We demonstrate the optical reconstruction of a holographic image using a fabricated ferroelectric liquid crystal cell comprising 9,600 × 16,000 pixels with a pitch of 1 µm × 1 µm. The cell was driven by low voltage (±0.55 V0-p) and high frequency (1,080 Hz). This demonstrates the potential for realizing a color holographic display capable of reducing speckle noise by superposing multiple images.
