Switch and on-screen display systems and methods
First Claim
1. A keyboard-video-mouse (KVM) system comprising:
- a display device configured for displaying information, the display device including a display panel and a display circuit, the display circuit being coupled with the display panel and including an on-screen display generating circuit and a display control processor, wherein the on-screen display generating circuit further comprises;
a signal receiving circuit configured to receive command signals from the KVM switch device, the command signals being generated in response to a first command for controlling the KVM switch device;
a processing circuit configured to generate, responsive to the received command signals, first on-screen display signals for providing a first on-screen display menu; and
a signal outputting circuit configured to provide the first on-screen display signals to the display panel; and
a KVM switch device coupled with the display device, the KVM switch device being configured to switch an access to one of at least two computers and having a switch control processor,wherein the display control processor of the display device and the switch control processor of the KVM switch device is able to communicate with each other by exchanging handshake signals, andwherein the on-screen display generating circuit of the display device provides the first on-screen display menu without the need of including an on-screen display generating circuit in the KVM switch.

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.
