45 results about "Parallax barrier" patented technology

A parallax barrier is a device placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic or multiscopic image without the need for the viewer to wear 3D glasses. Placed in front of the normal LCD, it consists of an opaque layer with a series of precisely spaced slits, allowing each eye to see a different set of pixels, so creating a sense of depth through parallax in an effect similar to what lenticular printing produces for printed products and lenticular lenses for other displays. A disadvantage of the method in its simplest form is that the viewer must be positioned in a well-defined spot to experience the 3D effect. However, recent versions of this technology have addressed this issue by using face-tracking to adjust the relative positions of the pixels and barrier slits according to the location of the user's eyes, allowing the user to experience the 3D from a wide range of positions. Another disadvantage is that the horizontal pixel count viewable by each eye is halved, reducing the overall horizontal resolution of the image.

Dual view display

A computer that includes a processor and a memory, the memory including instructions executable by the processor to provide direct backlighting to a display device by generating a first image at a first viewing angle during a first time period by energizing an LED zone to a first luminance, controlling a first LCD zone to be at a first transparency and controlling a second LCD zone to be non-transparent. A second image can be generated at a second viewing angle during a second time period by energizing the LED zone to a second luminance, controlling the first LCD zone to be non-transparent and controlling the second LCD zone to a second transparency. The first luminance can be transmitted through the first LCD zone disposed over the LED zone and directed at the first viewing angle by a parallax barrier when the first LCD zone is at the first transparency and the second luminance can be transmitted through the second LCD zone disposed over the LED zone and directed at a second viewing angle by the parallax barrier when the second LCD zone is at the second transparency.
