Display device and driving method of the same

摘要

In a display device in which a shape of a parallax barrier is changed depending on the relative positional relation to the viewer, the occurrence of crosstalk is suppressed. Images are displayed in a part of a plurality of sub-pixels included in each pixel, and images are not displayed in the other sub-pixels. That is, a display area in the pixel is reduced. Thus, the occurrence of crosstalk can be suppressed. Further, sub-pixels have a square shape or a substantially square shape. Thus, even when sub-pixels which display images are selected depending on the relative positional relation to the viewer, the shape of the display area in the pixel does not change greatly. Therefore, even in the case where the positional relationship is changed (in the case where the arranged parallax barrier is changed), the occurrence of crosstalk can be suppressed without respect to the positional relationship.

1. A driving method of a display device, the display device comprising a display panel comprising a plurality of pixels arranged in matrix, each one of the plurality of pixels comprising A×B sub-pixels arranged in A rows and B columns wherein A and B are natural numbers of 3 or more, the driving method comprising:
emitting light in A sub-pixels arranged in one specific column and not emitting light in A×(B−1) sub-pixels arranged in (B−1) columns other than the one specific column in a first display state; and emitting light in B sub-pixels arranged in one specific row and not emitting light in (A−1)×B sub-pixels arranged in (A−1) rows other than the one specific row in a second display state, wherein the display device further comprises a shutter panel comprising a plurality of optical shutters arranged in a matrix, the driving method further comprising the steps of: arranging a first parallax barrier by bringing a first part of the plurality of optical shutters into a light-shielding state and bringing a second part of the plurality of optical shutters into a light-transmitting state in the first display state; and arranging a second parallax barrier by bringing a third part of the plurality of optical shutters into a light-shielding state and bringing a fourth part of the plurality of optical shutters into a light-transmitting state in the second display state.
