In contemporary society, TV sets have always been the central equipment for home entertainment. Naturally, it is also the most watched consumer electronics product. Its technological development is very important for the entire consumer electronics field. From the original CRT TV to the current flat-panel TV, the pace of technological development has not stopped. The goal pursued is, as always, the larger the screen, the clearer the picture, the more natural the color, the lower the energy consumption, the thinner the thickness, and the operation. More convenient; ... the current mainstream type of flat-panel TV is LCD LCD TV, which has won the mainstream status of flat-panel TV because of its thinness, low energy consumption and high resolution. In just a few years, it has occupied the absolute dominant market. The status and development of technology can be described as a thousand miles. So, in the field of LCD TV, what technologies and products are currently the most competitive, representing the direction of technology development? TCL, which has successfully entered the forefront of global TV brands through international mergers and acquisitions, gives the answer: LED backlight, card-separated digital TV receiver and Internet TV functions combine to make TCL's P21 series LED digital Internet TV Become the most popular and most attractive flat-panel TV product. Featured LED TV leads the trend LED is the abbreviation of Light Emitting Diode, which has been used in backlighting of LCD TVs in recent years. LED TV refers to a liquid crystal TV that uses LED light source instead of traditional fluorescent tube as screen backlight. Strictly speaking, LED TV is a type of LCD TV. LED light source has the advantages of high color purity, long life, environmental protection (excluding mercury), etc. RGB-LED is used as the backlight source of LCD TV, which can make the display color gamut of TV more wide, reaching 105% of NTSC color gamut. This provides a guarantee for the color improvement of the LCD TV; the use of the side-light white LED backlight can greatly reduce the thickness of the LCD TV, making the TV overall appearance thinner and lighter. The energy-saving features of LEDs are not only more conducive to reducing energy consumption, but LED backlights are absolutely free of mercury contained in traditional fluorescent light sources, and are more environmentally friendly and have a longer service life. Based on the above advantages, LEDs have been used as backlights for LCD TVs a few years ago, but the real technology is mature and large-scale, starting from 2009, almost all companies producing LCD TVs are already producing LED TVs. . DisplaySearch, the world's leading market research organization, estimates that LED TVs will account for 20% of all LCD TV shipments in 2010. About 90% of LED TVs use edge-lit backlights. LED TVs will become the mainstream of LCD TVs in 2012. . With the improvement of energy-saving concept and the popularity of thin and light design, the conversion speed of LCD TVs from CCFL to LED backlights is accelerating. It can be said that LED TV is coming to the forefront and is becoming the first choice for the city to pursue a higher quality mainstream consumer group. LED TV is an unstoppable technology trend. For consumers, it is wise to choose LED TV, but it is not just the use of LED backlight to win the favor of consumers, because the TV is not just a screen, The combination of novel and practical and intimate features is the king of the LED TV boom. How to stand out in the market of product and technology homogenization has become a big plan for leading companies to seriously consider and plan ahead. As the most international TCL in China's TV brand, it successfully integrates Internet functions, all-in-one functions and LED backlights to create the most unique and unique LED digital Internet TV, which has successfully led the trend of LED TV. A new generation of LED backlight technology As a multinational large-scale TV manufacturer, TCL has the ability to gain insight into technology and take the lead in the industry. For example, the P21 series LED digital Internet TV launched in the first half of this year is not just a simple application. LED backlight technology, there are a number of special technologies to improve the image quality of LED screens, which laid a solid foundation for it to stand out in many LED TVs. The TCL P21 uses a new generation of LED backlight technology, which is a white-light side-light type. It achieves higher contrast and richer color performance, and also ensures the ultra-thin characteristics of the TV screen and the low power consumption of the whole machine. In addition, it uses a unique dynamic backlight to adjust the backlight point by point. This technology can improve the contrast better, and provide the intensity of the backlight on demand, which is more energy efficient. The natural light technology that TCL has been using has also been inherited on LED TV. This unique TCL technology converts the direct light of traditional liquid crystal into natural light that protects the eyes, effectively reducing the visual fatigue when users watch TV programs. It contains five major adjustment technologies: natural color, natural light and natural level. It also greatly reduces the TV energy consumption while improving the picture quality. In addition, the P21 series uses a cold screen design, which effectively reduces the temperature of the TV screen when working, making the screen and the whole machine last longer. The P21 series LED screen also combines 120Hz and MEMC frame insertion technology to form 240Hz multiplier processing technology. This technology takes into account the clear outline of the image and the natural transition of detail, which can effectively prevent the image from tailing and reduce the image blurring and blurring. Smoother and more natural, it is especially suitable for sports events and action movies. At present, most of the high-end LED TVs of multinational corporations adopt this technology. As a successful TCL in the international brand, the whole line of LED TV products adopts 240Hz frequency multiplication processing technology, which is also a concrete embodiment of the world's leading TV brands. In addition to the above-mentioned unique technologies belonging to LED screens, the P21 series also features a unique patented technology - full-field display. As the name suggests, full-field technology is able to display the complete picture broadcast by the TV station. Most consumers don't know that the TV screen we usually see on the screen is not the complete picture broadcast by the TV station. The edge of the screen is cut off: only 95 are displayed in the horizontal and vertical directions of the program screen. About %, the displayed area is about 90% (95% × 95% = 90.25%). There are two reasons for this: First, the traditional CRT TV scanning line size sometimes shrinks, so it is necessary to display some pictures and leave a margin; second, some TV programs are not standardized, if the complete display will be around Some black bars, white bars and other non-program content appear. After entering the era of flat-panel TVs, because LCD TVs and plasma TVs do not have the problem of changing the line width, and the TV program production has been relatively standardized, most programs have 100% complete display of their pictures, so the complete display is already Feasible and necessary. In this context, TCL took the lead in launching an action that allowed viewers to see a more complete picture. This is its full-field technology. TVs with TCL full-view technology can bring the following benefits to consumers: 1. The scope of viewing and content increased. The analogy of playing an image: like the frame of a camera, the field of view of a conventional TV set is only cropped 90% of the program picture (that is, the input signal) and then enlarged and displayed on the screen. The full view is the complete program picture. That is, the complete input signal is displayed on the screen. Watching the same TV program, TCL TV will watch more than 10% of the content in the "full-view mode" than other TVs, and there will be no such phenomenon as subtitles under the screen. 2. Improved clarity. With the same size and resolution of the TV screen, the display content (or effective information) is 10% more, and the clarity is improved accordingly. 3. The user has the freedom to choose. Since individual TV programs are still not standardized, some non-program content such as black bars/white bars will appear in the full-view mode. Some users may be disgusted with this. TCL's approach is to let users in "conventional vision" and "full view". Free choice between, very human. Machine card separation leads the digital one machine According to the different signal transmission media, the current digital TV is mainly divided into three types: cable, terrestrial and satellite digital signals. In recent years, China has successively introduced corresponding digital TV national standards, and various localities have also begun to transform cable digital TV systems. High-definition digital TV programs and digital TV terrestrial signals have also been piloted in some regions. The State Administration of Radio, Film and Television has already clarified the policy of stopping the broadcasting of analog TV signals in 2015. Among the three transmission modes of digital TV signals, cable digital TV signals are highly praised for their stable signal source, environmental protection, convenient use, and rich programs. It is also the most mainstream way for urban people to watch digital TV programs. In view of this, TCL adopts the wired digital signal receiving mode of "machine card separation" mode for the P21 series, which can directly watch high-definition and standard-definition digital TV signals without the need of a digital TV set-top box. Of course, watching analog signals is not a problem. In this way, the user can save money on the external digital HD set-top box, and can reduce one device to make the home environment more refreshing and neat. Separating the cable digital signal receiving method from the machine card is the best way and is in line with national standards. This method is simple and convenient. As long as the digital signal is decrypted and the small card of the charging part is inserted into the big card of the digital signal decoding device, it is installed on the existing slot of the television, just like the relationship between the mobile phone and the SIM card. By connecting the cable TV signal, you can watch the digital TV program normally. The card-separated digital all-in-one is not restricted by cable TV operators in different regions, and can be used in any place where cable digital TV is available. At the same time, in response to the current situation that the signal strength of cable TV lines varies under different conditions in different cities in China, the TCL P21 cable digital all-in-one has built-in enhanced signal receiving equipment, which greatly enhances the sensitivity of the TV to the signal, thus obtaining a more stable and clear image. effect. Compared with the terrestrial digital TV receiver tuner used by other brands of digital TV receivers, TCL's wired digital all-in-one mode is more in line with the actual needs of domestic urban users, and is a more pragmatic technical choice, but also fully in line with national standards. of. The separation method of the machine card gives the user more freedom to choose the space. It is easy to replace, and has many advantages compared with the built-in set-top box mode: the built-in set-top box has the same effect as the external set-top box, and the signal is easy to lose, which affects the quality of the sound and picture. At the same time, the built-in set-top box is equivalent to adding a set of circuit boards in the TV set, and the failure rate will be increased accordingly. When the set-top box is working, it may generate electromagnetic waves that are not in harmony with the TV set, which interferes with the picture quality. In the case of a user relocating to a foreign country, a professional engineer needs to switch on the built-in set-top box to use it. Even in different parts of the city, there may be cases where it cannot be used (such as Guangzhou and Nanjing). The built-in set-top box will increase the thickness of the body, the internal space is smaller, the heat dissipation is worse, the screen temperature is increased, and the life is affected. The weakness of these built-in set-top boxes can be solved well in the machine card separation mode. The trend of Internet function As the first company to propose the concept of Internet TV, TCL has succeeded in taking the lead in the field of Internet TV. It has invested heavily and gained a lot. It is a well-deserved Internet TV leader. After the State Council identified the first 12 pilot cities for triple play, the pace of triple play in China has obviously accelerated, and the business model has gradually become clear. The future convergence of the three networks will become an irreversible trend. In this context, the development prospects of Internet TV are more clear and more emboldened. TCL is undoubtedly a great beneficiary of this policy, and its exploration and innovation in Internet TV technology has increased its weight in its own market leading position, built-in second-generation Internet TV operating system, let TGL P21 series LED digital Internet TV is even more powerful, becoming the most powerful LED TV in the Internet. In order to better utilize the powerful functions of the second-generation Internet TV operating system and make the operation simpler and more fun, TCL developed a novel intelligent remote control for the P21 series. The innovatively designed smart remote control removes all the complicated buttons. All operation needs can be achieved by simply tapping the turntable. With the built-in second-generation Internet TV operating system of P21, the design is convenient, and the cursor can be displayed to display the next-level directory, so that users can get the best operation experience. In addition to continuous improvement and excellence in product functions, TCL has also actively and extensively cooperated with content providers. Through the strategic cooperation between China Digital Interactive Channel and China Network TV CNTV, which has obtained national licenses for the integration of the three networks, it has become The industry's first TV manufacturer with two national licenses, TGL Internet TV users can enjoy the massive video resources of China Digital Interactive Channel and CNTV, which can be described as the network video resources. With weekly updates, users are free to choose the latest, classic movie and entertainment content they like to watch. And there are a lot of practical and entertainment functions such as new distance education, online karaoke, somatosensory fitness online games. In addition, TCL's Internet TV also has a unique online intelligent upgrade function. Whether it is the function software upgrade of the TV or the upgrade of the Internet information, it can be easily and automatically completed under the network state, so that the TV will always be advanced, technology and content. Forever, this is really a very commendable feature. It can be said that the innovation and progress in the software and hardware functions of the TV itself and the deep strategic cooperation with the content providers have made TCL in the field of Internet TV, which has further consolidated its leading position in the field of Internet TV. In this era of low-carbon and environmental protection, TGL has not forgotten its own corporate social responsibility. In addition to vigorously developing more energy-saving and environmentally-friendly LED-backlit LCD TVs, it also strives for excellence in the details of related functions, such as the application of synchronous variable frequency power supply technology. LED TV continues to be subdivided into “super energy-saving series†in the field of LED TV. TCL synchronous variable frequency power supply technology is the first in the industry. It adopts dual power management mode, which not only greatly improves the efficiency of power supply, but also achieves ultra-low standby power consumption. It further enhances the brightness uniformity of the entire screen of the TV, thereby improving the image quality more effectively. The perfect combination of LED backlight, machine card separated digital TV receiver and Internet TV function is TCL's definition of the mainstream TV in the future under the trend of triple play, and it is also the highlight of its P21 series LED digital internet TV. The characteristics are bound to become the most eye-catching scenery in the TV field.
