Company News >> Hisense Yang Jia: ULED + quantum point is the most real "window" 13th,Mar,2017
                                     March 9, held in Shanghai, China Home Appliances and Consumer Electronics Fair (AWE), Hisense ULED will be carried out in the end, released the 2017 TV quality benchmark for - 75 inch DIA series ULED super quality TV. Why does Hisense make a special liking for ULED? Hisense ULED backlight in the end what secrets? I have the honor to interview the AWE Hisense ULED technical director Mr. Yang Jia, together to explore the story behind the ULED.
                            "TV is the pursuit of real, television is like a window, through this window users can see a more real world.
                             Yang Jia said that for watching TV, all the pictures are presented by two elements: one is light, one is color. Which ULED can get more accurate backlight, and the quantum dot is a very good color gamut to enhance the technology, the color gamut is flat, the brightness is deep, the combination of the two can be better to enhance the three-dimensional color space, get more real Of the screen effect. Hisense Tianji series ULED super quality TV officially set the two points of the long, as the 2017 LCD TV quality benchmarking products, but also Hisense LCD technology to promote the upgrading of another milestone products.
                             In addition, ULED and quantum dots are different in each stage of the development of LCD TV along the ultimate quantum dots. At this stage, the quantum nodes are supplemented by quantum dots at the present stage. , Quantum dot technology may be the main, ULED will get some inheritance, but the proportion will decline.
                             In addition, this "window" is not only more and more real, but also growing, and large-screen has become an absolute trend.
                             Yang Jia that there are two main reasons, the first is the signal content of the high-definition, and now now both high-definition cable signal or network video clarity has greatly improved to meet the needs of users to watch high-definition; The TV itself, the signal processing capacity is getting stronger and stronger, showing the device resolution / contrast is getting higher and higher, in the past to see the LCD TV, if too close, the picture will be grainy and other issues, and now have been A lot of improvement, and the big screen can also bring a better sense of immersion.
                             In the end is not suitable for the choice of 75-inch TV, Yang Jia also gives a formula: TV height of 3 times, if it is 4K TV, divided by 2.75 inch LCD TV height of about 1 meter, if Is the FHD TV, the viewing distance is 3 meters, while the 4K 75 inch LCD TV viewing distance of about 1.5 meters.
                            Of course, ULED is also in the continuous upgrading of which allows users to get a more realistic picture, Yang Jia said ULED will do better in the future, the first is ULED to do more of the number of partitions, only more detailed partition, The display will be more perfect; the second is slim, the future ULED TV will be more and more thin.
                            For the increase in the number of backlighting, Yang Jia that the most difficult is a trade-offs, for example, more partitions, high brightness, there will be heat, power problems, product reliability will decline, the major color TV enterprises for Partition control differences are often reflected in these places, and Hisense's advantage is over the years on the entire LCD backlight control technology research and development, which is well aware of the design and cost control, and therefore the achievements of Hisense in the field of television backlight control leading position.
                            For OLED TV, Yang Jia believes that both at this stage whether it is white OLED or RGB OLED has a fatal problem.
                            RGB OLED performance are good, but the big picture of the yield is too low, which is why Samsung to give up big-screen OLED, and the main reason for small screen OLED.
                            The white OLED has a fatal problem is due to add a layer of color filter film, there are a lot of light film to block, and thus OLED TV's light efficiency will drop, if you want to do high brightness, then the power consumption will be particularly large , Life will be a significant decline; but if the control power consumption, then the brightness must not be too high, which is why we see white OLED TV black no problem, and make it difficult.
