What is HDR?Learn the latest technology on TV

The idea of television innovation in its essence is to strive to make viewers feel that the images shown on the screen are completely realistic and identical to what can be seen in the real world.

This requires cooperation in all areas related to the topic, such as the need for more accurate video recording cameras and the possibility of production studios to control more brightness, contrast and colors and highlight the images that will be shown on screens.

The channels also need to find a way to transfer all of this information through an agreed standard, in addition to the necessity of manufacturers to provide better display panels and algorithms to help industry partners to provide the best as possible.

There are many ways to improve image quality, such as UHD, or what is known as 4K, which allows to provide more bitch in the screen.

There is also a new technology that allows improving the quality of the displayed images, which is the high dynamic range technology, or what is known as HDR, which helps to produce better quality..

HDR technology allows to improve brightness and color accuracy

Most of the TVs today use lighting and brilliant standards, as most of these devices offer a density of 100 luminous candles per square meter or what is known as CRT TVs, and the videos produced these standards lose many details in the dark and bright colors.

The companies have worked to develop this standard in conjunction with the progress in the various fields.

The areas of lighting control increased so that the white color can be served more white and black more black, and the color collections that can be shown so that more detailed colors can be shown..

These areas were named after the standard dynamic range or SDR, and the name of the high dynamic range or HDR was launched in the fields of later color display.

And manufacturing companies for years, and with each process of a new series of TVs, indicated that the colors used in the new display series are better than previous display technologies.

It can be said that HDR technology constitutes a real difference in the details between the past and the present, and the details of the image were lost in the scenes of shadows and brightness when displayed by previous technologies.

More than 30 manufacturing companies have worked from various fields to form the UHD alliance, including production studios, networks, technology and technology companies, television manufacturers.

The group of those known as UHDA established an accreditation program called Ultra HD Premium, which is based on determining technical standards for TVs, visual content and distribution channels that meet the needs of providing the highest quality level of the image.

The Ultra HD Premium TVs, such as Samsung SUHD TV, support HDR content.

This means technically that TVs need to meet the standards such as HDR10, and that the brightness of colors is not less than 1000 candles per square meter and the black level is less than 0.05 candle.

A large group of content service providers is working quickly to support HDR technology, and the main content providers began to provide broadcasting services with HDR.

The real difference of users with the viewing experience appears, as HDR operates simultaneously with the human eye in terms of focusing on contrast in dark areas and showing slight and distinctive color differences in the areas more brighter.
