This application claims priority under 35 U.S.C. §119 to and the benefit of Korean Patent Application No. 10-2012-0087896 filed in the Korean Intellectual Property Office on Aug. 10, 2012, the entire contents of which are incorporated herein by reference.
1. Field
The described technology relates generally to an organic light emitting diode display, and more particularly, to an organic light emitting diode display having a thin film encapsulation layer.
FIG. 1 is an equivalent circuit of one pixel of an organic light emitting diode display according to a first exemplary embodiment.
FIG. 2 is a cross-sectional view of the organic light emitting diode display according to the first exemplary embodiment.
FIG. 3 is a cross-sectional view of an organic light emitting diode display according to a second exemplary embodiment.
Example embodiments will now be described more fully hereinafter with reference to the accompanying drawings; however, they may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey exemplary implementations to those skilled in the art.
The drawings and description are to be regarded as illustrative in nature and not restrictive. Like reference numerals designate like elements throughout the specification.
Further, the size and thickness of each component shown in the drawings are arbitrarily shown for understanding and ease of description, but embodiments are not limited thereto.
