This section is GB/T Part 518 910, equivalent uses 61747-5 IEC . Part 5 "LCD display and solid state 1998
Score. Environmental, endurance and mechanical test methods "(in English).
For ease of use, this section made the following editorial changes.
a) instead of as a decimal by decimal comma ",". ",";
b) Remove the preface international standards;
c) cancel the references in Chapter 2 of "IEC 60747-5 and its supplement" and has a corresponding national standard IEC standards change
As the national standard;
d) All the tables are added to the number table in Appendix A;
e) Remove all 1.4 (860mbar ~ 1060mbar);
f) The original Annex A is informative appendix, its content is relevant references table, the file listed in the table not referenced in this section,
Therefore, to remove the appendix.
Appendix A of this section is informative appendix.

Liquid crystal display devices and solid state
Part 5. Environmental, endurance and mechanical test methods
1 Overview
1.1 Scope
GB/T 18910 in this section lists the test methods for liquid crystal display device, as far as possible while taking into account specified in IEC 60068
Environmental test methods.
This section also includes a visual inspection methods and the LCD module.
Note 1. This section is extracted from IEC 60749 out of, because the liquid crystal display technology is completely different from the semiconductor device, for example.
--- Shape and size;
--- Use of materials and structures;
---Features;
---Measurement methods;
---working principle.
Note 2. The device includes an LCD screen and modules.
The purpose of this section is to evaluate the environmental performance of the liquid crystal display device, to determine the preferred uniform test methods and stress level preferred value.
When this section if inconsistent with the relevant regulations should be based on relevant norms prevail.
