Abstract
An organic light emitting diode (OLED) display device is disclosed. In one aspect, the OLED display device includes a driver that receives image data and generates a data signal and a scan signal corresponding to the image data, and an organic light emitting display panel that receives the data signal and the scan signal and displays an image corresponding to the image data, wherein the scan signal includes a scan-on period and a scan-off period, and when gray scales of the image data increase, the length of the scan-on period increases.
Claims20
An organic light emitting diode (OLED) display device, comprising:
- a driver configured to receive image data sequentially corresponding to a plurality of frames and generate a data signal and a scan signal corresponding to each frame, the image data of at least two frames having different gray scales;
- and
- an organic light emitting display panel configured to receive the data signal and the scan signal and display an image corresponding to the image data,
- wherein the scan signal includes a scan-on period and a scan-off period, and when the gray scale of the image data for a selected frame changes relative to the gray scale of the image data of another frame, the length of the scan-on period of the entire selected frame changes in relation to the change in the gray scale of the image data for the selected frame.
An organic light emitting diode (OLED) display device, comprising:
- a driver configured to receive image data sequentially corresponding to a plurality of frames and generate a plurality of data signals and a plurality of scan signals corresponding to each frame, the image data of at least two frames having different gray scales;
- and
- an organic light emitting display panel that includes a plurality of data lines to which the data signals are applied and a plurality of scan lines to which the scan signals are applied and crossing the data lines,
- wherein each of the scan signals includes a scan-on period and a scan-off period, each of the scan lines includes a first group, which is a set of the scan lines consecutively arranged, the organic light emitting display panel includes a first region in which the scan signals applied to the first group, and when the gray scale of the image data in the first region for a selected frame decrease relative to the gray scale of the image data in the first region of another frame, the length of the scan-on period of the scan signal transferred to the first group of the entire selected frame decreases in relation to the change in the gray scale of the image data in the first region for the selected frame.
