A gaming machine includes a processor, a video controller coupled to the processor, a display device coupled to the video controller, and an input device coupled to the processor and receiving an input from a player. The display device includes a rear display panel and a front display panel arranged between the player and the rear display panel, the front display panel including an electrochromic display panel that is spaced apart from the rear display panel in a viewing direction of the player. The video controller causes the display device to alternate between a first state for displaying a first image on the rear display panel and a second state for displaying a second image on the front display panel. In the first state, the video controller displays the first image on the rear display panel and causes the front display panel to be transparent, and in the second state, the video controller displays the second image on the rear display panel and causes the front display panel to be opaque.

A stereoscopic image display device includes a display 11 divided into sections 13 in each of which displayed are small images 12a to 12d each having a plurality of minute images 14, a shutter panel 16 disposed in front of the display 11 and including first mechanical shutters 17, which are arranged side by side in units of the minute image 14 and time-divisionally divide each section 13 per each of the small images 12a to 12d by switching on and off in units of the minute image 14, and an image forming panel 23 including image forming means 24 arranged side by side for forming an image from light rays from each of the small images 12a to 12d passing through the first mechanical shutters 17 when the first mechanical shutters 17 are on.

A head-up display includes a display panel, a parallax barrier, an optical system including a reflector and an optical member, and a controller. The optical system projects a virtual image of an image displayed by the display panel onto a virtual image plane. The controller controls the display panel such that first second images which have a parallax with each other are projected as a three-dimensional image in a field of view of the user, and a convergence angle at which the user views a point on the three-dimensional image is equal to or less than a maximum convergence angle which is greater by 0.43 degrees than a convergence angle for viewing a point on the virtual image plane and is equal to or greater than a minimum convergence angle which is less by 0.43 degrees than the convergence angle for viewing a point on the virtual image plane.

An organic light-emitting diode (OLED) display and method of driving the same are disclosed. In one aspect, the OLED display includes a display panel including a plurality of pixels and a data driver configured to apply a data signal to the display panel in one of two-dimensional (2D) and stereoscopic display modes. The display also includes a controller configured to convert an image signal to 2D image data for the pixels at each of N×k sub-fields in the 2D display mode and convert the image signal to stereoscopic image data for the pixels at each of N sub-fields in the stereoscopic display mode, where N and k are integers greater than 1. The display further includes a frame memory configured to store the 2D image data in the 2D display mode and the stereoscopic image data in the stereoscopic display mode.

The aspect of the embodiments is directed to an image processing apparatus capable of executing gradation processing according to various shapes of boundary portions by determining start positions for starting the gradation processing for applying a gradient to a luminance value in a horizontal direction of an image in positions in a vertical direction of the image.

The invention features techniques and systems for presenting two or more perspective views to each eye of the viewer, through division multiplexing of the viewer's entrance-pupil. The system is constituted by a selective-aperture array with each aperture being transparent only to light beams with some special characteristics, at least one display screen for optical information presentation, and other optional elements. The optical message on at least one display screen propagates to the selective-aperture array directly, or be directed to the selective-aperture array or the eye of the viewer by other optional elements. Through selective filtering by the apertures with temporal filtering characteristics or exclusive filtering characteristics, multiple perspective views get presented to an eye of the viewer through the selective-aperture array. Light rays different perspective views superimpose into real spatial light spots that the eye can focus on naturally, resulting in overcoming of the accommodation-convergence conflict.
