Patent attributes
A pixel structure driven by a scan line and a data line arranged on a substrate is provided. The pixel structure includes a control unit, an OEL unit and a semi-transparent reflector structure. The control unit driven by the scan line and the data line is arranged on the substrate. The OEL unit is arranged on the substrate and includes a transparent electrode, a light-emitting layer and a metal electrode. The transparent electrode is electrically connected with the control unit. The light-emitting layer is disposed on the transparent electrode. The metal electrode is disposed on the light-emitting layer. The semi-transparent reflector structure is sandwiched between the substrate and the OEL unit, and includes at least a plurality of first and second dielectric layers. The first and second dielectric layers are alternately stacked, and the refractive index of the first dielectric layers is different from that of the second dielectric layers.
