lcd panel material manufacturer

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.

Our lasers are proven in a wide range of FPD applications including glass cutting/drilling, ITO patterning, repair and marking. We deliver a broad portfolio of highly reliable, cost-effective lasers for 24/7 flat panel manufacturing backed by our industry-leading global support organization.

The Spirit 1030-100-SHG laser system operating at wavelengths of 515 and 1030 nm has been used for cutting 75 μm thick ribbons of PI and PET plastics, typically used for flexible OLED displays. Figure 1 shows microscope images of PI and PET plastics machined using the Spirit 1030-100-SHG laser. Cutting speeds exceeding 1 m/s for both plastics were achieved when operating the laser at 100 W average power at 1030 nm. It was also possible to achieve high machining quality with minimal thermal damage (HAZ < 50 .m). The demonstrated cutting speed and quality meets the requirements of OLED display manufacturers.. Please see Newport.com for additional information on Flat Panel Display Manufacturing.

As the flat panel display market moves from liquid crystal display (LCD) to organic light emitting diode (OLED) display technology, laser structuring and cutting of heterogeneous materials (comprised of multiple organic material films) with high quality and accuracy is needed. Within OLED technology, substrate material is changing from glass to flexible plastics to create lighter, thinner and more durable displays. See Flexible OLED Manufacturing with High 42 Power Femtosecond Laser for additional information.

Manufacturing of flexible organic light-emitting diode (OLED) displays is critical for next-generation consumer electronic devices, including foldable phones. OLED displays are comprised of multiple layers of polymer materials, including polyimide, polyethylene terephthalate (PET) and cyclo olefin polymer (COP). These materials are transparent to infrared and visible wavelengths and are prone to thermal damage, making them difficult to machine with conventional laser sources. See OLED Materials Processing with High Power UV Picosecond Lasers for additional information.

They filed a Swiss patent for the idea on Dec. 4, 1970. Though it attracted scant attention at the time, the milestone now stands as the birthdate of the liquid crystal display (LCD) – the technological platform which has transformed consumer electronics and presented a brilliant new way to view the world.

Early LCD developers took a few years to figure out that specialty glass, not plastic, was the best stable substrate for the delicate LCD circuitry and the color backplane component. Once they did, they turned increasingly to Corning to supply them with extraordinarily stable, flat, fusion-formed glass, able to preserve the critical properties of the liquid crystal and withstand high processing temperatures.

And LCDs rapidly transformed from “passive matrix” models, mostly used in pocket calculators and digital watches, to “active matrix” LCDs in which each sub-pixel was controlled with an isolated thin-film transistor. AMLCDs enabled wide viewing angles; brilliant, fast-moving images; and high-resolution images that had never been possible before.

Corning Incorporated was a critical player in this development, and eventually became the world’s leading supplier of LCD glass substrates. And Corning® EAGLE XG® Glass, the world’s first LCD substrate with no arsenic or other heavy metals, went on to exceed sales of 25 billion square feet, making it one of the most successful products in Corning’s history.

In general, there are two types of displays in the market today: active matrix liquid crystal display (AMLCD) and AMOLED. In its simplicity, the fundamental components required to make up the display are the same for AMLCD and AMOLED. There are four layers of a display device (FIGURE 1): a light source, switches that are the thin-film-transistor and where the gases are mainly used, a shutter to control the color selection, and the RGB (red, green, blue) color filter.

Technology trends TFT-LCD (thin-film-transistor liquid-crystal display) is the baseline technology. MO / White OLED (organic light emitting diode) is used for larger screens. LTPS / AMOLED is used for small / medium screens. The challenges for OLED are the effect of < 1 micron particles on yield, much higher cost compared to a-Si due to increased mask steps, and moisture impact to yield for the OLED step.

Although AMLCD displays are still dominant in the market today, AMOLED displays are growing quickly. Currently about 25% of smartphones are made with AMOLED displays and this is expected to grow to ~40% by 2021. OLED televisions are also growing rapidly, enjoying double digit growth rate year over year. Based on IHS data, the revenue for display panels with AMOLED technol- ogies is expected to have a CAGR of 18.9% in the next five years while the AMLCD display revenue will have a -2.8% CAGR for the same period with the total display panel revenue CAGR of 2.5%. With the rapid growth of AMOLED display panels, the panel makers have accel- erated their investment in the equipment to produce AMOLED panels.

There are three types of thin-film-transistor devices for display: amorphous silicon (a-Si), low temperature polysilicon (LTPS), and metal oxide (MO), also known as transparent amorphous oxide semiconductor (TAOS). AMLCD panels typically use a-Si for lower-resolution displays and TVs while high-resolution displays use LTPS transistors, but this use is mainly limited to small and medium displays due to its higher costs and scalability limitations. AMOLED panels use LTPS and MO transistors where MO devices are typically used for TV and large displays (FIGURE 3).

This shift in technology also requires a change in the gases used in production of AMOLED panels as compared with the AMLCD panels. As shown in FIGURE 4, display manufacturing today uses a wide variety of gases.

Nitrogen trifluoride: NF3 is the single largest electronic material from spend and volume standpoint for a-Si and LTPS display production while being surpassed by N2O for MO production. NF3 is used for cleaning the PECVD chambers. This gas requires scalability to get the cost advantage necessary for the highly competitive market.

Nitrous oxide: Used in both LTPS and MO display production, N2O has surpassed NF3 to become the largest electronic material from spend and volume standpoint for MO production. N2O is a regional and localized product due to its low cost, making long supply chains with high logistic costs unfeasible. Averaging approximately 2 kg per 5.5 m2 of mother glass area, it requires around 240 tons per month for a typical 120K per month capacity generation 8.5 MO display production. The largest N2O compressed gas trailer can only deliver six tons of N2O each time and thus it becomes both costly and risky

Individual packages: Specialty gases are supplied in individual packages. For higher volume materials like silane and nitrogen trifluoride, these can be supplied in large ISO packages holding up to 10 tons. Materials with smaller requirements are packaged in standard gas cylinders.

In-fab distribution: Gas supply does not end with the delivery or production of the material of the fab. Rather, the materials are further regulated with additional filtration, purification, and on-line analysis before delivery to individual production tools.

To facilitate these increasing demands, display manufacturers must partner with gas suppliers to identify which can meet their technology needs, globally source electronic materials to provide customers with stable and cost- effective gas solutions, develop local sources of electronic materials, improve productivity, reduce carbon footprint, and increase energy efficiency through on-site gas plants. This is particularly true for the burgeoning China display manufacturing market, which will benefit from investing in on-site bulk gas plants and collaboration with global materials suppliers with local production facilities for high-purity gas and chemical manufacturing.
