Abstract

Provided are a display system and a method of outputting an image signal corresponding to a display panel. The display system includes an image processor converting original video data input from a video signal converting unit into converted video data corresponding to a recognized output standard and outputting the converted video data; and a display unit including a memory storing characteristic information and serving to display the converted video data as visual information. Here, the image processor reads out the characteristic information from the memory to recognize the output standard. Accordingly, it is possible to adaptively cope with the case where only the display panel is replaced for the purpose of improvement in resolution, etc.

Dependent claims

A display system comprising:

an interface configured to couple the display system to a plurality of different display units one at a time, each of the plurality of different display units having at least one display characteristic that is different from a corresponding display characteristic of other display units among the plurality of different display units, and the at least one display characteristic including at least one of a resolution, a screen ratio, and a vertical frequency corresponding to the respective display unit of the plurality of different display units;
and
an image processor configured to:
monitor the interface to determine whether one of the plurality of different display units has been replaced based on a reset of a circuit connection of the interface;
determine whether a particular display unit comprises a non-volatile memory that stores the at least one display characteristic, the particular display unit being a display unit from among the plurality of different display units that is coupled to the display system via the interface;
read the at least one display characteristic from the memory of the particular display unit through the interface of the display system if it is determined that the particular display unit comprises the non-volatile memory that stores the at least one display characteristic;
determine an output standard with which a video signal is to be output to the particular display unit based on the at least one display characteristic if the at least one display characteristic is read from the memory of the particular display device;
automatically update the image processor to use the output standard with which the video signal is to be output to the particular display unit;
convert original video data that is received from a video signal converting unit into converted video data corresponding to the output standard if the output standard is determined based on the at least one display characteristic;
and
output the converted video data to the particular display unit if the original video data is converted,
wherein the image processor is configured to read out the at least one display characteristic from the memory of the particular display unit at the time of first coupling the interface to the particular display.
