Abstract
A display panel module, organic light-emitting diode (OLED) display and method of driving the same are disclosed. In one aspect, the module includes a display panel divided into a first portion and a second portion and a plurality of scan and data lines divided into groups arranged in the first and second potions. The module further includes a first scan driver configured to sequentially apply scan signals to each of the first and second scan line groups. The first scan driver is further configured to substantially simultaneously apply the scan signals to corresponding scan lines of the first and second scan line groups. The module also includes a first data driver configured to output first data voltages to the first data line group and a second data driver configured to output second data voltages to the second data line group with the same timing as the first data driver.
