DISPLAY DEVICE AND DISPLAY SYSTEM

摘要

A display device and display system. Each pixel cell group of the display comprises at least one first line of pixel cells for displaying information to be viewed by a dedicated spectacle wearer, a second line of pixel cells for displaying compensation information, and a third line of pixel cells for displaying naked-eye pattern information. The light adjustment mechanism allows for a difference between the phase retardations experienced by the light emitted by the first line of pixel cells and by the third line of pixel cells upon passing through the light adjustment mechanism. With the display device, the viewer wearing dedicated spectacles and the naked-eye viewer are allowed to see different information, thereby improving the confidentiality of the display device in peep preventive displaying.

1. A display device characterized in that it comprising: a display panel and a light adjustment mechanism, the display panel comprising a plurality of pixel cells distributed in an array, the plurality of pixel cells comprising a plurality of pixel cell groups arranged in a given direction, wherein:
each of the pixel cell groups comprises multiple lines of pixel cells arranged in the direction in which the plurality of pixel cell groups are arranged, wherein the multiple lines of pixel cells comprises: at least one first line of pixel cells for displaying information to be viewed by a dedicated spectacle wearer; a second line of pixel cells for displaying compensation information, wherein along a direction perpendicular to the direction in which the plurality of pixel cell groups are arranged, sub-pixel cells in each said first line of pixel cells and corresponding ones in the second line of pixel cells are of same colors, and a sum of brightness of display information of sub-pixel cells in each said first line of pixel cells and corresponding ones in the second line of pixel cells is a fixed value when in operation; and a third line of pixel cells for displaying pattern information to be viewed by a naked eye; and the light adjustment mechanism is located at a light exit side of the display panel, and makes light emitted out of the display panel by the first line of pixel cells, the second line of pixel cells, and the third line of pixel cells experiences respective phase retardations upon passing through the light adjustment mechanism, wherein: a difference between the phase retardation experienced by the light emitted by each said first line of pixel cells upon passing through the light adjustment mechanism and the phase retardation experienced by the light emitted by the third line of pixel cells upon passing through the light adjustment mechanism is (2a+1)λ/2; and a difference between the phase retardation experienced by the light emitted by each said first line of pixel cells upon passing through the light adjustment mechanism and the phase retardation experienced by the light emitted by the second line of pixel cells upon passing through the light adjustment mechanism is (2a+1)λ/2, wherein a is an integer.
