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.)

D71, Test Method of PDP Tone and Color Reproduction limits the application to PDP (Plasma Display Panel) products. But PDP is not an FPD product being produced anymore. Therefore, it is necessary to update the document’s scope to follow the current technology trends. In this major revision, the items to be changed are as follows.

1. Title: Test Method of Tone and Color Reproduction for Flat Panel Displays
2. Update Reference Standards and Documents according to the new title
3. Update test patterns and equations to harmonize with other SEMI FPD standards (D076-00-0318 and D082-00-0821)
4. Editorial changes to the test method and related data

Through the revision of these items, it is expected that the test method oftone and color reproductionfor contemporary FPDwill be reflected,and some equations will be updatedto provide customers with tone and color reproductionaccuracy.

b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: FPD panel manufacturing companies and FPD panel purchasing companies

c. Estimate technical difficulty of the activity.
I: No Difficulty - Proven concepts and techniques exist or quick agreement is anticipated

2. Scope:
a: 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 revise the title and update the test patterns and related equations.

1. Title:
Revise to “Test Method of Tone and Color Reproduction for Flat Panel Display” from “Test Method of PDP Tone and Color Reproduction”

2. Update Reference Standards and Documents according to the new title

3. Test patterns
Update color reference patterns to harmonize with the other SEMI FPD standards (D076-00-0318 and D082-00-0821)

4. Equations
Update equations related to chromaticity difference and color difference

5. Sentences
Update with editorial changes of the test method and related data

b: Expected result of activity
Major revision to an existing Standard or Safety Guideline

For a new Subordinate Standard, identify the Primary Standard here:

Modification of an existing part of Standard(s) or Safety Guideline(s) including Appendices, Complementary Files, and Supplementary Materials

For Standards, identify the Standard Subtype below:

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:
Note: Both a: and b: below should be checked for Revision of existing Standard(s) and Safety Guideline(s).

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 FOR ‘the 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.
