摘要:
A liquid crystal display (LCD) device is driven in interlaced scan to accommodate for liquid crystal (LC) setting times without sacrificing brightness. The LCD device includes an LCD panel including a first group of (e.g., even) pixel lines and a second group (e.g., odd) pixel lines, a backlight disposed behind the LCD panel to emit light toward the even and odd pixel lines, a shift grating disposed between the LCD and the backlight, the shift grating configured to block the light from the backlight from reaching either the first group of pixel lines or the second group of pixel lines, and a controller. The controller drives the LCD panel using an interlaced scan, coordinates the activation of the backlight (e.g., a strobed backlight), and changes the state of the shift grating to block the light from the backlight from reaching either the first group of pixel lines or the second group of pixel lines.
