Abstract
A membrane touch keyboard structure for notebook computers comprises a panel, a sensing layer, a backlight layer and a base layer. The panel includes hot key patterns, a key group pattern, a cursor control pattern, and a sensing key pattern. A first sensing block, first electrode blocks, a second sensing block, a third electrode block or a third sensing block, and a fourth sensing block correspond to sensing layers of the hot key patterns, key group pattern, cursor control pattern, and sensing key pattern. The sensing layers are resistive/capacitive films. The membrane touch keyboard and the touch panel are integrated to reduce the thickness of the notebook computer. When any hot key pattern, key group pattern, cursor control pattern or sensing key pattern is touched, the touch is sensed by the sensing layer to generate and output a sensing control signal to the notebook computer for an operation.
