HDR technology, or High-Dynamic Range, is a technology that can significantly enhance image quality. Initially applied in the field of broadcast television, it gradually expanded to mobile devices. By increasing the brightness range and color depth, HDR technology enables images to more realistically reproduce the vibrant world seen by the human eye.

The adoption and application of HDR technology in the LED display field have been relatively late, but this is changing. Companies like Nova, as pioneers and early adopters of HDR technology in LED displays, are driving the development of this technology and striving to provide users with superior image quality.

HDR technology brings the following advantages to LED displays:

1. Higher Brightness:

HDR technology allows LED displays to achieve higher brightness levels, making bright areas of the screen more dazzling while preserving details.

2. Deeper Blacks:

HDR technology can also handle lower black levels, allowing deeper blacks in dark areas, enhancing contrast and depth in the image.

3. Richer Colors:

Combined with wide color gamut technology, HDR can display a wider variety of colors, making the images more vivid and realistic.

Five Dimensions of Image Quality Enhancement in HDR Technology

According to industry standards, HDR technology improves five dimensions: resolution, color depth, color gamut, contrast, and frame rate. The comprehensive enhancement of these five dimensions brings a “better pixels” display effect.

HDR Industry Standards

Currently, the main HDR standards include HDR 10, HLG, and Dolby Vision. HDR 10 is the most common open standard, HLG is suitable for broadcasting, and Dolby Vision supports dynamic metadata, offering more precise color control.

HDR Requirements for Displays

Typically, an HDR display needs to meet certain technical requirements, including a peak brightness of at least 1000 nits, a minimum brightness below 0.05 nits, and coverage of more than 90% of the DCI-P3 color space.

HDR Application Prospects for LED Displays

LED displays, with their inherent advantages of high brightness and wide color gamut, are the ideal medium for HDR technology. Companies like Nova are developing control systems capable of processing HDR signals and handling fine grayscale, overcoming bottlenecks in applying HDR technology in the LED industry. As these technologies advance, the application prospects of HDR in LED displays will broaden, offering users a more stunning visual experience.
