Abstract
An organic light emitting display device includes display pixels, auxiliary pixels, and a plurality of signal lines. The signal lines include data lines, auxiliary data lines, scan lines, and emission control lines. The auxiliary pixels are to be used for repairing defective ones of the display pixels. In operation, scan signals are supplied in a unit of p scan lines, A emission control signals are to be supplied in a unit of p A emission control lines, and B emission control signals are to be supplied in a unit of p B emission control lines, where p≧2.
Claims20
An organic light emitting display device, comprising:
- data lines;
- auxiliary data lines;
- scan lines and emission control lines crossing the data lines and the auxiliary data lines;
- display pixels at corresponding intersections of the data lines, the scan lines, and the emission control lines;
- auxiliary pixels at corresponding intersections of the auxiliary data lines, the scan lines, and the emission control lines;
- and
- auxiliary lines connected to the auxiliary pixels, wherein scan signals are to be supplied in a unit of p scan lines, A emission control signals are to be supplied in a unit of p A emission control lines, and B emission control signals are to be supplied in a unit of p B emission control lines, wherein p≧2.
A driver, comprising:
- a generator to generate auxiliary data based on location information of a defective pixel to be repaired in a display;
- and
- a converter to adjust the auxiliary data to at least partially compensate for at least one of a wire resistance of an auxiliary line coupled to an auxiliary pixel circuit or a parasitic capacitance of the auxiliary line, wherein the generator is to generate the auxiliary data based on a repair control signal for the defective pixel.
