One of the industry’s leading oxide panel makers selected Astra Glass as its backplane glass substrate because it has the inherent fidelity to thrive in high-temperature oxide-TFT glass fabrication for immersive high-performance displays.

One of the industry’s leading oxide panel makers selected Astra Glass as its backplane glass substrate because it has the inherent fidelity to thrive in high-temperature oxide-TFT glass fabrication for immersive high-performance displays.

The glass substrate is one of the core layers of TFT LCD. It influences fundamental features of the display in the resolution, light transmittance, thickness, weight, and viewing angle.

The glass substrate is the core component of the TFT LCD and plays a significant role in the upstream of the TFT LCD industry, similar to the silicon wafer in the semiconductor industry.

Since the quality of the glass substrate decides the features of the display in the resolution, light transmittance, thickness, weight, viewing angle, and other important parameters.

The fundamental structure of the TFT LCD is similar to a sandwich, two layers of “bread” (TFT substrate and color filter) sandwiched with “jam” (liquid crystal).

Considering the unique environment in the manufacturing process of TFT-LCD, such as high temperature, high pressure, and environment switching among acidic-neutral-alkaline, the following characteristics of the glass must meet the challenge and quality requirement.

In the manufacturing process, the maximum temperature can reach above 600 ℃, which requires the glass substrate to remain rigid without any sticking even at such a high temperature.

After the etching process, the glass substrate needs to remain with minimal changes, and can’t be left with visible residue and interference with film deposition.

In the process the mother glass is cut into pieces in the required size, with a thickness of only 0.5-0.7mm, the glass needs to have high mechanical strength and elastic modulus >70GPa.

Usually, the size has doubled with each successive generation. From the initial generation 4 (G4) to the current G11, the size of the substrate has grown to 3000*3320mm.

In the global market of glass substrates for TFT-LCD, more than 90% are concentrated in several major manufacturers, such as Corning (America), Asahi Glass (Japan), Nippon Electric Glass (Japan), and AvanStrate (Taiwan).

However, there is still a gap and need for breakthroughs in the glass for high-generation LCD panel production lines and AMOLED alkali-free glass technology. It is hard to achieve high localization in a short time.

(Yicai Global) June 19 -- China National Building Material has built the country"s first production line capable of producing 8.5th-generation TFT-LCD glass substrates, making China one of few nations to master the technology.

The central state-owned firm"s Bengbu Glass Industry Design and Research built the facility after three years of research, Science and Technology Daily reported. The plant aims to obtain certifications that will allow it to manufacture for domestic display makers.

TFT-LCD, or thin-film-transistor liquid-crystal displays, are classified by the size of their glass substrate. Sixth-generation displays are now widely considered out-dated while 8.5th-gen tech is the most advanced. The newer technologies use larger substrates, which are more efficient to make and can be used in larger screens.

Demand for glass substrates in China reached 260 million square meters in 2018, with demand for 8.5th-gen components making up 233 million, according to the China Optics & Optoelectronics Manufacturers Association. But domestic production is only about 40 million square meters and all below 6th-gen. American and Japanese companies mostly dominate the more advanced segment of the market.

Large thin-film transistor liquid crystal display (TFT LCD) panel makers are expected to reduce production of comparatively smaller sized 32-, 40- and 43-inch panels, helping to stabilize panel prices in the third quarter of 2018. In the longer term, however, the oversupply issue still remains, eventually causing older TFT LCD fabs to be restructured, according to IHS Markit (Nasdaq: INFO).

According to the latest AMOLED and LCD Supply Demand & Equipment Tracker by IHS Markit, currently planned new factories will increase large display panel production capacity by 31 percent or 77.7M square meters from 2018 to 2021. However, based on the current demand forecast, there will be about 49 million square meters of capacity in the pipeline more than the market requires in 2021. The supply/demand glut level is expected to continue to increase from 12 percent in 2018 to 23 percent in 2021, remaining well above 10 percent or what is modeled to be a balanced market.

Between 2019 and 2021, there will be a great amount of LCD TV panel capacity built, mainly from generation Gen10.5/11 factories in China, according to IHS Markit.

“Some panel makers may be forced to reduce utilization rates, while some planned capacity may never be built,” said David Hsieh, senior director of displays at IHS Markit. “Furthermore, in the next few years, legacy factory restructuring will likely accelerate. For the TFT LCD industry to return to a balanced supply/demand level, multiple Gen 5, Gen 6 and even Gen 8 factories will likely need to be shut down.”

For example, shutting down half of all Gen 5 and Gen 6 amorphous silicon (a-Si) capacity in Taiwan would remove about 18 million square meters of production capacity, according to IHS Markit. Larger glass substrate capacity, such as Gen 8, will also likely need to be closed to bring the market back toward balance.

“Oversupply is not the end of the crystal cycle. The industry has a long history of dynamically adjusting itself to balance supply and demand,” Hsieh said. “The process may create many challenges for supply chain companies. However, the delayed expansion of new factories, the restructuring of legacy fabs and the potential for faster demand growth spurred by lower panel prices will help the LCD industry to eventually return to equilibrium.”

The top layer of a display module is made of a cover glass which allows the liquid crystal or LED light to shine through and create a visible image. The cover glass acts as a protective layer to the internal display properties. Cover glass can be customized based on the intended display application.

Cover glass can come in a variety of materials and strengths. Some common options for cover glass materials are Gorilla Glass, Dragontrail glass, and soda lime glass. The strength of the material is often correlated with scratch resistance. Additional processes such as heat and chemical strengthening can be used to fortify the cover glass.

The strength of the cover glass is measured by the mineral hardness and determines the scratch resistance of the material. Glass, the standard material used for LCD cover glass, has a hardness rating in the range of 5-7 Mohs. Measures can be taken to increase this rating depending on the required application. Certain medical and industrial applications require a level 7 hardness rating to be considered a safety glass.

LCD cover glass can be customized for any application. Customizations can include strengthening, water proofing, temperature shielding, and optical enhancements. Different materials can be added to the glass substrate to strengthen the material and prevent scratching of the surface. The cover glass can also incorporate special features and printing options. This resource will discuss the options for choosing the best cover glass for your display and application.

As the name implies, cover glass is made of a glass substrate. Depending on the application, cover glass can be strengthened to be more durable. Cover glass can be made of different types of glass substrates which have unique strengths and material properties.

The type of cover glass material used is up to the designer and can be changed for the intended application. Each glass type has different features, advantages, and prices.

Soda Lime glass is the most common material used and has the features of standard glass that you typically see used in windows. This type of glass is strong and cost efficient. The soda lime glass, like other glasses, can range in thickness. The cover glass thickness is specified as the lens width for each display.

Another type of cover glass material is known as Gorilla Glass. Gorilla Glass is a thin, yet strong, light weight material. Gorilla Glass is both scratch resistant and damage resistant. Typical applications for Gorilla Glass include smart watches, kiosks, smart phones, and tablets. Gorilla Glass can also be used for industrial and military applications where durability of the display is essential.

Dragontrail glass, or Dragon glass, is a type of cover glass that is treated with chemicals and heat to improve the strength of the material. The glass material is combined with strengthening particles and heated to a liquid. This process of chemical and heat strengthening makes this type of cover glass scratch proof and highly durable. This type of cover glass is six times as strong as the standard soda lime glass.

Heat tempered glass is a particular process that involves heating the display glass to a liquid at a high temperature. Liquidizing the glass at a high temperature strengthens the glass because the molecules get realigned into a more stable pattern. Heat tempered glass is four times stronger than regular untreated glass.

It is important to note that heat tempered glass is a different type of display glass than heat treated glass. Heat treated glass is at least two times stronger than untreated glass. Heat treated glass and heat tempered glass can both still be broken in the right conditions. The difference is that heat treated glass will brake into large and sharp shards while heat tempered glass will fragment or crack.

Heat tempered glass is typically referred to as safety glass. The heat-treated glass is not considered safety glass by most industry standards. Tempered glass cannot be cut once processed and treated. Heat tempered glass is used in industries such as automotive and industrial for its safety features.

Chemically strengthened glass is strengthened through the process of chemical bonding. The glass is submerged in chemicals at a high heat which enables ions to bond to voids in the glass. The chemical process adds potassium bonds in the place of the original sodium bonds during this chemical reaction. This process strengthens the glass while maintaining the clarity of the glass.

Chemically strengthened glass has the benefit of maintaining optical clarity during the strengthening process and is just as strong as heat tempered glass. This differs from heat treated glass which can cause subtle distortions to the glass surface. The chemically treated glass be cut or drilled after the treatment process while heat treated glass cannot.

The Mohs hardness scale is a way to measure the hardness of a mineral. The hardness defines the scratch resistance of the mineral. This is useful for describing the hardness of different LCD glasses for creating scratch resistant displays. Glass will typically be measured at a hardness level of 5-7 Mohs. Certain cover glass materials will have a higher hardness scale and thus be more scratch resistant.

Soda Lime glass is chemically treated and is a great option for LCDs that do not require extra protection of the glass. A standard soda lime glass for an LCD will have a hardness rated at about 5Mohs. This type of glass is not fragile and will have a standard amount of durability, but it is not rated as an extra strength display glass.

Gorilla Glass is chemically strengthened which provides more damage resistance than standard untreated glass. Gorilla Glass is common in portable electronic devices because it is made of thin and light weight material. Gorilla Glass can also be crack resistant which is ideal for handheld devices. Gorilla Glass has a hardness rating of 7Mohs. The minimum thickness of Gorilla Glass is 0.4 mm.

Dragontrail glass is similar to Gorilla Glass in that it is strengthened through chemical hardening. The harness rating of Dragontrail glass is 7Mohs, which is equivalent to the Gorilla Glass. With this hardness rating, Dragon glass is scratch resistant. The Dragon glass can be thin and durable with a minimum thickness of 1.1mm.

The cover glass of a display is fixed to the LCD with tape or with an OCA bonding material. OCA bonding is an optical clear adhesive that holds the touch panel, cover glass, and LCD together. The adhesive is clear and will dry without smudging the glass of the display.

The OCA bonding is applied in a thin layer of approximately 0.005”-0.008” around the bond line. This type of bonding is good for thin materials such as cover glass and touchscreens. OCA bonding is applied as a sheet to create a uniform bond across the surface of the cover glass.

Special features and optical coatings can be included on the cover glass of the display. Optical coating enhances specific optical characteristics desired by certain applications. Optical coating can also provide moisture protection and dust prevention. There are a broad range of optical coating options available such as the following.:

Optical coatings can increase the durability of the display. The optical coating acts as a protective layer to the internal circuitry and liquid crystal of the display. The coating acts as a sealant for the display to prevent moisture or dust from entering the enclosure. The cover glass can have an extra layer of protection with the use of an optical coating.

The optical coating can add protection against external elements and would be recommended for outdoor display applications. The sealing effect of the optical coating will protect the display from harsh conditions while incorporating the desired visual effects. For example, an outdoor display in full sunlight could greatly benefit from an anti-reflective optical coating on the cover glass.

TFT stands for "thin-film transistor" and it is a type of technology used by LCD (liquid crystal display) screens. Older LCD screens used a type of display called "passive" and they were plagued with ghosting and slow refresh rates. "Active" technology using thin-film transistors makes for brighter and faster screens, so all current color LCD displays use TFT technology.

Plasma is another display technology that competes with LCD. Plasma technology works by exciting pixels with a plasma discharge between two glass plates. It is fairly exotic technology and it can produce exceptionally pleasing pictures. That"s why plasma screens are generally more expensive than LCD.

When choosing between plasma and LCD TVs, you"re actually selecting between two competing technologies, both of which achieve similar features (i.e., ,bright crystal-clear images, super color-filled pictures) and come in similar packages (i.e., 3.5 inch depth flat screen casing). To complicate the decision-making process further, price and size are two previous considerations that are rapidly becoming non-issues as LCD TVs are now being made in larger sizes and at competing prices with plasma.

Whether spread across a flat-panel screen or placed in the heart of a projector, all LCD displays come from the same technological background. A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen (for flat-panel TVs) or one projecting through a small LCD chip (for projection TVs). LCD TVs reproduce colors through a process of subtraction: They block out particular color wavelengths from the spectrum of white light until they"re left with just the right color. And, it"s the intensity of light permitted to pass through this liquid-crystal matrix that enables LCD televisions to display images chock-full of colors-or gradations of them.

TFT Glass has as many TFTs as the number of pixels displayed, while a Color Filter Glass has color filter which generates color. Liquid crystals move according to the difference in voltage between the Color Filter Glass and the TFT Glass. The amount of light supplied by Back Light is determined by the amount of movement of the liquid crystals in such a way as to generate color.

The most common liquid-crystal displays (LCDs) in use today rely on picture elements, or pixels, formed by liquid-crystal (LC) cells that change the polarization direction of light passing through them in response to an electrical voltage.

The segment drive method is used for simple displays, such as those in calculators, while the dot-matrix drive method is used for high-resolution displays, such as those in portable computers and TFT monitors.

To drive the pixels of a dot-matrix LCD, a voltage can be applied at the intersections of specific vertical signal electrodes and specific horizontal scanning electrodes. This method involves driving several pixels at the same time by time-division in a pulse drive. Therefore, it is also called a multiplex, or dynamic, drive method.

In passive-matrix LCDs (PMLCDs) there are no switching devices, and each pixel is addressed for more than one frame time. The effective voltage applied to the LC must average the signal voltage pulses over several frame times, which results in a slow response time of greater than 150 msec and a reduction of the maximum contrast ratio. The addressing of a PMLCD also produces a kind of crosstalk that produces blurred images because non-selected pixels are driven through a secondary signal-voltage path. In active-matrix LCDs (AMLCDs), on the other hand, a switching device and a storage capacitor are integrated at the each cross point of the electrodes.

The active addressing removes the multiplexing limitations by incorporating an active switching element. In contrast to passive-matrix LCDs, AMLCDs have no inherent limitation in the number of scan lines, and they present fewer cross-talk issues. There are many kinds of AMLCD. For their integrated switching devices most use transistors made of deposited thin films, which are therefore called thin-film transistors (TFTs).

An alternative TFT technology, polycrystalline silicon - or polysilicon or p-Si-is costly to produce and especially difficult to fabricate when manufacturing large-area displays.

Nearly all TFT LCDs are made from a-Si because of the technology"s economy and maturity, but the electron mobility of a p-Si TFT is one or two orders of magnitude greater than that of an a-Si TFT.

This makes the p-Si TFT a good candidate for an TFT array containing integrated drivers, which is likely to be an attractive choice for small, high definition displays such as view finders and projection displays.

The TFT-array substrate contains the TFTs, storage capacitors, pixel electrodes, and interconnect wiring. The color filter contains the black matrix and resin film containing three primary-color - red, green, and blue - dyes or pigments. The two glass substrates are assembled with a sealant, the gap between them is maintained by spacers, and LC material is injected into the gap between the substrates. Two sheets of polarizer film are attached to the outer faces of the sandwich formed by the glass substrates. A set of bonding pads are fabricated on each end of the gate and data-signal bus-lines to attach LCD Driver IC (LDI) chips

To reduce the footprint of the LCD module, the drive circuit unit can be placed on the backside of the LCD module by using bent Tape Carrier Packages (TCPs) and a tapered light-guide panel (LGP).

The performance of the TFT LCD is related to the design parameters of the unit pixel, i.e., the channel width W and the channel length L of the TFT, the overlap between TFT electrodes, the sizes of the storage capacitor and pixel electrode, and the space between these elements.

The design parameters associated with the black matrix, the bus-lines, and the routing of the bus lines also set very important performance limits on the LCD.

In a TFT LCD"s unit pixel, the liquid crystal layer on the ITO pixel electrode forms a capacitor whose counter electrode is the common electrode on the color-filter substrate.

Applying a positive pulse of about 20V peak-to-peak to a gate electrode through a gate bus-line turns the TFT on. Clc and Cs are charged and the voltage level on the pixel electrode rises to the signal voltage level (+8 V) applied to the data bus-line.

The voltage on the pixel electrode is subjected to a level shift of DV resulting from a parasitic capacitance between the gate and drain electrodes when the gate voltage turns from the ON to OFF state. After the level shift, this charged state can be maintained as the gate voltage goes to -5 V, at which time the TFT turns off. The main function of the Cs is to maintain the voltage on the pixel electrode until the next signal voltage is applied.

By scanning the gate bus-lines sequentially, and by applying signal voltages to all source bus-lines in a specified sequence, we can address all pixels. One result of all this is that the addressing of an AMLCD is done line by line.

Virtually all AMLCDs are designed to produce gray levels - intermediate brightness levels between the brightest white and the darkest black a unit pixel can generate. There can be either a discrete numbers of levels - such as 8, 16, 64, or 256 - or a continuous gradation of levels, depending on the LDI.

The color filter of a TFT LCD TV consists of three primary colors - red (R), green (G), and blue (B) - which are included on the color-filter substrate.

For its transparency, flat and smooth surface, and excellent heat resistance, this product is used as a substrate for various types of displays such as televisions, personal computers, smart phones, tablet devices, and in-vehicle infotainment. It is an alkali-free aluminosilicate glass that was developed by using the float process.

Recently, screen sizes of LCD TVs have become wider and larger. The glass substrates from AGC enable this trend of larger LCD TV sizes. Glass substrates also play a key role to reproduce clear and beautiful screen images as one of the core components of LCDs.

It is necessary for TFT-LCD glass to meet many strict quality requirements. Unlike window pane glass, glass for TFT-LCDs is not allowed to contain alkalis. This is because alkali-ions contaminate liquid crystal materials and even adversely affect the characteristics of the TFT. Additionally, the glass should not exhibit large sagging even though its thickness is just 0.3 to 0.7 mm and should have excellent heat resistance while assuring dimensional stability even after being heated at high temperature. The glass also should have properties that its composition does not dissolve during the fabrication process using chemicals. "AN100", non-alkali glass developed by us, is the one that has fulfilled those various requirements. Furthermore, since "AN100" does not contain hazardous materials such as arsenic or antimony, it has high reputation for being an environment-friendly glass. Our technologies are supporting the design of thin, large, and environmentally friendly LCD TVs.

An LCD has a layer of liquid crystal sandwiched between two sheets of glass. The most remarkable feature of liquid crystal is its optical characteristics of being both a liquid and a solid. Applying voltage to the layer of liquid crystal causes the orientation of the molecules in the liquid crystal to change relative to each other. This molecule rearrangement controls the light transmission from the backlight; the light passes through color filters of red, blue, and green, and eventually rich images appear on the screen.

Majority of LCDs in wide use now are TFT-LCDs. In a TFT-LCD, a layer of thin film that forms transistors is used as a device that applies voltage to the liquid crystal layer, and those transistors control the voltage supplied to each pixel. The advantages of a TFT-LCD are high resolution and quick response time that enables motion image to be fine and clear.

It is AGC’s display glass substrates, developed using its distinctive precision glass processing technologies, that support these higher resolution TVs.

Smartphones and tablets can now be considered life necessities, and the LCD screen is the most frequently used interface whenever such devices are used. Without the LCD display, it is not possible to send email or view pictures taken by the camera function.

Furthermore, LCDs play an important role in a variety of applications such as in-vehicle displays, e.g. navigation systems and center information displays, and digital signage.

Through production and supply of LCD glass substrates, which is a key material of LCDs, AGC helps create a more convenient and comfortable life through integrating various technologies within the Group.

At present, the price of LCD panels has rebounded. After six months of continuous decline, the price of LCD panels began to stop and rebound at the end of July. According to Displaysearch, the international market research company, LCD panel prices around the world have stopped falling and rebounded since August. In August, the price of 17-inch LCD panels rose 6.6% from $105 in July to $112. The price of the same type of LCD panels fell from $140 in March to $105 in July. At the same time, the price of 15-inch and 19-inch LCD panels has also risen by different margins. According to WitsView"s offer in early August, the price of 17-inch LCD panels rose from $104 in late July to $110, an increase of 5.8%. Analysts believe that this price rebound will continue throughout the third quarter, which will see seasonal growth due to factors such as back-to-school sales in the United States and the completion of inventory digestion in the first half of the year. It is understood that Dell and Hewlett-Packard computer manufacturers began to issue display orders in the third quarter. Display manufacturers Samsung Electronics and Guanjie will increase their production in the third quarter, with the expected growth rates of 25% and 18% respectively.

It seems that the increased demand in the market has led to the release of the production capacity of the display panel production line. According to the domestic TFT-LCD panel manufacturer Beijing Dongfang and Shanghai Radio and Television, the production schedule of the two companies has been scheduled for September. The production capacity may reach the full production target by the end of the year. Beijing Dongfang will produce 85,000 glass substrates per month (its design capacity is 90,000). Prior to that, panel manufacturers had been stuck by falling prices, with Beijing Oriental, Shanghai Radio and Television and even international panel giant LG Philips losing money. According to industry analysts, if the price rebound can continue into the fourth quarter, panel manufacturers such as Beijing Oriental, Shanghai Radio and Television will use the price rebound to reverse the decline.

It is understood that Beijing Oriental"s first quarter financial report shows that the company"s main business income is 2.404 billion yuan, with a loss of 490 million yuan. Beijing Oriental attributed the loss to a drop in the price of 17-inch display TFT-LCD products produced by Beijing TFT-LCD fifth generation production line, a subsidiary of Beijing Oriental Photoelectric Technology Co., Ltd. Beijing Oriental has issued a first half loss announcement in April. In the first quarter of 2006, affected by the off-season operation of TFT-LCD business, the company has suffered a large operating loss, and the TFT-LCD market price downturn continues to this day. Therefore, it is expected that there will still be operating loss in the first half of 2006. In July, LG Philips, the world"s largest LCD producer, reported a loss of 322 billion won ($340 million) in the second quarter of this year and a profit of 41.1 billion won in the same period last year. LG Philips attributed the loss to intense price competition and market demand that did not meet expectations.

CORNING, N.Y., December1, 2015- Corning Incorporated (GLW) announced today that with the support of the Hefei government, Corning will locate a Gen 10.5 glass manufacturing facility adjacent to the BOE Technology Group Co. Ltd. (BOE) plant in the Hefei XinZhan General Pilot Zone in Anhui Province, China.

Actually, the monitors 20 year ago were CRT (Cathode Ray Tube) displays, which requires a large space to run the inner component. And now the screen here in your presence is the LCD (Liquid Crystal Display) screen.

As mentioned above, LCD is the abbreviation of Liquid Crystal Display. It’s a new display technology making use of the optical-electrical characteristic of liquid crystal.

STN LCD: STN is for Super-twisted Nematic. The liquid crystal in STN LCD rotate more angles than that in TN LCD, and have a different electrical feature, allowing STN LCD to display more information. There are many improved version of STN LCD like DSTN LCD (double layer) and CSTN LCD (color). This LCD is used in many early phones, computers and outdoor devices.

TFT LCD: TFT is for Thin Film Transistor. It’s the latest generation of LCD technology and has been applied in all the displaying scenario including electronic devices, motor cars, industrial machines, etc. When you see the word ‘transistor’, you may realize there’s integrated circuits in TFT LCD. That’s correct and the secret that TFT LCD has the advantage of high resolution and full color display.

In a simple way, we can divide TFT LCD into three parts, from bottom to top they are: light system, circuit system and light and color control system.In manufacturing process, we’ll start from inner light and color control system and then stretch out to whole module.

It’s accustomed to divide TFT LCD manufacturing process into three main part: array, cell and module. The former two steps are about the production of light and color control system, which contains TFT, CF (color filter) and LC (liquid crystal), named a cell. And the last step is the assembly of cell, circuit and light system.

In order to enhance productivity, in this step we’ll do a series of procedure on a large glass, which will be cut into smaller pieces in the following step.

First, let me introduce a crucial material, ITO, to you. ITO, abbreviation of Indium tin oxide, has the characteristic of electrical conductivity and optical transparency, as well as can be easily deposited as a thin film. Thus it’s widely used to create circuit on glass.

Now let’s turn to the production of TFT and CF. Here is a common method called PR (photoresist) method. The whole process of PR method will be demonstrated in TFT production.

◇   Use glue to build a boundary for LC on both glass. And on CF glass, apply one more layer of conductive adhesive. This enable LC molecule link to the control circuit.
