Provided is an optical write device and method. The optical recording method includes generating a first signal including a preset write pulse power Pm in response to information to be written, generating a second signal including an over drive pulse power Po that is synchronized with the preset write pulse power Pm and which is at a higher level than the preset write pulse power Pm, and writing the information to an optical disc using a driving signal that is obtained by synthesizing the first and second signals.

Optical recording device and method

An organic light emitting display device and a method of fabricating the same are provided. The organic light emitting display device includes a substrate, a first electrode formed on the substrate, an inorganic pixel defining layer formed on the first electrode and having an opening exposing at least a portion of the first electrode, an organic layer disposed on the first electrode and having at least an organic emission layer, and a second electrode formed on the organic layer.
