Abstract
An electroluminescent display and a method of driving the same are disclosed. In one aspect, the display includes a display panel including a plurality of pixels configured to operate based on a first power supply voltage having a negative voltage level. The display panel is configured to generate at least one feedback voltage corresponding to an ohmic drop of the first power supply voltage. An analog-to-digital converter is configured to generate at least one digital feedback signal based on the at least one feedback voltage. An adaptive voltage controller is configured to generate a voltage control signal based on input image data, the at least one digital feedback signal, a distribution of the input image data and the ohmic drop of the first power supply voltage. A voltage converter is configured to generate the first power supply voltage based on an input voltage and the voltage control signal.
