Abstract:
1. A device for driving an organic EL display having a driver and a power source for driving a display panel comprising: the driver controlling the amount of current applied to the display panel according to a control signal; the power source controlling the intensity of voltage applied to the driver and the display panel according to the control signal; and a controller controlling at least any one of the driver and the power source according to an electric signal corresponding to an intensity of external light, wherein the controller controls the driver to increase the amount of current applied to the display panel when the value of the electric signal is larger than a reference value, and the controller controls the driver to decrease the amount of current applied to the display panel when the value of the electric signal is smaller than the reference value, the reference value being any one of reference values having different current or voltage values, wherein the reference values are preset in various modes, the modes being predetermined based on an environment in which the display panel is located.
