"4K and HDR" picture looks very good: film source or flawed

Since the advent of smart TVs, the TV market has ushered in a peak period of smart experience development. Each TV brand has launched its own UI interface, and in the past two years, with OLED technology, quantum dot technology and HDR technology. The appearance of television technology seems to have evolved from intelligent systems to the optimization of image quality. Although these technologies have their own characteristics, they all have a significant improvement in picture performance. However, some of these technologies require the support of a film source to achieve this.


4K Ultra HD resolution, pixels, four times the fine picture of full HD resolution (1920*1080 pixels), how beautiful technology. Yes, ultra-high definition resolution can make the details clearer and more vivid, but also make the actor's face look like a complete show (actors and makeup artists probably hate 4K ultra-high resolution), and most importantly, such a high resolution The rate allows large screens and high image quality to exist at the same time.

Another technology mentioned this time is the HDR technology popular with TV manufacturers at the 2016 CES show. Simply put, HDR technology can enhance the brightness of the screen while increasing the brightness and darkness of the screen, allowing the screen to be less affected by the ambient light, and making the details of the screen brighter and darker. At the same time as the brightness of the screen is improved, some screen details will not appear. Over exposure phenomenon. It can be said that HDR technology and Ultra HD resolution allow us to see more details of the picture.

Of course, we are also optimistic about the two technologies. However, don't be too happy that it is not that you buy a TV with ultra HD resolution or HDR technology that you can enjoy as much as you like, because the implementation of these two technologies requires video source support. In other words, if you buy a TV with an ultra-high resolution, you need to watch the ultra-HD source at the same time to truly experience the super-high definition quality. what? How do you say UHDTV watching Gehua? Advise you to still wash and sleep.

The same is true for HDR technology. The HDR-enhanced image quality requires the playback of video sources that support HDR technology. Therefore, if you really want to experience the fine picture quality of 4K and HDR, you need to wait for users to wait until the ultra-HDR HD video becomes popular. However, in terms of the current state of the film source, it is clear that TV technology is far ahead of the source of the film. Development situation.
