Abstract
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).
Claims17
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, and;
- at least one VDD connecting line intersected or non-coplanarly intersected with the VDD lines;
- wherein the VDD connecting line other than the gate lines is configured to connect circuit input terminals of respective sub-pixels and VDD lines;
- and
- the VDD connecting line and the gate electrode are formed from a same gate layer which forms part of a subpixel capacitor.
A manufacturing method of an active matrix organic light-emitting-diode (AMOLED) display backboard comprises:
- forming a gate layer on a substrate, forming a gate layer pattern including the gate electrode and a connecting line of the power source signal (VDD) lines by a pattern process;
- forming an active layer on the gate layer;
- and
- forming a source-drain layer on the active layer, forming gate lines, data lines, the VDD lines, connecting lines of sub-pixel electrodes, and via holes over the source-drain layer;
- wherein the gate lines and data lines are intersected with each other to define pixel units including sub-pixels, the VDD connecting line other than the gate lines is connected with respective VDD lines, and connecting lines of the sub-pixel electrodes through the via holes, respectively.
