Abstract: A display device includes an image display region displaying images, an automatic light sensor sensing ambient lighting conditions of a location of the display device, and a control system controlling an amount of light produced within the image display region by the displayed images based upon the sensed ambient lighting conditions, wherein the control system includes a single user interface displayed within the image display region and allows simultaneous enabling/disabling of the automatic light sensor and adjusting of image display characteristic values of the displayed images by a user.

Abstract: A liquid crystal display device includes a display panel having an active image display region, a non-image display region surrounding the active image display region, and a border area disposed between the active image display region and the non-image display region, and a backlight device adjacent to the display panel and having a plurality of light producing elements corresponding to the active image display region, wherein the border area is disposed between the active image display region and the non-image display region to diffuse light produced by the light producing elements transmitted through the display panel within the border area.

Abstract: A control system for a portable display device includes a battery power supply powering a display panel of the portable display device, a backlight controller and a video processor connected to the display panel for displaying images, an adaptive controller providing output signals to the backlight controller and the video processor, a video analyzer providing a first input to the adaptive controller, and a remaining display time estimator providing a second input to the adaptive controller, wherein the remaining display time estimator determines a remaining display time of the portable display device and controls the adaptive controller to adjust one of the backlight controller and the video processor based upon the determined remaining display time.

Abstract: 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 illum
