Pixel unit of organic electroluminescent display

摘要

A pixel unit of an organic electroluminescent display having a light emitting area and a transparent area is provided. The pixel unit includes a scan line, a data line, a control element electrically connected to the scan line and the data line, a power line electrically connected to the control element and an organic light-emitting diode disposed inside the light emitting area and electrically connected to the power line and the control element. The power line includes a main portion and a plurality of branch portions connected to the main portion. The branch portions are disposed inside the transparent area and electrically independent from the data line. A width of each of the branch portions is identical to a minimum line width of the data line.
