The traditional display technology features a cathode ray tube (CRT) based on the principle of a steered electron beam excitation of a fluorescent screen. The structure of a CRT comprises a vacuum tube with one or more built-in electron guns, which produce the electrons to be accelerated and steered. The steered electron beam excites one or more of the pixels on the screen designed to emit the primary colors - red, green, and blue. By appropriate scanning, an image is produced on the phosphor pixelated screen. Since the invention of the first color CRT television in 1950, cathode ray tubes dominated the display market for many decades because of its outstanding characteristics such as excellent visual depth of field and high response rate.

The global market is witnessing a high degree of innovations in several consumer electronic segments, the emergence of smart wearables, and their transition into hearables. The technologically advanced wearable devices are focused on offering several real-time solutions, rather than just providing heartbeat and steps tracker, basic biometrics, streaming music, answering calls, and operating connected devices. The solutions offered in innovating hearables include sound transparency, ambient noise control, speech elevation, and augmented hearing functionality.

Music has remained an integral part of human evolution, with music being used for purposes such as communicating, mourning, celebrating, and telling stories. It has had its own recreational, aesthetic, cultural, historical, and artistic value. However, what remains a key area of focus is the appropriate delivery of music in the exact form of its origin. Often, when we listen to a recorded version of music, be it in any form, there tends to be a slight difference in the tone, notes, and other acoustic frequencies with the actual version. Although this difference is seldom detected and brought up, the key remains in minimizing and removing this defect completely. The detection and removal of sound difference have led to the development of in-ear monitoring systems.

Holographic imaging, one of the most talked-about technologies across the globe, is not new but has been in practice for years. The technology was a chance discovery by a Hungarian scientist, Dennis Gabor, in 1948, while he was working on a project to improve the quality of electron microscope imagery. The major development in holography technology was seen in the 1960s when the laser as a light source was invented. Since then, the technology has penetrated various domains with major usage in the healthcare and display industries.
