Apparatus of transmitting and receiving signal, source driver of receiving status information signal, and display device having the source driver

A source driver comprising:

• a receiving controller receiving a first status information signal and outputting a second status information signal;
• and
• a receiving circuit receiving a transmission signal in response to the second status information signal and recovering the transmission signal to receiving data, the receiving controller comprising:
• a transition detection circuit detecting a transition of the first status information signal and outputting a transition detection signal;
• a delay circuit delaying the transition detection signal by a predetermined time and outputting a delay detection signal;
• and
• an output circuit receiving the first status information signal and outputting the second status information signal in response to the delay detection signal.

A display apparatus comprising:

• a display panel comprising a plurality of gate lines, a plurality of data lines, and a plurality of pixels each being connected to a corresponding gate line among the gate lines and a corresponding data line among the data lines;
• a gate driver driving the gate lines;
• a source driver driving the data lines;
• and
• a timing controller controlling the gate driver and the source driver in response to a control signal and an image input signal, converting the image input signal to a transmission signal, and transmitting the transmission signal and a first status information signal to the source driver, the source driver comprising:
• a receiving controller receiving a first status information signal and outputting a second status information signal;
• and
• a receiving circuit receiving the transmission signal in response to the second status information signal and recovering the transmission signal to receiving data, the receiving controller comprising:
• a transition detection circuit detecting a transition of the first status information signal and outputting a transition detection signal;
• a delay circuit delaying the transition detection signal by a predetermined time and outputting a delay detection signal;
• and
• an output circuit outputting the first status information signal as the second status information signal in response to the delay detection signal.
