Abstract
Techniques are described to transmit commands to a display device during vertical or horizontal blanking intervals. The commands can be transmitted using fields that would otherwise be used to transmit color information. A Low Voltage Differential Signaling (LVDS) compliant interface can be used to transmit the commands.
Claims19
A method comprising:
- outside of a vertical or horizontal blanking interval, receiving color data in fields allocated for color data;
- during one of a vertical or horizontal blanking interval, receiving information related to a command in the fields allocated for color data, wherein at least one color data field received during a blanking interval is also received outside of the blanking interval;
- receiving a data enable (DE) signal and Hsync and Vsync signals, the received DE signal to indicate whether a combination of the fields allocated for color data and the Hsync and Vsync signals convey a command, wherein when the DE signal indicates the fields allocated for color data and the Hsync and Vsync signals convey a command, the command is specified using values in each of the fields allocated for the color data, Hsync, and Vsync signals;
- and
- requesting to perform the command.

A method comprising:
- during one of a vertical or horizontal blanking interval, causing transmission of information related to a command using fields allocated for color data;
- outside of a vertical or horizontal blanking interval, causing transmission of color data in the fields allocated for color data, at least one color data field transmitted during a blanking interval is also transmitted outside the blanking interval;
- transmitting a data enable (DE) signal;
- and
- transmitting Hsync and Vsync signals, the DE signal to indicate whether a combination of the fields allocated for color data and the Hsync and Vsync signals convey a command, wherein when the DE signal indicates the fields allocated for color data and the Hsync and Vsync signals convey a command, the command is specified using values in each of the fields allocated for the color data, Hsync, and Vsync signals.

A system comprising:
- at least one antenna;
- a display device;
- a frame buffer;
- a host system communicatively coupled to the at least one antenna and the frame buffer;
- and
- an interface to communicatively couple the display device and the host system, the host system comprising:
- logic to form a communication for transmission to the display device using the interface, wherein:
- during one of a vertical or horizontal blanking interval, the communication is to include information related to a command using fields allocated for color data;
- outside of a vertical or horizontal blanking interval, the communication is to include color data in the fields allocated for color data, at least one color data field transmitted during a blanking interval is also transmitted outside the blanking interval;
- and
- the communication is to include a data enable (DE) signal and Hsync and Vsync signals, the DE signal to indicate whether a combination of the fields allocated for color data and the Hsync and Vsync signals convey a command, wherein when the DE signal indicates the fields allocated for color data and the Hsync and Vsync signals convey a command, the command is specified using values in each of the fields allocated for the color data, Hsync, and Vsync signals.
