Abstract:
The border routing of conductive traces in devices, such as displays, touch sensor panels, and touch screens, to improve border area space usage, thereby reducing device size, and to reduce trace resistance, thereby improving device operation, is disclosed. The conductive traces can form a staggered stair-step configuration in the device border area, in which the average widths of the traces can be different from each other and each trace can have segments with different widths. The conductive traces can be coupled to an active area of the device to transmit signals to and from the active area in accordance with a device operation. The varying widths can help improve the border area space usage, reduce trace resistance, and reduce the differences in resistance between traces.
