Active matrix organic light-emitting-diode display backboard and manufacturing method thereof, display device

摘要

An AMOLED display backboard, a display device and a manufacturing method of an AMOLED display backboard are provided. In the AMOLED display backboard, the number of VDD lines (601) is less than that of sub-pixels in one row, thus reducing area occupied by the VDD lines (601), lessening occupation of VDD lines (601) on the area of circuit board, while realizing connection of circuit input terminals (603) of respective sub-pixels and VDD lines (601) by the VDD connecting line (602).

主权项

1. An active matrix organic light-emitting-diode (AMOLED) display backboard, comprising:
a pixel unit array, wherein each pixel unit comprises N sub-pixels and defined by gate lines and data lines; power source signal lines (VDD) in a number less than that of sub-pixels n×N in one row; at least one VDD connecting line intersected or non-coplanarly intersected with the VDD lines; wherein the VDD connecting line is configured to connect circuit input terminals of respective sub-pixels and VDD lines; the VDD lines have a width N times greater than that of the data lines, where M is a positive, integer larger than or equal to 2, and; wherein the VDD connecting line and gate electrode are formed from a same gate layer which forms part of a sub-pixel capacitor.
