Abstract
There are provided an array substrate and a display apparatus. The array substrate comprises a voltage driving circuit () for driving display pixels to display images, a current sensing circuit (), and further comprises test pixels (), a current comparison circuit (), and a voltage compensation circuit (), wherein the current sensing circuit () is connected to the test pixels () and the current comparison circuit (), and the current comparison circuit () is connected to the voltage compensation circuit (); the current comparison circuit () compares the current value of the current sensed by the current sensing circuit and flowing through the test pixels () with a set threshold, and outputs the comparison result to the voltage compensation circuit (); and the voltage compensation circuit () compensates for the driving voltage of the voltage driving circuit () when the current value is smaller than the set threshold. The array substrate can compensate for the current of the display pixels to avoid occurrence of the pixel degradation.
