Abstract
The disclosure discloses a driving circuit and a display apparatus, wherein the driving circuit includes a substrate circuit and at least one standby circuit, and the at least one standby circuit is connected with the substrate circuit; the substrate circuit includes a first light-emitting device, a first driving unit and a first capacitor unit; the first driving unit is respectively connected with the first light-emitting device and the first capacitor unit; the first capacitor unit is charged through the first driving unit until a voltage value of the first capacitor unit meets a compensation voltage value of the first driving unit; after the charging of the first capacitor unit is completed, a first reference potential is coupled with the first capacitor unit to enable the first driving unit to obtain an adjustable trans-voltage, and the first driving unit outputs a stable current according to the adjustable trans-voltage to drive the first light-emitting device to work. The disclosure improves the brightness uniformity problem caused by voltage drop, thereby improving the picture quality of the display.
