HDR is an abbreviation of High-DynamicRange, meaning "high dynamic range". In the field of photography and display, the concept is not special. In fact, these two processes are the opposite: One is to increase the dynamic tolerance of the picture when drawing content, and the other is to present this highly dynamic content to the user during playback. Therefore, we can also realize that HDR technology is not a simple picture quality enhancement technology, which requires content-end support. 
Therefore, this technology is in fact the same situation as 4K. Only with 4K resolution devices, users can not feel the exquisite improvement of the screen, you must configure the 4K film source to truly experience the extreme details of the charm. HDR technology is currently developing rapidly. Major TV brands are all mentioning. However, from the current state of view, HDR technology is still somewhat technically advanced. The development of the 4K was the same, the content did not keep up, and the display terminal was widely promoted.
HDR technology needs the corresponding content
HDR technology is currently developing at a rapid rate and there are not many problems with the application of display devices. In 2015, Internet companies such as Samsung, Sony, LG, Philips, Panasonic and other upstream manufacturers, domestic millet, and LeTV, all pushed forward this concept. The technical standard of HDR gradually matures and the market is ushering in full competition. The 2016 HDR technology has also become almost a concept that all brands have mentioned. Therefore, this feature of hardware technology is no longer a gimmick. 
Compared to 4K resolution, there has been some progress in the construction of HDR content. The United States Netflix and Warner Bros. Hollywood and other content production companies have promised that their content will support HDR. Oscar winning the Academy Award for Best Machine Vision was filmed on a 4K and 8K HDR camera.
There will be more movie content supporting HDR technology in the future. However, the popularity of film HDR technology alone is not enough. When broadcasting TV programs fully popularize HDR technology is the true gospel. 
HDR technology is not simply a picture quality enhancement technology. As a complete set of technical standards from content recording, post-processing, transmission, decoding, and terminal display, HDR technology can greatly enhance our viewing experience. Without content, even if the hardware of HDR technology matures, viewers cannot experience the charm of HDR technology. Therefore, the content construction is very important, otherwise the HDR technology will become a kind of hardware that all major TV brands are mentioning.
At this year's TV conference, many brands are mentioning HDR technology. People who are familiar with this technology have an impression that this technology can effectively solve the problem of photo distortion in still photography. Many mobile phones now have HDR functionality. The HDR function of the TV is mainly designed to improve the latitude of the picture, so that the brightness and dark field performance is better. Moreover, this improvement in image quality is intuitive and intuitive, even if it is not a video geek but an ordinary audience can also distinguish with the naked eye.
Is it the old way to go 4K development with technology first HDR?
HDR technology was originally applied in photography
HDR technology makes the dark details of the screen more outstanding
HDR technology is not only a matter of hardware breakthrough but also important
