The switching speed of the FLC material makes this possible. Since each LED is on only when needed, no color filters are re-quired, and power efficiency is minimized. The whitepoint of the display can be adjusted over a wide range by adjusting the relative brightnesses of the LEDs. Every pixel in the display produces all the primary colors. The subpixels, or color triads, required in typical LCD displays are not needed.
Time sharing on one pixel produces a sharper line than having subpixels.
The absence of subpixels allows for a high fill factor without the use of a black matrix. The spaces between pixels are on the order of the wavelength of visible light. Light going between the pixel mirrors gets refracted at large angles, and very little of it becomes part of the image. The small size of the display is also considered an advantage from a yield and cost perspective. A smaller die leads to a smaller probability of having a killer defect as well as more die per wafer.
