There are problems of low accuracy and low efficiency in manual display detection and machine detection. Thus, this paper proposes a display quality detection method of a two-screen watt-hour meter based on domain adaptation. To effectively improve detection efficiency, this paper deals with detection of quality problems such as virtual or missing welding and tin connection in the display field of an electricity meter, the driving circuit components of electricity meter display and their production processes. It detects virtual, broken and missing display and multi-display of the display field of odd and even screens. To improve the detection accuracy, local domain adaptation is used to align the source and target domains, and to extract fine-grained information in the display. The experimental results show that the method proposed in this paper improves detection efficiency and accuracy in quality detection of the LCD screen field of the electric energy meter and its driving circuit.
