Problems solved by technology

Each sheet of glass adds thickness and requires expensive glass-to-glass bonding solutions to attach to adjacent substrates
For reflective displays, these issues can be further exacerbated when integrated headlights are also required, increasing module thickness and cost

Abstract

This disclosure provides systems, methods and apparatus for a projected capacitive touch (PCT) sensor that may include thin sensor electrodes coated with additional layers to form an optical cavity that reinforces a wavelength range or color of incident light. The sensor electrodes (907a, 907b) and a cover glass border and / or decorations (1305) may be fabricated simultaneously. In some implementations, the thickness of the optical cavity will be selected such that the "color" of reflected light is black. The sensor electrodes (907a, 907b) may not be noticeable to a human observer. However, in some other implementations, the thickness of the optical cavity may be selected such that the sensor electrodes (907a, 907b) and / or the decorative portions (1305) will have another color. Routing wires (1120a) of the touch sensor may be shielded by a grounded conductive layer in the border.

Description

[0001] Cross References to Related Applications [0002] This application claims the 61st / U.S. Provisional Patent Application No. 480,970 and filed November 4, 2011, entitled "WIRING AND PERIPHERY FOR INTEGRATED CAPACITIVE TOUCH DEVICES" (Attorney Docket No. QUALP050 / 101798) Priority to US Patent Application No. 13 / 290,001, both of which are incorporated herein by reference for all purposes. technical field [0003] The present invention relates to display devices, including but not limited to, display devices incorporating touch screens. Background technique [0004] Electromechanical systems (EMS) include devices having electrical and mechanical elements, actuators, transducers, sensors, optical components (including, mirrors), and electronics.
