First of all, the display is a mandatory requirement for China's energy efficiency labeling. Displays sold in the country must be affixed with a qualified energy efficiency label, otherwise it is non-compliant. The energy efficiency of the display needs to meet the requirements of the GB 21520-2015 standard.

      GB 21520 is aimed at LCD monitors used as computers or computer monitors whose main function is a display device that must have a tuner/receiver.

Generally understood, it is necessary to have the signal transmission function, which can be transmitted through RS232, HDMI, etc.

      Two types of monitors: 1. Standard monitor 2. High performance monitor

      What is a standard display: When the contrast ratio is not satisfied at 60:1, the horizontal viewing angle is not less than 160° + the inherent resolution is not less than 2.7 million pixels + the color gamut is not less than 75%

      What is a high-performance display: When the contrast ratio is 60:1, the horizontal viewing angle is not less than 160° + the inherent resolution is not less than 2.7 million pixels + the color gamut is not less than 75%

 

What are the energy efficiency test items for monitors in China

      >Monitor sleep state power

      >Monitor off state power

      >Display energy efficiency rating/energy efficiency

      >External power supply monitor, the power supply should meet the requirements of GB 20943
