HDR emerged in the radio and television industry, and then gradually expanded to mobile devices. The introduction of this concept and technology in the LED display field is relatively lagging behind. Winbond, as a pioneer and early technology implementer in the introduction of HDR technology into the LED display field, aims to provide customers with a better picture quality experience.
We are in a colorful world. In order to truly present this colorful world through the display screen, humans invented cameras, video cameras, televisions and other equipment, and also developed many advanced technologies. HDR is one of them. .
The full name of HDR is High-Dynamic Range, that is, high dynamic range image technology. This technology was first applied to photography. Turning on HDR during the shooting process can make the original dark scene brighter and more transparent. Now, HDR technology has been applied to various aspects such as home appliances and smart terminals. Because of Winbond Technology, the LED display field began to truly experience the advantages brought by HDR technology.

What can HDR bring?
Take TV as an example. The range of brightness that traditional TVs can show is extremely limited, which is far from the range that human eyes can perceive. The reason is that the brightness of the traditional TV in the bright place of the picture cannot be increased, and the dark place cannot be darkened. This leads to a poor sense of layering in the final perception of the human eye, and a lot of details are lost.
HDR ultra-quality display technology can perfectly solve this problem. HDR is relative to the mainstream SDR currently on the market
1080P display technology, with higher pixel load: 3840×2160; wider color gamut range: BT2020. The same picture can display more color information and more detailed textures of the image. At the same time, with more advanced electro-optical conversion technology, the light and dark contrast of the picture is improved in all directions, so that a picture can show the most realistic appearance in all directions.

In the LED display industry, Winbond has made video processing equipment that supports HDR film source analysis, pushing LED displays into the HDR era.
HDR images show more details in bright and dark parts. To the human eye, the picture is fuller and the color transition is smoother.
As a leader in the image processing industry, SONY has announced a standard for ultra-high-definition picture quality, including improvements in 5 dimensions: resolution, color depth, color gamut, contrast, and frame rate.
The Ultra HD Blu-ray standard requires a resolution of 4K, a color depth of 10bit, and a color gamut of BT.2020. The contrast ratio is the requirement for HDR, and the frame rate is 60fps.
The high-definition Blu-ray standard stipulates that the color depth is 10bit, which means that 1.07 billion colors can be displayed.
Each color in 6Q I0 RGB has 2 to the power of 10, which is 1024 levels. There are over 1.07 billion (1024×1024×1024) color combinations in RGB tricolor.
The ordinary Blu-ray standard SDR supports 8bit color depth, with only 16.77 million colors, which is a huge gap. In other words, through the 10bit output, the color is richer and fuller, and the color transition will be smoother than that of the 8bit.
