Abstract: An exemplary flat panel display includes a seat, a connection member, and a display module. The seat includes a supporting member having a first engaging portion at a top end thereof, and the first engaging portion includes two pins and two fixing holes. The connection member includes two fixing components. The display module is mounted on the supporting member, and includes a second engaging portion having two positioning slots. The pins of the first engaging portion are received in the second engaging portion, the fixing components are fixed in the fixing holes via the positioning slots, and the positioning slots provide paths for the fixing components when the display module is rotated about the pins.

Abstract: An exemplary liquid crystal display device (20) includes a rear frame (25) including a plurality of first through holes (251) and a shield (24) including a back frame (241). The back frame includes a plurality of second through holes (244) corresponding to the first through holes, respectively. The back frame further includes a plurality of fixing units (245), and the shield further includes a plurality of shielding units (240) corresponding to the fixing units respectively. Each of the shielding units is fixed to a corresponding one of the fixing units by insert directly into the fixing unit.

Abstract: A liquid crystal display device includes a liquid crystal display module, a circuit board, and a shield case. The circuit board is mounted on the liquid crystal display module and has a socket for receiving a power supply plug. The shield case includes an offset portion on a rear part to contain the circuit board. An opening formed with holding members for securing the socket is provided at the offset portion.

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.
