Document Number: 6586
SNARF for: New Standard: Test Method for Motion Blur of Laptop Displays

Originating Global Technical Committee: Flat Panel Display (FPD) - Metrology
Originating TC Chapter: Korea
Task Force (TF) in which work is to be carried out: Perceptual Image Quality
Note: If a new task force is needed, also submit a task force organization form (TFOF)

1. Rationale:
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.

b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information:
Anyone evaluating laptop display characteristics

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

6. Intellectual Property Considerations:
a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:
the use of patented technology is NOT required.

If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:

b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):
there is no known material patented technology necessary to use or implement the Standard(s) and Safety Guideline(s)

c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:
the incorporation of Copyrighted Item will NOT be required

NOTE FORthe use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations 16 must be followed.

NOTE FORwill incorporate Copyrighted Item’: A copyright release letter must be obtained from the copyright owner prior to publication.
