A pixel includes a pixel circuit to control an amount of current supplied from a first power source to an organic light emitting diode (OLED) based on a data signal. At least one first transistor is located in a current path between the first power source and OLED. A second transistor is coupled between a gate electrode of the at least one first transistor and an emission control line through which an emission control signal is supplied. The emission control line controls a state of the at least one first transistor, and the second transistor turns on or off based on the data signal.

A method of bonding a flexible printed circuit board (FPCB). The method includes disposing a bonding material on a connection unit of a panel, disposing a connection unit of the FPCB on the bonding material; disposing a thermally conductive sheet on the connection unit of the FPCB; and heating and pressing the connection unit of the FPCB onto the connection unit of the panel. The thermally conductive sheet includes through holes that are formed in the thermally conductive sheet or grooves that are formed in a bottom surface of the thermally conductive sheet. In the operation of heating and pressing the connection unit of the FPCB, extended portions of the FPCB are accepted into the through holes or the grooves in the thermally conductive sheet.

A gate drive circuit includes a plurality of stages connected one after another to each other. Each of the stages includes a charging section, a driving section, a discharging section, a holding section and a holding control section. The driving section pulls up a high level of a first clock signal to output a gate signal. The discharging section discharges a voltage potential of a first node to a first off-voltage. The holding section holds a voltage potential of the first node to the first off-voltage. The holding control section receives the first clock signal and a second clock signal. The holding control section holds a voltage potential of the holding section to a second off-voltage through a second node in accordance with the second clock signal to prevent floating of the holding section.
