Stretchable display devices and methods of compensating luminance of the same

A stretchable display device comprising:

• a stretchable display panel comprising:
• a plurality of pixels;
• at least one first resistive film extending in a first direction;
• and
• at least one second resistive film extending in a second direction crossing the first direction on the stretchable display panel;
• a scan driver configured to provide a scan signal to the pixels via a plurality of scan-lines;
• a data driver configured to provide a data signal to the pixels via a plurality of data-lines;
• a row detection driver configured to detect a first current flowing through the first resistive film to generate a first detection signal corresponding to the first current;
• a column detection driver configured to detect a second current flowing through the second resistive film to generate a second detection signal corresponding to the second current;
• a compensation control signal generator configured to receive the first detection signal to detect an amount of variation of the first current, to receive the second detection signal to detect an amount of variation of the second current, and to generate a compensation control signal based on the amount of the variation of the first current and the amount of the variation of the second current;
• a timing controller configured to control the scan driver and the data driver;
• and
• a power supply configured to generate a compensated power voltage based on the compensation control signal, and to provide a power voltage or the compensated power voltage to the stretchable display panel via a plurality of power-lines.

A method of compensating luminance of a stretchable display device, the method comprising:

• detecting a current flowing through a resistive film formed on a stretchable display panel;
• generating a compensation control signal based on an amount of variation of the current;
• and
• compensating a data signal or a power voltage to be applied to the stretchable display panel based on the compensation control signal.
