Dolby® Contrast, a Dolby high-dynamic-range (HDR) technology, makes the HDTV visual experience more compelling than ever before.

Dolby Contrast:

Enables LCD displays with true blacks, brilliant brights, and more vivid, natural colors

Provides significant power savings

Includes expert Dolby engineering support

Offers access to Dolby’s network of partners, accelerating design, development, and manufacturing

Dolby Contrast takes picture contrast and quality to new levels of depth and detail. Blacks are deeper. Whites are brighter. And every color and shade in between is more vivid. With Dolby Contrast, the viewer experience is stunningly superior to that of a conventional display.

Dolby Contrast overcomes the limitations of LCD displays by employing locally modulated LED backlighting rather than current conventional cold-cathode fluorescent (CCFL) tubes. By locally controlling each portion of the image (also known as local dimming), Dolby Contrast enables strikingly high contrast and produces details otherwise not seen on a conventional display.

In addition, Dolby helps you leverage intellectual property (IP) throughout the HDR value chain, from guiding your choice of the best manufacturing partners to utilizing the expertise of Dolby engineers for image optimization and implementation.

Dolby’s expert video engineering team has more than 100 years of television development and manufacturing experience combined. That matters, because we include engineering support with every Dolby Contrast license. Thus, you can count on us to help you manage the engineering demands that come with developing innovative products, from design through manufacturing.

Why Dolby

LCD TVs deliver a sharp, high-resolution picture. However, they have a limited dynamic range and cannot display true blacks.

Dolby Contrast overcomes both limitations. The combination of LED backlighting and proprietary local dimming technology dramatically increases the dynamic range and enables true blacks and far more detail on all other colors.

This higher contrast ratio also helps TV sets stand out on the retail floor, which is important when so many displays look so very much alike.

Further, when you choose Dolby Contrast you get a complete, end-to-end HDR solution. Dolby works with your team to speed innovative products to market, leveraging our extensive network including a portfolio of HDR intellectual property that includes seven local dimming patents, with more than 100 patents pending worldwide. Dolby also provides comprehensive engineering technical support.

While LEDs are quickly surpassing the efficiencies of CCFLs, widespread adoption continues to drive lower LED prices. As a result, Dolby Contrast offers superior image quality at a competitive cost, with the added plus of at least a 20 percent power savings (on average) compared to CCFLs when viewing typical movie content.
