This study aimed to developed a defect detection system for a segment-type display module panel.

The system included a data acquisition card, a video camera, a computer and a display module on a testing table. The video camera captured the display pattern of the display module and transferred it to the computer through the data acquisition card. The dynamic multi-thresholding method and analysis as well as back propagation neural network classification was used to classify the detected defects.

The threshold values for the brightness at different positions in the display module image were obtained using the neural network and then stored in the look-up table, using two to six matrixes.

The recognition speed was faster and the system was more flexible in comparison to the previous system. The proposed method, using unsophisticated and economical equipment, was also verified as providing highly accurate results with a low error rate.

This study aims to examine the effect of self-construal on solo dining intentions and its underlying mechanism through consumer emotions. Furthermore, the study also investigates the moderating effect of the composition of other diners on the relationship between self-construal and solo dining intentions.

A 2 (self-construal: independent vs interdependent) × 2 (other diners: solo diners vs social diners) between-subjects experimental design was adopted to test the hypotheses. The data were collected from 317 Chinese consumers, followed by an analysis using IBM SPSS 23.0 and AMOS 23.0.

The findings indicate that consumers with an independent self-construal are more likely to have the intention to dine alone at a restaurant. Nevertheless, this effect is contingent upon the composition of other diners. The effect is significant only when nearby diners are social diners, and perceived enjoyment partly mediates the relationship. Conversely, when nearby diners are also solo diners, consumers' self-construals do not significantly affect their solo dining intentions. Moreover, the results indicate that consumers generally experience low levels of perceived stress when dining alone.

This study incorporates individual personality traits into research on solo diners and highlights the crucial role of positive emotions in solo dining, which provides insights for relevant enterprises to develop effective marketing strategies.
