LED New generation display technical specifications released in Beijing

Recently, the 'LED new generation display Technical Specification' was released in Beijing. For the first time, the definition of led TV product characteristics has been clarified from the perspective of industry, which will play a positive role in promoting the future LED product specification. Lu Jianbo, deputy secretary general of China Electronics Chamber of Commerce, pointed out that 2014 is the first year of led TV development. As more manufacturers launch new LED TVs, this product technology will become the mainstream TV display technology in the future. The first LED display technical specification was released. As the LED market is in the ascendant, the 'LED new generation display Technical Specification' (Hereinafter referred to as the 'specification')Officially announced. This is also an industry self-discipline norm since LED entered the market. Lu Jianbo, deputy secretary-general of the China Electronics Chamber of Commerce, said in an interview that since the LED market has just emerged and the volume has not yet been released on a large scale, in order to avoid the problems of true and false 4K TVs, everyone unanimously decided that before the introduction of national standards, the self-discipline norms of the nature of industry alliances should be introduced first to ensure the future LED market order and effectively restrict the future market. It is understood that the 'specification' comprehensively defines led TV from six aspects: display visual angle, color saturation, contrast, response speed, body thickness and weight, and curved surface design. Among them, the stipulated color gamut coverage rate can reach more than 115; Contrast can achieve infinite contrast; The response time can be less than 1 microsecond; The thickness can reach 5mm or less; Present a good surface design. Lu Jianbo said that at present, there are many LED TVs sold by LG, Changhong, Skyworth, Konka and other enterprises in the market, and the mainstream size is concentrated in 55 inch, there will be more sizes and specifications on the market in the future. Whether to adopt surface design has become the focus of controversy. From the 'specification', it can be seen that the surface design with good presentation is listed as one of the six specifications. however, among the member units that initiated the 'code', there are also products that use non-curved surface design. Whether LED TVs should be designed as curved surfaces has become the focus of industry controversy. Shenzhen Skyworth- Liu Yuzhi, president of RGB Electronics Co. , Ltd. , said in an interview that Skyworth's 55 inch-inch led TV will not use curved surface design, and said that the 55 inch-inch curved surface LED market is not available. He stressed: 55 inch TV is not conducive to the viewing of family members, there will be blind spots. However, curved LED with larger size will have more visual impact and curved design will be more effective. LGDisplay, one of the two LED panel providers, has also introduced products with different designs in its own LG Electronics led TV products, the same 55 inch led TV LG adopts two designs of plane and curved surface. The industry explained that: in fact, the LED is made into a curved surface and a flat surface, which will not increase any technical cost. Because the LED is thin, it can be controlled below 5mm. therefore, large-sized flat plates naturally have bending characteristics, so the nature of LED determines that it can be designed as curved TV, but how to design end products in the market depends on how the enterprise chooses. The relevant drafters of the specification said in an interview that in the process of formulating the specification, they mainly wanted to tell the enterprises and consumers in the industry what the LED should look like, therefore, writing the curved surface design into the 'specification' does not mean that the LED must be curved, because LCD TVs can also be made into curved surfaces, but the cost will be greatly improved, so LED is suitable for making curved surfaces. The content stipulated in the 'specification' is to present a good curved surface design, which means that LED can present a curved surface design and is a good plan, and does not stipulate that as long as led TV must be made into a curved surface design. The display effect is better than that of LCD TV. As a new generation of display technology, LED has many advantages in image quality performance compared with LCD TV on the market at present. Sun Qifeng, the digital TV standard compliance testing center of the Ministry of Industry and Information Technology, believes that compared with the traditional LCD TV with passive light sources, LED has the characteristics of self-luminous technology. therefore, it has the characteristics that traditional LCD TVs cannot match in terms of image quality and appearance design. It is understood that the unique self-luminous technology structure of led TV can achieve infinite contrast, far exceeding the limited contrast of LCD TV 5,000: 1; Compared with LCD TV, led TV has a wide viewing angle. From all angles, the picture is always clear and undistorted, and there is no distortion of the picture. The response time of led TV is only 0. 001 ms, which is 5000 times faster than the response time of 5ms of LCD TV, and its response speed has exceeded the range that can be recognized by human eyes, that is, the displayed dynamic picture has no tailing and the image has no overlap; Led TV can present a wide color gamut of up to 115, and the color display is more colorful. Sun Qifeng said that because it is a new generation of display technology, the market is still in the training period, and some actual conditions in the market need to be further improved and comprehensively investigated, so the national standards have not been introduced soon. However, Lu Jianbo stressed that since the market is just in the start-up period and the national standards still need to go through complicated processes such as initiation, project approval, draft and submission, therefore, it is difficult for national standards to be introduced in advance in advance of the market. It also depends on the product characteristics in the actual market and the actual needs of consumers, and then it is jointly initiated and discussed by enterprises, which takes quite some time.
