Organic Light Emitting Diode Display with Narrow Bezel

Abstract

An organic light emitting diode display with a narrow frame comprises a substrate having an effective display area and a routing area, a plurality of first axial electrodes and a plurality of second axial electrodes corresponding to the effective display area of ​​the substrate , a plurality of organic luminescent bodies, a layer of insulating layer, a plurality of bridging wires, and a plurality of first scanning wires and a plurality of second scanning wires located in the wiring area of ​​the substrate. In the present invention, each bridging wire is only routed through the lower side of the effective display area to extend to the routing area and is used to connect the respective first axial electrodes and the respective first scan wires, and each second scan wire The wires are routed on the lower side of the effective display area and connected to the respective second axial electrodes to improve the left and right sides of the existing display viewing surface. A certain width of the routing area still needs to be reserved and the routing cannot be reduced. The disadvantage of area, so it can indeed further achieve the purpose of reducing the width of the frame.

Description

technical field [0001] The present invention relates to a display, in particular to an organic light emitting diode display with a narrow frame. Background technique [0002] In the existing passive matrix OLED (Passive Matrix OLED, PMOLED for short), a plurality of anode scan signal lines (Segment scanline) and a plurality of cathode scan signal lines (Common scanline) are respectively along a first horizontal direction orthogonal to each other and a The second horizontal direction extends to the outside of an active display area, and is electrically connected to the driving IC through a plurality of contact nodes and a plurality of scanning signal lines located on the left and right sides of the active display area. In recent years, as the mainstream of display design is developing towards narrow border (Narrow Border), the existing methods to achieve narrow border by "reducing the line width of the wires" and "reducing the distance between two wires" have the following di...

AI Technical Summary

Problems solved by technology

[0003] 1. Excessively reducing the line width of the wire will not only increase the resistance value of the wire itself, but also lead to the problem of a decrease in the process yield

[0004] 2. Excessively reducing the distance between two wires will increase the risk of short circuit between two adjacent wires

[0005] Therefore, just have another kind of wiring technology that vertically stacks by conducting wire to be proposed, as the disclosed a kind of display of Chinese Taiwan's new patent No. To the left and right sides adjacent to the effective display area, that is to say, the two sides of the substrate of the patent still have a certain width of the wiring area, and it is impossible to further reduce the outer frame of the substrate and the effective display area. The distance between the two makes the narrow frame development technology face another bottleneck
