What are the technical high dynamic range HDR? Find out about the latest technology in TV screens
The idea of television innovation, in essence, on a quest to make viewers feel that the images displayed on the screen is quite realistic and matching to what can be seen in the real world.
This requires cooperation in all areas of the subject, such as the need for more accurate video cameras recording studios and the possibility of production in more control over brightness, contrast, color and highlight the images that will be displayed on the screens related.
Channels as you need to find a way to transfer all that information through an agreed standard, in addition to the necessity to provide the manufacturers of boards and algorithms best offer to help the industry partners to provide the best we can.
And it found many ways to improve the quality of the image, such as UHD resolution, or what is known as 4K, which allowed more Alpesclat within the screen.
New technology that allows to improve the quality of the images displayed as they present a technique High Dynamic Range or what is known simply as HDR , which helps to produce the best quality Pesclat.
HDR technique allows to improve the brightness and color accuracy
Most TVs use lighting standards old and brightness, where most of the progress that the density of 100 lumens luminous devices per square meter, or what is known as the CRT TVs, and lose the videos produced for this much detail standards in the dark and bright colors today.
The companies worked on the development of this standard in conjunction with the progress made in various areas of technology, and many of the methods of transfer of the image so that the development be more match with the original.
And increased lighting control areas so that the most can be made whiter white and black is blacker, as well Azadt color combinations that can be displayed so that you can view more detailed colors.
It was renamed these areas as the standard Dynamic Range, or SDR, or HDR was launched on the areas of the newest colors Display Name High Dynamic Range.
And has manufacturing companies over the years, with all the bidding process for a new series of TVs, to point out that the colors used in a series of new display screens are better than previous display technologies.
It could be argued that the HDR technology pose a real difference in detail between the past and the present, and the image details get lost in the scenes of the shadows and brightness when viewed by previous technologies.
And it worked more than 30 manufacturing companies from various fields to form an alliance UHD, including production studios and networks to provide content and technology companies and manufacturing companies TVs.
And it established a group known as those companies UHDA adoption program called Ultra HD Premium, which is based on determining the technical standards for television sets and visual content and distribution channels that cater to providing the highest level of quality of the image name.
And supports TVs that carry Ultra HD Premium logo, such as SUHD TV from Samsung, HDR content.
This means technically that TVs need to meet standards such as HDR10, and brightness of the colors at least 1,000 nits and the level of blacks is less than 0.05 candle.
And it operates a wide range of content providers to move quickly to support the HDR technique, and began major content providers to provide broadcasting services with HDR.
And shows the real difference for users with the viewing experience, where HDR technology simultaneously working with the human eye in terms of focusing on the contrast in dark areas and show subtle and distinctive differences in the areas of color brighter.
