Abstract
An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a display unit and a plurality of pixels over the display unit. Each of the pixels comprises first and second sub-pixels each comprising an OLED and a pixel circuit. Each pixel circuit is connected to a first node and a first control line that is configured to supply a first control signal having a rising edge prior to a time when the OLED emits light in a frame. Each pixel circuit is further connected to a second node and a light emitting signal line that is configured to supply a light emitting signal having a falling edge prior to a time when the OLED emits light in the frame. The pixel circuit of the first sub-pixel comprises a first timing compensating capacitor connecting the first node and an anode of the OLED.
