Did You Know VESA DisplayHDR Standards Exist for LCD and OLED Displays
The Video Electronics Standards Association (VESA) says 60 display products across 13 display OEMs have been released to market that have achieved DisplayHDR certification, with more expected to be introduced in the coming months. First introduced in December 2017, DisplayHDR is the display industry’s first fully open standard specifying high dynamic range (HDR) quality for LCD displays.
In addition to the growing adoption of DisplayHDR for LCD displays, including the first DisplayHDR laptops from Lenovo and ASUS, VESA is also seeing continued momentum behind its new DisplayHDR True Black standard for OLED and other emissive displays. Since DisplayHDR True Black was announced this past January, Samsung Display has introduced OLED panels for notebooks and laptops that meet the new VESA specification, while HP has launched the first DisplayHDR True Black laptop. DisplayHDR True Black addresses the need for significantly deeper black performance levels, for applications such as home theater and gaming in subdued lighting environments.
VESA’s latest display interface compression standard VDC-M also recently debuted. VDC-M compression exists at various bit rates, all the way from 12 bits per pixel (bpp) to 4 bpp. Another demo will highlight the full capability of DisplayPort 1.4a to handle the transport of video content compressed with the latest version of Display Stream Compression (DSC). With DSC, multiple ultra-high-definition video streams can be transported across a single DisplayPort interface or USB Type-C connector. DisplayPort 1.4a FEC (Forward Error Correction) is used with the compressed video stream to ensure a completely glitch-free visual experience.
The DisplayHDR and DisplayHDR True Black specifications from VESA provide important benefits for manufacturers and consumers alike. For PC makers, the standards provide consistent, measurable HDR performance parameters to support the development of their products. At the same time, consumers have an HDR rating number and logo system that is meaningful and reflects actual performance.
