Display driving circuit, display device including the same and electronic device including display device

A display driving circuit comprising:

• a timing controller configured to generate a reference voltage,
• a first sense amplifier configured to output a first measurement reference voltage corresponding to a first data line among a plurality of data lines,
• a second sense amplifier configured to output a second measurement reference voltage which is lower than the first measurement reference voltage in response to a second data line disposed next to the first data line, the second sense amplifier including a first input terminal configured to receive the second measurement reference voltage;
• wherein the second measurement reference voltage is less than the reference voltage, and
• a defect detection circuit connected to the second sense amplifier and configured to generate a shutdown signal based on a comparison result between an input voltage received from the second sense amplifier and the reference voltage when the comparison result has a value less than the reference voltage.
