Abstract
A display device is disclosed that includes a display panel, a first source circuit board, a second source circuit board, and a control circuit board. The first source circuit board is configured to output a first feedback voltage corresponding to a first driving voltage. The second source circuit board is configured to output a second feedback voltage corresponding to the second driving voltage. The control circuit board is configured to supply the first and second driving voltages to the first and second source circuit boards, respectively, and receive the first and second feedback voltages from the first and second source circuit boards, respectively. The control circuit board includes a comparison unit configured to compare the first and second feedback voltages with a preset reference voltage and generate a result signal in response to a comparison result, and a generation unit configured to generate a protection signal for activating a protection mode for protecting the display panel based on the result signal.
