OLED display technology In color TV display technology, OLED display technology is the core technology for the development of color TV in the future. OLED display technology adopts very thin organic material coating and glass substrate. When there is current passing through, these organic materials will emit light, and the OLED display screen has a large viewing angle, and can save power and have a very high reaction speed. The full name of OLED is "organic light-emitting diodes", which is a display screen technology. The OLED does not require an LCD panel, and the RGB color signal is directly displayed by the OLED diode, and there is almost no problem with the viewing angle of the liquid crystal. Another major feature of OLEDs is thinness and screen bending. Because of the self-emission characteristics of OLEDs, the thinnest part of OLED TVs can reach 4.3mm, with a thickness of only 4 sheets**. In the future, the OLED display can be folded, bent, or even hung like a piece of paper on a wall or in a pocket. The OLED display transparently indicates that the display product can combine decorative and real-world functions such as glass. Windows, walls, etc. can all be transformed into displays. OLED is a revolution called display technology. At present, whether it is upstream Samsung, LG or domestic Skyworth, Konka, Changhong, etc. are in a comprehensive layout of the OLED industry, LG has mastered 95% of the market share of OLED TV panels, Samsung has been fluctuating attitude of OLED TV has recently re-started Switch to OLED panel. In China, Skyworth, as the chairman unit of the China OLED Industry Alliance, has also spared no effort to make contributions and research on OLED TVs. Samsung and LG are currently investing huge amounts of capital in the OLED industry, and domestic panel makers are not far behind, including BOE, including China Star, will invest in the sixth generation line. It is believed that the entire OLED capital will be surging in the coming years. Although the popularity of OLED TVs may take some time, the popularity of OLED TVs is a general trend. Therefore, choosing OLED TVs is a future TV that will not be easily out of date. Quantum dot display technology Quantum dots, also known as "nanocrystals," are one of the ** nanocrystals, which are new materials with sizes between 2 and 10 nanometers, each of which is a single crystal. Quantum dots have unique photoelectric characteristics. They are stimulated by electricity or light and emit very pure, high-quality monochromatic light of various colors depending on the diameter of the quantum dots. Since the advent of quantum dot technology in the 1970s, scientists have received extensive attention and in-depth research. The industrial process has also been accelerating. In particular, there has been a major breakthrough in the display field. Excellent display performance has given color TV manufacturers a great deal of attention. Quantum dot display technology is seen as a breakthrough step in the breakthrough of LED technology ceilings, and is also regarded by many industry experts as a global display technology revolution. At present, quantum dots display technology has been fully upgraded in various dimensions such as color gamut coverage, color control accuracy, and red, green, and blue color purity. It has features such as higher brightness, wider color gamut, more pure colors, and longer life. Quantum dots, as the promising future display technology in the industry, has attracted widespread attention from color TV manufacturers at home and abroad. Samsung and TCL unswervingly followed the Quantum-dot television technology route and used quantum dot-TV as their main product. Hisense selected "ULED+ Quantum Dots" technology as the technological breakthrough of TV product lines. As a leader in the global color TV industry, Samsung has invested in quantum dot technology for a long time, not only investing in Nanosys, a German company with nearly 300 quantum dot technology patents, but also directly acquiring one of the three largest sub-point material manufacturers in the world last year. QDVision. Backed by deep technical accumulation, Samsung was the first to launch the world's only non-gaming quantum dot TV, and was the first company to restore 100% color rendering volume. This year, Samsung also introduced a huge QLEDTV lineup, including **4 series and 8 models, spanning 55 to 88 inches. Samsung QLED's optical quality sub-point TVs feature “bright, long, and wide†and can display peak brightness of up to 1,500-2,000 nits. This brightness is 6 times that of ordinary TVs and 3 times that of WOLEDs. At the same time, since quantum dots use inorganic materials, they can make screen image display life longer. Most importantly, the Samsung QLEDTV can restore 100% color rendering volume, accurately represent the DCI-P3 color space, and can restore all colors at any brightness level, providing ultra-high color gamut coverage. In addition to Samsung, TCL is also quite successful in the field of quantum dot TV. As early as 2014, TCL took the lead in introducing China's first Quantum Dot TV, officially starting the commercialization of quantum dot display technology in the domestic TV market; in 2016, TCL re-racially launched XESS QD TV, with The major breakthroughs in quality and quality have been hailed by the industry as the upstart TVs. In January of this year, TCL launched two new QD TV X2 and X3 series. Among them, X2 is a quantum dot flat TV, and X3 is a quantum dot curved TV. These two new products not only use quantum dot display technology, Dolby Vision HDR, MEMC, Harman Kardon audio systems and ultra-thin borderless design, but also equipped with the latest "thin optical film ultra-thin + ultra-thin body structure." The technology realizes an ultra-thin design of 7.9 mm plane and 6.9 mm surface. Thanks to the outstanding advantages in the quantum dot TV field, related data showed that in the second quarter of 2017, TCL achieved sales of 5 million LCD TVs, up 12.0% year-on-year; of which smart TV sales were 3.037 million, an increase of 40.8% year-on-year. From January to June this year, cumulative sales of TCL color TV reached 9.805 million units, and sales of smart TVs reached 6.158 million units, an increase of 36.7% year-on-year. It can be said that quantum dots are the better luminescent materials discovered by humans so far. Quantum dot electroluminescence will be an advantageous competitor for the next generation of display technology. The backlight of quantum dots will make the color purity and color saturation of display colors very high. Display technology is difficult to reach. ULED display technology The full name of ULED technology is Ultra-LED, which is Hisense's autonomous display technology that has been promoted to the industry through R&D for 7 years. Although ULED is only one letter lower than OLED, it is different from OLED. Here, U is Ultra, ULED is mainly for LCD TV and electronic medical. It adopts multi-zone independent backlight control and Hiview art engine technology. ULED has significantly improved the traditional color display, contrast, and response speed compared to traditional LED display, and its image quality is close to that of OLED. ULED TV Hisense ULED display technology has more than 170 patents, through the backlight multi-zone dynamic control technology, peak brightness control technology and backlight scanning control technology, to lower the cost of the LCD screen display quality to a higher level. Multi-zone backlight dynamic control technology Adaptive partition peak brightness boosting technology ULED's first adaptive peak brightness enhancement technology and dark field image detail enhancement technology can analyze the brightness distribution characteristics of each frame of the image, and enhance the peak brightness of the backlight of the corresponding area for the image scenes rich in light and dark levels and highlights in the screen. The brightness can be improved by more than 3 times, and the brightness and darkness of the extended picture can be made more rich in the image level and the three-dimensional effect can be enhanced. PCR precision color reproduction technology ULED uses a narrow spectrum high color gamut technology, RGB three primary colors of higher purity, its precise color reproduction technology can carry out adaptive color processing on the screen, to ensure the detailed expression of the image color and precise reduction. It is also with its outstanding performance, ULED also achieved 8K display, peak brightness display up to 1200 nits, is 2 to 3 times that of ordinary TV, to achieve a tens of millions of dynamic contrast and 106% NTSC gamut, Exceeds the UHD Premium's requirements for HDR display performance standards, and surpasses OLED in comprehensive display effect. Laser display technology Laser TV is not a new concept. In the 1990s, there was a technology prototype. In 2003, laser television prototypes were introduced. However, in the following years, the development of laser television was not satisfactory due to various reasons until 2012. The laser television has rejuvenated its youthful vitality. After several years of development, laser television, quantum dots, and OLEDs have become one-third of the world. Laser TV The laser display technology is a display technology using red, green, and blue (RGB) three-primary lasers as the light source, which can reproduce the most vivid and colorful colors in the objective world and provide more powerful performance. From the point of view of colorimetry, the color gamut coverage of the laser display can reach more than 90% of the color space recognized by the human eye, more than double the coverage of the traditional display gamut, completely breaking through the gamut space of the first three generations of display technology. The insufficiency of humanity realizes the most perfect color reproduction in history and enables people to see the most authentic and beautiful world through display terminals. The excellent application of laser display technology on television also won the praise of consumers. Laser TV makes the whole TV picture look more realistic, layered, and transparent, and the clarity of the picture will be greatly improved with the increase of color saturation. Since lasers are used as the backlight for televisions, laser televisions can be made thinner for home use. Laser TV also overcomes the discomfort caused by the long-term viewing of the fluorescent colors produced by the human eye, and it does not radiate to human eyes. And at an optimal viewing distance of 4m-4.5m, the 30° viewing angle on the screen allows the eye muscles to relax naturally, and the screen uses the reflected light of the laser emitter, which is almost the natural observation mode of the eyes, which is comfortable, natural, and does not hurt the eyes. . According to relevant international standards, laser-based television products are the only display products in the world that fully meet the theoretical vision requirements and are harmless to the naked eye. At present, in the field of laser television, domestic manufacturers have seized the opportunity. In 2014 alone, domestic manufacturers such as Hisense, Optoma, Changhong, Hualu, Konka, Maxwell, and Yone launched laser televisions. In 2017, it was known as the “explosion period†of laser televisions and the “Laser eraâ€. "It has officially come. 6.7MM Wire To Board Connectors
