Visual information is presented using a device called a display. The main objective of any display technology is that information sharing is to be simplified. Nowadays, for different applications, different types of displays are used. 3D displays, video displays, and non-video displays are the displays categories. A variety of multimedia formats is presented to the audience with the help of digital displays. The ability to show a wide range of multimedia formats like images and videos is considered an advantage of digital displays. Which made it to be the superior communication mode. The key factor for the growth in display adoption is that reduction in its price and growth in its output quality.
Evolution of device display
The first display technology is the cathode ray tube was in the year 1897. Even though it is bulky, inefficient, full of hazardous waste materials, and heavy it has a long incredible run. In the 20th century, it was pretty much owned.
According to business intelligence tools, the discovery of electroluminescence took place in 1907. Electroluminescence, a natural phenomenon was discovered by British radio researcher, Henry Joseph Rounds. It is a light that will not produce heat. This leads to the foundation of LEDs, and it is an efficient way to produce light compared to incandescent.
Market analysis states that between 1961-1962, LED was discovered. LED (Light Emitting Diode) which is visible to the human eye was discovered by Nick Holonyack and he is called “The father of LED”. Initially, it had less efficiency and color options, LED developments are considered the light source of the future. Post the invention of LED, LCD and PDP entered the market. It took a while until these technologies evolved in the mainstream. Mass production of LCDs is dominated. Due to their higher weight and lack of size scale, plasma displays were limited.
According to market database, the invention of OLED took place shortly after in 1987. It is an advancement in electroluminescence that is OLED (Organic light-emitting diode) was invented by researchers at Eastman Kodak. OLEDs are flexible, thin, and small compared to LEDs. Billions of dollars are invested in R&D, to invent OLED which is less in cost of manufacturing. They have a limited life span compared to LED and LCD technology.
In 2007, Plasma television beat out LCD television as the consumer choice is to low cost and large size. LCD will offer lower production costs, greater durability, and longer lifetimes.
By 2008, Active-matrix organic light-emitting diode (AMOLED) was introduced in the market. It was noted to bring infinite contrast ratio and with increased resolution to the table as opposed to competing technologies. In OLED TVs and phones, this is the technology that is being used. In this technology, the display is no more rigid, and the backlight is gone. The big disadvantage of this technology is that organic materials tend to die out. Consecutively, the increased market proliferation of e-reader took place in 2012: Around 40 years ago epaper was invented, but an increase in the popularity of ereaders and other devices happened recently. The e-Readers overcome the disadvantage caused by LCD and OLED.
Next was noted to be a “secret production” by Apple for the development of Micro-LEDs, a technology that was showcased to the crowd at the consumer electronics show in 2018. High color reflective and high-resolution LCD by BOE at DisplayWeek show is showcased in 2018.
Video Displays and their types
The Video display covers a full area, basically, it is a rectangle and it is two-Dimensional. Market analysis suggests that the various types of displays are Electroluminescent Display, Electronic paper, LED and LCD.
As per market database, an Electroluminescent Display is a flat panel display that works on the principle of electroluminescence. Electroluminescence is a type where in response to the electric current materials can emit light. Gallium Arsenide (GaAs) is an electroluminescent material for the use of the electroluminescent display. It consists of electrode layers at the top and the bottom, it is the basic structure of the electroluminescent display.
Business intelligence tools state that Electronic paper is a display technology resembling paper is called Electronic paper or e-paper. There is an increased demand for this display because of its thickness, flexibility, contrast, and readability.
According to market analysis, LED, popularly known as Light emitting diodes are used in the display. It emits light due to an electric luminescence. “Cold light” is another name for LED. The diode emits light when flowing through two coated silicon semiconductors. It is one of the power-saving and energy-efficient ways to produce light. While, business intelligence tools suggest that Liquid Crystal Display (LCD), depends upon the liquid crystals’ light modulating properties. It is made to be good use in electronic components since they are low power consumption equipment.
