20080316318 | Bit Weighting Alignment in a Display Device - The disclosed embodiments relate to a method and apparatus to align bit weights in a display device. There is provided a method for calibrating light output in a display device, the method comprising: displaying a first video pattern, the first video pattern comprising a first set of pixels divided into a first subset of pixels and a second subset of pixels, the first subset of pixels having a first intensity level, the second subset of pixels having an intensity level corresponding to a fully off state; measuring a first light output value associated with the first video pattern; displaying a second video pattern, the second video pattern comprising a second set of pixels, each of the second set of pixels having a second intensity level corresponding to a fraction of the first intensity level, the fractional value of second intensity level being determined so that a second light output value associated with the second video pattern is intended to equal the first light output; measuring the second light output value; and adjusting the fractional value of the LSB to converge the second light output value with the first light output value. | 12-25-2008 |
20090103006 | Backlight assembly and liquid crystal display device using the same - A liquid crystal display (LCD) device includes an LCD panel having an exterior surface with a first area and an interior surface; a light filter layer having an exterior surface provided at the interior surface of the LCD panel and an interior surface; a light guide assembly provided behind the interior surface of the light filter layer, the light guide assembly including a plurality of light pipes; a light source including a plurality of selectively illuminated lamps arranged at a lateral side of the light guide assembly, each of the lamps being respectively associated with a different one of the light pipes for emitting light into the respective light pipe; a plurality of diffusion surfaces, each of the diffusion surfaces being provided on a selected area of a respective one of the plurality of the light pipes, the selected area being smaller than the first area; wherein each of the diffusion surfaces causes light to be emitted from the selected area of the respective light pipe when the light pipe is illuminated by the lamp associated therewith. | 04-23-2009 |
20100208043 | METHOD AND SYSTEM FOR CREATING A 3D EFFECT ON A DISPLAY DEVICE - A method of operating a digital video device to create an effect of a three-dimensional image comprises loading a left image into a frame buffer prior to displaying the left image on a display of the digital video device. The method additionally comprises writing a right image, displaying the right image to a right eye of a viewer, powering on a backlight to allow the right eye of the viewer to view the right image, powering off the backlight, loading a subsequent right image into the frame buffer prior to displaying the subsequent right image, writing the left image to the display, displaying the left image to a left eye of the viewer, powering on the backlight to allow the left eye of the viewer to view the left image and powering off the backlight. | 08-19-2010 |
20100231610 | SYSTEM AND METHOD FOR IMPROVING BATTERY LIFE IN AN ELECTRONIC DEVICE - A method of conserving battery life in an electronic device comprises receiving a low power user image size preference. The method additionally comprises adjusting an image size responsive to a user request to invoke the low power user image size preference so that an adjusted image displayed by the electronic device occupies an image zone that is smaller than an entire display size of the electronic device, and illuminating only areas within the image zone. | 09-16-2010 |
