Abstract
An organic light emitting diode (OLED) display with improved long range uniformity is disclosed. The OLED display includes an OLED, a first transistor for transmitting a data signal of a voltage level in response to a current scan signal, a second transistor for generating a driving current of the OLED according to the data signal of the voltage level transmitted by the first transistor, a first capacitor for storing the data signal of the voltage level transmitted to the second transistor, and a second capacitor for shielding parasitic capacitor between a gate electrode of the second transistor and a cathode of the OLED.
