Abstract: The present application provides a display driving circuit and a method for testing drivers thereof, which is applied to a control circuit for testing a first and a second driver connected in series. The control circuit transmits an enable signal, a first voltage level, and a second voltage level to the first driver for comparing a first returned voltage level and a second returned voltage level of the first driver with a first preset parameter and a second preset parameter. When the first returned voltage level is not equal to the first preset parameter or the second returned voltage level is not equal to the second preset parameter, the control circuit stops testing. Thereby, by using the voltage levels transmitted between the control circuit and the drivers, built-in self-tests may be performed, which simplifies the self-tests of the display driving circuit and no external testing device is required.
