Projected Capacitive Touch Panel
Ocular’s Crystal Touch projected capacitive touch panels allow system designers to combine the vibrant optical quality of a TFT display, the robust functionality of a TRUE multi-touch panel and the extreme durability of projected capacitive technology required by demanding embedded applications. Crystal Touch is made of capacitive glass, resulting in a very durable touch panel that is less susceptible to scratching, chemicals in the environment and other contaminants. The all-glass construction of Crystal Touch ensures a crystal clear image.

Consumer demand for products with a clean, zero-bezel, industrial look make Ocular’s Crystal Touch projected capacitive touch panels a perfect fit for touch applications requiring a high tech, leading-edge look. Along with its durability, performance and clarity, Crystal Touch provides significant design flexibility and has been used in many cover lens configurations, including zero-bezel designs. Standard Crystal Touch projected capacitive touch panels are available with Chip on Flex (COF) controller assemblies or the controller is integrated on a Printed Circuit Board (PCB). Standard panels also are available with or without a pre-integrated, optically bonded cover glass.
Standard Crystal Touch panels are available in sizes ranging from 3.5″ to 18.5″ and custom designs start at 2.5″ up to 23″ diagonally. Crystal Touch: TRUE Multi-Touch and Crystal Touch: TRUE Multi-Touch PLUS panels provide a ruggedize touch interface ideally suited for industrial applications and extreme environments. For smaller devices that require a thinner stack-up, the Crystal Touch EDGE single-layer design is now available.
All Crystal Touch panels perform more reliably for a longer period of time than a typical resistive touch panel, which is made of film and depends upon the flexibility of the panel to register a user selection. Unfortunately, the pressure applied with each touch to a resistive touch panel gradually erodes the structural integrity of the film and reduces reliability. A projected capacitive glass panel like Crystal Touch registers the user selection from the capacitive effects produced when a finger or stylus touches the panel, not the deformation of the panel itself. Therefore, a Crystal Touch panel will have a significantly longer service life than many other touch panel technologies.
