Display backlight illumination of a housing perimeter
An information handling system display manages direction of illumination from an internal backlight to illuminate the display perimeter. A translucent material disposed between a liquid crystal display panel and backlight manages a color of backlight illumination applied at the display perimeter. In various alternative embodiments, the translucent material selectively adjusts light transmission characteristics to adjust light that passes to a frontside of the liquid crystal display panel.

The self-luminous element of the first stack and the self-luminous element of the second stack that emits light of the same color as a color of light emitted by the self-luminous element of the first stack are arranged at a second pitch larger than the first pitch.
Pulsed backlight unit in liquid crystal display device
To increase the spatial resolution of a liquid crystal display (LCD) device, instead of emitting colors of an image (e.g., the three primary colors) in a single frame, the colors of an image are emitted sequentially. For example, if the colors of the image are red, blue, and green, the colors are emitted sequentially at a rate three times the desired frame rate of the display. The colors are emitted from a backlight unit (BLU) that produces pulses of colored light successively. By emitting colors sequentially, the number of subpixels in a pixel can be decreased or eliminated. Thus, among other advantages, the size of each pixel can decrease and the spatial resolution of the display device (e.g., pixels per inch) can increase.
