Drive device of light emitting display panel

A drive device of a light emitting display panel in which a large number of self light emitting elements are arranged as display pixels in a matrix pattern, characterized by comprising

• a monitoring element which can extract a voltage value which corresponds to the forward voltage of the self light emitting elements arranged in the light emitting display panel,
• a power supply section in which a power supply voltage which is given to the light emitting display panel is controlled based on the voltage value which corresponds to the forward voltage obtained from the monitoring element,
• a current consumption detection section which detects a current consumption value in the display panel which is driven by the power supply voltage provided from the power supply section, and
• a drive ratio control section which regulates a progression rate of aging in the monitoring element by controlling current which is applied to the monitoring element in response to the current consumption value detected by the current consumption detection section.
