Evolution history of screen display technology
Evolution history of screen display technology
Every day, we watch streaming content on the screens of devices such as TVs, computers and mobile phones. With the continuous development and updating of hardware equipment and streaming media technology, screen display technology is also constantly evolving. Today, let us follow the footsteps of history and review the important milestones in the development of screen display technology.
The advent of CRT
Cathode rays were first observed in 1869 by German physicists Julius Plücker and Johann Wilhelm Hittorf. In 1897, German physicist Karl Ferdinand Braun (Braun was also the winner of the Nobel Prize in Physics in 1909) invented the CRT (cathode-ray tube, cathode ray tube), which was originally called the Braun tube (Braun tube) ), is one of the earliest electronic displays in the world.
A CRT is a special vacuum tube that contains one or more electron guns. The electron beams emitted by the electron guns hit the fluorescent screen to display images. Early televisions, computers, ATMs, video cameras, monitors, and radar displays all had CRTs built into them.
In 1907, Russian scientist Boris Rosing (who had worked with television inventor Vladimir Zworykin) used a CRT to transmit simple geometric images to a television screen. Rosing’s pioneering work also made him an important inventor in the field of television. After that, CRT technology continued to develop and was first commercialized in 1922. Before the advent of technologies such as LED, plasma and OLED, CRT has been used as the display of most equipment.
Cathode ray tubes were commonly used in televisions and computer monitors throughout the mid to late 20th century. During this time, manufacturers have continued to improve performance and resolution. Most computer monitors from the 1970s could only display green text on a black screen. By 1990, IBM’s Extended Graphics Array (XGA) display could display 16.8 million colors at a resolution of 800 x 600 pixels.
The Hungarian engineer Kálmán Tihanyi described this flat-panel plasma display system in his 1936 thesis. In 1964, Donald Bitzer, H. Gene Slottow, and then-graduate student Robert Willson at the University of Illinois at Urbana-Champaign developed the first monochrome plasma display for use in the PLATO computer system.
The principle of plasma light emission is to inject inert gas or mercury vapor into the vacuum glass tube, and after applying voltage, the gas will produce a plasma effect, emit ultraviolet rays, excite phosphors to produce visible light, and use the length of excitation time to produce different brightness. In a plasma display, each pixel is produced by three different colors (primary colors) of plasma light emitters. Since it is lit up at the same time by each independent illuminant, it is particularly clear and vivid.
Until the early 2000’s, plasma displays were the most popular choice for large flat-panel HDTVs. However, it should be noted that because plasma displays are prone to image retention, and at the same time, due to material and structure limitations, it cannot be reduced in size, so it is not suitable for computers, tablets and mobile phones. This is also the main reason why plasma displays lose in the market competition.
By 2013, it was overtaken by low-cost LCDs and faced competition in display quality from expensive but higher-contrast OLED flat-panel displays. Plasma displays lost almost all of their market share. Production of plasma displays for the U.S. retail market ended in 2014, and production for the Chinese market ended in 2016.
Liquid Crystal Display (LCD) Era
In 1888, Austrian botanist Friedrich Reinitzer accidentally discovered Liquid Crystals while studying Cholesteryl Benzoate in carrots.
In 1962, Richard Williams, a physical chemist at the RCA (Radio Corporation of America) laboratory, wanted to find a display material that could replace the CRT. During his research, he discovered that when he applied an electric field to a thin layer of liquid crystal, the crystal formed a pattern of stripes and entered a nematic state. Richard later handed over the research to his colleague at the RCA, George H. Heilmeier. After persistent efforts, the team led by George found a way to operate the crystal at room temperature and invented the first liquid crystal display, which was first shown to the world in 1968.
The structure of the LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass, and control the liquid crystal molecules by changing the signal and voltage on the TFT. Rotate the direction, so as to achieve the purpose of controlling whether the polarized light of each pixel is emitted or not to achieve the display purpose.
Although liquid crystal displays have been around since the 1970s (then they were commonly found in calculators, watches, clocks, and various household appliances), they didn’t gain widespread adoption until the 1990s. It is heavily used in notebook computers due to its low power consumption, small size, and light weight. As LCD technology continues to improve, the use of LCD screens in computers and televisions is becoming more and more popular. In 2007, LCD TVs surpassed CRT TV sales worldwide for the first time.
In 1962, General Electric engineer Nick Holonyack invented the world’s first visible light LED. From 1962 to 1968, the team led by Howard C. Borden and Gerald P. Pighini of Hewlett-Packard Company has been conducting LED research and development. In February 1969, they launched the HP Model 5082–7000 Calculator, which was the first LED device using integrated circuit technology and also had the world’s first smart LED display. Hewlett-Packard’s commercialization of LED set off a revolution in digital display technology, and laid the foundation for the development of LED display technology later.
LED is the abbreviation of Light Emitting Diodes, that is, “light emitting diode”. Strictly speaking, it is also a kind of LCD (liquid crystal display). Traditional CCFL (Cold Cathode Fluorescent Lamp, Cold Cathode Fluorescent Lamp, etc.) as the backlight of LCD devices can only illuminate the entire screen evenly, and cannot change the illumination intensity. Compared to CCFLs, LED-backlit LCD devices can use local dimming, resulting in better contrast and more vivid displays while consuming less power.
LEDs are used in most LCD smartphone and tablet displays due to their versatility and lighter weight.
In 1987, on the basis of previous research, two chemists Deng Qingyun and Steven Van Slyke of Eastman Kodak jointly developed the first practical OLED device.
OLED (Organic Light-emitting Diode), also known as “organic electroluminescent display”. An OLED is a device that utilizes a multilayer organic thin-film structure to produce electroluminescence, which emits bright light when an electric current is applied to it. Unlike LCDs, OLEDs don’t require a backlight, can use a lighter light-emitting substrate (instead of the glass substrate used by LCDs and LEDs), and have wider viewing angles and faster response speeds.
The emergence of OLED is a great progress for electroluminescent technology. Compared with LED, OLED is thinner, smaller and more flexible. It is commonly used in TV screens, computer monitors and devices such as smartphones and handheld game consoles.
Since the iPhone X began to use OLED displays, OLEDs have rapidly swept the global terminal market. Full screens, folding screens, and flexible screens have emerged one after another, which has greatly promoted the development of display technology.
The invention of electronic paper
In the 1970s, Nick Sheridon of Xerox Parc developed the world’s first electronic paper — Gyricon.
E-paper is a thin film coated with a layer of electronic ink — a liquid material in which hundreds of microcapsules about the diameter of a human hair are suspended, each Microcapsules are composed of positively and negatively charged particles. [3] When a positive or negative electric field is applied to a single electrode, colored particles with corresponding charge will move to the top or bottom of the capsule, causing the surface of the e-paper display to appear a certain color.
Like OLED, e-paper itself emits visible light while retaining the gloss of “paper.”
While electronic paper was developed in the 1970s, it didn’t become popular until the early 2000s. Its most widely used is e-readers, such as our common Kindle, BOOX, etc. Among other things, it is used in electronic pricing tags, digital signage, and some smartphone displays.
DLP technology
DLP (Digital Light Processing) is the abbreviation of digital light processing. Its working principle is to process the image signal digitally and then project it through light. This technology has extremely high image fidelity and can project clear, bright and vivid colors, and is mostly used in projector systems.
At the heart of DLP technology is an optical semiconductor known as a digital micromirror device (DMD, Digital micromirror device), which uses micromirrors made of aluminum to reflect light to generate images. DMDs, often referred to as DLP chips, can each contain more than 2 million micromirrors and are less than one-fifth the width of a human hair. The micromirrors are arranged in a matrix (much like a photo mosaic), with each micromirror representing a pixel.
The number of these micromirrors corresponds to the resolution of the screen. DLP 1080p technology provides over 2 million pixels for true 1920x1080p resolution. There are already 8K DLP projectors (using 3xDLP) on the market.
DLP was originally developed in 1987 by Texas Instruments physicist Larry Hornbeck. In 1997, Digital Projection launched the first DLP projector. In 1998, Texas Instruments and Digital Projection both won Emmy Awards for their DLP technology.
Compared with plasma and LCD equipment, DLP equipment is less expensive, and it has a larger screen and is thinner and lighter. Maybe you don’t realize that DLP technology often appears in your life. It is common in various projectors (for training and teaching), home theaters, video walls, concerts and conferences and other large projection systems.
The above are important milestones in the development of screen display technology. The development of display technology involves the integration of microstructured optical materials, advanced manufacturing, image processing and other technologies, which not only improve the resolution of device screens, but also vividly present human imagination. We believe that with the development of hardware equipment and the continuous advancement of technology, display technology will once again achieve innovative breakthroughs.
