Problems solved by technology

However, when an open circuit is created in one of the supply lines 23, a whole row of pixels cannot work, thus forming a stripe pattern on the screen
In addition, if an open circuit occurs between the power supply line 23 and the data line 13, the entire row of pixels cannot work.

Abstract

An active-matrix organic light-emitting device, comprising a plurality of gate lines and data lines arranged laterally and vertically, which define a plurality of pixel areas, and a plurality of power lines arranged substantially in parallel with the data lines, arranged in a At least one switching thin film transistor inside the pixel area, at least one driving thin film transistor inside a pixel area, and an organic light-emitting unit formed inside a pixel area, when the driving thin film transistor is enabled, a signal is provided through a power line It is illuminated, and a plurality of power lines having at least two layers electrically interconnected, the power lines being electrically connected to the plurality of power lines to provide signals to the respective power lines.

Description

technical field [0001] The invention relates to an active matrix organic light emitting device, in particular to an active matrix organic light emitting device and a manufacturing method thereof, which can provide a power supply for a redundant power supply line even if an open circuit occurs on the power supply line. Background technique [0002] Conductive organic materials such as conjugated polymer poly(p-phenylinevinyline) (PPV) are currently being investigated for applications in light-emitting devices. In addition, research on conductive organic materials for applications in thin-film transistors (TFTs), sensors, lasers, and optoelectronic devices is ongoing. The current light-emitting devices made of inorganic phosphorus materials have disadvantages because the operating voltage of the devices must be above 200VAC. This makes it difficult to scale up the overall size of the devices because they are fabricated using a vapor process. It is thus difficult to obtain bl...
