Quantum Dot TV: The Smooth Transition of LCD TVs
Technology Core: Quantum Dots
Representative enterprises: TCL, Samsung
Quantum dots first entered the color TV industry in 2014, followed by TCL, Changhong, Samsung and other domestic and foreign companies have launched quantum dot television, because of outstanding picture quality, has gradually become the focus of industry attention. The so-called "QD TV" currently on the market, like LED TVs, belongs to the branch of LCD TVs.
From a professional point of view, quantum dots are solution semiconductor nanocrystals. Each small particle is a single crystal. It is only necessary to change the size of the quantum dot to obtain the desired color. The color purity is very high, and the crystal stability is also high. Very high, this is something that other materials can hardly reach.
Popular point of view, compared to traditional white LED TVs, quantum dot products have the ability to override OLED's full color gamut display, narrowband continuous spectrum, higher color purity, 95% close to natural light, powerful color reproduction, high color accuracy ... so it can be said that quantum dots are currently the best LCD TV backlighting technology, which can significantly enhance the color performance of the picture rather than simply increasing the saturation.
Defects: To truly compete with OLED TVs, QD TVs must be upgraded from the first stage of "photoluminescence" to the second stage of "electroluminescence." If the quantum dots really do electroluminescence, it will have the same "self-illumination" characteristics as the OLED, and the black field will naturally be comparable to the OLED. Then, when will the true "electroluminescent" quantum dot TV come out? The answer given by TCL is: from now on, after 3 years from R&D to the production stage, 5 years later the printing technology will be realized.
OLED TV: Natural Beauty
Technology Core: Self-luminous
Representative company: Skyworth, LG
2015 is arguably the fastest growing year for OLED. This technology has been out for a long time and has been in a tepid state. Although many people know that it is natural beauty, it has a variety of unique advantages. However, there is no one hundred percent perfect product. Some small flaws in it are enough to make the consumer market compress its tolerance. Of course, there are those who focus on LCD technology for many years, too late to change or do not want to be overturned manufacturers, there is a little excluding OLED technology.
OLED is also called Organic Light Emitting Diode. It is a kind of screen material that can be self-illuminated. LCD's flawed “leakage†naturally does not appear on OLED display devices, and the black field performance is very powerful. This kind of light emitting method We also collectively referred to as "electroluminescence", it can bring the ultimate black, high contrast, fast dynamic response, ultra-wide viewing angle, the most natural and vivid colors.
Why did the OLED's secretive efforts continue to respond even before 2015? This is because price, supply chain, and industrial security are still the three major obstacles that currently affect the popularity of OLED TVs. In particular, early OLED yields were particularly low, and there was no technological improvement. It would be impossible for a few people to absorb the price of its geography. The 55-inch Full HD OLED TV marketed by LG in 2013 is priced at RMB 60,000, but now the price of Full HD OLED TVs listed by China's color TV companies is around RMB 10,000.
Defects: OLED has a lot of advantages, there are still a lot of shortcomings can not be ignored, such as the real OLED display architecture without white light, its display life is too short, and the screen panel cutting yield is low, resulting in Panels are expensive and are problems that manufacturers cannot ignore.
Laser TV: The Opportunity of Large Screen TV
Technology Core: Short-throw projection
Representative enterprises: Hisense, Sony
Laser TV has always been cultivated by Hisense personally. There is a sense of solitary heroes. Fortunately, on August 10th, Sony first introduced a 100-inch ultra-large 4K HDR LCD TV in China, and announced that it will enter the high-end market in China. A month ago, the domestic color TV giant Hisense has taken the lead in the world's first 100-inch 4K ultra-short-focus laser television products, and the price is only more than 10,000 US dollars, is one-tenth of the current 100-inch 4K resolution LCD TV about. The successive moves of the world's two leading brands have shown that Super Screen TV products have become a consumer trend.
Many people may mistake laser television for ordinary projection technology. In reality, laser television is more like a cross-version upgrade of projection technology. The most important feature is that the contrast and saturation of the laser television screen are greatly increased, which has a good suppression effect on the ambient light, and the ultra-short-focus performance is also more space-saving. The layout of laser television is an important strategy for the future market competition and industrial layout of Hisense, and enterprises that emphasize independent innovation will be able to achieve significant development in the future.
Laser TV just made up for the shortcomings of LCD TVs in large size, giving consumers new choices. Hisense began to lay out its laser display technology in 2007, and it has now achieved a completely independent operation from laser TV R&D, design, and complete machine manufacturing, and has 217 patented technologies. At the same time, Sony also stated that its current technical level can completely make a clearer picture appear perfectly on a 100-inch screen.
Defects: Laser TV has its own advantages. It is the largest TV on the screen at present, watching TV has the feeling of a movie. And the price is at least 2/3 more than the same size LCD TV. However, laser television is still essentially a projection, which determines that it is vulnerable to ambient light. There is a certain gap between current picture performance and OLED TVs and quantum dot backlight LCD TVs.
Nobody dares to bet on a single technology
The current display technology trend is very unpredictable. When OLEDs are put on the market, many people are optimistic about OLEDs, saying that OLEDs will be the next generation of display technology. However, after so long, OLEDs have indeed not really separated from quantum dots. In terms of performance, quantum dot display technology and OLED display technology are generally very room for development. Laser TV is still in its infancy, but there are many opportunities in the large-screen TV market.
In fact, no one company, including Hisense, Samsung, TCL, Skyworth, and Changhong, has now completely finalized the development direction of the next generation of display technology. It is only “a comprehensive layout and focuses on itâ€. Then wait for the opportunity, quickly cut in, and then finalize the final leader. For example, Samsung and TCL are the leading players in Quantum TV, but Hisense and Changhong have also been deployed. For another example, LG and Skyworth are steadfast advocates of OLED, but Samsung, Hisense, and TCL have not given up. Similarly, Hisense, Sony, Changhong and other companies are still actively deploying laser displays, including Samsung and TCL are actually following up with corresponding technologies.
Motion Control Sensor is an original part that converts the change of non-electricity (such as speed, pressure) into electric quantity. According to the converted non-electricity, it can be divided into pressure sensor, speed sensor, temperature sensor, etc. It is a measurement, control instrument and Parts and accessories of equipment.
