Abstract: An LCD monitor includes a front shell, a display device, a back frame, an electrical circuit, and an EMI shield. The front shell provides the appearance and the strength of the LCD monitor. The display device is directly mounted on the back of the front shell. The front shell can protect the display device from damage. The back frame is mounted on the back of the display device for providing the strength of the LCD monitor and protecting the display device from damage. The electrical circuit is positioned on the back of the back frame and electrically connects with the display device for driving the display device. The EMI shield is mounted on the back of the back frame and contacts with the electrical circuit for shielding from an EMI. Furthermore, the EMI shield can improve an EMI shielding effect by directly contacting with the back frame.
