Liquid crystal display device
Part 10-2.Environment, durability and
Mechanical test method environment and durability
1 Scope
This part of GB/T 18910 specifies the test method for liquid crystal display devices, and at the same time, as far as possible
Environmental test methods.
Note. Devices include screens and modules.
The purpose of this section is to evaluate the environmental performance of liquid crystal display devices, to determine a unified preferred test method and stress level preferred value.
If this part is inconsistent with the relevant specifications, the latter shall prevail.
