Timing controller, organic light-emitting diode (oled) display having the same and method for driving the oled display

An organic light-emitting diode (OLED) display comprising:

• a display panel including a plurality of pixels;
• a scan driver configured to provide a scan signal to the pixels;
• a data driver configured to provide a data signal to the pixels;
• and
• a timing controller configured to i) control the scan driver and the data driver, ii) determine whether the OLED display is in a failure mode based at least in part on an input signal, iii) output a multiplexed signal based at least in part on whether the OLED display is in the failure mode, and iv) selectively output the multiplexed signal of a current frame or the multiplexed signal of a previous frame based at least in part on whether the OLED display is in the failure mode.

A method for driving an organic light-emitting diode (OLED) display, the method comprising:

• receiving an input signal that includes input data and a data enable input signal;
• generating a fail enable signal to be activated based at least in part on the data enable input signal when the OLED display is in a fail mode;
• selectively outputting a multiplexed signal including one of the input signal or a fail signal, to be output in the fail mode, based at least in part on the fail enable signal;
• delaying the fail enable signal for one frame;
• and
• outputting the multiplexed signal of a current frame during an inactive period or the multiplexed signal of a previous frame during an active period of the mask signal.
