In the era of mobile Internet, TV is gradually being marginalized, and TV manufacturers are constantly pursuing breakthrough highlights in their products. Some are turning the screen into a so-called curved screen TV, while others are focusing on image quality. When buying a TV, in addition to the brand, appearance, and function, the picture quality is a key indicator to measure the quality of a TV. How to evaluate the picture quality of a TV? Many people are accustomed to judging by color gamut, but in fact, a high color gamut does not directly indicate a good picture quality. So what kind of picture must be presented to say that the picture quality is good? What factors need to be referred to? Color volume The color rendering volume is a three-dimensional indicator. The color performance of a TV at all brightness levels is closely related to the color rendering volume. The color rendering volume measures the three-dimensional space formed by the color gamut and brightness level of the TV. The color gamut depends on the maximum number of colors that the TV can display, and the peak brightness represents the maximum brightness level of the TV. The wider the color gamut and the higher the brightness of a TV, the larger the color rendering volume. The color rendering volume perfectly integrates these indicators. The higher the color volume value, the more accurate the TV can show the color, which is the closest to the actual color. At present, QLED products with 100% color rendering volume have appeared on the market, which means that all colors within the DCI-P3 range can be displayed at any brightness. Light control performance The backlight is one of the important components in the TV display layer. Since the liquid crystal panel itself does not emit light, it needs the support of the backlight to emit visible light. But there is a special case of OLED TVs. OLED TVs can self-illuminate and do not need the support of backlight. When displaying dark parts, OLED can be completely turned off to achieve the best contrast. Except for special OLEDs, under other display technologies, the backlight is a factor that has a very large impact on the contrast of the TV screen. As long as the TV is turned on, the backlight is in working condition, even if it is displaying a black picture, the backlight is also working, which causes many TVs to display a black picture that is not ideal, the contrast is poor, and the black is slightly white. When choosing a TV, if you want the best light control processing, it must be OLED. Of course, on ordinary LCD TVs, there is also its corresponding technology, that is, multi-zone backlight adjustment, which divides the TV backlight into multiple independent zones, and the backlight of each zone is adjusted in real time according to the actual needs of the page. The image contrast is higher, even comparable to OLED. Sports performance I don’t know if you have such an experience when watching this year’s World Cup. When athletes are running fast on the field, there will always be a certain amount of tailing and jitter. It not only seriously affects the viewing experience, but also fatigue and dizziness after prolonged viewing. Therefore, sports performance is also an indispensable indicator when buying a TV. MEMC is currently the most popular technology on the market. It can complement the motion picture through the dynamic imaging system. When watching racing sports or action movies, add a motion compensation frame between the two traditional frames. Increasing the traditional 60Hz refresh rate to 100Hz ensures that the picture is very smooth and enhances the viewing experience. Even if you are watching F1 racing games, you are not afraid of screen tailing effects. Resolution The resolution of a TV can be clearly distinguished by the naked eye. Under the same size screen, the resolution means that the screen is more delicate and closer to what the human eye can see. Therefore, the resolution is also an important performance indicator of the TV. At present, 1080P is the most mainstream resolution, but the size of TVs is getting larger and larger, and it seems that 1080P is no longer enough. In the future, as 4K resources increase, 4K will become the mainstream of the market. Therefore, when buying a TV, it is best to choose 4K resolution products within the budget. to sum up In summary, when buying a TV, we can judge the quality of the picture by the color volume, light control performance, sports performance and resolution. Of course, in addition to various hard indicators, you must also refer to your subjective feelings. In offline stores, you can distinguish and compare with the naked eye, and choose a product that is more pleasing to your attention. 2 in 1 usb adapter,USB Hubs,USB Hubs 3.0,docking station usb c,best usb hubs Shenzhen Konchang Electronic Technology Co.,Ltd , https://www.konchangs.com
