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.)
A flexible display is a display which is flexible or freeform surface essentially. Recently, there has been a growing interest from consumer electronics manufacturers included e-readers, smart phones, wearable electronic devices and other consumer electronics. Many of paper-like electronic display devices are based on electrophoretic, electrowetting or OLED technologies. It is found that Implementation of OLED flexible displays saw significant growth in the last few years.
According to the report of OLED display forecast 2015-2025 by IDTechEx, the next evolution is plastic and flexible displays and the market for plastic and flexible AMOLED displays will rise to $16bn by 2020. In contrast to the level of flicker visibility is well defined in flat-panel-displays, flexible display makers are in an urgent need of the methods of flicker measurement for the freeform surface in terms of flicker-free displays. Hereby, new methods of measuring overall flicker and local flicker are proposed to quantify the flicker visibility of the flexible displays.
b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information:
c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible
Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:
To standardize the test methods for measuring the flicker visibility of flexible electronic displays.
Current main methods of flicker measurement for flat-panel displays are listed as follows:
1. EIAJ ED-2522 Methods for matrix liquid crystal display modules (1995).
2. ISO 9241-305:2008 Ergonomics of human-system interaction. Optical laboratory test methods for electronic visual displays (2008).
3. ICDM IDMS version 1.03 (Chapter 4.5; Chapter 10.5; Chapter 10.6 and Chapter 12.6) (2012).
b: Expected result of activity
New Standard or Safety Guideline (including replacement of an existing Standard or Safety Guideline)

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline
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
for special procedures to be followed.
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:
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:
