Touch Lens
Traditional touch screens are laminated to the display panel and is installed underneath the bezel cover of a device, which produce a depressed appearance of the display panel. To achieve a fully flat touch interface, touch lens technology integrates the display lens with the face cover to create a seamless look and feel.
Touch lens is essentially a redesign of the traditional resistive touch screen technology. a perfect combination of the 4 wire design and lens integration (PET film with printing).
As more and more devices are designed to feature increasingly flat touch modules, a diverse range of applications are also emerging to compliment this technology, thus making touch lens design a popular choice
