1. An apparatus for data input into an electronic device, comprising:
- a plurality keypanels and a fold line in between two adjacent keypanels, along the fold lines, the keypanels can be folded, wherein the keypanels form a substantially smooth surface when unfolded, wherein the surface is divided into a plurality of keyareas and a unique keystroke signal can be generated by the keyarea when the keyarea is pressed; and
a connector through which the signals from keypanels are transmitted to the electronic device.

Abstract
A novel keyless keyboard uses membrane switches or touch screen to generate keystroke signals, without traditional keycaps. The keyless keyboard can be folded to further reduce its size during storage. The keyless keyboard unfolds into a keyboard of normal desktop keyboard size for easy use. When touch screen is used, the keyboard is also a display screen.

16. A foldable keyboard for portable electronic devices comprising:
-
a keyboard body having a plurality of touch panels, and a plurality of flexible printed circuits electrically connected two adjacent touch panels in a lateral direction thereby enabling the keyboard body to fold laterally in a stacked way, in which the keyboard body has the same area as that of main typing region on a standard-sized computer keyboard when unfolding the touch panels;
each touch panel having a pair of conductive membranes being segmented into a plurality of blocks, in which the touch panels generates a panel signal when the pair of conductive membranes are pressed into contact, and each block corresponds to a panel signal; and
a plurality of legends formed on the touch panels, wherein the legends respectively corresponds to the blocks and are arranged as the standard keyboard.
