An organic light emitting diode is capable of improving light efficiency per pixel unit by forming a cathode electrode to cover an anode electrode, thereby focusing light emitted from a luminescent layer per pixel unit. An example of the method includes writing a first strip to a first storage device and a second storage device. The rotating action of the rotatable lever relatively displaces the pedal arm toward the front of the vehicle. At least one of the metal shell and the insulative housing defines a hole receiving the at least one positioning portion. The obtained dielectric ceramic has the quality factor of 160,000 and the dielectric constant of 8. The existence of an image edge component is detected.
