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":
