Abstract
An apparatus for controlling an EL drive voltage for a display panel is disclosed, which includes a current sensing circuit configured to detect an EL drive current signal outputted to the display panel, and convert the EL drive current signal into a first voltage signal, a signal generation circuit configured to generate a pulse signal based on the first voltage signal, a current protection circuit configured to generate a first control signal based on the first voltage signal and a reference voltage, and a signal coupling circuit configured to output, based on the first control signal, the pulse signal or a low level signal as a second control signal to control the EL drive voltage. According to the embodiments of the present disclosure, the EL drive voltage of the display panel can be dynamically controlled, and be reset to normal when it is overhigh.
