Abstract
A touchscreen (126) for assembly onto a liquid crystal display module (119) in a wireless communication device (103). The touchscreen is comprised of a front laminant pet film (127), a chemically strengthened glass panel (129), an optically clear acrylic adhesive (131) and a rear laminant pet film (133). The rear laminant pet film (133) greatly increases the strength and durability of the touchscreen (126) and eliminates the need for a protective lens over the display module of the wireless communication device (103).
Claims10
A touchscreen for a liquid crystal display module comprising:
- a front laminant;
- a circuitry layer disposed underneath the front laminant;
- a glass panel disposed underneath the circuitry layer;
