Founded in 2009, Sansi North America (SNA Displays) has become a leading LED display manufacturer in the United States with offices across the country and LED displays in major cities from coast to coast. We are the only LED signage manufacturer headquartered in Times Square and boast a major percentage of the digital LED displays in the world’s most coveted advertising space right outside our doors. In recent years, we’ve provided more LED display technology to Times Square than any of our competitors. Likewise, SNA Displays leads the industry in providing LED screens to the Los Angeles area and other major markets in North America.
Whether from the BRILLIANT™, BOLD™, or EMPIRE™ product series, our LED screens come in a vast array of sizes and pixel pitches for numerous indoor and outdoor applications. Whether you need an LED display screen for a conference room or one big enough to cover a skyscraper, SNA Displays has the custom-engineering knowledge and experience to make your vision come to life. We also have all-in-one, out-of-the-box LED screens perfect for on-the-go messaging.
SNA Displays emphasizes maximum communication throughout all phases of each of our projects. When you choose LED display products from SNA Displays, you not only get top-tier technology but a dedicated point of contact who will work with you from start to finish. Every project manager at SNA Displays is a structural, electrical, or mechanical engineer, meaning that our SNAPros™ have the engineering chops to help you at every step along the way, from design to installation to commissioning.

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 LC displays (LCDs) 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.[31] Samsung sells a luxury and commercial product called "The Wall", which consists of several microLED display modules tiled together, like in most video walls.

This list lists current LCD fabrication facilities, former facilities are below this first table. 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. Panel Inputs per month is how many substrates can a plant process per month.
