Introduction

In order to standardize the measurement and detection of energy efficiency of computer monitors that implement energy efficiency labeling management, according to The requirements of JJF 1261.1-2017 "Measurement and Inspection Rules for Energy Efficiency of Energy-Using Products" revise this specification. This specification replaces JJF 1261.6-2012.Compared with JJF 1261.6-2012, except for editorial modifications, the main To change as follows. ---Adjusted the specification name, scope of application, referenced documents and terminology; ---Delete the brightness consistency requirements and measurement methods; --- Deleted the energy efficiency requirements and measurement methods of CRT monitors; --- Divide LCD displays into standard displays and high-performance displays, and put forward different energy efficiency requirements; --- Added sleep state power energy efficiency requirements and measurement methods; ---Change the off-state energy consumption to off-state power, and adjust the limit value requirements; --- Added horizontal viewing angle, intrinsic resolution and color gamut requirements and measurement methods for high-performance displays; --- Added external power supply energy efficiency requirements and measurement methods for displays using external power supplies; --- Adjusted the measuring equipment; --- Adjusted the measurement uncertainty requirements and evaluation examples; ---Adjusted the original record format and test report format. The previous releases of this specification are as follows. ---JJF 1261.6-2012. Measurement and detection rules for energy efficiency of computer monitors

1 Scope

This specification stipulates the measurement requirements, testing conditions, Test items and methods, test result evaluation and test report, etc. This specification applies to liquid crystal displays used for computers, and also to computer displays whose main function is A display device for a tuner/receiver. This specification is applicable to the measurement supervision and testing of display energy efficiency, and entrusted testing can refer to this specification. production and Units that sell display products can also refer to this specification for testing. The monitors to be tested should be products that have passed the self-inspection of the producer, or commodities imported and sold by the seller.

2 References

This specification references the following documents.

3 Terminology and units of measurement

The following terms and units of measurement apply to this specification. 3.1 Off state offmode The monitor is connected to the power supply, and the power switch of the monitor is "OFF". Note. The power switch includes soft switch and hard switch. 3.2 Sleep state sleepmode A power-saving state in which the monitor does not display an image unless it is turned off. This state can be entered by the user, or by Automatically enter after a period of time without signal input. It can enter the working state through connecting equipment or user operation. 3.3 energy efficiency energy efficiency Under the conditions specified in this specification, the ratio of the luminous intensity of the display screen to the input power, the unit of measurement is cd/W. 3.4 Off state power powerofoffmode The power of the display in the off state, the unit of measurement is W. 3.5 sleep state power powerofsleepmode ......
