Previously, we explained the LCD screen backlight layer. This article will explain the dimming technology used in the backlight layer and the closely related HDR technology.
1. What is HDR?
The abbreviation HDR refers to High Dynamic Range, a technology that allows display screens to display the different portions of your image (bright to dark) at different brightness levels. HDR achieves higher brightness dynamic range that results in greater immersion of the visual experience to images that are closer to real life scenes. With HDR, you see more details that you wouldn’t in shadows or highlights, with a result that’s overall crisper. Further, these technologies are commonly used together, notably Wide Colour Gamut (WCG). This combination more than doubles the range of colours that a display can display, providing more vibrant, truer to life colours. By working together, HDR and WCG give the display the power to do over a billion colour variations — to make the visuals really rich and really vivid, and it really comes to life when watching movies, playing video games and looking at high quality photos.
