摘要： An apparatus for driving an electrochromic device (ECD) includes a driving volt age output unit for selectively applying a coloring or decoloring voltage between upper and lower electrodes of an ECD; a timer for counting an applying time of the coloring or decoloring voltage in a memory type driving mode and then outputting a voltage application completion signal after the counted time exceeds a preset time, the timer bypassing the counting operation in a non-memory type driving mode; and a driving controller for selectively inputting a coloring or decoloring signal to the driving voltage output unit such that the driving voltage output unit is controlled to output a coloring or decoloring voltage corresponding to the signal, the driving controller receiving the voltage application completion signal to stop the input of the coloring or decoloring signal. Thus, memory type and non-memory type ECDs may be driven automatically using only one apparatus.
