Abstract
A liquid crystal display with a force sensitive display surface has a liquid crystal layer between a liquid crystal control layer and a window layer. A color filter layer with color filters or a 3D filter layer with 3D barrier units may be provided between the liquid crystal layer and the window layer. The control, window, color or 3D filter layer comprises an electrically conductive sensor structure comprising piezoresistive material for sensing the force applied by a user's finger on the display, and the sensor structure may, additionally, provide capacitance varying for sensing the touch position.
