Abstract
A light-emitting substrate has a light-emitting region and a test region. A plurality of light-emitting device groups and a plurality of driving circuits are disposed in the light-emitting region. The driving circuits include at least one selected driving circuit, and a selected driving circuit includes at least one first-type output terminal and at least one second-type output terminal. The first-type output terminal is electrically connected to the light-emitting device group. A power line is electrically connected to the light-emitting device groups. A first test pad and a second test pad are disposed in the test region. The first test pad is electrically connected to a second-type output terminal of the selected driving circuit, and the second test pad is electrically connected to the power line. The first test device group is electrically connected to the first test pad and the second test pad.
