Abstract
A metal keypad panel structure with a micropore array includes a metal keypad panel, a filling, a pattern layer, a backlight module and an electric signal module. The metal keypad panel has micropores filled with the filling. The pattern layer is on a side of the metal keypad panel. The backlight module is a guide light plate attached onto another side of the metal keypad panel and has patterns, each composed of light guide microstructures. When a light is entered into the guide light plate, the light guide microstructures focus and project the light onto the metal keypad panel to allow users to see the position of each press key clearly.
