Display device

A display device comprising:

• a display panel including a display region simultaneously displaying a first screen and a second screen;
• a detection sensor including a detection region overlapping the display region;
• and
• a control circuit having a first detection function to detect a physical object that is in proximity to the display panel and a second detection function to detect a touch on a graphical object displayed on an operation target screen that is one of the first screen and the second screen,
• wherein
• the first screen is recognized from a viewpoint on the right relative to the display region,
• the second screen is recognized from a viewpoint on the left relative to the display region,
• in the first detection function, the control circuit generates, based on detected values of a plurality of regions acquired by dividing the detection region into the regions, a heat map weighted with the detected values of the regions and determines the operation target screen based on the heat map,
• the control circuit determines the operation target screen based on a tilt at the barycenter position of the heat map, and
• the control circuit:
• calculates the tilt at the barycenter position of the heat map by assuming that a first direction is a direction extending in a right-left direction relative to
• the display region, a second direction is a direction orthogonal to the first direction, a direction from bottom to top in the second direction corresponds to 0 degrees, and a direction tilted to the left corresponds to a positive value;
• determines the first screen to be the operation target screen when the tilt at the barycenter position of the heat map is equal to or larger than 0 degrees;
• and
• determines the second screen to be the operation target screen when the tilt at the barycenter position of the heat map is smaller than 0 degrees.

• and
• executes matching processing between a heat map acquired in the detection period and the second heat map and determines the second screen to be the operation target screen when a match between the maps is determined.
