Digital signage in the context of "Information sign"

Unified communications (UC) is a business and marketing concept that integrates multiple enterprise communication services. These include instant messaging, presence information, IP telephony, mobility features, audio/video/web conferencing, desktop and data sharing, call control, and speech recognition. UC also links with non-real-time services such as unified messaging (integrated voicemail, e-mail, SMS, and fax). UC is not necessarily a single product, but a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.

In its broadest sense, the UC can encompass all forms of communications that are exchanged via a network to include other forms of communications such as Internet Protocol television (IPTV) and digital signage as they become an integrated part of the network communications deployment and may be directed as one-to-one communications or broadcast communications from one to many.

An electronic visual display is a display device that can display images, video, or text that is transmitted electronically. Electronic visual displays include television sets, computer monitors, and digital signage. They are ubiquitous in mobile computing applications like tablet computers, smartphones, and information appliances. Many electronic visual displays are informally referred to as screens, and those that also contain some means of touch input are called touchscreens.

Starting in the early 2000s, flat-panel displays began to dominate the industry, as cathode-ray tubes (CRT) were phased out, especially for computer applications. Starting in the mid 2010s, curved display panels began to be used in televisions, computer monitors, and smartphones.

E Ink (electronic ink) is a brand of electronic paper (e-paper) display technology commercialized by the E Ink Corporation, which was co-founded in 1997 by MIT undergraduates JD Albert and Barrett Comiskey, MIT Media Lab professor Joseph Jacobson, Jerome Rubin and Russ Wilcox.

It is available in grayscale and color and is used in mobile devices such as e-readers, digital signage, smartwatches, mobile phones, electronic shelf labels and architecture panels.

Electronic signage (also called electronic signs or electronic displays) are illuminant advertising media in the signage industry. Major electronic signage include fluorescent signs, HID (high intensity displays), incandescent signs, LED signs, and neon signs. Besides, LED signs and HID are so-called digital signage.
