Source driver and display apparatus including the same

A source driver comprising:

• a digital-to-analog converter configured to receive a data signal, convert the received data signal into an analog signal, and output the analog signal;
• amplifiers configured to amplify the analog signal;
• a control signal provision unit configured to output a first control signal and a second control signal based on or in response to a first bias signal;
• a first level shifter configured to shift a level of the first control signal based on or in response to a second bias signal having a voltage greater than that of the first bias signal and to output a level-shifted first control signal;
• a second level shifter configured to shift a level of the second control signal based on or in response to the second bias signal and output a level-shifted second control signal;
• output lines corresponding to the amplifiers;
• a multiplexer configured to selectively output the amplified analog signals from the amplifiers to the output lines based on or in response to output of the first level shifter;
• a charge sharing switch connected between the output lines and controlled based on or in response to output of the second level shifter;
• and
• a protector configured to detect a voltage of the first bias signal and to turn off the amplifiers, the first level shifter and the second level shifter and output a first deactivation signal configured to turn off the multiplexer and a second deactivation signal configured to turn off the charge sharing switch, when the detected voltage of the first bias signal is less than a predetermined reference voltage.
