Abstract
An organic light emitting display device includes a display area and a non-display area. The display area includes display pixels at crossing areas of data lines, scan lines, and emission control lines. The non-display area includes auxiliary pixels at crossing positions of auxiliary data lines, scan lines, and emission control lines. The display device also includes a scan driver to supply scan signals to the scan lines, a first data driver to supply data voltages to the data lines, a second data driver to supply an auxiliary data voltage to the auxiliary data line, and a demultiplexer between the data lines and the first data driver.
Claims14
An organic light emitting display device, comprising:
- data lines and auxiliary data lines;
- scan lines and emission control lines crossing the data lines and the auxiliary data lines;
- a display area including display pixels at crossing areas of the data lines, the scan lines, and the emission control lines;
- a non-display area including auxiliary pixels at crossing positions of the auxiliary data lines, the scan lines, and the emission control lines;
- a scan driver to supply scan signals to the scan lines;
- a first data driver to supply data voltages to the data lines;
- a second data driver to supply an auxiliary data voltage to the auxiliary data lines;
- an auxiliary circuit between the auxiliary data lines and the second data driver;
- and
- a demultiplexer between the data lines and the first data driver, wherein the auxiliary circuit includes q auxiliary transistors connected between one or more of the auxiliary data lines and the second data driver, where q is a positive integer.
