A pixel capable of preventing abnormal light emission thereof. A pixel includes an organic light emitting diode coupled between a first power source and a second power source; a pixel circuit unit having a driving transistor coupled between the first power source and the organic light emitting diode to supply driving current to the organic light emitting diode during a light emitting period; and a bypass unit coupled between the pixel circuit unit and a bias power source, the bypass unit being turned on during a non-light emitting period in which the driving transistor is turned off.

An organic light emitting display is disclosed. The organic light emitting display has a test pixel which receives power from a power supply, where the voltage of the power is adjusted so as to cause a certain amount of current to flow in the test pixel. The adjusted voltage is then used to power the rest of the pixel array of the display.

The invention relates to a method for controlling walking of humanoid bipedal walking robot. More specifically, the invention comprises steps of designing a zero momentum position (ZMP) of a robot for the ground surface (a); calculating trajectories of a center of gravity (COG) of the robot along with the trajectory of the ZMP (b); calculating an angular velocity of driving motors of two feet, which has the robot walk according to the trajectory of the ZMP (c); and controlling walking of the robot by driving the driving motors according to the angular velocity of the driving motors calculated above. The robot walking control method according to the invention has stability against disturbances.
