized panel. Apparently it takes three days to convert one line to produce another size, so there is some redundancy built into the system to cover for any downtime.

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.

Samsung Display will shut down its LCD production at the end of June, full six months ahead of the previously announced schedule. Industry insiders revealed competition has been too fierce and Samsung Group wanted to limit losses.

Reports from Display Supply Chain Consultants revealed the price of an LCD is 36.6% of what it used to be in January 2014, the component’s peak production period. This is in no small part due to makers like BOE from China and AU Optronics from Taiwan to join the battle and offer lower prices to clients.

The LCD business was initially scheduled to close in 2020 but with the arrival of COVID-19 and the need of affordable devices for home entertainment (including cheap smartphones and tablets), Samsung decided to postpone this major step.

Samsung Display is reportedly considering advancing its withdrawal from the liquid crystal display (LCD) business from the planned end of 2022 to June 2022.

Samsung Display is producing LCD panels for TVs at L8-2, a large LCD production line at the Asan Campus in South Chungcheong Province. It will make a final decision after a consultation with Samsung Electronics, its largest customer and a sister company.

Samsung Electronics has decided to increase the purchase volume of low-priced LCD panels from China’s BOE, Taiwan’s AOU and Innolux to boost its market share and price competitiveness.

A fall in LCD panel prices also seems to have forced Samsung Display to give up the LCD business. According to market research firm Display Supply Chain Consulting (DSCC), the price of a 32-inch LCD TV panel recorded US$38 (about 45,300 won) in January 2022. This means a 64 percent drop from US$88 in June 2021.

Samsung Display has decided to focus on fostering QD organic light emitting diode (OLED) panels instead of LCDs. Since the end of 2021, the company has been making large QD displays (2200×2500 mm) at the 8.5th-generation production line (Q1) of the Asan Campus. However, its shipments in 2021 were small -- 720,000 units of 55-inch panels and 1.08 million units of 65-inch panels. It accounts for only 3.6 percent of Samsung Electronics’ annual TV shipments, which hit 49.28 million units in 2020. Accordingly, Samsung Display is speeding up its switch to next-generation displays by converting its LCD production line to a QD display production line.

Meanwhile, unlike Samsung Display, LG Display has decided to continue producing LCD TV panels at its Guangzhou plant in China. However, it will also speed up its conversion to OLED displays. It has decided to reduce overall LCD production by converting LCD supplies for information and communication (IT) devices such as laptops and tablet PCs to OLED supplies.
