Abstract
Provided is a light emitting display device and a method of driving the same. The light emitting display device includes: a display panel in which pixel lines including a plurality of pixels are divided into at least one area A and at least one area B; a panel driver connected to the pixel line; and a timing controller for controlling operation of the panel driver to perform image data writing (IDW) driving for sequentially writing input image data to a plurality of pixel lines included in one of the area A and the area B and to perform sensing data writing (SDW) driving for writing sensing data to a pixel line included in one of the area A and the area B in a vertical blank period in which image data writing driving is not performed. The timing controller writes coupling compensation data during the vertical blank period. According to the present disclosure, a device can be realized in consideration of a sensing deviation that may be generated in a compensation operation for improving deterioration of elements included in a display panel and increasing the lifespan thereof.
