Abstract: A retinal scanning image display apparatus includes a light source, a scanning unit that scans a light flux from the light source, a reflective surface that reflects the light flux from the scanning unit, and an ocular unit that guides the light flux from the reflective surface to an eye of an observer. Optical paths of the light flux scanned by the scanning unit intersect at an exit pupil position of the ocular unit, and the image display apparatus causes the scanning unit and the reflective surface to shift so that the optical paths of the scanned light flux toward the same image position are respectively moved in parallel to move the intersecting position of those optical paths. This realizes a small retinal scanning image display apparatus capable of keeping the image position substantially constant even when an observer moves their pupil.

Abstract: An image display device includes a first display panel having a substrate with first scanning lines, first signal lines which intersect the first scanning lines, and first switching elements, a second display panel having another substrate with second scanning lines, second signal lines which intersect the second scanning lines, and second switching elements, and a flexible printed circuit board connecting the first display panel with the second display panel. The image display device drives the first display panel in a line inversion mode when only the first display panel displays images, drives the second display panel in a frame inversion mode when only the second display panel displays images, and drives the first display panel and the second display panel in the line inversion mode when both of the first display panel and second display panel display images.

Abstract: According to one embodiment, a commodity information reading and displaying apparatus includes a housing, a reading window, a display device, and a light blocking sheet. The reading window is provided on one surface of the housing and configured to read predetermined information from a commodity held over the reading window. The display device is provided on a surface opposite to the surface of the housing, on which the reading window is provided, and configured to display information concerning the commodity held over the reading window. The light blocking sheet is attached to the display device and configured to limit an angle of field of a display surface of the display device to a direction deviating from the front of the display surface.

Abstract: An image display device includes a first display device and a second display device, which is constituted of a smaller number of signal lines than that of the first display device. The signal lines of both display devices are driven by a common drive circuit. The display of images is alternatively or simultaneously performed using these two display devices. To achieve a suppression of vertical smear and low power consumption in this type of device, the images are displayed in an N-line (N being an integer of 1 or more) inversion drive mode when the display is performed on only the first display device and when the display is performed on both of the first display device and the second display device, while the images are displayed in a frame inversion drive mode when the display is performed only on the second display device.

Abstract: In a mixed reality display system having a video see-through HMD (head mounted display) and a virtual-space image generation unit, a synthesis processing unit for synthesizing a virtual-space image generated by the virtual-space image generation unit and an image captured by the video see-through HMD is provided on the side of the video see-through HMD, and a part of the captured image is transmitted to the virtual-space image generation unit for detecting a marker, so that a communication amount between the virtual-space image generation unit and the video see-through HMD is reduced.

Abstract: An image display apparatus enabling a wearer to observe an image free from a sense of incongruity is disclosed. This image display apparatus has an image forming unit for forming a first image and a second image mutually having a parallax, a first optical unit for guiding the first image to a first eye, a second optical unit for guiding the second image to a second eye, an interval changing portion for changing an interval between the first optical unit and the second optical unit and a signal output portion for outputting a signal corresponding to the interval to an image generating portion which generates the first and second images.

Abstract: The present invention achieves the suppression of vertical smear and the low power consumption when two display devices which differ in number of signal lines are driven by a common signal line drive circuit. An image display device includes two display devices formed of the first display device PNL1 and the second display device PNL2 which is constituted of signal lines smaller in number than the signal lines of the first display device PNL1. The signal lines which are driven by a common drive circuit DR are used in common by signal lines DLm of the first display device and by signal lines DLs of the second display device. The display of images is alternatively or simultaneously performed using these two display devices PNL1 and PNL2.
