Presented is a system for adjusting an output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels. The system comprises at least one mainboard, at least one LVDS structure, a handshaking mechanism, a LVDS data analyzer and at least one panel. 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 panel via the LVDS structure through a LVDS data analyzer. The LVDS data analyzer is configured to check LVDS output data from the output port according to the panel requirement. The LVDS data analyzer enables or activates or transfers the LVDS output data to the panel, when the panel requirement is matched with the LVDS output data. The system can set the picture of the panel correctly without much time consumption and without a human error.

Description

  • 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.
    • Background of the Invention
  • 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).
  • Hence there are many different driving settings which have to be set for obtaining the corrected picture on the TV of different types that includes but is not limited to 8Bit/10Bit, Jeida/Vesa, Single/Double Clock, Swaped/Not Swapped and so on. So it is quite difficult to try different combinations of settings one by one. This leads to a more time consuming process. Moreover, the picture has to be checked by a person. Hence, detailed errors that occur in the picture may not be noticed by that person and the panel may get driven incorrectly.
  • The prior art does not provide an automatic picture correction for different panels using the same mainboard.
    • Object of the Invention
  • It is therefore the object of the present invention to provide a system, in particular a system for adjusting an output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels, and a method that reduces time consumption and eliminates human error while setting the picture manually compared to the known system and methods.
    • Description of the Invention
  • 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.
  • This solution is beneficial since such a system for adjusting output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels has the ability to set the picture of the panel correctly without much time consumption and without a human error.
  • Further preferred embodiments are subject-matter of dependent claims and/or of the following specification parts.

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 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 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 matched with the LVDS output data.
  • This solution is beneficial since such a system for adjusting output signal of an adaptive mainboard low voltage differential signaling (LVDS) provided for different panels has the ability to set the picture of the panel correctly without much time consumption and a human interaction.
  • 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. However, if a problem is detected by the LVDS data analyzer 8, it directly informs the main processor of the board and changes the data sequence to correct data. The mainboard LVDS block sets the output according to this feedback data and resends the data to the analyzer block. This procedure will continue until correct data are available on the output 9. With this structure the LVDS analyzer detect all the errors which cannot be detected by a human eye.
