Abstract

Provided is a display system. The display system includes: a display; a sensor that senses light that is irradiated onto the surface of the display; and a controller that locally adjusts the luminance of a partial area in which visibility deteriorates as a result of the irradiated light in all display areas of the display.

First claim

What is claimed is:

1 . A display system comprising:
a display device configured to display at least one content; a sensor configured to sense light that is irradiated onto a surface of the display device; and a controller configured to locally adjust a luminance of at least one portion of the display device at which the sensed light causes a deterioration in a visibility of the displayed at least one content.

2 . The display system as claimed in claim 1 , wherein:
the display device includes a plurality of displays that are combined with each other in order to display a single content, and the controller is further configured to increase the luminance of at least one portion of the plurality of displays to which the sensed light is irradiated.

3 . The display system as claimed in claim 2 , wherein the sensor includes a plurality of illuminance sensors that are distributed in at least one from among a plurality of connectors and a plurality of bezel areas that are included in the plurality of displays.

4 . The display system as claimed in claim 3 , wherein when illuminance values of light sensed by the plurality of illuminance sensors are nonuniform, the controller is further configured to generate a light intensity map by interpolating the illuminance values and to use the light intensity map for the adjusting the luminance.

5 . The display system as claimed in claim 1 , wherein the controller is further configured to determine a first area in which an illuminance of the sensed light is greater than a first threshold as an invisible area, to determine a second area in which the illuminance of the sensed light is greater than a second threshold and equal to or less than the first threshold as a visibility deterioration area, and to determine a third area in which the illuminance of the sensed light sensed is less than the second threshold as a normal area in order to perform different respective processing functions with respect to each of the first area, the second area, and the third area.

6 . The display system as claimed in claim 1 , wherein:
the display device includes a plurality of displays that are combined with each other in order to display a single content, and when at least one invisible area exists in the display device, the controller is further configured to modify at least one from among a layout and a scale of the single content so that the single content is not displayed in the at least one invisible area.

7 . The display system as claimed in claim 1 , wherein:
the display device includes a plurality of displays that are combined with each other in order to display a single content, and when at least one invisible area exists in the display device, the controller is further configured to modify a layout of the single content so that a primary object from among a plurality of objects included in the single content and displayed in the at least one invisible area is moved to an area that is outside of the at least one invisible area to be displayed.

8 . The display system as claimed in claim 1 , wherein:
the display device includes a display panel, and the sensor includes a light quantity sensing layer disposed in a rear direction of the display panel.

9 . The display system as claimed in claim 8 , wherein the controller is further configured to correct a content color of an area of the display device in which the sensed light is incident in order to offset a color change influence by the incident light.

10 . The display system as claimed in claim 1 , wherein:
the display device includes a single display panel configured to display a single content, and when the visibility of the displayed single content deteriorates, the controller is further configured to locally increase the luminance of the at least one portion of the display device.

11 . A method for enhancing visibility in a display system, the method comprising:
displaying a plurality of contents by using a display device that includes a plurality of displays that are combined with each other in order to display the plurality of contents as a single content; sensing light that is irradiated onto a surface of the display device; and locally adjusting a luminance of at least one portion of the display device at which the sensed light causes a deterioration in a visibility of the displayed single content.

12 . The method as claimed in claim 11 , wherein the sensing the light comprises sensing an illuminance of the irradiated light by using a plurality of illuminance sensors that are distributed in at least one from among a plurality of connectors and a plurality of bezel areas that are included in the plurality of displays.

13 . The method as claimed in claim 12 , wherein the locally adjusting the luminance includes:
generating, when illuminance values of light sensed by the plurality of illuminance sensors are nonuniform, a light intensity map by interpolating the illuminance values, determining the at least one portion of the display device at which the visibility deteriorates by using the light intensity map, and increasing the luminance of the determined at least one portion of the display device.

14 . The method as claimed in claim 12 , the method further comprising:
determining a first area in which the illuminance of the sensed light is greater than a first threshold as an invisible area, determining a second area in which the illuminance of the sensed light is greater than a second threshold and equal to or less than the first threshold as a visibility deterioration area, and determining a third area in which the illuminance of the sensed light is less than the second threshold as a normal area.

15 . The method as claimed in claim 14 , the method further comprising:
modifying, when at least one invisible area exists in the display device, at least one from among a layout and a scale of the plurality of contents so that the plurality of contents are not displayed in the at least one invisible area.

16 . A display system comprising:
a first display screen; a first sensor configured to sense light that is incident upon the first display screen; and a controller configured to control the first display screen such that an image is displayed on the first display screen, to determine an adjustment for improving a visibility of the image based on the sensed light, and to perform at least one image processing function so as to implement the determined adjustment to the displayed image.

17 . The display system of claim 16 , wherein the at least one image processing function includes at least one from among increasing a luminance of at least one pixel, modifying a color of at least one pixel, modifying a layout of the image, and modifying a scale of the image.

18 . The display system of claim 16 , wherein the controller is further configured to determine a first area of the first display screen in which an illuminance of the sensed light is greater than a first threshold as an invisible area, to determine a second area of the first display screen in which the illuminance of the sensed light is greater than a second threshold and equal to or less than the first threshold as a visibility deterioration area, and to determine a third area of the first display screen in which the illuminance of the sensed light sensed is less than the second threshold as a normal area in order to perform different respective image processing functions with respect to each of the first area, the second area, and the third area.
