a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
The performance of motion blur is continuously developed at hold-type displays. The frame frequency is higher, and it is possible to perform the variable sync such as, adaptive sync, free sync and G-sync could have a VRR (variable refresh rate) function in the laptop displays.
To measure the motion blur of displays, the display should be normally connected with the signal generator to display to show a scroll pattern and synchronized with the camera, so far. But it is hard to do a display of the laptop set, because there is not a port in the laptop to connect with the signal generator to give a signal to the laptop. For that reason, in this standard, the high-speed camera to capture the display images and scroll movie contents could be displayed on the laptop display, individually, should be applied.
Based on the system, the blur characteristic of display would be captured and analyzed. The most of report is blurred edge width (BEW) or blurred edge time (BET). It is rarely to reflect the different slope of blur shape and knee of curve of rising and falling area. Even though subjective results are different, depending on the slope shapes, the result would be the same, based on the current method. It could not be the information to report the display performance.
Human eye can detect and perceive the shape of pattern, based on the different contrast. Therefore, the customized evaluation method should be considered to be suitable to the motion blur performance. In order to evaluate the high-performance display, motion blur should be measured and calculated by considering blurred width and MTF, mainly.
