The world’s largest 3D LCD TV bids 170,000 yuan in China

LG Electronics has released the world's largest 3D LED backlight LCD TV, the 72-inch LG LEX9, in Beijing and announced that the TV will be mass-produced. As "the history of the largest 3D LED backlight LCD TV", the price listed in China is as high as 170,000 yuan, and the high price may be thousands of miles away from the general public.

Jin Longcheng, president of North China Region of LG Electronics (China) Co., Ltd., told the “China Electronics News” reporter: “After the development of the 72-inch ultra-large 3D LED backlight LCD TVs, the image of the product was displayed at the time of May Day in the country. More than 200 stores and more than 50 stores in North China took part in product demonstrations.In fact, at the time of initial pricing, they also thought that the price of more than 100,000 yuan was for customers, so that they could buy this product. "At the time of the show, it was not for sales. It was to demonstrate our technical strength; but many consumers came to the store and they were determined to buy this product. From September, the 72-inch LEX9 LCD TV was officially put into production." The customers faced are VIP customers from high-end groups. VIP activities are carried out against them to take advantage of 11 to launch formal sales activities."

According to LG, for a 3D LED backlight LCD TV, the real core technology includes LED backlight source, refresh rate. In the LED backlight, LG has developed a new generation of LED backlight technology - FULL LED backlight. Because the side-entry type is to place the LED unit on the upper and lower sides of the screen, the picture quality is not enough; while the direct type is to place the LED unit evenly behind the panel, backlighting, the thickness and heat dissipation are worse, so the FULL LED backlight picture quality is more exquisite The thickness is smaller. In fact, FULL LED replaces a single LED light emitter with a direct-lit one, such as a 55-inch LCD TV with 1,200 backlights, which allows precise control of dozens of regions. The full-screen LED unit greatly enhances the contrast and brightness of the screen, making the color performance more accurate, and the appearance can be slim and stylish. A large number of uniformly distributed LED lights allow the brightness of the TV screen to be higher, the black color to be darker, the brighter color to be brighter, and the leakage of light and the non-uniformity of the picture are eliminated. At the same time, FULL LED backlights can save nearly half the power of conventional LED backlight LCD TVs. In addition, for 3D LED TVs, a high refresh rate means that the picture is more stable and less likely to flicker. Currently, the refresh rate of mainstream 3D LED TVs is 200 Hz. That is, the average image received by the left and right eyes is 100 frames per second. This is the basic condition for achieving clear 3D TV images. However, if you want to enjoy high-speed racing and fast 3D game scenes without worrying about smearing and afterimages, and more eye protection, you must double the refresh rate of 3D TVs, so the highest speed 400Hz refresh rate is undoubtedly the most Best choice.

Zhang Subing, a senior engineer at the China Electronics Standardization Institute, pointed out that "3D TV is a visual revolution. Large size and health represent the trend of 3D TVs. Good 3D TVs should have several elements: first, the screen should be large and the size should be larger. The more shocking the effect is; Second, there must be super dynamic performance and color reproduction capabilities, which requires a better backlight and a higher refresh rate; In addition, the left and right eyes feel the brightness, color, clarity and other indicators It should have a good degree of consistency."
