Methods and systems for a liquid crystal display (LCD) device including a backlight with a plurality of light sources (e.g., light emitting diodes (LEDs)) are provided. The LCD device includes an LCD panel and a backlight for illuminating the LCD panel. The backlight includes a plurality of LEDs and a directional light guide plate. The directional light guide plate may be sectioned into quadrants. The plurality of light sources may be stacked and disposed behind the LCD panel positioned relative to directional light guide plate rotation. In an example, the LCD device may include a collimating layer and an extracting layer such that an extraction is variable.
