Abstract
A touch key control and icon display apparatus includes a first substrate, a light-emitting element, a second substrate, and a body portion. The light-emitting element is disposed adjacent to the first substrate. The second substrate includes a circuit layer configured to sense a touch. The body portion is disposed between the first and second substrates and includes a reflective surface that defines a chamber. The chamber is formed through the body portion and configured to receive the light-emitting element. The circuit layer includes an icon disposed adjacent to an opening of the chamber. A portion of light, from the light-emitting element, incident on the circuit layer can pass through the circuit layer, and another portion of the light can be reflected by the circuit layer.
