TCL Quantum Dot TV Global first-episode OLED future adds variable

In the television industry, the dividing line of next-generation display technology adds new variables.

December 15, Tcl, the main maker of the global television industry, officially launched China's first quantum dot TV H9700 in Beijing.

Tcl introduced the tv+ quantum dot TV, the use of quantum dot display technology in color gamut coverage, color control accuracy, red-green blue color purity and so on have advantages. These advantages of quantum dot display technology will impact the next generation of OLED technology status.

TCL Multimedia chief Technology officer Chen Guanglong said OLED has two technical paths, one of which takes the red-green-blue three colors from the glow, the size is not large, can only be applied to mobile phones; another way to take the white and scatter-colored green light, although it can be used in large size of the television field, but the color gamut does not.

In fact, Samsung has halted its OLED program for television. OLED TV in the current market in addition to technical bottlenecks, but also face low yield high cost problems.

Reviewing the history of the TV industry, each display technology to upgrade all means that an industry shuffle opportunities, back to vote, plasma and liquid crystal of the results, are witnessing the demise of a group of enterprises, as well as another group of enterprises to rise.

OLED technology has been considered as the development direction of next-generation display technology because of its characteristics of spontaneous light, however, the current industrialization of the mobile phone has been very good use, but the large size of the TV OLED is faced with low yield, high cost problems, and has been "only smell the staircase, Stray."

Chen Guanglong that the advent of the TCL quantum Dot TV, breaking the recent years of color TV display technology innovation of the empty window period, is expected to change the direction of the development of color TV display.

A quantum dot is a cutting-edge nanometer material with a grain diameter of 2-10 nm. The photoelectric property of a quantum dot is unique, it is stimulated by electricity or light and emits a variety of pure high quality monochrome light of different colours according to the diameter of the quantum dots. The main principle of quantum dots applied to display technology is through blue light sources, the quantum dots in the quantum dots are excited to release the pure red and pure green photons, and the remaining pure blue light is projected into the imaging system, thus allowing the quantum dots to emit a very pure high quality red/green monochromatic color. Thus beyond the traditional LED backlight phosphor luminescence characteristics, to achieve better imaging color.

At the conference, TCL Multimedia chief technology officer Chen Guanglong said, "H9700 is tcl tv+ Family Entertainment TV high-end flagship products, not only the first application of quantum dot display technology and true color display technology, but also equipped with the highest color gamut and resolution screen of China Starlight, achieved 110% NTSC color gamut coverage, reached the industry's highest level.

According to Chen Guanglong, by adjusting the grain size of quantum dots, we can easily and accurately adjust the light wave length produced by them, producing different colors of light, so that the color can be more precisely controlled, to achieve accurate color restoration display effect.

National radio and television product quality Supervision and inspection Center, deputy general manager of the Liu site published authoritative detection data show that, in the NTSC standard, the color gamut of ordinary LED TV only 72%NTSC gamut, the first generation of high color domain TV only 82%NTSC gamut, the second generation of high color domain TV about 96%NTSC color gamut, The color gamut of OLED TV is 89%NTSC gamut, while Tcl tv+ quantum dot TV H9700 gamut coverage is up to 110%NTSC gamut.

TCL Multimedia CEO Shanyi said, H9700 also equipped with TCL self-developed Smart Television operating system for different markets: tv+os, the operating system has an open architecture, can be compatible with Android and Linux platform, support the system FOTA upgrades, software security updates, and provide a unified standardized interface to support ATV, DTV, HBBTV, DRM and network streaming media functions, for the construction of "content + Platform + terminal + Application" of the good ecological chain to build a good software platform.

At the same time, H9700 also equipped with TCL first theater and micro-letter interconnection, mass video content and other functions. One of the first theaters is based on the TCL Double + strategy launched an important service function, is the world's largest television movie player products, really put the right to show the movie theater moved into TCL TV.

Technology upgrade of the card-TV industry

"Quantum Dot technology from the 1980 's began to study, early did not know how to use, to make a display now is a very important turning point." Chen Guanglong said that because of the additional cost of quantum dot technology, TCL's strategy is to apply this technology to high-end product lines, providing consumers with excellent visual effects.

At present, TCL Global starting quantum dot TV H9700 priced at 12999 yuan. However, Shanyi stressed that, although this is high-end products, but with OLED TV at a rate of tens of thousands of yuan price, quantum dot TV has a great advantage in price/performance.

Chen Guanglong revealed that the next Tcl in the quantum dot TV will continue to explore in three areas: first, it is to take the road of popularization, the cost down, not only for high-end product line, but also gradually expand to the high-end; second, to further exert the energy-saving characteristics of quantum dot technology; third, constantly in the technical search for breakthroughs, We strive to make quantum dots more extensive in color gamut to close to the natural color gamut.

From the industrial ecology, in the near future, Samsung, LG, Apple and other companies are actively promoting the quantum dot display technology research and development, and Amazon, Asus and other enterprises also use quantum dot technology to improve the quality of their products, as Tcl pioneered quantum Dot TV, the International quantum dot show Camp has begun to take shape.

"The whole market in the initial period, Chinese companies as a leader is a very difficult thing, rather than followers." "Shanyi that, like the development of LED TV, quantum dot TV needs to have a technology leader at the beginning, but in the future to promote the development of the whole industry, it must be more people to do the industry."

This is a breakthrough in the history of the global color TV. "China Electronic Video Industry association secretary General Bai Weimin that the next generation of TV competition, is actually color TV display technology dispute," TCL tv+ quantum dot TV, means that the first Chinese color TV companies to surpass foreign companies, to seize the commanding heights of the display technology, to win the global competition opportunities, will promote China's color TV industry chain of the overall move ”。
