To provide a naked-eye type stereoscopic display device which can achieve a fine stereoscopic display property while achieving high-definition display and high yield. An aperture part includes overlapping regions which overlap with an aperture part or another aperture part neighboring to each other in a second direction and a non-overlapping region which does not overlap. Provided that a light amount emitted from a linear aperture of the aperture part in parallel to a second direction is 'longitudinal light amount', the non-overlapping region includes longitudinal light amount fluctuating regions where the longitudinal light amount changes continuously from roughly a center of the aperture part towards both ends of the first direction, respectively. The sum of the longitudinal light amounts of the two overlapping regions overlapping with each other at a same position in the first direction is larger than the longitudinal light amount in roughly the center of the aperture part.

Stereoscopic display device

An electronic device having a display screen that displays a user interface including at least one object, comprising: a display mechanism that displays the user interface; a coordinate detection mechanism that detects coordinates of a user touch point on the display screen; a first feedback presentation mechanism that presents tactile feedback at a prescribed point to make the user perceive the presence of an object; a measurement mechanism that measures a force generated by the user pressing the display screen; and a second feedback presentation mechanism that detects an operation trigger based on the force and generates mechanical vibration.

To provide a naked-eye type stereoscopic display device which can achieve a fine stereoscopic display property while achieving high-definition display and high yield. Aperture parts of sub-pixels neighboring to a first direction include overlapping regions which overlap in a second direction and a non-overlapping region which does not overlap. Provided that a width of the aperture part in the second direction is defined as a longitudinal aperture width, the non-overlapping region includes an aperture width fluctuating region where the longitudinal aperture width changes continuously from roughly a center of the aperture part towards both ends of the first direction, respectively. The sum of the longitudinal aperture widths of the two overlapping regions overlapping with each other at a same position in the first direction is larger than the longitudinal aperture width in roughly the center of the aperture part.

Electronic device and control method with feedback to perceive presence and activation of an object

A tactile presentation device includes a panel having a tactile presentation region including a plurality of electrodes, and a controller configured to control the panel. The controller is configured to supply a first sinusoidal signal and a second sinusoidal signal simultaneously to a first region in the tactile presentation region. The first sinusoidal signal and the second sinusoidal signal are supplied to different electrodes in the first region. The first sinusoidal signal and the second sinusoidal signal have the same frequency and different phases. The controller is configured to supply a reference signal having an amplitude smaller than the first sinusoidal signal and the second sinusoidal signal to a peripheral region surrounding the first region.

Tactile presentation device and electronic equipment

A stereoscopic image display device includes: a display panel on which pixels each constituted with a plurality of sub-pixels formed with electro-optic elements by corresponding to parallax images are arranged in matrix; and an optical module which distributes light emitted from the pixels arranged in the first and second directions to different directions from each other along the first and second directions, respectively. The display panel includes first and second non-control regions which are the regions existing between boundaries of apertures of the sub-pixels where control of electric-optic conversion cannot be done. An intersection part of the first and second non-control regions is disposed on a lattice point that is an intersection point of segments in a unit lattice constituted with lattice lines, and the first or the second non-control region is bent at least once within the unit lattice with respect to the lattice lines.
