Display device and display method
First Claim
1. A display device comprising:
- a display panel comprising a pixel region and a transmission region;
a light blocking member disposed on a rear surface of the display panel; and
a distance sensing member configured to sense a viewing distance between a viewer and the display device,wherein light transmittance of the light blocking member depends on a comparison result of the viewing distance and a proper viewing distance range, wherein the proper viewing distance range is defined by a first value and a second value, wherein the first value is greater than 0 and is calculated based on a height of the display panel, and wherein the second value is greater than the first value and is calculated based on the height of the display panel,wherein the proper viewing distance range is calculated based on a calculated height (H) of the display panel, andwherein the calculated height (H) of the display panel is calculated according to;

Abstract
A display device is disclosed. The display device may include a display panel, a light blocking member, a distance sensing member, and a controlling member. The display panel may include a pixel region and a transmission region. The light blocking member may be disposed on a rear surface of the display panel and have an adjustable light transmittance. The distance sensing member may sense a viewing distance between a viewer and the display device. The controlling member may calculate a proper viewing distance range, may compare the viewing distance with the proper viewing distance range to generate a comparison result, and may adjust the light transmittance of the light blocking member based on the comparison result.
