This study explores the Chinese digital reading performance of college students in Taiwan. Two independent variables adopted are display sizes (i.e., D, 5 vs. 7-inches) and text-background color types (TBCT, positive vs. negative polarities). The results revealed that: (1) the independent variable of D has the most considerable influence on students' reading performance. The students had a shorter reading time with 5-inch than 7-inch display. (2) The comparison of reading time found that positive polarity was less than negative polarity. (3) The interaction effect between D and TBCT showed that positive polarity is less than negative polarity on the 5-inch display. No significant difference in the reading time between both polarities on the 7-inch display. (4) The students were more satisfied with the 5-inch than the 7-inch display, and with positive than negative polarity. (5) The SUS score showed that the 5-inch display had better system usability.
