Abstract
A system with switch and on-screen display function includes a display device and a switch device. The display device includes a display panel and a display circuit. The display circuit is coupled with the display panel and is configured to control the display device. The display circuit includes an on-screen display generating circuit. The switch device is coupled with the display device and is configured to switch an access to one of at least two computers. The on-screen display generating circuit includes a signal receiving circuit, a processing circuit and a signal outputting circuit. The signal receiving circuit is configured to receive command signals from the switch device. The processing circuit generates first on-screen display menu signals for providing a first on-screen display menu in response to the received command signals. The signal outputting circuit of the on-screen display generating circuit provides the first on-screen display signals to the display panel.
