Description

  The present invention relates to a personal computer, and more particularly to a notebook personal computer having a thin-film touch keyboard structure.

  A keyboard is one of the indispensable peripheral devices for a desktop or laptop computer, and has a specific function for executing a command input by a user.

  Currently, a keyboard used in a notebook computer includes a touch pad (controls the movement of a cursor), and function keys, key pads, and hot keys all belong to press-type keys. For example, the key includes a key cap, and when the key cap is pressed, the structure inside the key cap pushes down the support frame and the rubber elastic layer, and the rubber elastic layer pushes down the thin-film type or hard type printed circuit board. A signal is generated and input into the PC host.

  The touch pad (controlling the movement of the cursor) and the function keys, keypads and hot keys of the notebook personal computer are all manufactured separately. Since each is assembled on the notebook computer after manufacturing, the time and process are increased and complicated.

  Since the function keys, keypads, and hot keys of a keyboard on a notebook computer have a mechanical structure design, structural sounds are likely to be generated by pressing when used. Furthermore, the key body is easily broken by receiving external force for a long time due to the structure of the key, and the operation signal cannot be input. In addition, the function keys, keypads, and hot keys of the keyboard on the laptop are mechanically designed, so they have a certain level of altitude. It becomes difficult to do. Because modern electronic products are light, thin and small, they do not match modern products.
