ABSTRACT:
An exemplary key switch system (23) includes a key switch (292), an indicator lamp (29), and a light guide portion (279). The indicator lamp is configured for indicating a working status of the key switch, and emits light beams when the key switch is switched on. The light guide portion is configured for adjusting optical paths of the light beams. Most of the light beams emitted by the indicator lamp are converged by and reflected in the light guide portion and thereupon emit from the key switch system. A flat panel display (200) using the key switch system is also provided.
