This document replaces GB/T 18910:1-2012 "Liquid Crystal Display Devices Part 1: General Specification" and is consistent with GB/T 18910:1-2012:
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Deleted the relevant contents about IEC Q and QC (see 4:1, 5:3, 5:4, 5:5, 5:6,
5:7:3:4, 5:7:6);
b) The qualification for appraisal and approval has been deleted (see 5:2 of GB/T 18910:1-2012);
c) Change "Note 2" and "Note 3" in 6:3:1 to the main text (see 6:3:1, 6:3:1:1 of GB/T 18910:1-2012);
d) Mechanical tests were added (see 6:5):
This document is equivalent to IEC 61747-1-1:2014 "Liquid crystal display devices Part 1-1: General specifications":
The following minimal editorial changes were made to this document:
---The name of the standard is changed to "Liquid Crystal Display Devices Part 1-1: General Specification":
--- Because 6:2:2 in IEC 61747-1-1:2014 is for dimensions, 6:2:2:2 is for marking durability, 6:2:2:3 is for conditions, and 6:2:2:4 is for initial
Inspection and final inspection, 6:2:2:3 and 6:2:2:4 are about the durability of the sign: There is an error in the editing, so delete "6:2:2:1 Overall
Change the clause number and title of "6:2:2:2" to "6:2:3", "6:2:2:3" to "6:2:3:1", and "6:2:2:4" to "6:2:3:2":
