20080316198 | Display Device, Viewing Angel Control Device, and Electronic Apparatus - A portable phone has a main LCD and a SW-LCD, provided on a path of light to be transmitted by the main LCD, which electrically switches between (i) an image to be seen in a single image display mode and (ii) an image to be seen in a multiple image display mode. Furthermore, a first polarization plate serving as a reflective polarization plate is provided between the SW-LCD and the main LCD, and a second polarization plate is provided on a front surface side of the SW-LCD. The SW-LCD has a liquid crystal layer to which a voltage is applied in the multiple image display mode. With this, an image displayed by an image display can be seen from a front direction. In addition, the image displayed by the image display is blocked by the second polarization plate when the image is seen from the an oblique direction, and outside light from the oblique direction is reflected by the first polarization plate, so that a mirror surface display is carried out. | 12-25-2008 |
20080316366 | Display Device, Viewing Angle Control Device, and Electronic Apparatus - A portable phone has a main LCD and a SW-LCD, provided on a path of light to be transmitted by the main LCD, which electrically switches between (i) an image to be seen in a single image display mode and (ii) an image to be seen in a multiple image display mode. In the multiple image display mode, the display switch makes it possible that (a) the image displayed by the image display is seen from a front direction and (b) an image obtained by superimposing, onto the image displayed by the image display, a switching image formed by the display switch is seen from an oblique direction. The switching image is formed by providing, with at least one of a pair of transparent electrode films for applying a voltage to a liquid crystal layer, a patterning having an area larger than 50% of an area of a display screen. | 12-25-2008 |
20090015732 | DISPLAY APPARATUS - On the display surface side of a DV display apparatus which performs image separation via a parallax barrier, a normally-white TN liquid crystal section is arranged such that a viewing angle direction heads toward the passenger seat. In a case where display is performed for both the driver's seat and the passenger seat, a drive voltage of the TN liquid crystal section is switched off. In a case where display for the driver's seat is set to non-display and an image is displayed only for the passenger seat, a halftone voltage is applied as the drive voltage of the TN liquid crystal section. In the case where display for at least one display direction is set to non-display in a display apparatus which can display different images in plural display directions by using a common display screen, it is possible to prevent image light for other directions from leaking to the non-display direction. | 01-15-2009 |
20090279005 | DISPLAY APPARATUS - In a parallax barrier DV (Dual View) display apparatus, a TN (Twisted Nematic) liquid crystal display panel is adopted as a display device for display images. The TN liquid crystal display panel includes a pair of opposing substrates, a liquid crystal layer sandwiched therebetween, orientation films arranged to orient liquid crystal molecules constituting the liquid crystal layer, and electrodes arranged to independently apply electric fields to areas of the liquid crystal layer which correspond to respective pixels. The orientation films are oriented in such a manner that liquid crystal molecules in the aforesaid areas are oriented so that display directions of the pixels are parallel or substantially parallel to a viewing angle direction. This arrangement improves image separation capability in all display directions, in a DV (Dual View) display apparatus displaying different images in respective display directions, by a single display screen. | 11-12-2009 |

20100091226 | AUTOMATED TELLER MACHINE - An ATM of the present invention includes a liquid crystal display panel having, between two transparent substrates, (i) an image forming layer including at least a liquid crystal layer and a pixel section in which RGB pixels are arranged in a matrix manner, and (ii) a plurality of barriers ( | 04-15-2010 |
20100149136 | DISPLAY DEVICE - In a display device, when a first image is an absolute white image, a direction in which a luminance is maximum is regarded as a main viewing direction for the first image. A luminance Ld in the main viewing direction for the first image in cases where the first image is an absolute black image and other image is an absolute white image, and a luminance Lb in the main viewing direction for the first image in cases where the first image and the other image are absolute black images satisfy a relationship represented by Formula (1): | 06-17-2010 |
