GB/T 18910.64-2025 "Liquid crystal display devices, Part 6-4: Test methods, liquid crystal display modules with dynamic backlight" is a recommended national standard issued by our country and will be officially implemented on November 1, 2025. The standard is equivalent to the international standard IEC 61747-30-4:2016, which mainly specifies the standard test conditions and methods for the Optical Properties and power consumption of active matrix liquid crystal display modules with dynamic backlight function. The standard specifies the test flow of key parameters such as luminance uniformity, contrast ratio, and Response time in detail, and specifies the dedicated test requirements for dynamic backlight adjustment functions (such as the response characteristics of luminance changing with content). As an important part of the LCD device series standard, its implementation will provide a unified technical basis for the quality control of dynamic backlight display products and promote technological innovation in the display industry.
