DISPLAY DEVICE AND DISPLAY CONTROL METHOD FOR DISPLAY DEVICE

1 . A display device comprising:

a display panel;

a parallax barrier panel in which a plurality of openings capable of being switched into a light transmitting state and a light shielding state with respect to light of the display panel are arrayed; and

a controller being configured to perform control of bringing a predetermined number of openings adjacent to each other out of the plurality of openings into a first state being one state of the light transmitting state and the light shielding state to form a plurality of first state parts, and bringing remaining openings out of the plurality of openings into a second state being another state of the light transmitting state and the light shielding state, and being configured to control the plurality of first state parts to be movable, wherein

the parallax barrier panel includes a plurality of electrodes corresponding to the plurality of openings,

when a potential of one of the plurality of electrodes is a first potential, one of the plurality of openings corresponding to the one of the plurality of electrodes of the first potential enters the first state,

when a potential of one of the plurality of electrodes is a second potential, one of the plurality of openings corresponding to the one of the plurality of electrodes of the second potential enters the second state, and

the controller changes a potential of all of the plurality of electrodes to any of the first potential, a predetermined potential between the first potential and the second potential, and the second potential, and then moves the plurality of first state parts.

2 . The display device according to claim 1 , wherein

after moving the plurality of first state parts, the controller changes the potential of all of the plurality of electrodes to any of the first potential, the predetermined potential, and the second potential, and further moves the plurality of first state parts after the change.

3 . The display device according to claim 2 , wherein

the controller does not change the potential of all of the plurality of electrodes to any of the first potential, the predetermined potential, and the second potential, until the controller moves the plurality of first state parts a plurality of times.

4 . A display control method for a display device,

the display device including

a display panel, and

a parallax barrier panel in which a plurality of openings capable of being switched into a light transmitting state and a light shielding state with respect to light of the display panel are arrayed,

control of bringing a predetermined number of openings adjacent to each other out of the plurality of openings into a first state being one state of the light transmitting state and the light shielding state to form a plurality of first state parts, and bringing remaining openings out of the plurality of openings into a second state being another state of the light transmitting state and the light shielding state being performed, the plurality of first state parts being controlled to be movable,

the parallax barrier panel including a plurality of electrodes corresponding to the plurality of openings,

when a potential of one of the plurality of electrodes is a first potential, one of the plurality of openings corresponding to the one of the plurality of electrodes of the first potential entering the first state,

when a potential of one of the plurality of electrodes is a second potential, one of the plurality of openings corresponding to the one of the plurality of electrodes of the second potential entering the second state,

the display control method comprising

changing a potential of all of the plurality of electrodes to any of the first potential, a predetermined potential between the first potential and the second potential, and the second potential, and then moving the plurality of first state parts.

5 . The display control method according to claim 4 , further comprising

after moving the plurality of first state parts, changing the potential of all of the plurality of electrodes to any of the first potential, the predetermined potential, and the second potential, and further moving the plurality of first state parts after the change.

6 . The display control method according to claim 5 , further comprising

not changing the potential of all of the plurality of electrodes to any of the first potential, the predetermined potential, and the second potential, until the plurality of first state parts are moved a plurality of times.
