  • Display device
    Patent number: 9338444
    Abstract: The occurrence of crosstalk in a display device which performs 3D display is suppressed. When 3D display is performed, part of a plurality of pixels perform desired color display and the other part of the plurality of pixels perform black display. Thus, as compared to the case where all of a plurality of pixels perform desired color display, the occurrence of crosstalk can be suppressed. A plurality of pixels which perform desired color display are changed depending on the display state. Therefore, as compared to the case where a plurality of pixels which perform desired color display are fixed when 3D display is performed, the display device can have a longer period until display change in a pixel becomes obvious (a longer lifetime) and variations in display among the plurality of pixels can be reduced.

  • Projection display intensity equalization
    Patent number: 9304379
    Abstract: In some examples, the intensity of an image projected onto a surface at an oblique angle may be controlled to equalize the intensity, and thereby to eliminate from the image perceptible variations in brightness. For instance, a first distance to a closer portion of the image and a second distance to a farther portion of the image may be used to determine an amount of change to be made to the intensity of at least one portion of the image. In some implementations, a filter may be used to control changes to the intensity of the image. In other implementations, the image information may be modified, such as on a pixel level, to control the intensity of the image.

  • Touch alphabet and communication system
    Patent number: 9280229
    Abstract: A touch alphabet and communication system is provided. The communication system uses a predetermined set of touch gestures, such as fingertip touch patterns performable on keyless touch-sensitive surfaces, to express the user's desired communication. The touch-sensitive surface may be the touch screen display of a computer, tablet device, cell phone, or a touch-sensitive pad, for example. The finger touch patterns are based on a limited set of unique and ergonomically pleasing finger positions that may be performed in a limited area. The touch alphabet allows the user to comprehensively communicate without looking at the communication device, and with just one hand, or in another implementation, with two hands. Thus, a user can comfortably tap an entire alphabet and related functions, with one hand, without having to visualize the user interface surface or hunt for individual keys.
