VESA, or the Video Electronics Standards Association, said the new ClearMR Compliance Test Specification is applicable to both LCD and emissive display products, including display panels, TVs, monitors, and computers with embedded displays, such as all-in-ones, laptops, notebooks and tablets.
According to VESA, the standard relies on a metric known as the Clear Motion Ratio (CMR), a numerical value based on the ratio of clear pixels to blurry pixels.
VESA said the ClearMR logo will allow consumers to easily compare the amount of motion blur between VESA Certified ClearMR displays.
The new standard replaces Motion Picture Response Time (MPRT) and other methods of blur characterization, which VESA said do not accurately reflect the true nature of blur.
"With ClearMR, VESA is providing the electronics industry with an open standard that gives consumers the confidence in knowing that they are purchasing a TV, notebook or monitor that meets the most well-defined set of blur criteria," said Dale Stolitzka, senior principal researcher at Samsung Display's America R&D Lab and lead contributor to ClearMR. "Backing VESA's ClearMR standard with a logo program will enable buyers to feel confident that they're getting a display with the clearest depiction of action for the utmost in viewing pleasure."
According to VESA, current methods of motion blur such as MPRT are ineffective because “a solely time-based metric cannot account for a number of image enhancement and blur mitigation techniques, such as excessive overshoot and undershoot, which can create artifacts and distortions that negatively impact image quality.”
VESA's ClearMR standard will limit the use of these enhancement techniques during testing—enabling consumers to make a fair comparison of motion blur quality across VESA Certified ClearMR display products.
Products undergoing ClearMR certification will be tested using a digital high-speed camera, which takes pictures of a test pattern moving across the screen as it changes from one frame to the next. A luminance measuring device, such as a colorimeter, is used to verify pattern luminance with the pictures compiled into a profile and analyzed to provide a repeatable and objective CMR value.
VESA said that display vendors wishing to participate in the VESA Certified ClearMR logo program can send their products for testing at any of VESA's approved Authorized Test Centers (ATCs).
