Abstract :
As many errors appear in energy efficiency inspection of display equipment due to influence of environment condition, operation, instrument and so on, based on the analysis of different errors, the evaluation of typical errors are shown in this article. Simultaneously, hardware and software for current luminance meter are redesigned and also humidity and digital temperature sensor with high precision are put into monitoring experiment condition. It is shown that the system is stable, less errors and preciser after redesigned.
