In the past 10 years, LCD technology has become the sole dominator in the field of display. In the next 10 years, OLED (Organic Light Emitting Diode), which is known as the next-generation display technology, should ban LCD technology and achieve a hegemony. Technology bans the same huge CRT technology. However, LCD technology is not willing to sit still, the ultimate evolution will be achieved in 2015, if you want to know what is the "perfect form" of LCD, please don't miss this article.
Liquid crystal is a kind of material that cannot emit light by itself. It needs to be operated by an additional light source. This physical property cannot be changed. Therefore, the "ultimate evolution" of liquid crystal technology naturally needs to start from the backlight system. The backlight system of liquid crystal technology mainly undergoes two stages of CCFL (Cold Cathode Fluorescent Lamp) and WLED (White Light Emitting Diode).
Quantum Dot QLEDs evolve LCD technology to the "perfect ultimate form"
In 2015, LCD technology will usher in the "ultimate evolution" of the backlight system - quantum dot QLED technology, both in terms of performance and power consumption have revolutionized breakthroughs, however, considering the inherent physical properties of liquid crystal technology is completely at a disadvantage, quantum dots The QLED backlight is very likely to be the last revolution in the history of liquid crystal development after CCFL backlighting and WLED backlighting. This is why we define it as “the ultimate evolutionâ€.
2015: Samsung will lead quantum dot QLED technology to become bigger and bigger
Insider reliable news, the leading player in the TV field, Samsung will launch LCD TV based on quantum dot QLED backlight technology in 2015 (meaning Samsung will be stranded indefinitely OLED TV program), domestically produced TCL will be listed as the end of the quantum dot at the end of the year QLED TV products, LG Display as the top LCD panel manufacturer, has announced that quantum dot QLED panels will be mass-produced, in addition to BOE, Huaxing Optoelectronics and other panel manufacturers will be able to support quantum dot QLED backlight technology. So, why can quantum dot QLED backlight technology make so many giants dump it?
Quantum Dot QLED: Technical Principles / Development History
â— Quantum dot QLED backlight technology
QLED is a shorthand for "Quantum Dot light Emitting Diode". The Chinese translation is a quantum dot light-emitting diode, also known as quantum screen display technology. This is a new technology between liquid crystal and OLED. The principle is through blue lED light source. The quantum dots are illuminated to excite red and green light. The core technology of QLED is “Quantum Dotâ€, and the quantum dots are composed of zinc, cadmium, selenium and sulfur atoms.
QLED structure principle
As early as 1983, scientists at Bell Labs in the United States conducted in-depth research. A few years later, Yale University physicist Mark Reid officially named it "quantum dot." After years of painstaking research and development, panel manufacturers such as Samsung Display, LG Display, Huaxing Optoelectronics, and BOE have announced that QLED quantum screens are ready for mass production and sound the official commercial horn.
