PIXEL AND ORGANIC LIGHT EMITTING DIODE DISPLAY USING THE SAME

摘要

A pixel and an organic light emitting diode (OLED) display using the pixel are disclosed. The pixel includes a driving transistor for transmitting a driving current, an OLED configured to receive a first portion of the driving current and a bypass transistor configured to receive a second portion of the driving current.

主权项

1. A pixel, comprising:
an organic light-emitting diode (OLED); a driving transistor configured to transmit a driving current to the OLED, wherein the driving transistor has a gate electrode connected to a first node and wherein the driving transistor is connected between a second node and a third node; a switching transistor connected between a data line and the third node and having a gate electrode connected to a corresponding scan line; a storage capacitor connected between the first node and a first voltage line; a compensation transistor connected between the first node and the second node and having a gate electrode connected to the corresponding scan line; a first emission control transistor connected between the first voltage line and the third node and having a gate electrode connected to a light-emitting control line; a second emission control transistor connected between the second node and the OLED and having a gate electrode connected to the light-emitting control line; a reset transistor connected between the first node and a second voltage line and having a gate electrode connected to a previous scan line; and a bypass transistor connected between an anode electrode of the OLED and the second voltage line and configured to be turned off, wherein a portion of the driving current is configured to flow via the turned-off bypass transistor.
