Abstract
A display circuit includes a first control transistor and a second control transistor. A gate of the first control transistor is connected to a second scan line. A first electrode of the first control transistor is connected to an anode of a light-emitting device. A gate of the second control transistor is connected to a third scan line. A first electrode of the second control transistor is connected to a collection module. A reading signal line is connected to an ADC module, and second electrodes of the first and second control transistors of each pixel driving circuit. In a compensation stage, active levels are input into the first and second scan lines, and an inactive level is input into the third scan line. In a collection phase, an inactive level is input into the second scan line and an active level is input into the third scan line.
