Two-dimensional display device

Abstract

A two-D display is characterized by that its upper and lower base plates have the leading wire regions at both sides and a display region between two leading wire regions. The part of electrode wiresin the display region and the part of leading wires in the leading wire regions are directly connected. The rest of them are connected with each other via the electric conducting material in peripheral frames, so reducing the area of non-display region.

Description

technical field [0001] The present invention relates to a flat display device, in particular to a wiring of the flat display device. Background technique [0002] Generally, the panel layout of passive small-size liquid crystal display devices uses transparent conductive layers (such as indium tin oxide (ITO)) as leads, and metal lead layout is rarely used, because the use of metal leads will increase mass production costs and the manufacturing process. Accuracy needs to be upgraded. However, due to the limitation of the manufacturing process precision, the layout lead width and lead spacing must maintain a certain width to avoid disconnection and reduce the chance of short circuit. Well-known panel wiring such as figure 1 As shown, the upper substrate and the central display area of ​​the lower substrate of the panel are respectively arranged with vertical and horizontal electrode lines, and each horizontal electrode line is connected to a lead, and there is a distance d ...

Problems solved by technology

However, if a very thick transparent conductive layer (or metal conductive layer) is used to improve the difference in resistance value, it will not only increase the mass production cost, but also increase the complexity level of the process precision.
