Abstract: A display circuit includes a plurality of current source branches and a plurality of pixel branches. Each current source branch includes a first transistor and a control circuit. Each pixel branch includes a second transistor, a pulse width control switch transistor, and a pixel unit that are connected in series. The turned-on first transistor and the turned-on second transistor form a current mirror structure. In the current mirror structure, there is a proportional relationship between a current flowing through each of the plurality of first transistors and a current flowing through the turned-on second transistor. Whether each first transistor is turned on is controlled through the control circuit, to adjust a value of the current flowing through each pixel unit through the second transistor.
