Definitions

  • This invention refers to a system for adjusting an output signal of an adaptive mainboard LVDS (low voltage differential signaling) for different panels according to claim 1 and a method according to claim 5.
  • LVDS low voltage differential signaling
  • Mainboards of electronic monitoring devices are used for driving many different panel sizes and resolutions. Same mainboard can support different panel by setting different driving option for each panel. If the mainboard is connected to drive a new panel, then many different combination of settings need to be checked manually in order to get a correct picture in a display device or TV (8Bit/10Bit, Jeida/Vesa, Single/Double Clock, Swaped/Not Swapped and so on).
  • the prior art does not provide an automatic picture correction for different panels using the same mainboard.
  • LVDS mainboard low voltage differential signaling
  • the before mentioned object is solved by a system for adjusting output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels according to claim 1.
  • the system for adjusting output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels according to the present invention preferably comprises of at least one mainboard, at least one LVDS structure, a handshaking mechanism, a LVDS data analyzer and at least one panel.
  • the LVDS structure includes a plurality of output port and a plurality of input port.
  • the handshaking mechanism is provided in between the panel and the mainboard for selecting LVDS port definition which in turn transfers the panel requirement to the mainboard.
  • the mainboard is connected to the input port of the LVDS structure and the output port of the LVDS structure connected to the panel through a LVDS data analyzer.
  • the LVDS data analyzer is configured for checking LVDS output data from the output port according to the panel requirement.
  • the LVDS data analyzer enables the LVDS output data to the panel, when the panel requirement is matched with the LVDS output data.
  • the handshaking mechanism is configured to allow the panel to inform data for the input port of the LVDS structure to the mainboard.
  • the LVDS data analyzer can inform the mainboard when the panel requirement is mismatched with the LVDS output data.
  • the LVDS structure can set the output according to a feedback data from the panel and resends the data to the LVDS data analyzer, until the panel requirement is matched with the LVDS output data.
  • the before mentioned object is also solved by a method for adjusting output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels according to claim 5.
  • the method of claim 5 preferably comprises the steps: providing a handshaking mechanism in between the panel and the mainboard for selecting LVDS port definition thereby to transfer the panel requirement to the mainboard, connecting the mainboard to the input port of the LVDS structure, connecting the output port of the LVDS structure to the panel through a LVDS data analyzer, configuring a LVDS data analyzer for checking LVDS output data from the output port according to the panel requirement, and enabling the LVDS output data to the panel when the panel requirement matched with the LVDS output data through the LVDS data analyzer.
  • the method for adjusting output signal of an adaptive mainboard LVDS provided for different panels further comprising the steps of, allowing the panel to inform data for the input port of the LVDS structure to the mainboard through the handshake mechanism.
  • the method for adjusting output signal of an adaptive mainboard LVDS provided for different panels further comprising the steps of, allowing the LVDS data analyzer to inform the mainboard when the panel requirement is mismatched with the LVDS output data, allowing the LVDS structure to set the output according to a feedback data from the panel, and resending the data to the LVDS data analyzer, until matching the panel requirement with the LVDS output data.
  • Fig. 1 illustrates a system 100 for adjusting the output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels, according to the present invention.
  • the system for adjusting the output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels according to the present invention preferably comprises of at least one mainboard, at least one LVDS structure, a handshaking mechanism, a LVDS data analyzer and at least one panel.
  • the LVDS structure includes a plurality of output port and a plurality of input port.
  • the handshaking mechanism is provided in between the panel and the mainboard for selecting LVDS port definition which in turn transfer the panel requirement to the mainboard.
  • the mainboard is connected to the input port of the LVDS structure and the output port of the LVDS structure connected to the panel through a LVDS data analyzer.

  • the LVDS data analyzer enables the LVDS output data to the panel, when the panel requirement matched with the LVDS output data.
  • the port definition 1 between the panel and the mainboard is set for selecting the input port of the LVDS structure.
  • the mainboard checks whether the panel sends the necessary data 2 for setting the input port of the LVDS structure. If the panel sends the correct data for setting the LVDS structure 3 (that is condition is true) then the mainboard sets its output according to panel data 5. If the panel sends the incorrect data for setting the LVDS structure 4 (that is condition is false) then the mainboard sets its output according to panel data 5.
  • the LVDS data analyzer checks the LVDS data sequence 6. If there is no problem with the data, this analyzer enables the mainboard LVDS output to the panel 7.
  • the LVDS data analyzer 8 detects all the errors which cannot be detected by a human eye.
