It is easy to notice a poorly calibrated display… and with the explosion of digital signage, we are seeing them everywhere. There is a growing need to address proper display selection and image quality, and the Digital Signage Display Expert (DSDE) program comes to the rescue. The DSDE is the industry’s only comprehensive training program designed to address the subject of displays as a key component in a digital signage system and teaches how to properly calibrate them. The program recognizes that accuracy in transmitting images is directly related to impact and the effectiveness of the entire digital signage system.
The mandate of the DSDE program is for the attendees to understand each type of display technology, how they operate, and how they are impacted by the environment. By adopting calibration standards and understanding the methodologies involved in the calibration process, we can avoid having to settle for a poor, mediocre or inaccurate image onscreen.
The DSDE program covers the science of color, light and the human eye to understand how and what we see. We are all inundated with display specifications and we are supposed to use those as the basis for display selection but… are the specifications accurate, what do they mean, and how do they affect what we see on the screen. These are critical questions that the DSDE answers.
In order to go beyond adjustments and truly embrace calibration, we must study each display technology and type whether it is flat panel or projection. This provides a foundation of knowledge about the pros and cons of each technology but also what elements of the display are affected when we calibrate. Couple this with a tutorial on illumination and how that affects the images we see, and you are well on your way to making that “perfect picture”.
Understanding that there are different levels of digital signage applications and systems the DSDE provides two levels of calibration that can be employed. The first level is Calibration 101 -a basic calibration usable in any situation. It is a step by step process that does not require expensive test equipment. The next level of calibration is Advanced Calibration – this involves instrumentation to measure display output exactly. This is used in applications where the image must look as close as possible to the content being displayed. It is also used for video walls and display matching.
The DSDE provides the information to understand the entire calibration process and why you do what you do. By understanding the entirety of the process and employing the skills taught in the DSDE, you become part of an elite group of technicians who can really make a common display into that “perfect picture”.
