<p>A key structure with multiple appearance effects simultaneously presented at different angles of view, includes: a multi-mode appearance layer, an elastic structure layer and a keypad structure layer. Herein the surface of the multi-mode appearance layer has a plurality of micro-structures which reflect the incident light sources of different wavelengths to different angles. The elastic structure is placed under the multi-mode appearance layer. The keypad structure layer is placed on the multi-mode appearance layer. Thereby, through the micro-structures reflecting the incident light sources of different wavelengths to different angles, a user can see different appearance effects of different patterns at different angles of view. Therefore, the present invention can be applied to the keypad structure of holography, so as to achieve the effect of multi-mode appearance presentation.</p> |
