High Dynamic Range (HDR) imaging technology is currently being promoted for use in liquid crystal displays (LCDs) to enhance image quality. The main goal of HDR technology is to allow viewers to experience images on their screens that are closer to real-life visual environments. Compared to standard images, HDR displays can provide a greater dynamic range and more image details, especially in the highlights and shadows, resulting in a more natural and softer visual experience.

HDR technology is a post-processing image technique. To better capture details in both bright and dark areas, the color depth requirement has been increased from the current 8-bit to 10-bit or higher. This enhancement boosts the number of grayscale levels from 256 to over 1024. The backlighting needs to incorporate local dimming technology with high brightness peak driving algorithms, requiring LED backlights with at least 128 zones. This upgrade expands the display brightness range from 0.4–500 nits to 0.05–1000 nits. Additionally, the image data must either come from native HDR sources or be upscaled from LDR (Low Dynamic Range) data to HDR data using specific algorithms.

Here is an HDR Demo Video. If you’re using an HDR-compatible device, you’ll be able to experience HDR effects. If your monitor doesn’t support HDR, you can try using a smartphone. Feel the difference between SDR and HDR for yourself.
