Abstract
A display apparatus including: a plurality of pixels receiving data voltages in response to gate signals; a drive circuit generating a power voltage and a control signal; a gate driver operating with the power voltage, generating the gate signals and a dummy gate signal in response to the control signal, and supplying the dummy gate signal to the drive circuit; and a data driver operating with the power voltage and generating the data voltages in response to the control signal. The drive circuit measures a temperature of the drive circuit, and a voltage and a current at an output node of the drive circuit generating the power voltage. The measured temperature, voltage and current, and the dummy gate signal are stored in the drive circuit in a predetermined order. This information can be used to detect error states that the display can indicate and use to protect itself from damage.
