A new calibration technique for improving the accuracy of chromaticity and luminance values obtained from a tristimulus colorimeter has been developed. Matrix manipulations similar to ASTM standard practice E 1455 are applied with a goal of minimizing the errors in x, y, and Y measurement, rather than those of the tristimulus values X, Y, Z.
Display calibration is the process of using the display’s controls to calibrate the on screen image so that it matches the original source content, as its creator designed it. This allows the calibrated display to accurately reproduce the video signals from any source device, be it a digital signage player, cable box, satellite box or Blu-Ray player.
According to Readings on Color, colorimetry is defined as “The science of measuring color and color appearance. Classical colorimetry deals primarily with color matches rather than with color appearance as such.
This presentation describes our complete line of testing systems for display measurement and was originally shown at SID Display Week 2012.
Gamma Scientific to Showcase Spectrophotometer for Testing Optical Coating Reflection on Displays at SID Display Week 2012
High speed spectrophotometer system for testing thin film optical coating reflection on displays. Integrates with production line equipment for high speed testing and maximum uptime.
We hope everyone is off to a great start in 2012. Enjoy these links from a busy first week of the year in light measurement and led testing.
